NACT 290 (Tuesday, June 12, 2018)MACT General Background Information

This one day course is designed to provide general background information on (1) various ARB and EPA toxic regulations/programs: MACTs and ATCMs, ARB Hot Spots vs EPA Significant Risk Programs, EPA and California Accidental Release Prevention Programs; (2) listing of toxic air contaminants and hazardous air pollutants, and of EPA's toxic source categories; (3) pathways for ARB and EPA enforcement; and (4) lowering a source's potential to emit (for MACT sources).


NACT 246 (Wednesday and Thursday, June 13-14, 2018Aggregate, Asphalt, & Concrete Batching Operations

This two-day course is aimed at new, entry-level as well as semi-experienced stationary source permit engineers, inspectors, regulatory agency staff, and environmental specialists in business and government. This course will provide an overview and discussion of the processes commonly seen at sand and gravel operations, concrete batching operations, and hot mix asphalt (HMA) operations. Processes such as quarrying, sizing of quarried material, sorting, stockpiling, and transfer of aggregate products will be discussed in the aggregate section of this class. Concrete batching issues such as dust abatement and the flow of aggregate and cement materials will also be discussed. Hot mix asphalt operations also have many similar processes, and we will discuss the similarities with aggregate and concrete batching operations, including aggregate handling, storage, transfer, processing, and more. Additionally, we will also explore some of the issues that are particular to HMA facilities such as “blue smoke” controls which can include baghouse filters and capture/incineration of blue smoke mist. Combustion controls such as low-NOx burners will also be discussed as they pertain to HMA and aggregate operations. This course includes a field trip to a local aggregate/concrete/HMA facility to observe the process in-person, and affords an opportunity for students to interact with facility operators.



Registration will be handled through APTI-Learn at  Please remember to register for each NACT course individually.
