Regulated Business

The Benton Clean Air Agency is responsible for regulating air emissions from stationary commercial facilities as well as portable sources.

Source Registration

There are about 180 facilities registered with Benton Clean Air per BCAA Regulation 1, which lists sources identified as having potentially significant air emissions and therefore required to be in the agency’s Registration Program.

The Registration program is described in the Washington Administrative Code 173-400-99 and Source Classifications are listed in 173-400-100

New Source Review (NSR)

Additionally, these facilities may need to undergo a Notice of Construction (NOC) approval process prior to any modification of existing equipment or installation of new equipment.

The NSR program is described in the Washington Administrative Code 173-400-110
