Oklahoma Administrative Code › Title 165 - Corporation Commission › Chapter 29 - Corrective Action of Petroleum Storage Tank Releases › Subchapter 3 - Release Prevention, Detection and Correction › Part 1 - RELEASE PROHIBITION, REPORTING, AND INVESTIGATION › Section 165:29-3-2 - Release reporting

Current through Vol. 41, No. 20, July 1, 2024
(a)
				  These reporting requirements do not relieve the owner or operator of the
				  responsibility to take corrective action as required by this Subchapter to
				  protect human health and the environment, including the containment and cleanup
				  of spills and overfills that are not required to be reported.
(b) All petroleum storage tank system owners,
				  operators, their agents and employees, or transporters must report to PSTD
				  within twenty-four (24) hours of discovering any substances, conditions or
				  monitoring results that indicate a release may have occurred using the link
				  provided on the release reporting tab located on PSTD's webpage on the
				  Commission website; by email at PSTReleaseReporting@occ.ok.gov; or by telephone
				  at (405) 521-4683 or 1-888-621-5878. If after hours, or on weekends or
				  holidays, call the PSTD emergency phone number at (405) 823-0994. Owners or
				  operators must send written confirmation within twenty (20) days in accordance
				  with the release investigation and confirmation requirements of this
				  Subchapter. Events indicating a release include, but are not limited to, the
				  following:
(1) The discovery of released
				  regulated substances at the petroleum storage tank system facility or in the
				  surrounding area including, but not limited to, the presence of free product or
				  vapors in soils, basements, crawlspaces, sewer and utility lines, and nearby
				  surface water whether on-site or off-site.
(2) Any unusual operating conditions observed
				  by the owner or operator, like the unexplained erratic behavior of product
				  dispensing equipment, the sudden loss of product from the petroleum storage
				  tank system, an unexplained presence of water in the tank, or liquid in the
				  interstitial space of secondarily contained systems, unless the system
				  equipment or component is found not to be releasing regulated substances to the
				  environment; any defective system equipment or component is immediately
				  repaired or replaced; for secondarily contained systems, any liquid in the
				  interstitial space not used as part of the interstitial monitoring method (for
				  example brine filled) is immediately removed.
(A) In the case of inventory control, two (2)
				  consecutive thirty (30) day periods where the Total Gallons Over/Short is
				  greater than the "Leak Check" (one percent (1%) of product sales plus 130
				  gallons) must be reported to PSTD within twenty-four (24) hours of the
				  owner/operator discovering the inventory control results.
(B) Any UST system failure from a third
				  party-certified Statistical Inventory Reconciliation (SIR) analysis must be
				  reported to PSTD by the owner, operator, or SIR provider within twenty-four
				  (24) hours of discovering the failure. An immediate investigation into the
				  cause of the failed report must be conducted and results reported to PSTD
				  within seven (7) days.
(C) An
				  "Inconclusive" report from an SIR analysis must be reported by the SIR
				  provider, owner or operator within twenty-four (24) hours of report generation.
				  An Inconclusive means that the UST system has failed to meet leak detection
				  requirements for that thirty (30) day period.
(3) An unusual level of vapor on the site
				  that is of unknown origin. A vapor monitor well reading in excess of 4,000
				  units/ppm, or 1,500 units/ppm for diesel storage tanks, must be reported to
				  PSTD within twenty-four (24) hours by the owner, operator, their agents, or
				  employees discovering the monitoring results. If diesel and gasoline tanks
				  share the same tankpit, the reporting level is 1,500 units/ppm. Within ten (10)
				  days, the owner or operator must submit to PSTD all vapor monitoring well data,
				  including background data, for the last twelve (12) thirty (30) day periods.
				  Upon examination of the submitted data, PSTD will advise the owner or operator
				  what action, if any, he or she needs to take. Whenever these vapor thresholds
				  are exceeded the tank owner must provide alternative test results that confirm
				  the petroleum storage tank system is currently not leaking.
(4) An increase in vapor levels of 500
				  units/ppm above background or historical levels detected by thirty (30) day
				  monitoring, even though below the twenty-four (24)-hour reporting level, must
				  be reported if the increase does not correct itself in the second thirty (30)
				  day period of monitoring and it must be reported to PSTD within twenty-four
				  (24) hours of the owner, operator, their employees, or agents discovering the
				  monitoring results.
