An owner/operator of a regulated petroleum storage tank facility is responsible for assessing and remediating a petroleum release upon discovery. Typically, a Recognized Environmental Professional is contracted to assist an owner/operator to respond to petroleum releases. OPS utilizes a formal method of risk evaluation based on the American Society of Testing and Materials Standard E 1739-95. This approach to risk evaluation allows for multiple closure criteria, or tiers, to be applied to a petroleum release.
OPS has the following remediation goals:
The release response section of the guidance addresses the topics of release discovery, initial abatement, characterization, corrective actions and closure criteria. OPS will issue a No Further Action letter once it has been demonstrated that the petroleum release is considered to be a low risk to human health and the environment. Petroleum release information will be archived in the OPS database and will indicate the appropriate closure criteria. A petroleum release investigation may be reopened if exposure conditions change.
You can contact the Remediation Section with questions by calling (303) 318-8547 or emailing us at firstname.lastname@example.org.
