LDAR

LDAR & OGI

LDAR is an integral part of operator compliance.  Previously exclusive to midstream and downstream operations, Quad O’s lower thresholds have introduced the monitoring process to upstream ventures.  As states continue to adopt increasingly strict standards for compliance, Amerigo is there to help.

Amerigo knows optical gas imaging (OGI)/EPA Method 21 and we know upstream facilities and tank batteries. With increasing tank monitoring and facility inspections requirements, regulatory agencies are taking initiative to inspect facilities and assess compliance. Utilize Amerigo’s emission management program to ensure compliance and best management practices to maintain air pollution control.

Amerigo’s emission managment program includes:

• Certified thermographers utilizing FLIR GF 320 cameras or EPA Method 21
• Daily reports with footage
• Experience understanding state and federal tank regulations (CO Regulation 7, NSPS Quad O)
• Compliance plan ready for integration to client operations (CO Regulation 7 STEM Plan)
• Database to trend findings and manage repairs

Click the each state to review regulations impacting our industry.

  • Regulation Number 7 regulates methane emission from the oil and gas industry
  • Requires traditional Method 21 and/or Approved Instrument Monitoring Method (AIMM) monitoring of Storage Tanks
  • Requires LDAR programs at natural  gas compressor stations and well production facilities; LDAR can include both Method 21 and infrared camera technology
  • 500 ppm leak threshold at all applicable well production facilities
  • General Permits GP 12.1 and 12.2 require LDAR programs with a general leak definition of 10,000 ppm
  • Method 21 or optical gas imaging (IR) can be utilized
  • Leak performance can reduce monitoring frequency
  • General Permit GP-5
  • LDAR required at any natural gas processing facility that produces, compresses and/or processes natural gas, coal bed methane coal mine gob starting with gas fractionation, dehydration, compression and storage
  • IR surveys also required within 180 days of startup and quarterly thereafter
  • Presumptive BACT in three specific concentrated development areas:
  • Upper Green River Basin
  • Normally Pressured Lance
  • Jonah and Pinedale Anticline Development
  • LDAR required for all facilities with ≥4 VOCs tpy and operating in the above concentrated areas
