LCRR Requirements

Lead Service Line Inventory (LSLI), Replacement and Sampling Plans

The Lead and Copper Rule Revisions (LCRR) require all community water systems and non-transient non-community water systems to develop and submit to NHDES an inventory of service line materials and a proposed replacement plan for any lead and galvanized piping, for both utility and customer-owned sections. Each water system whose inventory has lead and/or galvanized piping is required to submit annual updates to NHDES. Based on the inventory results, new sampling sites must be proposed in accordance with the LCRR new sampling tiers.

Inventory information must be submitted to NHDES by the federal deadline of October 16, 2024. The Lead Service Line Inventory Template is the required format to submit inventory information and submittals can be sent anytime prior to the deadline to dwlead@des.nh.gov.
