Internal Combustion (IC) engines generate power by burning liquid fuel (e.g. by burning diesel, gasoline, LPG, natural gas, or waste gas). IC engines are found in a variety of industries and can be used for generating electrical power, pumping gas or other fluids, or compressing air for pneumatic machinery. IC engines generate emissions by the combustion of fuel. These emissions are regulated by the Sac Metro Air District.
Who Needs a Permit?
A permit is required for all IC Engines with a maximum rating greater than 50 brake-horsepower.
Engines with a rating of 50 brake-horsepower or less may not be exempt if they are part of a process (e.g. rock screening plant, or a concrete batch plant) that requires a permit from the District. In that case, the engine will be permitted as part of the overall process and will not require a separate permit.
Portable engines with valid CARB PERP registration are not required to obtain a permit from the Sac Metro Air District provided the owner/operator is complying with all the requirements of the PERP registration and the engine is not operating as part of a stationary source as determined by Sac Metro Air District.
Agricultural engines may be required to obtain a permit or registration. For more information click here.
