COMPLIANCE QUAD OTECQ EPA Oil and gas production processes result in the venting of a portion of the produced natural gas. Vent gas management is a continuing issue for oil and gas operators. Companies must balance permitting requirements, regulatory compliance and corporate responsibility to minimize pollution, waste and liabilities. Recovery of the vent gas increases revenue to the facility while releasing the gas to the atmosphere or combusting the gas results in air pollution. This makes an understanding of vent gas and a practical management strategy important. Certain oil and gas production facilities with applicable requirements in 40 CFR 60 Subpart OOOO and OOOOa are required to submit an annual report to the USEPA and state environmental agency (if the state has delegation). Most states have EPA delegation to administer these two rules.

A Few Reasons 1. Complying with regulations can make your company money. Vapor recovery unit compressors (VRU)can be used for storage tank methane recovery and VOC recovery for injection into the sales pipeline. Using a leak detection and repair program (e. g. leaking thief hatches) can help send more product to sales. 2. Fines up to $37, 500 per day per violation with a maximum of $320, 000 possible for failure to comply. See Federal Register Notice from November 26, 2013. 3. Non-compliance could result in shut-in of production. 4. The cost of defense/response (e. g. , attorneys, staff, and travel costs) associated with noncompliance often exceed the cost of the fine.

5. Public opinion, especially social media and internet news stories, can taint the perception of all oil and gas operators and can fuel much more regulation. Example: oil spills, flaring of associated gas in shale plays. 6. Compliance helps reduce environmental liabilities that have to be disclosed to shareholder groups, SEC, investors. This could affect the value of the company’s stock. 7. Compliance reduces methane emissions. Methane is a regulated greenhouse gas emission that has a global warming potential of 25. Reducing 1000 tons of methane is the same as reducing 10, 000 tons of CO 2 emissions. 8. A history of environmental non-compliance could limit the ability of a company to obtain permits to operate facilities – nationwide. Some states use noncompliance history (serial offenders) as criteria for granting/rejecting approval of air permits. Many state regulatory agencies (such as TECQ) assign scores or ratings based on a facility or operator’s compliance history.
