What Are The Responsibilities Of An UST Owner Or Operator?
In 2015, EPA revised the underground storage tank (UST) regulations. Below you will find the requirements for owners and operators.
All federally regulated USTs must:
- Be registered with the appropriate regulatory authority,
- Meet leak detection requirements, and
- Meet spill, overfill, and corrosion protection requirements.
In addition owners and operators must:
- Meet financial responsibility requirements,
- Perform a site check and corrective action in response to leaks, spills and overfills,
- Follow regulatory rules during installation of new tanks and closure of existing tanks,
- Maintain records as required, and
- Have periodic checks performed on corrosion protection and leak detection systems.
Beginning on October 13, 2015 owners and operators must:
- Notify the implementing agency within 30 days of an UST system ownership change;
- Notify the implementing agency at least 30 days before switching to a regulated substance containing greater than 10 percent ethanol, greater than 20 percent biodiesel, or any other regulated substance identified by the implementing agency and maintain records demonstrating the UST system meets the compatibility requirements; and
- Test or inspect following repairs to spill prevention equipment, overfill devices, and secondary containment areas.
Beginning on April 11, 2016 owners and operators must:
- Use secondarily contained tanks and piping when installing or replacing these components; and
- Use under-dispenser containment when installing new dispenser systems.
Beginning on October 13, 2018 owners and operators must:
- Have trained class A, class B, and class C operators,
- Perform periodic testing of spill prevention equipment and containment sumps used for interstitial monitoring of piping,
- Perform periodic testing of release detection equipment,
- Perform periodic inspections of overfill equipment,
- Perform periodic walkthrough inspections at the UST facility, and
- Perform release detection for emergency generator tanks.
Owners and operators of field-constructed tanks and airport hydrant systems previously deferred in the UST regulation must begin meeting the requirements in Subpart K.
UST owners and operators need to contact their state or local agency that implements the UST program to receive specific information on requirements for their tanks. If the tanks are located in Indian Country, then you should contact the EPA Regional Office.
EPA's regulations concerning USTs are contained in 40 CFR Part 280, 40 CFR Part 281 and 40 CFR Parts 282.50-282.105. The regulations are divided into three sections: technical requirements, financial responsibility requirements, and state program approval objectives.
