STATE USE ONLY I.D. #_____________________ Date Received______________
INSTRUCTIONS (READ THIS FIRST)
Complete and return a UST-3 form at least thirty (30) days prior to closure or change-in-service activities.
Completed UST closure or change-in-service site assessment reports, along with a copy of the UST-2A and/or 2B forms, should be submitted
to the appropriate Division of Waste Management (DWM) Regional Office within thirty (30) days following closure activities. The UST-2 form
should also be submitted to the Central Office in Raleigh so that the status of the tanks may be changed to permanently closed and your
tank fee account can be closed out. Note: Tank fees may be due for unregistered tanks.
UST closure and change-in-service site assessments must be completed in accordance with the latest version of the Guidelines for Site
Checks, Tank Closure and Initial Response. The guidelines can be obtained at https://deq.nc.gov/about/divisions/waste-management/ust.
Note: To close tanks in place you must obtain prior approval from the DWM Regional office located in the region where the facility is located.
You must make sure that USTs removed from your property are disposed of properly. When choosing a closure contractor, ask where the
tank(s) will be taken for disposal. Usually, USTs are cleaned and cut up for scrap metal. This is dangerous work and must be performed
by a qualified company. Tanks disposed of illegally in fields or other dumpsites can leak petroleum products and sludge into the environment.
If your tanks are disposed of improperly, you could be held responsible for the cleanup of any environmental damage that occurs.
