[30 Pa.B. 4596]

[Continued from previous Web Page]

   (-a-)  Systems serving at least 10,000 persons may reduce monitoring to one sample per quarter per treatment plant. The sample shall be taken at a location that represents a maximum residence time. Systems on reduced monitoring are not required to monitor source water TOC.

   (-b-)  Systems serving from 500 to 9,999 persons may reduce monitoring to one sample per year per treatment plant. The sample shall be taken during the month of warmest water temperature and at a location that represents a maximum residence time. Systems on reduced monitoring are not required to monitor source water TOC.

   (-c-)  Systems serving fewer than 500 persons and that are on increased monitoring as prescribed by clause (A) may reduce monitoring to one sample per year per treatment plant. The sample shall be taken during the month of warmest water temperature and at a location that represents a maximum residence time. Systems on reduced monitoring are not required to monitor source water TOC.

   (II)  Systems that use groundwater sources may reduce monitoring according to the following:

   (-a-)  Systems serving at least 10,000 persons may reduce monitoring to one sample per year per treatment plant if the annual TTHM average is no greater than 0.040 mg/L and the annual HAA5 average is no greater than 0.030 mg/L. The sample shall be taken during the month of warmest water temperature and at a location that represents a maximum residence time. Systems that qualify for reduced monitoring may remain on reduced monitoring provided that the annual TTHM average is no greater than 0.060 mg/L and the annual HAA5 average is no greater than 0.045 mg/L. Systems that exceed these levels shall resume routine monitoring as prescribed in clause (A) in the quarter immediately following the quarter in which the system exceeds 0.060 mg/L for TTHMs or 0.045 mg/L for HAA5.

   (-b-)  Systems serving fewer than 10,000 persons may reduce monitoring to one sample per 3-year cycle per treatment plant if the annual TTHM average is no greater than 0.040 mg/L and the annual HAA5 average is no greater than 0.030 mg/L for 2 consecutive years or the annual TTHM average is no greater than 0.020 mg/L and the annual HAA5 average is no greater than 0.015 mg/L for 1 year. The sample shall be taken during the month of warmest water temperature within the 3-year cycle beginning on January 1 following the quarter in which the system qualifies for reduced monitoring. The sample shall be taken at a location that represents a maximum residence time. Systems that qualify for reduced monitoring may remain on reduced monitoring provided that the annual TTHM average is no greater than 0.080 mg/L and the annual HAA5 average is no greater than 0.060 mg/L. Systems that exceed these levels shall resume routine monitoring as prescribed in clause (A) in the quarter immediately following the quarter in which the system exceeds 0.080 mg/L for TTHMs or 0.060 mg/L for HAA5.

   (ii)  Chlorite. Community water systems and nontransient noncommunity water systems that use chlorine dioxide for disinfection or oxidation, or provide finished water that contains chlorine dioxide, shall monitor for chlorite.

   (A)  Routine monitoring.

   (I)  Daily monitoring. Systems shall take daily samples at the entrance to the distribution system. Systems that must conduct additional monitoring in accordance with clause (B) shall continue to take routine daily samples at the entrance to the distribution system.

   (II)  Monthly monitoring. Systems shall take a three-sample set each month in the distribution system. The system shall take one sample at each of the following locations: as close to the first customer as possible; at a location representing an average residence time; and at a location representing a maximum residence time. Systems that must conduct additional monitoring in accordance with subclause (III) may use the results of the additional monitoring to meet the monthly monitoring requirements of this subclause.

   (III)  Additional monitoring. If a daily sample at the entrance to the distribution system exceeds the chlorite MCL, the system shall take three samples in the distribution system on the following day. The system shall take one sample at each of the following locations: as close to the first customer as possible, at a location representing an average residence time and at a location representing a maximum residence time.

   (B)  Reduced monitoring. Chlorite monitoring in the distribution system required by clause (A)(II) may be reduced to one three-sample set per quarter after 1 year of monitoring where no individual chlorite sample taken in the distribution system under clause (A)(II) has exceeded the chlorite MCL and the system has not been required to conduct additional monitoring under clause (A)(III). The system may remain on the reduced monitoring schedule until either any of the three individual chlorite samples taken quarterly in the distribution system exceeds the chlorite MCL or the system is required to conduct additional monitoring under clause (A)(III), at which time the system shall revert to routine monitoring as prescribed by clause (A).

   (iii)  Bromate. Community water systems and nontransient noncommunity water systems that use ozone for disinfection or oxidation, or provide finished water that contains ozone, shall monitor for bromate.

   (A)  Routine monitoring. Systems shall take one sample per month for each treatment plant that uses ozone. Systems shall take the monthly sample at the entrance to the distribution system while the ozonation system is operating under normal conditions.

   (B)  Reduced monitoring. Systems required to analyze for bromate may reduce monitoring from monthly to quarterly provided that the system demonstrates that the average source water bromide concentration is less than 0.05 mg/L based upon representative monthly bromide measurements for 1 year. Systems on reduced monitoring shall continue to take monthly samples for source water bromide. Systems may remain on reduced bromate monitoring until the running annual average source water bromide concentration, computed quarterly, is equal to or greater than 0.05 mg/L based upon representative monthly measurements, at which time the system shall revert to routine monitoring as prescribed by clause (A).

   (iv)  Disinfection byproduct precursors. Systems that use either surface water or GUDI sources and that use conventional filtration shall monitor for disinfection byproduct precursors.

   (A)  Routine monitoring. Systems shall take monthly samples of the source water alkalinity, the source water TOC and the combined filter effluent TOC for each treatment plant that uses conventional filtration. The three samples shall be taken concurrently and at a time that is representative of both normal operating conditions and influent water quality.

   (B)  Reduced monitoring. Systems with an average treated water TOC of less than 2.0 mg/L for 2 consecutive years, or less than 1.0 mg/L for 1 year, may reduce monitoring for source water alkalinity, source water TOC and combined filter effluent TOC from monthly to quarterly for each applicable treatment plant. The system shall revert to routine monitoring as prescribed by clause (A) in the month following the quarter when the annual average treated water TOC is not less than 2.0 mg/L.

   (C)  Early monitoring. Systems may begin monitoring to determine whether the TOC removal requirements of 40 CFR 141.135(b)(1) (relating to enhanced coagulation and enhanced softening performance requirements) can be met 12 months prior to the compliance date for the system. This monitoring is not required and failure to monitor during this period is not a violation. However, any system that does not monitor during this period, and then determines in the first 12 months after the compliance date that it is not able to meet the requirements of 40 CFR 141.135(b)(1) and must therefore apply for alternate minimum TOC removal requirements under 40 CFR 141.135(b)(4) is not eligible for retroactive approval of the alternate minimum TOC removal requirements and is in violation. Systems may apply for alternate minimum TOC removal requirements any time after the compliance date.

   (13)  Monitoring requirements for disinfectant residuals. Community water systems and nontransient noncommunity water systems that use a chemical disinfectant or oxidant, or provide finished water that contains a chemical disinfectant or oxidant, shall monitor for disinfectant residuals. Transient noncommunity water systems that use chlorine dioxide as either a disinfectant or oxidant shall monitor for chlorine dioxide disinfectant residual. Systems that use either surface water or GUDI sources and that serve at least 10,000 persons shall begin monitoring by January 1, 2002. Systems that use either surface water or GUDI sources and that serve fewer than 10,000 persons, or systems that use groundwater sources, shall begin monitoring by January 1, 2004. Systems monitoring for disinfectant residuals shall take all samples during normal operating conditions. Compliance with the MRDLs and monitoring requirements for chlorine, chloramines and chlorine dioxide (where applicable) shall be determined in accordance with 40 CFR 141.132 and 141.133 (relating to monitoring requirements; and compliance requirements) which are incorporated herein by reference.

   (i)  Chlorine and chloramines. Systems shall measure the residual disinfectant level at the same points in the distribution system and at the same time that total coliforms are samples, as specified in paragraph (3). Systems that used either surface water or GUDI sources may use the results of residual disinfectant concentration sampling conducted under paragraph (1) or (2) in lieu of taking separate samples.

   (ii)  Chlorine dioxide.

   (A)  Routine monitoring. Systems shall take one sample per day at the entrance to the distribution system. For any daily sample that exceeds the MRDL, the system shall conduct additional monitoring as specified in clause (B) in addition to the sample required at the entrance to the distribution system. Compliance shall be based on consecutive daily samples collected by the system under this clause.

   (B)  Additional monitoring. If a daily sample at the entrance to the distribution system exceeds the chlorine dioxide MRDL, the system shall take three samples in the distribution system on the following day. If chlorine dioxide or chloramines are used to maintain a disinfectant residual in the distribution system, or if chlorine is used to maintain a disinfectant residual in the distribution system and there are no disinfectant addition points after the entrance to the distribution system, the system shall take three samples as close to the first customer as possible, at intervals of at least 6 hours. If chlorine is used to maintain a disinfectant residual in the distribution system and there are one or more disinfection addition points after the entrance to the distribution system, the system shall take one sample at each of the following locations: as close to the first customer as possible, at a location representing an average residence time, and at a location representing a maximum residence time.
