The Louisiana Environmental Laboratory Accreditation Program is designed to ensure the accuracy, precision, and reliability of the data generated, as well as the use of the department-approved methodologies in the generation of that data. Laboratory data generated by commercial environmental laboratories that are not accredited under these regulations will not be accepted by the department in accordance with LAC 33:I.4501.A.2. Whenever samples are subcontracted to another environmental testing laboratory, the original laboratory shall maintain a verifiable copy the results with a chain of custody. The procedure may not be used to circumvent proper accreditation or any state requirements. The original laboratory is responsible for ensuring that the secondary laboratory used is properly accredited for the scope of testing performed in accordance with LAC 33:I.5307.D.

- Fugitive Emission Testers - Fugitive emission testers performing EPA Method 21 only and no other analyses are not required to be accredited by the Louisiana Environmental Laboratory Accreditation Program at this time.
- LELAP is publishing the laboratory records in the Electronic Data Management System (EDMS). EDMS is the system for LDEQ’s electronic repository of official records that have been created or received by the Department. Use the AI number of the lab in the above lists to search LDEQ’s Electronic Data Management System (EDMS) to find and review a lab’s current Certificates and Scopes of Accreditation. Data generated by an accredited lab to be submitted to the Louisiana Department of Environmental Quality is limited to the method/parameters listed on their current Scope of Accreditation (follow regulation links below for specific information). To use EDMS go to http://edms.deq.louisiana.gov/app/doc/querydef.aspx EDMS users need to create an account in EDMS if they are not already a registered user. The direct link to EDMS is http://edms.deq.louisiana.gov. Once there, users may click on the Create Account link on the left side of the page. LELAP recommends visiting the HELP page on the left side of the screen. It provides helpful information in navigating the system.
