Current through July 10, 2024
Authority: IC 13-14-8; IC 13-17-3-4; IC 13-17-3-11
Affected: IC 13-14-4-3; IC 13-15; IC 13-17
Sec. 5.
(a) Tests for
				particulate matter (PM), PM10, and
				PM2.5 shall be conducted in accordance with the
				following procedures:
(1) For PM: 40 CFR 60,
				Appendix A, Method 5*, 5A*, 5B*, 5C*, 5D*, 5E*, or 5F*, or Method 17*, as
				applicable, or other procedures approved by the department and U.S.
				EPA.
(2) For
				PM10 and PM2.5: 40 CFR 51,
				Appendix M, Method 201* or 201A*, and 202*. The measurement of condensable
				PM10 using the procedures described in Method 202* is
				not required if the applicable emission limitation is contained at 326 IAC
				6.8-2, unless otherwise specified by 326 IAC 6.5 or 326 IAC 6.8. 40 CFR 60,
				Appendix A, Method 5*, in conjunction with Method 202*, may also be used,
				subject to the approval of the department and U.S. EPA. Other procedures to
				measure PM10 and PM2.5 may be
				approved by the department and U.S. EPA.
(3) Visible emissions (VE) evaluations shall
				be performed in conjunction with a PM, PM10,
				PM2.5, or other mass emission rate test of air
				pollutants, as required by the department. The VE evaluations shall be
				conducted by a qualified observer in accordance with the procedures contained
				in 326 IAC 5-1-4. VE readings shall be continuously recorded for at least
				thirty (30) minutes per hour of sampling time for each sampling repetition,
				unless a longer time is otherwise mandated by federal regulation. A waiver from
				this requirement may be granted by the department or on-site department staff
				person if adverse conditions exist that would invalidate the VE readings.
				Complete waivers from the requirement to conduct VE readings during a
				compliance test may not be granted for the emissions unit required to complete
				opacity testing pursuant to 40 CFR 60.8 * or 40 CFR 63 *. VE readings are not
				required for units when operating a certified PM CEMS. Emissions units equipped
				with continuous opacity monitors may submit the six (6) minute integrated
				readings of the monitors during the sampling period, instead of performing VE
				evaluations, provided:
(A) the monitoring
				system meets the performance specifications as specified in 40 CFR 60, Appendix
				B*, and is, or will be, certified by the department;
(B) the monitor readings submitted with the
				test include a zero (0) and upscale calibration check before the first test run
				and following the end of the final run; and
(C) if more than one (1) day of testing is
				required to complete the three (3) runs, the zero (0) and span checks shall be
				performed at the beginning of each day's testing and at the conclusion of each
				day's final run.
(4) At
				least three (3) repetitions of the test shall be performed under consistent
				emissions unit operating conditions unless otherwise allowed by the department.
				For boiler emissions testing, at least one (1) of the three (3) repetitions
				shall be conducted during a normal sootblowing cycle that is consistent with
				frequency and duration normally experienced.
(5) At Richmond Power and Light's Whitewater
				Generating Station, when sootblowing occurs during one (1) of the three (3)
				repetitions, emission test results shall be evaluated using either a time
				weighted averaging period (TWAP) or a straight averaging technique. When using
				TWAP, the following equation shall be used to ensure proper weighting of an
				intermittent cleaning cycle performance test run regardless of the length of
				the cleaning cycle and regardless of the number and duration of the test runs
				made on the unit. When using TWAP, the representative pounds per hour of
				particulate emissions shall be calculated using the following equation:

Where: E = Pounds per hour of particulate emissions.
Ecc = Average E of sample containing
				  cleaning cycle.
Encc = Average E of sample containing
				  no cleaning cycle.
A = Hours of cleaning cycle operation during sample.
B = Hours with no cleaning cycle operation during sample.
R = Average hours of operation per twenty-four (24)
				  hours.
S = Average hours of cleaning cycle operation per twenty-four
				  (24) hours.
(6) Only those
				fuels representative of normal fuel quality used during normal operations shall
				be combusted.
(7) During each
				repetition, each sampling point shall be sampled for a minimum of two (2)
				minutes.
(8) The total test time
				per repetition shall be no less than sixty (60) minutes.
(9) The total sample volume per repetition
				shall be no less than thirty (30) dry standard cubic feet (dscf).
(10) The total particulate weight collected
				from the sampling nozzle, probe, cyclone (if used), filter holder (front half),
				filter, connecting glassware, and, if required in subdivision (2), the impinger
				catch, shall be reported to the department.
