UST Regulatory Compliance & EPA Standards

Question 1

Which federal agency is primarily responsible for regulating underground storage tanks (USTs)?

Accepted Answer

EPA

Answer

The U.S. Environmental Protection Agency (EPA) is the federal agency primarily responsible for regulating underground storage tanks (USTs). Under Subtitle I of the Resource Conservation and Recovery Act (RCRA), the EPA sets national standards to prevent, detect, and clean up releases from USTs. These regulations aim to protect groundwater and soil from contamination by hazardous substances.

Question 2

What is the minimum capacity of a tank that qualifies it as a regulated UST under EPA rules?

Accepted Answer

More than 110 gallons

Answer

Under EPA regulations (40 CFR Part 280), a tank is generally considered a regulated UST if it has a capacity of more than 110 gallons. This threshold helps focus regulatory efforts on tanks that pose a significant environmental risk due to the volume of hazardous substances they can contain. Tanks smaller than this capacity are typically exempt from federal UST regulations.

Question 3

What must UST owners do if a release is suspected or confirmed?

Accepted Answer

Notify the state agency and begin investigation

Answer

If a release from a UST is suspected or confirmed, owners and operators are legally required to immediately notify the state implementing agency. Following notification, they must begin an investigation to determine the source and extent of the release. Prompt action is crucial to prevent widespread environmental contamination and mitigate potential hazards.

Question 4

What documentation must be kept to demonstrate compliance with UST regulations?

Accepted Answer

Written inspection and maintenance records

Answer

To demonstrate compliance with UST regulations, owners and operators must maintain comprehensive written records. These records include documentation of inspections, maintenance activities, release detection results, and financial assurance. Such documentation allows regulatory agencies to verify that the UST system is being properly managed and monitored according to federal and state requirements.

Question 5

How often must a walkthrough inspection be conducted on UST systems according to EPA rules?

Accepted Answer

Monthly

Answer

According to EPA rules (40 CFR Part 280.36), UST owners and operators must conduct walkthrough inspections on their UST systems monthly. These regular inspections ensure that release detection equipment is functioning, spill prevention equipment is clean, and all components are in good operating condition. Monthly checks help identify potential issues before they escalate into significant problems.
