Update Summary Facilities

A facility determined to be intermediate priority or intermediate risk by the District are exempt from the requirements of AB 2588 for a period of four years. Every four years this exemption will be re-evaluated through the District’s Update Summary process. Factors that may require a facility to be reinstated in the AB 2588 program are identified in CARB’s Emission Inventory Criteria and Guidelines for the Air Toxics “Hot Spots” Program (EICG) Section V.H and include, but are not limited to, the following:

Increases in throughput, fuel usage, process rate changes, or emissions;
changes in types of fuels or substances used at the facility;
determinations that previous source test data are inadequate;
addition of new processes or equipment to the facility which cause increases in emissions;
issuance of new permits or changes in permit conditions;
emissions of new air toxics;
reductions in the distance from the facility to the nearest receptor;
changes in emission factors;
changes in methodologies, such as emission quantification methods, dispersion modeling methods, risk assessment methods, and other hazard evaluation methods;
other factors the district considers relevant.

The District will notify facilities when they need to be re-evaluated through the annual emission inventory. Facilities must complete and return a special survey included with the annual emission inventory to determine if they are still exempt from the requirements of AB 2588 or must be reinstated.
