When an NSR permit is issued, the standard required is normally determined by a state or local agency on a case-by-case basis. A BACT is the standard required for locations that are considered attainment areas. RACTs are reserved for modifications to facilities in non-attainments locations. LACT is mandatory for new or modified facilities in non-attainment locations.
How Are BACT Guidelines Met?
Guidelines are used to determine if the proposed control systems meets BACT. The appropriate control level is based on:
These factors are used after other review requirements have been met. Small sources and those with existing quality emissions control systems have a reduced need for full analysis.
The Texas Commission on Environmental Quality (TCEQ) provides a set of guidelines for determining the BACT for a variety of sources. For example, in chemical processing, basic or acidic gases and soluble hydrocarbon is subject to a minimum of 99 percent recovery.
The BACT for dry bulk fertilizer handling controls are normally achievable through a baghouse or choke feeding. In mechanical transfers, the minimum control is an enclosed conveyor or similar method. All mixing must be performed in an enclosure.
