Do the NJDEP Underground Storage Tank Regulations Apply to You?


An industrial facility with an Underground Storage Tank (UST) can be subject to the New Jersey Department of Environmental Protection’s (NJDEP) Underground Storage Tank regulations set forth at N.J.A.C. 7:14B.

By definition a UST is any one or combination of tanks as set forth in N.J.A.C. 7:14B-1.4, including appurtenant pipes, lines, fixtures, and other related equipment, used to contain an accumulation of hazardous substances, the volume of which, including the volume of the appurtenant pipes, lines, fixtures, and other related equipment, is 10 percent or more beneath the surface of the ground.

Unless one of the exemptions within N.J.A.C. 7:14B-1.4 applies, any facility that operates an UST must comply with the regulations as set forth in the chapter. For the full list of exemptions, refer to the N.J.A.C. citation; however, below are some of the more common exemption triggers for our manufacturing, pharmaceutical, and similar clients in New Jersey:
