The department estimates that approximately 3400 hours of staff time will be required to complete the proposed rule.
6. List with description of all entities that may be affected by the proposed rule:
— Municipal community water systems (cities, townships, sanitary districts)
— Other-than-municipal community water systems (mobile home parks, apartment buildings, condominium associations)
— Non-transient non-community water systems (small businesses with 25 or more employees that are not on a municipal source)
— Wisconsin Department of Natural Resources
— Wisconsin Department of Health Services
— Wisconsin Public Service Commission
— Wisconsin Department of Safety and Professional Services
— Treatment installation businesses
— Consumers of water from Wisconsin public drinking water systems
7. Summary and preliminary comparison with any existing or proposed federal regulation that is intended to address the activities to be regulated by the proposed rule:
The Wisconsin rule is intended to correlate to federal regulation related to control of lead and copper, to be consistent with 2021 Lead and Copper Rule Revision, 40 CFR 141.80 to 141.93, and with the anticipated 2024 federal rule revision – Lead and Copper Rule Improvements, as described in #3 above. 8. Anticipated economic impact of implementing the rule (note if the rule is likely to have an economic impact on small businesses):
The implementation of LCRR is likely to realize significant health benefits, such as reducing incidences of preterm birth, hypertension and coronary heart disease; and improving cognitive function in children. Furthermore, implementation of the LCRR is expected to result in significant non-health benefits as well, such as reducing corrosion damage to drinking water and wastewater infrastructure. A study published in the July 15, 2023 issue of Environmental Research found the benefit-cost ratio of national implementation of LCRR to be 35:1 underscoring the importance of the rule revision. Preliminary analysis suggests the rule may have a significant economic impact if the LCRI includes a requirement for full LSL replacement. The extent of the economic impact will depend on changes to the federal rule, which are anticipated to happen during the early phases of this rulemaking process. The impacts will be evaluated in more detail during development of the economic impact analysis for the rule.
9. Anticipated number, month and locations of public hearings:
The department anticipates holding one public hearing in the month of June 2025. The department will hold the hearing virtually to allow for as many people to attend as possible.
