Underground Storage Tanks | Draft Programmatic Environmental Assessment | Comment Period Closes June 4, 2024

  • May 06 2024

DEQ's UST section has prepared a Draft Programmatic Environmental Assessment (EA) for the installation of regulated USTs at new facility locations and is accepting public comment during the next 30 days. The type of comments DEQ is seeking would highlight any missed analysis in the Programmatic EA or issues related to the potential impacts from an Underground Storage Tank during construction or operation.

Historically, the UST program has prepared individual EAs for each new proposed facility. The Programmatic EA will replace individual EAs for applicable new proposed facility locations.

When the programmatic EA is finalized, owners or operators proposing tank installations at new facilities will fill out an application, and DEQ will determine if the project falls within the bounds of the Programmatic EA using a Categorical Exclusion. If it does, the Categorical Exclusion and the application will be put out for public comment for 10 working days. DEQ will then consider public input and make a final permitting decision.

The Final Programmatic EA would include responses to public comments and how DEQ made any changes based on the public comments to the document.
