NR 809.55(2)(2) Source water monitoring reporting requirements. NR 809.55(2)(a)(a) A water supplier shall report the sampling results for all source water samples collected in accordance with s. NR 809.549 within the first 10 days following the end of each source water monitoring period, i.e., annually, per compliance period, per compliance cycle specified in s. NR 809.549. NR 809.55(2)(b)(b) With the exception of the first round of source water sampling conducted pursuant to s. NR 809.549 (2), the water supplier shall specify any site which was not sampled during previous monitoring periods, and include an explanation of why the sampling point has changed. NR 809.55(3)(3) Corrosion control treatment reporting requirements. By the applicable dates under s. NR 809.542, the water supplier shall report the following information: NR 809.55(3)(a)(a) For water supplier of public water systems demonstrating that they have already optimized corrosion control, information required in s. NR 809.542 (2) (b) or (c). NR 809.55(3)(b)(b) For water supplier of public water systems required to optimize corrosion control, their recommendation regarding optimal corrosion control treatment under s. NR 809.543 (1). NR 809.55(3)(c)(c) For water supplier of public water systems required to evaluate the effectiveness of corrosion control treatments under s. NR 809.543 (3), the information required by that section. NR 809.55(3)(d)(d) For water supplier of public water systems required to install optimal corrosion control approved by the department under s. NR 809.543 (4), a letter certifying that the water supplier has completed installing that treatment. NR 809.55(4)(4) Source water treatment reporting requirements. By the applicable dates in s. NR 809.544, water supplier shall provide the following information to the department: NR 809.55(4)(b)(b) For water suppliers required to install source water treatment under s.

NR 809.55(5)(5) Lead service line replacement reporting requirements. Water suppliers shall report the following information to the department to demonstrate compliance with the requirements of s. NR 809.545: NR 809.55(5)(a)(a) No later than 12 months after the end of a monitoring period in which a public water system exceeds the lead action level in sampling referred to in s. NR 809.545 (1), the water supplier must submit written documentation to the department of the material evaluation conducted as required in s. NR 809.547 (1), identify the initial number of lead service lines in the distribution system of the public water system at the time the public water system exceeded the lead action level, and provide the public water system’s schedule for annually replacing at least 7% of the initial number of lead service lines in its distribution system. NR 809.55(5)(b)(b) No later than 12 months after the end of a monitoring period in which a public water system exceeds the lead action level in sampling referred to in s. NR 809.545 (1), and every 12 months thereafter, the water supplier shall demonstrate to the department in writing that the public water system has done one of the following: NR 809.55(5)(b)1.1.
