Section 9 Summary of Coordination and Environmental Compliance
EAA Storage Reservoirs Revised Draft PIR and EIS February 2006
9-12
32 of the 34 tracts. The Phase I ESAs identified 193 areas of concern ranging
from maintenance areas, to mix and load and staging areas chemical storage
buildings, to petroleum storage tanks, pump station, and refueling areas to
former airstrips. Three of the tracts within the project area, the Rotenberger
Wildlife Management Area, the Holey Land Wildlife Management Area and the
Talisman South Ranch #100-1002 have not been formally evaluated.
Of the 193 areas identified, a total of 59 areas warranted no further actions after
conducting the Phase II ESA. Additional assessments and/or corrective actions
beyond the Phase II ESA were conducted at 117 areas. The data from these
additional assessment/corrective action activities were submitted to the FDEP.
At tracts where ERAs were conducted, the data was submitted to the FWS. No
Further Actions (NFA), Site Rehabilitation Completion Orders (SRCO), or
concurrences were issued to each of the 117 areas by these two regulatory
agencies. Only 17 areas remain out of the 193 areas identified that will require
additional assessments, are being completed, or will require corrective actions.
None of these remaining areas lie within the project area with the exception of
the Woerner Farm #3 parcel. Recent post-remediation testing of the Woerner
Farm #3 property located in the northernmost portion of the Cell #1 footprint
yielded elevated levels of toxaphene. The Fish and Wildlife Service (FWS) has
performed an environmental risk assessment and determined that toxaphene, at
possible action levels, is widely distributed I the shallow soil layer within the
Woerner Farm #3 area. However, no final determination has been made and the
FWS is currently coordinating with the SFWMD to develop a plan of action for
final closure of the site.
Sediments in the primary canals (Miami, North New River, Cross, and Bolles)
have been sampled and analyzed in conjunction with the SFWMD DBHYDRO
database.
The data indicates that the sediments contain persistent pesticides – DDT and
its degradation products being the most prevalent. However, the sum of DDT
and DDT products in recent samples reaches one- to five-tenths of a milligram
per kilogram of sediment [0.1 mg/kg (ppb)– 0.5 mg/kg (ppb)], which is below the
State’s action levels (3300 ppb—Chapter 62-777, F.A.C Table 2: Soil Clean-up
Target Levels) and SQAGs (Sediment Quality Assessment Goals—1.19 ppb).
Sampling of the sediment will occur during construction. Proper handling and
disposal of contaminated sediments will consist of: 1) measuring levels of
pesticides in sediments, 2) avoiding disturbance of contaminated sediments
where possible, and, 3) isolating removed contaminated sediments and
placement of those sediments in a manner so as to inhibit the migration of
contaminants. Given adherence to the above specifications, this project is in
compliance with the Acts.
