Current through Register Vol. 47, No. 3, July 24, 2024
(1)
Continuous monitoring of opacity from coal-fired steam generating
				units.
The owner or operator of any coal-fired or coal-gas-fired steam
				generating unit with a rated capacity of greater than 250 million Btu per hour
				heat input shall install, calibrate, maintain, and operate continuous
				monitoring equipment to monitor opacity. If an exhaust services more than one
				steam generating unit as defined in the preceding sentence, the owner has the
				option of installing opacity monitoring equipment on each unit or on the common
				stack. Such monitoring equipment shall conform to performance specifications
				specified in 21.10(9). The director may require the owner or operator of any
				coal-fired or coal-gas-fired steam generating unit to install, calibrate,
				maintain, and operate continuous monitoring equipment to monitor opacity
				whenever the compliance status, history of operations, ambient air quality in
				the vicinity surrounding the generator, or the type of control equipment
				utilized would warrant such monitoring.
(2) and (3) Reserved.
(4)
Continuous monitoring of sulfur
				dioxide from sulfuric acid plants.
The owner or operator of any
				sulfuric acid plant of greater than 300 tons per day production capacity, the
				production being expressed as 100 percent acid, shall install, calibrate,
				maintain, and operate continuous monitoring equipment to monitor sulfur dioxide
				emissions. The monitoring equipment shall conform to the minimum performance
				specifications specified in 21.10(9).
(5)
Maintenance of records of
				continuous monitors.
The owner or operator of any facility that is
				required to install, calibrate, maintain, and operate continuous monitoring
				equipment shall maintain, for a minimum of two years, a file of all information
				pertinent to each monitoring system present at the facility. Such information
				must include but is not limited to all emissions data (raw data, adjusted data,
				and any or all adjusted factors used to convert emissions from units of
				measurement to units of the applicable standard), performance evaluations,
				calibrations and zero checks, and records of all malfunctions of monitoring
				equipment or source and repair procedures performed.
(6)
Reporting of continuous
				monitoring information.
The owner or operator of any facility required
				to install a continuous monitoring system or systems shall provide quarterly
				reports to the director, no later than 30 calendar days following the end of
				the calendar quarter, on forms provided by the director. This provision shall
				not excuse compliance with more stringent applicable reporting requirements.
				All periods of recorded emissions in excess of the applicable standards, the
				results of all calibrations and zero checks and performance evaluations
				occurring during the reporting period, the number of hours that the source was
				operated while the monitoring equipment was not in operation, and any periods
				of monitoring equipment malfunctions or source upsets and any apparent reasons
				for these malfunctions and upsets shall be included in the report.
(7)
Tests by owner.
The
				owner of new or existing equipment or the owner's authorized agent shall
				conduct emission tests to determine compliance with applicable rules in
				accordance with these requirements.
a.
General.
The owner of new or existing equipment or the owner's
				authorized agent shall notify the department in writing not less than 30 days
				before a required test or before a performance evaluation of a continuous
				emission monitor to determine compliance with applicable requirements of
				567-Chapter 23 or a permit condition. Such notice shall include the time, the
				date, the place, the name of the person who will conduct the tests, and other
				information as required by the department. If the owner or operator does not
				provide timely notice to the department, the department may not consider the
				test results or performance evaluation results to be a valid demonstration of
				compliance with applicable rules or permit conditions. Upon written request,
				the department may allow a notification period of less than 30 days. At the
				department's request, a pretest meeting shall be held not later than 15 days
				before the owner or operator conducts the compliance demonstration. A testing
				protocol shall be submitted to the department for review no later than 15 days
				before the owner or operator conducts the compliance demonstration. A
				representative of the department shall be permitted to witness the tests.
				Results of the tests shall be submitted in writing to the director in the form
				of a comprehensive report within six weeks (42 days) of the completion of the
				testing.
b.
New
				equipment.
Unless otherwise specified by the department, all new
				equipment shall be tested by the owner or the owner's authorized agent to
				determine compliance with applicable emission limits. Tests conducted to
				demonstrate compliance with the requirements of the rules or a permit shall be
				conducted within 60 days of achieving maximum production but no later than 180
				days of startup, unless a shorter time frame is specified in the
				permit.
c.
Existing
				equipment.
The director may require the owner or the owner's
				authorized agent to conduct an emission test on any equipment if the director
				has reason to believe that the equipment does not comply with applicable
				requirements. Grounds for requiring such a demonstration of compliance include
				a modification of control or process equipment, age of equipment, or
				observation of opacities or other parameters outside the range of those
				indicative of properly maintained and operated equipment. Testing may be
				required as necessary to determine actual emissions from a source where that
				source is believed to have a significant impact on the public health or ambient
				air quality of an area. The director shall provide the owner or agent not less
				than 30 days to perform the compliance demonstration and shall provide written
				notice of the requirement.
