Approximately 51 lightweight aggregate manufacturing plants operate in the United States. Table 2-1 lists the States in which lightweight aggregate manufacturing plants are located. Domestic production of lightweight aggregate in 1990 totaled 3,800,000 Megagrams (Mg) (4,200,000 tons) and was valued at $26 million.

That is to say, the construction project is viewed as consisting of several operations, each involving traffic and material movements, and emission factors from other AP-42 sections are used to generate estimates. Table 13.2.3-1 displays the dust sources involved with construction, along with the recommended emission factors.3.
