The Pennsylvania DEP regulates both aboveground and underground storage tanks that contain regulated substances, including petroleum products. While there are some exceptions for tanks based on size or use, most tanks are subject to DEP regulations. These tanks can only be installed, modified, or inspected by companies with the proper certification. There are requirements for technical specifications, work practices, registration, recordkeeping, inspections and more.
The EPA also has storage tank regulations and requirements for Spill Prevention, Control, and Countermeasure (SPCC) Plans.
