Or. Admin. R. 340-236-0410 - 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, 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(1), 340-226-0210, and 340-238-0060, as applicable.
(4) If requested by DEQ, the owner or operator must develop a fugitive emission control plan.

[NOTE: This rule is included in the State of Oregon Clean Air Act Implementation Plan that EQC adopted under OAR 340-200-0040.]

[NOTE: DEQ Method 5 is contained in the DEQ Source Sampling Manual published with OAR 340-200-0035.]
