FACILITY DESCRIPTION

Voith US Inc. is an existing facility that specializes in the production of tissue and towel paper fabrics (SIC Code 2221 – Broadwoven Fabric Mills, Manmade Fiber and Silk; NAICS 313210 – Broadwoven Fabric Mills) with a synthetic minor status. The facility produces forming fabrics, including transfer fabrics and through-air drying fabrics and manufactures paper machine clothing, additionally receiving and storing rolls of yarn for subsequent use at the facility. The paper machine clothing that the facility produces consists of fabrics and belts essential to the production of tissue paper. The manufacturing processes include a natural gas-fired process heater, fabric sandblasting operations, print extruded dye (PED)/nozzle extruded die (NED) fabric printing operations, fabric cleaning operations, research and development fabric printing unit, and natural gas-fired space heaters used for comfort heating. The PED/NED fabric printing operations use room-temperature vulcanizing (RTV) silicone and xylenes as a solvent to print the design on the fabric in order to meet the specifications of some customers.

PROJECT/PERMIT ACTION DESCRIPTION

The application has not proposed any major modifications to the facility besides removing the 0.21 million BTU per hour (MMBTU/hr) Natural Gas-Fired Thermal Fluid Boiler (Emission Unit AC-001) from the permit. Emission Point AC-001 has been disconnected from service, and the facility does not have any plans to bring it back into operation.

Voith has a maximum uncontrolled potential-to-emit hazardous air pollutants (HAPs) below the major source threshold; however, the facility has requested to maintain its synthetic minor operating permit (SMOP). As such, the facility will continue maintain limitations of 24.0 tons per year (tpy) for all combined HAPs and 9.0 tpy of each individual HAP (both based on rolling 12-month totals).

1 Given the facility’s low potential-to-emit for PM, PM10, and PM2.5, the margin of compliance is expected to be significant. Therefore, no compliance demonstration mechanism is required for this standard.

NSPS APPLICABILITY

40 CFR Part 60, Subpart Dc — Standards of Performance for Small Industrial-Commercial-Institutional Steam Generating Units: This subpart is applicable to any steam generating unit (i.e. boiler) that was constructed after June 9, 1989, and has a maximum design heat input capacity of 100 MMBTU per hour or less, but greater than or equal to 10 MMBTU per hour. Since the boiler that Voith operates has a maximum capacity of less than 10 MMBTU per hour, the facility is not subject to the requirements for Subpart Dc. 

MACT APPLICABILITY

40 CFR Part 63, Subpart S — National Emission Standards for Hazardous Air Pollutants from the Pulp and Paper Industry: This subpart is applicable to processes that produce pulp, paper, or paperboard and are located at a plant site that is a major source. Voith is not a major source; therefore, the facility is not subject to this subpart.

40 CFR Part 63, Subpart JJJJ—National Emission Standards for Hazardous Air for Paper and Other Web Coating: This subpart is applicable to facilities that operate web coating lines and are a major source. Voith is not a major source; therefore, the facility is not subject to this subpart.

40 CFR Part 63, Subpart OOOO—National Emission Standards for Hazardous Air for Printing, Coating, and Dyeing of Fabric and Other Textiles: This subpart is applicable to facilities that are involved in the printing, coating, slashing, dyeing, or finishing of fabric and other textiles and are a major source of HAPs. Voith is not a major source; therefore, the facility is not subject to the requirements of Subpart OOOO.

PUBLIC PARTICIPATION

Because this facility is a true minor source of all criteria pollutants and hazardous air pollutants, no public notice period will be required for this permitting action.
