. Summary of Proposed Action: The draft general permit is for a single source category, gasoline dispensing facilities (GDFs), and would be available in certain areas of Indian country that are within the geographical boundaries of California. This includes areas located in an Indian reservation or in another area of Indian country (as defined in 18 U.S.C. 1151) over which an Indian tribe, or the EPA, has demonstrated that the tribe has jurisdiction and where there is no EPA

- approved minor NSR program in place. The EPA is proposing this general

### ***Public Notice***

Page 2 of 2 permit as an option for CAA minor NSR preconstruction permit ting to help streamline the EPA’s permitting of certain minor sources that construct or modify in Indian country and belong to the GD F source category. The primary pollutant of concern for GDFs that may use this general permit is v olatile organic compounds (VOC) , which are emitted from storage tanks and gasoline dispensing units at GDFs . Some GDFs may also have emergency engines, but only those sources with emergency engines that are exempt from minor NSR permitting requirements may use this general permit. Emissions of all other regulated NSR pollutants from new or modified GDF sources that may use the general permit are expected to be below the minor NSR permitting thresholds in 40 CFR 49.153. This draft gener al permit regulates VOC emissions from GDFs , and includes emission limitations that require each GDF to control emissions fro m storage tanks during unloading of the gasolin e cargo from the tanker truck, using what are known as Stage I controls. In addition, the draft general permit requires GDFs in ozone nonattainment areas to limit VOC emissions resulting from vehicle refueling by recovering vapors displaced from the vehicle fuel tank, using pump

- based controls known as Stage II controls. There are also limits on the amount of gasoline each GDF can dispense in a 12

- month period: 25,000,000 million gallons in ozone attainment are as, and marginal and moderate ozone nonattainment areas; and 15,000,000 gallons in serious, severe, and extreme ozone nonattainment areas. The emission limitations in the draft general permit are expected to limit emissions of VOC from a new or modified GD F to less than 30 tons per year (tpy) in attainment areas and marginal and moderate ozone nonattainment areas and 8 tpy in serious, severe, and extreme ozone nonattainment areas. The detailed emission limitations are included in the draft permit and discus sed in detail in our Technical Support Document for this draft permit, and are available for review here: https://www.epa.gov/caa
