Rule 4702 controls emissions from internal combustion (IC) engines rated at 25 bhp or greater used in the Valley at facilities such as, but not limited to, oil and gas production facilities, agricultural operations, petroleum refineries, and water districts. Under Rule 4702, IC engine operators are required to submit the number of engines at the stationary source, perform extensive monitoring and record keeping through the implementation of an Inspection and Monitoring plan, submit an Emission Control Plan, and meet emission limits/standards and compliance schedules.
Through commitments from the District’s 2018 PM2.5 Plan, the District is exploring potential amendments to Rule 4702 to further reduce NOx emissions from this source category. Given the need for additional reductions to meet the latest health-based federal air quality standards, the District has begun a regulatory amendment process in exploring potential opportunities to achieve additional NOx emissions reductions from IC engines to the extent that such controls are technologically and economically feasible. As a part of the District’s expedited Best Available Retrofit Control Technology (BARCT) review schedule, this rule development effort will also include an evaluation of feasible VOC emission limits for IC engines.
