The lists above have been updated since licenses expired. There are some professionals who did not renew their license. Until they renew their licenses the Petroleum Storage Tank Division is unable to process any reports and/or purchase orders for work performed or anticipated after 12/31/2015. Not being licensed will also prevent individuals from performing installations, removals and well monitoring. If you need assistance renewing your license, please contact Cara Parent at (405) 522-2529.
