The USEPA Lead and Copper Rule Revisions (LCRR) require water systems to create, maintain, and submit inventories that include all service line materials in the distribution system, including both customer and utility owned service lines. Each service line and/or sides of the service line must be classified as: lead (LSL), galvanized requiring replacement (GRR), non-lead, or lead status unknown (unknown). The Public Water Systems must make a portion of their inventory publicly available. More information can be found at USEPA Service Line Inventory Guidance. North Ridgeville’s current inventory list can be found below.
