One Year Extension of the 2019 Tank Removal Incentive

The Petroleum Storage Tank Committee approved an extension of the 2019 Tank Removal Incentive to December 31, 2020. View the new 2020 Tank Removal Incentive!

Two-year Timeframe to Submit Costs for Reimbursement Beginning 1/1/2020

All Applicants to the Petroleum Reimbursement Fund: Effective January 1, 2020, all costs incurred related to assessment and cleanup of petroleum contamination must be submitted within two years of when they were incurred per Petroleum Storage Tank Committee Policy 26. 

Please ensure that you stay current with your requests for reimbursement. Costs incurred more than two years prior will not be accepted for reimbursement.

Spill Bucket Repair/Replacement Following a Failed Test

As underground storage tank (UST) owners test their spill buckets in advance of the January 1, 2020 deadline, OPS is becoming aware of challenges with contractor scheduling and equipment supplies.  As a result, OPS is allowing up to 15 days following a failed spill bucket test for a tank owner to complete the necessary spill bucket repair or replacement.  If repairs cannot be made after 15 days, either by chemical or mechanical means, delivery prohibition will be invoked.  Additionally, OPS reserves the right to apply delivery prohibition in, particularly high-risk situations.

If a spill bucket fails an integrity test by visual inspection, hydro test, or vacuum test, the tank owner must do the following:

1. Report the failed spill bucket test as a confirmed release to the OPS Technical Assistance Line at 303-318-8547 within 24 hours.
2. Review the Spill Prevention Equipment Repair Guidance and schedule spill bucket repair or replacement as soon as possible in order to avoid potential environmental contamination and delivery prohibition.  
3. Schedule an environmental site assessment to fulfil the requirements of the request from OPS for a Site Characterization Report.  Consider that assessment directly under the spill bucket is only possible if the bucket is going to be replaced.
4. Notify OPS of the results of the repair/replacement and followup integrity test results using the Minor Equipment Repair Form.

Approved RCG Changes Effective July 1, 2019

The Petroleum Storage Tank Committee (PSTC) approved changes to the Reasonable Cost Guidelines (RCG's) that were proposed by OPS staff at the May 17, 2019 PSTC meeting. Subsequently, OPS received feedback from the REP Peer Group regarding the continuous soil sampling requirement included for drilling Task and Labor Code 2.1.

As pointed out by the REP Peer Group, the continuous soil sampling requirement was not included in the previous RCG proposal presented at the March 15, 2019 PSTC meeting. Therefore, the opportunity for stakeholder comment was not provided regarding the continuous soil sampling requirement. In addition, there are instances where continuous soil sampling is not technically feasible or necessary (e.g., bedrock lithology; deep water table; distal POC wells). As a result, the continuous soil sampling requirement has been removed from Task and Labor Code 2.1, and Task and Labor Code 2.99 has been restored to utilize as needed for continuous soil sampling costs.

However, as also pointed out by the REP Peer Group and specified in the Site Characterization Soil Sampling section of the OPS Petroleum Guidance, soil borings and monitoring wells in source areas should be continuously sampled when technically feasible. Employing 5-foot soil sample intervals is discouraged when defining the extent and distribution of contamination in source areas because it will create data gaps by design. The success of a corrective action plan is dependent on an effective site characterization, which includes delineating source areas, characterizing heterogeneity (high flux vs. mass storage zones), and identifying targeted treatment areas requiring remediation.

The 2019 RCG changes will be reflected in Version 2.1 of the Corrective Action Plan Report, effective July 1, 2019.

SPA Approval for UST Regulations

CDLE-OPS received final State Program Approval (SPA) from the U.S.Environmental Protection Agency (EPA) on July 19, 2019, for the Underground Storage Tank (UST) Program. CDLE-OPS submitted a complete program revision application to EPA on July 6, 2018, seeking EPA approval of Colorado's revisions corresponding to the EPA final rule published on July 15, 2015. The final approval of CDLE-OPS' UST revisions and codification can be viewed on the Federal Register.

2019 Incentive Program

The Petroleum Storage Tank Committee approved an incentive for 2019 effective March 17, 2019. View the document for more details about how to apply.

New Temporary Closure Forms Available

We updated our Temporary Closure forms for USTs/ASTs and created a new Request for Temporary Closure Extension form.

Please take a moment to retrieve and review these forms on our Tank Compliance page. 

Please use the new Notice of Intent to Place Tanks into Temporary Closure forms for both Aboveground and Underground tanks going forward, as well as the Temporary Closure Extension Request form when appropriate. Please discontinue the use of the older forms as they may be returned.

Policy 29 Approved

The Petroleum Storage Tank Committee voted to adopt Policy 29, effective March 18, 2019. 

Updated Petroleum Guidance for Suspected Releases

The revised Petroleum Storage Tank Regulations became effective March 17, 2019, and they include changes to Article 4 for suspected release identification, reporting, and response to better align OPS regulations with EPA regulations.

To aid tank owners/operators in complying with these regulation changes, the Release Discovery and Reporting section of the online Petroleum Guidance will be revised with an updated Release Reporting Process Diagram and an updated diagram of Examples of Suspected Releases.
