What is E15?
The EPA defines E15 as a blend of gasoline that contains greater than 10% ethanol, and up to 15% ethanol. Under current Wisconsin law, E15 must be sold as an alternative fuel, and cannot be labeled as gasoline.
What steps are required to switch my current fuel dispensing system to sell E15?
All of the following steps must be taken:
- Storage tank plan approval is required. A DATCP certified installer must complete part I of the department’s TR-WM-132 Alternative Fuel Installation/Conversion Application Form and submit it to the department as part of the plan review submittal.
- Before commencing normal fueling operations using E15, the operator must notify the state inspector for their area to arrange for a pre-operational inspection. The operator must complete part II of the department’s TR-WM-132 Alternative Fuel Installation/Conversion Application Form and provide the completed form to the state inspector performing the pre-operational inspection.
- Tanks previously containing another type of fuel must be cleaned in accordance with API 2015 before introducing the ethanol-blended fuel. All cleaning work must be performed by a DATCP certified tank cleaner unless otherwise approved by the department based on an alternate cleaning method.
- A precision tightness test must be performed on the tank and piping before placing the tank system back into service.
- Equipment used for dispensing E15 must be listed or must be recognized by the manufacturer as being compatible with ethanol-blended fuel, except where otherwise approved in writing by the department.
