Emergency Power Generator UST Systems – 2015 Requirement for Release Detection
In 2015, EPA revised the underground storage tank (UST) regulations.
The 1988 UST regulation required UST systems that store fuel solely for use by emergency power generators to meet all of the regulatory requirements except subpart D – the release detection requirements. The revised UST regulation requires owners and operators of emergency power generator UST systems to meet the release detection requirements in subpart D as follows:
- Emergency generator UST systems installed on or before October 13, 2015 must begin meeting the release detection requirements not later than October 13, 2018.
- Emergency generator UST systems installed after October 13, 2015 must meet release detection requirements when they are installed.
