ENB Region 9 Completed Applications 08/01/2007
The Department is proposing to modify the SPDES permit for the Dunkirk Generating Station. This facility is located on Lake Erie and contains four units with a total electrical generating capacity of 600 megawatts. The facility has a design capacity of 576 million gallons per day of condenser cooling water with the cooling water intake structure located on the lake shoreline at the entrance to Dunkirk Harbor. Water withdrawn from the lake passes under a skimmer wall and into a forebay containing a pair of trash racks with vertical bars spaced 7.6 cm apart. From the forebay, two separate intake tunnels travel several hundred feet each to a screenhouse, where intake screens operate to keep material from plugging the Station's condensers. Screenhouse No.1 contains three dual flow traveling intake screens that serve Units 1 & 2. Screenhouse No.2 contains four dual flow traveling intake screens servicing Units 3 & 4. Installation of new dual flow traveling intake screens containing fish protective features was completed in July 2000. The screens wash continuously and all fish and debris are transported back to the lake through a dedicated fish return line which was completed in December 1996.
This SPDES permit authorizes the discharge of condenser cooling water, screen wastewater, treated wastewater, boiler blowdown, demineralization regeneration wastes, bottom ash sluice water, ash hopper overflow, roof drains, floor drainage, and storm water to Dunkirk Harbor and Lake Erie.
The modifications to the SPDES permit being contemplated by the Department includes additional permit limits for certain parameters, reduction in existing permit limits in accordance with water quality-based effluent limitations for certain parameters, a requirement for the submission of a work plan for evaluation of the effect of the existing coal pile on groundwater, and Biological monitoring requirements required by Subpart J of the 40 CFR 125 applicable to cooling water intake structures for Phase II existing facilities under Sec. 316(b) of the Clean Water Act. The Biological monitoring conditions require NRG Dunkirk Power LLC to submit data and analyses related to the once-through cooling system. The information will be utilized by the Department to determine best technology available for minimizing adverse impacts to the aquatic resources of Lake Erie. NRG Dunkirk Power LLC will also be required to review possible technologies and operational measures to minimize aquatic impacts. The information is being requested pursuant to 6 NYCRR Part 704.5 and 40 CFR 125 - Subpart J.
Effluent limits for Outfall 005 were relaxed based on newly determined dilution factor of 12.31 to 1. Effluent limits for Outfalls 003 and 006 were also relaxed based on these outfalls discharging to Outfall 001 instead of directly to Dunkirk Harbor.
The Dunkirk Generating Station is located on the Lake Erie, Dunkirk Harbor, in the Town of Dunkirk, Chautauqua county, New York.
A copy of the draft SPDES permit and fact sheets are available for review at the DEC Region 9 office or by calling the contact listed below.
The Department has prepared a Draft Permit and has made a tentative determination to approve this application to renew the existing Title V Permit for sponge making operations at the 3M facility. The facility had 3 permit modifications during the past Title V permit term which included installation of continuous sponge casting equipment, replacement of the old boilers with new units that burn natural gas and low sulfur oil subject to New Source Performance Standards, Subpart Db, and replacement of the salt reclamation process with new control equipment. Also included in this renewal are the requirements of the National Emission Standards for Hazardous Air Pollutants (NESHAP) for cellulose products manufacturing (40 CFR 63 Subpart UUUU). Existing sources were required to be in compliance by June 13, 2005. This NESHAP specifies a 75% reduction in emissions of carbon disulfide and carbonyl sulfide from the cellulose sponge operations. State Regulation 6NYCRR Part 212.10, promulgated in 1995, required 81% overall control for Volatile Organic Compounds emitted from the same source. The requirement for monitoring carbon bed regeneration cycle parameters listed under 40 CFR 63.55059b0 Table 2 is being satisfied by the operation of continuous emission rate monitoring of carbon disulfide on the inlet and outlet of the carbon absorber. The requirement to monitor the bypass vent on both the solvent recovery unit, Emission Point NCS01, and the regenerative thermal oxidizer emission point, SEPAR, is being met by the use of a valve positioning sensor with an electronic recorder. Both of these alternatives have been accepted by the USEPA.
Arcade, NY 14009-1109
The Department has drafted a 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 has made a tentative determination to approve this application for renewal of the existing facility-wide Air Title V permit for the applicant's manufacturing operations located at 400 Main Street, Arcade, NY. Prestolite manufactures large and small frame alternators, large starter motors and electro-mechanical instruments. Prestolite also manufactures programmable electronic speedometer and tachometer instruments for medium and heavy duty trucks, and for agricultural and industrial equipment.
The company has accepted facility-wide limits on total Hazardous Air Pollutant (HAP) and individual HAP emissions below 25 tons per year and 10 tons per year, respectively, to avoid applicability to 40 CFR 63 Subpart DDDDD/NESHAP for Industrial Boilers, 40 CFR 63 Subpart MMMM/NESHAP for Surface Coating of Miscellaneous Metal Parts and Products and 40 CFR 63 Subpart PPPPP/NESHAP for Engine Test Cell/Stands. Nitrogen oxide (NOx) emissions from emission unit P-00009 are limited to less than 50 tons during any consecutive 12 month period to avoid applicability to 6 NYCRR Part 231-2/New Source Review and 6 NYCRR Part 212-10/NOx Reasonable Available Control Technology (RACT). Volatile Organic Compound emissions from emission unit P-00001 are limited to less than 28,800 pounds for any consecutive 12-month period due to the establishment of Emission Reduction Credits under 6 NYCRR Part 231-2. Surface coating processes are subject to RACT for VOC emissions under 6 NYCRR Part 228. The company has requested a variance from RACT requirements for the use of non-compliant coatings.Particulate and visual emissions are subject to allowable rates and opacity limits.
