The Delaware Basin runs hot — high gas-to-oil ratios, sour service, and pad density that puts thousands of components under federal monitoring rules. AIM™ EH&S runs Leak Detection and Repair (LDAR) programs across the West Texas and southeast New Mexico side of the Permian, built by people who have actually walked the unit.
Which Rules Apply in the Delaware Basin
Most upstream and midstream sites here fall under NSPS OOOOa, OOOOb, and the OOOOc emissions guidelines, depending on construction and modification dates. Older facilities may still carry SOCMI or refinery subpart obligations. We read the applicable subpart for your specific site rather than applying a one-size template — the leak definition, monitoring frequency, and repair clock all change with it.
What We Do Out Here
Method 21 monitoring on valves, pumps, connectors, and pressure relief devices. Optical Gas Imaging (OGI) surveys where the subpart allows or requires it. First-attempt and final repair tracking against the regulatory clock. Recordkeeping that survives an EPA audit, not just a clipboard. Program design and gap assessments for new pads coming online.
Why Operators in the Permian Call Us
Remote pads, long drives, and tight turnaround windows are the norm in the Delaware Basin. We schedule around your operations, show up with calibrated instruments, and hand you defensible data — not excuses. No marketing fluff, no padded headcounts.
