Lead pipe replacement law in North Dakota
North Dakota has not set its own state-specific lead service line replacement deadline beyond the federal requirement below. The rule is implemented through the North Dakota Department of Environmental Quality, which required every public water system to submit a baseline inventory by October 16, 2024 under the federal Lead and Copper Rule Improvements, rather than setting an earlier state-specific replacement date.
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 North Dakota coverage
Williston and West Fargo are not covered here -- neither has a public address-searchable material inventory found (Williston has no public-facing map at all; West Fargo has only a resident self-report survey form and generic infrastructure layers with no material field). A "not found" result for an address in either area means unpublished here, not confirmed lead-free.
