ENB Region 3 Completed Applications 04/26/2006

    The Department has prepared a Draft Permit pursuant to Article 19 (Air Pollution Control) of the NYS Environmental Conservation Law (ECL) and Title V of the Federal Clean Air Act Amendments and made a tentative determination to approve this application for the Applicant’s Title V Permit Renewal.

    The Dutchess County Resource Recovery Facility located in Poughkeespie, New York is a Class 1 Small Municipal Waste Combustor facility.  The facility has two O'Connor Rotary mass burn waterwall type combustors each capable of combusting 228 tons per day of  municipal solid waste (MSW), recovering energy as steam in the two boilers which have the capability to produce 115,800 lb/hour of steam at 625 psig and 700 degree Fahrenheit.  The steam is used to drive a 9.2 MW turbine generator.  Excess electricity is sold to Central Hudson Gas & Electric  Corporation.  The primary fuel combusted is MSW.  During startup and shut down operations, natural gas is fired to maintain minimum flue gas temperature.  The primary SIC is 4953.

    Air pollution control equipment at the facility includes a spray dry absorber for acid gas control, fabric filters for particulate removal, and a carbon injection system for mercury and total dioxin control.  The permittee may elect to not operate the carbon injection system(s) if annual stack test results demonstrate compliance with Subpart BBBB mercury and total dioxins emission limits without the operation of the carbon injection system(s).  An overfire air system for carbon monoxide control is currently being designed and the anticipated completion date is Fall 2006.  The facility has a Continuous Emissions Monitoring  System (CEMS) .

    The facility is subject to 40 CFR 60 Subpart BBBB, Emission Guidelines for Small Municipal Waste Combustors, and 6 NYCRR Part 219, Incinerators.

    By acceptance of this permit, the permittee agrees that the permit is contingent upon strict compliance with the ECL, all applicable regulations, the General Conditions specified and any Special Conditions included as part of this permit.

    In accordance with 6NYCRR Parts 621.5(d)(9) and 201-6.4(c), the Administrator of the United States Environmental Protection Agency (USEPA)  has the authority to bar issuance of any Title V Facility Permit if it is determined not to be in compliance with applicable requirements of the Clean Air Act or  6NYCRR Part 201.

    Persons wishing to inspect the subject Title V files, including the application with all relevant supporting materials, the draft permit, and all other materials available to the DEC (the "permitting authority") that are relevant to this permitting decision should contact the DEC representative listed below.  It is recommended that an appointment be made to confirm the availability of the subject files.  The DEC will endeavor to make the files available within two (2) business days of contact, during normal business hours (8:30 am through 4:45 pm), unless the requestor wishes to inspect the files at a later date.

    DEC will evaluate the application and the comments received on it to determine whether to hold a public hearing.  A public hearing may be legislative or adjudicatory.  A legislative public hearing is a proceeding which provides an additional opportunity for public comment.  DEC’s determination to hold a legislative public hearing will be based on whether a significant degree of public interest exists.   If a legislative public hearing is to be held, a Notice of Hearing will be published which will include the time and place of the hearing and submitting comments.   The applicant and all persons who  have filed comments on the permit will be notified by mail of the public hearing.  Comments and requests for a legislative public hearing should be in writing and addressed to the Department representative listed below.

    An adjudicatory public hearing is a trial type proceeding which provides the opportunity for adjudication on the basis of evidence, including direct testimony and cross examination.  An adjudicatory hearing is held only if substantive and significant issues relating to any findings or determinations the Department is required to make pursuant to the Environmental Conservation Law exist.  A copy of the Department’s permit hearing procedures is available upon request or on the Department web site at: http://www.dec.state.ny.us/website/ohms/gudph1.htm.

The State Pollutant Discharge Elimination System (SPDES) permit for the Village of Suffern Sewage Treatment Plant (STP), SPDES Number NY 002 2748, in Rockland County has been modified in accordance with New York State’s  Environmental Benefit Permit Strategy (EBPS).  

The permit was modified in the following ways:

Permit pages -

Updated permit pages are used, based on current Department guidance, format and nomenclature.

Permit pages are renumbered and reordered.

The address for the Bureau of Watershed Compliance and for the Regional Water Engineer on the Recording, Reporting and Monitoring page have been updated.

Permit Limits, Levels and Monitoring -

Mass limits - Mass limits for UOD and TSS were rounded to 2 significant figures in compliance with DEC guidance in the DMR Manual for Completing the Discharge Monitoring Report for the SPDES, NYSDEC, February, 2002.

Influent sampling - The influent sampling requirements for TKN, Ammonia, pH, Settleable Solids, and Temperature have been removed from the permit.  This information is no longer required.

Phosphorus sampling - The State of New Jersey has recently been conducting Total Maximum Daily Load (TMDL) studies for phosphorus.  It is now necessary to collect effluent phosphorus data to establish baseline phosphorus loads for The Village of Suffern STP.  A phosphorus monitoring requirement has been added to the permit.  A phosphorus limit may be necessary in the future.

Ammonia limits - A new USGS hydrological study has been completed for the Ramapo River.  The updated stream hydrology information was used to recalculate the Water Quality Based Effluent Limits (WQBEL). The new WQBEL for ammonia during summer months has been changed from 6.3 mg/l to 5.6 mg/l.  The new WQBEL for ammonia during winter months has been changed from 19.5 mg/l to 16.0 mg/l.

Cyanide limits - Due to the updated hydrology, a new water quality limit has been calculated for cyanide.  The cyanide limit has been changed from 0.9 lbs/day to 0.4 lbs/day.

Methylene Chloride action level - Due to the updated hydrology, a new action level has been calculated for methylene chloride.  The action level for methylene chloride has been changed from 0.7 lbs/day to 0.4 lbs/day.

    The Department of Environmental Conservation (DEC) has received an application to re-issue/re-new  the following pre-existing EPA minor Private/Commercial/Institutional State Pollutant Discharge Elimination System (P/C/I SPDES) permit.  DEC has made a tentative determination to re-issue/re-new this permit for a standard ten year term maintaining current effluent limitations and monitoring and reporting requirements.  This permit involves the subsurface discharge of up to 14,000 gallons per day of treated sanitary waste.  Nearest waterbody:  Beaverdam Brook.

    Additional information on this permit may be requested from or inspected at the NYSDEC Central Office in Albany.  Substantive comments must be submitted in writing to the contact person.

    SPDES #:  NY 023 3307

DEC has tentatively determined to issue an Article 15 Stream Disturbance permit to the above referenced applicant for installation of rip-rap and vegetation to 400 linear feet of shoreline along the Esopus Creek for restoration and repair of the nearly-vertical eroded bank resulting from storm/flooding events in the spring of 2005.   The project site is located due north of the City of Kingston and Town of Ulster border where it intersects and begins to follow the Esopus Creek south.
