DEP Compliances

Our DEP Certified staff has over 75 years of combined experience in testing, inspections, and overall, DEP regulatory compliance.


We have a team of DEP Certified technicians to conduct your required annual testing (Annual Preventative Maintenance). Testing is site specific which may include sensor functionality, ATG certification, line and leak detector testing, and/or electronic line leak detector testing. Our technicians perform overfill protection testing and sump integrity testing and cathodic protection, if applicable. Our technicians take into consideration your desire to be in business as much as possible, so we try to minimize your downtime and respect the flow of customers through your location.


We have a team of DEP Certified inspectors to conduct your DEP Facility Operations Inspection. Most inspections are required every three years. Between those time periods, every facility is required to maintain their equipment, complete monthly walkthroughs to monitor for leaks from tanks and piping, keep required records of testing and leak detection monitoring, also keep a current registration for their facility. These are some of what the inspector is looking at when they come to your facility. They will inspect the material of construction for tanks and piping, type of leak detection used and the monitoring records to go along with it. They will also update you on what equipment or procedures you are currently using, and what might be outdated or becoming outdated.


PPSCO recommends Annual Preventative Maintenance plans for customers to help make sure they are compliant and up-to-date prior to their inspections, and help make the process go smoothly and quickly. No facility wants to receive a NOV (Notice of Violation) from the Department of Environmental Protection.


Site clean ups - leaking tanks/piping

There are many reasons that petroleum tank systems need to be removed or might have leaks that need to be cleaned up. From general tank removals because of age, leaking piping because of bad fitting or worn out materials, dispenser leaks, and tank overfills. These are some of the reasons that petroleum contamination might need to be dealt with at an owners location. Now, more and more we find leaks because our testing methodology is better and more precise. As older tanks (about 30 years old) are replaced we find that the material of construction might not have lasted as long as the manufacturer/owner had hoped. In some cases the leak ome from the inside out and sometimes outside in. It all depends on the material of construction and the design of the installation.

When we find a site that needs a cleanup or remediation performed it can be lengthy and costly process. That;s where our years of experience and network of environmental contractors come into play. We want you site to be cleaned up in the most efficient manner possible while still protecting the environment.
