​Storage Tank Release and Cleanup Locations

DEP is committed to providing information in an accessible and user-friendly format. In order to do so more effectively, DEP has created interactive reports that allow the user to select specific criteria for the desired information. The storage tank cleanup locations are available here:

This report represents confirmed release incidents that have been reported to DEP since enactment of the Storage Tank and Spill Prevention Act (Tank Act) in July, 1989. These release incidents represent leaks, spills and overfills which have occurred from storage tank systems regulated by the Tank Act only. Releases from home heating oil tanks, which are not regulated by the Tank Act, are not part of this list. The purpose of this list is to provide information on the cleanup status of all known release incidents which have occurred from regulated storage tank systems in Pennsylvania. The information in these Interactive Reports are derived from DEP's eFACTS (Environment, Facility, Application, Compliance Tracking System).

For information pertaining to a specific release incident, please contact the Environmental Cleanup Program in the appropriate DEP regional office. General questions pertaining to this list can be directed to ra-eptankcleanup@pa.gov

MUNICIPALITY - The name of the primary municipality in which the storage tank facility is located.

FACILITY ID - The unique, system-generated identification number assigned to the storage tank facility. This is the eFACTS Facility ID.

PROGRAM OTHER ID - The site-specific identification code assigned to the storage tank facility by DEP's storage tank program.  This is the Storage Tank Facility ID.

FACILITY NAME - The name of the storage tank facility.

ADDRESS1 - The location address of the storage tank facility.

ADDRESS2 - The location address of the storage tank facility continued.

CITY - The postal address city in which the storage tank facility is located.

ZIP - The zip code in which the tank facility is located.

LATITUDE, LONGITUDE - The location of the tank facility using degree decimal coordinates if known and recorded in eFACTS. If blank, no information is recorded in eFACTS.

HORIZONTAL REFERENCE DATUM, ALTITUDE DATUM - The reference datum that is used to project the Lat/Long datum onto a map. If blank, no information is recorded in eFACTS.

CLIENT ID - The unique, system-generated identification number assigned to the DEP client record for the owner of the storage tank facility.

CLIENT / OWNER – The name of the owner of the storage tank facility.

INCIDENT ID - The unique, system-generated identification number assigned to the tank release incident.


SUSPECT DATE - The date DEP suspects the release occurred.

CONFIRMED DATE - The date the release was known to have occurred or was discovered. Where the date is unknown, the default date is the effective date of the Tank Act (Aug. 5, 1989).

STATUS CODE - The current cleanup status of the incident. The codes (numbers 1 through 9) and their descriptions are as follows:

  1. Interim Remedial Actions Not Initiated - No physical activity to remove contaminants has been initiated.
  2. Interim or Remedial Actions Initiated - At a confirmed release, site characterization and/or physical activity to remove contaminants are underway.
  3. Attainment Monitoring in Progress - Demonstration of an Act 2 groundwater standard is being conducted.
  4. Cleanup Completed - It has been demonstrated to DEP that contaminants were removed to applicable cleanup standards, or that the release was completely contained and recovered and no environmental impact occurred.
  5. Inactive - Incidents in this status have not achieved 'cleanup completed' status. However, these incidents have been determined by DEP to be low priority for corrective action as a result of meeting the following criteria:
    • No product in the leaking storage tank system
    • No known free product in the environment
    • Risks to human health and the environment have been mitigated including vapor/fire/explosion hazards, contaminated drinking water supplies, and releases to surface waters
    • Strong potential for receptors to be impacted is not known to exist
    • Responsible party is not performing or planning to perform corrective action
    • The case is at least two years old
  6. Suspected Release - Investigation Pending or Initiated
  7. Suspected Release - Investigation Complete, No Release Confirmed
  8. Administrative Close Out (ACO) - A facility where multiple releases have occurred that are being remediated together through ongoing corrective action. This corrective action will be tracked for the primary release incident, and the other release incidents will be assigned the ACO status. The ACO status is also assigned to release incidents that are being remediated through DEP’s Land Recycling Program (Act 2) cleanup process.
  9. Unverified Incident – Release incidents that were entered into DEP’s database but are not supported by any written records or institutional knowledge of the incident.
