(c) Any facility covered by subpart Cb, Eb, AAAA, or BBBB of this part is not covered by this subpart.

(d) Any facility covered by an EPA approved State section 111(d)/129 plan implementing subpart Cb or BBBB of this part is not covered by this subpart.

(e) Any facility covered by subpart FFF or JJJ of part 62 of this title (Federal section 111(d)/129 plan implementing subpart Cb or BBBB of this part) is not covered by this subpart.

§ 60.51   Definitions.

As used in this subpart, all terms not defined herein shall have the meaning given them in the Act and in subpart A of this part.

(a) Incinerator means any furnace used in the process of burning solid waste for the purpose of reducing the volume of the waste by removing combustible matter.

(b) Solid waste means refuse, more than 50 percent of which is municipal type waste consisting of a mixture of paper, wood, yard wastes, food wastes, plastics, leather, rubber, and other combustibles, and noncombustible materials such as glass and rock.

(c) Day means 24 hours.

[36 FR 24877, Dec. 23, 1971, as amended at 39 FR 20792, June 14, 1974]

§ 60.52   Standard for particulate matter.

(a) On and after the date on which the initial performance test is completed or required to be completed under §60.8 of this part, whichever date comes first, no owner or operator subject to the provisions of this part shall cause to be discharged into the atmosphere from any affected facility any gases which contain particulate matter in excess of 0.18 g/dscm (0.08 gr/dscf) corrected to 12 percent CO₂.

[39 FR 20792, June 14, 1974, as amended at 65 FR 61753, Oct. 17, 2000]

§ 60.53   Monitoring of operations.

(a) The owner or operator of any incinerator subject to the provisions of this part shall record the daily charging rates and hours of operation.

§ 60.54   Test methods and procedures.

(a) In conducting the performance tests required in §60.8, the owner or operator shall use as reference methods and procedures the test methods in appendix A of this part or other methods and procedures as specified in this section, except as provided in §60.8(b).

(b) The owner or operator shall determine compliance with the particulate matter standard in §60.52 as follows:

(1) The concentration (c₁₂) of particulate matter, corrected to 12 percent CO₂, shall be computed for each run using the following equation:

c₁₂= c_s(12/%CO₂)

where:

c₁₂=concentration of particulate matter, corrected to 12 percent CO₂, g/dscm (gr/dscf).

c_s=concentrationofparticulatematter,g/dscm (gr/dscf).

%CO₂=CO₂concentration, percent dry basis.

(2) Method 5 shall be used to determine the particulate matter concentration (c_s). The sampling time and sample volume for each run shall be at least 60 minutes and 0.85 dscm (30 dscf).

(3) The emission rate correction factor, integrated or grab sampling and analysis procedure of Method 3B shall be used to determine CO₂concentration (%CO₂).

(i) The CO₂sample shall be obtained simultaneously with, and at the same traverse points as, the particulate run. If the particulate run has more than 12 traverse points, the CO₂traverse points may be reduced to 12 if Method 1 is used to locate the 12 CO₂traverse points. If individual CO₂samples are taken at each traverse point, the CO₂concentration (%CO₂) used in the correction equation shall be the arithmetic mean of the sample CO₂concentrations at all traverse points.

(ii) If sampling is conducted after a wet scrubber, an “adjusted” CO₂concentration [(%CO₂)_adj], which accounts for the effects of CO₂absorption and dilution air, may be used instead of the CO₂concentration determined in this paragraph. The adjusted CO₂concentration shall be determined by either of the procedures in paragraph (c) of this section.

(c) The owner or operator may use either of the following procedures to determine the adjusted CO₂concentration.

(1) The volumetric flow rates at the inlet and outlet of the wet scrubber and the inlet CO₂concentration may be used to determine the adjusted CO₂concentration [(%CO₂)_adj] using the following equation:

(%CO₂)_adj=(%CO₂)_di(Q_di/Q_do)

where:

(%CO₂)_adj=adjusted outlet CO₂concentration, percent dry basis.

(%CO₂)_di=CO₂concentration measured before the scrubber, percent dry basis.

Q_di=volumetric flow rate of effluent gas before the wet scrubber, dscm/min (dscf/min).

Q_do=volumetric flow rate of effluent gas after the wet scrubber, dscm/min (dscf/min).

(i) At the outlet, Method 5 is used to determine the volumetric flow rate (Q_do) of the effluent gas.

(ii) At the inlet, Method 2 is used to determine the volumetric flow rate (Q_di) of the effluent gas as follows: Two full velocity traverses are conducted, one immediately before and one immediately after each particulate run conducted at the outlet, and the results are averaged.

(iii) At the inlet, the emission rate correction factor, integrated sampling and analysis procedure of Method 3B is used to determine the CO₂concentration [(%CO₂)_di] as follows: At least nine sampling points are selected randomly from the velocity traverse points and are divided randomly into three sets, equal in number of points; the first set of three or more points is used for the first run, the second set for the second run, and the third set for the third run. The CO₂sample is taken simultaneously with each particulate run being conducted at the outlet, by traversing the three sampling points (or more) and sampling at each point for equal increments of time.

(2) Excess air measurements may be used to determine the adjusted CO₂concentration [(%CO₂)_adj] using the following equation:

(%CO₂)_adj=(%CO₂)_di[(100+%EA_i)/(100+%EA_o)]

where:

(%CO₂)_adj=adjusted outlet CO₂concentration, percent dry basis.

(%CO₂)_di=CO₂concentration at the inlet of the wet scrubber, percent dry basis.

%EA_i=excess air at the inlet of the scrubber, percent.

%EA_o=excess air at the outlet of the scrubber, percent.

(i) A gas sample is collected as in paragraph (c)(1)(iii) of this section and the gas samples at both the inlet and outlet locations are analyzed for CO₂, O₂, and N₂.

(ii) Equation 3B–3 of Method 3B is used to compute the percentages of excess air at the inlet and outlet of the wet scrubber.
