The Department proposes to issue a Title V Facility Permit modificaiton for the application that was received for Glens Falls Lehigh Cement Company, Cementon Facility, located at 120 Alpha Road, off Route 9,  Town of Catskill, County of Greene,  owned by Glens Falls Lehigh Cement Company, Inc., 313 Warren Street, City of Glens Falls, Warren County.

The facility consists of cement finish grinding, packaging, and shipping operations, and an associated quarry.  Major equipment includes stone crushers, storage silos, a rotary slag dryer, roll press, three finish mills, and packaging/bulk loading (for trucks and rail cars) equipment.  The facility also includes marine loading/unloading operations which occur at the facility's docks.  The Alsen property (adjacent, contiguous, and under Glens Fall Lehigh's control) provides additional storage and dock capacity.

This draft permit modification (ID 4192600001/00110) is for the Cementon Title V air permit.  As a result of this modification, the facility will now be subject to PSD (prevention of significant deterioration) regulations for PM10 particulate emissions.  All other contaminates will be capped below PSD triggering thresholds.  PM10 stack emissions are proposed to increase by 151.23 tons per year.  Other air contaminants are described as increasing also: NO_x by 27.42 tons per year (tpy), CO by 6.86 tpy, SO² by 39.75 tpy, VOC by 0.27 tpy, and HAP’s by 0.08 tpy.  Based upon air modeling ambient PM10 increases at receptors are projected to be 5 ug/m³ (24 hour) and 1 ug/m³ (maximum annual) with total and existing ambient PM10 levels at 52 ug/m³ (24 hours) and 17.3 ug/m³ (maximum annual).  Both of these levels are below the NAAQS (National Ambient Air Quality Standards) of 150 ug/m³ (24 hour) and 50 ug/m³ (maximum annual). This modification involves increased hours of operation for the slag dryer (1600 hpy increased to 6,000 hpy) and bin vent bag house dust filter installed on cement storage silos (1600 hpy increased to 8760 hpy), and converted roll press and finish mill 3, and the Klinker Hall (675 hpy increased to 8760 hpy), and removal of Special Condition 37 limiting operations at the Alsen Dock. The net reduction of 39.38 tpy of fugitive dust emission due to truck traffic on unpaved roads between Alsen Dock and on-site and off-site destinations would therefore no longer apply.  Applicant will continue to utilize fugitive dust control practices as enumerated in an approved 1994 fugitive dust management plan on site to control fugitive dust related to transportation of materials from the Alsen dock to Alsen storage areas or to the slag dryer and clinker hall areas of the GLFC facility. This draft permit also includes the requested construction of a truck/rail unloading station with associated material conveyors and dust collectors (emission points TRUL1 and TRUL2) and enclosure of the Klinker Hall. Only the UALSEN, UCLTRN, URMHND, USHPNG, UFINML, and USGDRY emission units contain changes.  S02 emissions will be capped below the psd triggering threshold at 39.75 tons.  S02 will be limited by limiting the hours of operation for the slag dryer to 6000 hours per year.  By taking fuel use (hours) as a federally enforceable limit, all other contaminates except for PM10 will be capped below PSD triggering thresholds.  Emissions will be tracked on a 12month rolling total basis, using production data, operating hours and published emission factors to calculate actual emissions.  Records will be made available to agency representatives upon request.

    

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 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 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 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 exists.  A copy of the Department’s permit hearing procedures is available upon request or on the Department’s web site at http://www.dec.state.ny.us/website/ohms/gudph1.htm

The modification ID number 4-1926-00001/00110 is available for review at the Region 4 office.  The contact person is Wendy Dubois, NYSDEC, 1150 North Westcott Road, Schenectady, NY 12306-2014, telephone (518)357-2069. Comments will be received for 30 days from the date of this notice.  If comments are received which raise significant issues or provide additional relevant information, the Department may modify the draft modified Title V Facility 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.
