NR 809 Lead and Copper Update

The state's safe drinking water code NR 809 will be revised to include updates to lead and copper standards.

The intent of proposed rule DG-04-24 is to update ch. NR 809, Wis. Adm. Code (related to control of lead and copper in public drinking water) to be consistent with 2021 revisions to the Federal Lead and Copper Rule, 40 CFR 141.80 to 141.93, with the anticipated October 2024 federal rule revision – Lead and Copper Rule Improvements and other federal laws addressing lead and copper in public drinking water.

The Federal Lead and Copper Rule Revisions (LCRR) went into effect on Dec. 16, 2021, with a compliance date of Oct. 16, 2024. The Federal Lead and Copper Rule Improvements (LCRI) were published in the Federal Register on Oct. 30, 2024, with a compliance date of Nov. 2027. To avoid the inefficient adoption of multiple rules over a short period of time, the EPA recommends that states group the promulgation of the LCRR and LCRI requirements into a single action.

Rulemaking Procedures

Rule change process, public input and timeline

The DNR creates and revises administrative rules to implement statutes enacted by the Wisconsin State Legislature [exit DNR]. Administrative rules have the full force and effect of law.

Rulemaking is an extensive process and there are many internal steps [PDF] that the DNR and the NRB must follow during a rulemaking effort. Public participation is a critical component of agency rulemaking, and there are numerous opportunities to participate in the DNR rulemaking process. For permanent rules, the entire process generally takes about 31 months from initiation to effective date of rule revisions.

Public Comment Opportunities

Public meetings and hearings

There will be multiple opportunities for anyone interested in the process to provide input at public meetings. Notifications will be sent out via GovDelivery and links to these meetings will be posted on this webpage when available.
