Clean air act & air permits in California
Energy Systems specializes in permitting emergency standby and prime power engines as per Clean Air Act Permitting in California, and can assist with all phases of the air permitting process, including but not limited to:
To achieve the objectives of the federal Clean Air Act (CAA), the United States Environmental Protection Agency (USEPA) has established permitting programs through its regional offices. USEPA has delegated authority over air permitting in California to the California Air Resources Board (CARB). Air permitting in California is administered at a local level through 35 individual air districts, that enforce federal and state regulations, as well as implement their own unique regulations, permitting policies, and procedures. As a result, air permitting covers a combination of federal, state, and local rules and regulations, as well as source-specific requirements.
Local air districts may impose more stringent requirements than the federal and state regulations, but they cannot have lesser requirements. Air quality permitting and emissions requirements vary by air district due to region-specific air quality issues (attainment status), as well as economic and environmental factors.
Obtaining air quality permits is often a complex and lengthy process, and permitting requirements are continuously updated on a local level. We are experts at the implementation of Clean Air Act in California air permitting and compliance, and ensure that you will receive the most up-to-date guidance on permitting requirements specific to your project. With our extensive knowledge, Energy Systems can prepare and submit complete and accurate air permit applications, which streamlines the permitting process and helps secure the air permit for your project in a timely manner.
CARB requires stationary generator engines rated 50 brake-horsepower (bhp) (equivalent to 37 kW) or greater to obtain an air quality permit issued by the local air district. A limited few air districts have permitting exemptions based on specific criteria (limited operational hours, fuel type, etc.). Any new or modified sources are required to obtain a permit. This includes replacement or modified generator engines. Generator engines that are moved to a new facility are also required to obtain an air permit.
Portable generator engines require equipment registration through the CARB Portable Equipment Registration Program (PERP). The Energy Systems can assist with PERP registration through our Rental Department.
There are typically two parts to an engine air permit, which include:
CARB’s Air Toxics Control Measure for Stationary Compression-Ignition Engines (ATCM) sets forth the emissions standards and operational requirements for stationary generator diesel engines at the state level. Most air districts follow the state’s ATCM emissions standards, which require stationary diesel engines comply with the following:
Due to the need to reduce regional diesel engine emissions, several air districts are now requiring Tier 4F certification or compliance for engines rated 1,000 bhp or greater, including:
Other air districts are currently considering changes to their emissions requirements:
Energy Systems can provide information and guidance on the latest regulatory developments to ensure that your generator equipment can secure an air quality permit according to the Clean Air Act and air permitting in California. We are also able to provide Tier 4F solutions and emissions controls technology evaluations to help you determine the best solution for your project.
Energy Systems is a leading distributor of Generac power and industrial generator systems, along with custom home and commercial solutions with an excellent reputation in the industry for exceptional sales, service, training and rentals.
