Lead Detection & Repair (LDAR) Support Services FAQ

Leak Detection and Repair (LDAR) programs are regulatory requirements designed to identify and control fugitive emissions of Volatile Organic Compounds (VOCs) and Hazardous Air Pollutants (HAPs) from equipment components such as valves, pumps, connectors, pressure relief devices, agitators, compressors, instrumentation systems, and sampling connection systems.

Facilities subject to NSPS (e.g., Subparts VV/a/b, GGG/a, KKK, OOOO/a/b/c), NESHAP (e.g., Subparts F, J, V, FF), MACT standards (e.g., Subparts H, I, S, CC, DD, HH, SS, TT, UU, YY, GGG, MMM, EEEE, FFFF, VVVVVV), RCRA Subparts BB and CC, and similar state-specific requirements often require LDAR programs to ensure compliance.

We provide gap assessments, applicability reviews, emission calculations, quarterly quality assurance/quality control reviews, program & strategy development, and field implementation support. Our experts also guide equipment selection, train facility staff, and integrate advanced monitoring tools for better data management.

Yes. We conduct a variety of third-party audits ranging from desktop review to full week on-site review to help clients evaluate compliance status, identify areas for program improvement, and demonstrate adherence to regulatory requirements and agreements between regulatory agencies and facilities (e.g Consent Decrees, Consent Agreement and Final Orders).
