Summary of New EPA Dust Lead Rule – NLLAP LQSR 4.0

Below is a summary of the Federal Register publication on October 23, 2024 for the new EPA Lead Dust Rule in conjunction with the EPA NLLAP LQSR (Laboratory Quality System Requirements) Revision 4.0 published the same day.

• New terminology: the Dust Lead Clearance Level (DLCL) is now the Dust Lead Action Level (DLAL) and the Dust Lead Hazard Standard (DLHS) is now the Dust Lead Reportable Limit (DLRL).
• FLAA analysis can still be utilized if we are provided a minimum wipe area of 288 in² (2 ft² ) for floors and 36 in² (0.25 ft² ) for windowsills. If not, we may have to utilize ICP-OES to achieve the new DLAL values with higher costs and longer Turnaround Times.
• Any result reported below the lab’s DLAL, but above the DLRL, triggers a requirement that the contractor must declare in their report that a lead hazard has been identified, even though the project is considered complete.
• Use of EMSL provided Ghost Wipes and Centrifuge Tubes is strongly encouraged to avoid additional sample prep fees.
