OPINION AND ORDER OF THE BOARD (by R.C. Flemal):
 

BACKGROUND

 
Under Section 17.5 of the Environmental Protection Act (Act) (415 ILCS 5/17.5 (1998)), the Board today adopts amendments to the Illinois regulations that are “identical in substance” (IIS) to the National Primary Drinking Water regulations (NPDWRs) adopted by the United States Environmental Protection Agency (USEPA). These regulations implement sections 1412(b), 1414(c), 1417(a), and 1445(a) of the Safe Drinking Water Act (SDWA), 42 U.S.C. §§ 300g-1(b), 300g-3(c), 300g-6(a), and 300j-4(a)(1996). The nominal timeframe of this docket includes SDWA amendments that the USEPA adopted in the period from July 1, 1999, through December 31, 1999. The federal SDWA regulations are found at 40 C.F.R. §§ 141 and 142. The USEPA took two actions during the nominal timeframe period that could necessitate Board action, but, as explained below, in response to public comment the Board is incorporating only one federal action into the Board’s rules. The final rule adopted today includes the addition of analytical methods approved for determining compliance with the drinking water regulations.
 
Section 17.5 of the Act (415 ILCS 5/17.5 (1998)) provides for quick adoption of regulations that are “identical in substance” to federal regulations that the USEPA adopts to implement sections 1412(b), 1414(c), 1417(a), and 1445(a) of the SDWA. Section 17.5 of the Act also provides that Title VII of the Act (415 ILCS 5/1 et seq. (1998)) and Section 5 of the Administrative Procedure Act (APA) (5 ILCS 100/5-35 & 5-40 (1998)) do not apply to the Board’s adoption of IIS regulations. Accordingly, this rulemaking is not subject to first or second-notice review by the Joint Committee on Administrative Rules (JCAR). However, to facilitate receipt of public comments, the Board’s June 8, 2000 proposal for public comment was published in the Illinois Register. 24 Ill. Reg. 8728 (June 30, 2000).
 

 Section 7.2(b) of the Act (415 ILCS 5/7.2 (1998)) requires the Board to complete its IIS rulemaking actions within one year of the date of the earliest federal amendments involved in a docket. In this docket, the earliest federal action requiring Board action occurred on September 17, 1999. Thus, the Board must complete its rulemaking activity in this docket prior to September 17, 2000.

 

FEDERAL ACTIONS CONSIDERED IN THIS RULEMAKING

 This rulemaking incorporates certain federal amendments that occurred during the period of July 1, 1999, through December 31, 1999. The SDWA regulations are found at 40 C.F.R. §§ 141-142. The USEPA amended the federal SDWA regulations two times during that period: September 17, 1999, and December 1, 1999. This rulemaking considers both of these actions. As explained below, only the December 1, 1999 action requires corresponding Board action.

The federal amendments incorporated into this rulemaking are summarized as follows:

Federal Action
 
64 Fed. Reg. 50556
(September 17, 1999)
 
 
 
 
 
 
64 Fed. Reg. 67450
(December 1, 1999)
 
 
 
 
 
  		 
   		 Summary
 
Revisions to the Unregulated Contaminant Monitoring Regulation for Public Water. The USEPA adopted amendments requiring public water supplies to monitor for unregulated drinking water contaminants. The USEPA adopted the amendments under section 1445(a) of SDWA.
 
National Primary and Secondary Drinking Water Regulations: Analytical Methods for Chemical and Microbiological Contaminants and Revisions to Laboratory Certification Requirements. The USEPA amended the rules setting forth the analytical methods approved for use in demonstrating compliance with the SDWA requirements.

Public Comments Received

 
The Board adopted a proposal for public comment in this matter by order dated June 8, 2000. The “Notices of Proposed Amendments” appeared in the June 30, 2000 issue of the Illinois Register at 24 Ill. Reg. 8728. The Board accepted public comments on the proposal for a 45-day period following publication in the Illinois Register. The comment period expired on August 15, 2000.
 
The Board received four comments during the public comment (PC) period. Those comments are as follows:
 

PC 1 Identical First Notice Line Numbered Version of proposed amendments from JCAR (received June 29, 2000).

 

   
PC 2 July 24, 2000 memo from Deborah Connelly, JCAR (received July 25, 2000).
PC 3 August 9, 2000 letter from David S. Horak, Safe Drinking Water Branch, USEPA, Region 5 (received August 15, 2000).
PC 4 August 14, 2000 letter from Lou Allyn Byus, Assistant Manager - Field Operations, Division of Water Supplies, Illinois EPA (received August 18, 2000).
These public comments are discussed in more detail later in this opinion.

 
Response to JCAR Additional Questions

 

In addition to PC 1, the Board received public comment from JCAR in PC 2, which included two inquiries from JCAR. It is more efficient to address these questions here, rather than later. The first question addressed incorporating by reference certain sections of the unregulated contaminant monitoring regulations, as proposed by the Board. As the Board is not adopting the proposed program in response to Illinois Environmental Protection Agency (Agency) and USEPA comments that the proposed rules were not federally required to be adopted as IIS rules, the issue is no longer relevant.
 
The second question in PC 2 addressed a section of the Board’s June 8, 2000 proposal for public comment, appearing at page 4. The section reads as follows:
 

Board Amendments not Directly Federally Driven
 

The Board is updating all C.F.R. citations in the affected sections of this rulemaking to the 1999 version. The Board is also amending Section 611.310(a) and the Section 611.310(c) Board Note to correct any ambiguity in the regulations for the purpose of avoiding confusion to the regulated community. Section 611.310 is applicable to all public water systems. The Board is also making numerous technical changes suggested by JCAR, the USEPA, and the Agency.
 
JCAR questioned the Board’s authority to make such changes. JCAR’s inquiry points out that the Board’s caption of this portion of the opinion is not precisely accurate, and is in need of revision.
 
In every IIS rulemaking, the Board makes various necessary changes to any Section of the Administrative Code that may be open as a result of USEPA actions taken during the update period. The Board updates references to the most recent version of the C.F.R. and various statutes and ensures that the regulations are consistent with the requirements of the C.F.R. The Board also corrects any spelling or punctuation errors that may be present. The Board performs these functions to provide the regulated community with cost effective and accurate regulations. JCAR also suggests changes to the regulations that are not a result of the most recent federal amendments.
 
Section 17.5 of the Act mandates that the Board adopt regulations that are “identical in substance” to the Primary Drinking Water regulations. 415 ILCS 5/17.5 (1998). If the Board could not make corrections to the regulations of the type described above to correct any observed error, omission, or lack of conformity with rules of the Secretary of State, the Illinois regulations would not become or remain “identical in substance” to the federal regulations.
 
Section 7.2(a) of the Act contemplates the necessity of such changes in the third sentence, in which it directs that “the only changes that may be made by the Board to the federal regulations are those changes that in no way change the scope or meaning of any portion of the regulations.” 415 ILCS 5/7.2(a) (1998). The Board finds that the changes described in the quoted passage of the opinion above are well within its statutory authority, and the Board will continue to make them in its IIS rulemakings. However, acknowledging the misnomer, i.e., “Board Amendments not Federally Driven” identified by JCAR, the Board will discontinue use of the inaccurate descriptor. Beginning with this opinion, and in those hereafter, the Board will label the portion of the opinion describing such changes as “Additional Technical Changes Authorized by Section 7.2(a).”
 

DISCUSSION
September 17, 1999: Revisions to the Unregulated Contaminant Monitoring Regulation for Public Water


 
Federal Action
 
The Safe Drinking Water Act (SDWA)(42 USC §§ 300f et seq. (1998)), as amended in 1996, requires the USEPA to establish criteria for a program to monitor for unregulated contaminants and, by August, 1999 to publish a list of contaminants to be monitored. The USEPA promulgated the Unregulated Contaminant Monitoring Regulation (UMCR) for Public Water Systems (PWSs), which significantly revises the existing regulations for unregulated contaminant monitoring. The amendments include a list of contaminants to monitor for, procedures for selecting a nationwide representative sample of small systems that will be required to monitor, and the frequency and schedule for monitoring, the sampling points, and the approved analytical methods for testing. The USEPA adopted the amendments under Section 1445(a) of SDWA (42 USC §§ 300j-4 (1998)).
 

Amendments to Board Rules

 The Board proposed incorporating the bulk of these amendments into its rules by adding Sections 611.511, 611.512, and 611.Appendix I. However, as a result of the public comments of the USEPA and the Agency, the Board is not including these amendments into this final rulemaking. The adoption of the unregulated contaminant monitoring program is not necessary for State primacy. For a more detailed discussion on the reasoning behind the omission of the unregulated contaminant monitoring program, see the “Public Comments” section below.


December 1, 1999: Revisions to National Primary and Secondary Drinking Water Regulations: Analytical Methods for Chemical and Microbiological Contaminants and Revisions to Laboratory Certification Requirements.
 

Federal Action
 
 The USEPA approved the use of updated versions of 25 American Society for Testing and Materials (ASTM), 54 Standard Methods for Examination of Water and Wastewater Methods (Standard Methods), and 13 USEPA analytical methods (USEPA Methods) for compliance determinations of chemical contaminants in drinking water. At the same time, the USEPA withdrew approval of 13 previous versions of the USEPA Methods. The USEPA also approved the use of a new medium and 2 new methods for simultaneous determination of total coliforms and E. coli. The USEPA also approved new methods of determination for lead, magnesium, and acid herbicides. The USEPA made several technical corrections to existing regulations.
 
Amendments to Board Rules
 
 The Board is amending its regulations for coliform sampling in Section 611.526, and methods incorporated by reference in Section 611.102. In Section 611.526 microbiological monitoring analytical methods, the Board adds tests set forth under the Standard Methods 19th edition. The Board also adds the E*Colite® Test (Charm Sciences, Inc.) and the m-ColiBlue24® Test (Hatch Company).
 
 The Board is amending regulations incorporated by reference for inorganic chemical sampling and analytical requirements in Section 611.102. The Board is amending its regulations for analytical methods or organic chemical contaminants in Section 611.645 and regulations incorporated by reference in Section 611.102. In Section 611.645 the Board is adding analytical methods that the USEPA added. The Board is also amending its regulations for volatile organic chemicals in Section 611.646 and regulations incorporated by reference in Section 611.102. The Board amends Section 611.531 to include the Standard Methods 19th edition.
 
 The Board amends Section 611.490 to require measurements for alkalinity, calcium, conductivity, disinfectant residual, orthophosphate, and silica to be performed by a certified operator under 35 Ill. Adm. Code 603.103.
 

Additional Technical Changes Authorized by Section 7.2(a)
 

 The Board is updating all C.F.R. citations in the affected sections of this rulemaking to the 1999 version. The Board is also amending Section 611.310(a) and the Section 611.310(c) Board Note to correct any ambiguity in the regulations for the purpose of avoiding confusion to the regulated community. Section 611.310 is applicable to all public water systems. The Board is also making numerous technical changes suggested by JCAR, the USEPA, and the Agency.
 
 In PC 1, JCAR submitted a line numbered version of the proposed rule, as it appeared in the Illinois Register. Changes in the proposed rule that were made by JCAR prior to publication in the Illinois Register were indicated in an accompanying green cover sheet. JCAR highlighted various minor technicalities, formatting discrepancies, and misspellings that were corrected by JCAR prior to publication. Also, JCAR indicated that it had struck “µg” and had added “mg” four times in Section 611.526(f). These changes to the regulations were made in error. The Board does not strike the four instances of “µg” currently on file in this final rule.
 
 In PC 2, JCAR submitted additional suggested changes in a line numbered version of the proposed rule. The Board made numerous minor technical changes suggested by JCAR in this final rule. The changes include adding and removing punctuation, spacing, capitalization, and spelling. The more substantive changes are indicated in the following table of revisions.
 
 In PC 3, the USEPA submitted comments concerning monitoring and analytical requirements. The Board has incorporated these suggestions. The USEPA also stated that since revisions to the unregulated contaminant monitoring regulations are not required for primacy, it did not review the related proposed amendments.
 
 In PC 4, the Agency requested that the proposed amendments implementing the unregulated contaminant monitoring program be omitted from the final rule. The Agency stated that Illinois is not required to adopt these rules in order to maintain primary enforcement authority for the SDWA. The Board proposed implementing the unregulated contaminant monitoring program by adding Sections 611.511, 611.512, and 611.Appendix I. The Board has omitted these sections in this final rule at the request of the Agency. The Agency also noted inconsistencies with respect to certain analytical methods. The Board has corrected any inconsistencies.

BOARD NOTE: Originally derived from 40 CFR 141.12(a)(1994), USEPA removed the last entry in this subsection and marked it reserved at 57 Fed. Reg. 31838 (July 17, 1992). USEPA added another listing of organic MCLs at 40 CFR 141.61 (1994). Heptachlor, heptachlor epoxide, and 2,4-D appear in both this Section and in Section 611.311, with a different MCL in each Section. The heptachlor, heptachlor epoxide, and 2,4-D MCLs in this Section are Illinois limitations that are more stringent than the federal requirements. However, detection of these contaminants or violation of their federally-derived revised Section 611.311 MCLs imposes more stringent monitoring, reporting, and notice requirements.
 
b) Chlorophenoxys:    
  2,4-D 0.01
*

BOARD NOTE: Originally derived from 40 CFR 141.12(b) (1994), USEPA removed the last entry in this subsection and marked it reserved at 56 Fed. Reg. 3578 (Jan. 30, 1991). See the preceding Board Note regarding the dual listing of MCLs for 2,4-D.
 
c) TTHM 0.10
*
1) The MCL of 0.10 mg/L for TTHM applies to a Subpart B community water system that serves 10,000 or more persons, until December 31, 2001.

SUBPART L: MICROBIOLOGICAL MONITORING AND ANALYTICAL REQUIREMENTS

 


Section 611.526
Analytical Methodology
 
   
a)
The standard sample volume required for total coliform analysis, regardless of analytical method used, is 100 mL.
b)
Suppliers need only determine the presence or absence of total coliforms,; a determination of total coliform density is not required.
c)
Suppliers shall 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):
 
1) Multiple-TubeTotal Coliform Fermentation (MTF) Technique, as set forth in Standard Methods, 18th or 19th ed.: Methods 9221 A and B:
 
A) 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;
B) 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
 
C) No requirement exists to run the completed phase on 10 percent of all total coliform-positive confirmed tubes.
 
 
2) Total Coliform Membrane Filter (MF) Technique, as set forth in Standard Methods, 18th or 19th ed.: Methods 9222 A, B, and C.
3) Presence-Absence (P-A) Coliform Test, as set forth in: Standard Methods, 18th or 19th ed.: Method 9221 D:
  
A) No requirement exists to run the completed phase on 10 percent of all total coliform-positive confirmed tubes; and
B) Six-times formulation strength may be used if the medium is filter-sterilized rather than autoclaved.
   
4) ONPG-MUG test: Standard Methods, 18th or 19th ed.: Method 9223. (The ONPG-MUG test is also known as the Aautoanalysis Ccolilert Ssystem.).
5) Colisure Test (Autoanalysis Colilert System)from Millipore Corporation, incorporated by reference in Section 611.102. (The Colisure Test must be incubated for 28 hours before examining results. If an examination of the results at 28 hours is not convenient, then results may be examined at any time between 28 hours and 48 hoursmay 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.
 
6) E*Coliteâ Test (Charm Sciences, Inc.).
7) m-ColiBlue24â Test (Hatch Company).
   
d)
This subsection corresponds with 40 CFR 141.21(f)(4), which USEPA has marked "reserved". This statement maintains structural consistency with the federal regulations.
e)
Suppliers shall conduct fecal coliform analysis in accordance with the following procedure:
1) 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.
 
2) 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 a sterile forceps and carefully curl and insert the membrane into a tube of EC medium.; (Tthe 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.
 
 
3) EC medium is described in Standard Methods, 18th ed. and 19th ed.: Method 9221 E.
4) Suppliers need only determine the presence or absence of fecal coliforms,; a determination of fecal coliform density is not required.
  
f)
Suppliers shall conduct analysis of E. coli in accordance with one of the following analytical methods, incorporated by reference in Section 611.102:
1) 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
 
 
2) Nutrient agar supplemented with 100 µg/L MUG (final concentration). Nutrient agar is described in Standard Methods, 18th ed. or 19th ed.: Method 9221 B, at pages 9-47 to 9-48. This test is used to determine if a total coliform-positive sample, as determined by the MF technique or any other method in which a membrane filter is used, contains E. coli. Transfer the membrane filter containing a total coliform colony or colonies to nutrient agar supplemented with 100 µg/L MUG (final concentration). After incubating the agar plate at 35° Celsius for 4 hours, observe the colony or colonies under ultraviolet light (366-nm) in the dark for fluorescence. If fluorescence is visible, E. coli are present.
3) Minimal Medium ONPG-MUG (MMO-MUG) Test, as set forth in Section 611.­Appendix D. (The Autoanalysis ColiertColilert 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 6-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.
 
   
4) The Colisure Test (Autoanalysis Colilert System), from Millipore Corporation, incorporated by reference in Section 611.102.
5) The membrane filter method with MI agar.
6) The E*Coliteâ Test.
7) The m-ColiBlue24â Test.
  
g)
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.
h)
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 regulations.

Section 611.612  Monitoring Requirements for Old Inorganic MCLs
 

 
a) Analyses for the purpose of determining compliance with the old inorganic MCLs of Section 611.300 are required as follows:
  
1) Analyses for all CWSs utilizing surface water sources must be repeated at yearly intervals.
2) Analyses for all CWSs utilizing only groundwater sources must be repeated at three-year intervals.
3) This subsection (a)(3) corresponds with 40 CFR 141.23(1)(3) (19941999), which requires monitoring for the repealed old MCL for nitrate at a frequency specified by the state. The Board has followed the U.S. EPAUSEPA lead and repealed that old MCL. This statement maintains structural consistency with U.S. EPAUSEPA rules.
 
4) This subsection (a)(4) corresponds with 40 CFR 141.23(1)(4) (19941999), which authorizes the state to determine compliance and initiate enforcement action. This authority exists through the authorization of the Act, not through federal rules. This statement maintains structural consistency with U.S. EPAUSEPA rules.
      
b) If the result of an analysis made under subsection (a) of this Section above indicates that the level of any contaminant listed in Section 611.300 exceeds the old MCL, the supplier shall report to the Agency within 7 days and initiate three additional analyses at the same sampling point within one month.
c) When the average of four analyses made pursuant to subsection (b) of this Section above, rounded to the same number of significant figures as the old MCL for the substance in question, exceeds the old MCL, the supplier shall notify the Agency and give notice to the public pursuant to Subpart T 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.
d) This subsection corresponds with 40 CFR 141.23(o) (19941999), which pertains to monitoring for the repealed old MCL for nitrate. The Board has followed the U.S. EPAUSEPA action and repealed that old MCL. This statement maintains structural consistency with U.S. EPAUSEPA rules.
e) This subsection corresponds with 40 CFR 141.23(p) (19941999), which pertains to the use of existing data up until a date long since expired. The Board did not adopt the original provision in R88-26. This statement maintains structural consistency with U.S. EPAUSEPA rules.
f) 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.
1) Fluoride: The methods specified in Section 611.611(c) shall apply for the purposes of this Section.

BOARD NOTE: The provisions of subsections (a) through (f) of this Section above derive from 40 CFR 141.23(l) through (p) (19941999), as amended at 59 Fed. Reg. 62466 (Dec. 5, 1994). USEPAU.S. EPA removed and reserved 40 CFR 141.23(q) (formerly 40 CFR 141.23(f)) at 59 Fed. Reg. 62466 (Dec. 5, 1994). Subsection (f)(2) of this Section above relates to a contaminant for which USEPAU.S. EPA specifies an MCL, but for which it repealed the analytical method. Subsections (f)(2) through (f)(4) of this Sectionabove relate exclusively to additional state requirements. The Board retained subsections (f)(1), (f)(3), and (f)(4) of this Section to set forth methods for the inorganic contaminants for which there is a state-only MCL. The methods specified are those set forth in 40 CFR 143.4(b) (1999), as amended at 59 Fed. Reg. 62471 (Dec. 5, 1994), for secondary MCLs. The predecessor to subsections (a) through (e) of this Sectionabove were formerly codified as Section 611.601. The predecessor to subsection (f) of this Sectionabove was formerly codified as Section 611.606.

BOARD NOTE: Derived from 40 CFR 141.24(f)(7), (f)(11), (f)(14)(i), and (f)(20) (19941999). This is a "trigger level" for Phase I, Phase II, and Phase V VOCs inasmuch as it prompts further action. The use of the term "detect" in this sectionSection is not intended to include any analytical capability of quantifying lower levels of any contaminant, or the "method detection limit". Note, however, that certain language at the end of federal paragraph (f)(20) is capable of meaning that the "method detection limit" is used to derive the "detection limit". The Board has chosen to disregard that language at the end of paragraph (f)(20) in favor of the more direct language of paragraphs (f)(7) and (f)(11).
"Method detection limit", as used in subsections (q) and (t) of this Sectionbelow means the minimum concentration of a substance that can be measured and reported with 99 percent confidence that the analyte concentration is greater than zero and is determined from analysis of a sample in a given matrix containing the analyte.
BOARD NOTE: Derived from 40 CFR 136, Appendix B (19941999). The method detection limit is determined by the procedure set forth in 40 CFR 136, Appendix B. See subsection (t) of this Sectionbelow.
b)
Required sampling. Each supplier shall take a minimum of one sample at each sampling point at the times required in subsection (u) of this Sectionbelow.
c)
Sampling points.
1) Sampling points for GWSs. Unless otherwise provided by SEP, a GWS supplier shall take at least one sample from each of the following points: each entry point that is representative of each well after treatment.
 
 
2) Sampling points for SWSs and mixed systems. Unless otherwise provided by SEP, a SWS or mixed system supplier shall sample from each of the following points:
A) Each entry point after treatment; or
 
B) Points in the distribution system that are representative of each source.
 
3) The supplier shall take each sample at the same sampling point unless the Agency has granted a SEP that designates another location as more representative of each source, or treatment plant, or within the distribution system.
 
4) If a system draws water from more than one source, and the sources are combined before distribution, the supplier shall sample at an entry point during periods of normal operating conditions when water is representative of all sources being used.
BOARD NOTE: Subsections (b) and (c) of this Sectionabove derived from 40 CFR 141.24(f)(1) through (f)(3) (19941999).
     
d)
Each CWS and NTNCWS supplier shall take four consecutive quarterly samples for each of the Phase I VOCs, excluding vinyl chloride, and Phase II VOCs during each compliance period, beginning in the compliance period starting in the initial compliance period.
e)
Reduction to annual monitoring frequency. If the initial monitoring for the Phase I, Phase II, and Phase V VOCs as allowed in subsection (r)(1) of this Sectionbelow has been completed by December 31, 1992, and the supplier did not detect any of the Phase I VOCs, including vinyl chloride, Phase II, or Phase V VOCs, then the supplier shall take one sample annually beginning in the initial compliance period.
f)
GWS reduction to triennial monitoring frequency. After a minimum of three years of annual sampling, GWS suppliers that have not previously detected any of the Phase I VOCs, including vinyl chloride, Phase II, or Phase V VOCs, shall take one sample during each three-year compliance period.
g)
A CWS or NTNCWS supplier that has completed the initial round of monitoring required by subsection (d) of this Sectionabove and which did not detect any of the Phase I VOCs, including vinyl chloride, Phase II, and Phase V VOCs, may apply to the Agency for a SEP pursuant to Section 611.110 that releases it from the requirements of subsection (e) or (f) of this Sectionabove. A supplier that serves fewer than 3300 service connections may apply to the Agency for a SEP pursuant to Section 611.110 that releases it from the requirements of subsection (d) of this Sectionabove as to 1,2,4-tri­chloro­benzene.
BOARD NOTE: Derived from 40 CFR 141.24(f)(7) and (f)(10) (19941999), and the discussion at 57 Fed. Reg. 31825 (July 17, 1992). Provisions concerning the term of the waiver appear below in subsections (i) and (j) of this Sectionbelow. The definition of "detect", parenthetically added to the federal counterpart paragraph, is in subsection (a) of this Sectionabove.
h)
Vulnerability Assessment. The Agency shall consider the factors of Section 611.110(e) in granting a SEP from the requirements of subsections (d), (e), or (f) of this Sectionabove sought pursuant to subsection (g) of this Sectionabove.
i)
A SEP issued to a GWS pursuant to subsection (g) of this Sectionabove is for a maximum of six years, except that a SEP as to the subsection (d) of this Sectionabove monitoring for 1,2,4-tri­chloro­benzene shall apply only to the initial round of monitoring. As a condition of a SEP, except as to a SEP from the initial round of subsection (d) of this Sectionabove monitoring for 1,2,4-tri­chloro­benzene, the supplier shall, within 30 months after the beginning of the period for which the waiver was issued, reconfirm its vulnerability assessment required by subsection (h) of this Sectionabove and submitted pursuant to subsection (g) of this Sectionabove, by taking one sample at each sampling point and reapplying for a SEP pursuant to subsection (g) of this Sectionabove. Based on this application, the Agency shall either:
 
1) If it determines that the PWS meets the standard of Section 611.610(e), issue a SEP that reconfirms the prior SEP for the remaining three-year compliance period of the six-year maximum term; or,
2) Issue a new SEP requiring the supplier to sample annually.
BOARD NOTE: This provision does not apply to SWSs and mixed systems.
 
j)
Special considerations for SEPs for SWSs and mixed systems.
 
1) The Agency must determine that a SWS is not vulnerable before issuing a SEP pursuant to a SWS supplier. A SEP issued to a SWS or mixed system supplier pursuant to subsection (g) of this Sectionabove is for a maximum of one compliance period; and
2) The Agency may require, as a condition to a SEP issued to a SWS or mixed supplier, that the supplier take such samples for Phase I, Phase II, and Phase V VOCs at such a frequency as the Agency determines are necessary, based on the vulnerability assessment.
BOARD NOTE: There is a great degree of similarity between 40 CFR 141.24(f)(7), the provision applicable to GWSs, and 40 CFR 141.24(f)(10), the provision for SWSs. The Board has consolidated the common requirements of both paragraphs into subsection (g) of this Sectionabove. Subsection (j) of this Sectionabove represents the elements unique to SWSs and mixed systems, and subsection (i) of this Sectionabove relates to GWSs. Although 40 CFR 141.24(f)(7) and (f)(10) are silent as to mixed systems, the Board has included mixed systems with SWSs because this best follows the federal scheme for all other contaminants.
k)
If one of the Phase I VOCs, excluding vinyl chloride, Phase II, or Phase V VOCs is detected in any sample, then:
   
1) The supplier shall monitor quarterly for that contaminant at each sampling point that resulted in a detection.
2) Annual monitoring shall be required.
A) The Agency shall grant a SEP pursuant to Section 611.110 that allows a supplier to reduce the monitoring frequency to annually at a sampling point if it determines that the sampling point is reliably and consistently below the MCL.
 
 
B) A request for a SEP must include the following minimal information:
 
i) For a GWS, two quarterly samples.
ii) For a SWS or mixed system, four quarterly samples.
 
C) In issuing a SEP, the Agency shall specify the level of the contaminant upon which the "reliably and consistently" determination was based. All SEPs that allow less frequent monitoring based on an Agency "reliably and consistently" determination shall include a condition requiring the supplier to resume quarterly monitoring pursuant to subsection (k)(1) of this Sectionabove if it violates the MCL specified by Section 611.311.
 
3) Suppliers that monitor annually shall monitor during the quarter(s) that previously yielded the highest analytical result.
 
  
4) Suppliers that do not detect a contaminant at a sampling point in three consecutive annual samples may apply to the Agency for a SEP pursuant to Section 611.110 that allows it to discontinue monitoring for that contaminant at that point, as specified in subsection (g) of this Sectionabove.
5) A GWS supplier that has detected one or more of the two-carbon contaminants listed in subsection (k)(5)(A) of this Sectionbelow shall monitor quarterly for vinyl chloride as described in subsection (k)(5)(B) of this Sectionbelow, subject to the limitation of subsection (k)(5)(C) of this Sectionbelow.
 
A) Two-carbon contaminants (Phase I or II VOC):
 
1,2-Dichloroethane (Phase I)
1,1-Dichloroethylene (Phase I)
cis-1,2-Dichloroethylene (Phase II)
trans-1,2-Dichloroethylene (Phase II)
Tetrachloroethylene (Phase II)
1,1,1-Trichloroethylene (Phase I)
Trichloroethylene (Phase I)
B) The supplier shall sample quarterly for vinyl chloride at each sampling point at which it detected one or more of the two-carbon contaminants listed in subsection (k)(5)(A) of this Sectionabove.
 
C) The Agency shall grant a SEP pursuant to Section 611.110 that allows the supplier to reduce the monitoring frequency for vinyl chloride at any sampling point to once in each three-year compliance period if it determines that the supplier has not detected vinyl chloride in the first sample required by subsection (k)(5)(B) of this Sectionabove.
  
l)
Quarterly monitoring following MCL violations.
1) Suppliers that violate an MCL for one of the Phase I VOCs, including vinyl chloride, Phase II, or Phase V VOCs, as determined by subsection (o) of this Sectionbelow, shall monitor quarterly for that contaminant, at the sampling point where the violation occurred, beginning the next quarter after the violation.
 
 
2) Annual monitoring.
A) The Agency shall grant a SEP pursuant to Section 611.110 that allows a supplier to reduce the monitoring frequency to annually if it determines that the sampling point is reliably and consistently below the MCL.
 
B) A request for a SEP must include the following minimal information: four quarterly samples.
 
C) In issuing a SEP, the Agency shall specify the level of the contaminant upon which the "reliably and consistently" determination was based. All SEPs that allow less frequent monitoring based on an Agency "reliably and consistently" determination shall include a condition requiring the supplier to resume quarterly monitoring pursuant to subsection (l)(1) of this Sectionabove if it violates the MCL specified by Section 611.311.
 
D) The supplier shall monitor during the quarter(s) that previously yielded the highest analytical result.
  
m)
Confirmation samples. The Agency may issue a SEP pursuant to Section 610.110 to require a supplier to use a confirmation sample for results that it finds dubious for whatever reason. The Agency must state its reasons for issuing the SEP if the SEP is Agency-initiated.
1) If a supplier detects any of the Phase I, Phase II, or Phase V VOCs in a sample, the supplier shall take a confirmation sample as soon as possible, but no later than 14 days after the supplier receives notice of the detection.
 
2) Averaging is as specified in subsection (o) of this Sectionbelow.
 
3) The Agency shall delete the original or confirmation sample if it determines that a sampling error occurred, in which case the confirmation sample will replace the original or confirmation sample.
   
n)
This subsection corresponds with 40 CFR 141.24(f)(14), an optional USEPA provision relating to compositing of samples that USEPA does not require for state programs. This statement maintains structural consistency with USEPA rules.
o)
Compliance with the MCLs for the Phase I, Phase II, and Phase V VOCs must be determined based on the analytical results obtained at each sampling point.
 
1) For suppliers that conduct monitoring at a frequency greater than annual, compliance is determined by a running annual average of all samples taken at each sampling point.
A) If the annual average of any sampling point is greater than the MCL, then the supplier is out of compliance.
 
B) If the initial sample or a subsequent sample would cause the annual average to exceed the MCL, then the supplier is out of compliance immediately.
 
C) Any samples below the detection limit shall be deemed as zero for purposes of determining the annual average.
 
 
2) If monitoring is conducted annually, or less frequently, the supplier is out of compliance if the level of a contaminant at any sampling point is greater than the MCL. If a confirmation sample is taken, the determination of compliance is based on the average of two samples.
3) When the portion of the distribution system that is out of compliance is separable from other parts of the distribution system and has no interconnections, the supplier may issue the public notice required by Subpart T of this Part only to persons served by that portion of the distribution system that is not in compliance.
   
p)
This provision corresponds with 40 CFR 141.24(f)(16) (19941999), which USEPA removed and reserved at 59 Fed. Reg. 62468 (Dec. 5, 1994). This statement maintains structural consistency with the federal regulations.
q)
Analysis under this Section must only be conducted by laboratories that have received certification by USEPA or the Agency according to the following conditions:
 
1) To receive certification to conduct analyses for the Phase I VOCs, excluding vinyl chloride, Phase II VOCs, and Phase V VOCs, the laboratory must:

B) Achieve the quantitative acceptance limits under subsections (q)(1)(C) and (q)(1)(D) of this Sectionbelow for at least 80 percent of the Phase I VOCs, excluding vinyl chloride, Phase II VOCs, except vinyl chloride, or Phase V VOCs;
C) Achieve quantitative results on the analyses performed under subsection (q)(1)(A) of this Sectionabove that are within ± 20 percent of the actual amount of the substances in the performance evaluation sample when the actual amount is greater than or equal to 0.010 mg/L;
D) Achieve quantitative results on the analyses performed under subsection (q)(1)(A) of this Sectionabove that are within ± 40 percent of the actual amount of the substances in the performance evaluation sample when the actual amount is less than 0.010 mg/L; and
 
E) Achieve a method detection limit of 0.0005 mg/L, according to the procedures in 40 CFR 136, appendix B, incorporated by reference in Section 611.102.
 
 
2) To receive certification to conduct analyses for vinyl chloride the laboratory must:
 
A) Analyze performance evaluation samples provided by the Agency pursuant to 35 Ill. Adm. Code 183.125(c)35 Ill. Adm. Code Part 186;
B) Achieve quantitative results on the analyses performed under subsection (q)(2)(A) of this Sectionabove that are within ± 40 percent of the actual amount of vinyl chloride in the performance evaluation sample;
 
 
C) Achieve a method detection limit of 0.0005 mg/L, according to the procedures in 40 CFR 136, appendix B, incorporated by reference in Section 611.102; and
D) Obtain certification pursuant to subsection (q)(1) of this Sectionabove for Phase I VOCs, excluding vinyl chloride, Phase II VOCs, and Phase V VOCs.
  
r)
Use of existing data.
 
1) The Agency shall allow the use of data collected after January 1, 1988 but prior to the effective date of this Section, pursuant to Agency sample request letters, if it determines that the data are generally consistent with the requirements of this Section.
2) The Agency shall grant a SEP pursuant to Section 611.110 that allows a supplier to monitor annually beginning in the initial compliance period if it determines that the supplier did not detect any Phase I, Phase II, or Phase V VOCs using existing data allowed pursuant to sub­sec­tion (r)(1) of this Sectionabove.
   
s)
The Agency shall, by SEP, increase the number of sampling points or the frequency of monitoring if it determines that it is necessary to detect variations within the PWS.
t)
Each laboratory certified for the analysis of Phase I, Phase II, or Phase V VOCs pursuant to subsection (q)(1) or (q)(2) of this Sectionabove shall:
1) Determine the method detection limit (MDL), as defined in 40 CFR 136, Appendix B, incorporated by reference in Section 611.102, at which it is capable of detecting the Phase I, Phase II, and Phase V VOCs; and,
 
2) Achieve an MDL for each Phase I, Phase II, and Phase V VOC that is less than or equal to 0.0005 mg/L.
 
u)
Each supplier shall monitor, within each compliance period, at the time designated by the Agency by SEP pursuant to Section 611.110.
BOARD NOTE: Derived from 40 CFR 141.24(f) (19941999).
