ENB Region 3 Completed Applications 02/08/2006

The  Department has made a tentative determination to approve this application for a new permit for a proposed discharge of 100,000 gallons per day of treated sanitary wastewater into Fishkill Creek from a tertiary treatment plant at a proposed 199-lot subdivision of 370 +/- acres called "The Springs at Beekman". Also applied for are permits for a Public Water Supply, Freshwater Wetlands (to connect to wells within the 100 foot adjacent area of wetland # PQ-8), and Stream Disturbance for the treatment plant outfall. Draft SPDES and Water Supply permits are available for review. A detailed Stormwater Pollution Prevention Plan has been prepared. The location is north and south of Beekman Road at the intersection with  Green Haven Road.

The applicant proposes to fill approximately 1/4 acre of Freshwater Wetland MB-1 (Class: 2) for a driveway serving an industrial park subdivision. As mitigation, slightly less than 1/2 acre of wetland will be created on-site.A Stormwater Pollution Prevention Plan has been prepared. The location is bordered on the west by NYS Route 416 and the north by Orange County Route 99, and is traversed east/west by Eager Road.

The applicant proposes to terminate three curtain/footing drains within the 100-foot adjacent area of Freshwater Wetland GO-5 (Class: 2) in conjunction with a subdivision of 51 +/- acres into 10 building lots. A detailed Stormwater Pollution Prevention Plan has been prepared. The location is on the west side of Foster Road approximately 1/2 mile south of the intersection with Scotchtown Road.

The applicant proposes to relocate an existing storm drain outfall structure and stabilize 180+/- feet of eroding streambank on Nakoma Brook (Class "B") with stone fill.  The location is west of Brook Street in the Village of Sloatsburg.

        The Westchester County Department of Department of Environmental Facilities has applied for a modification of the current Part 360 permit for its Sprout Brook Ash Residue Disposal Facility (the Ashfill).   

        Background:  The ashfill facility is the sole disposal facility for the ash generated by the County's nearby Charles Point Resource Recovery facility which serves the waste disposal needs of a large portion of Westchester County.  The 38-acre County facility was first permitted in 1983 and has been receiving ash since shortly thereafter.  The Ashfill currently meets all of the safeguards in the Part 360 regulations governing the design, construction and operation of this disposal facility, including a baseliner system under the ashfill, a leachate collection system to collect leachate generated by the ashfill, a groundwater well monitoring system around its perimeter and a final cover system to keep out rainwater,  which is the source of any leachate.

        Requested Modification:   The applicant requests a modification the Ashfill Part 360 permit to extend the existing baseliner system approximately 50 feet beyond the current limit along Phases 1 and 2, and to revise the operational filling sequence until the end of the facility's operational life, which is expected to be through 2009.  This will provide the County with approximately 522,000cubic yards of ashfill capacity.   This modification will raise the side slopes of the ashfill but will not increase its maximum height.

           Variance:   The applicant is also seeking a variance to allow the final cover of the ashfill to be made up of a combination geocomposite material covered by gravel throughout the landfill, instead of the geocomposite material covered by topsoil, which is normally required by the regulations.  Because the cover material is meant to hold the geocomposite material in place, the County believes substituting gravel for soil on top of the geocomposite material will satisfy this requirement of Part 360.

        The application documents are available in the Department's New Paltz office upon request.

The applicant proposes to modify a portion of the 100 foot adjacent area of Freshwater Wetland D-16 (Class I) in order to construct various improvements to an existing single family residence on a 3.89-acre parcel. Activities proposed within the adjacent area include construction of an addition to the home, a new swimming pool, new paved parking area and garage, new walkways and terraces, and a new potable water well. No disturbance is proposed within the wetland; the total area of disturbance to the adjacent area is 0.11 acre.  Although no disturbance is proposed within Freshwater Wetland D-16, approximately 0.24-acre of adjacent area of the wetland will be replanted with native vegetation at the project site as mitigation.  The project is located on the south side of Upper Shad Road, 500 feet east of High Ridge Road (NYS Route 137) in the Town of Pound Ridge, Westchester County.
