DescriptionFEDINC was the prime engineer, contract administrator and construction manager for the implementation of surface water management and wetlands reclamation at the Triangle Lakes Spillway, Hines Energy Complex in Polk County, Florida. The project involved the site of several 1,000 MW gas fired electric power generating plants on 7,680 acres. Prior to its acquisition by Progress Energy, the site was highly disturbed by surface mining activities spanning the previous 25 years. FEDINC engineered the overall site restoration plan and managed restoration activity program applications to the Florida Department of Environmental Protection, Bureau of Mine Reclamation (FDEP), Southwest Florida Water Management District (SWFWMD) and U.S. Army Corp of Engineers (USACE) dredge and fill permits for construction of earthworks on lands tributary to waters of the state, including USACE mitigation and the creation of wetlands on a 582-acre mitigation area. Following approval by the agencies above, FEDINC managed all earthwork and re-vegetation activities on 6,976 acres contiguous to the plant site island (704 acres) consisting of 1,916 acre Buffer area, 722 acre cooling pond, 311 acre Brine Pond, 470 acre McCullough Creek Water Shed and 3,672 acres of Water Crop Area.

DESCRIPTION Cont.: FEDINC engaged in extensive field survey work to re-establish historic flows and hydro periods for the wetland elements of the restoration plan. Numerous detailed design packages, bid specifications and construction administration services were provided to Progress Energy in support of these activities. FEDINC continues to administer contractor activities, certify periodic progress payments, monitor re-vegetation activities, survey uplands and wetlands for establishment success and individual species survival and NPDES water quality. The project includes design and construction of outfall structures, weirs, flumes and spillways such that all excess storm water is collected, treated and conducted off the property to NPDES discharge locations. FEDINC as a part of the design and permitting process, performed hydrology and hydraulic modeling studies utilizing state-of-the-art (ICPR3, HEC-1, HEC-2, HEC-RAS) and other FEMA approved software to compare pre-disturbance and post-construction storm water run-off for 25, 50 and 100 year storm events as well as to assist in the design on internal water conveyances to maintain water table levels appropriate for the wetlands design. FEDINC as a part of the engineering design and permitting process created environmental management maps utilizing ArcInfo proprietary Geographic Information Systems (GIS) software to assist in the initial design and in monitoring criteria for compliance with permits. FEDINC continues to provide engineering; administration and construction management services to Progress Energy Corporation on a routine basis and is a Master Services provider to Progress Energy Corporation. |
