Navigate Compliance Effortlessly with the AURA OGI™ camera: Appendix K & OOOO

At ChampionX Emissions Technologies, we're committed to simplifying compliance efforts, and AURA OGI™ is your trusted tool for navigating the complexities of the Environmental Protection Agency’s (EPA) 40CFR Part 60 – Appendix K and the new OOOO regulations (OOOOb and OOOOc). While OOOOb & OOOOb rules define "why" we conduct surveys, their frequency, and what to look for, Appendix K is the "how" of conducting OGI surveys

Appendix K applies to upstream and downstream operations, including facilities such as, well-heads, compressor stations, refineries, and more. It focuses on detecting Volatile Organic Compounds (VOCs), not just methane. Many sites that used to have allowances under OOOOa no longer have those privileges under OOOOb. The main point to remember is that with OOOOb and 0000c, the number of required surveys will be double.

The camera must meet specific requirements, like detecting 17 grams per hour of butane, 18.5 grams per hour at a two-meter viewing distance, and a temperature change of five degrees Celsius. This helps identify leaks of certain sizes under specific conditions. AURA OGI meets all these requirements.

The survey process includes setting up the camera, mapping the route, and deciding how long to inspect each piece of equipment. The key idea here is to establish a traceable route to ensure consistency. Operators often have their own individual approaches and changes from person to person. Operators must take a break of at least 5 minutes after every 20 minutes of surveying. The AURA OGI ensures uniformity, and accuracy for audit purposes.

When equipped with AURA OGI™ base station, real-time wind data (using the attachable anemometer) ensures the most optimal conditions for surveying. The smart routing program of AURA OGI™ allows you to carefully map out and track the most efficient route. Any technician who uses our app can follow the same route and stand in the exact same spot for the survey. The app will also allow users to know how long to inspect each component and an icon on the app will change color on the screen once complete. Each leak found needs to be recorded for 10 seconds. The date, location, and time are all embedded into the frame as metadata

All camera operators must attend an annual classroom training refresher. New operators must undergo training, gaining 50 sites of experience through mentorship from a senior operator with at least 500 surveys completed to conduct solo surveys.

Operators can use the AURA OGI tablet or their own device to see what their partner sees in real-time. There's also a classroom session to teach operators about OGI technology, Appendix K, and their responsibilities.

These requirements include recording 5-minute videos explaining survey techniques and procedures, as well as tagging for repairs, to enhance the accuracy and documentation of emissions surveys.  


The AURA OGI™ can streamline this entire process at the push of a button.

  • Learn the route around a plant and the target points for LDAR inspection, set up by a senior OGI technician.
  • Guide even the newest operator to follow the correct route and collect the right emissions data.
  • Captures images and data to prove emission and no-emission events.
  • Provides an audit trail that LDAR surveys were completed and accurate.
  • Helps customers meet 40CFR Part 60 – Appendix K requirements.
  • Quad-OOOOa certified MWIR sensor.
  • Camera built to meet the upcoming requirements of OOOOb and OOOOc.
  • AI-based ‘learning mode’ allows an experienced LDAR supervisor to perform the site survey once and then less experienced LDAR operators to accurately replicate the survey time after time.
  • Remote viewing tablet allows senior OGI technicians to train and certify newer OGI operators.

Definitions under Appendix K:

  • Ambient air temperature: The temperature of the air in the general location where the survey is conducted.
  • Applicable subpart: A section of environmental regulations (40 CFR part 60, 61, 63, or 65) that requires monitoring of regulated equipment for fugitive emissions or leaks and references the survey protocol.
  • Camera Configuration: Different settings and setups of a camera that impact its detection capabilities, such as operating mode, lens, portability, and viewer.
  • Delta temperature (delta-T or ∆T): The temperature difference between the emitted process gas and the surrounding background temperature. In practice, it's often assumed that the emitted process gas temperature equals the ambient air temperature.
  • Dwell time: The time needed to survey a manageable subsection of a scene to ensure effective leak detection. Dwell time starts when the scene is in focus and stable.
  • Fugitive emission or leak: Any emissions observed using technology.
  • Imaging: The process of creating a visual representation of emissions that might not be visible to the naked eye.
  • Operating envelope: The range of conditions (e.g., wind speed, delta-T, viewing distance) within which a survey must be conducted to achieve quality objectives.
  • Optical gas imaging camera: Hand-held, portable equipment that makes emissions visible that are otherwise invisible to the naked eye.
  • Persistent leak: A leak that is not intermittent in nature.
  • Repair: The act of adjusting or altering a component to eliminate a leak.
  • Response factor: The camera's response to a specific compound of interest compared to a reference compound at a concentration path-length of 10,000 parts per million-meter. These factors can be obtained from peer-reviewed articles or developed according to approved procedures.
  • Senior camera operator: An experienced camera operator who has conducted surveys at a minimum of 500 sites throughout their career, including at least 20 sites in the past 12 months, and has completed or developed the required camera operator training.
