Lead and Copper Rule Revisions and Service Line Inventories

EPA Lead and Copper Rule Revisions published in 2021 include new provisions and changes to the Lead and Copper Rule (LCR). Public water systems now must identify and make public the locations of lead, non-lead, and unknown service lines through a lead service line inventory.

The effective date of the LCR revision has been delayed by the EPA until October 16, 2024.

The LCR revisions will support near-term actions to reduce lead in drinking water, including as the development of lead service line inventories by public water supply systems. The EPA will also develop new rules to strengthen key elements of the LCR revisions. The agency anticipates finalizing the forthcoming Lead and Copper Rule Improvements (LCRI) prior to October 16, 2024 (the current compliance date for the LCR revisions).

(This information is current as of March 2022.)

Lead Service Line Inventory Templates

Lead service line inventory templates for public water systems in Mississippi are now available from the MSDH Bureau of Public Water Supply. These templates include information required by the Lead and Copper Rule Revision (LCRR) and Improvements (LCRI).

All public water supply systems that are classified as community water systems (CWSs) and non-transient non-community (NTNC) water systems are required to submit their lead service line inventories to the Bureau of Public Water Supply by October 16, 2024.

Following the revised information provided through the LCRI, we have modified the existing templates down to just two versions. This allows for some simplification while still capturing the needed information for your service line inventory. System sizes below are based on the number of connections of your system.

Inventory Templates

These templates satisfy the service line inventory information collection needs for the public water system required by the Lead and Copper Rule Revisions and its recent Improvements to determine the service line classification.

Training and Guidance Resources

National Lead Ban

In 1986, Congress amended the SDWA to prohibit the use of pipes, solder or flux that are not “lead-free” in public water systems or plumbing in facilities providing water for human consumption. At the time, lead-free was defined as solder and flux with no more than 0.2 percent lead, and pipes with no more than 8.0 percent lead.

In 1996, Congress further amended the SDWA to prohibit the use of pipe and plumbing fittings and fixtures that are not lead-free in the installation and repair of any public water system or plumbing in a facility providing water for human consumption. The 1996 amendments also required lead-free plumbing fittings and fixtures (endpoint devices) to be in compliance with a lead leaching standard. States were required to enforce the lead ban by June of 1988.

Lead Bans and Lead Service Line Inventories

If a home was constructed after 1988 in Mississippi, it is expected that the service line for that home was constructed using material(s) other than lead. Public water systems developing their lead service line inventories may designate homes built after 1988 as not having a lead service line in their inventory.

Local ordinances or codes may also provide a time frame that can be used in service line material determinations.
