Since many of the gasoline dispensing facilities regulated by Office of Air Resources have Underground Storage Tanks, they are also regulated by the Underground Storage Tank Management Program. Both programs work together in this field, however the owner/operator of a gasoline dispensing facility is responsible for knowing and complying with regulations and requirements of both programs.

For information, site-specific requirements, or other questions related to installation of spill containment basins, riser, or other modifications to the UST system, please call the main office at (401) 222-2797 or contact Clare O’Connor at (401) 222-2797 ext. 2777121 or

Program News & Updates

February 2021
New Stage I CARB Certified EVR Forms

  • Two new forms were created to further clarify and collect information regarding the Stage I CARB Certified system upgrades.
  • The Install or Modification Notification form is to collect information about the facility and the equipment chosen for Stage I CARB EVR upgrades before the installation or modification has occurred. This will help with the information shared between the Office of Air Resources and the Underground Storage Tank Management program or the Aboveground Storage Tank Management Program, as both offices need to be involved in the process.
  • The Install or Modification Certification – Post Construction is a form created to collect information after the install or modification of an approved project that has occurred. This is to ensure that proper procedures were followed, and testing had occurred.
  • To find the new Stage I CARB EVR forms please see below or check out the Forms & Applications section of the OAR website. See “Stage I Forms”.
  • If you have any questions on how to fill out the forms, please email
