Lead Service Line Replacement and Notification Act (HB 3739)

8/27/2021 signed by Governor, effective date 1/1/2022

The Act creates a low-income water assistance policy and program as well as the Lead Service Line Replacement Fund in the State Treasury to be used by the Agency and the Department of Commerce and Economic Opportunity. The Fund will finance and administer programs and activities associated with identifying and replacing lead service lines and to build Agency capacity. The bill bans partial replacement of lead service lines. Beginning January 1, 2022, a lead in drinking water protection fee will be imposed on billed water usage based on census tract median income. Through financial resources provided by the Fund, the Agency will make available grants to community water suppliers to replace lead service lines. Initial lead service line replacement plans must be submitted by April 2024. The Act also creates a Lead Service Line Replacement Advisory Board to oversee the operation and administration of these programs. According to IEC“every municipality in Illinois will be required to develop and execute a plan that inventories, removes and replaces ALL lead service lines while prioritizing replacement in our most vulnerable communities.”
