The Lead-Free DC Omnibus Amendment Act of 2025 mandates the complete replacement of all lead service lines in the District of Columbia by December 31, 2030, prohibiting partial replacements and the installation of new lead, brass, or galvanized steel service lines. Property owners with lead service lines must enroll in the Lead Service Line Replacement Program or replace the lines themselves by October 1, 2024. The bill establishes protocols for testing service lines, public education requirements, and prioritizes replacements for vulnerable facilities. It also requires the Department of Energy and Environment to engage community organizations for oversight and sets penalties for non-compliance.

Additionally, the bill mandates the District of Columbia Water and Sewer Authority (DC Water) to implement a comprehensive Lead Service Line Replacement Program at no cost to property owners, notify them of lead service lines, and maintain an inventory of service lines. It includes provisions for public education on lead exposure risks, requires landlords to reimburse tenants for relocation during replacements, and prohibits rent increases related to these costs. The legislation also establishes a nonlapsing Lead Service Line Priority Replacement Assistance Fund and mandates annual reporting on the status of lead service line replacements, enhancing transparency and accountability in the management of lead service line issues.
