(2) New enforcement actions taken by the State during the previous quarter against public water systems with respect to State regulations adopted to incorporate the requirements of national primary drinking water regulations;
(3) Notification of any new variance or exemption granted during the previous quarter. The notice shall include a statement of reasons for the granting of the variance or exemption, including documentation of the need for the variance or exemption and the finding that the granting of the variance or exemption will not result in an unreasonable risk to health. The State may use a single notification statement to report two or more similar variances or exemptions.
(b) Each State which has primary enforcement responsibility must submit annual reports to the Administrator on a schedule and in a format prescribed by the Administrator, consisting of the following information:
(1) All additions or corrections to the State's inventory of public water systems;
(2) A summary of the status of each variance and exemption currently in effect; and

(c) Special reports—(1) Surface Water Treatment Rule. (i)(A) A list identifying the name, PWS identification number and date of the determination for each public water system supplied by a surface water source or a ground water source under the direct influence of surface water, which the State has determined is not required to provide filtration treatment.
(B) A list identifying the name and PWS identification number of each public water system supplied by a surface water source or ground water source under the direct influence of surface water, which the State has determined, based on an evaluation of site-specific considerations, has no means of having a sample transported and analyzed for HPC by a certified laboratory under the requisite time and temperature conditions specified in § 141.74(a)(3) and is providing adequate disinfection in the distribution system, regardless of whether the system is in compliance with the criteria of § 141.72 (a)(4)(i) or (b)(3)(i) of this chapter, as allowed by § 141.72 (a)(4)(ii) and (b)(3)(ii). The list must include the effective date of each determination.

The notification must include a statement describing the system's compliance with each requirement of the State's regulations that implement § 141.71 and a summary of comments, if any, received from the public on the determination. A single notification may be used to report two or more such determinations.
(2) Total coliforms. A list of public water systems which the State is allowing to monitor less frequently than once per month for community water systems or less frequently than once per quarter for non-community water systems as provided in § 141.21(a), including the effective date of the reduced monitoring requirement for each system.
(3) Total coliforms under subpart Y. A list of systems that the State is allowing to monitor less frequently than once per month for community water systems or less frequently than once per quarter for non-community water systems as provided in §§ 141.855 and 141.854 of this chapter, including the applicable date of the reduced monitoring requirement for each system.
(4) Timing. States shall report quarterly, in a format and on a schedule prescribed by the Administrator, the following information related to each system's compliance with the treatment techniques for lead and copper under 40 CFR part 141, subpart I, during the preceding calendar quarter. Specifically, States shall report as follows:
(i) States shall report the name and PWS identification number:
(A) Each public water system which exceeded the lead and copper action levels and the date upon which the exceedance occurred;
(B) Each public water system required to complete the corrosion control evaluation specified in § 141.82(c) and the date the State received the results of the evaluations from each system;
(C) Each public water system for which the State has designated optimal corrosion control treatment under § 141.82(d), the date of the determination, and each system that completed installation of treatment as certified under § 141.90(c)(3);
(D) Each public water system for which the State has designated optimal water quality parameters under § 141.82(f) and the date of the determination;
(E) Each public water system which the State has required to install source water treatment under § 141.83(b)(2), the date of the determination, and each system that completed installation of treatment as certified under § 141.90(d)(2);
(F) Each public water system for which the State has specified maximum permissible source water levels under § 141.83(b)(4); and
(G) Each public water system required to begin replacing lead service lines as specified in § 141.84, each public water system for which the State has established a replacement schedule under § 141.84(f), and each system reporting compliance with its replacement schedule under § 141.90(e)(2).
(ii) [Reserved]
(iii) States shall report the PWS identification number of each public water system identified in paragraphs (c)(4)(iii)(A) through (F) of this section.
(A) For each public water system, regardless of size, all 90th percentile lead levels calculated during each tap sampling period specified in § 141.86 of this chapter, and the first and last days of the tap sampling period for which the 90th percentile lead level was calculated;
