Truck Dump and Storage Areas:(a)
Every person operating or intending to operate a particleboard manufacturing plant must enclose truck dump and storage areas holding or intended to hold raw materials to prevent windblown particle emissions from these areas from being deposited upon property not under the ownership of said person;(b)
The temporary storage of raw materials outside the regularly used areas of the plant site is prohibited unless the person who desires to temporarily store such raw materials first notifies DEQ and receives written approval for said storage:(A)
When authorized by DEQ, temporary storage areas must be operated to prevent windblown particulate emissions from being deposited upon property not under the ownership of the person storing the raw materials;(B)
Any temporary storage areas authorized by DEQ may not be operated in excess of six (6) months from the date they are first authorized.(c)
Any person who proposes to control windblown particulate emissions from truck dump storage areas other than by enclosure must apply to DEQ for written authorization to utilize alternative controls. The application must describe in detail the plan proposed to control windblown particulate emissions and indicate on a plot plan the nearest location of property not under ownership of the applicant.(2)
Other Emission Sources:(a)
The combined particulate emissions from particleboard plant sources including, but not limited to, hogs, chippers, and other material size reduction equipment, process or space ventilation systems, particle dryers, classifiers, presses, sanding machines, and materials handling systems must not exceed a plant specific average hourly emission rate, pounds per hour, determined by multiplying the plant production capacity by three pounds per 1000 square feet. The plant production capacity is the maximum production in terms of 1,000 square feet on a 3⁄4 inch basis of finished product for a typical operating shift divided by the number of hours in the operating shift.(b)
Excepted from subsection (2)(a) are truck dump and storage areas, fuel burning equipment, and refuse burning equipment.(c)
Compliance with the average hourly emission rate is determined by summing the emissions from the affected sources as determined by emission factor calculations or actual emissions data for a 24 hour period divided by 24.
