Monthly Inspection

At EPS, we provide comprehensive monthly inspection and maintenance services for both underground (UST) and aboveground storage tanks (AST) in full compliance with state DEP regulations. Our team conducts thorough 30-day inspections to ensure your commercial tanks and pumps are functioning safely and efficiently. We monitor for leaks using approved methods such as ATG and interstitial monitoring, inspect piping, spill buckets, and containment sumps, and visually assess ASTs for corrosion, structural issues, or discharge. All findings are carefully documented, and any issues are addressed promptly to maintain compliance and avoid costly downtime or environmental risks. With our proactive approach, you can count on peace of mind and uninterrupted operations. We can work with you to make sure that your fuel storage is safe, environmentally secure and hassle free. 

Line tightness testing is a critical procedure required to verify that product piping—especially in underground storage tank systems—is free of leaks and pressure loss. This test is typically conducted annually or when required by regulation, using approved methods that detect leaks with a high degree of accuracy. It ensures compliance with state DEP standards and helps prevent environmental contamination or costly product loss.

We check the leak detector by simulating the prescribed leak rate and verifying its functionality.

Failure to service units correctly can lead to financial inefficiencies, operational issues, safety complications or environmental emission problems.
