Regulation .03 Requirements for a Variance, Granting a Variance, and Public Hearings.Copy Citation

A.
The Approving Authority may grant to a supplier of water a variance or variances from certain requirements of this chapter. The requirements for obtaining variances are as follows:
(1)
The Approving Authority may issue a variance based on the condition that the supplier of water installs the best technology, treatment techniques, or other means, which the Approving Authority finds are available when taking costs into consideration, and based upon an evaluation that indicates that alternative sources of water are not reasonably available;
(2)
The Approving Authority may issue a variance to a supplier of water after documentation and consideration of findings set in 40 CFR §142.20;
(3)
The Approving Authority may issue to systems serving fewer than 10,000 persons a variance from a maximum contaminant level, or a treatment technique in accordance with 40 CFR §§142.301—142.313, Subpart K, except for microbial contaminants that are included in subparts H, P, S, T, W, and Y of the 40 CFR §141.
(4)
Variances from the treatment technique requirements of 40 CFR §141, Subpart H, may not be granted;
(5)
Variances from the total coliform and E. coli maximum contamination levels may not be granted; beginning April 1, 2016 the total coliform maximum contaminant level is no longer effective;
(6)
Variances from a maximum contaminant level for any synthetic organic chemical may only be granted if the:
(a)
Conditions of §A(4) of this regulation are met; and
(b)
Requirements of Regulation .03-1 of this chapter are met;
(7)
Except as otherwise provided in this regulation, variances from a maximum contaminant level may be granted if the Approving Authority finds that:
(a)
Characteristics of the raw water sources (which are reasonably available to the system) are such that the system cannot meet the requirements respecting the maximum contaminant levels of this regulation when application has been made of the best technology, treatment techniques, or other means, which the Approving Authority finds are generally available, taking costs into consideration; and
(b)
The granting of a variance does not result in an unreasonable risk to the health of persons served by the system;
(8)
Variances for a treatment technique other than treatment technique requirements of 40 CFR §141, Subpart H, may be granted if the Approving Authority finds that the supplier of water applying for the variance has demonstrated that the treatment technique is not necessary to protect the health of persons because of the nature of the raw water source of the system.
B.
A supplier of water may request the granting of a variance under this regulation for a public water system by submitting a request for a variance in writing to the Approving Authority. The written request shall include the following information:
(1)
The nature and duration of the variance requested.
(2)
Relevant analytical results of water quality sampling of the system, including tests conducted under the requirements of this regulation.
(3)
For any request made under §A(1) of this regulation:

Explanation in full and evidence that application of the best available treatment technology and techniques has been made.
(b)
Economic and legal factors relevant to ability or inability to comply.
(c)
Analytical results of alternate raw water quality relevant to the variance request.
(d)
A proposed compliance schedule, including the date each step toward compliance will be achieved. The schedule includes as a minimum the following dates:
(i)
The date by which arrangement for alternate raw water source or improvement of existing raw water source will be completed;
(ii)
The date of initiation of the connection of the alternate raw water source or improvement of existing raw water source; and
(iii)
The date by which final compliance is to be achieved.
(e)
A plan for the provision of safe drinking water in the case of an excessive rise in the contaminant level for which the variance is requested.

(4)
For a request made under §A(2) of this regulation, a statement that the supplier of water will perform monitoring and other reasonable requirements prescribed by the Approving Authority as a condition of the variance.
(5)
Other information, if any, believed to be pertinent by the applicant and other information required by the Approving Authority.
C.
The Approving Authority shall act on any variance request submitted under §B of this regulation within 90 days after receipt of the request and all necessary information. In addition, before acting on a request for a variance from:
(1)
An MCL, the Approving Authority shall consider such factors as the following:
(a)
The availability and effectiveness of treatment methods for the contaminant for which the variance is requested; and
(b)
Cost and other economic considerations such as implementing treatment, improving the quality of the source of water, or using an alternate source;
(2)
A required treatment technique, because this treatment is unnecessary to protect the public health, the Approving Authority shall consider such factors as the following:
(a)
Quality of the water source, including pertinent sources of pollution; and
(b)
Source protection measures employed by the supplier of water.
D.

Invalidation of a Fecal Indicator Positive Ground Water Source Sample.
(1)
A ground water supplier may obtain invalidation from the Approving Authority for a fecal indicator-positive ground water source sample collected under §D of this regulation only under the following conditions:
(a)
The supplier provides the Approving Authority with written notice from the laboratory that improper sample analysis occurred; or
(b)
The Approving Authority determines and documents in writing that there is substantial evidence that a fecal indicator-positive ground water source sample is not related to source water quality.
(2)
If the Approving Authority invalidates a fecal indicator-positive ground water source sample, the ground water supplier shall collect another source water sample under §D of this regulation within 24 hours of being notified by the Approving Authority of its invalidation decision and shall have it analyzed for the same fecal indicator using the analytical methods in §F of this regulation. The Approving Authority may extend the 24-hour time limit on a case-by-case basis if the supplier cannot collect the source water sample within 24 hours due to circumstances beyond its control. In the case of an extension, the Approving Authority shall specify how much time the supplier has to collect the sample.
H.
Sampling location.
(1)
Any ground water source sample required under §D of this regulation shall be collected at a location prior to any treatment of the ground water source unless the Approving Authority approves a sampling location after treatment.
(2)
If the system’s configuration does not allow for sampling at the well itself, the supplier may collect a sample at a location approved by the Approving Authority to meet the requirements of §D of this regulation if the sample is representative of the water quality of that well.
I.
New Sources. If directed by the Approving Authority, a ground water supplier that places a new ground water source into service after November 30, 2009, shall conduct assessment source water monitoring under §E of this regulation. If directed by the Approving Authority, the supplier shall begin monitoring before the ground water source is used to provide water to the public.
J.
Public Notification.
(1)
A ground water supplier with a ground water source sample collected under §D or E of this regulation that is fecal indicator-positive and that is not invalidated under §G of this regulation, including consecutive suppliers served by the ground water source, shall conduct public notification under Regulation .20B of this chapter.
(2)
Monitoring Violations. Failure to meet the requirements of §§D—I of this regulation is a monitoring violation and requires the ground water supplier to provide public notification under Regulation .20D of this chapter.

Regulation .11-3 Sanitary Survey Requirements for Community and Noncommunity Water Supply Systems.Copy Citation

A.
Public water systems that are required to regularly collect fewer than five total coliform samples a month shall undergo an initial sanitary survey by the Approving Authority. Community water supplies shall be surveyed before June 29, 1994. Noncommunity water supplies shall be surveyed before June 29, 1999.
B.
After the initial sanitary survey is completed, the systems in §A of this regulation shall undergo an additional sanitary survey every 5 years. Noncommunity water supply systems using only protected and disinfected ground water shall undergo a sanitary survey at least once every 10 years.
C.
Information collected in the course of developing a local wellhead protection program shall be considered for identifying sources of contamination within the delineated wellhead area. The Approving Authority shall review the results of each sanitary survey and determine if existing monitoring frequencies are adequate or if additional measures need to be taken to improve water quality.
D.
Sanitary surveys of ground water systems shall be conducted in accordance with the requirements of 40 CFR §§141.21 and 141.401.
(1)
Ground water suppliers shall provide the Approving Authority, at the request of the Approving Authority, any existing information that will enable the Approving Authority to conduct a sanitary survey.
(2)
Sanitary surveys, as conducted by the Approving Authority, shall include, but not be limited to, an onsite review of the water source or sources (identifying sources of contamination by using results of source water assessments or other relevant information where available), facilities, equipment, operation, maintenance, and monitoring compliance of a public water supplier to evaluate the adequacy of the system, its sources and operations and the distribution of safe drinking water.
(3)
The sanitary survey must include an evaluation of the applicable components that follow:
(a)
Source;
(b)
Treatment;
(c)
Distribution system;
(d)
Finished water storage;
(e)
Pumps, pump facilities, and controls;

Regulation .11-4 Microbiological Contaminant Monitoring and Reporting Requirements.Copy Citation

A.
Applicability.
(1)
This regulation applies to all public water systems.
(2)
Suppliers of water shall comply with the provisions of this regulation beginning April 1, 2016, unless otherwise specified.
(3)
Suppliers of water that fail to comply with the applicable requirements of 40 CFR §§141.851—141.861, are in violation of the regulation.
B.
Analytical Methods and Laboratory Certification.
(1)
Analytical Methodology.
(a)
The standard sample volume required for analysis, regardless of analytical method used, is 100 ml.
(b)
The samples shall be analyzed for the presence or absence of total coliforms and E. coli; a determination of density is not required.
(c)
The time from sample collection to initiation of test medium incubation may not exceed 30 hours. Suppliers are encouraged but not required to hold samples below 10° C during transit.
(d)
If drinking water having residual chlorine (measured as free, combined, or total chlorine) is to be analyzed, sufficient sodium thiosulfate (Na2S2O3) shall be added to the sample bottle before sterilization to neutralize any residual chlorine in the water sample.
(e)
Analyses shall be conducted for total coliform and E. coli analyses in accordance with an EPA approved analytical method, which is incorporated by reference.
(2)
Laboratory certification. Suppliers shall have all compliance samples required under this regulation analyzed by a laboratory certified by the EPA, or the Approving Authority to analyze drinking water samples. The laboratory used by the supplier shall be certified for each method, and associated contaminants used for compliance monitoring analyses under this regulation.
C.
General Monitoring Requirements for All Public Water Systems.
(1)
Sample Siting Plans.
(a)
No later than March 31, 2016, suppliers shall develop a written sample siting plan, which identifies sampling sites and includes a sample collection schedule and which shall be representative of water throughout the distribution system. These plans are subject to review by the Approving Authority and revision as needed. Suppliers shall collect total coliform samples according to the written sample siting plan. Monitoring required by this regulation may take place at a customer's premise, dedicated sampling station, or other designated compliance sampling location. Routine and repeat sample sites and any sampling points necessary to meet the requirements of Regulation .11-2 shall be included in the sampling plan.
(b)
Suppliers shall collect samples at regular time intervals throughout the month, except that suppliers that use only ground water and serve 4,900 or fewer people may collect all required samples on a single day if they are taken from different sites.
(c)
Suppliers shall take at least the minimum number of required samples even if the system has had an E. coli MCL violation or has exceeded the coliform treatment technique triggers in §I(1) of this regulation.
(d)
A supplier may conduct more compliance monitoring than is required by this regulation to investigate potential problems in the distribution system and use monitoring as a tool to assist in uncovering problems. A supplier may take more than the minimum number of required routine samples and shall include the results in calculating whether the coliform treatment technique trigger in §I(1)(a) of this regulation has been exceeded if the samples are taken in accordance with the existing sample siting plan and are representative of water throughout the distribution system.
(e)
Suppliers shall identify repeat monitoring locations in the sample siting plan according to the requirements of 40 CFR §141.853(a) which is incorporated by reference.
(2)
Special purpose samples. Special purpose samples, such as those taken to determine whether disinfection practices are sufficient following pipe placement, replacement, or repair, may not be used to determine whether the coliform treatment technique trigger has been exceeded. Repeat samples taken according to §H of this regulation are not considered special purpose samples, and shall be used to determine whether the coliform treatment technique trigger has been exceeded.
(3)
Invalidation of total coliform samples. A total coliformpositive sample invalidated under this section does not count toward meeting the minimum monitoring requirements of this regulation.
(a)
The Approving Authority may invalidate a total coliformpositive sample if the one of the following conditions are met:
(i)
The laboratory establishes that improper sample analysis caused the total coliform-positive result;
(ii)
The Approving Authority, on the basis of the results of repeat samples collected as required under §H of this regulation, determines that the total coliform-positive sample resulted from a domestic or other nondistribution system plumbing problem. The Approving Authority cannot invalidate a sample on the basis of repeat sample results unless all repeat sample(s) collected at a location other than the original tap are total coliform-negative; or
(iii)
The Approving Authority has substantial grounds to believe that a total coliform-positive result is due to a circumstance or condition that does not reflect water quality in the distribution system. In this case, the supplier shall still collect all repeat samples required under §H of this regulation, and use them to determine whether a coliform treatment technique trigger in §I of this regulation has been exceeded.
(b)
A laboratory shall invalidate a total coliform sample (unless total coliforms are detected) if the sample produces a turbid culture in the absence of gas production using an analytical method where gas formation is examined (e.g., the Multiple-Tube Fermentation Technique), produces a turbid culture in the absence of an acid reaction in the Presence-Absence (P-A) Coliform Test, or exhibits confluent growth or produces colonies too numerous to count with an analytical method using a membrane filter (e.g., Membrane Filter Technique). If a laboratory invalidates a sample because of such interference, the supplier shall collect another sample from the same location as the original sample within 24 hours of being notified of the interference problem, and have it analyzed for the presence of total coliforms. The supplier shall continue to re-sample within 24 hours and have the samples analyzed until it obtains a valid result. The Approving Authority may waive the 24-hour time limit on a case-by-case basis. Alternatively, the Approving Authority may implement criteria for waiving the 24-hoursampling time limit to use in lieu of case-by-case extensions.

In months when 1,000 or fewer people are served, the Approving Authority may reduce the monitoring frequency, in writing, to a frequency allowed under §D of this regulation for a similarly situated system that always serves 1,000 or fewer people, taking into account the provisions in §D(1)—(7).
H.
Repeat Monitoring and E. coli Requirements
(1)
Repeat Monitoring.
(a)
If a sample taken under §§D—G of this regulation is total coliform-positive, the supplier shall collect a set of repeat samples within 24 hours of being notified of the positive result. The supplier shall collect no fewer than three repeat samples for each total coliform-positive sample found. The Approving Authority may extend the 24-hour limit on a case-by-case basis if the supplier has a logistical problem in collecting the repeat samples within 24 hours that is beyond its control. Alternatively, the Approving Authority may implement criteria for the supplier to use in lieu of case-by-case extensions. In the case of an extension, the Approving Authority shall specify how much time the supplier has to collect the repeat samples. The Approving Authority cannot waive the requirement for a supplier to collect repeat samples in §H(a)—(c) of this regulation.
(b)
The supplier shall collect all repeat samples on the same day, except that the Approving Authority may allow a supplier with a single service connection to collect the required set of repeat samples over a 3-day period or to collect a larger volume repeat sample(s) in one or more sample containers of any size, as long as the total volume collected is at least 300 ml.
(c)
The supplier shall collect an additional set of repeat samples in the manner specified in §H(1)(a)—(c) of this regulation if one or more repeat samples in the current set of repeat samples is total coliform-positive. The supplier shall collect the additional set of repeat samples within 24 hours of being notified of the positive result, unless the Approving Authority extends the limit as provided in §H(1)(a) of this regulation. The supplier shall continue to collect additional sets of repeat samples until either total coliforms are not detected in one complete set of repeat samples or the supplier determines that a coliform treatment technique trigger specified in §I(1) of this regulation has been exceeded as a result of a repeat sample being total coliform-positive and notifies the Approving Authority. If a trigger identified in §I of this regulation is exceeded as a result of a routine sample being total coliform-positive, suppliers are required to conduct only one round of repeat monitoring for each total coliform-positive routine sample.
(d)
After a supplier collects a routine sample and before it learns the results of the analysis of that sample, if it collects another routine sample(s) from within five adjacent service connections of the initial sample, and the initial sample, after analysis, is found to contain total coliforms, then the supplier may count the subsequent sample(s) as a repeat sample instead of as a routine sample.
(e)
Results of all routine and repeat samples taken under §§D—G of this regulation not invalidated by the Approving Authority shall be used to determine whether a coliform treatment technique trigger specified in §I of this regulation has been exceeded.
(2)
Escherichia coli (E. coli) Testing.
(a)
If any routine or repeat sample is total coliform-positive, the supplier shall analyze that total coliform-positive culture medium to determine if E. coli are present. If E. coli are present, the supplier shall notify the Approving Authority by the end of the day when the supplier is notified of the test result, unless the supplier is notified of the result after the Approving Authority office is closed and the Approving Authority does not have either an after-hours phone line or an alternative notification procedure, in which case the supplier shall notify the Approving Authority before the end of the next business day.
(b)
The Approving Authority has the discretion to allow a supplier, on a case-by-case basis, to forgo E. coli testing on a total coliform-positive sample if that supplier assumes that the total coliform-positive sample is E. coli-positive. Accordingly, the supplier shall notify the Approving Authority as specified in §H(2)(a) of this regulation and the provisions of 40 CFR §141.63(c) apply.
I.

(b)
When conducting assessments, suppliers shall ensure that the assessor evaluates minimum elements that include review and identification of inadequacies in sample sites; sampling protocol; sample processing; atypical events that could affect distributed water quality or indicate that distributed water quality was impaired; changes in distribution system maintenance and operation that could affect distributed water quality (including water storage); source and treatment considerations that bear on distributed water quality, where appropriate (e.g., small ground water systems); and existing water quality monitoring data. The supplier shall conduct the assessment consistent with any Approving Authority directives that tailor specific assessment elements with respect to the size and type of the system and the size, type, and characteristics of the distribution system.
(3)
Level 1 Assessments. A supplier shall conduct a Level 1 assessment consistent with Approving Authority requirements if the system exceeds one of the treatment technique triggers in §I(1)(a) of this regulation.
(a)
The supplier shall complete a Level 1 assessment as soon as practical after any trigger in §I(1)(a) of this regulation. In the completed assessment form, the supplier shall describe sanitary defects detected, corrective actions completed, and a proposed timetable for any corrective actions not already completed. The assessment form may also note that no sanitary defects were identified. The supplier shall submit the completed Level 1 assessment form to the Approving Authority within 30 days after the supplier learns that it has exceeded a trigger.
(b)
If the Approving Authority reviews the completed Level 1 assessment and determines that the assessment is not sufficient (including any proposed timetable for any corrective actions not already completed), the Approving Authority shall consult with the supplier. If the Approving Authority requires revisions after consultation, the supplier shall submit a revised assessment form to the Approving Authority on an agreed-upon schedule not to exceed 30 days from the date of the consultation.
(c)
Upon completion and submission of the assessment form by the supplier, the Approving Authority shall determine if the supplier has identified a likely cause for the Level 1 trigger and, if so, establish if the supplier has corrected the problem, or has included a schedule acceptable to the Approving Authority for correcting the problem.
(4)
Level 2 Assessments. A supplier shall ensure that a Level 2 assessment consistent with Approving Authority requirements is conducted if the supplier exceeds one of the treatment technique triggers in §I(1)(b) of this regulation. The supplier shall comply with any expedited actions or additional actions required by the Approving Authority in the case of an E. coli MCL violation.
(a)
The supplier shall ensure that a Level 2 assessment is completed as soon as practical after any trigger in §I(1)(b) of this regulation. The supplier shall submit a completed Level 2 assessment form to the Approving Authority within 30 days after the supplier learns that it has exceeded a trigger. The assessment form shall describe sanitary defects detected, corrective actions completed, and a proposed timetable for any corrective actions not already completed.

(c)
If the Approving Authority reviews the completed Level 2 assessment and determines that the assessment is not sufficient (including any proposed timetable for any corrective actions not already completed), the Approving Authority shall consult with the supplier. If the Approving Authority requires revisions after consultation, the supplier shall submit a revised assessment form to the Approving Authority on an agreed-upon schedule not to exceed 30 days.
(d)
Upon completion and submission of the assessment form by the supplier, the Approving Authority shall determine if the supplier has identified a likely cause for the Level 2 trigger and determine whether the supplier has corrected the problem, or has included a schedule acceptable to the Approving Authority for correcting the problem.
(5)
Corrective Action. Suppliers shall correct sanitary defects found through either Level 1 or 2 assessments conducted under §I(2) of this regulation. For corrections not completed by the time of submission of the assessment form, the supplier shall complete the corrective action(s) in compliance with a timetable approved by the Approving Authority in consultation with the supplier. The supplier shall notify the Approving Authority when each scheduled corrective action is completed.
(6)
Consultation. At any time during the assessment or corrective action phase, either the water supplier or the Approving Authority may request a consultation with the other party to determine the appropriate actions to be taken. The supplier may consult with the Approving Authority on all relevant information that may impact on its ability to comply with a requirement of §I(6), including the method of accomplishment, an appropriate time frame, and other relevant information.

Regulation .13 Sampling Analysis: Gross Alpha Particle Activity, Radium-226, Radium-228, Uranium.Copy Citation

A.
This regulation applies to a community water system (CWS).
B.
Sampling Location. The supplier of water to a community water system shall:
(1)
Sample at every entry point to the distribution system that is representative of all sources being used (after this called a sampling point) under normal operating conditions; and
(2)
Take each sample at the same sampling point unless:
(a)
Conditions make another sampling point more representative of each source; or
(b)
The Approving Authority has designated a distribution system location.
C.
Initial Monitoring.
(1)
The supplier of water to an existing CWS shall conduct initial monitoring by December 31, 2007 in order to determine compliance with Regulation .09A of this chapter. The Approving Authority may require more frequent monitoring in the event of possible contamination or if changes in the distribution system or treatment processes occur that may increase the concentration of radioactivity in finished water.
(2)
The supplier of water to a new CWS or a CWS that uses a new source of water shall begin to conduct initial monitoring for the new source within the first quarter after initiating use of the source.
(3)
For systems without acceptable historical data, as defined in §C(4) of this regulation, the supplier of water shall collect four consecutive quarterly samples at all sampling points before December 31, 2007.
(4)
The Approving Authority may allow historical monitoring data collected at a sampling point, if designated as appropriate by the Approving Authority, to satisfy the initial monitoring requirements for that sampling point, for the following situations:
(a)
A CWS having only one entry point to the distribution system may use the monitoring data from the last compliance monitoring period beginning June 1, 2000 through December 8, 2003;
(b)
A CWS with multiple entry points and having appropriate historical monitoring data for each entry point to the distribution system may use the monitoring data from the last compliance monitoring period beginning June 1, 2000 through December 8, 2003; or
(c)
A CWS with historical monitoring data for a representative point in the distribution system may use the monitoring data from the last compliance monitoring period beginning June 1, 2000 through December 8, 2003, if:
(i)
The Approving Authority finds that the historical data satisfactorily demonstrate that each entry point to the distribution system is expected to be in compliance based upon the historical data and reasonable assumptions about the variability of contaminant levels between entry points; and
(ii)
The Approving Authority makes a written finding indicating how the data conforms to these requirements.
(5)
For gross alpha particle activity, uranium, radium-226, and radium-228 monitoring, the Approving Authority may waive the final 2 quarters of initial monitoring for a sampling point if the results of the samples from the previous 2 quarters are below the detection limit.
(6)
If the average of the initial monitoring results for a sampling point is above the maximum contaminant level (MCL), the supplier of water shall collect and analyze quarterly samples at that sampling point until the system has results from 4 consecutive quarters that are at or below the MCL, unless the supplier enters into another schedule as part of a formal compliance agreement with the Approving Authority.
D.
Reduced Monitoring.
(1)
The supplier of water may reduce the future frequency of monitoring for a contaminant from once every 3 years to once every 9 years at each sampling point, if the average of the initial monitoring results for each such contaminant is below the detection limit specified in 40 CFR §141.25, Table B.
(2)
The supplier of water may reduce the future frequency of monitoring for a contaminant from once every 3 years to once every 6 years at each sampling point, if:
(a)
For gross alpha particle activity or uranium, the average of the initial monitoring results are at or above the detection limit but at or below 1/2 the MCL; or
(b)
For combined radium-226 and radium-228, the average of the initial monitoring results is at or above the detection limit but at or below 1/2 the MCL.
(3)
The supplier of water shall collect and analyze at least one sample for a contaminant at each sampling point every 3 years if:
(a)
For gross alpha particle activity or uranium, the average of the initial monitoring results is above 1/2 the MCL but at or below the MCL; or
(b)
For combined radium-226 and radium-228, the average of the initial monitoring results is above 1/2 the MCL but at or below the MCL.
(4)
The supplier of water shall use the samples collected during the most recent reduced monitoring period to determine the monitoring frequency for subsequent monitoring periods. For example, if a system's sampling point is on a 9-year monitoring period, and the sample result is above 1/2 MCL, the next monitoring period for that sampling point is 3 years.
(5)
If a CWS has a monitoring result that exceeds the MCL while on reduced monitoring, the supplier of water shall collect and analyze quarterly samples at that sampling point until the system has results from 4 consecutive quarters that are below the MCL, unless the supplier of water enters into another schedule as part of a formal compliance agreement with the Approving Authority.
E.
Compositing.
(1)
To fulfill quarterly monitoring requirements for gross alpha particle activity, radium-226, radium-228, or uranium, a supplier of water may composite up to four consecutive quarterly samples from a single entry point if analysis is done within a year of the first sample.
(2)
The composited result shall be used as the average analytical result to determine compliance with the MCLs and the future monitoring frequency.
(3)
If the analytical result from the composited sample is greater than 1/2 MCL, the Approving Authority may direct the water supplier to take additional quarterly samples before allowing the system to sample under a reduced monitoring schedule.
F.
Substitutions.
(1)
If the measured gross alpha particle activity does not exceed 5 picocuries per liter (pCi/l), a gross alpha particle activity measurement may be substituted for the required radium-226 measurement.
(2)
If the measured gross alpha particle activity does not exceed 15 picocuries per liter (pCi/l), a gross alpha particle activity measurement may be substituted for the required uranium measurement.
(3)
If a supplier of water uses a gross alpha particle activity measurement instead of a radium-226 measurement, uranium measurement, or both, the gross alpha particle activity analytical result shall be used to determine the future monitoring frequency for radium-226, uranium, or both.
(4)
If the gross alpha particle activity result is less than detection, 1/2 the detection limit shall be used to determine compliance and the future monitoring frequency.
G.
Analyses conducted to determine compliance with this regulation shall be made in accordance with those methods specified in 40 CFR §141.25 (1989), which is incorporated by reference.
H.
Detection Limit.
(1)
For the purpose of monitoring radioactivity concentrations in drinking water, the required sensitivity of the radioanalysis is defined in terms of a detection limit. The detection limit shall be that concentration which can be measured with an accuracy of plus or minus 100 percent at the 95 percent confidence level (1.96 sigma where sigma is the standard deviation of the net counting rate of the sample).
(2)
To determine compliance with Regulation .09A(1) of this chapter, the detection limit may not exceed 1 pCi/liter. To determine compliance with Regulation .09A(2) of this chapter, the detection limit may not exceed 3 pCi/liter.
(3)
To determine compliance with Regulation .09B, the detection limit may not exceed the concentrations listed in Table A of this regulation.

A.
This regulation applies to a community water system (CWS). The Approving Authority may require more frequent monitoring than specified in Regulations .13 and .13-1 of this chapter, or may require confirmation samples at its discretion. The results of the initial and confirmation samples shall be averaged for use in compliance determinations.
B.
Suppliers of water shall monitor at the time designated by the Approving Authority during each compliance period.
C.
Compliance with Regulation .09 of this chapter shall be determined based on the analytical results obtained at each sampling point. If one sampling point is in violation of an MCL, the system is in violation of the MCL.
D.
For a CWS monitoring more than once per year:
(1)
Compliance with the MCL is determined by a running annual average at each sampling point;
(2)
If the average of any sampling point is greater than the MCL, the system is out of compliance with the MCL; and
(3)
If any sample result causes the running average to exceed the MCL at any sample point, the system is out of compliance with the MCL immediately.
E.
Suppliers of water shall include all samples taken and analyzed under the provisions of Regulations .13, .13-1, and .13-2 of this chapter in determining compliance, even if that number is greater than the minimum required.
F.
If a supplier of water does not collect all required samples when compliance is based on a running annual average of quarterly samples, compliance shall be based on the running average of the samples collected.
G.
If a sample result is less than the detection limit, zero will be used to calculate the annual average, unless a gross alpha particle activity is being used instead of radium-226, uranium, or both. If gross alpha particle activity is being used instead of radium-226, uranium, or both and if the gross alpha particle activity result is less than detection, 1/2 the detection limit shall be used to calculate the annual average.
H.
The Approving Authority may delete results of obvious sampling or analytical errors.
I.
If the MCL for radioactivity set forth in Regulation .09 of this chapter is exceeded, the operator of a CWS shall give notice to the Approving Authority as required by Regulation .19 of this chapter and to the public as required by Regulation .20 of this chapter.
J.
Suppliers of water may be eligible for variances or exemptions from the maximum contaminant levels for radionuclides based on criteria outlined in 40 CFR §142.65.
