Adopted Rule. Final Order.
ORDER OF THE BOARD (by R.C. Flemal):
By this order, the Board is adopting amendments to the Illinois drinking water regulations that are identical in substance to amendments adopted by the United States Environmental Protection Agency (USEPA) to the federal Safe Drinking Water Act (SDWA) (42 U.S.C. §§ 300f et seq. (1994)) drinking water regulations. The federal amendments included in this docket include those adopted by USEPA during the period between January 1, 2001 and June 30, 2001. The Board has also included a number of amendments prompted by comments from the Joint Committee on Administrative Rules (JCAR), the Illinois Environmental Protection Agency (Agency), and USEPA.
These adopted amendments are based on a proposal for public comment adopted by the Board on October 4, 2001, for which a Notice of Proposed Amendments appeared in the October 26, 2001 issue of the Illinois Register. The Board has made only non-substantive changes to the proposal to public comments.
Under Sections 7.2 and 17.5 of the Environmental Protection Act (Act) (415 ILCS 5/7.2 and 17.5 (2000)), the Board today adopts amendments to the Illinois regulations that are “identical in substance” to drinking water regulations that USEPA adopted 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) (1994)). The nominal timeframe of this docket includes federal SDWA amendments that USEPA adopted in the period January 1, 2001 through June 30, 2001.
Sections 7.2 and 17.5 provide for quick adoption 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. Section 17.5 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 (2000)) do not apply to the Board’s adoption of identical-in-substance regulations. The federal SDWA regulations are found at 40 C.F.R. 141 through 143.
This order supports an opinion that the Board also adopts today. The Board will file the adopted amendments with the Office of the Secretary of State without delay. The complete text of the adopted amendments follows.
I, Dorothy M. Gunn, Clerk of the Illinois Pollution Control Board, certify that the Board adopted the above order on February 21, 2002, by a vote of 7-0.

Code 101, if it determines that an alternative method identified by the supplier pursuant to subsection (a)(2) of this Section is technically feasible and would result in a significant reduction in TTHM. |
4) | Best available technology for TTHM reduction is as follows: |
A) | The use of chloramines as an alternative or supplemental disinfectant, |
B) | The use of chlorine dioxide as an alternative or supplemental disinfectant, or |
C) | Improved existing clarification for THM precursor reduction. |
BOARD NOTE: Subsection (a) derived from 40 CFR 142.60 (2000).
b) | Relief from the fluoride MCL. |
1) | In granting any variance or adjusted standard to a supplier that is a CWS from the maximum contaminant level for fluoride listed in Section 611.301(b), the Board will require application of the best available technology (BAT) identified at subsection (b)(4) of this Section for that constituent as a condition to the relief, unless the supplier has demonstrated through comprehensive engineering assessments that application of BAT is not technically appropriate and technically feasible for that supplier. |
2) | The Board will require the following as a condition for relief from the fluoride MCL where it does not require the application of BAT: |
A) | That the supplier continue to investigate the following methods as an alternative means of significantly reducing the level of fluoride, according to a definite schedule: |
i) | A modification of lime softening; |
ii) | Alum coagulation; |
iii) | Electrodialysis; |
iv) | Anion exchange resins; |
v) | Well field management; |
vi) | The use of alternative sources of raw water; and |
vii) | Regionalization, and |
B) | That the supplier report results of that investigation to the Agency. |

Code 101, if it determines that an alternative method identified by the supplier pursuant to subsection (b)(2) of this Section is technically feasible and would result in a significant reduction in fluoride. |
4) | Best available technology for fluoride reduction is as follows: |
A) | Activated alumina absorption centrally applied, and |
B) | Reverse osmosis centrally applied. |
BOARD NOTE: Subsection (b) derived from 40 CFR 142.61 (2000).
c) | Relief from an inorganic chemical contaminant, VOC, or SOC MCL. |
1) | In granting to a supplier that is a CWS or NTNCWS any variance or adjusted standard from the maximum contaminant levels for any VOC or SOC, listed in Section 611.311(a) or (c), or for any inorganic chemical contaminant, listed in Section 611.301, the supplier must have first applied the best available technology (BAT) identified at Section 611.311(b) (VOCs and SOCs) or Section 611.301(c) (inorganic chemical contaminants) for that constituent, unless the supplier has demonstrated through comprehensive engineering assessments that application of BAT would achieve only a minimal and insignificant reduction in the level of contaminant. |
BOARD NOTE: USEPA lists BAT for each SOC and VOC at 40 CFR 142.62(a) (2000), for the purposes of variances and exemptions (adjusted standards). That list is identical to the list at 40 CFR 141.61(b) (2000).
2) | The Board may require any of the following as a condition for relief from |
A) | That the supplier continue to investigate alternative means of compliance according to a definite schedule, and |
B) | That the supplier report results of that investigation to the Agency. |
3) | The Agency must petition the Board to reconsider or modify a variance or adjusted standard, pursuant to Subpart I of 35 Ill. Adm. Code 101, if it determines that an alternative method identified by the supplier pursuant to subsection (c)(2) of this Section is technically feasible. |

Section 611.609 | Determining Compliance |
Compliance with the MCLs of Sections Section 611.300 or 611.301 (as appropriate) must be determined based on the analytical result(s) results obtained at each sampling point.
a) | For suppliers that monitor at a frequency greater than annual, compliance with the MCLs for antimony, arsenic (effective January 22, 2004), asbestos, barium, beryllium, cadmium, chromium, cyanide, fluoride, mercury, nickel, selenium, or thallium is determined by a running annual average at each sampling point. Effective January 22, 2004, if a system fails to collect the required number of samples, compliance (average concentration) will be based on the total number of samples collected. |
1) | If the average at any sampling point is greater than the MCL, then the supplier is out of compliance. |
2) | If any one sample would cause the annual average to be exceeded, then the supplier is out of compliance immediately. |
3) | Any sample below the method detection limit must be calculated at zero for the purpose of determining the annual average. |
BOARD NOTE: The “method detection limit” is different from the “detection limit, ” as set forth in Section 611.600. The “method detection limit” is the level of contaminant that can be determined by a particular method with a 95 percent degree of confidence, as determined by the method outlined in 40 CFR 136, Appendix B, incorporated by reference at Section 611.102.
b) | For suppliers that monitor annually or less frequently, compliance with the MCLs for antimony, arsenic (effective January 22, 2004), asbestos, barium, beryllium, cadmium, chromium, cyanide, fluoride, mercury, nickel, selenium, or thallium is determined by the level of the contaminant at any sampling point. If |
c) | Compliance with the MCLs for nitrate and nitrite is determined based on one sample if the levels of these contaminants are below the MCLs. If the levels of nitrate or nitrite exceed the MCLs in the initial sample, Section 611.606 requires confirmation sampling, and compliance is determined based on the average of the initial and confirmation samples. |

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.
a) | 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 remain available for compliance monitoring until July 1, 1996. These methods will not be 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 Method 3120 B sample 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 Method 3113 B; and lead by ASTM Method D3559-90D unless multiple in-furnace depositions are made.
1) | Antimony: |

B) | Atomic absorption, hydride technique: ASTM Method D3697-92. |
C) | Atomic absorption, platform furnace technique: USEPA Environmental Metals Methods: Method 200.9. |
D) | Atomic absorption, furnace technique: Standard Methods, 18th or 19th ed.: Method 3113 B. |
2) | Arsenic: |
BOARD NOTE: If ultrasonic nebulization is used in the determination of arsenic by Methods 200.7, 200.8, or SM 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 L 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.
A) | 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 0.01 mg/L. However, prior to the 2005 through 2007 compliance period, a supplier may have compliance samples analyzed with these less sensitive methods.

SUBPART O: ORGANIC MONITORING AND ANALYTICAL REQUIREMENTS
Section 611.646 | Phase I, Phase II, and Phase V Volatile Organic Contaminants |
Monitoring of the Phase I, Phase II, and Phase V VOCs for the purpose of determining compliance with the MCL must be conducted as follows:
a) | Definitions. As used in this Section: |
“Detect” and “detection” means that the contaminant of interest is present at a level greater than or equal to the “detection limit.”
“Detection limit” means 0.0005 mg/L.
BOARD NOTE: Derived from 40 CFR 141.24(f)(7), (f)(11), (f)(14)(i), and (f)(20) (1999) (2000). 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 section 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 Section 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 (1999) (2000). The method detection limit is determined by the procedure set forth in 40 CFR 136, Appendix B. See subsection (t) of this Section.
b) Required sampling. Each supplier must take a minimum of one sample at each sampling point at the times required in subsection (u) of this Section.
c) | Sampling points. |
1) | Sampling points for |
2) | Sampling points for |
A) | Each entry point after treatment; or |
B) | Points in the distribution system that are representative of each source. |
3) | The supplier must take each sample at the same sampling point unless the Agency has granted |
4) | If a system draws water from more than one source, and the sources are combined before distribution, the supplier must 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 Section derived from 40 CFR 141.24(f)(1) through (f)(3) (1999) (2000).
d) | Each CWS and NTNCWS supplier must 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 Section has been completed by December 31, 1992, and the supplier did not detect any of the Phase I VOCs, including vinyl chloride |
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 |
g) | A CWS or NTNCWS supplier that has completed the initial round of monitoring required by subsection (d) of this Section and which did not detect any of the Phase I VOCs, including vinyl chloride |
BOARD NOTE: Derived from 40 CFR 141.24(f)(7) and (f)(10) (1999) (2000), and the discussion at 57 Fed. Reg. 31825 (July 17, 1992). Provisions concerning the term of the waiver appear in subsections (i) and (j) of this Section. The definition of “detect,” parenthetically added to the federal counterpart paragraph, is in subsection (a) of this Section.
h) | Vulnerability |
i) | |
1) | If it determines that the PWS meets the standard of Section 611.610(e), issue |
2) | Issue a new SEP requiring the supplier to sample annually. |
BOARD NOTE: Subsection (i) of this Section does not apply to SWSs an SWS and or mixed systems system supplier.
j) | Special considerations for |
1) | The Agency must determine that |
2) | The Agency may require, as a condition to |
BOARD NOTE: There is a great degree of similarity between 40 CFR 141.24(f)(7) (1999) (2000), the provision applicable to GWSs, and 40 CFR 141.24(f)(10) (1999) (2000), the provision for SWSs. The Board has consolidated the common requirements of both paragraphs into subsection (g) of this Section. Subsection (j) of this Section represents the elements unique to an SWSs and or mixed systems system, and subsection (i) of this Section relates to GWSs a GWS supplier. Although 40 CFR 141.24(f)(7) and (f)(10) are silent as to a mixed systems system supplier, the Board has included a mixed systems system supplier with SWSs an SWS supplier because this best follows the federal scheme for all other contaminants.
k) | If one of the Phase I VOCs, excluding vinyl chloride; a Phase II VOC; or a Phase V VOC is detected in any sample, then: |
1) | The supplier must monitor quarterly for that contaminant at each sampling point that resulted in a detection. |
2) | Annual monitoring. |
A) | The Agency must grant |
B) | A request for |
i) | For a GWS, two quarterly samples. |
ii) | For |
C) | In issuing |
3) | Suppliers that monitor annually must monitor during the quarters 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 |
5) | A GWS supplier that has detected one or more of the two-carbon contaminants listed in subsection (k)(5)(A) of this Section must monitor quarterly for vinyl chloride as described in subsection (k)(5)(B) of this Section, subject to the limitation of subsection (k)(5)(C) of this Section. |
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 must 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 Section. |
C) | The Agency must grant |
l) | Quarterly monitoring following MCL violations. |
1) | Suppliers that violate an MCL for one of the Phase I VOCs, including vinyl chloride |
2) | Annual monitoring. |
A) | The Agency must grant |
B) | A request for |
C) | In issuing |
D) | The supplier must monitor during the |
m) | Confirmation samples. The Agency may issue |
1) | If a supplier detects any of the Phase I, Phase II, or Phase V VOCs in a sample, the supplier must 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 Section. |
3) | The Agency must 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 (n) corresponds with 40 CFR 141.24(f)(14) |
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. Effective January 22, 2004, if one sampling point is in violation of an MCL, the system is in violation of the MCL. |
1) | Effective January 22, 2004, for a supplier that monitors more than once per year, compliance with the MCL is determined by a running annual average at each sampling point. |
2) | Effective January 22, 2004, a supplier that monitors annually or less frequently whose sample result exceeds the MCL must begin quarterly sampling. The system will not be considered in violation of the MCL until it has completed one year of quarterly sampling. |
3) | Effective January 22, 2004, if any sample result will cause the running annual average to exceed the MCL at any sampling point, the supplier is out of compliance with the MCL immediately. |
4) | Effective January 22, 2004, if a supplier fails to collect the required number of samples, compliance will be based on the total number of samples collected. |
5) | Effective January 22, 2004, if a sample result is less than the detection limit, zero will be used to calculate the annual average. |
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 must be deemed as zero for purposes of determining the annual average. |
p) | This subsection (p) corresponds with 40 CFR 141.24(f)(16) |

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 must monitor, within each compliance period, at the time designated by the Agency by SEP pursuant to Section 611.110. |
v) | A new system supplier or a supplier that uses a new source of water which begins operation after January 22, 2004 must demonstrate compliance with the MCL within a period of time specified by a permit issued by the Agency. The supplier must also comply with the initial sampling frequencies specified by the Agency to ensure the supplier can demonstrate compliance with the MCL. Routine and increased monitoring frequencies must be conducted in accordance with the requirements in this Section. |

Section 611.648 | Phase II, Phase IIB, and Phase V Synthetic Organic Contaminants |
Analysis of the Phase II, Phase IIB, and Phase V SOCs for the purposes of determining compliance with the MCL must be conducted as follows:
a) | Definitions. As used in this Section, the following terms will have the following meanings: |
“Detect” or “detection” means that the contaminant of interest is present at a level greater than or equal to the “detection limit.”.
“Detection limit” means the level of the contaminant of interest that is specified in subsection (r) of this Section.
BOARD NOTE: This is a “trigger level” for Phase II, Phase IIB, and Phase V SOCs inasmuch as it prompts further action. The use of the term “detect” or “detection” in this Section is not intended to include any analytical capability of quantifying lower levels of any contaminant, or the “method detection limit.”.
b) | Required sampling. Each supplier must take a minimum of one sample at each sampling point at the times required in subsection (q) of this Section. |
BOARD NOTE: USEPA stayed the effective date of the MCLs for aldicarb, aldicarb sulfone, and aldicarb sulfoxide at 57 Fed. Reg. 22178 (May 27, 1991). Section 611.311(c) includes this stay. However, despite the stay of the effectiveness of the MCLs for these three SOCs, suppliers must monitor for them.
c) | Sampling points. |
1) | Sampling points for GWSs. Unless otherwise provided by SEP, a GWS supplier must 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 |

B) | Points in the distribution system that are representative of each source. |
3) | The supplier must take each sample at the same sampling point unless the Agency has granted |
4) | If a system draws water from more than one source, and the sources are combined before distribution, the supplier must 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 Section derived from 40 CFR 141.24(h)(1) through (h)(3) (1999) (2000).
d) | Monitoring frequency. |
1) | Each CWS and NTNCWS supplier must take four consecutive quarterly samples for each of the Phase II, Phase IIB, and Phase V SOCs during each compliance period, beginning in the three-year compliance period starting in the initial compliance period. |
2) | Suppliers serving more than 3,300 persons that do not detect a contaminant in the initial compliance period must take a minimum of two quarterly samples in one year of each subsequent three-year compliance period. |
3) | Suppliers serving fewer than or equal to 3,300 persons that do not detect a contaminant in the initial compliance period must take a minimum of one sample during each subsequent three-year compliance period. |
e) | Reduction to annual monitoring frequency. A CWS or NTNCWS supplier may apply to the Agency for |
f) | Vulnerability assessment. The Agency must grant |
g) | If one of the Phase II, Phase IIB, or Phase V SOCs is detected in any sample, then the following must occur: |
1) | The supplier must monitor quarterly for the contaminant at each sampling point that resulted in a detection. |
2) | Annual monitoring. |
A) | A supplier may request that the Agency grant |
B) | A request for |

aldicarb sulfone
aldicarb sulfoxide
ii) | Second group: |
heptachlor
heptachlor epoxide.
h) | Quarterly monitoring following MCL violations. |
1) | Suppliers that violate an MCL for one of the Phase II, Phase IIB, or Phase V SOCs, as determined by subsection (k) of this Section, must monitor quarterly for that contaminant at the sampling point where the violation occurred, beginning the next quarter after the violation. |
2) | Annual monitoring. |
A) | A supplier may request that the Agency grant |
B) | A request for |
C) | The Agency must grant |
D) | In issuing the SEP, the Agency must specify the level of the contaminant upon which the “reliably and consistently” determination was based. |
E) | The supplier must monitor during the quarters that previously yielded the highest analytical result. |
i) | Confirmation samples. |

3) | The Agency must 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. |
j) | This subsection (j) corresponds with 40 CFR 141.24(h)(10), 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. |
k) | Compliance with the MCLs for the Phase II, Phase IIB, and Phase V SOCs shall be determined based on the analytical results obtained at each sampling point. Effective January 22, 2004, if one sampling point is in violation of an MCL, the supplier is in violation of the MCL. |
1) | Effective January 22, 2004, for a supplier that monitors more than once per year, compliance with the MCL is determined by a running annual average at each sampling point. |
2) | Effective January 22, 2004, a supplier that monitors annually or less frequently whose sample result exceeds the regulatory detection level as defined by subsection (r) of this Section must begin quarterly sampling. The system will not be considered in violation of the MCL until it has completed one year of quarterly sampling. |
3) | Effective January 22, 2004, if any sample result will cause the running annual average to exceed the MCL at any sampling point, the supplier is out of compliance with the MCL immediately. |
4) | Effective January 22, 2004, if a supplier fails to collect the required number of samples, compliance will be based on the total number of samples collected. |
5) | Effective January 22, 2004, if a sample result is less than the detection limit, zero will be used to calculate the annual average. |
6) | Until January 22, 2004, for a supplier that conducts 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 must be deemed as zero for purposes of determining the annual average. |
7) | Until January 22, 2004, if the supplier conducts monitoring 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. Until January 22, 2004, if a confirmation sample is taken, the determination of compliance is based on the average of two samples. |
l) | This subsection (l) corresponds with 40 CFR 141.24(h)(12) |
m) | Analysis for PCBs must be conducted as follows using the methods in Section 611.645: |

2) | If PCBs are detected in any sample analyzed using USEPA Organic Methods, |
3) | Compliance with the PCB MCL must be determined based upon the quantitative results of analyses using USEPA Organic Methods, Method 508A. |
n) | Use of existing data. |
1) | The Agency must allow the use of data collected after January 1, 1990 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 must grant |
o) | The Agency must issue |
BOARD NOTE: At 40 CFR 141.24(h)(15), USEPA uses the stated factors as non-limiting examples of circumstances that make additional monitoring necessary.
p) | This subsection (p) corresponds with 40 CFR 141.24(h)(16), a USEPA provision that the Board has not adopted because it reserves enforcement authority to the State and would serve no useful function as part of the State’s rules. This statement maintains structural consistency with USEPA rules. |
q) | Each supplier must monitor, within each compliance period, at the time designated by the Agency by SEP pursuant to Section 611.110. |
r) | “Detection” means greater than or equal to the following concentrations for each contaminant: |

Appendix G--Endnotes
1. Violations and other situations not listed in this table (e.g., reporting violations and failure to prepare Consumer Confidence Reports) do not require notice, unless otherwise determined by the Agency by a an SEP issued pursuant to Section 611.110. The Agency may, by a an SEP issued pursuant to Section 611.110, further require a more stringent public notice tier (e.g., Tier 1 instead of Tier 2 or Tier 2 instead of Tier 3) for specific violations and situations listed in this Appendix, as authorized under Sections 611.902(a) and 611.903(a).
2. Definition of the abbreviations used: “MCL” means maximum contaminant level, “MRDL” means maximum residual disinfectant level, and “TT” means treatment technique.
3. The term “violations of National Primary Drinking Water Regulations (NPDWR)” is used here to include violations of MCL, MRDL, treatment technique, monitoring, and testing procedure requirements.
4. Failure to test for fecal coliform or E. coli is a Tier 1 violation if testing is not done after any repeat sample tests positive for coliform. All other total coliform monitoring and testing procedure violations are Tier 3 violations.
5. A supplier that violates the turbidity MCL of 5 NTU based on an average of measurements over two consecutive days must consult with the Agency within 24 hours after learning of the violation. Based on this consultation, the Agency may subsequently decide to issue a an SEP pursuant to Section 611.110 that elevates the violation to a Tier 1 violation. If a system supplier is unable to make contact with the Agency in the 24-hour period, the violation is automatically elevated to a Tier 1 violation.
6. A supplier with a treatment technique violation involving a single exceedence of a maximum turbidity limit under the Surface Water Treatment Rule (SWTR) or the Interim Enhanced Surface Water Treatment Rule (IESWTR) are required to consult with the Agency within 24 hours after learning of the violation. Based on this consultation, the Agency may subsequently decide to issue a an SEP pursuant to Section 611.110 that elevates the violation to a Tier 1 violation. If a system supplier is unable to make contact with the Agency in the 24-hour period, the violation is automatically elevated to a Tier 1 violation.
7. Most of the requirements of the Interim Enhanced Surface Water Treatment Rule (63 Fed. Reg. 69477 (December 16, 1998)) (Sections 611.740-611.741, 611.743-611.744) become effective January 1, 2002 for a Subpart B supplier (surface water systems and groundwater systems under the direct influence of surface water) that serves at least 10,000 persons. However, Section 611.742 is currently effective. The Surface Water Treatment Rule (SWTR) remains in effect for systems a supplier serving at least 10,000 persons even after 2002; the Interim Enhanced Surface Water Treatment Rule adds additional requirements and does not in many cases supercede the SWTR.
8. The arsenic MCL citations are effective January 23, 2006. Until then, the citations are Sections 611.330(b) and 611.612(c).
9. The arsenic Tier 3 violation MCL citations are effective January 23, 2006. Until then, the citations are Sections 611.100, 611.101, and 611.612.
8. 10. Failure to take a confirmation sample within 24 hours for nitrate or nitrite after an initial sample exceeds the MCL is a Tier 1 violation. Other monitoring violations for nitrate are Tier 3.
9. 11. The uranium MCL Tier 2 violation citations are effective December 8, 2003 for all community water systems a CWS supplier.
10. 12. The uranium Tier 3 violation citations are effective December 8, 2000 for all community water systems a CWS supplier.
11. 13. A Subpart B community or non-transient non-community system supplier that serves 10,000 persons or more must comply with new DBP MCLs, disinfectant MRDLs, and related monitoring requirements beginning January 1, 2002. All other community and non-transient non-community systems must meet the MCLs and MRDLs beginning January 1, 2004. A Subpart B transient non-community system supplier serving 10,000 or more persons that uses chlorine dioxide as a disinfectant or oxidant must comply with the chlorine dioxide MRDL beginning January 1, 2002. A Subpart B transient non-community system supplier that serves fewer than 10,000 persons, which uses only groundwater not under the direct influence of surface water, and which uses chlorine dioxide as a disinfectant or oxidant must comply with the chlorine dioxide MRDL beginning January 1, 2004.
12. 14. Section 611.310 will no longer apply after January 1, 2004.
13. 15. Failure to monitor for chlorine dioxide at the entrance to the distribution system the day after exceeding the MRDL at the entrance to the distribution system is a Tier 2 violation.
14. 16. If any daily sample taken at the entrance to the distribution system exceeds the MRDL for chlorine dioxide and one or more samples taken in the distribution system the next day exceed the MRDL, Tier 1 notification is required. A failure to take the required samples in the distribution system after the MRDL is exceeded at the entry point also triggers Tier 1 notification.
15. 17. Some water suppliers must monitor for certain unregulated contaminants listed in Section 611.510.
16. 18. This citation refers to sections 1415 and 1416 of the federal Safe Drinking Water Act. sections 1415 and 1416 require that “a schedule prescribed . . . for a public water system granted relief equivalent to a SDWA section 1415 variance or a section 1416 exemption must require compliance by the system . . ..”
17. 19. In addition to sections 1415 and 1416 of the federal Safe Drinking Water Act, 40 CFR 142.307 specifies the items and schedule milestones that must be included in relief equivalent to a SDWA section 1415 small system variance. In granting any form of relief from an NPDWR, the Board will consider all applicable federal requirements for and limitations on the State’s ability to grant relief consistent with federal law.
18. 20. Other waterborne emergencies require a Tier 1 public notice under Section 611.902(a) for situations that do not meet the definition of a waterborne disease outbreak given in Section 611.101, but which still have the potential to have serious adverse effects on health as a result of short-term exposure. These could include outbreaks not related to treatment deficiencies, as well as situations that have the potential to cause outbreaks, such as failures or significant interruption in water treatment processes, natural disasters that disrupt the water supply or distribution system, chemical spills, or unexpected loading of possible pathogens into the source water.
