Opacity-Grain Loading Rule Language for FISCAL Uri-Mark

(1) The emissions standards in this rule do not apply to fugitive emission sources.

(2) The visible emissions standards in this rule are based on a 6-minute average as measured by:

(a) EPA Method 9,

(b) a continuous opacity monitoring system (COMS) installed and operated in accordance with the DEQ Continuous Monitoring Manual or 40 CFR Part 60; or

(3) For emission sources, other than wood-fired boilers, that existed prior to June 1, 1970 and have not been modified since May 31, 1970:

(a) If located outside a special control area, visible emissions must not equal or exceed:

(A) 40% opacity through December 31, 2019; and

(B) 20% opacity on and after January 1, 2020

(b) If located inside a special control area, visible emissions must not equal or exceed 20% opacity.

(5) For wood-fired boilers that existed prior to June 1, 1970 and have not been modified since May 31, 1970, visible emissions must not equal or exceed:

(a) 40% opacity through December 31, 2019 with the exception that emissions may not equal or exceed 55% opacity for 12 minutes in an hour, as the average of two 6-minute Method 9 observation periods.

(b) 20% opacity on or after January 1, 2020, with the exception that:

(A) emissions may not equal or exceed 40% opacity for 12 minutes in an hour, as the average of two 6-minute Method 9 observation periods; and

(B) Emissions may not equal or exceed 40% opacity, as the average of all 6-minute Method 9 observation periods during grate cleaning operations provided the grate cleaning is performed in accordance with a grate cleaning plan approved by DEQ.

(6) For wood-fired boilers installed, constructed, or modified after June 1, 1970 but before November 1, 2014, visible emissions must not equal or exceed 20% opacity with the exception that emissions may not equal or exceed 40% opacity for 12 minutes in an hour, as the average of two 6-minute Method 9 observation periods.

(7) For all wood-fired boilers installed, constructed, or modified after November 1, 2014, emissions must not equal or exceed 20% opacity.

(8) By no later than January 1, 2020, all wood-fired boiler emission stacks must have a continuous opacity monitoring system (COMS) installed, certified, maintained, and operated in accordance with DEQ’s continuous monitoring manual or 40 CFR Part 60.

(1) This rule does not apply to fugitive emission sources, indirect heat transfer fuel burning equipment, refuse burning equipment, and solid fuel burning devices that have been certified under OAR 340-262-0500.

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

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

(A) 0.10 grains per dry standard cubic foot unless representative compliance source test data prior to November 1, 2014 is greater than 0.080 grains per dry standard cubic foot;

(B) 0.2 grains per dry standard cubic foot through December 31, 2019;

(D) For equipment or a mode of operation (e.g., backup fuel) that is used less than 876 hours per calendar year, 0.20 grains per standard cubic foot beginning January 1, 2020.

(b) For sources installed, constructed, or modified on or after June 1, 1970 but prior to November 1, 2014:

(A) 0.10 grains per dry standard cubic foot unless representative compliance source test data prior to November 1, 2014 is greater than 0.080 grains per dry standard cubic foot;

(B) 0.1 grains per dry standard cubic foot through December 31, 2019; or

(d) The owner or operator of a source installed, constructed or modified before November 1, 2014 who is unable to comply with the compliance dates specified in paragraphs (a)(C) and (b)(C) 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 October 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;

(d) An alternative method approved by DEQ.

Grain Loading Standards

(1) This rule applies to indirect heat transfer fuel burning equipment, except solid fuel burning devices that have been certified under OAR 340-262-0500.

(2) No person may cause, suffer, allow, or permit particulate matter emission from any indirect heat transfer fuel burning equipment in excess of:

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

(A) 0.10 grains per dry standard cubic foot unless representative compliance source test data prior to November 1, 2014 is greater than 0.080 grains per dry standard cubic foot;

(B) 0.2 grains per dry standard cubic foot through December 31, 2019;

(D) For equipment or a mode of operation (e.g., backup fuel) that is used less than 876 hours per calendar year, 0.20 grains per standard cubic foot beginning January 1, 2020.

(b) For sources installed, constructed, or modified on or after June 1, 1970 but prior to November 1, 2014:

(A) 0.10 grains per dry standard cubic foot unless representative compliance source test data prior to November 1, 2014 is greater than 0.080 grains per dry standard cubic foot;

(B) 0.1 grains per dry standard cubic foot through December 31, 2019;

(d) The owner or operator of a source installed, constructed or modified before November 1, 2014 who is unable to comply with the compliance dates specified in paragraphs (a)(C) or (b)(C) 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 October 1, 2019.

(3) Compliance with the emissions standards in section (2) is determined using Oregon Method 5, or an alternative method approved by DEQ.

(a) For indirect heat transfer fuel burning equipment that burn wood fuel by itself or in combination with any other fuel, the emission results are corrected to 12% CO2.

(b) For indirect heat transfer fuel burning equipment that burn fuels other than wood, the emission results are corrected to 50% excess air.
