ENB Region 5 Completed Applications 08/16/2006

A permit modification is requested for construction of two new roadway segments, associated with completion of the Greenfield Estates residential subdivision.  The additional road crossings would impact 0.17 acre of Freshwater Wetlands C-25 (class II) and C-48 (class I).  Also, a road extension, driveway, and house would be constructed in the wetland adjacent area.  About 0.66 acre of wetland has been previously restored. Proposed additional mitigation includes 1.9 acres of wetland creation and restoration of 0.37 acre of previously filled wetland.  The project is located on Ericson and Walker Drives, west of Rt. 9N, Town of Greenfield.

The applicant has proposed to re-establish the stream channel of Foster Brook (Class AA-Special), as well as enlarge its flow capacity at the lower reach in order to minimize the potential for flooding developed properties at Hulett's Landing. Storm events had destroyed the sediment retention basin, filled the channel with material, and severely eroded the banks. The current flow is also jeopardizing the sanitary sewer line which crosses the brook. The work will begin 100 feet upstream of the mouth and continue 350 feet upstream, and will consist of removing the material deposited within Foster Brook to create a 12-foot wide bermed channel with a low flow channel therein.

The Department has received a permit application to add a portable thermal desorption unit to the currently permitted facility. The portable unit will serve as a back-up unit to the existing treatment equipment during maintenance periods. Currently permitted treatment capacity will not be modified as a result of this modification. A draft permit has been prepared and is available for review at the DEC Warrensburg office.
