On April 30, 2018, the U.S. Environmental Protection Agency (EPA) signed proposed amendments to the 2016 federal implementation plan (FIP) for managing air emissions from new and modified true minor oil and natural gas sources in Indian country. The FIP limits emissions of harmful air pollutants while providing streamlined construction authorization for new and modified “true minor sources” in the oil and natural gas production and natural gas processing segments of the oil and natural gas sector. The proposed amendments would allow the FIP to continue to apply in portions of the Uintah and Ouray Indian Reservation that may be included in an area EPA has designated as nonattainment for the 2015 national ambient air quality standards for ozone. The current FIP applies only in areas designated as attainment, attainment/unclassifiable or unclassifiable.
