NR 809.544(1)(f)(f) Step 6: The water supplier shall operate in compliance with the department-specified maximum permissible lead and copper source water levels and continue source water monitoring. NR 809.544(2)(2) Description of source water treatment requirements. NR 809.544(2)(a)(a) Water supplier treatment recommendation. Any water supplier for a public water system that exceeds the lead or copper action level shall recommend in writing to the department the installation and operation of one of the source water treatments listed in par. (b). A water supplier may recommend that no treatment be installed based upon a demonstration that source water treatment is not necessary to minimize lead and copper levels at users’ taps. NR 809.544(2)(b)(b) Department determination regarding source water treatment. The water supplier shall complete an evaluation of the results of all source water samples collected by the water supplier to determine whether source water treatment is necessary to minimize lead or copper levels and the evaluation shall be submitted to the department. If the department determines that treatment is needed, the department shall either approve installation and operation of the source water treatment recommended by the water supplier, if any, or require the installation and operation of another source water treatment from among the following: ion exchange, reverse osmosis, lime softening or coagulation-filtration. If the department requests additional information to aid in its review, the water supplier shall provide the information by the date specified by the department in its request. The department shall notify the water supplier in writing of its determination and set forth the basis for its decision. NR 809.544(2)(c)(c) Installation of source water treatment. Each water supplier shall properly install and operate the source water treatment approved by the department under par. (b). NR 809.544(2)(d)(d) Department review of source water treatment and specification of maximum permissible source water levels. The department shall review the source water samples taken by the water supplier both before and after the water supplier installs source water treatment, and determine whether the water supplier has properly installed and operated the source water treatment approved by the department. Based upon its review, the department shall establish the maximum permissible lead and copper concentrations for finished water entering the distribution system. Levels shall reflect the contaminant removal capability of the treatment properly operated and maintained. The department shall notify the water supplier in writing and explain the basis for its decision. NR 809.544(2)(e)(e) Continued operation and maintenance. Each water supplier shall maintain lead and copper levels below the maximum permissible concentrations established by the department at each sampling point monitored in accordance with s. NR 809.549. The public water system is out of compliance with this paragraph if the level of lead or copper at any sampling point is greater than the maximum permissible concentration approved by the department. NR 809.544(2)(f)(f) Modification of department treatment decisions. Upon its own initiative or in response to a request by a water supplier or other interested party, the department may modify its determination of the source water treatment under par. (b), or maximum permissible lead and copper concentrations for finished water entering the distribution system under par. (d). A request for modification by a water supplier or other interested party shall be in writing, explain why the modification is appropriate, and provide supporting documentation. The department may modify its determination where it concludes that such change is necessary to ensure that the water supplier continues to minimize lead and copper concentrations in source water. A revised determination shall be made in writing, set forth the new treatment requirements, explain the basis for the department’s decision, and provide an implementation schedule for completing the treatment modifications. NR 809.544(2)(g)(g) Treatment decisions by EPA in lieu of the department. The EPA regional administrator may review treatment determinations made by the department under par. (b), (d) or (f) and issue federal treatment determinations consistent with the requirements of those paragraphs if the administrator finds any of the following: NR 809.544(2)(g)1.1. The department has failed to issue a treatment determination by the applicable deadlines contained in sub. (1). NR 809.544(2)(g)2.2. The department has abused its discretion in a substantial number of cases or in cases affecting a substantial population. NR 809.544(2)(g)3.3. The technical aspects of the department’s determination would be indefensible in an expected federal enforcement action taken against a water supplier. NR 809.544 HistoryHistory: CR 09-073: cr. Register November 2010 No. 659, eff. 12-1-10; CR 15-049: am. (1) (a) Register March 2016 No. 723, eff. 4-1-16. NR 809.545NR 809.545 Lead service line replacement requirements. NR 809.545(1)(1) General. Water suppliers for public water systems that fail to meet the lead action level in tap samples taken pursuant to s. NR 809.547 (4) (b), after installing corrosion control or source water treatment, or both, whichever sampling occurs later, shall replace lead service lines in accordance with the requirements of this section. If a public water system is in violation of s. NR 809.542 or 809.544 for failure to install source water or corrosion control treatment, the department may require the water supplier to commence lead service line replacement under this section after the date by which the water supplier was required to conduct monitoring under s. NR 809.547 (4) (b) has passed. NR 809.545(2)(a)(a) A water supplier shall replace annually at least 7% of the initial number of lead service lines in its distribution system. The initial number of lead service lines is the number of lead lines in place at the time the replacement program begins. The water supplier shall identify the initial number of lead service lines in its distribution system, including an identification of the portions owned by the public water system, based on a materials evaluation, including the evaluation required under s. NR 809.547 (1) and relevant legal authorities, such as contracts and local ordinances regarding the portion owned by the public water system. The first year of lead service line replacement shall begin on the first day following the end of the monitoring period in which the action level was exceeded under sub. (1). If monitoring is required annually or less frequently, the end of the monitoring period is September 30 of the calendar year in which the sampling occurs unless the department has established an alternate monitoring period. NR 809.545(2)(b)(b) Any water supplier resuming a lead service line replacement program, after the cessation of its lead service line replacement program, as allowed by sub. (6), shall update the public water system’s inventory of lead service lines to include those sites that were previously determined not to require replacement through the sampling provision under sub. (3). The water supplier shall then divide the updated number of remaining lead service lines by the number of remaining years in the program to determine the number of lines that must be replaced per year. Seven percent lead service line replacement is based on a 15-year replacement program, so, for example, water suppliers resuming lead service line replacement after previously conducting two years of replacement would divide the updated inventory by 13. For those water suppliers for public water systems that have completed a 15-year lead service line replacement program, the department will determine a schedule for replacing or retesting lines that were previously tested out under the replacement program when the public water system exceeds the action level again after completing a 15-year replacement program. NR 809.545(3)(3) Individual service line considerations. A water supplier is not required to replace an individual lead service line if the lead concentration in all service line samples from that line, taken pursuant to s. NR 809.547 (2) (c), is less than or equal to 0.015 mg/L. NR 809.545(4)(4) Extent of service line replacement. A water supplier shall replace the entire service line, up to the building inlet, unless the water supplier demonstrates to the satisfaction of the department under sub. (5), that the public water system controls less than the entire service line. In such cases, the water supplier shall replace the portion of the line which the department determines is under the water supplier’s control. The water supplier shall notify the user served by the line that the water supplier will replace the portion of the service line under the public water system’s control and the water supplier shall offer to replace the building owner’s portion of the line, but is not required to bear the cost of replacing the building owner’s portion of the line. A water supplier is not required to bear the cost of replacing the privately-owned portion of the line, nor is the water supplier required to replace the privately-owned portion where the building owner chooses not to pay the cost of replacing the privately-owned portion of the line, or where replacing the privately-owned system would be precluded by department, local or common law. An water supplier that does not replace the entire length of the service line shall also complete all of the following tasks: NR 809.545(4)(a)(a) At least 45 days prior to commencing with the partial replacement of a lead service line, the water supplier shall provide notice to the residents of all buildings served by the line explaining that they may experience a temporary increase of lead levels in their drinking water, and shall provide guidance on measures consumers can take to minimize their exposure to lead. The department may allow the water supplier to provide notice under this paragraph less than 45 days prior to commencing partial lead service line replacement if the replacement is in conjunction with emergency repairs. In addition, the water supplier shall inform the residents served by the line that the water supplier will, at the public water system’s expense, collect a sample from each partially-replaced lead service line that is representative of the water in the service line for analysis of lead content, as prescribed under s. NR 809.547 (2) (c), no later than 72 hours after the completion of the partial replacement of the service line. The water supplier shall collect the sample and report the results of the analysis to the building owner and each resident served by the line no later than 3 business days after receiving the results. Mailed notices post-marked no later than 3 business days after receiving the results shall be considered timely. NR 809.545(4)(b)(b) The water supplier shall provide the information required by par. (a) to the residents of individual dwellings by mail or by other methods approved by the department. In instances where multi-family dwellings are served by the line, the water supplier may post the information at a conspicuous location likely to give notice to all residents of the multi-family dwellings. NR 809.545(5)(5) Accelerated schedule for service line replacement. The department shall require a water supplier to replace lead service lines on a shorter schedule than that required by this section, taking into account the number of lead service lines in the public water system, if a shorter replacement schedule is feasible. The department shall make this determination in writing and notify the water supplier of its finding no later than 6 months after the water supplier is required to begin service line replacement based on monitoring under sub. (1). NR 809.545(6)(6) Ceasing and recommencing service line replacement. Any water supplier may cease replacing lead service lines when lead service line samples collected pursuant to s. NR 809.547 (2) (b) meet the lead action level during each of 2 consecutive monitoring periods and the water supplier submits the results to the department. If the lead service line samples in any such public water system thereafter exceed the lead action level, the water supplier shall recommence replacing lead service lines, pursuant to sub. (2). NR 809.545(7)(7) Compliance reporting. To demonstrate compliance with subs. (1) to (4), a water supplier shall report to the department the information specified in s. NR 809.55 (5). NR 809.545 HistoryHistory: CR 09-073: cr. Register November 2010 No. 659, eff. 12-1-10. NR 809.546NR 809.546 Public education and supplemental monitoring requirements. All water suppliers shall deliver a consumer notice of lead tap water monitoring results to persons served by the public water system at sites that are tested, as specified in sub. (4). If a public water system that exceeds the lead action level based on tap water samples collected in accordance with s. NR 809.547, the water supplier shall deliver the public education materials contained in sub. (1) in accordance with the requirements in sub. (2). Water suppliers for public water systems that exceed the lead action level shall sample the tap water of any customer who requests it in accordance with sub. (3). NR 809.546(1)(1) Content of written public education materials for lead and copper control. NR 809.546(1)(a)(a) Content for community water systems and non-transient noncommunity water systems. Water suppliers shall include the following elements in printed materials, for example, brochures and pamphlets, in the same order as listed below. In addition, the language in subds. 1., 2., and 6. shall be included in the materials, exactly as written, except for the text in brackets in those subdivisions for which the water supplier shall include public water system-specific information. Any additional information presented by a water supplier shall be consistent with the information below and be in plain language that can be understood by the general public. Water suppliers shall submit all written public education materials to the department prior to delivery. The department may require the water supplier to modify the language before the department approves of the content of written public materials prior to delivery. NR 809.546(1)(a)1.1. IMPORTANT INFORMATION ABOUT LEAD IN YOUR DRINKING WATER. [INSERT NAME OF PUBLIC WATER SYSTEM] found elevated levels of lead in drinking water in some homes or buildings. Lead can cause serious health problems, especially for pregnant women and young children. Please read this information closely to see what you can do to reduce lead in your drinking water. NR 809.546(1)(a)2.2. ‘Health effects of lead.’ Lead can cause serious health problems if too much enters your body from drinking water or other sources. It can cause damage to the brain and kidneys, and can interfere with the production of red blood cells that carry oxygen to all parts of your body. The greatest risk of lead exposure is to infants, young children, and pregnant women. Scientists have linked the effects of lead on the brain with lowered IQ in children. Adults with kidney problems and high blood pressure can be affected, more than healthy adults at lower levels of lead. Lead is stored in the bones, and it can be released later in life. During pregnancy, the child receives lead from the mother’s bones while in utero, which may affect the child’s brain development. NR 809.546(1)(a)3.b.b. Explain possible sources of lead in drinking water and how lead enters drinking water. Include information on home and building plumbing materials and service lines that may contain lead. NR 809.546(1)(a)3.c.c. Discuss other important sources of lead exposure in addition to drinking water, for example, paint. NR 809.546(1)(a)4.4. ‘Reducing lead exposure.’ Discuss the steps the consumer can take to reduce their exposure to lead in drinking water. NR 809.546(1)(a)4.b.b. Explain concerns with using hot water from the tap and specifically caution against the use of hot water for preparing baby formula. NR 809.546(1)(a)4.d.d. Discuss other options consumers can take to reduce exposure to lead in drinking water, such as alternative sources or treatment of water. NR 809.546(1)(a)5.5. ‘Reasons for elevated lead levels and water supplier response.’ Explain why there are elevated levels of lead in the public water system’s drinking water, if known, and what the water supplier is doing to reduce the lead levels in homes and buildings in this area. NR 809.546(1)(a)6.6. For more information, call us at [INSERT YOUR NUMBER] [(IF APPLICABLE), or visit our Web site at [INSERT YOUR WEB SITE HERE]].
