Gas stations

Wisconsin's Small Business Environmental Assistance Program (SBEAP) has a variety of tools and resources to help owners and operators of gasoline dispensing facilities understand the environmental regulations affecting their sector.

Compliance calendar

One of the SBEAP's most popular tools, the Compliance Calendar for Gasoline Dispensing Facilities is published every other year to provide you the most up-to-date information available. If you have any questions on the information below, or to request a hard copy of the calendar, see the contact information on the right side of the page.

Other environmental regulatory resources

Regular unleaded gasoline contains 10% ethanol, while E15 gasoline contains 15% ethanol. For more information on E15 fuel, refer to the Fuel Quality Fact Sheets on the Department of Agriculture, Trade and Consumer Protection's website. Other fuel-related requirements may be found on Vehicles - Mobile sources.

Air regulations

Waste regulations

Water regulations

  • If your station includes a car wash:
    • Car rinse or wash water, NOT going to a holding tank and/or sewer/treatment plant? You need coverage under the DNR's Low-Impact Discharge general permit or potentially an individual wastewater permit.
    • Complete the eligibility questionnaire to determine if coverage under the general permit is appropriate.
    • Review the fact sheet that summarizes the requirements in the permit.
    • Other materials, including links to the Notice of Intent form and Best Management Practice plan, are available on the General Permits webpage.
