“Quad O” refers to the Environmental Protection Agency’s (EPA) regulations for controlling emissions of volatile organic compounds (VOCs) from new, modified, and reconstructed oil and natural gas sources in the United States. The name “Quad O” comes from the codification of these regulations under Title 40 of the Code of Federal Regulations (CFR), Part 60, Subpart OOOO, or simply “Quad O.” These regulations aim to reduce harmful air pollutants emitted during the production, processing, transmission, and storage of oil and natural gas.

The significance of Quad O regulations lies in their impact on reducing emissions of volatile organic compounds (VOCs) and other air pollutants from oil and natural gas operations. VOCs are a type of air pollutant that can contribute to the formation of ground-level ozone and smog, which have adverse effects on human health and the environment.

By regulating emissions from various stages of oil and natural gas production, Quad O helps to mitigate these harmful effects. It sets specific emission standards for equipment such as storage tanks, compressors, and pneumatic devices, as well as requirements for leak detection and repair programs. Compliance with Quad O regulations ensures that oil and gas operations minimize their environmental impact and contribute to cleaner air quality.

Additionally, Quad O regulations play a role in addressing climate change, as VOCs are also considered greenhouse gases that contribute to global warming. By reducing VOC emissions, Quad O indirectly helps to mitigate climate change impacts associated with the oil and gas industry.
