<summary>The Environmental Protection Agency (EPA or Agency) is announcing the availability of the document titled "Laboratory Quality Standards for Recognition (LQSR 4.0)" under the National Lead Laboratory Accreditation Program (NLLAP), which is a revision to the EPA document titled "Laboratory Quality System Requirements (LQSR) Revision 3.0," dated November 5, 2007. The revised LQSR 4.0 updates and streamlines the guidance by referencing existing laboratory standards already in practice by NLLAP participating laboratories and directly related to laboratory lead analysis; and includes updates to the test and sampling method standards to better complement EPA's lead- based paint program activities.</summary>
<dates>LQSR 4.0 is effective October 23, 2024. However, in order to be recognized by the NLLAP, laboratories and accreditation organizations that currently administer the NLLAP can comply with the standards of LQSR 3.0 or LQSR 4.0 until December 22, 2025. After December 22, 2025, all NLLAP-recognized organizations must implement and comply with the standards of LQSR 4.0 in order to maintain participation in NLLAP.</dates>
