Application ID:


Permit(s) Applied for:

Article 19 Air State Facility

Project is Located:

Le Roy, Genesee County

Project Description:

Lapp Insulators LLC has submitted an application to replace its Title V Facility Permit, originally issued August 10, 1999, with an Air State Facility Permit, to reflect changes in operations. Lapp Insulators manufactures ceramic and silicone rubber electrical insulators. The changes include removal of a natural gas fired kiln, two gas fired dryers, and two paint spray booths, and the addition of nine gas fired insulator mold dryers and a gas fired oven.

Facility operations include: natural gas fired boilers; clay insulator mold cutting and forming operations; natural gas fired dryers for clay insulator mold drying; gas fired kiln dryers for clay insulator mold drying prior to final firing; gas fired tunnel kilns for firing finished clay insulator molds; gas fired periodic kilns for firing finished clay insulator molds; a gas fired silicone rubber bonding oven; metal part coating operations; a gas fired air compressor; silicone spraying operations; and insulator cap cement filling operations.

Lapp Insulators proposes limiting boiler and kiln operation to restrict facility emissions of oxides of nitrogen (NOx) to 88.2 tons per year, below the 100 ton per year applicability thresholds of 6NYCRR Part 201-6 Title V Facility Permits, Part 212.10 Reasonably Available Control Technology (RACT) for Major Facilities, and Part 227-2 RACT for Major Facilities of NOx.
The facility was previously subject to Part 201-6 Title V Facility Permits due to potential emissions of particulates in excess of 100 tons per year. Removal of process sources and limited boiler and kiln operation limiting NOx emissions will also reduce potential particulate emissions to below the 100 ton per year Title V threshold.

The application and Draft Permit are available for review at the Department's Region 8 office at the address indicated below. The Draft Permit is also available as a .pdf file at: http://www.dec.ny.gov/dardata/boss/afs/draft_asf.html
