NR 809.546(2)(e)(e) Requirements for continuing non-transient non-community water system exceedances. A water supplier for a non-transient non-community water system shall repeat the tasks contained in par. (d) at least once during each calendar year in which the public water system exceeds the lead action level. The department may, on a case-by-case basis, allow activities in par. (d) to extend beyond the 60-day requirement if needed for implementation purposes. However, this extension is required to be approved in writing by the department in advance of the 60-day deadline.

NR 809.546(2)(f)(f) Requirements for discontinuing public education materials.

NR 809.547. The water supplier shall recommence public education in accordance with this section if the public water system subsequently exceeds the lead action level during any monitoring period.

NR 809.546(2)(g)(g) Community water system text waiver. A water supplier for a community water system may apply to the department in writing unless the department has waived the requirement for prior approval, to use only the text specified in sub. (1) (a) in lieu of the text in sub. (1) (a) and (b) and to perform the tasks listed in pars. (d) and (e) in lieu of the tasks in pars. (b) and (c) if all of the following are met:

NR 809.546(2)(h)3.3. With respect to the requirements of par. (b) 5., the department may waive this requirement for public water systems serving 3,300 or fewer persons as long as the water supplier distributes notices to every household served by the public water system.

NR 809.547 shall offer to sample the tap water of any customer who requests it. The water supplier is not required to pay for collecting or analyzing the sample, nor is the water supplier required to collect and analyze the sample.

NR 809.546(4)(a)(a) Reporting requirement. All water suppliers for public water systems shall provide a notice of the individual tap results from lead tap water monitoring carried out under the requirements of s. NR 809.547 to the persons served by the public water system at the specific sampling site from which the sample was taken, for example, the occupants of the residence where the tap was tested.

NR 809.546(4)(b)(b) Timing of notification. A water supplier shall provide the consumer notice as soon as practical, but no later than 30 days after the water supplier learns of the tap monitoring results.

NR 809.546(4)(c)(c) Content. The consumer notice shall include the results of lead tap water monitoring for the tap that was tested, an explanation of the health effects of lead, steps consumers can take to reduce exposure to lead in drinking water and contact information for the water utility. The notice shall also provide the maximum contaminant level goal and the action level for lead and the definitions for these two terms from s. NR 809.833 (2).

NR 809.546(4)(d)(d) Delivery. The consumer notice shall be provided to persons served at the tap that was tested, either by mail or by another method approved by the department. For example, upon approval by the department, a non-transient noncommunity water system could post the results on a bulletin board in the facility to allow users to review the information. The water supplier shall provide the notice to customers at sample taps tested, including consumers who do not receive water bills.
