Effective January 1, 2016, an amendment to the Aboveground Petroleum Storage Act (APSA) has updated the requirements for facilities with the potential to store more than 1,320 gallons of petroleum products on site.  Among the most significant changes is the clarified definition for "tanks in underground areas," generally defined as storage tanks located in a structure at least 10 percent below the ground surface.  The APSA is intended to supplement regulations regarding Spill Prevention, Control, and Countermeasure (SPCC) plans as required under 40CFR 112.  The complete bill can be found at here, and a guidance document summarizing these changes can be found here.

In addition to the current changes, the amendment requires aboveground storage tanks to comply with additional regulations set forth by the Office of the State Fire Marshal (OSFM).  It is anticipated that the OSFM will amend their regulations on 1/1/2018.
