The NACT 200 Series training courses (outlined below) are intended for new, entry-level as well as semi-experienced staff.


NACT 231 Surface Coating: Metal Parts & Products

Instructor: Bob Waterfall


Site Visit: This class will include a field trip at a local automobile or metal parts and products coating operation where topics discussed in class will be observed in practical application. Details to follow.

COURSE OBJECTIVES: This one-day course covers the history and applications of surface coatings for both automobiles and metal parts and products. Topics to be covered include a brief history of coatings technology development (and their impacts on air pollution), coating formulation and structure, coating uses, and methods of controlling emissions from coating application such as enclosed spray booths, High Volume Low Pressure (HVLP) spray systems, fluid impingement spray technology (FIT) and good work practices. Students will be introduced to permitting considerations such as Federal NESHAP requirements, Best Available Control Technology discussion, as well as inspection techniques and methods of determining compliance.


NACT 233 Solvent Cleaning: Degreasing Operations

Instructor: Bob Waterfall


Site Visit: Students will also receive first-hand experience during the afternoon field visit (mock inspection) at a local business with a permitted solvent cleaning operation. Details to follow.

COURSE OBJECTIVES: This one-day course provides baseline information on a variety of solvents cleaning/degreasing operations. Topics include: types of solvents, types of degreasers, emission control equipment used and inspection procedures. Discussion of regulatory issues such as the Title III MACT standards, NESHAPS for Halogenated Solvents, RACT/BACT guidelines and local prohibitory rules are also included.


NACT 246 Aggregate, Asphalt, and Concrete Batching Operations (and HMA)

Instructor: Steve Frey


Site Visit: 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. Details to follow.

COURSE OBJECTIVES: 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. This course will provide an overview and discussion of applicable New Source Performance Standards, 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.
