NACT 246 Aggregate, Asphalt, and Concrete Batching Operations | January 24-25, 2022 | AGENDA
Course Description: 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.

NACT 252 Fugitive Dust | January 26, 2022 | AGENDA
Learning Objectives: After completion of this one-day course, learners will be able to explain fugitive dust control in the context of the following topics:

  • Health Effects of PM10 Pollution
  • Fugitive Dust Sources
  • Dust Control Measures
  • Fugitive Dust Rules & Regulations
  • Dust Control Plans
  • Visible Dust Emissions and Test Methods

NACT 273 Industrial Boilers | January 27, 2022 | AGENDA
Course Description: Boilers are one of the most common emission sources and range in use from small fire tube boilers to large utility boilers associated with power plant facilities. The course discusses uses of boilers, heat transfer methods and fundamentals of operation of modern industrial and utility boilers including those fired by natural gas, biomass, municipal waste and coal (circulating fluidized bed units). The course also discusses steam turbines and power generation. This is followed by a detailed discussion on emissions and control techniques such as Low-NOx burners, FGR, staged combustion, SCR and SNCR. New technologies such as Ultra Low-NOx 9 ppm burners, applicable federal and local BACT regulations, permitting requirements and agency inspection procedures and safety concerns are thoroughly discussed.

Registration Instructions: This training series will be held via EPA’s new Learning Management System (LMS) and WebEx. There is NO registration fee for state and local employees attending this training.
