Without addressing the system itself, we will always have drowning kids in our river. This parable was shared in the context of workforce development from our partners at CareerWise Colorado. The parable applies to other community issues: health care, transportation, and economic relief.
It is within this context that we urge extension of the deadline for the Paycheck Protection Program through December 31, Our businesses need the upstream support of the federal government as consumer confidence continues to build back and as local groups such as Vail Valley Partnership and Small Business Development Center focus on downstream impacts. That aid allowed between 1. Despite the breadth of this emergency aid, small businesses continue to struggle, especially minority-owned businesses.
The same report shows that minorities have a harder time accessing the capital needed to keep their businesses open. Legislation enacted last December helped target aid to small businesses that need help the most and the American Rescue Plan passed by the U.
House of Representatives last week goes even further by providing targeted aid for the restaurant industry and for shuttered venues, and by directing outreach and assistance to entrepreneurs in communities where minority-owned businesses are struggling.
All these steps need additional time for them to actually produce the desired result. Extending the PPP deadline through the end of this year will ensure that the segment of small businesses facing the greatest obstacles do not get left behind.

Subchapter C. General monitoring requirements. Alternative monitoring requirements may be established by the Department and may be implemented in lieu of monitoring requirements for a particular National Primary Drinking Water Regulation if the alternative monitoring requirements are in conformance with the Federal act and regulations.
The monitoring requirements shall be applied as follows: 1 Performance monitoring for filtration and disinfection. II For systems that do not operate continuously, at start-up, at least once every 4 hours that the system is in operation, and also prior to shutting down the plant, except as provided in clause B.
B May substitute continuous turbidity monitoring and recording for grab sample monitoring and manual recording until August 19, , if it validates the continuous measurement for accuracy on a regular basis using a procedure specified by the manufacturer.
At a minimum, calibration with an EPA-approved primary standard shall be conducted at least quarterly. For systems using slow sand filtration or filtration treatment other than conventional filtration, direct filtration or diatomaceous earth filtration, the Department may reduce the sampling frequency to once per day.
C Shall continuously monitor the turbidity level of the combined filter effluent beginning August 20, , using an analytical method specified in 40 CFR For systems that do not operate continuously, the turbidity level shall also be measured and recorded at start-up and immediately prior to shutting down the plant. D Shall continuously monitor and record the residual disinfectant concentration of the water being supplied to the distribution system and record both the lowest value for each day and the number of periods each day when the value is less than 0.
Grab sampling or manual recording may not be substituted for continuous monitoring or recording for longer than 5 working days after the equipment fails. E Until April 28, , shall measure and record the residual disinfectant concentration at representative points in the distribution system no less frequently than the frequency required for total coliform sampling for compliance with the MCL for microbiological contaminants.
Measurements taken under this subclause may be used to meet the requirements under subclause II. II A public water supplier shall monitor the residual disinfectant concentration at representative locations in the distribution system at least once per week. Beginning January 1, , public water suppliers providing conventional or direct filtration and serving fewer than 10, people and using surface water or GUDI sources shall conduct continuous monitoring of turbidity for each individual filter using an approved method under the EPA regulation in 40 CFR Beginning August 20, , a public water supplier using surface water or GUDI sources and providing filtration treatment other than conventional or direct filtration shall conduct continuous monitoring of turbidity for each individual filter using an approved method under 40 CFR The public water supplier shall notify the Department within 24 hours of the equipment failure.
Grab sampling or manual recording may not be substituted for continuous monitoring for longer than 5 working days after the equipment fails. The Department will consider case-by-case extensions of the time frame to comply if the water supplier provides written documentation that it was unable to repair or replace the malfunctioning equipment within 5 working days due to circumstances beyond its control.
Regardless of source water turbidity, the minimum frequency of sampling for total coliform or E. II For systems that do not operate continuously, at start-up, at least once every 4 hours that the system is in operation, and also prior to shutting down the plant, except as provided in clause C. C May substitute continuous turbidity monitoring for grab sample monitoring until August 19, , if it validates the continuous measurement for accuracy on a regular basis using a procedure specified by the manufacturer.
D Shall continuously monitor and record the turbidity of the source water immediately prior to disinfection beginning August 20, , using an analytical method specified in 40 CFR If there is a failure in the continuous turbidity monitoring or recording equipment, or both, the supplier shall conduct grab sampling or manual recording, or both, every 4 hours in lieu of continuous monitoring or recording.
Grab sampling or manual recording may not be substituted for continuous monitoring for longer than 5 days after the equipment fails. F Until April 28, , shall measure the residual disinfectant concentration at representative points in the distribution system no less frequently than the frequency required for total coliform sampling for compliance with the MCL for microbiological contaminants.
A The water supplier shall calibrate turbidimeters using the procedure specified by the manufacturer. B If there is failure in the continuous turbidity monitoring or recording equipment, or both, the system shall conduct grab sampling or manual recording, or both, every 4 hours in lieu of continuous monitoring or recording.
C A public water supplier serving 10, or more persons has a maximum of 5 working days following the failure of the equipment to repair or replace the equipment before a violation is incurred. D A public water supplier serving fewer than 10, persons has a maximum of 14 days following the failure of the equipment to repair or replace the equipment before a violation is incurred.
C May substitute continuous turbidity monitoring for grab sample monitoring if it validates the continuous measurement for accuracy on a regular basis using a procedure specified by the manufacturer.
E Until April 28, , shall measure the residual disinfectant concentration at representative points in the distribution system no less frequently than the frequency required for total coliform sampling for compliance with the MCL for microbiological contaminants.
Public water systems shall determine the presence or absence of total coliforms for each routine or check sample; and, the presence or absence of E. A system may forego E. A system which chooses to forego E.
Systems which use groundwater and serve 4, persons or fewer may collect all required samples on a single day if they are from different sampling sites in the distribution system. A The number of monthly total coliform samples that a public water system shall take is based on the population served by the system as follows: Population Served Minimum Number of. B A public water system that uses either a surface water or a GUDI source and does not practice filtration in compliance with Subchapter B relating to MCLs, MRDLs or treatment technique requirements shall collect at least one total coliform sample at the entry point, or an equivalent location as determined by the Department, within 24 hours of each day that the turbidity level in the source water, measured as specified in paragraph 2 i B , exceeds 1.
These sample results shall be included in determining compliance with the MCL for E. These samples are considered special purpose samples under subparagraph v. E A community water system serving 1, people or fewer or a noncommunity water system may be required to begin monitoring on an alternate schedule established by the Department.
This determination will be made based on the results of a special monitoring evaluation performed during a sanitary survey. The system shall continue monitoring on the alternate schedule until otherwise notified by the Department. A public water system shall collect a set of check samples within 24 hours of being notified of a total coliform-positive routine sample, a total coliform-positive check sample or a total coliform-positive sample collected under subparagraph i B.
A A public water system shall collect at least three check samples for each routine total coliform-positive sample found. B The system shall collect at least one check sample from the sampling tap where the original total coliform-positive sample was taken. If a total coliform-positive sample occurs at the end of the distribution system or one service connection away from the end of the distribution system, the water supplier shall collect an additional check sample upstream of the original sample site in lieu of a downstream check sample.
C A system shall collect all check samples on the same day, except that a system with a single service connection may collect the required set of check samples all on the same day or consecutively over a 3-day period.
D At a minimum, the system shall collect one set of check samples for each total coliform-positive routine sample.
If a check sample is total coliform-positive, the public water system shall collect an additional set of check samples from the same locations in the manner specified in this subparagraph. E Results of all routine and check samples not invalidated by the Department shall be included in determining compliance with the MCL for E.
F If an upstream or downstream repeat monitoring location identified in the sample siting plan is not available in the time frame specified in this subparagraph, the public water system shall notify the Department prior to collecting the check sample that the check sample will be collected from a location within reasonable proximity to the routine monitoring location. A total coliform sample invalidated under this paragraph does not count towards meeting the minimum monitoring requirements of this section.
A The Department may invalidate a total coliform-positive sample if one of the following applies: I The laboratory which performed the analysis establishes that improper sample analysis caused the total coliform-positive result. II A domestic or other nondistribution system plumbing problem exists when a coliform contamination incident occurs that is limited to a specific service connection from which a coliform-positive sample was taken in a public water system with more than one service connection.
This type of sample invalidation does not apply to public water systems with only one service connection. III A total coliform-positive sample result is due to a circumstance or condition which does not reflect water quality in the distribution system.
In this case, the system shall still collect all check samples required under subparagraph ii to determine compliance with the MCL for E. The decision to invalidate a total coliform-positive sample result and supporting evidence will be documented by the Department, in writing, and approved and signed by the supervisor of the Department official who recommended the decision.
B A laboratory shall invalidate a total coliform sample if no total coliforms are detected and one of the following occurs: I The sample produces a turbid culture in the absence of gas production using an analytical method where gas formation is examined. II The sample exhibits confluent growth or produces colonies too numerous to count with an analytical method using a membrane filter. C If a laboratory invalidates a sample because of interference as specified in clause B , the laboratory shall notify the system within 1 business day to collect another sample from the same location as the original sample within 24 hours of being notified of the interference and have it analyzed for the presence of total coliforms.
The system shall resample within 24 hours of being notified of interference and continue to resample every 24 hours until it receives a valid result.
II The system has a total coliform-positive check sample following an E. III The system fails to take all required check samples following an E. IV The system fails to test for E. Special purpose samples, such as those taken to determine whether disinfection practices are sufficient following pipe placement, replacement or repair, those taken to investigate potential problems in the distribution system or those collected as part of a seasonal system start-up procedure, may not be used to determine compliance with the MCL for E.
Check samples taken under subparagraph ii are not considered special purpose samples, and shall be used to determine compliance with the monitoring, MCL and treatment technique requirements for total coliforms and E.
For a water system which complies with the performance monitoring requirements under paragraph 2 , the monitoring requirements for compliance with the turbidity MCL do not apply. Initial or first year monitoring mentioned in this paragraph refers to VOC monitoring conducted on or after January 1, Monitoring for compliance with the MCL for vinyl chloride is required for groundwater entry points at which one or more of the following two-carbon organic compounds have been detected: trichloroethylene, tetrachloroethylene, 1,2-dichloroethane, 1,1,1-trichloro-ethane, cis-1,2-dichloroethylene, trans-1,2-dichloro-ethylene or 1,1-dichloroethylene and shall consist of quarterly samples.
If the results of the first analysis do not detect vinyl chloride, monitoring shall be reduced to one sample during each compliance period. Surface water entry points shall monitor for vinyl chloride as specified by the Department. Initial monitoring shall consist of 4 consecutive quarterly samples at each entry point in accordance with the following monitoring schedule during the compliance period beginning January 1, , except for systems which are granted reduced initial monitoring in accordance with clauses E and F.
A system which monitors during the initial monitoring period, but begins monitoring before its scheduled initial monitoring year specified in this subparagraph, shall begin monitoring every entry point during the first calendar quarter of the year it begins monitoring, except as provided in clause E. A Systems serving more than 10, persons shall begin monitoring during the quarter beginning January 1, B Systems serving 3, persons to 10, persons shall begin monitoring during the quarter beginning January 1, C Systems serving to 3, persons shall begin monitoring during the quarter beginning January 1, D Systems serving fewer than persons shall begin monitoring during the quarter beginning January 1, E For systems serving 3, or fewer people which monitor at least one quarter prior to October 1, , and do not detect VOCs at an entry point during the first quarterly sample, the required initial monitoring is reduced to one sample at that entry point.
For systems serving to 3, people to qualify for this reduced monitoring, the initial monitoring shall have been conducted during the quarter beginning January 1, G Systems with new entry points associated with new sources which are permitted under Subchapter E relating to permit requirements to begin operation after December 31, , shall conduct initial monitoring as follows.
New entry points shall be monitored quarterly, beginning the first full quarter the entry point begins serving the public. For entry points at which a VOC is detected at a level equal to or greater than 0. B The Department may decrease the quarterly monitoring requirement specified in clause A provided it has determined that the system is reliably and consistently below the MCL.
For an initial detection of a VOC, the Department will not make this determination until the water system obtains results from a minimum of four consecutive quarterly samples that are reliably and consistently below the MCL. C If the Department determines that the system is reliably and consistently below the MCL, the Department may allow the system to monitor annually. Systems which monitor annually shall monitor during the quarter that previously yielded the highest analytical result, or as specified by the Department.
A For entry points at which VOCs are not detected during the first year of quarterly monitoring, or annual monitoring if only one sample was required at an entry point for first year monitoring under subparagraph ii E , or F , required monitoring is reduced to one sample per entry point per year. B For groundwater or GUDI entry points where VOCs are monitored in accordance with this paragraph, but are not detected during 3 years of quarterly or annual monitoring, or both, required monitoring is reduced to one sample per entry point during each subsequent compliance period.
Reduced monitoring shall be conducted at 3-year intervals from the year of required initial monitoring. For entry points at which a VOC MCL is exceeded, monitoring shall be conducted quarterly, beginning the quarter following the exceedance.
Quarterly monitoring shall continue until a minimum of 4 consecutive quarterly samples shows the system is in compliance as specified in subparagraph x and the Department determines the system is reliably and consistently below the MCL. If the Department determines that the system is in compliance and is reliably and consistently below the MCL, the Department may allow the system to monitor in accordance with subparagraph iii C.
The confirmation sample shall be collected within 2 weeks of notification by the accredited laboratory performing the analysis that an MCL has been exceeded. The average of the results of the original and the confirmation sample will be used to determine compliance. Monitoring shall be completed by the deadline specified for VOC compliance monitoring. When reduced monitoring is provided under subparagraph iii or iv , the system shall monitor the entry point during the calendar year quarter that previously yielded the highest analytical result, or as specified by the Department.
The reduced monitoring option in subparagraph iv B does not apply to entry points at which treatment has been installed for VOC removal. Quarterly performance monitoring is required for VOCs for which treatment has been installed. Waivers under 40 CFR Systems with groundwater or GUDI entry points which have 3 consecutive years of quarterly or annual samples with no detection of a VOC may apply to the Department for a waiver.
Entry points at which treatment has been installed to remove a VOC are not eligible for a monitoring waiver. A A use waiver may be granted to a public water supplier from conducting monitoring under subparagraph iii C , based on documentation provided by the public water supplier and a determination by the Department that the criteria has been met.
II If a determination by the Department reveals no previous use, a waiver may be granted. B If a use waiver is granted by the Department, required monitoring is reduced to one sample per entry point during each subsequent compliance period. Monitoring shall be conducted at 3-year intervals from the year of required initial monitoring.
C A use waiver is effective for one compliance period and may be renewed in each subsequent compliance period. D Susceptibility waivers under 40 CFR E Waiver requests and renewals shall be submitted to the Department, on forms provided by the Department, for review and approval prior to the end of the applicable monitoring period.
Until the waiver request or renewal is approved, the public water system is responsible for conducting all required monitoring. A The Department may invalidate results of obvious sampling errors. B A VOC sample invalidated under this subparagraph does not count towards meeting the minimum monitoring requirements of this paragraph.
A For systems monitoring more than once per year, compliance with the MCL is determined by a running annual average of all samples taken at each entry point. B If monitoring is conducted annually or less frequently, the system is out of compliance if the level of a contaminant at any entry point is greater than the MCL.
If a confirmation sample is collected as specified in subparagraph vi , compliance is determined using the average of the two sample results. C If any sample result will cause the running annual average to exceed the MCL at any entry point, the system is out of compliance with the MCL immediately.
D If a system fails to collect the required number of samples, compliance with the MCL will be based on the total number of samples collected. E If a sample result is less than the detection limit, zero will be used to calculate compliance. Initial monitoring shall consist of 4 consecutive quarterly samples at each entry point beginning during the quarter beginning January 1, , except for systems which are granted an initial monitoring waiver in accordance with subparagraph vii.
Systems which monitor during the initial monitoring period but begin monitoring before shall begin monitoring during the first calendar quarter of the year. New entry points associated with new sources which are vulnerable to SOC contamination, as determined in accordance with subparagraph vii , and which begin operation after March 31, , shall be monitored quarterly, beginning the first full quarter the entry point begins serving the public.
For an initial detection of a SOC, the Department will not make this determination until the water system obtains results from a minimum of four consecutive quarterly samples that are reliably and consistently below the MCL. D Systems which have 3 consecutive years of quarterly or annual samples with no detection of a contaminant may apply to the Department for a waiver as specified in subparagraph vii.
A waiver is effective for one compliance period and may be renewed in each subsequent compliance period. E For entry points at which either heptachlor or heptachlor epoxide is detected during the initial round of consecutive quarterly samples, or in subsequent repeat samples, the monitoring shall be continued for both contaminants in accordance with the more frequent monitoring required of the two contaminants based on the level at which each is detected.
For entry points at which SOCs are not detected during the first year of quarterly monitoring, the required monitoring is reduced to one sample in each 3-year compliance period for systems serving 3, or fewer persons and to 2 consecutive quarterly samples in each compliance period for systems serving more than 3, persons. Reduced monitoring shall be conducted at 3-year intervals from the year of required initial VOC monitoring, in accordance with paragraph 5 ii.
Quarterly monitoring shall continue until a minimum of 4 consecutive quarterly samples shows the system is in compliance as specified in subparagraph ix and the Department determines the system is reliably and consistently below the MCL. If the Department determines that the system is in compliance and is reliably and consistently below the MCL, the Department may allow the system to monitor in accordance with subparagraph ii C.
The confirmation sample shall be collected within 2 weeks of the water supplier receiving notification from the accredited laboratory performing the analysis that an MCL has been exceeded. The average of the results of the original and the confirmation samples will be used to determine compliance. Confirmation monitoring shall be completed by the deadline specified for SOC compliance monitoring. When reduced monitoring is provided under subparagraph ii or iii , the system shall monitor the entry point during the second calendar year quarter, or the second and third calendar year quarter when 2 quarterly samples are required in each compliance period, unless otherwise specified by the Department.
The reduced monitoring option in subparagraph iii does not apply to entry points at which treatment has been installed for SOC removal. Compliance monitoring for SOCs for which treatment has been installed to comply with an MCL shall be conducted at least annually, and performance monitoring shall be conducted quarterly. A waiver will be granted to a public water supplier from conducting the initial compliance monitoring or repeat monitoring, or both, for an SOC based on documentation provided by the public water supplier and a determination by the Department that the criteria in clause B , C or D has been met.
If the Department has not granted a use waiver in accordance with clause B , the public water supplier is responsible for submitting a waiver application and renewal application to the Department for review in accordance with clause B , C or D for specific entry points. Waiver applications will be evaluated relative to the vulnerability assessment area described in clause A and the criteria in clause B , C or D.
Entry points at which treatment has been installed to remove an SOC are not eligible for a monitoring waiver for the SOCs for which treatment has been installed. II For surface water entry points, the vulnerability assessment area shall consist of the area that supplies water to the entry point and is separated from other watersheds by the highest topographic contour.
B Use waivers. A use waiver will be granted by the Department for contaminants which the Department has determined have not been used, stored, manufactured, transported or disposed of in this Commonwealth, or portions of this Commonwealth. A use waiver specific to a particular entry point requires that an SOC was not used, stored, manufactured, transported or disposed of in the vulnerability assessment area.
If use waiver criteria cannot be met, a public water supplier may apply for a susceptibility waiver. C Susceptibility waivers. A susceptibility waiver for specific contaminants may be granted based on the following criteria, and only applies to groundwater entry points: I Previous analytical results. II Environmental persistence and transport of the contaminant.
III Proximity of the drinking water source to point or nonpoint source contamination. IV Elevated nitrate levels as an indicator of the potential for pesticide contamination. V Extent of source water protection or approved wellhead protection program. D Waiver requests and renewals.
Waiver requests and renewals shall be submitted to the Department, on forms provided by the Department, for review and approval prior to the end of the applicable monitoring period. B An SOC sample invalidated under this subparagraph does not count towards meeting the minimum monitoring requirements of this paragraph. If a confirmation sample is collected as specified in subparagraph v , compliance is determined using the average of the two sample results.
Transient noncommunity water suppliers shall monitor for compliance with the MCLs for nitrate and nitrite. The requirements are incorporated by reference except as modified by this chapter.
A Monitoring frequency. Community water systems and nontransient noncommunity water systems not granted a waiver under clause F shall monitor for compliance with the MCL for asbestos by taking one sample at each vulnerable sampling point during the first 3-year compliance period of each 9-year compliance cycle, with the initial compliance monitoring beginning not later than the calendar year beginning January 1, B Sampling points.
A system shall monitor at the following locations: I Each entry point to the distribution system. II At least one representative location within the distribution system identified in a written sample site plan that includes a materials evaluation of the distribution system.
The written sample site plan shall be maintained on record and submitted to the Department prior to conducting initial monitoring or upon request.
C Monitoring of new entry points. New entry points which begin operation after December 31, , shall conduct initial monitoring during the first compliance period of the first compliance cycle after the entry point begins serving the public, if the Department determines that a waiver cannot be granted in accordance with clause F.
D Repeat monitoring for systems that exceed the asbestos MCL. If a sample exceeds the MCL for asbestos, the monitoring at that sampling point shall be continued quarterly beginning in the quarter following the MCL exceedance. After four consecutive quarterly samples with results reliably and consistently below the MCL at that entry point, the required monitoring is reduced to one sample at that entry point during the first 3-year compliance period of each subsequent 9-year compliance cycle, if treatment has not been installed to remove asbestos from the source water.
Compliance monitoring at entry points at which treatment has been installed to remove asbestos from source water shall be conducted at least annually, and performance monitoring shall be conducted quarterly. E Confirmation samples. For asbestos sample results in excess of the MCL during annual or less frequent compliance monitoring, the water supplier shall take a confirmation sample within 2 weeks of notification by the accredited laboratory performing the analysis.
Monitoring shall be completed by the deadline specified for asbestos compliance monitoring. F Waivers for asbestos monitoring. A waiver will be granted to a public water supplier from conducting compliance monitoring for asbestos based on documentation provided by the public water supplier and a determination by the Department that the criteria in this clause have been met. Entry points at which treatment has been installed to remove asbestos are not eligible for a monitoring waiver.
I A waiver for entry point compliance monitoring may be granted if the sources supplying the entry point are not vulnerable to asbestos contamination. II A waiver for distribution system monitoring may be granted if the distribution system does not contain asbestos cement pipe as indicated in the materials evaluation or if the water system has optimized corrosion control as specified in Subchapter K relating to lead and copper.
III Waiver requests and renewals shall be submitted to the Department, on forms provided by the Department, for review and approval prior to the end of the applicable monitoring period. A Initial monitoring schedule. A public water system shall begin monitoring for nitrate and nitrite by taking one annual sample at each groundwater or GUDI entry point to the distribution system beginning during the year beginning January 1, Community water systems and nontransient noncommunity water systems with surface water sources shall monitor quarterly at each surface water entry point for nitrate and nitrite beginning during the quarter beginning January 1, Transient noncommunity water systems shall monitor each surface water entry point by taking one annual sample beginning during the year beginning January 1, B Monitoring of new entry points.
I New community and nontransient noncommunity surface water entry points associated with new sources shall be monitored quarterly, beginning the first full quarter the entry point begins serving the public.
Quarterly monitoring shall continue until reduced monitoring is granted in accordance with clause C II or D. II New community and nontransient noncommunity groundwater or GUDI entry points and new transient noncommunity entry points associated with new sources shall be monitored annually, beginning within 1 year of serving the public. Annual monitoring shall be conducted during the quarter which previously resulted in the highest analytical result, unless the Department determines that a different monitoring quarter should be used in accordance with paragraph III For groundwater or GUDI entry points, after 4 consecutive quarterly samples at an entry point for a water system indicate nitrate and nitrite levels in each sample are reliably and consistently below the MCL, the required compliance monitoring is reduced to 1 sample per year at the entry point.
IV For nitrate or nitrite sample results in excess of the MCLs, the water supplier shall take a confirmation sample within 24 hours of having received the original sample result. Systems exercising this option shall take and analyze a confirmation sample within 2 weeks of notification of the analytical results of the first sample. V Noncommunity water systems for which an alternate nitrate level has been approved by the Department in accordance with 40 CFR Confirmation monitoring shall be completed by the deadline for compliance monitoring.
VI Quarterly performance monitoring is required for nitrate and nitrite at entry points where treatment has been installed to remove nitrate or nitrite. Community water systems and nontransient noncommunity water systems shall monitor each surface water entry point annually beginning during the year beginning January 1, , and shall monitor each groundwater or GUDI entry point once every 3 years beginning during the year beginning January 1, New surface water entry points shall begin initial annual monitoring during the first new calendar year after the entry point begins serving the public.
I For entry points at which initial monitoring results or subsequent monitoring indicates an IOC level in excess of the MCL, monitoring shall be repeated quarterly beginning the quarter following detection at that level for each IOC in excess of an MCL, until reduced monitoring is granted in accordance with subclause II. II After analyses of four consecutive quarterly samples indicate that contaminant levels are reliably and consistently below the MCLs, the required monitoring at an entry point where treatment has not been installed to comply with an IOC MCL for each IOC that is reliably and consistently below the MCL is reduced to the frequencies stated in clause A.
This reduced monitoring option does not apply to entry points at which treatment has been installed for IOC removal. Compliance monitoring for IOCs for which treatment has been installed to comply with an MCL shall be conducted at least annually, and performance monitoring shall be conducted quarterly. Confirmation monitoring shall be completed by the deadline specified for IOC compliance monitoring. D Waivers for antimony, arsenic, barium, beryllium, cadmium, chromium, fluoride, mercury, nickel, selenium and thallium monitoring.
Except when treatment has been installed to remove the IOC, after 3 consecutive rounds of quarterly, annual or triennial monitoring indicate the contaminant level for an IOC is reliably and consistently below the MCL in all samples at an entry point, routine monitoring for the remainder of the compliance cycle for that IOC may be waived and the required monitoring for the IOC may be reduced to 1 sample per 9-year compliance cycle at that entry point.
I Waivers may be granted based on the following criteria: -a- Previous analytical results. II A decision by the Department to grant a waiver will be made in writing and will set forth the basis for the determination.
The determination may be made upon an application by the public water system. The public water system shall specify the basis for its request. III Reduced monitoring shall be conducted during the first monitoring period of the next monitoring cycle. A waiver is effective for one compliance cycle and may be renewed in each subsequent compliance cycle. IV Waiver requests and renewals shall be submitted to the Department, on forms provided by the Department, for review and approval prior to the end of the applicable monitoring period.
E Waivers for cyanide monitoring. Waivers may be granted for monitoring of cyanide, provided that the system is not vulnerable due to lack of any industrial source of cyanide.
F Operational monitoring for fluoride. Public water suppliers who fluoridate shall conduct operational monitoring for fluoride daily. B An IOC sample invalidated under this subparagraph does not count towards meeting the minimum monitoring requirements of this section.
A For systems monitoring more than once per year, compliance with the MCL for antimony, arsenic, asbestos, barium, beryllium, cadmium, chromium, cyanide, fluoride, mercury, nickel, selenium or thallium is determined by a running annual average of all samples taken at each entry point. If the average at any entry point is greater than the MCL, then the system is out of compliance.
If any one sample would cause the annual average to be exceeded, then the system is out of compliance immediately. B For systems monitoring annually, or less frequently, the system is out of compliance with the MCL for antimony, arsenic, asbestos, barium, beryllium, cadmium, chromium, cyanide, fluoride, mercury, nickel, selenium or thallium if the level of a contaminant at any sampling point is greater than the MCL.
If a confirmation sample is collected as specified in subparagraph ii C III , compliance is determined using the average of the two samples. 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, a confirmation sample is required in accordance with subparagraph ii C III , and compliance shall be determined based on the average of the initial and confirmation samples.
As a minimum, the monitoring shall include the MCLs for which the POE device is intended to treat and monthly microbiological monitoring. The Department may allow the water supplier to reduce the frequency of microbiological monitoring based upon historical performance. The Department may by written notice require a public water supplier to conduct monitoring for compliance with MCLs or MRDLs during a specific portion of a monitoring period, if necessary to ensure compliance with the monitoring or reporting requirements in this chapter.
Community water systems and nontransient noncommunity water systems that use a chemical disinfectant or oxidant shall monitor for disinfection byproducts and disinfection byproduct precursors in accordance with this paragraph.
Community water systems and nontransient noncommunity water systems that obtain finished water from another public water system that uses a chemical disinfectant or oxidant to treat the finished water shall monitor for TTHM and HAA5 in accordance with this paragraph.
