Air Pollution Regulatory Compliance Assistance

Small businesses may not have staff members prepared to handle the requirements stipulated in air permits; therefore, many of the businesspeople who seek assistance either own or work for small businesses. Missouri statutes define a small business as having one or more of the following attributes:

• Employs less than 100 people
• Emits less than 50 tons of any regulated pollutant per year or less than 75 tons of all regulated pollutants
• Does not have the potential to emit 10 tons per year of any hazardous air pollutant
• Does not have the potential to emit 25 tons of any combination of hazardous air pollutants
• Does not have the potential to emit 100 tons per year of an air contaminant with or without control devices
• Meets other definitions as defined by the Missouri Air Conservation Commission
