1. (a) Every owner or operator of a petroleum storage tank system must, in response to a confirmed release from a petroleum storage tank system, comply with the requirements of this Part, with the exception of those systems excluded from regulation in OAC 165:25 and 165:26.
2. (b) All work associated with the assessment, characterization, investigation, remedial action, and closure from a release or suspected release of a regulated substance should be pre-approved by PSTD.

3. (c) Upon confirmation of a release, or after a release from the petroleum storage tank system is identified, the owner or operator must perform the following initial response actions:

   1. (1) Report the release to PSTD 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; by telephone at 405-521-4683 or 1-888-621-5878. If after hours, or on weekends or holidays call the PSTD emergency number at 405-823-0994.
   2. (2) Take immediate action to prevent any further release of the regulated substance into the environment, and prove that any system still containing fuel is tight by having a system tightness test performed.
   3. (3) Identify and mitigate any fire, explosion, and vapor hazards.
   4. (4) Remove free product to the extent practicable as determined by PSTD while continuing, as necessary, any actions required by this Subchapter.
4. (d) Any corrective action work performed at a release site must have prior documented verbal or written approval by a member of PSTD staff to be considered reimbursable by the Indemnity Fund. This requirement for pre-approval excludes required emergency spill mitigation measures. Additionally, field work associated with all corrective actions requires 48-hour (two working days excluding holidays and weekends) written notice to PSTD of scheduled field activities. Notice must be made to the PSTD staff member assigned to the case, his/her Supervisor and the PSTD Technical Manager.
