OAR 340-228-0210
General Emission Standards for Fuel Burning Equipment: Grain Loading Standards


(1)

This rule applies to fuel burning equipment, except solid fuel burning devices that have been certified under OAR 340-262-0500 (Certification of Solid Fuel Burning Devices for Sale as New).

(2)

No person may cause, suffer, allow, or permit particulate matter emissions from any fuel burning equipment 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 until Dec. 31, 2019; and
(ii)
0.15 grains per dry standard cubic foot on and after Jan. 1, 2020; and

(C)

In addition to the limits in paragraph (A) or (B), for equipment or a mode of operation (e.g., backup fuel) 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 and 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 collected prior to April 16, 2019 demonstrate emissions 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 on or after April 16, 2015, 0.10 grains per dry standard cubic foot.

(d)

Intentionally left blank —Ed.

(A)

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 set a source specific limit of 0.17 grains per dry standard cubic foot. The owner or operator must submit an application for a permit modification to request the alternative limit by no later than Oct. 1, 2019 that demonstrates, based on a signed report prepared by a registered professional engineer that specializes in boiler/multiclone operation, that the fuel burning equipment will be unable to comply with the standard in subparagraph (a)(B)(ii) after either:
(i)
Maintenance or upgrades to an existing multiclone system; or
(ii)
Conducting a boiler tune-up if the boiler does not have a particulate matter emission control system.

(B)

If a source qualifies under paragraph (A), DEQ will add the 0.17 grains per dry standard cubic foot source specific limit as a significant permit modification (simple fee) for sources with an Oregon Title V Operating Permit or a Simple Technical Modification for sources with an Air Contaminant Discharge Permit.

(e)

The owner or operator of a source installed, constructed or modified before June 1, 1970 may request that DEQ grant an extension allowing the source up to one additional year to comply with the standard in paragraph (d)(A) provided that the owner or operator demonstrates, based on an engineering report signed by a registered professional engineer that specializes in boiler/multiclone operation, that the source cannot comply with the source specific limit established in OAR 340-228-0210 (General Emission Standards for Fuel Burning Equipment: Grain Loading Standards)(2)(d)(A) without making significant changes to the equipment or control equipment or adding control equipment. 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 Oregon Method 5, or an alternative method approved by DEQ. [NOTE: Sampling methods are found in the DEQ Source Sampling Manual published with OAR 340-200-0035 (Reference Materials).]

(a)

For fuel burning equipment that burns wood fuel by itself or in combination with any other fuel, the emission results are corrected to 12% CO2.

(b)

For fuel burning equipment that burns fuels other than wood, the emission results are corrected to 50% excess air.

(c)

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 fuel burning equipment 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 (State of Oregon Clean Air Act Implementation Plan).
