  1. What is the purpose of this permit?  This permit authorizes construction of a second Regenerative Thermal Oxidizer (RTO-2) to control finishing line emissions of Volatile Organic Compounds (VOC), Hazardous Air Pollutants (HAP), and Toxic Air Contaminants (TAC). Currently the finishing line is controlled by combustion in one RTO and two coal-fired boilers. The coal-fired boilers are scheduled to be removed and this new RTO will serve as additional control for the finishing line. Both RTOs will be operated at the same time. If there are operational issues or maintenance needs to be performed on either, the other will be able to provide high efficiency control of process emissions. 

  2. Will this permit increase pollution? Construction Permit C-0011-22-0036-V will not increase pollution. 

  3. Does this facility have a history of non-compliance?  The District issued a notice of violation on April 26, 2023, alleging exceedances of standards for their  spray reactor and coal-fired boilers. A draft Agreed Board Order to resolve the alleged violation has been proposed and is available for public comment Prior to that, the District, company, and Air Pollution Control Board entered into an agreed board order to resolve an alleged violation related to exceedances of the company’s Environmental Acceptability Demonstration (EA Demo). See the Compliance History Section of the Statement of Basis.
