Current through Vol. 42, No. 4, November 1, 2024
Section 252:100-17-20 - Standards for nitrogen oxides
(a)Nitrogen oxides emission limits. The concentration of nitrogen oxides contained in the gases discharged into the atmosphere from a MWC unit shall not exceed the following:

a Corrected to 7 percent oxygen, dry basis, 24 hr daily arithmetic average

(b)Nitrogen oxides emissions averaging. The owner or operator of a MWC plant may elect to implement a nitrogen oxides emissions averaging plan for the MWC units that are located at that plant.
(1) The following units cannot be included in the emissions averaging plan:
(A) MWC units subject to Subpart Ea or Eb of 40 CFR Part 60.
(B) Mass burn refractory MWC units and other MWC technologies not listed in paragraph (b)(3) of this section may not be included in the emissions averaging plan.
(2) Prior to implementing the nitrogen oxides emissions averaging plan, the units to be included must be identified in the initial performance test report specified in 40 CFR 60.59b(f) or in the annual report specified in 40 CFR 60.59b(g), as applicable. The units which are included in the averaging plan may be redesignated each calendar year. Partial year redesignation is allowable with DEQ approval.
(3) To implement the emissions averaging plan, the average daily (24-hour) nitrogen oxides emission concentration level discharged from the units included in the emission averaging plan shall be no greater than the levels specified in this section. Emission limits for the nitrogen oxides concentration level for each type of unit are as follows:

a Mass burn refractory municipal waste combustors and other MWC technologies not listed above may not be included in an emissions averaging plan.
b Corrected to 7 percent oxygen, dry basis, 24 hr daily arithmetic average

(4) Under the emissions averaging plan, the average daily nitrogen oxides emissions specified in paragraph (b)(3) of this section shall be calculated using the equation in Appendix K of this Chapter. MWC units that are off-line shall not be included in calculating the average daily nitrogen oxides emission level.
(5) For any day a unit included in the emissions averaging plan is off-line, the owner or operator of the MWC plant must demonstrate compliance according to either paragraph (b)(5)(A) or both paragraphs (b)(5)(B) and (b)(5)(C) of this section.
(A) Compliance with the applicable limits specified in (b)(3) of this Part shall be demonstrated using the averaging procedure specified in paragraph (b)(4) of this section. The averaging procedure will include the MWC units in the plan that are on-line.
(B) For each of the units included in the emissions averaging plan, the nitrogen oxides emissions shall be calculated on a daily average basis. The nitrogen oxides emissions level shall be equal to or less than the maximum daily nitrogen oxides emission levels achieved by that unit on any of the days during which the emissions averaging plan was achieved with all units on-line during the most recent calendar quarter. The requirements of this paragraph do not apply during the first quarter of operation under the emissions averaging plan.
(C) The average nitrogen oxides emissions (kilograms per day) calculated according to paragraph (b)(5)(C)(ii) of this section shall not exceed the average nitrogen oxides emissions (kilograms per day) calculated according to paragraph (b)(5)(C)(i) of this section.
(i) The average nitrogen oxides emissions shall be calculated for all days during which the emissions averaging plan was implemented and achieved and during which all MWC units were on-line. The average nitrogen oxides emissions (kilograms per day) shall be calculated, on a calendar year basis, according to paragraphs (b)(5)(C)(i)(I) through (b)(5)(C)(i)(III) of this section.
(I) The daily amount of nitrogen oxides emitted (kilograms per day) shall be calculated for each MWC unit included in the emissions averaging plan. The calculation shall be based on the hourly nitrogen oxides data required under 40 CFR 60.58b(h) and specified under 40 CFR 60.58b(h)(5). The flue gas flow rate is determined using the hourly average steam or feedwater flow rate and Table 19-1 of EPA Reference Method 19, which is hereby incorporated by reference as it exists on July 1, 2002.
(II) The daily total nitrogen oxides emissions shall be calculated as the sum of the daily nitrogen oxides emissions from each unit calculated under paragraph (b)(5)(C)(i)(I) of this section.
(III) On a calendar year basis, the average nitrogen oxides emissions (kilograms per day), shall be calculated as the sum of all daily total nitrogen oxides emissions calculated under paragraph (b)(5)(C)(i)(II) of this section divided by the number of calendar days for which a daily total was calculated.
(ii) The average nitrogen oxides emissions shall be calculated for all days during which one or more of the MWC units under the emissions averaging plan was off-line. The average nitrogen oxides emissions (kilograms per day) shall be calculated according to paragraphs (b)(5)(C)(ii)(I) through (b)(5)(C)(ii)(III) of this section on a calendar year basis.
(I) For each MWC unit included in the emissions averaging plan, the daily amount of nitrogen oxides emitted (kilograms per day) shall be calculated based on the hourly nitrogen oxides data required under 40 CFR 60.58b(h) and specified under 40 CFR 60.58b(h)(5), the flue gas flow rate determined using Table 19-1 of the EPA Reference Method 19, which is hereby incorporated by reference as it exists on July 1, 2002 and the hourly average steam or feedwater flow rate.
(II) The daily total nitrogen oxides emissions shall be calculated as the sum of the daily nitrogen oxides emissions from each MWC unit as calculated under paragraph (b)(5)(C)(ii)(I) of this section.
(III) The average nitrogen oxides emissions (kilograms per day) on a calendar year basis shall be calculated as the sum of all daily total nitrogen oxides emissions calculated under paragraph (b)(5)(C)(ii)(II) of this section divided by the number of calendar days for which a daily total was calculated.
