Storage Tank Modification Requirements
Broward County Storage Tank Construction/Closure Modification Requirements
|Installation of an underground or above ground storage tank|
Aboveground storage tank systems with capacities greater than 550gals and underground storage tank systems with capacities greater than 110gals are subject to Broward County Chapter 27, Article X, Storage Tanks regulation.
A Broward County Storage Tank Facility License (License) is required prior to building, erecting, operating, modifying, closing or replacing in whole or in part any storage tank system that is intended to store hazardous material in Broward County. The License approval process consists of the review of a Broward County Storage Tank Facility License application along with engineering drawings signed and sealed by a Professional Engineer (P.E.) registered in the state of Florida. Steps taken to approve the application package are summarized in the following checklist.
Special Note: Effective 2/26/2013, Chapter 27, Pollution Control, of the Broward County Code of Ordinances (Code), Article X, Storage Tanks, no longer requires Stage II Vapor Recovery (Stage II) Systems be installed at Gasoline Dispensing Facilities (GDF). However, GDF owners or operators with existing Stage II systems must either continue to maintain and operate their systems in accordance with the Ordinance or file for a License Modification approval/permit to close, remove, or decommission their Stage II system in accordance with the Code. It shall be prohibited to dismantle, remove, disconnect, cease to operate, close or decommission Stage II systems without applying for, and obtaining a License Modification approval prior to performing any of the aforementioned activities. A copy of the Code changes may be obtained by clicking on the following link: http://www.municode.com/ or contacting Greg Whitaker at (954) 519-1229 or firstname.lastname@example.org or Alfred Reid at (954) 519-1432 or email@example.com.
This checklist is created to serve as a guide to the owner/operator, contractor, or engineer through the Pollution Prevention Division (PPD) storage tank modification/construction approval process.
Storage Tank Facility License Application:
PPD now processes electronic permitting (aka ePermits) and strongly encourage applicants to file their applications online. All documents including License application, engineering plans, permit fees and License approvals are processed online and can be accessed by following directions on the following website: http://www.broward.org/ePermits/Pages/Default.aspx. Following are alternative and other steps needed to complete your License application.
A License application may also be obtained at the PPD, 1 N University Drive, Plantation, Florida 33324, by calling PPD at (954) 519-1260 or by clicking the following PPD link. The License application package, consisting of the Storage Tank Facility License application and 4 sets of signed and sealed engineering plans, must be submitted to the PPD for approval prior to commencing storage tank construction, closure or modification activities.
Complete items 1 through 19 on the application. PPD will perform a preliminary administrative review of the application and determine the License fee to be paid.
The specifications in item 11 (Storage Tanks) must be consistent with the requirements of Chapter 27, Article X, Storage Tanks, Broward County Code; Chapters 62-761, 62-762, and 62-252 Florida Administrative Code; Florida Building Code; Broward County Local Amendments to the Florida Fire Prevention Code and reference standards as listed in these codes. (See list of Reference Standards below).
If a Stage II Vapor Recovery System (this is no longer required or recommended) is intended to be installed, complete item 12 (Stage II Vapor Recovery). The specifications in item 12 must be checked against and be consistent with the accompanying engineering plans and the current California Air Resource Board (CARB) Executive Orders Stage II Vapor Recovery Systems. Click here to view the current CARB Executive Orders. (See Special Note above).
If item 13 is answered “YES” indicating de-watering will take place during the construction or if the facility is listed on the Environmental Assessment & Remediation (EAR) Section’s list of contaminated sites, the engineering plans will be reviewed by the EAR Section. Click here to view contaminated sites and their locations. De-watering activities at/or within 1/4 mile radius of contaminated sites will be reviewed by the EAR Section and will require additional information prior to approval. Click here to view information regarding de-watering
Item 19 (Applicant’s certification) must be completed and signed by the owner/operator or authorized agent. The Pollutant Storage System Specialty Contractor (PSSSC) must also complete and sign this section for construction/modification involving underground storage tank systems.
