From: Oliver, Belinda To: Taylor Morgan Cc: dsimpson@pinellascounty.org; tcalvit@pinellas.gov; Tamara Miranda-Juarbe; Antonio Serbia; SWD_WF_Permitting Subject: RE: 53rd Ave. N. Force Main Replacement FDEP Permit Date: Thursday, September 7, 2023 8:55:00 AM

Good morning Ms. Morgan, In consideration of all aspects of the project: 2,598 LF 20-inch fusible, C-900 PVC, 170 LF C-900 PVC to be installed, adjacent to the existing gravity main of approximately 2,756 LF of an existing 20-inch and 24-inch concrete cylinder pipe; with the purpose of addressing the existing facility’s deteriorated conditions. Whereby, the existing force main has ruptured twice within the projects limits, resulting in sewage spills in the street and adjacent private properties.

Although technically, the 24-inch portion of the existing could be permitted when I consider that first the pipe size is not being increased but decreased to a uniform capacity that matches most of the existing force main; when I consider the purpose of the replacement which is clearly maintenance to a failed system, then in my professional opinion the project can be exempted based on 62-604.600(2)(e) F.A.C. “Modification associated with routine maintenance” is exempt.

However, if you prefer then the project can be permitted. Please confirm if it is your preference to obtain an official DEP permit.

Regards, Belinda Oliver, E.I.

Good afternoon Ms. Oliver, Thank you for your help thus far.

I have some concerns regarding the FDEP permit exemption status outlined below for the 53rd Ave. N. Force Main Replacement project.

To clarify, the existing force main is 20 inches in one segment, and upsizes to 24 inches in another segment. Our proposed force main will only be 20 inches, meaning that we’ll be downsizing for a portion of the project limits. Also, the proposed force main will be located adjacent to the existing force main, and will not be in the exact location of the existing force main.

Given these circumstances, does this project still qualify for exemption based on Rule 62-604.600(2)(a) Florida Administrative Code (F.A.C.) referenced below?

Thanks, Halff

Force Main Replacement FDEP Permit

Good Morning Ms. Morgan, Following a review of the application and plans submitted, it has been determined that the proposed construction project will not require a Department permit. The approximately 2,770 linear feet of 20-inch force main is replacing approximately 2,760 linear feet of 20-inch and 24-inch force main at the same location along 53rd

Avenue North.

According to Rule 62-604.600(2)(a) Florida Administrative Code (F.A.C.),

(2) The following activities do not require a collection system permit.

(a) Replacement of any facilities with new facilities of the same capacity at the same location as the facilities being replaced;

Furthermore, according to Rule 62-604.600(2)(e); Modification associated with routine maintenance is exempt.

This determination does not eliminate the necessity for obtaining any other Federal, State, or local permits that may be required for the construction of this wastewater collection/transmission water distribution system. Any deviations from the plan proposed to the Department may require another permit determination review.

If you have any further questions regarding this determination, please feel free to give me a call.
