Fugitive emissions from process equipment — valves, flanges, connectors, pumps, compressors, and pressure relief devices — represent both environmental compliance risk and economic waste. MAC Safety's Leak Detection and Repair (LDAR) services deploy certified technicians with optical gas imaging (OGI) cameras and EPA Method 21 monitoring equipment to systematically survey regulated components, identify leaks, and manage repair verification in compliance with 40 CFR Part 60, Part 63, and applicable state regulations.
MAC Safety's LDAR programs cover initial component inventories and tagging, quarterly/semi-annual/annual monitoring surveys per applicable subpart requirements, delay-of-repair tracking, first and final attempt repair documentation, and regulatory reporting for LDAR compliance. Optical gas imaging provides rapid screening capability for large component populations, while Method 21 monitoring with calibrated organic vapor analyzers provides the quantitative leak measurements required by regulation.
LDAR monitoring data feeds into the NIXN platform, creating compliance records that support EPA audit readiness and demonstrate continuous improvement in fugitive emissions performance. When combined with continuous emissions monitoring system (CEMS) data and process safety management documentation, LDAR data completes the emissions compliance picture that regulators and corporate sustainability programs require.
