ORDER OF THE BOARD (by T.E. Johnson):

SUMMARY OF THIS ACTION

The Board today proposes amendments to the Illinois regulations that are “identical in

substance” to wastewater pretreatment and drinking water regulations adopted by the United

States Environmental Protection Agency (USEPA). The amendments involved in this

consolidated docket incorporate into the Illinois wastewater pretreatment and drinking water

regulations amendments in response to two USEPA actions. Those actions span the two

identical-in-substance update periods of January 1, 2007 through June 30, 2007 and July 1, 2007

through December 31, 2007. The Board has added a third set of USEPA amendments that

occurred later than these periods. The added later amendments are closely related to

amendments that occurred during the January 1, 2007 through June 30, 2007 time period.

The Board further finds that more time is necessary to complete these amendments and

extends the deadline for final action by this order. The deadline is extended from August 15,

2008 until December 1, 2008 pursuant to Section 7.2(b) of the Environmental Protection Act

(Act), 415 ILCS 5/7.2(b) (2006). The reasons for the extension are discussed in the

accompanying opinion also adopted today.

The R08-5 docket includes federal wastewater pretreatment amendments that USEPA

adopted in the period January 1, 2007 though June 30, 2007. On March 12, 2007, USEPA

adopted amendments relating to analytical methods approved under the wastewater pretreatment

and drinking water programs. The R08-5 docket includes the wastewater pretreatment segments

of those amendments.

The R08-7 docket includes federal Safe Drinking Water Act (SDWA) amendments that

USEPA adopted in the period January 1, 2007 though June 30, 2007, and on June 3, 2008. On

March 12, 2007, USEPA adopted amendments relating to analytical methods approved under the

wastewater pretreatment and drinking water programs. The R08-5 docket includes the drinking

water segments of those amendments. On June 3, 2008, USEPA approved alternative methods

for analysis under the drinking water program. The Board has added the June 3, 2008

amendments to the R08-5 docket due to their close relationship with the March 12, 2007

amendments.

The R08-13 docket includes federal SDWA amendments that USEPA adopted in the

period July 1, 2007 though December 31, 2007. On October 10, 2007, USEPA revised segments

of the Lead and Copper Rule under the drinking water regulations.

Sections 7.2 and 13.3 of the Act (415 ILCS 5/7.2 and 13.3 (2006)) require the Board to

adopt regulations that are “identical in substance” to federal wastewater pretreatment

regulations. The USEPA wastewater pretreatment rules implement Sections 307(b), (c), and (d)

and 402(b)(8) and (b)(9) of the Federal Water Pollution Control Act (FWPCA) (33 U.S.C.

§§ 1317(b), (c), and (d) and 1342(b)(8) and (b)(9) (2006)). The federal wastewater pretreatment

regulations are found at 40 C.F.R. 400 through 499. Section 13.3 also provides that Title VII of

the Act and Section 5 of the Administrative Procedure Act (APA) (5 ILCS 100/5-35 and 5-40

(2006)) do not apply to the Board’s adoption of identical-in-substance regulations.

Sections 7.2 and 17.5 of the Act (415 ILCS 5/7.2 and 17.5 (2006)) provide for quick

adoption by the Board of regulations that are identical in substance to federal regulations that

USEPA adopts to implement Sections 1412(b), 1414(c), 1417(a), and 1445(a) of the federal

SDWA (42 U.S.C. §§ 300g-1(a), 300g-3(c), 300g-6(a), and 300j-4(a) (2006)). The USEPA

National Primary Drinking Water Regulations (NPDWRs) implement Sections 1412(b), 1414(c),

1417(a), and 1445(a) of the federal SDWA (42 U.S.C. §§ 300g-1(a), 300g-3(c), 300g-6(a), and

300j-4(a) (2006)). The federal SDWA regulations are found at 40 C.F.R. 141 through 143.

Section 17.5 also provides that Title VII of the Act and Section 5 of the APA (5 ILCS 100/5-35

and 5-40 (2006)) do not apply to the Board’s adoption of identical-in-substance regulations.

This order is supported by an opinion that the Board also adopts today. The Board will

cause the proposed amendments to be published in the

Illinois Register

and will hold the docket

open to receive public comments for 45 days after the date of publication. The Board will then

adopt and file the final rules, taking into account the public comments received. The rules will

be adopted and filed no later than December 1, 2008, pursuant to the extension of the deadline

adopted by the Board in this opinion and order pursuant to Section 7.2(b) of the Act (415 ILCS

5/7.2(b) (2006)).

The Clerk is directed to cause the filing of the following proposed amendments with the

Office of the Secretary of State for their publication in the

Illinois Register

SUBPART G: LEAD AND COPPER

Section 611.350

General Requirements

Applicability and Scope

Applicability. The requirements of this Subpart G constitute national

primary drinking water regulations for lead and copper. This Subpart G

applies to all community water systems (CWSs) and non-transient, non-

community water systems (NTNCWSs).

Scope. This Subpart G establishes a treatment technique that includes

requirements for corrosion control treatment, source water treatment, lead

service line replacement, and public education. These requirements are

triggered, in some cases, by lead and copper action levels measured in

samples collected at consumers’ taps.

Definitions. For the purposes of only this Subpart G, the following terms have

the following meanings:

“Action level” means that concentration of lead or copper in water

computed pursuant to subsection (c) of this Section that determines, in

some cases, the treatment requirements of this Subpart G that a supplier

must complete. The action level for lead is 0.015 mg/ℓ. The action level

for copper is 1.3 mg/ℓ.

“Corrosion inhibitor” means a substance capable of reducing the

corrosivity of water toward metal plumbing materials, especially lead and

copper, by forming a protective film on the interior surface of those

materials.

“Effective corrosion inhibitor residual” means a concentration of inhibitor

in the drinking water sufficient to form a passivating film on the interior

walls of a pipe.

“Exceed,” as this term is applied to either the lead or the copper action

level, means that the 90th percentile level of the supplier’s samples

collected during a six-month monitoring period is greater than the action

level for that contaminant.

“First draw sample” means a one-liter sample of tap water, collected in

accordance with Section 611.356(b)(2), that has been standing in

plumbing pipes for at least six hours and which is collected without

flushing the tap.

“Large system” means a water system that regularly serves water to more

than 50,000 persons.

“Lead service line” means a service line made of lead that connects the

water main to the building inlet, including any lead pigtail, gooseneck, or

other fitting that is connected to such lead line.

“Maximum permissible concentration” or “MPC” means that

concentration of lead or copper for finished water entering the supplier’s

distribution system, designated by the Agency by a SEP pursuant to

Sections 611.110 and 611.353(b) that reflects the contaminant removal

capability of the treatment properly operated and maintained.

BOARD NOTE: Derived from 40 CFR 141.83(b)(4) (2002) (2007). (See

Section 611.353(b)(4)(B).)

“Medium-sized system” means a water system that regularly serves water

to more than 3,300 up to 50,000 or fewer persons.

“Meet,” as this term is applied to either the lead or the copper action level,

means that the 90th percentile level of the supplier’s samples collected

during a six-month monitoring period is less than or equal to the action

level for that contaminant.

“Method detection limit” or “MDL” is as defined at Section 611.646(a).

The MDL for lead is 0.001 mg/ℓ. The MDL for copper is 0.001 mg/ℓ, or

0.020 mg/ℓ by atomic absorption direct aspiration method.

BOARD NOTE: Derived from 40 CFR 141.89(a)(1)(iii) (2002) (2007).

“Monitoring period” means any of the six-month periods of time during

which a supplier must complete a cycle of monitoring under this Subpart

BOARD NOTE: USEPA refers to these as “monitoring periods.” The

Board uses “six-month monitoring period” to avoid confusion with

“compliance period,” as used elsewhere in this Part and defined at Section

611.101.

“Multiple-family residence” means a building that is currently used as a

multiple-family residence, but not one that is also a “single-family

structure.”

“90th percentile level” means that concentration of lead or copper

contaminant exceeded by ten percent or fewer of all samples collected

during a six-month monitoring period pursuant to Section 611.356 (i.e.,

that concentration of contaminant greater than or equal to the results

obtained from 90 percent of the samples). The 90th percentile levels for

copper and lead must be determined pursuant to subsection (c)(3) of this

Section.

BOARD NOTE: Derived from 40 CFR 141.80(c) (2002) (2007).

“Optimal corrosion control treatment” means the corrosion control

treatment that minimizes the lead and copper concentrations at users’ taps

while ensuring that the treatment does not cause the water system to

violate any national primary drinking water regulations.

“Practical quantitation limit” or “PQL” means the lowest concentration of

a contaminant that a well-operated laboratory can reliably achieve within

specified limits of precision and accuracy during routine laboratory

operating conditions. The PQL for lead is 0.005 mg/ℓ. The PQL for

copper is 0.050 mg/ℓ.

BOARD NOTE: Derived from 40 CFR 141.89(a)(1)(ii) and (a)(1)(iv)

(2002)

(2007).

“Service line sample” means a one-liter sample of water, collected in

accordance with Section 611.356(b)(3), that has been standing for at least

six hours in a service line.

“Single-family structure” means a building that was constructed as a

single-family residence and which is currently used as either a residence

or a place of business.

“Small system” means a water system that regularly serves water to 3,300

or fewer persons.

BOARD NOTE: Derived from 40 CFR 141.2 (2002) (2007).

Lead and Copper Action Levels.

The lead action level is exceeded if the 90th percentile lead level is greater

than 0.015 mg/ℓ.

The copper action level is exceeded if the 90th percentile copper level is

greater than 1.3 mg/ℓ.

Suppliers must compute the 90th percentile lead and copper levels as

follows:

List the results of all lead or copper samples taken during a six-

month monitoring period in ascending order, ranging from the

sample with the lowest concentration first to the sample with the

highest concentration last. Assign each sampling result a number,

ascending by single integers beginning with the number 1 for the

sample with the lowest contaminant level. The number assigned to

the sample with the highest contaminant level must be equal to the

total number of samples taken.

Determine the number for the 90th percentile sample by

multiplying the total number of samples taken during the six-

month monitoring period by 0.9.

The contaminant concentration in the sample with the number

yielded by the calculation in subsection (c)(3)(B) of this Section is

the 90th percentile contaminant level.

For suppliers that collect five samples per six-month monitoring

period, the 90th percentile is computed by taking the average of

the highest and second highest concentrations.

For a supplier that has been allowed by the Agency to collect

fewer than five samples in accordance with Section 611.356(c), the

sample result with the highest concentration is considered the 90th

percentile value.

Corrosion Control Treatment Requirements.

All suppliers must install and operate optimal corrosion control treatment.

Any supplier that complies with the applicable corrosion control treatment

requirements specified by the Agency pursuant to Sections 611.351 and

611.352 is deemed in compliance with the treatment requirement of

subsection (d)(1) of this Section.

Source water treatment requirements. Any supplier whose system exceeds the

lead or copper action level must implement all applicable source water treatment

requirements specified by the Agency pursuant to Section 611.353.

Lead service line replacement requirements. Any supplier whose system exceeds

the lead action level after implementation of applicable corrosion control and

source water treatment requirements must complete the lead service line

replacement requirements contained in Section 611.354.

Public education requirements. Pursuant to Section 611.355, the supplier must

provide a consumer notice of the lead tap water monitoring results to the persons

served at each site (tap) that is tested. Any supplier whose system exceeds the

lead action level must implement the public education requirements contained in

Section 611.355.

Monitoring and analytical requirements. Suppliers must complete all tap water

monitoring for lead and copper, monitoring for water quality parameters, source

water monitoring for lead and copper, and analyses of the monitoring results

under this Subpart G in compliance with Sections 611.356, 611.357, 611.358, and

611.359.

Reporting requirements. Suppliers must report to the Agency any information

required by the treatment provisions of this Subpart G and Section 611.360.

Recordkeeping requirements. Suppliers must maintain records in accordance

with Section 611.361.

Violation of national primary drinking water regulations. Failure to comply with

the applicable requirements of this Subpart G, including conditions imposed by

the Agency by SEP pursuant to these provisions and Section 611.110, will

constitute a violation of the national primary drinking water regulations for lead

or copper.

BOARD NOTE: Derived from 40 CFR 141.80 (2002)

(2007), as amended at 57782 (October 12,

2007).

(Source: Amended at 32 Ill. Reg. ________, effective ______________________)

Section 611.351

Applicability of Corrosion Control

Corrosion control required. Suppliers must complete the applicable corrosion

control treatment requirements described in Section 611.352 on or before the

deadlines set forth in this Section.

Large systems. Each large system supplier (one regularly serving more

than 50,000 persons) must complete the corrosion control treatment steps

specified in subsection (d) of this Section, unless it is deemed to have

optimized corrosion control under subsection (b)(2) or (b)(3) of this

Section.

Medium-sized and small systems. Each small system supplier (one

regularly serving 3,300 or fewer persons) and each medium-sized system

(one regularly serving more than 3,300 up to 50,000 persons) must

complete the corrosion control treatment steps specified in subsection (e)

of this Section, unless it is deemed to have optimized corrosion control

under one of subsections (b)(1), (b)(2), or (b)(3) of this Section.

Suppliers deemed to have optimized corrosion control. A supplier is deemed to

have optimized corrosion control, and is not required to complete the applicable

corrosion control treatment steps identified in this Section, if the supplier satisfies

one of the criteria specified in subsections (b)(1) through (b)(3) of this Section.

Any such system deemed to have optimized corrosion control under this

subsection, and which has treatment in place, must continue to operate and

maintain optimal corrosion control treatment and meet any requirements that the

Agency determines are appropriate to ensure optimal corrosion control treatment

is maintained.

Small- or medium-sized system meeting action levels. A small system or

medium-sized system supplier is deemed to have optimized corrosion

control if the system meets the lead and copper action levels during each

of two consecutive six-month monitoring periods with monitoring

conducted in accordance with Section 611.356.

SEP for equivalent activities to corrosion control. The Agency must, by a

SEP granted pursuant to Section 611.110, deem any supplier to have

optimized corrosion control treatment if it determines that the supplier has

conducted activities equivalent to the corrosion control steps applicable

under this Section. In making this determination, the Agency must specify

the water quality control parameters representing optimal corrosion

control in accordance with Section 611.352(f). A water supplier that is

deemed to have optimized corrosion control under this subsection (b)(2)

must operate in compliance with the Agency-designated optimal water

quality control parameters in accordance with Section 611.352(g) and

must continue to conduct lead and copper tap and water quality parameter

sampling in accordance with Sections 611.356(d)(3) and 611.357(d),

respectively. A supplier must provide the Agency with the following

information in order to support an Agency SEP determination under this

subsection (b)(2):

The results of all test samples collected for each of the water

quality parameters in Section 611.352(c)(3);

A report explaining the test methods the supplier used to evaluate

the corrosion control treatments listed in Section 611.352(c)(1), the

results of all tests conducted, and the basis for the supplier’s

selection of optimal corrosion control treatment;

A report explaining how the supplier has installed corrosion

control and how the supplier maintains it to insure minimal lead

and copper concentrations at consumer’s taps; and

The results of tap water samples collected in accordance with

Section 611.356 at least once every six months for one year after

corrosion control has been installed.

Results less than practical quantitation level (PQL) for lead. Any supplier

is deemed to have optimized corrosion control if it submits results of tap

water monitoring conducted in accordance with Section 611.356 and

source water monitoring conducted in accordance with Section 611.358

that demonstrate that for two consecutive six-month monitoring periods

the difference between the 90th percentile tap water lead level, computed

pursuant to Section 611.350(c)(3), and the highest source water lead

concentration is less than the practical quantitation level for lead specified

in Section 611.359(a)(1)(B)(i).

Those systems whose highest source water lead level is below the

method detection limit (MDL) may also be deemed to have

optimized corrosion control under this subsection (b) if the 90th

percentile tap water lead level is less than or equal to the PQL for

lead for two consecutive six-month monitoring periods.

Any water system deemed to have optimized corrosion control in

accordance with this subsection (b) must continue monitoring for

lead and copper at the tap no less frequently than once every three

calendar years using the reduced number of sites specified in

Section 611.356(c) and collecting the samples at times and

locations specified in Section 611.356(d)(4)(D). Any such system

that has not conducted a round of monitoring pursuant to Section

611.356(d) since September 30, 1997, must have completed a

round of monitoring pursuant to this subsection (b) no later than

September 30, 2000.

Any water system deemed to have optimized corrosion control

pursuant to this subsection (b) must notify the Agency in writing

pursuant to Section 611.360(a)(3) of any upcoming long-term

change in treatment or the addition of a new source, as described in

that Section. The Agency must require any such system to conduct

additional monitoring or to take other action if the Agency

determines that the additional monitoring is necessary and

appropriate to ensure that the supplier maintains minimal levels of

corrosion in its distribution system review and approve the

addition of a new source or any long-term change in water

treatment before the addition or long-term change is implemented

by the water system.

As of July 12, 2001, a A supplier is not deemed to have optimized

corrosion control under this subsection (b), and must implement

corrosion control treatment pursuant to subsection (b)(3)(E) of this

Section, unless it meets the copper action level.

Any supplier triggered into corrosion control because it is no

longer deemed to have optimized corrosion control under this

subsection must implement corrosion control treatment in

accordance with the deadlines in subsection (e) of this Section.

Any such large system supplier must adhere to the schedule

specified in that subsection (e) for a medium-sized system

supplier, with the time periods for completing each step being

triggered by the date the supplier is no longer deemed to have

optimized corrosion control under this subsection (b).

Suppliers not required to complete corrosion control steps for having met both

action levels.

Any small system or medium-sized system supplier, otherwise required to

complete the corrosion control steps due to its exceedence of the lead or

copper action level, may cease completing the treatment steps after the

supplier has fulfilled both of the following conditions:

It has met both the copper action level and the lead action level

during each of two consecutive six-month monitoring periods

conducted pursuant to Section 611.356; and

The supplier has submitted the results for those two consecutive

six-month monitoring periods to the Agency.

A supplier that has ceased completing the corrosion control steps pursuant

to subsection (c)(1) of this Section (or the Agency, if appropriate) must

resume completion of the applicable treatment steps, beginning with the

first treatment step that the supplier previously did not complete in its

entirety, if the supplier thereafter exceeds the lead or copper action level

during any monitoring period.

The Agency may, by SEP, require a supplier to repeat treatment steps

previously completed by the supplier where it determines that this is

necessary to properly implement the treatment requirements of this

Section. Any such SEP must explain the basis for this decision.

The requirement for any small- or medium-sized system supplier to

implement corrosion control treatment steps in accordance with subsection

(e) of this Section (including systems deemed to have optimized corrosion

control under subsection (b)(1) of this Section) is triggered whenever any

small- or medium-sized system supplier exceeds the lead or copper action

level.

Treatment steps and deadlines for large systems. Except as provided in

subsections (b)(2) and (b)(3) of this Section, large system suppliers must

complete the following corrosion control treatment steps (described in the

referenced portions of Sections 611.352, 611.356, and 611.357) on or before the

indicated dates.

Step 1: The supplier must have conducted initial monitoring (Sections

611.356(d)(1) and 611.357(b)) during two consecutive six-month

monitoring periods on or before January 1, 1993.

Step 2: The supplier must have completed corrosion control studies

(Section 611.352(c)) on or before July 1, 1994.

Step 3: The Agency must have approved optimal corrosion control

treatment (Section 611.352(d)) by a SEP issued pursuant to Section

611.110 on or before January 1, 1995.

Step 4: The supplier must have installed optimal corrosion control

treatment (Section 611.352(e)) by January 1, 1997.

Step 5: The supplier must have completed follow-up sampling (Sections

611.356(d)(2) and 611.357(c)) by January 1, 1998.

Step 6: The Agency must have reviewed installation of treatment and

approve optimal water quality control parameters (Section 611.352(f)) by

July 1, 1998.

Step 7: The supplier must operate in compliance with the Agency-

specified optimal water quality control parameters (Section 611.352(g))

and continue to conduct tap sampling (Sections 611.356(d)(3) and

611.357(d)).

Treatment steps and deadlines for small- and medium-sized system suppliers.

Except as provided in subsection (b) of this Section, small- and medium-sized

system suppliers must complete the following corrosion control treatment steps

(described in the referenced portions of Sections 611.352, 611.356, and 611.357)

by the indicated time periods.

Step 1: The supplier must conduct initial tap sampling (Sections

611.356(d)(1) and 611.357(b)) until the supplier either exceeds the lead

action level or the copper action level or it becomes eligible for reduced

monitoring under Section 611.356(d)(4). A supplier exceeding the lead

action level or the copper action level must recommend optimal corrosion

control treatment (Section 611.352(a)) within six months after the end of

the monitoring period during which it exceeds one of the action levels.

Step 2: Within 12 months after the end of the monitoring period during

which a supplier exceeds the lead action level or the copper action level,

the Agency may require the supplier to perform corrosion control studies

(Section 611.352(b)). If the Agency does not require the supplier to

perform such studies, the Agency must, by a SEP issued pursuant to

Section 611.110, specify optimal corrosion control treatment (Section

611.352(d)) within the appropriate of the following timeframes:

for For medium-sized systems, within 18 months after the end of

the monitoring period during which such supplier exceeds the lead

action level or the copper action level,; or

for For small systems, within 24 months after the end of the

monitoring period during which such supplier exceeds the lead

action level or the copper action level.

Step 3: If the Agency requires a supplier to perform corrosion control

studies under step 2 (subsection (e)(2) of this Section), the supplier must

complete the studies (Section 611.352(c)) within 18 months after the

Agency requires that such studies be conducted.

Step 4: If the supplier has performed corrosion control studies under step

2 (subsection (e)(2) of this Section), the Agency must, by a SEP issued

pursuant to Section 611.110, approve optimal corrosion control treatment

(Section 611.352(d)) within six months after completion of step 3

(subsection (e)(3) of this Section).

Step 5: The supplier must install optimal corrosion control treatment

(Section 611.352(e)) within 24 months after the Agency approves such

treatment.

Step 6: The supplier must complete follow-up sampling (Sections

611.356(d)(2) and 611.357(c)) within 36 months after the Agency

approves optimal corrosion control treatment.

Step 7: The Agency must review the supplier’s installation of treatment

and, by a SEP issued pursuant to Section 611.110, approve optimal water

quality control parameters (Section 611.352(f)) within six months after

completion of step 6 (subsection (e)(6) of this Section).

Step 8: The supplier must operate in compliance with the Agency-

approved optimal water quality control parameters (Section 611.352(g))

Section 611.353

Source Water Treatment

Suppliers must complete the applicable source water monitoring and treatment requirements

(described in the referenced portions of subsection (b) of this Section, and in Sections 611.356

and 611.358) by the following deadlines.

Deadlines for completing source water treatment steps.

Step 1: A supplier exceeding the lead action level or the copper action

level must complete lead and copper and source water monitoring (Section

611.358(b)) and make a treatment recommendation to the Agency

(subsection (b)(1) of this Section) within six months 180 days after

exceeding the end of the monitoring period during which the supplier

exceeded the pertinent action level.

Step 2: The Agency must, by a SEP issued pursuant to Section 611.110,

make a determination regarding source water treatment (subsection (b)(2)

of this Section) within six months after submission of monitoring results

under step 1.

Step 3: If the Agency requires installation of source water treatment, the

supplier must install that treatment (subsection (b)(3) of this Section)

within 24 months after completion of step 2.

Step 4: The supplier must complete follow-up tap water monitoring

(Section 611.356(d)(2)) and source water monitoring (Section 611.358(c))

within 36 months after completion of step 2.

Step 5: The Agency must, by a SEP issued pursuant to Section 611.110,

review the supplier’s installation and operation of source water treatment

and specify MPCs for lead and copper (subsection (b)(4) of this Section)

within six months after completion of step 4.

Step 6: The supplier must operate in compliance with the Agency-

specified lead and copper MPCs (subsection (b)(4) of this Section) and

continue source water monitoring (Section 611.358(d)).

Description of Source Water Treatment Requirements.

System treatment recommendation. Any supplier that exceeds the lead

action level or the copper action level must recommend in writing to the

Agency the installation and operation of one of the source water

treatments listed in subsection (b)(2) of this Section. A supplier may

recommend that no treatment be installed based on a demonstration that

source water treatment is not necessary to minimize lead and copper levels

at users’ taps.

Agency determination regarding source water treatment.

The Agency must complete an evaluation of the results of all

source water samples submitted by the supplier to determine

whether source water treatment is necessary to minimize lead or

copper levels in water delivered to users’ taps.

If the Agency determines that treatment is needed, the Agency

must, by a SEP issued pursuant to Section 611.110, either require

installation and operation of the source water treatment

recommended by the supplier (if any) or require the installation

and operation of another source water treatment from among the

following:

ion exchange;

ii)

reverse osmosis;

iii)

lime softening; or

iv)

coagulation/filtration.

The Agency may request and the supplier must submit such

additional information, on or before a certain date, as the Agency

determines is necessary to aid in its review.

The Agency must notify the supplier in writing of its determination

and set forth the basis for its decision.

Installation of source water treatment. Each supplier must properly install

and operate the source water treatment approved by the Agency under

subsection (b)(2) of this Section.

Agency review of source water treatment and specification of maximum

permissible source water levels (MPCs).

The Agency must review the source water samples taken by the

supplier both before and after the supplier installs source water

treatment, and determine whether the supplier has properly

installed and operated the approved source water treatment.

Based on its review, the Agency must, by a SEP issued pursuant to

Section 611.110, approve the lead and copper MPCs for finished

water entering the supplier’s distribution system. Such levels must

reflect the contaminant removal capability of the treatment

properly operated and maintained.

The Agency must explain the basis for its decision under

subsection (b)(4)(B) of this Section.

Continued operation and maintenance. Each supplier must maintain lead

and copper levels below the MPCs approved by the Agency at each

sampling point monitored in accordance with Section 611.358. The

supplier is out of compliance with this subsection if the level of lead or

copper at any sampling point is greater than the MPC approved by the

Agency pursuant to subsection (b)(4)(B) of this Section.

Modification of Agency treatment decisions.

On its own initiative, or in response to a request by a supplier, the

Agency may, by a SEP issued pursuant to Section 611.110, modify

its determination of the source water treatment under subsection

(b)(2) of this Section, or the lead and copper MPCs under

subsection (b)(4) of this Section.

A request for modification by a supplier must be in writing,

explain why the modification is appropriate, and provide

supporting documentation.

The Agency may, by a SEP issued pursuant to Section 611.110,

modify its determination where it concludes that such change is

necessary to ensure that the supplier continues to minimize lead

and copper concentrations in source water.

A revised determination made pursuant to subsection (b)(6)(C) of

this Section must set forth the new treatment requirements, explain

the basis for the Agency’s decision, and provide an

implementation schedule for completing the treatment

modifications.

Any interested person may submit information to the Agency, in

writing, that bears on whether the Agency should, within its

discretion, issue a SEP to modify its determination pursuant to

subsection (h)(1) of this Section. An Agency determination not to

act on a submission of such information by an interested person is

not an Agency determination for the purposes of Sections 39 and

40 of the Act [415 ILCS 5/39 and 40].

Treatment decisions by USEPA. Pursuant to the procedures in 40 CFR

142.19, the USEPA Regional Administrator reserves the prerogative to

review treatment determinations made by the Agency under subsections

(b)(2), (b)(4), or (b)(6) of this Section and issue federal treatment

determinations consistent with the requirements of 40 CFR 141.83(b)(2),

(b)(4), and (b)(6), where the Administrator finds that the following is true:

the Agency has failed to issue a treatment determination by the

applicable deadline contained in subsection (a) of this Section;

the Agency has abused its discretion in a substantial number of

cases or in cases affecting a substantial population; or

the technical aspects of the Agency’s determination would be

indefensible in an expected federal enforcement action taken

against a supplier.

Section 611.354

Lead Service Line Replacement

Suppliers required to replace lead service lines.

If the results from tap samples taken pursuant to Section 611.356(d)(2)

exceed the lead action level after the supplier has installed corrosion

control or source water treatment (whichever sampling occurs later), the

supplier must recommence replacing lead service lines in accordance with

the requirements of subsection (b) of this Section.

If a supplier is in violation of Section 611.351 or Section 611.353 for

failure to install source water or corrosion control treatment, the Agency

may, by a SEP issued pursuant to Section 611.110, require the supplier to

commence lead service line replacement under this Section after the date

by which the supplier was required to conduct monitoring under Section

611.356(d)(2) has passed.

Annual replacement of lead service lines.

Initiation of a lead service line replacement program.

1A)

A supplier that is required to commence lead service line

replacement pursuant to subsection (a) of this Section must

annually replace at least seven percent of the initial number of lead

service lines in its distribution system.

2B)

The initial number of lead service lines is the number of lead lines

in place at the time the replacement program begins.

C3)

The supplier must identify the initial number of lead service lines

in its distribution system, including an identification of the

portions of the system owned by the supplier, based on a materials

evaluation, including the evaluation required under Section

611.356(a) and relevant legal authorities (e.g., contracts, local

ordinances) regarding the portion owned by the system.

4D)

The first year of lead service line replacement must begin on the

date first day following the end of the monitoring period in which

the supplier exceeded the action level in tap sampling referenced in

pursuant to subsection (a) of this Section.

If monitoring is required annually or less frequently, the end of the

monitoring period is September 30 of the calendar year in which

the sampling occurs.

If the Agency has established an alternate monitoring period by a

SEP issued pursuant to Section 611.110, then the end of the

monitoring period will be the last day of that period.

Resumption of a lead service line replacement program after cessation.

A supplier that is resuming a program after cessation of its lead

service line replacement program, as allowed pursuant to

subsection (f) of this Section must update its inventory of lead

service lines to include those sites that it had previously

determined did not require replacement pursuant to the sampling

provision of subsection (c) of this Section.

The supplier will then divide the updated number of remaining

lead service lines by the number of remaining years in the program

to determine the number of lines that must be replaced per year

(seven percent lead service line replacement is based on a 15-year

replacement program, so that, for example, a supplier resuming

lead service line replacement after previously conducting two

years of replacement would divide the updated inventory by 13).

For a supplier that has completed a 15-year lead service line

replacement program, the Agency must, by a SEP issued pursuant

to Section 611.110, determine a schedule for replacing or retesting

lines that were previously tested out under the completed

replacement program, whenever the supplier has re-exceeded the

action level.

Service lines not needing replacement. A supplier is not required to replace any

individual lead service line for which the lead concentrations in all service line

samples taken from that line pursuant to Section 611.356(b)(3) are less than or

equal to 0.015 mg/ℓ.

A water supplier must replace that portion of the lead service line that it owns. In

cases where the supplier does not own the entire lead service line, the supplier

must notify the owner of the line, or the owner’s authorized agent, that the

supplier will replace the portion of the service line that it owns and must offer to

replace the owner’s portion of the line. A supplier is not required to bear the cost

of replacing the privately-owned portion of the line, nor is it required to replace

the privately-owned portion where the owner chooses not to pay the cost of

replacing the privately-owned portion of the line, or where replacing the

privately-owned portion would be precluded by State, local, or common law. A

water supplier that does not replace the entire length of the service line also must

complete the following tasks:

Notice Prior to Commencement of Work.

At least 45 days prior to commencing the partial replacement of a

lead service line, the water supplier must provide notice to the

residents of all buildings served by the line explaining that they

may experience a temporary increase of lead levels in their

drinking water, along with guidance on measures consumers can

take to minimize their exposure to lead.

The Agency, by issuing an appropriate SEP, may allow the water

supplier to provide notice under the previous sentence less than 45

days prior to commencing partial lead service line replacement

where it determines that such replacement is in conjunction with

emergency repairs.

In addition, the water supplier must inform the residents served by

the line that the supplier will, at the supplier’s expense, collect a

sample from each partially-replaced lead service line that is

representative of the water in the service line for analysis of lead

content, as prescribed by Section 611.356(b)(3), within 72 hours

after the completion of the partial replacement of the service line.

The supplier must collect the sample and report the results of the

analysis to the owner and the residents served by the line within

three business days of receiving the results.

Mailed notices post-marked within three business days of

receiving the results must be considered “on time.”

The water supplier must provide the information required by subsection

(d)(1) of this Section to the residents of individual dwellings by mail or by

other methods approved by the Agency by a SEP issued pursuant to

Section 611.110. In instances where multi-family dwellings are served by

the service line, the water supplier must have the option to post the

information at a conspicuous location.

Agency determination of shorter replacement schedule.

The Agency must, by a SEP issued pursuant to Section 611.110, require a

supplier to replace lead service lines on a shorter schedule than that

otherwise required by this Section if it determines, taking into account the

number of lead service lines in the system, that such a shorter replacement

schedule is feasible.

The Agency must notify the supplier of its finding pursuant to subsection

(e)(1) of this Section within six months after the supplier is triggered into

lead service line replacement based on monitoring, as referenced in

subsection (a) of this Section.

Cessation of service line replacement.

Any supplier may cease replacing lead service lines whenever it fulfills

both of the following conditions:

First draw tap samples collected pursuant to Section 611.356(b)(2)

meet the lead action level during each of two consecutive six-

month monitoring periods; and

The supplier has submitted those results to the Agency.

If any of the supplier’s first draw tap samples thereafter exceed the lead

action level, the supplier must recommence replacing lead service lines

pursuant to subsection (b)(2) of this Section.

To demonstrate compliance with subsections (a) through (d) of this Section, a

supplier must report to the Agency the information specified in Section

611.360(e).

Section 611.355

Public Education and Supplemental Monitoring

A supplier that exceeds the lead action level based on tap water samples collected in accordance

with Section 611.356 must deliver the public education materials required by subsections

subsection (a) and (b) of this Section in accordance with the requirements of subsection (c) (b) of

this Section. A supplier that exceeds the lead action level must sample the tap water of any

customer who requests it in accordance with subsection (c) of this Section. A supplier must

deliver a consumer notice of lead tap water monitoring results to persons who are served by the

supplier at each site that the supplier has tested, as specified in subsection (d) of this Section.

Content of written public education materials.

Community water systems and non-transient non-community water

systems. A CWS or NTNCWS supplier must include the text set forth in

Appendix E of this Part in all of the printed materials it distributes through

its lead public education program. following elements in printed materials

(e.g., brochures and pamphlets) in the same order as listed below. A

supplier may delete information pertaining to lead service lines, upon

approval by the Agency by a SEP issued pursuant to Section 611.110, if

no lead service lines exist anywhere in the water system service area.

Public education language at paragraphs (4)(B)(5) and (4)(D)(2) of

Appendix E of this Part may be modified regarding building permit record

availability and consumer access to these records, if approved by the

Agency by a SEP issued pursuant to Section 611.110. A supplier may

also continue to utilize pre-printed materials that meet the public

education language requirements in 40 CFR 141.85 (1991). Any

additional information presented by a supplier must be consistent with the

information in Appendix E of this Part and be in plain English that can be

understood by lay persons. In addition, the supplier must include the

language set forth in subsections (a)(1)(A), (a)(1)(B), and (a)(1)(F) of this

Section in the materials, exactly as written, except for the text in brackets

in these subsections, for which the supplier must include system-specific

information. Any additional information presented by a supplier must be

consistent with the information set forth below, and the supplier must

present the additional information in plain language that can be

understood by the general public. The supplier must submit all written

public education materials to the Agency prior to delivery, as required by

subsection (a)(3) of this Section.

BOARD NOTE: At corresponding 40 CFR 141.85(a)(1) (2002), USEPA

allowed the use of pre-printed copies of the public notices whose content

met the requirements of the original lead and copper rule adopted on June

7, 1991 (56 Fed. Reg. 26548). Rather than reference a prior version of

this Section of the Illinois rules, the Board has retained the federal

reference to the prior requirements.

IMPORTANT INFORMATION ABOUT LEAD IN YOUR

DRINKING WATER. [INSERT NAME OF SUPPLIER] found

elevated levels of lead in drinking water in some homes/buildings.

Lead can cause serious health problems, especially for pregnant

women and young children. Please read this information closely to

see what you can do to reduce lead in your drinking water.

BOARD NOTE: The supplier must use the verbatim text set forth

in this subsection (a)(1)(A), with the exception that the supplier

must insert its name in place of the bracketed text.

Health effects of lead. Lead can cause serious health problems if

too much enters your body from drinking water or other sources.

It can cause damage to the brain and kidneys, and can interfere

with the production of red blood cells that carry oxygen to all parts

of your body. The greatest risk of lead exposure is to infants,

young children, and pregnant women. Scientists have linked the

effects of lead on the brain with lowered IQ in children. Adults

with kidney problems and high blood pressure can be affected by

low levels of lead more than healthy adults. Lead is stored in the

bones, and it can be released later in life. During pregnancy, the

child receives lead from the mother’s bones, which may affect

brain development.

BOARD NOTE: The supplier must use the verbatim text set forth

in this subsection (a)(1)(B).

Sources of Lead.

Explain what lead is.

ii)

Explain possible sources of lead in drinking water and how

lead enters drinking water. Include information on home

and building plumbing materials and service lines that may

contain lead.

iii)

Discuss other important sources of lead exposure in

addition to drinking water (e.g., paint).

BOARD NOTE: The supplier must use text that provides the

information described in this subsection (a)(1)(C).

Discuss the steps the consumer can take to reduce his or her

exposure to lead in drinking water.

Encourage running the water to flush out the lead.

ii)

Explain concerns with using hot water from the tap and

specifically caution against the use of hot water for

preparing baby formula.

iii)

Explain that boiling water does not reduce lead levels.

iv)

Discuss other options consumers can take to reduce

exposure to lead in drinking water, such as alternative

sources or treatment of water.

Suggest that parents have their child’s blood tested for lead.

BOARD NOTE: The supplier must use text that provides the

information described in this subsection (a)(1)(D).

Explain why there are elevated levels of lead in the supplier’s

drinking water (if known) and what the supplier is doing to reduce

the lead levels in homes and buildings in this area.

BOARD NOTE: The supplier must use text that provides the

information described in this subsection (a)(1)(E).

For more information, call us at [INSERT THE SUPPLIER’S

NUMBER] [(IF APPLICABLE), or visit our Web site at [INSERT

THE SUPPLIER’S WEB SITE HERE]]. For more information on

reducing lead exposure around your home/building and the health

effects of lead, visit USEPA’s Web site at

lead

or contact your health care provider.

BOARD NOTE: The supplier must use the verbatim text set forth

in this subsection (a)(1)(F), with the exception that the supplier

must insert its name in place of the first segment of bracketed text,

100

and it must add the second segment of bracketed text and substitute

its Web address for the internal bracketed text.

Non-transient non-community Community water systems. A NTNCWS

must either include the text In addition to including the elements specified

in subsection (a)(1) of this Section or must include the text set forth in

Appendix F of this Part in all of the printed materials it distributes through

its lead public education program. A water supplier may delete

information pertaining to lead service lines upon approval by the Agency

by a SEP issued pursuant to Section 611.110 if no lead service lines exist

anywhere in the water system service area. Any additional information

presented by a supplier must be consistent with the information below and

be in plain English that can be understood by lay persons. a CWS supplier

must do both of the following:

It must tell consumers how to get their water tested; and

It must discuss lead in plumbing components and the difference

between low-lead and lead-free components.

Agency review and approval of written public education materials.

The supplier must submit all written public education materials to

the Agency for review at least 60 days prior to its planned date for

delivery of the materials to the public.

If the Agency determines that the form and content of the

supplier’s written public education materials is adequate, it may

issued a SEP pursuant to Section 611.110 that expressly approves

of the materials.

A supplier may immediately distribute its written public education

materials after receipt of a SEP or a revised SEP that expressly

approves those materials.

If the Agency determines that the form or content of the written

public education materials submitted by the supplier does not

comply with the requirements of this Section, it must issue a SEP

pursuant to Section 611.110. The Agency may issue a revised SEP

that expressly supercedes a SEP previously issued under this

subsection (a)(1). Any SEP or revised SEP issued by the Agency

must identify any deficiencies in the written public education

materials with specificity sufficient to guide the supplier to their

correction in a way that would address the Agency’s concerns.

The Agency must issue any SEP or revised SEP under subsection

101

(a)(3)(D) of this Section no later than 30 days after the date on

which it received a copy of the supplier’s prospective written

public education materials, unless the Agency and the supplier

have agreed to a later date pursuant to subsection (a)(3)(F) of this

Section. The Agency and the supplier may agree to a longer time

within which the Agency may issue a SEP or a revised SEP, in

which case the Agency must issue the SEP or revised SEP before

expiration of the agreed longer time.

BOARD NOTE: The Board has provided that the Agency and the

supplier may agree to a longer time before the Agency issues a

SEP and for the Agency to issue a revised SEP that supercedes an

already-issued SEP, in order to allow for negotiation of any issues

and the quickest possible distribution of the materials.

If the supplier has not received a SEP from the Agency within 45

days after the date on which the Agency received its written public

education materials to the Agency, those materials are deemed

approved, and the supplier may immediately proceed to distribute

them.

Once the supplier has revised its written public education materials

exactly as described by the Agency in a SEP issued under

subsection (a)(3)(D) of this Section, those materials are deemed

approved, and the supplier may immediately proceed to distribute

them.

BOARD NOTE: At corresponding 40 CFR 141.85(a)(1) (2007), USEPA

allowed the State to require prior approval of written public information

materials. Rather than require prior Agency approval, the Board has

chosen to require submission to the Agency for review sufficiently in

advance of distribution to allow the Agency to raise any deficiencies that

it may perceive. The Board has used the mechanism of the SEP for the

Agency to communicate its concerns, as this would allow the supplier to

petition the Board for review of the Agency’s determination pursuant to

Section 611.110(c).

Content of broadcast materials. A supplier must include the following

information in all public service announcements submitted under its lead public

education program to television and radio stations for broadcast:

Why should everyone want to know the facts about lead and drinking

water? Because unhealthy amounts of lead can enter drinking water

through the plumbing in your home. That’s why I urge you to do what I

did. I had my water tested for (insert “free” or the cost per sample). You

can contact the (insert the name of the city or supplier) for information on

102

testing and on simple ways to reduce your exposure to lead in drinking

water.

public health concern, please call (insert the phone number of the city or

supplier).

cb)

Delivery of a public education program materials.

In communities where A supplier that serves a significant large proportion

of the population speaks a language other than non-English speaking

consumers, the public education materials must be communicated contain

information in the appropriate languages regarding the importance of the

notice, or it must contain a telephone number or address where a person

served may contact the supplier to obtain a translated copy of the public

education materials or to request assistance in the appropriate language.

A CWS supplier that exceeds the lead action level on the basis of tap

water samples collected in accordance with Section 611.356 and which is

not already repeating conducting public education tasks pursuant to

subsection (c)(3), (c)(7), or (c)(8) of this Section must, within 60 days

after the end of the monitoring period in which the exceedance occurred,

do each of the following complete the public education tasks according to

the following requirements:

Insert notices in each customer’s water utility bill or disseminate to

each customer by separately mailing a notice containing the

information required by subsection (a)(1) of this Section, along

with the following alert in large print on the water bill itself:

“SOME HOMES IN THIS COMMUNITY HAVE ELEVATED

LEAD LEVELS IN THEIR DRINKING WATER. LEAD CAN

POSE A SIGNIFICANT RISK TO YOUR HEALTH. PLEASE

READ THE ENCLOSED NOTICE FOR FURTHER

INFORMATION.” A CWS supplier having a billing cycle that

does not include a billing within 60 days after exceeding the action

level or a CWS supplier that cannot insert information in the water

utility bill without making major changes to its billing system may

use a separate mailing to deliver the information in subsection

(a)(1) of this Section, as long as the information is delivered to

each customer within 60 days of exceeding the action level. Such

a water supplier must also include the “alert” language specified in

this subsection (c)(2)(A);

Submit the information required by subsection (a)(1) of this

Section to the editorial departments of the major daily and weekly

newspapers circulated throughout the community;

largest audiences within the community served by the supplier.

The CWS supplier must deliver printed materials that meet the

content requirements of subsection (a) of this section to all of its

bill-paying customers.

Methods of delivery for a CWS supplier.

The CWS supplier must contact customers who are most at

risk by delivering education materials that meet the content

requirements of subsection (a) of this Section to local

public health agencies, even if the agencies are not located

within the supplier’s service area, along with an

informational notice that encourages distribution to all of

the agencies’ potentially affected customers or the

supplier’s users. The supplier must contact the local public

health agencies directly by phone or in person. The local

public health agencies may provide a specific list of

additional community-based organizations that serve the

target populations, which may include organizations

outside the service area of the supplier. If such lists are

provided, the supplier must deliver education materials that

meet the content requirements of subsection (a) of this

Section to each of the organizations on the provided lists.

and it does not separately charge for water consumption.

Reduced requirements for certain smaller CWS suppliers.

109

A CWS supplier serving 3,300 or fewer people may omit the task

contained in subsection (c)(2)(D) of this Section. As long as it

distributes notices containing the information contained in

Appendix E of this Part to every household served by the system,

such a supplier may further limit its public education programs as

follows:

A supplier serving 500 or fewer people may forego the task

contained in subsection (c)(2)(B) of this Section. Such a

system may limit the distribution of the public education

materials required under subsection (c)(2)(C) of this

Section to facilities and organizations served by the

supplier that are most likely to be visited regularly by

pregnant women and children, unless it is notified by the

Agency in writing that it must make a broader distribution.

ii)

If approved by the Agency by a SEP issued pursuant to

Section 611.110, a system serving 501 to 3,300 people may

omit the task in subsection (c)(2)(B) of this Section or limit

the distribution of the public education materials required

under subsection (c)(2)(C) of this Section to facilities and

organizations served by the system that are most likely to

be visited regularly by pregnant women and children.

A CWS supplier serving 3,300 or fewer people that delivers public

education in accordance with subsection (c)(8)(A) of this Section

must repeat the required public education tasks at least once during

each calendar year in which the supplier exceeds the lead action

level.

A CWS supplier that serves 3,300 or fewer people may limit certain

aspects of its public education programs as follows:

With respect to the requirements of subsection (b)(2)(F) of this

Section, a supplier that serves 3,300 or fewer must implement at

least one of the activities listed in that subsection.

With respect to the requirements of subsection (b)(2)(B) of this

Section, a supplier that serves 3,300 or fewer people may limit the

distribution of the public education materials required under that

subsection to facilities and organizations that it serves which are

most likely to be visited regularly by pregnant women and

children.

With respect to the requirements of subsection (b)(2)(E) of this

110

Section, the Agency may, by a SEP issued pursuant to Section

611.110, waive this requirement for a supplier that serves 3,300 or

fewer persons, as long as the supplier distributes notices to every

household that it serves.

dc)

Supplemental monitoring and notification of results. A supplier that fails to meet

the lead action level on the basis of tap samples collected in accordance with

Section 611.356 must offer to sample the tap water of any customer who requests

it. The supplier is not required to pay for collecting or analyzing the sample, nor

is the supplier required to collect and analyze the sample itself.

Requirement for consumer notice of tap water monitoring results.

Consumer notice requirement. A supplier must provide a notice of the

individual tap results from lead tap water monitoring carried out under the

requirements of Section 611.356 to the persons served by the water system

at the specific sampling site from which the sample was taken (e.g., the

occupants of the residence where the tap was tested).

Timing of consumer notice. The supplier must provide the consumer

notice as soon as practical, but no later than 30 days after it learns of the

tap monitoring results.

Content of consumer notice. The consumer notice must include the results

of lead tap water monitoring for the tap that was tested, an explanation of

the health effects of lead, list steps consumers can take to reduce exposure

to lead in drinking water, and contact information for the water utility.

The notice must also provide the maximum contaminant level goal and the

action level for lead and the definitions for these two terms from Section

611.883(c).

Delivery of consumer notice. The consumer notice must be provided to

persons served at the tap that was tested, either by mail or by another

method approved by the Agency, by a SEP issued pursuant to Section

611.110. For example, upon approval by the Agency, a NTNCWS

supplier could post the results on a bulletin board in the facility to allow

users to review the information. The supplier must provide the notice to

customers at sample taps tested, including consumers who do not receive

water bills.

Section 611.356

Tap Water Monitoring for Lead and Copper

Sample Sampling site location.

Selecting a pool of targeted sampling sites.

By the applicable date for commencement of monitoring under

subsection (d)(1) of this Section, each supplier must complete a

materials evaluation of its distribution system in order to identify a

pool of targeted sampling sites that meets the requirements of this

Section.

The pool of targeted sampling sites must be sufficiently large to

ensure that the supplier can collect the number of lead and copper

tap samples required by subsection (c) of this Section.

The supplier must select the sites for collection of first draw

samples from this pool of targeted sampling sites.

The supplier must not select as sampling sites any faucets that have

point-of-use or point-of-entry treatment devices designed to

remove or capable of removing inorganic contaminants.

Materials evaluation.

A supplier must use the information on lead, copper, and

galvanized steel collected pursuant to 40 CFR 141.42(d) (special

monitoring for corrosivity characteristics) when conducting a

materials evaluation.

When an evaluation of the information collected pursuant to 40

CFR 141.42(d) is insufficient to locate the requisite number of lead

and copper sampling sites that meet the targeting criteria in

subsection (a) of this Section, the supplier must review the

following sources of information in order to identify a sufficient

number of sampling sites:

All plumbing codes, permits, and records in the files of the

building departments that indicate the plumbing materials

that are installed within publicly- and privately-owned

structures connected to the distribution system;

ii)

All inspections and records of the distribution system that

indicate the material composition of the service

connections which connect a structure to the distribution

system;

112

iii)

All existing water quality information, which includes the

results of all prior analyses of the system or individual

structures connected to the system, indicating locations that

may be particularly susceptible to high lead or copper

concentrations; and

iv)

The supplier must seek to collect such information where

possible in the course of its normal operations (e.g.,

checking service line materials when reading water meters

or performing maintenance activities).

Tiers of sampling sites. Suppliers must categorize the sampling sites

within their pool according to the following tiers:

CWS Tier 1 sampling sites. “CWS Tier 1 sampling sites” must

include the following single-family structures:

Those that contain copper pipes with lead solder installed

after 1982 or which contain lead pipes; or

ii)

Those that are served by a lead service line.

BOARD NOTE: Subsection (a)(3)(A) was derived from segments

of 40 CFR 141.86(a)(3) (2003) (2007). This allows the pool of

CWS tier 1 sampling sites to consist exclusively of structures

served by lead service lines.

CWS Tier 2 sampling sites. “CWS Tier 2 sampling sites” must

include the following buildings, including multiple-family

structures:

Those that contain copper pipes with lead solder installed

after 1982 or contain lead pipes; or

ii)

Those that are served by a lead service line.

BOARD NOTE: Subsection (a)(3)(B) was derived from segments

of 40 CFR 141.86(a)(4) (2003)

(2007). This allows the pool of

CWS tier 2 sampling sites to consist exclusively of structures

served by lead service lines.

CWS Tier 3 sampling sites. “CWS Tier 3 sampling sites” must

include the following single-family structures: those that contain

copper pipes with lead solder installed before 1983.

113

BOARD NOTE: Subsection (a)(3)(C) was derived from segments

of 40 CFR 141.86(a)(5) (2003) (2007).

NTNCWS Tier 1 sampling sites. “NTNCWS Tier 1 sampling

sites” must include the following buildings:

Those that contain copper pipes with lead solder installed

after 1982 or which contain lead pipes; or

ii)

Those that are served by a lead service line.

BOARD NOTE: Subsection (a)(3)(D) was derived from segments

of 40 CFR 141.86(a)(6) (2003) (2007). This allows the pool of

NTNCWS tier 1 sampling sites to consist exclusively of buildings

served by lead service lines.

Alternative NTNCWS sampling sites. “Alternative NTNCWS

sampling sites” must include the following buildings: those that

contain copper pipes with lead solder installed before 1983.

BOARD NOTE: Subsection (a)(3)(E) was derived from segments

of 40 CFR 141.86(a)(7) (2003) (2007).

Selection of sampling sites. Suppliers must select sampling sites for their

sampling pool as follows:

CWS Suppliers. CWS suppliers must use CWS tier 1 sampling

sites, except that the supplier may include CWS tier 2 or CWS tier

3 sampling sites in its sampling pool as follows:

If multiple-family residences comprise at least 20 percent

of the structures served by a supplier, the supplier may use

CWS tier 2 sampling sites in its sampling pool; or

BOARD NOTE: Subsection (a)(4)(A)(i) was derived from

a segment of 40 CFR 141.86(a)(3)(ii) (2003)

(2007).

ii)

If the CWS supplier has an insufficient number of CWS tier

1 sampling sites on its distribution system, the supplier may

use CWS tier 2 sampling sites in its sampling pool; or

BOARD NOTE: Subsection (a)(4)(A)(ii) was derived from

a segment of 40 CFR 141.86(a)(4) (2003) (2007).

iii)

If the CWS supplier has an insufficient number of CWS tier

1 and CWS tier 2 sampling sites on its distribution system,

114

the supplier may complete its sampling pool with CWS tier

3 sampling sites.

BOARD NOTE: Subsection (a)(4)(A)(iii) was derived

from a segment of 40 CFR 141.86(a)(5) (2003) (2007).

iv)

If the CWS supplier has an insufficient number of CWS tier

1 sampling sites, CWS tier 2 sampling sites, and CWS tier

3 sampling sites, the supplier must use those CWS tier 1

sampling sites, CWS tier 2 sampling sites, and CWS tier 3

sampling sites that it has and complete its sampling pool

with representative sites throughout its distribution system

for the balance of its sampling sites. For the purpose of this

subsection (a)(4)(A)(iv), a representative site is a site in

which the plumbing materials used at that site would be

commonly found at other sites served by the water system.

BOARD NOTE: Subsection (a)(4)(A)(iv) was derived

from segments of 40 CFR 141.86(a)(5) (2003) (2007).

NTNCWS suppliers.

An NTNCWS supplier must select NTNCWS tier 1

sampling sites for its sampling pool.

BOARD NOTE: Subsection (a)(4)(B)(i) was derived from

segments of 40 CFR 141.86(a)(6) (2003) (2007).

ii)

If the NTNCWS supplier has an insufficient number of

NTNCWS tier 1 sampling sites, the supplier may complete

its sampling pool with alternative NTNCWS sampling

sites.

BOARD NOTE: Subsection (a)(4)(B)(ii) was derived from

segments of 40 CFR 141.86(a)(7) (2003)

(2007).

iii)

If the NTNCWS supplier has an insufficient number of

NTNCWS tier 1 sampling sites and NTNCWS alternative

sampling sites, the supplier must use representative sites

throughout its distribution system. For the purpose of this

subsection (a)(4)(B)(ii), a representative site is a site in

which the plumbing materials used at that site would be

commonly found at other sites served by the water system.

BOARD NOTE: Subsection (a)(4)(B)(iii) was derived

from segments of 40 CFR 141.86(a)(7) (2003) (2007).

115

Suppliers with lead service lines. Any supplier whose distribution

system contains lead service lines must draw samples during each

six-month monitoring period from sampling sites as follows:

50 percent of the samples from sampling sites that contain

lead pipes or from sampling sites that have copper pipes

with lead solder; and

ii)

50 percent of those samples from sites served by a lead

service line.

iii)

A supplier that cannot identify a sufficient number of

sampling sites served by a lead service line must collect

first-draw samples from all of the sites identified as being

served by such lines.

BOARD NOTE: Subsection (a)(4)(C) was derived from segments

of 40 CFR 141.86(a)(8) (2003) (2007). This allows the pool of

sampling sites to consist exclusively of structures or buildings

served by lead service lines.

Sample collection methods.

All tap samples for lead and copper collected in accordance with this

Subpart G, with the exception of lead service line samples collected under

Section 611.354(c) and samples collected under subsection (b)(5) of this

Section, must be first-draw samples.

First-draw tap samples.

Each first-draw tap sample for lead and copper must be one liter in

volume and have stood motionless in the plumbing system of each

sampling site for at least six hours.

First-draw samples from residential housing must be collected

from the cold water kitchen tap or bathroom sink tap.

First-draw samples from a non-residential building must be one

liter in volume and must be collected at an interior tap from which

water is typically drawn for consumption.

Non-first-draw samples collected in lieu of first-draw samples

pursuant to subsection (b)(5) of this Section must be one liter in

volume and must be collected at an interior tap from which water

is typically drawn for consumption.

116

First-draw samples may be collected by the supplier or the supplier

may allow residents to collect first-draw samples after instructing

the residents of the sampling procedures specified in this

subsection (b).

To avoid problems of residents handling nitric acid,

acidification of first-draw samples may be done up to 14

days after the sample is collected.

ii)

After acidification to resolubilize the metals, the sample

must stand in the original container for the time specified in

the approved USEPA method before the sample can be

analyzed.

If a supplier allows residents to perform sampling under subsection

(b)(2)(D) of this Section, the supplier may not challenge the

accuracy of sampling results based on alleged errors in sample

collection.

Service line samples.

Each service line sample must be one liter in volume and have

stood motionless in the lead service line for at least six hours.

Lead service line samples must be collected in one of the following

three ways:

At the tap after flushing that volume of water calculated as

being between the tap and the lead service line based on the

interior diameter and length of the pipe between the tap and

the lead service line;

ii)

Tapping directly into the lead service line; or

iii)

If the sampling site is a single-family structure, allowing

the water to run until there is a significant change in

temperature that would be indicative of water that has been

standing in the lead service line.

Follow-up first-draw tap samples.

A supplier must collect each follow-up first-draw tap sample from

the same sampling site from which it collected the previous

samples.

117

If, for any reason, the supplier cannot gain entry to a sampling site

in order to collect a follow-up tap sample, the supplier may collect

the follow-up tap sample from another sampling site in its

sampling pool, as long as the new site meets the same targeting

criteria and is within reasonable proximity of the original site.

Substitute non-first-draw samples.

A NTNCWS supplier or a CWS supplier that meets the criteria of

Sections 611.355(c)(7)(A) and (c)(7)(B), that does not have

enough taps that can supply first-draw samples, as defined in

Section 611.102, may apply to the Agency in writing to substitute

non-first-draw samples by a SEP granted under Section 611.110.

A supplier approved to substitute non-first-draw samples must

collect as many first-draw samples from appropriate taps as

possible and identify sampling times and locations that would

likely result in the longest standing time for the remaining sites.

The Agency may grant a SEP that waives the requirement for prior

Agency approval of non-first-draw sample sampling sites selected

by the system.

Number of samples.

Suppliers must collect at least one sample from the number of sites listed

in the first column of Table D of this Part (labelled “standard monitoring”)

during each six-month monitoring period specified in subsection (d) of

this Section.

A supplier conducting reduced monitoring pursuant to subsection (d)(4) of

this Section must collect one sample from the number of sites specified in

the second column of Table D of this Part (labelled “reduced monitoring”)

during each reduced monitoring period specified in subsection (d)(4) of

this Section. Such reduced monitoring sites must be representative of the

sites required for standard monitoring. A supplier whose system has

fewer than five drinking water taps that can be used for human

consumption and which can meet the sampling site criteria of subsection

(a) of this Section to reach the required number of sampling sites listed in

this subsection (c), must collect multiple samples from individual taps. To

accomplish this, the supplier must collect at least one sample from each

tap, then it must collect additional samples from those same taps on

different days during the monitoring period, in order to collect a total

number of samples that meets the required number of sampling sites.

Alternatively, the Agency must, by a SEP issued pursuant to Section

611.110, allow a supplier whose system has fewer than five drinking water

118

taps to collect a number of samples that is fewer than the number of sites

specified in subsection (c) of this Section if it determines that 100 percent

of all taps that can be used for human consumption are sampled and that

the reduced number of samples will produce the same results as would the

collection of multiple samples from some taps. Any Agency approval of a

reduction of the minimum number of samples must be based on a request

from the supplier or on on-site verification by the Agency. The Agency

may, by a SEP issued pursuant to Section 611.110, specify sampling

locations when a system is conducting reduced monitoring.

Timing of monitoring.

Initial tap sampling. The first six-month monitoring period for small,

medium-sized and large system suppliers must begin on the dates

specified in Table E of this Part.

All large system suppliers must monitor during each of two

consecutive six-month periods.

All small- and medium-sized system suppliers must monitor during

each consecutive six-month monitoring period until the following

is true:

The supplier exceeds the lead action level or the copper

action level and is therefore required to implement the

corrosion control treatment requirements under Section

611.351, in which case the supplier must continue

monitoring in accordance with subsection (d)(2) of this

Section; or

ii)

The supplier meets the lead action level and the copper

action level during each of two consecutive six-month

monitoring periods, in which case the supplier may reduce

monitoring in accordance with subsection (d)(4) of this

Section.

Monitoring after installation of corrosion control and source water

treatment.

Any large system supplier that installs optimal corrosion control

treatment pursuant to Section 611.351(d)(4) must have monitored

during each of two consecutive six-month monitoring periods

before January 1, 1998.

Any small- or medium-sized system supplier that installs optimal

corrosion control treatment pursuant to Section 611.351(e)(5) must

119

monitor during each of two consecutive six-month monitoring

periods before 36 months after the Agency approves optimal

corrosion control treatment, as specified in Section 611.351(e)(6).

Any supplier that installs source water treatment pursuant to

Section 611.353(a)(3) must monitor during each of two

consecutive six-month monitoring periods before 36 months after

completion of step 2, as specified in Section 611.353(a)(4).

Monitoring after the Agency specification of water quality parameter

values for optimal corrosion control. After the Agency specifies the

values for water quality control parameters pursuant to Section 611.352(f),

the supplier must monitor during each subsequent six-month monitoring

period, with the first six-month monitoring period to begin on the date the

Agency specifies the optimal values.

Reduced monitoring.

Reduction to annual for small- and medium-sized system suppliers

meeting the lead and copper action levels. A small- or medium-

sized system supplier that meets the lead and copper action levels

during each of two consecutive six-month monitoring periods may

reduce the number of samples in accordance with subsection (c) of

this Section, and reduce the frequency of sampling to once per

year. A small- or medium-sized system supplier that collects

fewer than five samples as specified in subsection (c) of this

Section and which meets the lead and copper action levels during

each of two consecutive six-month monitoring periods may reduce

its frequency of sampling to once per year. In no case can the

supplier reduce the number of samples required below the

minimum of one sample per available tap. This reduced sampling

may only begin during the calendar year immediately following

the end of the second consecutive six-month monitoring period.

SEP allowing reduction to annual for suppliers maintaining water

quality control parameters.

Any supplier that meets the lead action level and which

maintains the range of values for the water quality control

parameters reflecting optimal corrosion control treatment

specified by the Agency under Section 611.352(f) during

each of two consecutive six-month monitoring periods may

reduce the frequency of monitoring to once per year and

the number of lead and copper samples to that specified by

subsection (c) of this Section if it receives written approval

from the Agency in the form of a SEP granted pursuant to

120

Section 611.110. This reduced sampling may only begin

during the calendar year immediately following the end of

the second consecutive six-month monitoring period.

ii)

The Agency must review monitoring, treatment, and other

relevant information submitted by the water system in

accordance with Section 611.360, and must notify the

system in writing by a SEP granted pursuant to Sections

611.110 when it determines the system is eligible to reduce

its monitoring frequency to once every three years pursuant

to this subsection (d)(4).

iii)

The Agency must review, and where appropriate, revise its

determination under subsection (d)(4)(B)(i) of this Section

when the supplier submits new monitoring or treatment

data, or when other data relevant to the number and

frequency of tap sampling becomes available to the

Agency.

Reduction to triennial for small- and medium-sized system

suppliers.

Small- and medium-sized system suppliers meeting lead

and copper action levels. A small- or medium-sized system

supplier that meets the lead action level and which meets

the lead and copper action levels during three consecutive

years of monitoring may reduce the frequency of

monitoring for lead and copper from annually to once every

three years.

ii)

SEP for suppliers meeting optimal corrosion control

treatment. Any supplier that maintains the range of values

for the water quality control parameters reflecting optimal

corrosion control treatment specified by the Agency under

Section 611.352(f) during three consecutive years of

monitoring may reduce its monitoring frequency from

annual to once every three years if it receives written

approval from the Agency in the form of a SEP granted

pursuant to Section 611.110. Samples collected once every

three years must be collected no later than every third

calendar year.

iii)

The Agency must review, and where appropriate, revise its

determination under subsection (d)(4)(C)(ii) of this Section

when the supplier submits new monitoring or treatment

data, or when other data relevant to the number and

121

frequency of tap sampling becomes available to the

Agency.

Sampling at a reduced frequency. A supplier that reduces the

number and frequency of sampling must collect these samples

from representative sites included in the pool of targeted sampling

sites identified in subsection (a) of this Section, preferentially

selecting those sampling sites from the highest tier first. Suppliers

sampling annually or less frequently must conduct the lead and

copper tap sampling during the months of June, July, August, or

September, unless the Agency has approved a different sampling

period in accordance with subsection (d)(4)(D)(i) of this Section.

The Agency may grant a SEP pursuant to Section 611.110

that approves a different period for conducting the lead and

copper tap sampling for systems collecting a reduced

number of samples. Such a period must be no longer than

four consecutive months and must represent a time of

normal operation where the highest levels of lead are most

likely to occur. For a NTNCWS supplier that does not

operate during the months of June through September and

for which the period of normal operation where the highest

levels of lead are most likely to occur is not known, the

Agency must designate a period that represents a time of

normal operation for the system. This reduced sampling

may only begin during the period approved or designated

by the Agency in the calendar year immediately following

the end of the second consecutive six-month monitoring

period for systems initiating annual monitoring and during

the three-year period following the end of the third

consecutive calendar year of annual monitoring for a

supplier initiating triennial monitoring.

ii)

A supplier monitoring annually that has been collecting

samples during the months of June through September and

which receives Agency approval to alter its sample

collection period under subsection (d)(4)(D)(i) of this

Section must collect its next round of samples during a

time period that ends no later than 21 months after the

previous round of sampling. A supplier monitoring once

every three years that has been collecting samples during

the months of June through September and which receives

Agency approval to alter the sampling collection period as

provided in subsection (d)(4)(D)(i) of this Section must

collect its next round of samples during a time period that

ends no later than 45 months after the previous round of

122

sampling. Subsequent rounds of sampling must be

collected annually or once every three years, as required by

this Section. A small system supplier with a waiver

granted pursuant to subsection (g) of this Section that has

been collecting samples during the months of June through

September and which receives Agency approval to alter its

sample collection period under subsection (d)(4)(D)(i) of

this Section must collect its next round of samples before

the end of the nine-year compliance cycle (as that term is

defined in Section 611.101).

Any water system that demonstrates for two consecutive six-month

monitoring periods that the tap water lead level computed under

Section 611.350(c)(3) is less than or equal to 0.005 mg/ℓ and that

the tap water copper level computed under Section 611.350(c)(3)

is less than or equal to 0.65 mg/ℓ may reduce the number of

samples in accordance with subsection (c) of this Section and

reduce the frequency of sampling to once every three calendar

years.

Resumption of standard monitoring.

Small- or medium-sized suppliers exceeding lead or copper

action level. A small- or medium-sized system supplier

subject to reduced monitoring that exceeds the lead action

level or the copper action level must resume sampling in

accordance subsection (d)(3) of this Section and collect the

number of samples specified for standard monitoring under

subsection (c) of this Section. Such a supplier must also

conduct water quality parameter monitoring in accordance

with Section 611.357 (b), (c), or (d) (as appropriate) during

the six-month monitoring period in which it exceeded the

action level. Any such supplier may resume annual

monitoring for lead and copper at the tap at the reduced

number of sites specified in subsection (c) of this Section

after it has completed two subsequent consecutive six-

month rounds of monitoring that meet the criteria of

subsection (d)(4)(A) of this Section. Any such supplier

may resume monitoring once every three years for lead and

copper at the reduced number of sites after it demonstrates

through subsequent rounds of monitoring that it meets the

criteria of either subsection (d)(4)(C) or (d)(4)(E) of this

Section.

ii)

Suppliers failing to operate within water quality control

parameters. Any supplier subject to reduced monitoring

123

frequency that fails to meet the lead action level during any

four-month monitoring period or that fails to operate within

the range of values for the water quality control parameters

specified pursuant to Section 611.352(f) for more than nine

days in any six-month period specified in Section

611.357(d) must conduct tap water sampling for lead and

copper at the frequency specified in subsection (d)(3) of

this Section, must collect the number of samples specified

for standard monitoring under subsection (c) of this

Section, and must resume monitoring for water quality

parameters within the distribution system in accordance

with Section 611.357(d). This standard tap water sampling

must begin no later than the six-month period beginning

January 1 of the calendar year following the lead action

level exceedance or water quality parameter excursion. A

supplier may resume reduced monitoring for lead and

copper at the tap and for water quality parameters within

the distribution system only if it fulfills the conditions set

forth in subsection (d)(4)(H) of this Section.

BOARD NOTE: The Board moved the material from the last

sentence of 40 CFR 141.86(d)(4)(vi)(B) and 40 CFR

141.86(d)(4)(vi)(B)(

) through (d)(4)(vi)(B)(

) (2007) to

subsections (d)(4)(H) and (d)(4)(H)(i) through (d)(4)(H)(iii), since

Illinois Administrative Code codification requirements allow

subsections only to four indent levels.

Any water supplier subject to a reduced monitoring frequency

under subsection (d)(4) of this Section that either adds a new

source of water or changes any water treatment must inform notify

the Agency in writing in accordance with Section 611.360(a)(3) of

any upcoming long-term change in treatment or addition of a new

source as described in that Section. The Agency must review and

approve the addition of a new source or long-term change in water

treatment before it is implemented by the supplier. The Agency

may, by a SEP granted pursuant to Section 611.110, require the

system to resume sampling in accordance with subsection (d)(3) of

this Section and collect the number of samples specified for

standard monitoring under subsection (c) of this Section or take

other appropriate steps such as increased water quality parameter

monitoring or re-evaluation of its corrosion control treatment given

the potentially different water quality considerations.

A supplier required under subsection (d)(4)(F) of this Section to

resume monitoring in accordance with Section 611.357(d) may

resume reduced monitoring for lead and copper at the tap and for

124

water quality parameters within the distribution system under the

following conditions:

The supplier may resume annual monitoring for lead and

copper at the tap at the reduced number of sites specified in

subsection (c) of this Section after it has completed two

subsequent six-month rounds of monitoring that meet the

criteria of subsection (d)(4)(B) of this Section and the

supplier has received written approval from the Agency by

a SEP pursuant to Section 611.110 that it is appropriate to

resume reduced monitoring on an annual frequency. This

sampling must begin during the calendar year immediately

following the end of the second consecutive six-month

monitoring period.

ii)

The supplier may resume monitoring for lead and copper

once every three years at the tap at the reduced number of

sites after it demonstrates through subsequent rounds of

monitoring that it meets the criteria of either subsection

(d)(4)(C) or (d)(4)(E) of this Section and the system has

received a SEP under Section 611.110 from the Agency

that it is appropriate to resume monitoring once every three

years.

iii)

The supplier may reduce the number of water quality

parameter tap water samples required in accordance with

Section 611.357(e)(1) and the frequency with which it

collects such samples in accordance with Section

611.357(e)(2). Such a system may not resume monitoring

once every three years for water quality parameters at the

tap until it demonstrates, in accordance with the

requirements of Section 611.357(e)(2), that it has re-

qualified for monitoring once every three years.

BOARD NOTE: Subsections (d)(4)(H) and

(d)(4)(H)(i) through

(d)(4)(H)(iii) are derived from the last sentence of 40 CFR

141.86(d)(4)(vi)(B) and 40 CFR 141.86(d)(4)(vi)(B)(

) through

(d)(4)(vi)(B)(

) (2003)

(2007), since Illinois Administrative Code

codification requirements allow only four indent levels of

subsections.

Additional monitoring. The results of any monitoring conducted in addition to

the minimum requirements of this Section must be considered by the supplier and

the Agency in making any determinations (i.e., calculating the 90th percentile

lead action level or the copper level) under this Subpart G.

125

Invalidation of lead or copper tap water samples. A sample invalidated under this

subsection does not count toward determining lead or copper 90th percentile

levels under Section 611.350(c)(3) or toward meeting the minimum monitoring

requirements of subsection (c) of this Section.

The Agency must invalidate a lead or copper tap water sample if it

determines that one of the following conditions exists:

The laboratory establishes that improper sample analysis caused

erroneous results;

The sample was taken from a site that did not meet the site

selection criteria of this Section;

The sample container was damaged in transit; or

There is substantial reason to believe that the sample was subject

to tampering.

The supplier must report the results of all samples to the Agency and all

supporting documentation for samples the supplier believes should be

invalidated.

To invalidate a sample under subsection (f)(1) of this Section, the decision

and the rationale for the decision must be documented in writing. The

Agency may not invalidate a sample solely on the grounds that a follow-

up sample result is higher or lower than that of the original sample.

The water supplier must collect replacement samples for any samples

invalidated under this Section if, after the invalidation of one or more

samples, the supplier has too few samples to meet the minimum

requirements of subsection (c) of this Section. Any such replacement

samples must be taken as soon as possible, but no later than 20 days after

the date the Agency invalidates the sample or by the end of the applicable

monitoring period, whichever occurs later. Replacement samples taken

after the end of the applicable monitoring period must not also be used to

meet the monitoring requirements of a subsequent monitoring period. The

replacement samples must be taken at the same locations as the

invalidated samples or, if that is not possible, at locations other than those

already used for sampling during the monitoring period.

Monitoring waivers for small system suppliers. Any small system supplier that

meets the criteria of this subsection (g) may apply to the Agency to reduce the

frequency of monitoring for lead and copper under this Section to once every nine

years (i.e., a “full waiver”) if it meets all of the materials criteria specified in

subsection (g)(1) of this Section and all of the monitoring criteria specified in

126

subsection (g)(2) of this Section. Any small system supplier that meets the

criteria in subsections (g)(1) and (g)(2) of this Section only for lead, or only for

copper, may apply to the State for a waiver to reduce the frequency of tap water

monitoring to once every nine years for that contaminant only (i.e., a “partial

waiver”).

Materials criteria. The supplier must demonstrate that its distribution

system and service lines and all drinking water supply plumbing,

including plumbing conveying drinking water within all residences and

buildings connected to the system, are free of lead-containing materials or

copper-containing materials, as those terms are defined in this subsection

(g)(1), as follows:

Lead. To qualify for a full waiver, or a waiver of the tap water

monitoring requirements for lead (i.e., a “lead waiver”), the water

supplier must provide certification and supporting documentation

to the Agency that the system is free of all lead-containing

materials, as follows:

It contains no plastic pipes that contain lead plasticizers, or

plastic service lines that contain lead plasticizers; and

ii)

It is free of lead service lines, lead pipes, lead soldered pipe

joints, and leaded brass or bronze alloy fittings and

fixtures, unless such fittings and fixtures meet the

specifications of NSF Standard 61, section 9, incorporated by

reference in Section 611.102.

BOARD NOTE: Corresponding 40 CFR 141.86(g)(1)(i)(B)

specifies “any standard established pursuant to 42 USC

300g-6(e) (SDWA section 1417(e)).” USEPA has stated

that the NSF standard is that standard. See 62 Fed. Reg.

44684 (Aug. 22, 1997).

Copper. To qualify for a full waiver, or a waiver of the tap water

monitoring requirements for copper (i.e., a “copper waiver”), the

water supplier must provide certification and supporting

documentation to the Agency that the system contains no copper

pipes or copper service lines.

Monitoring criteria for waiver issuance. The supplier must have completed

at least one six-month round of standard tap water monitoring for lead and

copper at sites approved by the Agency and from the number of sites

required by subsection (c) of this Section and demonstrate that the 90th

percentile levels for any and all rounds of monitoring conducted since the

system became free of all lead-containing or copper-containing materials,

127

as appropriate, meet the following criteria:

Lead levels. To qualify for a full waiver, or a lead waiver, the

supplier must demonstrate that the 90th percentile lead level does

not exceed 0.005 mg/ℓ.

Copper levels. To qualify for a full waiver, or a copper waiver, the

supplier must demonstrate that the 90th percentile copper level

does not exceed 0.65 mg/ℓ.

State approval of waiver application. The Agency must notify the supplier

of its waiver determination by a SEP issued pursuant to Section 611.110,

in writing, setting forth the basis of its decision and any condition of the

waiver. As a condition of the waiver, the Agency may require the supplier

to perform specific activities (e.g., limited monitoring, periodic outreach

to customers to remind them to avoid installation of materials that might

void the waiver) to avoid the risk of lead or copper concentration of

concern in tap water. The small system supplier must continue monitoring

for lead and copper at the tap as required by subsections (d)(1) through

(d)(4) of this Section, as appropriate, until it receives written notification

from the Agency that the waiver has been approved.

Monitoring frequency for suppliers with waivers.

A supplier with a full waiver must conduct tap water monitoring

for lead and copper in accordance with subsection (d)(4)(D) of this

Section at the reduced number of sampling sites identified in

subsection (c) of this Section at least once every nine years and

provide the materials certification specified in subsection (g)(1) of

this Section for both lead and copper to the Agency along with the

monitoring results. Samples collected every nine years must be

collected no later than every ninth calendar year.

A supplier with a partial waiver must conduct tap water monitoring

for the waived contaminant in accordance with subsection

(d)(4)(D) of this Section at the reduced number of sampling sites

specified in subsection (c) of this Section at least once every nine

years and provide the materials certification specified in subsection

(g)(1) of this Section pertaining to the waived contaminant along

with the monitoring results. Such a supplier also must continue to

monitor for the non-waived contaminant in accordance with

requirements of subsections (d)(1) through (d)(4) of this Section,

as appropriate.

If a

Any supplier with a full or partial waiver adds a new source of

water or changes any water treatment, the supplier must notify the

128

Agency in writing in accordance with Section 611.360(a)(3) of any

upcoming long-term change in treatment or addition of a new

source, as described in that section. The Agency must review and

approve the addition of a new source or long-term change in water

treatment before it is implemented by the supplier. The Agency

has the authority to require the supplier to add or modify waiver

conditions (e.g., require recertification that the supplier’s system is

free of lead-containing or copper-containing materials, require

additional rounds of monitoring), if it deems such modifications

are necessary to address treatment or source water changes at the

system.

If a supplier with a full or partial waiver becomes aware that it is

no longer free of lead-containing or copper-containing materials,

as appropriate (e.g., as a result of new construction or repairs), the

supplier must notify the Agency in writing no later than 60 days

after becoming aware of such a change.

Continued eligibility. If the supplier continues to satisfy the requirements

of subsection (g)(4) of this Section, the waiver will be renewed

automatically, unless any of the conditions listed in subsection (g)(5)(A)

through (g)(5)(C) of this Section occur. A supplier whose waiver has

been revoked may re-apply for a waiver at such time as it again meets the

appropriate materials and monitoring criteria of subsections (g)(1) and

(g)(2) of this Section.

A supplier with a full waiver or a lead waiver no longer satisfies

the materials criteria of subsection (g)(1)(A) of this Section or has

a 90th percentile lead level greater than 0.005 mg/ℓ.

A supplier with a full waiver or a copper waiver no longer satisfies

the materials criteria of subsection (g)(1)(B) of this Section or has

a 90th percentile copper level greater than 0.65 mg/ℓ.

The State notifies the supplier, in writing, that the waiver has been

revoked, setting forth the basis of its decision.

Requirements following waiver revocation. A supplier whose full or

partial waiver has been revoked by the Agency is subject to the corrosion

control treatment and lead and copper tap water monitoring requirements,

as follows:

If the supplier exceeds the lead or copper action level, the supplier

must implement corrosion control treatment in accordance with the

deadlines specified in Section 611.351(e), and any other applicable

requirements of this Subpart G.

129

If the supplier meets both the lead and the copper action level, the

supplier must monitor for lead and copper at the tap no less

frequently than once every three years using the reduced number

of sample sampling sites specified in subsection (c) of this Section.

Pre-existing waivers. Small system supplier waivers approved by the

Agency in writing prior to April 11, 2000 must remain in effect under the

following conditions:

If the supplier has demonstrated that it is both free of lead-

containing and copper-containing materials, as required by

subsection (g)(1) of this Section and that its 90th percentile lead

levels and 90th percentile copper levels meet the criteria of

subsection (g)(2) of this Section, the waiver remains in effect so

long as the supplier continues to meet the waiver eligibility criteria

of subsection (g)(5) of this Section. The first round of tap water

monitoring conducted pursuant to subsection (g)(4) of this Section

must be completed no later than nine years after the last time the

supplier monitored for lead and copper at the tap.

If the supplier has met the materials criteria of subsection (g)(1) of

this Section but has not met the monitoring criteria of subsection

(g)(2) of this Section, the supplier must conduct a round of

monitoring for lead and copper at the tap demonstrating that it met

the criteria of subsection (g)(2) of this Section no later than

September 30, 2000. Thereafter, the waiver must remain in effect

as long as the supplier meets the continued eligibility criteria of

subsection (g)(5) of this Section. The first round of tap water

monitoring conducted pursuant to subsection (g)(4) of this Section

must be completed no later than nine years after the round of

monitoring conducted pursuant to subsection (g)(2) of this Section.

Section 611.357

Monitoring for Water Quality Parameters

All large system suppliers, and all small- and medium-sized system suppliers that exceed the

lead action level or the copper action level, must monitor water quality parameters in addition to

lead and copper in accordance with this Section. The requirements of this Section are

summarized in Table G of this Part.

General Requirements.

130

Sample collection methods.

Use of tap samples. The totality of all tap samples collected by a

supplier must be representative of water quality throughout the

distribution system taking into account the number of persons

served, the different sources of water, the different treatment

methods employed by the supplier, and seasonal variability.

Although a supplier may conveniently conduct tap sampling for

water quality parameters at sites used for coliform sampling

performed pursuant to Subpart L of this Part, it is not required to

do so, and a supplier is not required to perform tap sampling

pursuant to this Section at taps targeted for lead and copper

sampling under Section 611.356(a).

Use of entry point samples. Each supplier must collect samples at

entry points to the distribution system from locations

representative of each source after treatment. If a supplier draws

water from more than one source and the sources are combined

before distribution, the supplier must sample at an entry point to

the distribution system during periods of normal operating

conditions (i.e., when water is representative of all sources being

used).

Number of samples.

Tap samples. Each supplier must collect two tap samples for

applicable water quality parameters during each six-month

monitoring period specified under subsections (b) through (e) of

this Section from the number of sites indicated in the first column

of Table E of this Part.

Entry point samples.

Initial monitoring. Except as provided in subsection (c)(3)

of this Section, each supplier must collect two samples for

each applicable water quality parameter at each entry point

to the distribution system during each six-month

monitoring period specified in subsection (b) of this

Section.

ii)

Subsequent monitoring. Each supplier must collect one

sample for each applicable water quality parameter at each

entry point to the distribution system during each six-

month monitoring period specified in subsections (c)

through (e) of this Section.

131

Initial Sampling.

Large systems. Each large system supplier must measure the applicable

water quality parameters specified in subsection (b)(3) of this Section at

taps and at each entry point to the distribution system during each six-

month monitoring period specified in Section 611.356(d)(1).

Small- and medium-sized systems. Each small- and medium-sized system

supplier must measure the applicable water quality parameters specified in

subsection (b)(3) of this Section at the locations specified in this

subsection during each six-month monitoring period specified in Section

611.356(d)(1) during which the supplier exceeds the lead action level or

the copper action level.

Water quality parameters.

pH;

Alkalinity;

Orthophosphate, when an inhibitor containing a phosphate

compound is used;

Silica, when an inhibitor containing a silicate compound is used;

Calcium;

Conductivity; and

Water temperature.

Monitoring after installation of corrosion control.

Large systems. Each large system supplier that installs optimal corrosion

control treatment pursuant to Section 611.351(d)(4) must measure the

water quality parameters at the locations and frequencies specified in

subsections (c)(4) and (c)(5) of this Section during each six-month

monitoring period specified in Section 611.356(d)(2)(A).

Small- and medium-sized systems. Each small- or medium-sized system

that installs optimal corrosion control treatment pursuant to Section

611.351(e)(5) must measure the water quality parameters at the locations

and frequencies specified in subsections (c)(4) and (c)(5) of this Section

during each six-month monitoring period specified in Section

611.356(d)(2)(B) in which the supplier exceeds the lead action level or the

copper action level.

132

Any groundwater system can limit entry point sampling described in

subsection (c)(2) of this Section to those entry points that are

representative of water quality and treatment conditions throughout the

system. If water from untreated groundwater sources mixes with water

from treated groundwater sources, the system must monitor for water

quality parameters both at representative entry points receiving treatment

and representative entry points receiving no treatment. Prior to the start of

any monitoring under this subsection, the system must provide to the

Agency written information identifying the selected entry points and

documentation, including information on seasonal variability, sufficient to

demonstrate that the sites are representative of water quality and treatment

conditions throughout the system.

Tap water samples, two samples at each tap for each of the following

water quality parameters:

pH;

Alkalinity;

Orthophosphate, when an inhibitor containing a phosphate

compound is used;

Silica, when an inhibitor containing a silicate compound is used;

and

Calcium, when calcium carbonate stabilization is used as part of

corrosion control.

Entry point samples, except as provided in subsection (c)(3) of this

Section, one sample at each entry point to the distribution system every

two weeks (bi-weekly) for each of the following water quality parameters:

pH;

When alkalinity is adjusted as part of optimal corrosion control, a

reading of the dosage rate of the chemical used to adjust alkalinity,

and the alkalinity concentration; and

When a corrosion inhibitor is used as part of optimal corrosion

control, a reading of the dosage rate of the inhibitor used, and the

concentration of orthophosphate or silica (whichever is

applicable).

Monitoring after the Agency specifies water quality parameter values for optimal

133

corrosion control.

Large system suppliers. After the Agency has specified the values for

applicable water quality control parameters reflecting optimal corrosion

control treatment pursuant to Section 611.352(f), each large system

supplier must measure the applicable water quality parameters in

accordance with subsection (c) of this Section and determine compliance

with the requirements of Section 611.352(g) every six months with the

first six-month period to begin on the date either January 1 or July 1,

whichever comes first, after the State Agency specifies the optimal values

under Section 611.352(f).

Small- and medium-sized system suppliers. Each small- or medium-sized

system supplier must conduct such monitoring during each six-month

monitoring period specified in this subsection (d) in which the supplier

exceeds the lead action level or the copper action level. For any such

small and medium-size system that is subject to a reduced monitoring

frequency pursuant to Section 611.356(d)(4) at the time of the action level

exceedence, the end start of the applicable six-month monitoring period

under this subsection must coincide with the end start of the applicable

monitoring period under Section 611.356(d)(4).

Compliance with Agency-designated optimal water quality parameter

values must be determined as specified under Section 611.352(g).

Reduced monitoring.

Reduction in tap monitoring. A supplier that has maintained the range of

values for the water quality parameters reflecting optimal corrosion

control treatment during each of two consecutive six-month monitoring

periods under subsection (d) of this Section must continue monitoring at

the entry points to the distribution system as specified in subsection (c)(4)

of this Section. Such a supplier may collect two samples from each tap for

applicable water quality parameters from the reduced number of sites

indicated in the second column of Table E of this Part during each

subsequent six-month monitoring period.

Reduction in monitoring frequency.

Staged reductions in monitoring frequency.

Annual monitoring. A supplier that maintains the range of

values for the water quality parameters reflecting optimal

corrosion control treatment specified pursuant to Section

611.352(f) during three consecutive years of monitoring

may reduce the frequency with which it collects the number

134

of tap samples for applicable water quality parameters

specified in subsection (e)(1) of this Section from every six

months to annually. This reduced sampling may only

begin during the calendar year immediately following the

end of the monitoring period in which the third consecutive

year of six-month monitoring occurs.

ii)

Triennial monitoring. A supplier that maintains the range

of values for the water quality parameters reflecting

optimal corrosion control treatment specified pursuant to

Section 611.352(f), during three consecutive years of

annual monitoring under subsection (e)(2)(A)(i) of this

Section may reduce the frequency with which it collects the

number of tap samples for applicable water quality

parameters specified in subsection (e)(1) of this Section

from annually to once every three years. This reduced

sampling may only begin no later than the third calendar

year following the end of the monitoring period in which

the third consecutive year of monitoring occurs.

A water supplier may reduce the frequency with which it collects

tap samples for applicable water quality parameters specified in

subsection (e)(1) of this Section to every three years if it

demonstrates the following that it has fulfilled the conditions set

forth in subsections (g)(4)(C)(i) through (g)(4)(C)(iii) of this

Section during two consecutive monitoring periods:, subject to the

conditions of subsection (g)(4)(C)(iii) of this Section.

That its tap water lead level at the 90th percentile is less

than or equal to the PQL for lead specified in Section

611.359(a)(1)(B);

ii)

That its tap water copper level at the 90th percentile is less

than or equal to 0.65 mg/ℓ for copper in Section

611.350(c)(2); and

iii)

That it also has maintained the range of values for the water

quality parameters reflecting optimal corrosion control

treatment specified by the Agency under Section

611.352(f).

iv)

Monitoring conducted every three years must be done no

later than every third calendar year.

A supplier that conducts sampling annually or every three years must

collect these samples evenly throughout the calendar year so as to reflect

135

seasonal variability.

Any supplier subject to a reduced monitoring frequency pursuant to this

Section 611.358

Monitoring for Lead and Copper in Source Water

Sample location, collection methods, and number of samples.

A supplier that fails to meet the lead action level or the copper action level

on the basis of tap samples collected in accordance with Section 611.356

must collect lead and copper source water samples in accordance with the

following requirements regarding sample location, number of samples,

and collection methods:

A groundwater supplier must take a minimum of one sample at

every entry point to the distribution system that is representative of

each well after treatment (hereafter called a sampling point). The

supplier must take one sample at the same sampling point unless

conditions make another sampling point more representative of

each source or treatment plant.

A surface water supplier must take a minimum of one sample at

every entry point to the distribution system after any application of

136

treatment or in the distribution system at a point that is

representative of each source after treatment (hereafter called a

sampling point). The system must take each sample at the same

sampling point unless conditions make another sampling point

more representative of each source or treatment plant.

BOARD NOTE: For the purposes of this subsection (a)(1)(B),

surface water systems include systems with a combination of

surface and ground sources.

If a supplier draws water from more than one source and the

sources are combined before distribution, the supplier must sample

at an entry point to the distribution system during periods of

normal operating conditions (i.e., when water is representative of

all sources being used).

The Agency may, by a SEP issued pursuant to Section 611.110,

reduce the total number of samples that must be analyzed by

allowing the use of compositing. Compositing of samples must be

done by certified laboratory personnel. Composite samples from a

maximum of five samples are allowed, provided that if the lead

concentration in the composite sample is greater than or equal to

0.001 mg/ℓ or the copper concentration is greater than or equal to

0.160 mg/ℓ, then the supplier must do either of the following:

The supplier must take and analyze a follow-up sample

within 14 days at each sampling point included in the

composite; or

ii)

If duplicates of or sufficient quantities from the original

samples from each sampling point used in the composite

are available, the supplier may use these instead of

resampling.

SEP requiring an additional sample.

When the Agency determines that the results of sampling indicate

an exceedence of the lead or copper MPC established under

Section 611.353(b)(4), it must, by a SEP issued pursuant to Section

611.110, require the supplier to collect one additional sample as

soon as possible after the initial sample at the same sampling point,

but no later than two weeks after the supplier took the initial

sample.

If a supplier takes an Agency-required confirmation sample for

lead or copper, the supplier must average the results obtained from

137

the initial sample with the results obtained from the confirmation

sample in determining compliance with the Agency-specified lead

and copper MPCs.

Any analytical result below the MDL must be considered

as zero for the purposes of averaging.

ii)

Any value above the MDL but below the PQL must either

be considered as the measured value or be considered one-

half the PQL.

Monitoring frequency after system exceeds tap water action level. A supplier that

exceeds the lead action level or the copper action level in tap sampling must

collect one source water sample from each entry point to the distribution system

within no later than six months after the exceedence. end of the monitoring period

during which the lead or copper action level was exceeded. For monitoring

periods that are annual or less frequent, the end of the monitoring period is

September 30 of the calendar year in which the sampling occurs, or if the Agency

has established an alternate monitoring period by a SEP issued pursuant to

Section 611.110, the last day of that period.

Monitoring frequency after installation of source water treatment. A supplier that

installs source water treatment pursuant to Section 611.353(a)(3) must collect an

additional source water sample from each entry point to the distribution system

during each of two consecutive six-month monitoring periods on or before 36

months after completion of step 2, as specified in Section 611.353(a)(4).

Monitoring frequency after the Agency has specified the lead and copper MPCs

or has determined that source water treatment is not needed.

A supplier must monitor at the frequency specified by subsection

(d)(1)(A) or (d)(1)(B) of this Section where the Agency has specified the

MPCs pursuant to Section 611.353(b)(4) or has determined that the

supplier is not required to install source water treatment pursuant to

Section 611.353(b)(2).

GWS suppliers.

A GWS supplier required to sample by subsection (d)(1) of

this Section must collect samples once during the three-

year compliance period (as that term is defined in Section

611.101) during which the Agency makes its determination

pursuant to Section 611.353(b)(4) or 611.353(b)(2).

ii)

A GWS supplier required to sample by subsection (d)(1) of

this Section must collect samples once during each

138

subsequent compliance period.

iii)

Triennial samples must be collected every third calendar

year.

A SWS or mixed system supplier must collect samples annually

once during each calendar year, the first annual monitoring period

to begin on the date on during the year in which the Agency makes

its determination pursuant to Section 611.353(b)(4) or

611.353(b)(2).

A supplier is not required to conduct source water sampling for lead or

copper if the supplier meets the action level for the specific contaminant in

all tap water samples collected during the entire source water sampling

period applicable under subsection (d)(1)(A) or (d)(1)(B) of this Section.

Reduced monitoring frequency.

A GWS supplier may reduce the monitoring frequency for lead and copper

in source water to once during each nine-year compliance cycle (as that

term is defined in Section 611.101), provided that the samples are

collected no later than every ninth calendar year, and only if the supplier

meets one of the following criteria:

The supplier demonstrates that finished drinking water entering the

distribution system has been maintained below the maximum

permissible lead and copper concentrations specified by the State

in Section 611.353(b)(4) during at least three consecutive

compliance periods under subsection (d)(1) of this Section; or

The Agency has determined, by a SEP issued pursuant to Section

611.110, that source water treatment is not needed and the system

demonstrates that, during at least three consecutive compliance

periods in which sampling was conducted under subsection (d)(1)

of this Section, the concentration of lead in source water was less

than or equal to 0.005 mg/ℓ and the concentration of copper in

source water was less than or equal to 0.65 mg/ℓ.

A SWS or mixed system supplier may reduce the monitoring frequency in

subsection (d)(1) of this Section to once during each nine-year compliance

cycle (as that term is defined in Section 611.101),

provided that the

samples are collected no later than every ninth calendar year, and only if

the supplier meets one of the following criteria:

The supplier demonstrates that finished drinking water entering the

distribution system has been maintained below the maximum

139

permissible lead and copper concentrations specified by the

Agency under Section 611.353(b)(4) for at least three consecutive

years; or

The Agency has determined, by a SEP issued pursuant to Section

611.110, that source water treatment is not needed and the supplier

demonstrates that, during at least three consecutive years, the

concentration of lead in source water was less than or equal to

0.005 mg/ℓ and the concentration of copper in source water was

less than or equal to 0.65 mg/ℓ.

A supplier that uses a new source of water is not eligible for reduced

monitoring for lead or copper until it demonstrates by samples collected

from the new source during three consecutive monitoring periods, of the

appropriate duration provided by subsection (d)(1) of this Section, that

lead or copper concentrations are below the MPC as specified by the

Agency pursuant to Section 611.353(a)(4).

SUBPART L: MICROBIOLOGICAL MONITORING AND ANALYTICAL

REQUIREMENTS

Section 611.526

Analytical Methodology

The standard sample volume required for total coliform analysis, regardless of

analytical method used, is 100 mℓ.

Suppliers need only determine the presence or absence of total coliforms; a

determination of total coliform density is not required.

Suppliers must conduct total coliform analyses in accordance with one of the

following analytical methods, incorporated by reference in Section 611.102 (the

time from sample collection to initiation of analysis may not exceed 30 hours, and

the supplier is encouraged but not required to hold samples below 10° C during

transit):

Total Coliform Fermentation Technique, as set forth in Standard Methods,

18th, 19th, or 20th, or 21st ed.: Methods 9221 A and B, as follows:

Lactose broth, as commercially available, may be used in lieu of

lauryl tryptose broth if the supplier conducts at least 25 parallel

tests between this medium and lauryl tryptose broth using the

water normally tested and this comparison demonstrates that the

false-positive rate and false-negative rate for total coliforms, using

lactose broth, is less than 10 percent;

If inverted tubes are used to detect gas production, the media

should cover these tubes at least one-half to two-thirds after the

sample is added; and

No requirement exists to run the completed phase on 10 percent of

all total coliform-positive confirmed tubes.

Total Coliform Membrane Filter Technique, as set forth in Standard

Methods, 18th, 19th, or 20th, or 21st ed.: Methods 9222 A, B, and C.

Presence-Absence (P-A) Coliform Test, as set forth in: Standard

Methods, 18th, 19th, or

20th, or 21st ed.: Method 9221 D, as follows:

No requirement exists to run the completed phase on 10 percent of

all total coliform-positive confirmed tubes; and

159

Six-times formulation strength may be used if the medium is filter-

sterilized rather than autoclaved.

ONPG-MUG test: Standard Methods, 18th, 19th, or 20th, or 21st ed., or

from Standard Methods Online: Method 9223. (The ONPG-MUG test is

also known as the Autoanalysis Colilert System).

Colisure Test (Autoanalysis Colilert System). (The Colisure Test may be

read after an incubation time of 24 hours.)

BOARD NOTE: USEPA included the P-A Coliform and Colisure Tests

for testing finished water under the coliform rule, but did not include them

for the purposes of the surface water treatment rule, under Section

611.531, for which quantitation of total coliforms is necessary. For these

reasons, USEPA included Standard Methods: Method 9221 C for the

surface water treatment rule, but did not include it for the purposes of the

total coliform rule, under this Section.

BOARD NOTE: On March 12, 2007 (at 72 Fed. Reg. 11200), USEPA amended

note 1 to the table at corresponding 40 CFR 141.21(f)(3) to allow the use of

Standard Methods Online (at www.standardmethods.org), Method 9221 A, B, and

D (as approved in 1999) or Method 9222 A, B, and C (as approved in 1997); and

9223 B (as approved in 1997). The Board has cited to the 21st edition of

Standard Methods for the Examination of Water and Wastewater (the printed

version of Standard Methods) for Methods 9221 and 9223, since the cited

versions of the methods appears in that reference. USEPA later added Method

9221 A, B, and D; Method 9222 A, B, and C; Method 9223 from the 21st edition

of Standard Methods as an approved alternative method in Appendix A to Subpart

C, added on June 3, 2008 (at 73 Fed. Reg. 31616).

This subsection corresponds with 40 CFR 141.21(f)(4), which USEPA has

marked “reserved.” This statement maintains structural consistency with the

federal regulations.

Suppliers must conduct fecal coliform analysis in accordance with the following

160

procedure:

When the MTF Technique or P-A Coliform Test is used to test for total

coliforms, shake the lactose-positive presumptive tube or P-A vigorously

and transfer the growth with a sterile 3-mm loop or sterile applicator stick

into brilliant green lactose bile broth and EC medium, defined below, to

determine the presence of total and fecal coliforms, respectively.

For approved methods that use a membrane filter, transfer the total

coliform-positive culture by one of the following methods: remove the

membrane containing the total coliform colonies from the substrate with

sterile forceps and carefully curl and insert the membrane into a tube of

EC medium; (the laboratory may first remove a small portion of selected

colonies for verification); swab the entire membrane filter surface with a

sterile cotton swab and transfer the inoculum to EC medium (do not leave

the cotton swab in the EC medium); or inoculate individual total coliform-

positive colonies into EC medium. Gently shake the inoculated tubes of

EC medium to insure adequate mixing and incubate in a waterbath at

44.5±0.2° C for 24±2 hours. Gas production of any amount in the inner

fermentation tube of the EC medium indicates a positive fecal coliform

test.

EC medium is described in Standard Methods, 18th ed., 19th ed., and 20th

ed.: Method 9221 E.

Suppliers need only determine the presence or absence of fecal coliforms;

a determination of fecal coliform density is not required.

Suppliers must conduct analysis of E. coli in accordance with one of the

following analytical methods, incorporated by reference in Section 611.102:

EC medium supplemented with 50 μg/ℓ of MUG (final concentration).

EC medium is as described in subsection (e) of this Section. MUG may

be added to EC medium before autoclaving. EC medium supplemented

with 50 μg/ℓ MUG is commercially available. At least 10 mℓ of EC

medium supplemented with MUG must be used. The inner inverted

fermentation tube may be omitted. The procedure for transferring a total

coliform-positive culture to EC medium supplemented with MUG is as in

subsection (e) of this Section for transferring a total coliform-positive

culture to EC medium. Observe fluorescence with an ultraviolet light

(366 nm) in the dark after incubating tube at 44.5±2° C for 24±2 hours; or

Nutrient agar supplemented with 100 μg/ℓ MUG (final concentration), as

described in Standard Methods, 19th ed. and 20th ed.: Method 9222 G.

This test is used to determine if a total coliform-positive sample, as

determined by the MF technique, contains E. coli. Alternatively, Standard

161

Methods, 18th ed.: Method 9221 B may be used if the membrane filter

containing a total coliform-positive colony or colonies is transferred to

nutrient agar, as described in Method 9221 B (paragraph 3), supplemented

with 100 μg/ℓ MUG. If Method 9221 B is used, incubate the agar plate at

35° Celsius for four hours, then observe the colony or colonies under

ultraviolet light (366-nm) in the dark for fluorescence. If fluorescence is

visible, E. coli are present.

Minimal Medium ONPG-MUG (MMO-MUG) Test, as set forth in

Appendix D of this Part. (The Autoanalysis Colilert System is a MMO-

MUG test.) If the MMO-MUG test is total coliform positive after a 24-

hour incubation, test the medium for fluorescence with a 366-nm

ultraviolet light (preferably with a six-watt lamp) in the dark. If

fluorescence is observed, the sample is E. coli-positive. If fluorescence is

questionable (cannot be definitively read) after 24 hours incubation,

incubate the culture for an additional four hours (but not to exceed 28

hours total), and again test the medium for fluorescence. The MMO-

MUG test with hepes buffer is the only approved formulation for the

detection of E. coli.

The Colisure Test (Autoanalysis Colilert System).

The membrane filter method with MI agar.

The E*Colite® Test.

The m-ColiBlue24® Test.

Readycult Coliforms 100 Presence/Absence Test.

Membrane Filter Technique using Chromocult Coliform Agar.

10)

Colitag® Test.

As an option to the method set forth in subsection (f)(3) of this Section, a supplier

with a total coliform-positive, MUG-negative, MMO-MUG test may further

analyze the culture for the presence of E. coli by transferring a 0.1 mℓ, 28-hour

MMO-MUG culture to EC medium + MUG with a pipet. The formulation and

incubation conditions of the EC medium + MUG, and observation of the results,

are described in subsection (f)(1) of this Section.

This subsection corresponds with 40 CFR 141.21(f)(8), a central listing of all

documents incorporated by reference into the federal microbiological analytical

methods. The corresponding Illinois incorporations by reference are located at

Section 611.102. This statement maintains structural parity with USEPA

Section 611.531

Analytical Requirements

The analytical methods specified in this Section must be used to demonstrate compliance with

the requirements of only 611.Subpart B; they do not apply to analyses performed for the

purposes of Sections 611.521 through 611.527 of this Subpart L. Measurements for pH,

temperature, turbidity, and RDCs must be conducted under the supervision of a certified

operator. Measurements for total coliforms, fecal coliforms and HPC must be conducted by a

laboratory certified by the Agency to do such analysis. The following procedures must be

performed by the following methods, incorporated by reference in Section 611.102:

A supplier shall do as follows:

Conduct analyses of pH in accordance with one of the methods listed at

Section 611.611; and

Conduct analyses of total coliforms, fecal coliforms, heterotrophic

bacteria, and turbidity in accordance with one of the following methods,

and by using analytical test procedures contained in USEPA Technical

Notes, incorporated by reference in Section 611.102, as follows:

Total Coliforms.

BOARD NOTE: The time from sample collection to initiation of

analysis for source (raw) water samples required by Sections

611.521 and 611.532 and Subpart B of this Part only must not

exceed eight hours. The supplier is encouraged but not required to

hold samples below 10° C during transit.

Total coliform fermentation technique: Standard Methods,

18th, 19th, or

20th, or 21st ed.: Method 9221 A, B, and C.

BOARD NOTE: Lactose broth, as commercially available,

may be used in lieu of lauryl tryptose broth if the supplier

conducts at least 25 parallel tests between this medium and

lauryl tryptose broth using the water normally tested and

this comparison demonstrates that the false-positive rate

and false-negative rate for total coliforms, using lactose

broth, is less than 10 percent. If inverted tubes are used to

detect gas production, the media should cover these tubes

at least one-half to two-thirds after the sample is added. No

163

requirement exists to run the completed phase on 10

percent of all total coliform-positive confirmed tubes.

ii)

ed.: Method 9223.

BOARD NOTE: USEPA included the P-A Coliform and

Colisure Tests for testing finished water under the coliform

rule, under Section 611.526, but did not include them for

the purposes of the surface water treatment rule, under this

Section, for which quantitation of total coliforms is

necessary. For these reasons, USEPA included Standard

Methods: Method 9221 C for the surface water treatment

rule, but did not include it for the purposes of the total

coliform rule, under Section 611.526.

Fecal Coliforms.

BOARD NOTE: The time from sample collection to initiation of

analysis for source (raw) water samples required by Sections

611.521 and 611.532 and Subpart B of this Part only must not

0.05 mg/ℓ.

7 The MDL reported for USEPA Method 200.9 (atomic absorption-platform

furnace (stabilized temperature)) was determined using a 2× concentration

step during sample digestion. The MDL determined for samples analyzed

using direct analyses (i.e., no sample digestion) will be higher. Using

multiple depositions, USEPA Method 200.9 is capable of obtaining an MDL

of 0.0001 mg/ℓ.

8 Using selective ion monitoring, USEPA Method 200.8 (ICP-MS) is capable of

obtaining an MDL of 0.0001 mg/ℓ.

9 Measures total cyanides when UV-digestor is used, and “free” cyanides when

UV-digestor is bypassed.

BOARD NOTE: Subsections (a) through (c) of this Section are derived from 40 CFR 141.23

Section 611.611

Inorganic Analysis

Analytical methods are from documents incorporated by reference in Section 611.102. These are

mostly referenced by a short name defined by Section 611.102(a). Other abbreviations are

defined in Section 611.101.

Analysis for the following contaminants must be conducted using the following

methods or an alternative approved pursuant to Section 611.480. Criteria for

analyzing arsenic, chromium, copper, lead, nickel, selenium, sodium, and

thallium with digestion or directly without digestion, and other analytical

procedures, are contained in USEPA Technical Notes, incorporated by reference

in Section 611.102. (This document also contains approved analytical test

methods that remained available for compliance monitoring until July 1, 1996.

These methods are not available for use after July 1, 1996.)

BOARD NOTE: Because MDLs reported in USEPA Environmental Metals

Methods 200.7 and 200.9 were determined using a 2× preconcentration step

during sample digestion, MDLs determined when samples are analyzed by direct

analysis (i.e., no sample digestion) will be higher. For direct analysis of cadmium

and arsenic by USEPA Environmental Metals Method 200.7, and arsenic by

Standard Methods, 18th, 19th, or

20th, or 21st ed., Method 3120 B sample

171

preconcentration using pneumatic nebulization may be required to achieve lower

detection limits. Preconcentration may also be required for direct analysis of

antimony, lead, and thallium by USEPA Environmental Metals Method 200.9;

antimony and lead by Standard Methods, 18th, or 19th, or 21st ed., Method 3113

B; and lead by ASTM Method D3559-96 D or D3559-03 D unless multiple in-

furnace depositions are made.

Alkalinity.

Titrimetric.

ASTM Method D1067-92 B or D1067-02 B; or

ii)

Standard Methods, 18th, 19th, or 20th, or 21st ed.: Method

2320 B.

BOARD NOTE: On March 12, 2007 (at 72 Fed. Reg.

11200), USEPA amended the entry for alkalinity by

titrimetric alkalinity in the table at corresponding 40 CFR

141.23(k)(1) to allow the use of Standard Methods Online

(at www.standardmethods.org), Method 2320 B (as

approved in 1997). The Board has instead cited to the 21st

edition of Standard Methods for the Examination of Water

and Wastewater (the printed version of Standard Methods),

since the version of Method 2320 that appears in that

printed volume is that cited by USEPA as acceptable for

use. USEPA later added Method 2320 B from the 21st

edition of Standard Methods as an approved alternative

method in Appendix A to Subpart C, added on June 3, 2008

(at 73 Fed. Reg. 31616).

BOARD NOTE: On March 12, 2007 (at 72 Fed. Reg. 11200),

USEPA amended the entry for antimony by atomic absorption,

furnace technique, in the table at corresponding 40 CFR

141.23(k)(1) to allow the use of Standard Methods Online (at

www.standardmethods.org), Method 3113 B (as approved in

1999). The Board has instead cited to the 21st edition of Standard

Methods for the Examination of Water and Wastewater (the

printed version of Standard Methods), since the version of Method

3113 that appears in that printed volume is that cited by USEPA as

acceptable for use. USEPA later added Method 3113 B from the

21st edition of Standard Methods as an approved alternative

method in Appendix A to Subpart C, added on June 3, 2008 (at 73

Fed. Reg. 31616).

Axially viewed inductively coupled plasma-atomic emission

spectrometry (AVICP-AES): USEPA Methods: Method 200.5.

BOARD NOTE: USEPA added this method as an approved

alternative method in Appendix A to Subpart C, added on June 3,

2008 (at 73 Fed. Reg. 31616).

Arsenic.

BOARD NOTE: If ultrasonic nebulization is used in the determination of

arsenic by Methods 200.7, 200.8, or Standard Methods, 18th, 19th, or

20th, or 21st ed., 3120 B, the arsenic must be in the pentavalent state to

provide uniform signal response. For methods 200.7 and 3120 B, both

samples and standards must be diluted in the same mixed acid matrix

concentration of nitric and hydrochloric acid with the addition of 100 μℓ

of 30% hydrogen peroxide per 100 mℓ of solution. For direct analysis of

arsenic with method 200.8 using ultrasonic nebulization, samples and

standards must contain one mg/ℓ of sodium hypochlorite.

Inductively-coupled plasma.

BOARD NOTE: Effective January 23, 2006, a supplier may no

longer employ analytical methods using the ICP-AES technology

because the detection limits for these methods are 0.008 mg/ℓ or

higher. This restriction means that the two ICP-AES methods

(USEPA Environmental Metals Method 200.7 and Standard

Methods, Method 3120 B) approved for use for the MCL of 0.05

mg/ℓ may not be used for compliance determinations for the

revised MCL of 0.010 mg/ℓ. However, prior to the 2005 through

2007 compliance period, a supplier may have compliance samples

analyzed with these less sensitive methods.

Section 611.612

Monitoring Requirements for Old Inorganic MCLs

Analyses for the purpose of determining compliance with the old inorganic MCLs

of Section 611.300 are required as follows:

Analyses for all CWSs utilizing surface water sources must be repeated at

yearly intervals.

Analyses for all CWSs utilizing only groundwater sources must be

repeated at three-year intervals.

This subsection (a)(3) corresponds with 40 CFR 141.23(1)(3), which

requires monitoring for the repealed old MCL for nitrate at a frequency

specified by the state. The Board has followed the USEPA lead and

repealed that old MCL. This statement maintains structural consistency

with USEPA rules.

This subsection (a)(4) corresponds with 40 CFR 141.23(1)(4), which

209

authorizes the state to determine compliance and initiate enforcement

action. This statement maintains structural consistency with USEPA

rules.

If the result of an analysis made under subsection (a) of this Section indicates that

the level of any contaminant listed in Section 611.300 exceeds the old MCL, the

supplier must report to the Agency within seven days and initiate three additional

analyses at the same sampling point within one month.

When the average of four analyses made pursuant to subsection (b) of this

Section, rounded to the same number of significant figures as the old MCL for the

substance in question, exceeds the old MCL, the supplier must notify the Agency

and give notice to the public pursuant to Subpart V of this Part. Monitoring after

public notification must be at a frequency designated by the Agency by a SEP

granted pursuant to Section 611.110 and must continue until the old MCL has not

been exceeded in two successive samples or until a different monitoring schedule

becomes effective as a condition to a variance, an adjusted standard, a site

specific rule, an enforcement action, or another SEP granted pursuant to Section

611.110.

This subsection (d) corresponds with 40 CFR 141.23(o), which pertains to

monitoring for the repealed old MCL for nitrate. This statement maintains

structural consistency with USEPA rules.

This subsection (e) corresponds with 40 CFR 141.23(p), which pertains to the use

of existing data up until a date long since expired. This statement maintains

structural consistency with USEPA rules.

Except for arsenic, for which analyses must be made in accordance with Section

611.611, analyses conducted to determine compliance with the old MCLs of

Section 611.300 must be made in accordance with the following methods,

incorporated by reference in Section 611.102.

SUBPART S: GROUNDWATER RULE

Section 611.802

Groundwater Source Microbial Monitoring and Analytical Methods

Triggered source water monitoring.

General requirements. A GWS supplier must conduct triggered source

water monitoring if the following conditions exist:

The supplier does not provide at least 4-log treatment of viruses

(using inactivation, removal, or an Agency-approved combination

of 4-log virus inactivation and removal) before or at the first

customer for each groundwater source; and

The supplier is notified that a sample collected pursuant to Section

611.521 is total coliform-positive, and the sample is not

226

invalidated by the Agency pursuant to Section 611.523.

Sampling requirements. A GWS supplier must collect, within 24 hours

after notification of the total coliform-positive sample, at least one

groundwater source sample from each groundwater source in use at the

time the total coliform-positive sample was collected pursuant to Section

611.521, except as provided in subsection (a)(2)(B) of this Section.

The Agency may, by a SEP issued pursuant to Section 611.110,

extend the 24-hour time limit on a case-by-case basis if it

determines that the supplier cannot collect the groundwater source

water sample within 24 hours due to circumstances beyond the

supplier’s control. In the case of an extension, the Agency must

specify how much time the supplier has to collect the sample.

If approved by the Agency, a supplier with more than one

groundwater source may meet the requirements of this subsection

(a)(2) by sampling a representative groundwater source or sources.

If directed by the Agency by a SEP issued pursuant to Section

611.110, the supplier must submit for Agency approval a triggered

source water monitoring plan that identifies one or more

groundwater sources that are representative of each monitoring site

in the system’s sample siting plan pursuant to Section 611.521 and

that the system intends to use for representative sampling pursuant

to this subsection (a).

A GWS supplier that serves 1,000 or fewer people may use a

repeat sample collected from a groundwater source to meet both

the requirements of Section 611.522 and to satisfy the monitoring

requirements of subsection (a)(2) of this Section for that

groundwater source only if the Agency approves the use of E. coli

as a fecal indicator for source water monitoring pursuant to this

subsection (a) by a SEP issued pursuant to Section 611.110. If the

repeat sample collected from the groundwater source is E.coli

positive, the system must comply with subsection (a)(3) of this

Section.

Additional requirements. If the Agency does not require corrective action

pursuant to Section 611.803(a)(2) for a fecal indicator-positive source

water sample collected pursuant to subsection (a)(2) of this Section that is

not invalidated pursuant to subsection (d) of this Section, the system must

collect five additional source water samples from the same source within

24 hours after being notified of the fecal indicator-positive sample.

Consecutive and wholesale systems.

227

In addition to the other requirements of this subsection (a), a

consecutive GWS supplier that has a total coliform-positive

sample collected pursuant to Section 611.521 must notify the

wholesale systems within 24 hours after being notified of the total

coliform-positive sample.

In addition to the other requirements of this subsection (a), a

wholesale GWS supplier must comply with the following

requirements:

A wholesale GWS supplier that receives notice from a

consecutive system it serves that a sample collected

pursuant to Section Section 611.521 is total coliform-

positive must, within 24 hours after being notified, collect a

sample from its groundwater sources pursuant to subsection

(a)(2) of this Section and analyze it for a fecal indicator

pursuant to subsection (c) of this Section.

ii)

If the sample collected pursuant to subsection (a)(4)(B)(i)

of this section is fecal indicator-positive, the wholesale

GWS supplier must notify all consecutive systems served

by that groundwater source of the fecal indicator source

water positive within 24 hours of being notified of the

groundwater source sample monitoring result and must

meet the requirements of subsection (a)(3) of this Section.

Exceptions to the triggered source water monitoring requirements. A

GWS supplier is not required to comply with the source water monitoring

requirements of subsection (a) of this Section if either of the following

conditions exists:

The Agency determines, and documents in writing, by a SEP

issued pursuant to Section 611.110, that the total coliform-positive

sample collected pursuant to Section 611.521 is caused by a

distribution system deficiency; or

The total coliform-positive sample collected pursuant to Section

611.521 is collected at a location that meets Agency criteria for

distribution system conditions that will cause total coliform-

positive samples.

Assessment source water monitoring. If directed by the Agency by a SEP issued

pursuant to Section 611.110, a GWS supplier must conduct assessment source

water monitoring that meets Agency-determined requirements for such

monitoring. A GWS supplier conducting assessment source water monitoring

may use a triggered source water sample collected pursuant to subsection (a)(2) of

228

this Section to meet the requirements of subsection (b) of this Section. Agency-

determined assessment source water monitoring requirements may include the

following:

Collection of a total of 12 groundwater source samples that represent each

Invalidation of a fecal indicator-positive groundwater source sample.

A GWS supplier may obtain Agency invalidation of a fecal indicator-

positive groundwater source sample collected pursuant to subsection (a) of

this Section only under either of the following conditions:

The supplier provides the Agency with written notice from the

laboratory that improper sample analysis occurred; or

The Agency determines and documents in writing by a SEP issued

pursuant to Section 611.110 that there is substantial evidence that a

231

fecal indicator-positive groundwater source sample is not related to

source water quality.

If the Agency invalidates a fecal indicator-positive groundwater source

sample, the GWS supplier must collect another source water sample

pursuant to subsection (a) of this Section within 24 hours after being

notified by the Agency of its invalidation decision, and the supplier must

have it analyzed for the same fecal indicator using the analytical methods

in subsection (c) of this Section. The Agency may extend the 24-hour

time limit on a case-by-case basis if the supplier cannot collect the source

water sample within 24 hours due to circumstances beyond its control. In

the case of an extension, the Agency must specify how much time the

system has to collect the sample.

Sampling location.

Any groundwater source sample required pursuant to subsection (a) of this

Section must be collected at a location prior to any treatment of the

groundwater source unless the Agency approves a sampling location after

treatment.

If the supplier’s system configuration does not allow for sampling at the

well itself, it may collect a sample at an Agency-approved location to meet

the requirements of subsection (a) of this Section if the sample is

representative of the water quality of that well.

New sources. If directed by the Agency by a SEP issued pursuant to Section

611.110, a GWS supplier that places a new groundwater source into service after

(Source: Amended at 32 Ill. Reg. ________, effective ______________________)

Section 611.1007

Source Water Monitoring Requirements: Grandfathering Previously

Collected Data

Initial source monitoring and Cryptosporidium samples.

A supplier may comply with the initial source water monitoring

requirements of Section 611.1001(a) by grandfathering sample results

collected before the supplier is required to begin monitoring (i.e.,

previously collected data). To be grandfathered, the sample results and

analysis must meet the criteria in this Section and the Agency must

approve the use of the data by a SEP issued pursuant to Section 611.110.

A filtered system supplier may grandfather Cryptosporidium samples to

meet the requirements of Section 611.1001(a) when the supplier does not

236

have corresponding E. coli and turbidity samples. A supplier that

grandfathers Cryptosporidium samples without E. coli and turbidity

samples is not required to collect E. coli and turbidity samples when it

completes the requirements for Cryptosporidium monitoring pursuant to

Section 611.1001(a).

E. coli sample analysis. The analysis of E. coli samples must meet the analytical

method and approved laboratory requirements of Sections 611.1004 and

611.1005.

Cryptosporidium sample analysis. The analysis of Cryptosporidium samples

must meet the criteria in this subsection (c).

Laboratories analyzed Cryptosporidium samples using one of the

following analytical methods:

USEPA OGWDW Methods, Method 1623 (05), incorporated by

reference in Section 611.102;

USEPA OGWDW Methods, Method 1622 (05), incorporated by

reference in Section 611.102;

USEPA OGWDW Methods, Method 1623 (01), incorporated by

reference in Section 611.102;

USEPA OGWDW Methods, Method 1622 (01), incorporated by

reference in Section 611.102;

USEPA OGWDW Methods, Method 1623 (99), incorporated by

reference in Section 611.102; or

USEPA OGWDW Methods,

Method 1622 (99), incorporated by

reference in Section 611.102.

For each Cryptosporidium sample, the laboratory analyzed at least 10

ℓ

sample or at least 2 mℓ of packed pellet or as much volume as could be

filtered by two filters that USEPA approved for the methods listed in

subsection (c)(1) of this Section.

Sampling location. The sampling location must meet the conditions in Section

611.1003.

Sampling frequency. Cryptosporidium samples were collected no less frequently

than each calendar month on a regular schedule, beginning no earlier than January

1999. Sample collection intervals may vary for the conditions specified in

Section 611.1002(b)(1) and (b)(2) if the supplier provides documentation of the

237

condition when reporting monitoring results.

The Agency may, by a SEP issued pursuant to Section 611.110, approve

grandfathering of previously collected data where there are time gaps in

the sampling frequency if the supplier conducts additional monitoring that

the Agency has specified by a SEP issued pursuant to Section 611.110 to

ensure that the data used to comply with the initial source water

monitoring requirements of Section 611.1001(a) are seasonally

representative and unbiased.

A supplier may grandfather previously collected data where the sampling

frequency within each month varied. If the Cryptosporidium sampling

frequency varied, the supplier must follow the monthly averaging

procedure in Section 611.1010(b)(5) or Section 611.1012(a)(3), as

applicable, when calculating the bin classification for a filtered system

supplier or the mean Cryptosporidium concentration for an unfiltered

system supplier.

Reporting monitoring results for grandfathering. A supplier that requests to

grandfather previously collected monitoring results must report the following

information by the applicable dates listed in this subsection. A supplier must

report this information to the Agency.

A supplier must report that it intends to submit previously collected

monitoring results for grandfathering. This report must specify the

number of previously collected results the supplier will submit, the dates

of the first and last sample, and whether a supplier will conduct additional

source water monitoring to meet the requirements of Section 611.1001(a).

The supplier must report this information no later than the applicable date

set forth in Section 611.1002.

A supplier must report previously collected monitoring results for

grandfathering, along with the associated documentation listed in

subsections (f)(2)(A) through (f)(2)(D) of this Section, no later than two

months after the applicable date listed in Section 611.1001(c).

For each sample result, a supplier must report the applicable data

elements in Section 611.1006.

A supplier must certify that the reported monitoring results include

all results that it generated during the time period beginning with

the first reported result and ending with the final reported result.

This applies to samples that were collected from the sampling

location specified for source water monitoring pursuant to this

Subpart Z, which were not spiked, and which were analyzed using

the laboratory’s routine process for the analytical methods listed in

238

this Section.

The supplier must certify that the samples were representative of a

plant’s source waters and the source waters have not changed. It

must report a description of the sampling locations, which must

address the position of the sampling location in relation to its water

sources and treatment processes, including points of chemical

addition and filter backwash recycle.

For Cryptosporidium samples, the laboratory or laboratories that

analyzed the samples must provide a letter certifying that the

quality control criteria specified in the methods listed in subsection

(c)(1) of this Section were met for each sample batch associated

with the reported results. Alternatively, the laboratory may

provide bench sheets and sample examination report forms for

each field, matrix spike, initial precision and recovery, ongoing

precision and recovery, and method blank sample associated with

the reported results.

If the Agency determines that a previously collected data set submitted for

grandfathering was generated during source water conditions that were not

normal for the supplier, such as a drought, the Agency may, by a SEP issued

pursuant to Section 611.110, disapprove the data. Alternatively, the Agency may,

by a SEP issued pursuant to Section 611.110, approve the previously collected

data if the supplier reports additional source water monitoring data, as determined

by the Agency, to ensure that the data set used pursuant to Section 611.1010 or

Section 611.1012 represents average source water conditions for the supplier.

If a supplier submits previously collected data that fully meet the number of

samples required for initial source water monitoring pursuant to Section

611.1001(a), and some of the data are rejected due to not meeting the

requirements of this Section, the supplier must conduct additional monitoring to

replace rejected data on a schedule that the Agency has approved by a SEP issued

pursuant to Section 611.110. A supplier is not required to begin this additional

monitoring until two months after notification that data have been rejected and

additional monitoring is necessary.
