Or. Admin. Code § 340-226-0210 - Grain Loading Standards: Particulate Emission Limitations for Sources Other Than Fuel Burning Equipment, Refuse Burning Equipment and Fugitive Emissions

(1) This rule does not apply to fugitive emissions sources, fuel burning equipment, refuse burning equipment, or to solid fuel burning devices certified under OAR 340-262-0500.

(2) No person may cause, suffer, allow, or permit particulate matter emissions from any air contaminant source in excess of the following limits:

(a) For sources installed, constructed, or modified before June 1, 1970:

(A) 0.10 grains per dry standard cubic foot provided that all representative compliance source test results collected prior to April 16, 2015, demonstrate emissions no greater than 0.080 grains per dry standard cubic foot;

(B) If any representative compliance source test results collected prior to April 16, 2015 demonstrate emissions greater than 0.080 grains per dry standard cubic foot, or if there are no representative compliance source test results, then:

(i) 0.24 grains per dry standard cubic foot prior to Dec. 31, 2019; and

(ii) 0.15 grains per dry standard cubic foot on or after Jan. 1, 2020; and

(C) In addition to the limits in paragraphs (A) or (B), for equipment or a mode of operation that is used less than 876 hours per calendar year, 0.24 grains per dry standard cubic foot from April 16, 2015 through December 31, 2019, and 0.20 grains per dry standard cubic foot on or after Jan. 1, 2020.

(b) For sources installed, constructed, or modified on or after June 1, 1970 but prior to April 16, 2015:

(A) 0.10 grains per dry standard cubic foot provided that all representative compliance source test results prior to April 16, 2015 demonstrate emissions no greater than 0.080 grains per dry standard cubic foot; or;

(B) If any representative compliance source test results prior to April 16, 2015 are greater than 0.080 grains per dry standard cubic foot, or if there are no representative compliance source test results, then 0.14 grains per dry standard cubic foot.

(c) For sources installed, constructed or modified after April 16, 2015, 0.10 grains per dry standard cubic foot.

(d) The owner or operator of a source installed, constructed, or modified before June 1, 1970 who is unable to comply with the standard in subparagraph (a)(B)(ii) may request that DEQ grant an extension allowing the source up to one additional year to comply with the standard. The request for an extension must be submitted no later than Oct. 1, 2019.

(3) Compliance with the emissions standards in section (2) is determined using:

(a) Oregon Method 5;

(b) DEQ Method 8, as approved by DEQ for sources with exhaust gases at or near ambient conditions;

(c) DEQ Method 7 for direct heat transfer sources [NOTE: DEQ Methods are described in the DEQ Source Sampling Manual published with OAR 340-200-0035] ; or

(d) An alternative method approved by DEQ.

(e) For purposes of this rule, representative compliance source test results are data that was obtained:

(A) No more than ten years before April 16, 2015; and

(B) When a source is operating and maintaining air pollution control devices and emission reduction processes at the highest reasonable efficiency and effectiveness to minimize emissions based on the current configuration of the emissions unit and pollution control equipment.

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