Lead pipe replacement law in Wyoming
Wyoming has not set its own state-specific lead service line replacement deadline beyond the federal requirement below. Wyoming has not taken primacy for this program under the Safe Drinking Water Act, so the EPA's Region 8 office administers the federal Lead and Copper Rule Improvements directly; every public water system was required to submit a baseline inventory by October 16, 2024. The Wyoming Department of Environmental Quality provides technical assistance to water systems (including a resource hub at wyriskit.com) but has not imposed an earlier or stricter state deadline.
Separately from any state law, the EPA's federal Lead and Copper Rule Improvements require every water system nationwide to submit a baseline inventory and an approved replacement plan by November 1, 2027, then fully replace all lead and "galvanized requiring replacement" lines under its control on a schedule of 10 years or less from that date, replacing at least 10% of its known lead/GRR lines per year. A narrow exception allows a longer schedule only for the roughly 1% of systems with an unusually dense concentration of lead lines, and partial (non-emergency) replacements are prohibited.
Known gaps in Wyoming coverage
Laramie is not covered here -- it has real, confirmed internal per-address lead service line inventory data (per an Esri case study describing the city's own use of ArcGIS Field Maps and the official "Lead Service Line Inventory" solution), but nothing was found publicly exposed after an exhaustive search. Cheyenne, the state capital and largest city, was investigated in depth: its public map is real and live, but no layer combines an address field with a material classification -- a dead end by how it was built, not by access restriction. A "not found" result for a Laramie or Cheyenne-area address means unpublished here, not confirmed lead-free.
