Lead and Copper and Your Water Service Lines

Who is required to submit service line inventories? 

All Community and Non-Transient Non-Community Water Systems are required to submit a lead service line inventory under the Lead and Copper Rule Revision (LCRR) per 40 CFR 141.84. LCRR requires water systems to prepare and maintain an inventory of service line materials.

When is the service line inventory due? 

The initial Lead Service Line Inventory was due October 16, 2024. The City is required to update this inventory annually beginning July 1, 2025.

With the new LCRI rules, the City will be starting on the baseline inventory due November 1, 2027. This is an expansion of the initial service line inventory already submitted.

What is the City of McCall doing to comply with the LCRR? 

Staff has compiled and submitted our initial lead service line inventory to DEQ.

Notifications have been sent to customers with “unknown”, “lead”, or “galvanized requiring replacement” water service lines.

Staff is now working on refining our inventory, working on a replacement plan, and additional lead sampling.

What are the types of service lines? 

Each service line must be classified using one of the four options listed below. Material classifications are required for both the system- and customer-side where ownership is split.

Lead: A portion of the pipe that is made of lead, which connects the water main to the building inlet.

Galvanized Requiring Replacement (GRR): A galvanized service line that is or ever was downstream of an LSL or is currently downstream of an unknown service line.

Non-Lead: The service line is determined not to be lead or GRR through an evidence-based record, method, or technique.

Unknown: The service line material is not known to be a lead, GRR, or non-lead, such as where there is no documented evidence supporting material classification.

What's happening now?

On August 4, 2022, EPA released Guidance for Developing and Maintaining a Service Line Inventory to support water systems with their efforts to develop inventories and to provide states with needed information for oversight and reporting to EPA. The guidance provides essential information to help water systems comply with the Lead and Copper Rule Revisions requirement to prepare and maintain an inventory of service line materials by October 16, 2024. Specifically, EPA’s Lead Service Line Inventory guidance:

  • Provides best practices for inventory development and communicating information to the public.
  • Includes a template for water systems, states, and Tribes to use or adapt to create their own inventory.
  • Contains case studies on developing, reviewing, and communicating about inventories.
  • Highlights the importance of prioritizing inventory development in disadvantaged communities and where children live and play.

EPA is harmonizing regulatory requirements with unprecedented funding through President Biden’s Bipartisan Infrastructure Law to make rapid progress on removing harmful lead from America’s drinking water.   


Revisions to the Lead and Copper Rule

EPA’s new Lead and Copper Rule better protects children and communities from the risks of lead exposure by better protecting children at schools and child care facilities, getting the lead out of our nation’s drinking water, and empowering communities through information. Improvements under the new rule include:

  • Using science-based testing protocols to find more sources of lead in drinking water.
  • Establishing a trigger level to jump-start mitigation earlier and in more communities.
  • Driving more and complete lead service line replacements.
  • For the first time, requiring testing in schools and childcare facilities.
  • Requiring water systems to identify and make public the locations of lead service lines

Lead and Copper Rule Improvements - Summary

When did Idaho ban lead in water lines? 

Idaho’s accepted lead ban was effective 8/11/1988. If a home was built within a year after this date, additional information is required to verify that lead was not utilized.

Is there a timeline for replacing these lines? 

The current Lead and Copper Ruling states that in 10-years all non-compliant service lines need to be replaced.

Lead and Copper Frequently Asked Questions
How Does the City know what my service line type is?

Staff is working through building records and plans that constructed our water infrastructure. Some areas of town are lacking records of the construction that occurred which will require additional effort from staff and the community to fill in the blanks.

Generally, if a home was constructed prior to 1988, the likelihood of a service line containing lead, lead solder, or a galvanized material is high.

In areas where the City is still missing information on service line material, we have been using vac-truck exploration to visually verify the material type.

Water sampling can also help Staff identify if a service line may contain lead. However, internal plumbing contributes to this result.

Will the Public be able to see this inventory?

Yes! The inventory is uploaded on this website [link] and can be found physically at the Public Works Office at 815 N Samson Trail.

The website will also contain an interactive GIS map for customers to use to visualize the inventory and  other information related to the lead and copper rule.

I received a letter from the City regarding my water service line what now?

Please read through our website and if you have any additional questions, please reach out to us, Lead&Copper@mccall.id.us, (208)-634-3610

Owners will receive annual letters regarding their service line materials until they are replaced with a compliant material.

I have a lead or galvanized requiring replacement service line. What does this mean for me?

The property owner is required to notify the Water Department if they are replacing their non-compliant service line. This notification will start the process on the Water System side to work with the owner on replacing the whole service line to a compliant material.

I know I replaced my water line, and the inventory shows “unknown”. What do I do?

Please fill out the form titled “Incorrect Service Line Material”. There is likely more information needed prior to officially changing the classification in our inventory.

Overall classifications for the service lines are affected by both the Public Water System side and the Customer Side. If either, or both sides are “unknown”, the overall classification is deemed “unknown”.

How is the City funding replacements?

The City is currently adjusting their long-range capital improvements plan to prioritize replacing all galvanized mains and service lines (between the main and the meter).  The City is also exploring and applying for any available grant funding to help minimize the impact of these replacement costs on water rates

More information is forthcoming from EPA on how water utilities can manage replacement responsibilities and costs for non-compliant privately owned water service lines (the portion of the service line between the meter and the structure).  Per the City’s current policy, replacement of non-compliant private service lines is the financial responsibility of the property owner/customer.  However, the City is actively engaged with the Idaho Department of Environmental Quality (IDEQ) to better understand funding that may be available for private service line replacement.

Water Sampling

The City of McCall performs water quality sampling once a month. If you have not had your home sampled for lead, please fill out the form titled “Lead and Copper Sampling Request”.
