The Small Business Environmental Assistance Program has developed a series of Microsoft Excel spreadsheets to help small businesses determine if they need an air permit and to track emissions as required by their current air permits. Some spreadsheets will require customization to better represent the products and processes at individual facilities.
Abrasive blasting. Determine potential and actual emissions for blasting activities.
Aggregate, non-metallic mineral processing. Determine potential and actual emissions at sand and gravel operations using the air emissions calculator. Maintain compliance records with the non-metallic mineral processing general air permit and with the compliance calendar.
Asphalt. Determine potential and actual emissions from hot mix asphalt plants.
Boilers. Determine potential and actual emissions for natural gas, fuel oil, propane, coal, and wood-fired boilers.
Coating and auto body facilities. Determine potential and actual emissions for coating and auto body facilities. Also determine whether the facility qualifies as a conditionally exempt source under Minn. R. 7008.2300.
Coatings/painting. Determine potential and actual air emissions from painting and coating operations. Also determine whether the facility qualifies as a conditionally exempt source under Minn. R. 7008.2400.
Engines (generators). Determine potential and actual emissions from diesel and gasoline engines and natural gas turbines.
Grain elevators and feed mills. Determine potential and actual air emissions from grain elevators or feed mills.
Hazardous air pollutants and air toxics. Search for hazardous air pollutants and other air toxics by name or CAS number.
Insignificant facility. Determine eligibility as an insignificant facility under Minn. R. 7008.2600.
Mechanical finishing. Determine potential and actual emissions from mechanical finishing. Also determine whether the facility's activities qualify as conditionally insignificant under Minn. R. 7008.4110.
Option C registration permit. Determine permit eligibility and helps maintain compliance records.
Option D registration permit. Calculate and track 12-month rolling sums.
Storage tanks. Determine potential and actual air emissions for various storage tanks.
Vapor recovery, gasoline. Estimate emission reductions from installing stage 1 vapor recovery on underground gasoline storage tanks.
Woodworking facility. Determine whether the facility qualifies as a conditionally exempt source under Minn. R. 7008.2500.
