Registration for Agricultural Diesel Engines

Owners or operators of stationary compression ignition (diesel) engines used in agricultural operations within the Air District's jurisdiction are subject to Regulation 11, Rule 17 and must register their agricultural equipment with the Air District per Section 11-17-401.

In 1998, the California Air Resources Board identified diesel particulate matter as a toxic air contaminant. In order to reduce the public’s exposure to diesel PM, CARB has approved a number of regulatory measures affecting the vast majority of diesel engines operating in California. The Air District and other local air quality agencies throughout California are required to implement these “Airborne Toxic Control Measures,” or ATCMs.

The ATCM for Stationary Compression Ignition Engines (Sections 93115 through 93115.15, Title 17, of the California Code of Regulations) includes requirements for diesel-fueled engines used in agricultural operations.

You are required to keep your stationary agricultural diesel engine registration current as long as you operate your equipment.

Online Permitting System
Eligible facilities can log in to apply for new registrations and renewals on the Air District's online permitting system web page.

Renewal

The previous stationary agricultural diesel engine registration system went offline in 2016. The Air District will issue new renewal invoices to all facilities that had active registrations for stationary agricultural diesel engines at that time. To renew a stationary agricultural diesel engine registration which expired prior to 2016, please contact the Online Permitting System Help Desk.

Future renewal invoices will be sent out annually, typically 30 to 60 days before expiration.

Fees

The registration fees are set forth in Regulation 3, Schedule R. Both initial registration fee and annual renewal fee are for each engine. The Alternative Compliance Plan fee is for each plan submitted under Air District Regulation 11, Rule 17, Section 402. You will be invoiced for the annual renewal fees prior to the expiration of the registration.

Late registrations will incur a back fee equal to the annual renewal fees prorated from the effective date of registration requirements, up to a maximum of five years.
