Installation Permit Registration
All regulated storage tank systems must have an installation permit (which requires an application for the permit) and must be registered. A properly designed and installed tank system may prevent costly releases to the environment. The information below explains what is required to obtain an installation permit and register a tank system.
The following are installation and registration requirements for all regulated storage tank systems.
- An OPS installation permit
- Local Fire Department notification of the installation
- An installation inspection request
- Payment of the installation application/inspection fee
- Documentation of secondary tightness testing
- Registration within 30 days of putting regulated substances into the tanks
All regulated tank systems must be permitted through OPS prior to construction/installation and registered after installation. Complete and submit the appropriate AST or UST Installation Application to OPS to begin the process.
Tips for Completing the Installation Application
Do not submit the Registration form with the Installation Application. The Registration form should be submitted after the tanks are installed and in use (with regulated substance in the tanks).Download and save a copy of the form onto your computer hard drive or flash drive with an appropriate name where you can review and complete it at a later time.
- Fill out all fields. In the event that the field is not applicable, use "N/A." Lack of information will slow the approval process.
- Electronic signatures are acceptable for emailed applications. Mailed applications should be signed in ink, preferably blue ink.
- A Site Plan (electronic or printed smaller than 11 x 17) must accompany the application. It must include the following items:
- The name and address of the facility
- Lot dimensions
- Distances from tanks to nearest important building, roads, railroads, property lines, dikes/impoundment areas, existing tanks and dispensers
- Submit the application and site plan via email to firstname.lastname@example.org or mail it to the address listed on the application. Submit the application with the site plan and review fee at least 20 working days prior to beginning construction.
Installation Application Examples
Click on the images below for examples of completed installation applications.
There is a $150 application fee for the review of a UST system installation permit application. There is no fee for AST system installation permit applications.
Send your payment to the address listed on the application.
If you email the application, reference the check information for the check that was mailed to ensure quick processing.
Alternative Fuel Compatibility Form
A UST or AST system must be made of, or lined with, materials that are compatible with the substance stored therein. Product piping, including piping within the dispensers and containment sumps, is considered part of the tank system and needs to be compatible with the substance stored and dispensed through it. All tank systems that store and dispense Alternative Fuel/ Renewable Fuel must be fully compatible with those fuels. Submit the Alternative/Renewable Fuel Compatibility form to OPS when switching to alternative or renewable fuels in a tank system
Submit the form via email to email@example.com or mail it to the address listed on the form.
Change of Storage of Regulated Substance
If the regulated substance in a tank system will be changed, OPS must be notified a minimum of 30 calendar days prior to the change. The notification can be made by completing this form or by filling out the pdf version and emailing it to firstname.lastname@example.org .
Installation Application Permit Review
The turnaround time for a review is generally 20 working days. An incomplete application will be returned. The install permit approval (or denial) will be sent to the email address provided on the application, with details regarding the Installation Permit Application approval or denial.
Tips to Minimize the Time between Submitting the Installation Permit Application and Receiving Your Installation Permit
- Complete all applicable fields on the application form, including providing accurate information for the following fields:
- Owner (including a valid email address)
- Fuel system installer company
- Fire department jurisdiction
- Calibration company
- Owner certification: title, owner type (new or current), phone number, signature and date for either the owner/operator or signatory authority
- Electronically sign the application if you are submitting it via email; sign it in blue ink if you are going to mail it.
An installation permit is only valid for up to six months after it is issued. Notify your local OPS Inspector at least 72 hours before on-site tank system integrity testing (for USTs) or before a regulated substance is delivered (for ASTs). All new and used ASTs and associated connections must be tested for tightness after installation/reinstallation and before being placed in service in accordance with manufacturer instructions, or NFPA 30 where no manufacturer instructions exist.
Registration Fee Payment
Owners or operators of USTs or ASTs regulated by OPS must register their tanks within 30 days after first using them to store a regulated substance and send the registration fee. A registration invoice for the number of tanks installed will automatically be generated and sent to the primary contact at the end of the month in which tanks are placed into "currently in use" status. Make payment to OPS within the 60-day period from the date indicated on the invoice.
Tips for Paying Registration Fees
- Tank registration fees need to be paid annually.
- OPS sends tank registration and renewal invoices to the owner at the same time each year.
- The registration and renewal fee is $35.00 per tank per year.
- These fees go to the Petroleum Storage Tank Fund, which is used to assist tank owners with cleaning up petroleum releases.
- Payments can be made by using the Storage Tank Online Payment System, which allows you to make a payment with a credit card.
- If you prefer not to use the online payment system, fees can be mailed to the following address:
PO Box 628
