LEAK DETECTION AND REPAIR SERVICES (LDAR)
40 CFR Part 60 Subpart OOOOa of the New Source Performance Standards establishes emissions standards and compliance schedules for the limitation of emissions from methane, a pollutant greenhouse gas (GHG). It also establishes emissions standards and compliance schedules for the control of volatile organic compounds (VOCs) and sulfur dioxide (SO2) emissions from affected facilities in the crude oil and natural gas source category.You are subject to QUAD Oa if you are the owner or operator of one or more onshore affected facilities which commenced construction, modification, or reconstruction after September 18, 2015. Of the affected facilities, well sites and compressor stations are required to survey all of their fugitive emission components, per §60.5397a of Subpart OOOOa. The surveys are required in order to identify leaking components, document the leaks, and repair the emission leaks from fugitive components. The goal is for each affected facility to reduce methane emissions and VOC emissions by monitoring their fugitive emissions components.
- An initial monitoring survey must be completed within 60 days of start-up (of production at a well site or the start-up of a compressor at a compressor station), modification or reconstruction for each collection of fugitive emissions components from a well site or a compressor station or by June 3, 2017, whichever is later
- After June 3, 2017, an initial monitoring survey must be completed within sixty (60) days of start-up, modification, or reconstruction of a collection of fugitive emissions components at a new well site or pre-existing QUAD Oa affected well site
- For each new well drilled or one that is hydraulically fractured after June 3, 2017, that sends liquids to a pre-existing QUAD Oa affected well site, an initial survey of fugitive emission sources will be required to be conducted within thirty (30) days of start-up
- The frequency of the monitoring survey of each collection of fugitive emissions components at a well site within a company-defined area must be conducted at least semi-annually
- The frequency of the monitoring survey of each collection of fugitive emissions components at a compressor station within a company-defined area must be conducted at least quarterly after the first initial survey
- Any fugitive leak(s) that are discovered must be repaired or replaced as soon as practicable but no later than thirty (30) calendar days from discovery
- A resurvey of the repaired or replaced fugitive emissions source(s) must be completed as soon as practicable but no later than thirty (30) calendar days from the repair date
- Recordkeeping is required for 5 years
- Annual reporting is required
OTA Compression offers services that cover fugitive emissions component surveying, repairing, and documenting. Our Leak Detection and Repair program will keep your facility in timely compliance with these new regulations. OTA’s LDAR stands out among others because it utilizes the only EPA certified optical gas imaging (OGI) camera, e.g. FLIR GF3xx series, to survey your affected facility’s fugitive emissions components in order to visualize and pinpoint leaks without the need to shut down operations at the site. Additionally, OTA will have a repair technician present during the survey. This enables us to pinpoint, repair, and re-survey the repaired fugitive emissions components on the same day reducing your cost and relieving the wait time for submitting reports. The documenting of any leaks and repairs will be captured within the Leak Detection and Repair (LDAR) report that we can generate on your behalf. OTA’s LDAR report will contain vital information that will allow you to encounter a painless and uncomplicated annual reporting event to the EPA. Per §60.5397a, owners or operators of affected sources must develop a monitoring plan that serves as the blueprints for the surveyor, and includes but not limited to: calibration protocols, observation paths, survey techniques, survey equipment and designs, and leak source descriptions. OTA is well versed in monitoring plans and can assist you in the development. In fact, we have a monitoring plan ready for distribution. OTA Compression’s LDAR program can help you successfully navigate through the new regulations requiring fugitive component monitoring, repairing, and reporting requirements set forth by 40 CFR Part 60 Subpart OOOOa §60.5397a.
OTA’s personnel are Certified Gas Imaging Thermographers by the Infrared Training Center (ITC) or are trained, directed, and supervised by a certified technician. Most of our LDAR technicians have surveying experience that comes from surveying hundreds of oil and gas production sites.
