Control Facilities Required
(1) No person shall operate any hot mix asphalt plant, either portable or stationary, located within any area of the state unless all dusts and gaseous effluents generated by the drum or batch unit are subjected to a particulate emissions control device or devices with a rated control efficiency of at least 80 percent by weight.
(2) No person shall 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, Table 1, attached herewith and by reference made a part of this rule.
(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, that will prevent any visible emissions from leaving the property of a source for more than six minutes in any hour. Visible emissions are determined by EPA Method 22 at the downwind property boundary.
(5) Compliance with the emissions standard in sections (1) and (2) is determined using DEQ Method 5. All source tests shall be done in accordance with DEQ’s Source Sampling Manual (March 2014).

Other Established Air Quality Limitations
The emission limits established under OAR 340-236-0400 through 340-236-0440 are in addition to visible emission and other ambient air standards, established or to be established by the Environmental Quality Commission unless otherwise provided by rule or regulation.

Portable Hot Mix Asphalt Plants
Portable hot mix asphalt plants may apply for air contaminant discharge permits within the area of Department jurisdiction without indicating specific site locations. As a condition of said permit, the permittee will be required to obtain approval from DEQ for the air pollution controls to be installed at each site location or set-up at least ten days prior to operating at each site location or set-up.

Ancillary Sources of Emission -- Housekeeping of Plant Facilities
(1) Ancillary air contamination sources from the plant and its facilities which emit air contaminants into the atmosphere such as, but not limited to, the drier openings, screening and classifying system, hot rock elevator, bins, hoppers, and pug mill mixer, shall be controlled at all times so as to maintain the highest possible level of air quality and the lowest possible discharge of air contaminants.
(2) The handling of aggregate and traffic shall be conducted at all times so as to minimize emissions into the atmosphere.

Limit to drum or batch because you can’t capture all the dust from the whole plant
jill inahara, 2013-03-07T13:16:00Z
How do you show compliance with this limit?
pcuser, 2013-03-07T13:16:00Z
Rated efficiency – can get this number from the manufacturer. Source test not required.
jill inahara, 2013-03-07T13:16:00Z
Should we combine (1) and (2) for all areas of the state? Grunow??
