PUBLIC COMMENTS UNDER IC 13-14-9-4.5
IC 13-14-9-4.5 states that a board may not adopt a rule under IC 13-14-9 that is substantively different from the draft rule published under IC 13-14-9-4, until the board has conducted a third comment period that is at least 21 days long.
Because this proposed rule is not substantively different from the draft rule published on November 2, 2011, at DIN: 20111102-IR-327110667FDA, the Indiana Department of Environmental Management (IDEM) is not requesting additional comment on this proposed rule.

SUMMARY/RESPONSE TO COMMENTS FROM THE SECOND COMMENT PERIOD
IDEM requested public comment from November 2, 2011, through December 2, 2011, on IDEM's draft rule language.
No comments were received during the second comment period.

SUMMARY/RESPONSE TO COMMENTS RECEIVED AT THE FIRST PUBLIC HEARING
On May 23, 2012, the water pollution control board (board) conducted the first public hearing/board meeting concerning the development of amendments to drinking water standards at 327 IAC 8-2, ground water standards at 327 IAC 8-2.3, and disinfectants and disinfection rules at 327 IAC 8-2.5.
No comments were made at the first hearing.

1Because MDLs reported in EPA 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, that is, no sample digestion, will be higher. For direct analysis of cadmium and arsenic by Method 200.7, and arsenic by 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 and thallium by Method 200.9 and antimony by Method 3113 B unless multiple in-furnace depositions are made.
2If ultrasonic nebulization is used in the determination of arsenic by Method 200.7, 200.8, or 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 one hundred (100) μL of thirty percent (30%) hydrogen peroxide per one hundred (100) ml of solution. For direct analysis of arsenic with Method 200.8 using ultrasonic nebulization, samples and standards must contain one (1) mg/l of sodium hypochlorite.
3After January 1, 2006, analytical methods using the ICP-AES technology when analyzing for arsenic may not be used because the detection limits for these methods are eight-thousandths (0.008) mg/l or higher. This restriction means that the two (2) ICP-AES methods (Methods 200.7 and 3120 B) approved for use for the MCL of five-hundredths (0.05) mg/l may not be used for compliance determinations for the revised MCL of ten-thousandths (0.010) mg/l. However, prior to 2005, a system may have compliance samples analyzed with these less sensitive methods.

(b) Analysis under this section shall only be conducted by laboratories that have been certified by EPA or the commissioner. Laboratories may conduct sample analyses under provisional certification until January 1, 1996. To receive certification to conduct analyses for antimony, arsenic, asbestos, barium, beryllium, cadmium, chromium, cyanide, fluoride, mercury, nickel, nitrate, nitrite, selenium, and thallium, the laboratory must do the following:
(1) Successfully analyze PE samples provided by EPA, the commissioner, or by a third party with approval of the EPA or the commissioner, at least once a year.
(2) For each contaminant that has been included in the PE sample and for each method for which the laboratory desires certification achieve quantitative results on the analyses that are within the following acceptance limits:
Contaminant  Acceptance Limit 
Antimony  ±30% at >0.006 mg/l 
Arsenic1  ± 30% at > 0.003 mg/l 
Asbestos  2 standard deviations based on study statistics

Nitrite  ±15% at >0.4 mg/l 
Selenium  ±20% at >0.01 mg/l 
Thallium  ±30% at >0.002 mg/l 
1Acceptance limit effective January 1, 2006. Until then, limit should be two (2) standard deviations based on study statistics.

3Accurate determination of the chlorinated esters requires hydrolysis of the sample as described in Method 515.1, Method 515.2, Rev 1.1, Method 515.3, Method 555, and Method D 5317-93.

(b) Analysis for PCBs shall be conducted as follows using the methods in subsection (a):
(1) Each system that monitors for PCBs shall analyze each sample using either Method 505, Rev 2.1*, Method 508, Rev 3.1*, Method 508.1, Rev 2.0*, or Method 525.2, Rev 2.0*. Users of Method 505, Rev 2.1 may have more difficulty in achieving the required Arochlor detection limits than users of Method 508.1, Rev 2.0, Method 525.2, Rev 2.0 or Method 508, Rev 3.1.
(2) If PCBs (as one (1) of seven (7) arochlors) are detected, as designated as follows, in any sample analyzed using Method 505, Rev 2.1* or Method 508, Rev 3.1*, the system shall reanalyze the sample using Method 508A* to quantitate PCBs (as decachlorobiphenyl):

SECTION 4. 327 IAC 8-2-8.4 IS AMENDED TO READ AS FOLLOWS:

327 IAC 8-2-8.4 Analytical methods for microbiological contaminants

Authority: IC 13-13-5; IC 13-14-8-7; IC 13-14-9; IC 13-18-3; IC 13-18-16


Sec. 8.4. (a) A public water system shall analyze for microbiological contaminants as follows:
(1) The standard sample volume required for total coliform analysis, regardless of analytical method used, is one hundred (100) milliliters.
(2) Public water systems need only determine the presence or absence of total coliforms, and a determination of total coliform density is not required.
(3) Public water systems must conduct total coliform analyses in accordance with one (1) of the following analytical methods or with the alternative methods listed in Appendix A to Subpart C of 40 CFR 141:
(A) Total coliform fermentation technique1, 2, 3 as set forth in Method 9221A* and Method 9221B*.
(B) Total coliform membrane filter technique4 as set forth in Method 9222A*, Method 9222B*, and Method 9222C*.
(C) Presence-absence (P-A) coliform test3, 5 as set forth in Method 9221D*.
(D) ONPG-MUG test6 as set forth in Method 9223*.
(E) Colisure test*7.
(F) E*Colite® test*.
(G) m-ColiBlue24® test*.
(4) Public water systems must conduct fecal coliform analysis in accordance with the procedure in this subdivision. When the MTF technique or presence-absence (P-A) coliform test is used to test for total coliforms, shake the lactose-positive presumptive tube or P-A bottle vigorously and transfer the growth with a sterile three (3) millimeter loop or sterile applicator stick into brilliant green lactose bile broth and EC medium to determine the presence of total and fecal coliforms, respectively. For EPA-approved analytical methods which use a membrane filter, transfer the total coliform-positive culture by one (1) of the following methods:
(A) 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. (The laboratory may first remove a small portion of selected colonies for verification.)
(B) Alternately, the laboratory may 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 EC tubes to ensure adequate mixing and incubate in a water bath at forty-four and one-half (44.5) degrees Celsius, plus or minus two-tenths (0.2) degrees Celsius, for twenty-four (24) hours, plus or minus two (2) hours. Gas production of any amount in the inner fermentation tube of the EC medium indicates a positive fecal coliform test. The preparation of EC medium is described in Method 9221E, paragraph 1(a)*. Public water systems need only determine the presence or absence of fecal coliforms; a determination of fecal coliform density is not required.
(5) Public water systems must conduct analysis of Escherichia coli in accordance with one (1) of the following analytical methods or with the alternative methods listed in Appendix A to Subpart C of 40 CFR 141:
(A) EC medium supplemented with fifty (50) micrograms per milliliter of 4-methylumbelliferyl-beta-D-glucuronide (MUG) (final concentration). EC medium is described in Method 9221E, paragraph 1(a)*. MUG may be added to EC medium before autoclaving. EC medium supplemented with fifty (50) micrograms per milliliter of MUG is commercially available. At least ten (10) milliliters 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 shall be as specified in subdivision (4) for transferring a total coliform-positive culture to EC medium. Observe fluorescence with an ultraviolet light three hundred sixty-six (366) nanometers (preferably with a six (6) watt lamp) in the dark after incubating tube at forty-four and one-half (44.5) degrees Celsius, plus or minus two-tenths (0.2) degrees Celsius for twenty-four (24) hours, plus or minus two (2) hours.
(B) Nutrient agar supplemented with one hundred (100) micrograms per milliliter of MUG (final concentration). Nutrient agar is described in Method 9221E*. This test is used to determine if a total coliform-positive sample, as determined by the membrane filter technique or any other method in which a membrane filter is used contains E. coli. Transfer the membrane filter containing a total coliform colony(ies) colony or colonies to nutrient agar supplemented with one hundred (100) micrograms per milliliter (final concentration) of MUG. After incubating the agar plate at thirty-five (35) degrees Celsius for four (4) hours, observe the colony(ies) colony or colonies under ultraviolet light three hundred sixty-six (366) nanometers (preferably with a six (6) watt lamp) in the dark for fluorescence. If fluorescence is visible, E. coli are present.
(C) Minimal medium ONPG-MUG (MMO-MUG) test as described in the article "National Field Evaluation of a Defined Substrate Methods for the Simultaneous Detection of Total Coliforms and Escherichia coli from Drinking Water: Comparison with Presence-Absence Techniques*". If the MMO-MUG test is total coliform-positive after a twenty-four (24) hour incubation, test the medium for fluorescence with a three hundred sixty-six (366) nanometer ultraviolet light (preferably with a six (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 twenty-four (24) hours incubation, incubate the culture for an additional four (4) hours, but not to exceed twenty-eight (28) hours total, and again test the medium for fluorescence. The MMO-MUG test with hepes buffer in lieu of phosphate buffer is the only approved formulation for the detection of E. coli.
(D) The Colisure test*.
(E) The Membrane Filter Method with MI agar*.
(F) E*Colite® test*.
(G) m-ColiBlue24® test*.
(6) As an option to subdivision (5)(C), a system with a total coliform-positive, MUG-negative, MMO-MUG test may further analyze the culture for the presence of E. coli by transferring a one-tenth (0.1) milliliter, twenty-eight (28) hour MMO-MUG culture to EC medium plus MUG with a pipet. The formulation and incubation conditions of EC medium plus MUG and observation of the results are described in subdivision (5)(A).

(b) Response to a violation shall be as follows:
(1) A public water system which has exceeded the MCL for total coliforms in section 7 of this rule must report the violation to the commissioner no later than the end of the next business day after it learns of the violation and notify the public in accordance with 327 IAC 8-2.1-7 through 327 IAC 8-2.1-16.
(2) A public water system which has failed to comply with a coliform monitoring requirement, including the sanitary survey requirement, must report the monitoring violation to the commissioner within ten (10) days after the system discovers the violation, and notify the public in accordance with 327 IAC 8-2.1-7 through 327 IAC 8-2.1-16.

(c) The time from sample collection to initiation of analysis cannot exceed thirty (30) hours. Systems are encouraged but not required to hold samples below ten (10) degrees Celsius during transit.

(d) The agency strongly recommends that laboratories evaluate the false-positive and negative rates for the method or methods they use for monitoring total coliforms. The agency also encourages laboratories to establish false-positive and negative rates within their own laboratory and sample matrix (drinking water or source water or both) with the intent that if the method they choose has an unacceptable false-positive or negative rate, another method can be used. The agency suggests that laboratories perform these studies on a minimum of five percent (5%) of all total coliform-positive samples, except for those methods where verification or confirmation or both is already required, for example, the M-Endo and LES Endo Membrane Filter Tests, Standard Total Coliform Fermentation Technique, and Presence-Absence Coliform Test. Methods for establishing false-positive and negative-rates may be based on lactose fermentation, the rapid test for β-galactosidase and cytochrome oxidase, multi-test identification systems, or equivalent confirmation tests. False-positive and false-negative information is often available in published studies or from the manufacturer, or both.
1Lactose broth, as commercially available, may be used in lieu of lauryl tryptose broth, if the system conducts at least twenty-five (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 coliform, using lactose broth, is less than ten percent (10%).
2If inverted tubes are used to detect gas production, the media should cover these tubes at least one-half (1/2) to two-thirds (2/3) after the sample is added.
3No requirement exists to run the completed phase on ten percent (10%) of all total coliform-positive confirmed tubes.
4MI agar may also be used*.
5Six-times formulation strength may be used if the medium is filter-sterilized rather than autoclaved.
6The OPNG-MUG test is also known as the Autoanalysis Colilert System.
7The Colisure Test may be read after an incubation time of twenty-four (24) hours.
