What steps should I take to obtain a UST Plan Check Permit?

Obtain and complete the appropriate HMD application form(s). You may also pick up the forms in person at our office, or call the UST plan check desk and forms will be mailed to you.

Be sure to:

  • Obtain other permits, as needed, from the local fire department, Air Pollution Control District (APCD), and local building/planning department, if applicable.
  • Obtain and/or include a Board of Equalization (BOE) number.
  • Obtain and/or include an Assessors Parcel number.
  • Prepare plan drawings (submit the original and two copies).

PLEASE NOTE: Tank removals do not require a permit from the APCD or a BOE number, but do require that you complete a UST Closure Work-Plan (to be completed by the contractor) and a Post Tank Removal Work-Plan if question 4 of the application is marked "yes". 

How long will it take to get my permit reviewed?

Provided that all the required documents have been properly completed and that all applicable fees have been paid, most plans are reviewed within 7-10 working days. The plan check technician will notify you by phone when your application package has been reviewed.

How do I schedule an inspection?

Inspection scheduling must be made 48 hours in advance.
It is important that you check with other agencies as needed (i.e. Fire Department) before scheduling an inspection with DEH.
