ENB Region 3 Completed Applications 09/20/2006

The applicant proposes to to construct a roadway crossing of State-designated Freshwater Wetland PV-2 (Class II) to serve a proposed 10-lot residential subdivision to be known as Tamarack Heights.  The project site is located on a 37.9 acre parcel located generally on the west side of Tamarack Hill Drive.  As proposed the 30-foot wide crossing would result in the permanent loss of about 0.29 acre of State-designated wetlands and 0.22 acre of regulated 100-foot adjacent area.  To offset wetland losses, the expansion of Freshwater Wetland PV-2 by 0.35 acres is proposed elsewhere on the site.  In addition, a Stormwater Pollution Prevention Plan has been prepared and will be implemented in accordance with the SPDES General Permit for Stormwater Discharges from Construction Activities (GP-02-01).  A portion of one stormwater detention basin would also be located within the regulated 100-foot wetland adjacent area.

The applicant proposes to expand the currently permitted 5.4 acre pond by approximately 0.6 acre within the existing mining limits, and replace the existing 63 tons per hour dry screen with a new screen with a processing capacity not to exceed 150 tons per hour.  No change in the existing limits of mining are proposed.  The proposed reclamation objective for this site is an open-water pond of six (6) acres.

The applicant proposes to modify a portion of Freshwater Wetland OL-42 (Class III) and its 100 foot adjacent area to construct an access roadway, stormwater detention basin, and drainage improvements in conjunction with the construction of a ten (10) lot residential subdivision on a 35+acre parcel. The total area of disturbance to the wetland is 0.33 acre; the total area of disturbance to the adjacent area of the wetland is 1.39 acre. Approximately 0.37 acre of new wetland will be constructed within the adjacent area at the project site as mitigation; an additional 0.31 acre of shallow water quality basin is designed to incorporate wetland features. The project is located on the south side of Lockwood Lane, approximately 1000 feet east of Barrett Hill Road in the Town of Carmel, Putnam County. A stormwater management plan has been prepared and is available for review.

The applicant proposes to modify a portion of Freshwater Wetland L-13 (Class II) and its 100 foot adjacent area in order to construct various improvements to an existing single family residence on the northeastern shore of Lake Waccabuc, Class A. Activities proposed within the Freshwater Wetland are extension and repair of an existing boardwalk, removal of an existing underground storage tank (UST) and shed,  addition of a grinder pump to the existing septic system, and planting of native wetland vegetation as mitigation; activities proposed within the adjacent area include reconstruction of an existing garage, replacement of an existing paved parking area with new gravel parking area, and planting of native wetland vegetation as mitigation. The total area of disturbance to the Freshwater Wetland is less than  0.01-acre; the total area of disturbance to the adjacent area is 0.025-acre. The project is located on the south side of Cove Road, west of Oscaleta Road in the Town of Lewisboro, Westchester County.

The Department has made a tentative determination to approve this application for a new SPDES permit for an existing surface discharge from an outfall (Catskill Influent Chamber) at the Kensico Reservoir (Class AA).  The outfall ( No. 001 ) is located near the northern terminus of the Kensico  Reservoir and reflects the routine transfer of approximately 400 million gallons per day (MGD) of drinking water from Ashokan Reservoir to Kensico Reservoir via the Catskill Aqueduct as part of on-going drinking water supply operations for the City of New York.  Aluminum sulfate (alum) and sodium hydroxide (caustic) may also be added periodically to the discharge in order to control turbidity and enhance disinfection. Additions of these treatment chemicals would be conducted at the existing Catskill Alum Plant (CATALUM) located in Pleasantville in the Town of Mount Pleasant, and would occur only after the NYS Department of Health has determined that such treatment is necessary to protect public health. The draft permit contains requirements intended to minimize the duration of such chemical treatments, and includes monitoring and reporting of flow, turbidity, total suspended solids (TSS), and temperature.  The project involves no new construction.  Outfall No. 001 is located near the northern terminus of the Kensico Reservoir, south of Nannyhagen Road in the Town of Mount Pleasant, Westchester County. A revised draft permit is available for inspection and comment at the regional office.  This Notice supercedes the Notice of Complete Application which was published the week of February 13, 2006.
