An RIR is required at the beginning of the rulemaking process for rules recommending environmental standards or conditions. It documents the environmental and economic costs and benefits associated with the proposed rule changes. The department invites the public to review and submit comments to help ensure that our regulations provide required protections but do not add unneeded costs. Only the RIR is open for public comment at this time. The department will review all comments received at the end of the public comment period and post the comments and the department’s response in the Regulatory Action Tracking System before filing the proposed amendment with the Secretary of State. The proposed rule will be open for public comment at a later date.
The proposed rule amendment updates the lead free standard and federally required state enforcement actions. The department is proposing the amendment to incorporate federal rule revisions to §143 Subpart B - Use of Lead Free Pipes, Fittings, Fixtures, Solder, and Flux for Drinking Water into state regulation. The proposed amendment will revise the definition of lead free from 8% to 0.25% as a weighted average on wetted surfaces. It will also add a new section clarifying the requirement for community public water systems to have a mechanism in place for local enforcement of the lead ban. For additional details please view the rulemaking report.
