ENB Region 3 Completed Applications 07/13/2005

THIS IS A REVISION AND RE-NOTICE OF A NOTICE OF COMPLETE APPLICATION ORIGINALLY DATED NOVEMBER 22, 2004.

            The Palumbo Sand and Gravel Company proposes an 18-acre downward expansion into groundwater in order to mine from 30 to 55 feet below the current mine floor, within the eastern half of their currently approved sand and gravel mine.  The 18-acre area would be located a minimum of 200 feet from the east bank of the Swamp River.  It would allow excavation of  approximately 1,000,000 cubic yards of sand and gravel over approximately 10 years, for processing at the Company’s existing processing facility and sale to customers.  

    Mining to this depth will result in mining below the groundwater table, which is estimated to be at least 5 feet below existing floor of the mine.  Reclamation of this 18-acre excavation would be to create an 18-acre lake.  This area is outside the 100-year floodplain and is also separated from the Swamp River by a vegetated berm, ranging in height from 4 to 8 feet high and from 30 to 40 feet wide at its base, which parallels the Swamp River along the full length of the 18-acre excavation area.  The resulting sand and gravel would continue to be trucked over the Company’s existing bridge on the Swamp River to be processed at the Company’s existing processing facility.  Blasting will continue to be prohibited at the site.

    This proposed 18-acre modification to the Company’s mining and reclamation plan is located within the 92-acre area currently mined by the Company under a Mined Land Reclamation permit at the intersection Sherman Hill Road and NYS Rt. 22 in the Town of Dover, Dutchess County.

    A Negative Declaration for this Type I Action has been pepared by this Department, as Lead Agency, and is available through the Contact Person listed below.

       The applicant, Somers Chase Waterworks Corp., has applied for a Water Supply permit to develop one new well, known as Well #3, to be pumped at a rate of 30 gallons per minute (gpm), to serve the approximately 99 homes in the Kenilworth Subdivision. Well #3 is a 500 foot deep, bedrock well, with steel casing down through the first 72 feet to prevent surface waters from draining into the aquifer.  The applicant submitted the results of a 72 hour pumptest, which showed that the well can safely produce 30 gpm. This well would be combined with the applicant's existing Well #1 rated at 50 gpm and Well #2 rated at 90 gpm.  All three wells would be managed together to produce an average of 61 gpm, which is the equivalent of 88,200 gal. per day.

       The applicant is also proposing to construct a 2000 foot long pipeline to pump the water back to the main wellfield.  A portion of the pipeline would be through the 100-foot wide adjacent area of state regulated Freshwater Wetland #F-76 (Class 2) and under a culvert containing Hallocks Mill Brook [Class B-ts].

        Well #3 is located just off Hallock's Run Road near the intersection of Voris Drive, in the Kenilworth Subdivision, in the Lincolndale section of the Town of Somers, Westchester County, NY
