Lead Service Line Inventories in Wyoming and on Tribal Lands in EPA Region 8
Getting Started
Service line inventories are the foundation from which water systems take action to address a significant source of lead in drinking water – lead service lines (LSLs). Establishing an inventory of service line materials and identifying the location of LSLs is a key step in getting them replaced and protecting public health.

Federal Service Line Inventory Requirement
The Lead and Copper Rule Revisions (LCRR) requires all Community Water Systems (CSW) and Non-Transient, Non-Community Water Systems (NTNCWS) to prepare and maintain an inventory of service line materials. Initial service line inventories for Wyoming and Region 8 Tribal water systems are required to be submitted to EPA Region 8 by October 16, 2024.
Required and Recommended Inventory Elements
A service line inventory must include:
- All service lines, regardless of the actual or intended use.
- Service line material classification for the entire service line (i.e., lead, galvanized requiring replacement (GRR), non-lead, or lead status unknown).
- Material classifications for both the system-side and customer-side where ownership is split.
- Location identifiers for lead and GRR service lines (e.g., street address).
EPA recommends that a service line inventory also:
- Include detailed location identifiers for all service lines;
- Add sub-classifications of service line materials;
- Include lead connectors where data are available;
- Track other drinking water infrastructure components potentially containing lead; and
- Document additional service line characteristics.
Regulatory Information
Service Line Inventory Guidance, Template, Fact Sheets and FAQs
There are several EPA websites that contain links to documents for developing and maintaining a lead service line inventory. See Related Resources in the sidebar. These key documents are also available at the links below and include EPA’s Service Line Inventory Guidance and Template, Small Entity Compliance Guide, Fact Sheet for Developing a Service Line Inventory, LCRR FAQs and LCRR Implementation Fact Sheet. Please look below or go to the websites in the sidebar to download the following documents:
Guidance for Developing a Service Line Inventory and Service Line Inventory Template
EPA’s Guidance for Developing and Maintaining a Service Line Inventory supports water systems with their efforts to develop initial service line inventories and provides primacy agencies with needed information for oversight and reporting. The guidance provides essential information to help water systems comply with the 2021 Lead and Copper Rule Revisions (LCRR) requirement to prepare and maintain an inventory of service line materials by October 16, 2024. There is also an associated Inventory Template.
Small Entity Compliance Guide
EPA’s Developing and Maintaining a Service Line Inventory: Small Entity Compliance Guide supports water systems, particularly small water systems, in complying with the 2021 Lead and Copper Rule Revisions (LCRR) initial service line inventory requirements. EPA’s Small Entity Compliance Guide helps explain the initial inventory-related actions small community and non-transient non-community water systems are required to take under the LCRR.
Fact Sheet for Developing a Service Line Inventory
EPA’s Fact Sheet for Developing and Maintaining a Service Line Inventory can help water systems quickly identify the key 2021 LCRR initial service line inventory requirements, including inventory elements, planning, records review, investigations, public accessibility, and information for non-lead systems.
LCRR FAQs for Water Systems
These Frequently Asked Questions (FAQs) address the provisions of the 2021 Lead and Copper Rule Revisions (LCRR) that EPA has proposed to retain starting on the October 16, 2024, compliance date. These requirements include the initial service line inventory, notification to persons served of known or potential lead service line, Tier 1 public notification of a lead action level exceedance, and associated reporting requirements.
2021 LCRR Implementation Fact Sheet
EPA’s 2021 LCRR Implementation Fact Sheet describes the 2021 Lead and Copper Rule Revisions (LCRR) requirements that public water systems must comply with starting on October 16, 2024, as outlined in the Proposed Lead and Copper Rule Improvements (LCRI). These requirements include the initial service line inventory, notification to persons served of known or potential lead service line, Tier 1 public notification of a lead action level exceedance, and associated reporting requirements.
Service Line Inventory Technical Assistance
EPA’s LSLI Technical Assistance Contract for Tribal Public Water Systems
EPA Region 8 has contracted with the Oneida Total Integrated Enterprises and CH2M Joint Venture (OCH JV) to offer free technical assistance to eligible Tribal public water systems for development of initial service line inventories. OCH JV can assist eligible Tribal water systems with reviewing existing records, listing all service connections, assigning location identifiers, completing EPA’s Service Line Inventory Template, and submitting the initial service line inventory to EPA. For more information about the project, check the links below or contact TribalCommunityLSLI@jacobs.com.

Wyoming LSLI Technical Assistance Program for Wyoming Public Water Systems
WY RISK IT? The Wyoming Lead Service Line Project is the State of Wyoming’s free lead service line technical assistance program for eligible Wyoming public water systems. The Wyoming Lead Service Line Project website includes a survey for water customers to determine what type of water service line they have in their homes along with additional information and resources. The site also provides water systems with resources to participate in the Wyoming Lead Service Line Project. For more information about the program, visit the website or contact wyomingLSL@hdrinc.com.
