Section 2 Existing Conditions/Affected Environment

EAA Storage Reservoirs Revised Draft PIR and EIS February 2006

2-50

2.17.3 Stormwater Treatment Areas

Within the EAA, there are a total of five STAs. All five of these STAs are in flow

through operations. One of these STAs, STA-3/4, is located adjacent to the

proposed EAA storage reservoir. A sixth STA, STA-1E, although not physically

located in the EAA, upon completion, will receive EAA runoff via the STA-1

Inflow and Distribution Works project located between STA-1W and STA-1E.

These man-made wetlands offer a potentially valuable recreational resource.

Recreational plans are being developed for the STAs to ensure that recreational

uses are consistent with the primary use of the STAs- to achieve specific water

quality improvements. To date, hunting has only been permitted in STA-5. The

annual FWC report for the 2002 to 2003 waterfowl hunt season indicated that

for this particular STA, 500 hunters were permitted and 1,715 ducks were

harvested. Supervised bird watching events have also been held recently in

some of the STAs.

The projects in the October 27, 2003 Everglades Protection Area Tributary

Basins Long-Term Plan for Achieving Water Quality Goals (Long-Term Plan)

were designed to achieve compliance with the water quality standards for the

EPA by December 31, 2006. One of the key assumptions during the development

of the Long-Term Plan was that Compartments B and C would be under

consideration for use as part of the EAA Storage Reservoirs Project through

Fiscal Year (FY) 2010 and for this reason should not be considered for other

Everglades restoration uses until FY 2011. Subsequent to completion of the

Long-Term Plan, it was determined that all of the EAA Storage Reservoirs

Project’s water storage goals could be achieved on Compartment A, and that

using Compartments B and C would not be a cost effective way to meet the

storage objectives of the EAA Storage Reservoirs Project (Phase 1 and 2). In

light of the availability of the land in Compartments B and C, the SFWMD

proposed to initially expand STA-2 with a new 2,000-acre Cell 4 and to initially

expand STA-5 with a new 2,055-acre third flow-way to assist in maximizing the

treatment effectiveness of the STAs in improving water quality entering the

EPA. The SFWMD submitted a revised Part 2 of the Long-Term Plan to the

FDEP in November 2004, requesting approval to revise the Long-Term Plan to

include the addition of STAs on Compartments B and C, including the initial

expansions. FDEP approved this request in December 2004. The initial

expansions, which are currently in the design phase, are scheduled to start

construction in January 2006 and to be flow-capable by December 31, 2006.

On a parallel path with the development of the EAA Storage Reservoirs Project

PIR, the SFWMD is proceeding with the design of additional treatment areas on

the remaining acreage of Compartments B and C to further assist in maximizing

the effectiveness of the STAs in improving water quality entering the EPA. A

Regional Feasibility Study which has been underway during 2005 is intended to
