These states include: (see map)
Arizona, California, Florida, Illinois, Indiana, Kentucky, Michigan, New Jersey, New York, Ohio, Wisconsin, Wyoming, plus American Samoa, CNMI, and Guam. And all USTs in Indian Country.
New rules include:
No new ball float valves. Ball float valves can no longer be installed in new USTs and existing sites whose ball float valves fail must be replaced with either an automatic shut off device or high level alarm (or both as we recommend.)
Notifying the local UST agency when storing greater than B20 diesel and E10 Ethanol gasoline. If you store these fuels, and you haven’t already done so, you must notify your implementing agency.
Demonstrating UST system compatibility with alternative fuels. This might be a biggie. If you store alternative fuels you have to demonstrate to the implementing agency that the fuel won’t damage the UST system. You must demonstrate the tanks, piping, dispensers and all related equipment is compatible with these fuels. Check with your agency about how to meet this requirement but also follow this EPA link Ensuring Compatibility of Alternative Fuels with USTs and Converting Equipment to Store Alternative Fuels.
Requiring release detection on all new emergency power generator USTs. Some states like WA have required this for years but now emergency power generator tanks installed after this date must be set up to perform release detection.
Testing UST systems following any (newly defined) repair. In the past “repair” basically meant plugging a hole in a UST system that leaked. So you could have a bad sump penetration fitting that could lead to a leak but you won’t have to necessarily “repair” it. No more. Any part of the UST that, if failed and could lead to a release must be corrected and tested. Hopefully we’ll see fewer leaks because operators are being more proactive.
Notifying the UST agency within 30 days of a newly installed UST. Might be old news but if you install a new UST system you must notify the UST agency within 30 days.
Removing tanks with failed internal liners. Liners that fail the periodic test that cannot be repaired must be removed.
