OAR 340-240-0350
La Grande Urban Growth Area: Air Conveying Systems

(1)

No person is allowed to cause or permit the emission of particulate matter in excess of 0.10 grains per standard cubic foot from any air conveying system emitting less than or equal to ten tons of particulate matter to the atmosphere during any 12-month period beginning on or after January 1, 1990 except as allowed by section (2).

(2)

The owner or operator of an existing source who is unable to comply with OAR 340-226-0210 (Grain Loading Standards: Particulate Emission Limitations for Sources Other Than Fuel Burning Equipment, Refuse Burning Equipment and Fugitive Emissions)(1)(a)(B) or (b)(C) may request that DEQ grant an extension allowing the source up to one year to comply with the standard, and DEQ may grant such extension if it determines that such period is necessary for the installation of controls.

(3)

All air conveying systems emitting greater than 10 tons of particulate matter to the atmosphere during any 12-month period beginning on or after January 1, 1990 must be equipped with a particulate emissions control device or devices with a rated control efficiency of at least 98.5 percent .

(4)

No person may cause or permit the emission of any air contaminant which is equal to or greater than five percent opacity as a six minute average from any air conveying system subject to section (3).
NOTE: These rules are included in the State of Oregon Clean Air Act Implementation Plan that EQC adopted under OAR 340-200-0040 (State of Oregon Clean Air Act Implementation Plan).
