Summary and Purpose of Amendments:

A more complete description of these adopted amendments may be found in the Board's

opinion and order of November 15, 2007, in Board docket R07-8. This rulemaking

adopts amendments to Part 811 that are intended to update the Board's solid waste

disposal regulations to reflect practical experience gained through the implementation of

those rules and expanded technical and scientific knowledge achieved since the Board

first adopted these standards in 1990. This rulemaking is based on a proposal that was

filed with the Board on July 27, 2006, by the Illinois Chapter of the National Solid

Wastes Management Association (NSWMA) with the concurrence of the Illinois

Environmental Protection Agency (Agency).

The amendments adopted in this rulemaking include changes that pertain to issues

including leachate monitoring, hydrogeologic site investigation, groundwater monitoring

systems, and groundwater quality standards.

The amendments to the leachate monitoring include adding a list of 202 constituents to be

monitored. The amendments also add a minimum number of leachate monitoring

locations at landfill units. For the first two years of landfill operation, the amendments

change the frequency of leachate monitoring frequency from quarterly to semi-annual

monitoring. The adopted amendments also require sampling from each monitoring

location at least once every two years.

At Section 811.315(e)(1)(G)(i), the Board replaced the reference in the rules to 'public or

food processing water supply standard at 35 Ill. Adm. Code 302' with a reference to the

groundwater standards found at 35 Ill. Adm. Code 620. This amendment replaces the list

of constituents under public or food processing water supply standards with a more

comprehensive list of constituents under the Board's groundwater standards.

The amendments to the groundwater monitoring systems address the depth of monitoring

wells. Specifically, the final amendments require an operator to measure the depth of

groundwater monitoring wells that do not contain dedicated pumps on an annual basis.

The amendments also require that, at groundwater monitoring wells containing dedicated

ILLINOIS REGISTER

POLLUTION CONTROL BOARD

NOTICE OF ADOPTED AMENDMENTS

pumps, the operator must measure the depth of the well every five years or when the

pump is serviced.

Additional amendments to monitoring requirements include adding a specific list of

indicator constituents, adding a specific list of organic chemicals for which groundwater

must be monitored, and increasing the frequency of the monitoring for the specified

organic parameters.

The changes to the assessment monitoring provisions under Section 811.319(b) include

specifying deadlines for submission and implementation of an assessment monitoring

plan.

The amendments adopt a number of changes to the groundwater quality standard

provisions under Section 811.320. These changes replace references to public water

supply standards with references to groundwater standards, clarify the establishment of

background concentrations, and update statistical analysis procedures.

Section 811.318 Design, Construction, and Operation of Groundwater

Monitoring Systems

All potential sources of discharges to groundwater within the facility, including,

but not limited to, all waste disposal units and the leachate management system,

shall be identified and studied through a network of monitoring wells operated

during the active life of the unit and for the time after closure specified in

accordance with Section 811.319. Monitoring wells designed and constructed as

part of the monitoring network shall be maintained along with records that

include, but are not limited to, exact well location, well size, type of well, the

design and construction practice used in its installation and well and screen

depths.

Standards for the Location of Monitoring Points

A network of monitoring points shall be established at sufficient locations

downgradient with respect to groundwater flow and not excluding the

downward direction, to detect any discharge of contaminants from any

part of a potential source of discharge.

Monitoring wells shall be located in stratigraphic horizons that could serve

as contaminant migration pathways.

Monitoring wells shall be established as close to the potential source of

discharge as possible without interfering with the waste disposal

operations, and within half the distance from the edge of the potential

within a single facility may be combined into a single monitoring network,

provided that discharges from any part of all potential sources can be

detected.

A minimum of at least one monitoring well shall be established at the edge

of the zone of attenuation and shall be located downgradient with respect

to groundwater flow and not excluding the downward direction, from the

unit. Such well or wells shall be used to monitor any statistically

significant increase in the concentration of any constituent, in accordance

with Section 811.320(e) and shall be used for determining compliance

with an applicable groundwater quality standard of Section 811.320. An

observed statistically significant increase above the applicable

groundwater quality standards of Section 811.320 in a well located at or

beyond the compliance boundary shall constitute a violation.

Maximum Allowable Predicted Concentrations

The operator shall use the same calculation methods, data, and assumptions as

used in the groundwater impact assessment to predict the concentration over time

and space of all constituents chosen to be monitored in accordance with Section

811.319 at all monitoring points. The predicted values shall be used to establish

the maximum allowable predicted concentrations (MAPC) at each monitoring

point. The MAPCs calculated in this subsection shall be applicable within the

zone of attenuation.

Standards for Monitoring Well Design and Construction

clogging. Screens shall be fabricated from material expected to be inert

with respect to the constituents of the groundwater to be sampled.

Annular space above the well screen section shall be sealed with a

relatively impermeable, expandable material such as a cement/bentonite

grout, which does not react with or in any way affect the sample, in order

to prevent contamination of samples and groundwater and avoid

interconnections. The seal shall extend to the highest known seasonal

groundwater level.

The annular space shall be back-filled with expanding cement grout from

an elevation below the frost line and mounded above the surface and

sloped away from the casing so as to divert surface water away.

The annular space between the upper and lower seals and in the

unsaturated zone may be back-filled with uncontaminated cuttings.

All wells shall be covered with vented caps and equipped with devices to

protect against tampering and damage.

All wells shall be developed to allow free entry of water, minimize

turbidity of the sample, and minimize clogging.

The transmissivity of the zone surrounding all well screens shall be

established by field testing techniques.

Other sampling methods and well construction techniques may be utilized

if they provide equal or superior performance to the requirements of this

subsection.

quantitative detection limits and the degree of error for analysis of each

chemical constituent.

The operator shall establish a sample preservation and shipment procedure

that maintains the reliability of the sample collected for analysis.

The operator shall institute a chain of custody procedure to prevent

tampering and contamination of the collected samples prior to completion

of analysis.

At a minimum, the operator shall sample the following parameters at all

wells at the time of sample collection and immediately before filtering and

preserving samples for shipment:

The elevation of the water table;

The depth of the well below ground;

GB) pH;

DC) The temperature of the sample; and

ED) Specific Conductance.

The operator must measure the depth of the well below ground on an

annual basis, at wells that do not contain dedicated pumps. The operator

must measure the depth of the well below ground every 5 years, or

whenever the pump is pulled. in wells with dedicated pumps.

78) In addition to the requirements of subsections (e)(1) through (e)(6), the

following requirements shall apply to MSWLF units:

A) Each time groundwater is sampled, an owner or operator of a

MSWLF unit shall:

ILLINOIS REGISTER

POLLUTION CONTROL BOARD

NOTICE OF ADOPTED AMENDMENTS

Any use of the term maximum allowable predicted concentration in this Section is

a reference to Section 811.318(c). The operator shall implement a detection

monitoring program in accordance with the following requirements:

1) Monitoring

Schedule and Frequency

A) The

monitoring period shall begin as soon as waste is placed into

the unit of a new landfill or within one year of the effective date of

this Part for an existing landfill. Monitoring shall continue for a

minimum period of fifteen years after closure, or in the case of

MSWLF units, a minimum period of 30 years after closure, except

as otherwise provided by subsection (a)(1)(C) of this Section. The

operator shall sample all monitoring points for all potential sources

of contamination on a quarterly basis except as specified in

subsection (a)(3), for a period of five years from the date of

issuance of the initial permit for significant modification under 35

Ill. Adm. Code 814.104 or a permit for a new unit pursuant to 35

Ill. Adm. Code 813.104. After the initial five-year period, the

POLLUTION CONTROL BOARD

NOTICE OF ADOPTED AMENDMENTS

semi-annual basis, provided the operator has submitted the

certification described in 35 Ill. Adm. Code 813.304(b).

Alternatively, after the initial five-year period, the Agency shall

allow sampling on a semi-annual basis where the operator

demonstrates that monitoring effectiveness has not been

compromised, that sufficient quarterly data has been collected to

characterize groundwater, and that leachate from the monitored

unit does not constitute a threat to groundwater. For the purposes

of this Section, the source shall be considered a threat to

groundwater if the results of the monitoring indicate either that the

concentrations of any of the constituents monitored within the zone

of attenuation is above the maximum allowable predicted

concentration for that constituent or, for existing landfills, subject

to 35 Ill. Adm. Code 814, Subpart D, that the concentration of any

constituent has exceeded the applicable standard at the compliance

boundary as defined in 35 Ill. Adm. Code 814.402(b)(3).

B) Beginning

fifteen years after closure of the unit, or five years after

all other potential sources of discharge no longer constitute a threat

to groundwater, as defined in subsection (a)(1)(A), the monitoring

frequency may change on a well by well basis to an annual

schedule if either of the following conditions exist. However,

monitoring shall return to a quarterly schedule at any well where a

statistically significant increase is determined to have occurred in

accordance with Section 811.320(e), in the concentration of any

constituent with respect to the previous sample.

All constituents monitored within the zone of attenuation

have returned to a concentration less than or equal to ten

percent of the maximum allowable predicted concentration;

ii)

All constituents monitored within the zone of attenuation

are less than or equal to their maximum allowable predicted

concentration for eight consecutive quarters.

C) Monitoring shall be continued for a minimum period of: thirty 30

years after closure at MSWLF units, except as otherwise provided

by subsections (a)(1)(D) and (a)(1)(E), below; five years after

ILLINOIS REGISTER

POLLUTION CONTROL BOARD

NOTICE OF ADOPTED AMENDMENTS

closure at landfills, other than MSWLF units, which are used

exclusively for disposing waste generated at the site; or fifteen 15

years after closure at all other landfills regulated under this Part.

Monitoring, beyond the minimum period, may be discontinued

under the following conditions:

i) No

statistically significant increase is detected in the

concentration of any constituent above that measured and

recorded during the immediately preceding scheduled

sampling for three consecutive years, after changing to an

annual monitoring frequency; or

Immediately after contaminated leachate is no longer

generated by the unit.

The Agency may reduce the groundwater monitoring period at a

MSWLF unit upon a demonstration by the owner or operator that

the reduced period is sufficient to protect human health and

environment.

An owner or operator of a MSWLF unit shall petition the Board

for an adjusted standard in accordance with Section 811.303, if the

owner or operator seeks a reduction of the postclosure care

monitoring period for all of the following requirements:

Inspection and maintenance (Section 811.111);

Section 811.320 Groundwater

Quality Standards

a) Applicable Groundwater Quality Standards

1) Groundwater quality shall be maintained at each constituent's background

concentration, at or beyond the zone of attenuation. The applicable

groundwater quality standard established for any constituent shall be:

The background concentration; or

The Board established standard adjusted by the Board in

accordance with the justification procedure of subsection (b).

2) Any statistically significant increase above an applicable groundwater

quality standard established pursuant to subsection (a)(1) that is

attributable to the facility and which occurs at or beyond the zone of

attenuation within 100 years after closure of the last unit accepting waste

within such a facility shall constitute a violation.

3) For the purposes of this Part:

A) "Background concentration" means that concentration of a

constituent that is established as the background in accordance

with subsection (d); and

. "

. :

ILLINOIS REGISTER

POLLUTION CONTROL BOARD

NOTICE OF ADOPTED AMENDMENTS

B) "Board

established standard" is the concentration of a constituent

adopted by the Board as a

water supplies under 35 Ill. Adm. Code 302 or as a groundwater

quality standard adopted by the Board pursuant to Section 14.4 of

the Act or Section 8 of the Illinois Groundwater Protection Act-,-

whichever is lower.

b) Justification

for Adjusted Groundwater Quality Standards

1) An

operator may petition the Board for an adjusted groundwater quality

standard in accordance with the procedures specified in Section 28.1 of the

Act and 35 Ill. Adm. Code 106.110 through 106.416104.400.Subpart D.

2) For

groundwater which contains naturally occurring constituents which

meet the applicable requirements of 35 Ill. Adm. Code 302.301, 302.304,

and 302.305,620.410, 620.420, 620.430, or 620.440 the Board will specify

adjusted groundwater quality standards no greater than those of 35 Ill.

Adm. Code 302.301, 302.304, and 302.305,620.410, 620.420, 620.430 or

620.440, respectively, upon a demonstration by the operator that:

The change in standards will not interfere with, or become

injurious to, any present or potential beneficial uses for such water;

The change in standards is necessary for economic or social

development, by providing information including, but not limited

to, the impacts of the standards on the regional economy, social

disbenefits such as loss of jobs or closing of landfills, and

economic analysis contrasting the health and environmental

benefits with costs likely to be incurred in meeting the standards,:,

and

All technically feasible and economically reasonable methods are

being used to prevent the degradation of the groundwater quality.

3) Notwithstanding

subsection (b)(2), in no case shall the Board specify

adjusted groundwater quality standards for a MSWLF unit greater than the

following levels set forth below:

302.305,620.410, 620.420, 620.430 or 620.440, the Board will specify

adjusted groundwater quality standards, upon a demonstration by the

operator that:

The groundwater does not presently serve as a source of drinking

water:,

The change in standards will not interfere with, or become

injurious to, any present or potential beneficial uses for such

waters;

ILLINOIS REGISTER

POLLUTION CONTROL BOARD

NOTICE OF ADOPTED AMENDMENTS

The change in standards is necessary for economic or social

development, by providing information including, but not limited

to, the impacts of the standards on the regional economy, social

disbenefits such as loss of jobs or closing of landfills, and

economic analysis contrasting the health and environmental

benefits with costs likely to be incurred in meeting the standards;

and

The groundwater cannot presently, and will not in the future, serve

as a source of drinking water because:

It is impossible to remove water in usable quantities;

ii)

The groundwater is situated at a depth or location such that

recovery of water for drinking purposes is not

technologically feasible or economically reasonable;

iii)

The groundwater is so contaminated that it would be

economically or technologically impractical to render that

water fit for human consumption;

iv)

The total dissolved solids content of the groundwater is

more than 3,000 mg/1 and that water will not be used to

serve a public water supply system; or

The total dissolved solids content of the groundwater

exceeds 10,000 mg/l.

c) Determination

of the Zone of Attenuation

The zone of attenuation, within which concentrations of constituents in

leachate discharged from the unit may exceed the applicable groundwater

quality standard of this Section, is a volume bounded by a vertical plane at

the property boundary or 100 feet from the edge of the unit, whichever is

less, extending from the ground surface to the bottom of the uppermost

aquifer and excluding the volume occupied by the waste.

Zones of attenuation shall not extend to the annual high water mark of

navigable surface waters.

ILLINOIS REGISTER

POLLUTION CONTROL BOARD

NOTICE OF ADOPTED AMENDMENTS

3) Overlapping zones of attenuation from units within a single facility may

be combined into a single zone for the purposes of establishing a

monitoring network.

d) Establishment of Background Concentrations

1) The initial monitoring to determine background concentrations shall

commence during the hydrogeological assessment required by Section

811.315. The background concentrations for those parameters identified

in Sections 811.315(e)(1)(G) and 811.319(a)(2) and (a)(3) shall be

established based on consecutive quarterly sampling of wells for a

minimum of one year, monitored in accordance with the requirements of

subsections (d)(2), (d)(3) and (d)(4), which may be adjusted during the

operation of a facility. Non-consecutive data may be considered by the

Agency, if only one data point from a quarterly event is missing, and it can

be demonstrated that the remaining data set is representative of

consecutive data in terms of any seasonal or temporal variation. Statistical

tests and procedures shall be employed, in accordance with subsection (e),

depending on the number, type and frequency of samples collected from

the wells, to establish the background concentrations.

Adjustments to the background concentrations shall be made only if

changes in the concentrations of constituents observed in

upgradientbackground wells over time are determined, in accordance with

subsection (e), to be statistically significant, and due to natural temporal

or spatial variability or due to an off-site source not associated with the

landfill or the landfill activities. Such adjustments may be conducted no

more frequently than once every two years during the operation of a

facility and modified subject to approval by the Agency. Non-consecutive

data may be used for an adjustment upon Agency approval. Adjustments

to the background concentration shall not be initiated prior to November

27, 2009 unless required by the Agency.

Background concentrations determined in accordance with this subsection

shall be used for the purposes of establishing groundwater quality

standards, in accordance with subsection (a). The operator shall prepare a

list of the background concentrations established in accordance with this

subsection. The operator shall maintain such a list at the facility, shall

ILLINOIS REGISTER

POLLUTION CONTROL BOARD

NOTICE OF ADOPTED AMENDMENTS

submit a copy of the list to the Agency for establishing standards in

accordance with subsection (a), and shall provide updates to the list within

ten days of any change to the list.

24) A network of monitoring wells shall be established upgradient from the

unit, with respect to groundwater flow, in accordance with the following

standards, in order to determine the background concentrations of

constituents in the groundwater:

The wells shall be located at such a distance that discharges of

contaminants from the unit will not be detectable;

The wells shall be sampled at the same frequency as other

monitoring points to provide continuous background concentration

data, throughout the monitoring period; and

The wells shall be located at several depths to provide data on the

spatial variability.

3-5) A

determination of background concentrations may include the sampling

of wells that are not hydraulically upgradient of the waste unit where:

Hydrogeologic conditions do not allow the owner or operator to

determine what wells are hydraulically upgradient of the waste;

and

Sampling at other wells will provide an indication of background

concentrations that is representative of that which would have been

provided by upgradient wells.

46) If background concentrations cannot be determined on site, then

alternative background concentrations may be determined from actual

monitoring data from the aquifer of concern, which includes, but is not

limited to, data from another landfill site that overlies the same aquifer.

e) Statistical Analysis of Groundwater Monitoring Data

1) Statistical tests shall be used to analyze groundwater monitoring data.

One or more of the normal theory statistical tests listed in subsection (e)(4)

ILLINOIS REGISTER

POLLUTION CONTROL BOARD

NOTICE OF ADOPTED AMENDMENTS

shall be chosen first for analyzing the data set or transformations of the

data set. Where such normal theory tests are demonstrated to be

inappropriate, tests listed in subsection (e)(5) or a test in accordance with

subsection (0(6) shall be used. Any statistical test chosen from

.subsections (e)(1) or (e)(5), theThe level of significance (Type I error

level) shall be no less than 0.01, for individual well comparisons, and no

less than 0.05, for multiple well comparisons. The statistical analysis shall

include, but not be limited to, the accounting of data below the detection

limit of the analytical method used, the establishment of background

concentrations and the determination of whether statistically significant

changes have occurred in:

The concentration of any chemical constituent with respect to the

background concentration or maximum allowable predicted

concentration; and

The established background concentration of any chemical

constituents over time.

The statistical test or tests used shall be based upon the sampling and

collection protocol of Sections 811.318 and 811.319.

3) Monitored data that are below the level of detection shall be reported as

not detected (ND). The level of detection for each constituent shall be the

impractical quantitation limit (PQL), and shall be the lowest

concentration of that constituent which can be measured and reported with

99 percent confidence that the true value is greater than zero, which

defined as the method detection limit (MDL) that is protective of human

health and the environment, and can be achieved within specified limits of

precision and accuracy during routine laboratory operating conditions. In

no case, shall the PQL be established above the level that the Board has

established for a groundwater quality standard under the Illinois

Groundwater Protection Act 1415 ILCS 551. The following procedures

shall be used to analyze such data, unless an alternative procedure in

accordance with subsection (e)(64), is shown to be applicable:

A) Where the percentage of nondetects in the data base used is less

than 15 percent, the operator shall replace NDs with the MDLPQL

ILLINOIS REGISTER

POLLUTION CONTROL BOARD

NOTICE OF ADOPTED AMENDMENTS

Normal Theory statistical tests listed in subsection (c)(1);

Where the percentage of nondetects in the data base or data

transformations used is between 15 and 50 percent, and the data

are normally distributed, the operator shall use Cohen's or

Aitchison's adjustment to the sample mean and standard deviation,

followed by one or more of the tests listed in subsection (e)(1)(C).

However, where data are not normally distributed, the perator

an applicable statistical procedure;

Where the percentage of nondetects in the database used is above

50 percent, then the owner or operator shall use the test of

proportions listed in an alternative procedure in accordance with

subsection (e)(4).

4) Normal

theory statistical tests:

Student t test including, but not limited to, Cochran's

Approximation to the Behren Fisher (CABF) t test and Averaged

Replicate (AR) t test.

Parametric analysis of variance (ANOVA) followed by one or

more of the multiple comparison procedures including, but not

limited to, Fisher's L ast Significant Difference (LSD), Student

Mewman Kucl procedure, Duncan's New Multiple Range Test and

Tukey's W procedure.

Control Charts, Prediction Intervals and Tolerance Intervals, for

hall be specified by the Agency in

accordance with the requirements of 35 Ill. Adm. Code 721.197(i).

Nonparametric statistical tests shall include: Mann Whitney U test,

Kruskal Wallis test, a nonparametric analysis of variance
