Agenda 04/08/2025 Item #16C6 (Certification of Financial Responsibility as required by FDEP for the renewal of the operating permit for deep injection well system at the Collier County North Regional Water Treatment Plant)4/8/2025
Item # 16.C.6
ID# 2025-893
Executive Summary
Recommendation to approve and authorize the Chairman to sign the Certification of Financial Responsibility, as required
by the Florida Department of Environmental Protection, for the renewal of the operating permit for the deep injection
well system at the Collier County North Regional Water Treatment Plant.
OBJECTIVE: To certify unconditionally to the Florida Department of Environmental Protection (FDEP) the county’s
obligation to perform plugging and abandonment of the deep injection well system at the Collier County North Regional
Water Treatment Plant (NRWTP) pursuant to Chapter 62-528 Florida Administrative Code.
CONSIDERATIONS: The NRWTP provides drinking water to customers throughout the Collier County Water–Sewer
District area. The purpose of the deep injection well at the water treatment plant is to dispose of the concentrate and
odor control blowdown flows produced by various membrane water treatment processes. The permit, which expires
June 15, 2025, is for Injection Well 2 (IW-2) located at the NRWTP.

The permit renewal application requires the county to complete and execute a Certification of Financial Responsibility
form. This form certifies that the county will be unconditionally obligated to have the financial resources necessary to
close, plug, and abandon the Class I injection well and related monitoring wells. The current plugging and abandonment
cost estimate is $811,266. In the event that the injection well system fails to meet permit conditions, or the well is no
longer required for its intended use, then plugging and abandonment become necessary.
This action is consistent with previous Board of County Commissioners decisions to approve similar requests for the
water treatment plant’s deep injection well system, most recently on December 13, 2022, as Agenda Item 16.C.11.
This item is consistent with the Collier County strategic plan objective to plan and build public infrastructure and
facilities to effectively, efficiently, and sustainably meet the needs of our community. It is further in support of the
Infrastructure and Asset Management Strategic Focus Area’s objective to optimize the useful life of all public
infrastructure resources through proper planning and preventative maintenance.
FISCAL IMPACT: The actual expenditure of funds is not anticipated and would only be required if an injection well
was to be abandoned. Funds to cover these costs, if needed, are maintained in the Reserves for Contingency line item in
the Water Sewer Operating Fund (4008), which is funded through user fees.
GROWTH MANAGEMENT IMPACT: There is no growth management impact associated with executing this
document.
LEGAL CONSIDERATIONS: This item has been reviewed by the County Attorney, is approved as to form and
legality and requires majority vote for approval. -JAK
RECOMMENDATIONS: Approve and authorize the Chairman to sign the Certification of Financial Responsibility, as
required by the Florida Department of Environmental Protection, for the renewal of the operating permit for the deep
injection well system at the Collier County North Regional Water Treatment Plant.
