Bulk liquid terminals and tank farms move product through loading racks, pumps, and valve manifolds, and store it in tanks that breathe. Between gasoline-distribution rules, storage-vessel NSPS, and vapor recovery, the leak points are everywhere. AIM™ EH&S runs LDAR for terminals and tank farms — the racks, the manifolds, and the tanks.
Which Rules Apply at Terminals & Tank Farms
Bulk gasoline terminals fall under NSPS Subpart XX and the gasoline-distribution NESHAP (40 CFR 63 Subpart R for major sources, Subpart BBBBBB for area sources), with loading-rack vapor-recovery and component-monitoring requirements. Storage vessels fall under NSPS Subparts Kb and OOOO, including floating-roof seal inspections. We map the applicable subparts to your racks, pumps, and tanks.
What We Do
Method 21 monitoring of loading-rack and manifold components, pump and valve LDAR, floating-roof and seal-gap inspections, leak repair tracking, recordkeeping, and report preparation — for a single terminal or a multi-site tank-farm network.
Why Terminal Operators Call Us
We know where terminals leak — the rack, the loading arms, the pump seals — and we document it defensibly. No fluff, no missed components.
Terminal & Tank Farm LDAR FAQs
What rules govern gasoline terminals?
Bulk gasoline terminals are covered by NSPS Subpart XX and the gasoline-distribution NESHAP (Subparts R and BBBBBB), which set loading-rack vapor-recovery standards and equipment-leak monitoring. See our LDAR compliance overview.
Do you inspect storage tank seals?
Yes — floating-roof tanks under NSPS Subparts Kb and OOOO require seal-gap inspections on a set schedule, and we perform them alongside component LDAR.
Do you cover loading-rack components?
Loading racks are a primary leak source — arms, couplers, valves, and pumps. We run Method 21 on all of it and track repairs against the clock.
Which regions do you cover?
Nationwide, with strong coverage along the Gulf Coast, Texas, and Florida terminal corridors. See all regions we serve.
