Installer / Inspector / Company Certification
The Pennsylvania Storage Tank and Spill Prevention Act (Act 32 of 1989) and DEP regulations established a certification program for installers and inspectors of aboveground and underground storage tanks. Only DEP certified storage tank installers and/or inspectors may install, modify, remove or inspect storage tanks.
Tank Owners and Operators
Storage tank owners should verify which activities a person is certified to conduct before employing his or her services. For example, a person certified only to conduct an underground tank removal cannot perform a tank installation.
Owners and operators are encouraged to obtain bids from several contractors. Once an inspector or tank handler is chosen, obtain a written contract that describes the work to be performed and what will happen if unplanned events occur, such as discovery of additional tanks or contaminated soil, or compliance violations, etc.

DEP has established 14 different certification categories: four categories for USTs, nine categories for ASTs, and one tank lining category. Each category involves minimum levels of knowledge, experience and performance which must be demonstrated by individuals seeking certification. It is a violation of Act 32 for anyone to perform tank handling or inspection activities without certification in the proper category, unless they are working as an apprentice under the direct, on-site supervision of an appropriately certified individual. See Fact Sheet 1647,
