Subchapter D. CORRECTIVE ACTION PROCESS FOR
OWNERS AND OPERATORS OF STORAGE TANKS AND
STORAGE TANK FACILITIES AND OTHER
RESPONSIBLE PARTIES

 (a)  For a corrective action required by this subchapter, the Department may do one or more of the following:

   (1)  Direct or order the responsible party to perform the corrective action.

   (2)  Perform the corrective action.

   (3)  Direct that the corrective action be performed by a third party.

   (4)  Seek other appropriate administrative or court ordered relief.

 (b)  For a corrective action required by this subchapter, the Department may collect or recover, from the responsible party, the Department’s costs and expenses involved in taking corrective action in accordance with this subchapter, authorizing a third party to take corrective action under this subchapter and initiating cost recovery actions under this subchapter. The Department may collect the amount in the same manner as civil penalties are collected under section 1307(b) of the act (35 P. S. §  6021.1307(b)).

 (c)  For corrective actions required by this subchapter, it will be presumed as a rebuttable presumption of law in civil and administrative proceedings that a person who owns or operates an aboveground or underground storage tank is liable, without proof of fault, negligence or causation, for damage, contamination or pollution within 2,500 feet of the perimeter of the site of a storage tank containing or which contained a regulated substance of the type which caused the damage, contamination or pollution. The presumption may be overcome by clear and convincing evidence that the person so charged did not contribute to the damage, contamination or pollution.

 (d)  To overcome the presumption of liability established in subsection (c), the owner or operator shall affirmatively prove, by clear and convincing evidence, one of the following:

   (1)  The damage, contamination or pollution existed prior to the use of a storage tank at the facility to contain an accumulation of regulated substances, as determined by surveys of the site and within 2,500 feet of the perimeter of the storage tank or facility.

   (2)  An adjacent landowner refused to allow the owner or operator of a storage tank at a new facility access to property within 2,500 feet of the perimeter of a storage tank facility to conduct a survey.

   (3)  The damage, contamination or pollution was not within 2,500 feet of the perimeter of a storage tank.

   (4)  The owner or operator did not contribute to the damage, contamination or pollution.

 (e)  The Department may waive or combine one or more of the requirements of this subchapter based on:

   (1)  The nature, extent, type, volume or complexity of the release.

   (2)  The general characteristics of the site and the regulated substances which were released.

   (3)  The corrective action which occurred subsequent to the release.

 (f)  The Department’s acceptance or approval of an interim remedial action, site characterization, site characterization report, remedial action plan, remedial action or remedial action completion report, does not constitute and may not be construed as a release from civil or criminal liability in an administrative, civil or criminal proceeding.

 (a)  The owner or operator of storage tanks and storage tank facilities shall initiate and complete an investigation of an indication of a release of a regulated substance as soon as practicable, but no later than 7 days after the indication of a release.

   (1)  The presence of a regulated substance or an unusual level of vapors from a regulated substance of unknown origin, at a storage tank facility.

   (2)  Evidence of a regulated substance or vapors in soils, basements, sewer lines, utility lines, surface water or groundwater in the surrounding area.

   (3)  Unusual operating conditions, indicative of a release, such as the erratic behavior of product dispensing equipment.

   (4)  The sudden or unexpected loss of a regulated substance from a storage tank, or the unexplained presence of water in a storage tank.

   (5)  Test, sampling or monitoring results from a release detection method which indicate a release.

   (6)  The discovery of holes in a storage tank during activities such as inspection, repair or removal from service.

   (7)  Other events, conditions or results which may indicate a release.

 (b)  The investigation required by subsection (a) shall include a sufficient number of the procedures outlined in this subsection and be sufficiently detailed to confirm whether a release of a regulated substance has occurred. The owner or operator shall investigate the indication of a release by one or more of the following procedures:

   (1)  A check of product dispensing or other similar equipment.

   (2)  A check of release detection monitoring devices.

   (3)  A check of inventory records to detect discrepancies.

   (4)  A visual inspection of the storage tank or the area immediately surrounding the storage tank.

   (5)  Testing of the storage tank for tightness or structural soundness.

   (6)  Sampling and analysis of soil or groundwater.

   (7)  Other investigation procedures which may be necessary to determine whether a release of a regulated substance has occurred.

 (c)  If the investigation confirms that a reportable release has occurred, the owner or operator shall report the release in accordance with §  245.305 (relating to reporting releases) and initiate corrective action.

 (d)  If the investigation confirms that a nonreportable release has occurred, the owner or operator shall take necessary corrective actions to completely recover or remove the regulated substance which was released.

 (e)  If the investigation confirms that a release has not occurred, further investigation by the owner or operator is not required.
