Hot Mix Asphalt Plants: Control Facilities Required
(1)
No person may operate any hot mix asphalt plant, either portable or stationary, located within any area of the state outside special control areas unless all dusts and gaseous effluents generated by the hot mix asphalt plant are controlled by a control device or devices with a removal efficiency for particulate matter of at least 80 percent by weight. To determine compliance with this standard, the owner or operator must conduct a particulate matter source test using DEQ Method 5 at the inlet and outlet of the control device. If it is not feasible to conduct a particulate matter source test at the inlet to the control device, the owner or operator must provide documentation demonstrating that the control device is designed to meet the standard and prepare and implement an operation and maintenance plan for ensuring that the control device will have at least an 80 percent removal efficiency when operated.(2)
No person may operate any hot mix asphalt plant, either portable or stationary, located within any special control area of the state without installing and operating systems or processes for the control of particulate emissions so as to comply with the emission limits established by the process weight table, OAR 340-236-8010 (Solid Waste Landfills: Table-Process Weight Table), attached herewith and by reference made a part of this rule. Compliance is determined using DEQ Method 5. All source tests must be done using the DEQ Source Sampling Manual.(3)
Hot mix asphalt plants are subject to the emission limitations in OAR 340-208-0110 (Visible Air Contaminant Limitations)(1), 340-226-0210 (Grain Loading Standards: Particulate Emission Limitations for Sources Other Than Fuel Burning Equipment, Refuse Burning Equipment and Fugitive Emissions), and 340-238-0060 (Federal Regulations Adopted by Reference), as applicable.(4)
If requested by DEQ, the owner or operator must develop a fugitive emission control plan.
