  § 10-108. Process equipment or operations.  

Latest version.

  • (a)

    Dust control. The owner or operator of any process equipment or operation shall maintain dust control of the plant premises and of the access roads of the plant by paving, by oil treatment or by other suitable measures. (food operating practices shall be observed in relation to stockpiling, screen changing, and general maintenance to prevent dust generation and atmospheric entrainment. Good operating practices, including water spraying or other suitable measures, shall be employed to minimize dust generation and emission when bins are pulled.

    (b)

    Particulate matter emission. Process equipment or op- erations shall not emit, from the premises upon which such equipment or operation is located, particulate matter in excess of that indicated in the following chart:

    (c)

    Interpolation of the data in this chart for process weight rates up to 60,000 lb/hr shall be accomplished by use of the equation E = 4.10 P 0.67 , and interpolation and extrapolation of the data for process weight rates in excess of 60,000 lb/hr shall be accomplished by use of the equation E = 55.0 P 0.11 - 40 where E = rate of emission in lb/hr and P = process weight rate in tons/hr.

    (d)

    Utilization of this table is accomplished by first determining the process rate in Lb/Hr or in Tons/Hr and then reading the allowable rate of emission in Lb/Hr horizontally to the right.
