DHEC only requires permits for new installations.
In order to build a new gas station or install a new tank at an existing facility, tank owners must start the permitting process. The first step in this process is to accurately fill out and submit the Application for a Permit to Install (pdf).
Points to consider
The review process for this application usually takes less than a week. Facilities located in one of the eight coastal counties will also have to gain approval from the Office of Ocean and Coastal Resource Management (OCRM), which could add some time to the application process. Once the review is complete and all required information is submitted, a Permit to Install will be issued to the tank owner. Once this permit is received, installation may begin.
Installation procedures must meet manufacturer requirements as well as industry standards (Note: The following industry codes and standards may be used).
Once installation has begun, DHEC will perform Phase inspections to monitor progress. Inspections must be scheduled at least 48 hours in advance to allow time for a DHEC representative to be present. The Phase 1 inspection will occur during installation of the tank(s). The Phase 2 inspection will occur during installation of the piping runs. The Phase 3 inspection will occur once spill prevention and overfill prevention equipment have been installed. Phase 2 and Phase 3 inspections may take place at the same time depending on when installation occurs.
If ballasting is required to anchor the tanks and fuel is used, written notification must be submitted to DHEC prior to the first fuel drop. Once the notification is received, an invoice will be issued for the current registration fees. Also, once fuel ballasting occurs, release detection must be conducted. Records of release detection must be made available for review during the Phase 2 piping inspection as well as submitted with the application.
An “As-Built” map is required to be submitted with the Application for a Permit to Operate (pdf). The map (which is not to exceed 8 ½” by 17”) should show site buildings, dispenser islands, canopy footings, USTs, product piping, and vent piping. The map must be accurate to within one foot. If it is available, the inspector will also verify the map during a Phase 2 or Phase 3 inspection.
Once all installation and testing per equipment manufacturer specifications has occurred, the tank owner may submit an Application for a Permit to Operate (pdf) for review.
A Permit to Operate will NOT be issued until the financial responsibility requirement is met.
