Volkswagen Group of America, Inc., Chattanooga Operations LLC, has requested a revision to its Best Available Control Technology (BACT) emission limitation for emissions of nitrogen oxides (NOx) at its Chattanooga facility, officials of the Chattanooga-Hamilton County Air Pollution Bureau said.

The facility at the Enterprise South Industrial Park is seeking a plant-wide 20% increase in NOx emissions, which includes emissions from its natural gas-fueled thermal oxidizers used to control volatile organic compound emissions from the facility paint shop.

The Chattanooga-Hamilton County Air Pollution Control Bureau director has made a preliminary determination that the requested new limits should be incorporated into a PSD permit modification and would be in line with limits set for thermal oxidizers at similar automobile assembly plants, it was stated.

The Chattanooga-Hamilton County Air Pollution Control Board will receive public comments upon that and other permit requests on Monday, Dec. 3, at 5 p.m. in Room 1-A, Development Resource Center, 1250 Market St.

The purpose of this hearing is "to receive public comments concerning air pollution sources located within Hamilton County, Tennessee."

Also, ADM Sweetener Terminal, 5991 Hickory Valley Road, which operates a bulk sugar transfer facility, has made application for federally enforceable certificates of operation for four existing sugar transfer sysems.

ADM Southern Cellulose Products, Inc., 103 West 45th St., which produces cellulose pulp from cotton linters, has made application for a federally enforceable certificate of operation for existing paper machine heaters as part of its plant-wide limit on greenhouse gas emissions.

NA Industries, Inc. 2651 Riverport Road, which operates a specialty polymers production facility has made application for a federally enforceable certificate of operation to replace its current Part 70 permit. In addition, NA Industries, Inc. has made application to restart a polymers production line taken out of service earlier in 2012 and reinstate operation of three boilers supplying steam to that line in order to replace lost production capacity at another facility owned by the company. That application does not require federally enforceability status or public hearing, it was stated.

The draft permits, applications, and all relevant supporting materials will be available for review at the permitting authority, the Chattanooga-Hamilton County Air Pollution Control Bureau, 6125 Preservation Drive, Chattanooga, Tennessee, beginning Thursday from 8 a.m. to 4:30 p.m. on weekdays or online
