Sec. 1.
(a) This rule applies to the following sources or emissions units to determine compliance with an emission limitation or standard:
(1) Any emissions unit required to perform
continuous monitoring under 326 IAC 12.
(2) Fossil fuel-fired steam generators of
greater than one hundred million (100,000,000) British thermal units (Btu) per
hour heat input capacity.
(3)
Sulfuric acid plants of greater than three hundred (300) tons per day acid
production capacity.
(4) Petroleum
refinery catalyst regenerators for fluid bed catalytic cracking units of
greater than twenty thousand (20,000) barrels or eight hundred forty thousand
(840,000) gallons per day fresh feed capacity.
(5) Portland cement plants.
(6) Sources or emissions units that combust
sewage sludge.
(7) Sources or
emissions units making coke from raw materials, including the following:
(A) Coal refining byproducts.
(B) Petroleum refining byproducts.
(8) Emissions units in Clark and
Floyd counties that:
(A) have potential to
emit nitrogen oxides (NOx) of greater than or equal to
forty (40) tons per year; and
(B)
are located at sources that have potential to emit NOx
of greater than or equal to one hundred (100) tons per year as described in 326
IAC 10.
(9) Any
emissions unit required to monitor under subsection (c).
(b) Owners and operators of sources or emissions units described in subsection (a) are subject to the following requirements:
(1) Any emissions unit subject
to 326 IAC 12 must comply with the following:
(A) The monitoring and reporting requirements
as specified for the applicable rule.
(B) All requirements of this rule.
(2) The owner or operator of a
fossil fuel-fired steam generator of greater than one hundred million
(100,000,000) Btu per hour heat input capacity must continuously monitor the
following:
(A) Opacity, unless one (1) of the
following occurs:
(i) Gaseous fuel is the
only fuel combusted.
(ii) Oil or a
mix of gas and oil are the only fuels combusted and the emissions unit is able
to comply with both of the following rules without using particulate matter
collection equipment:
(AA)
326 IAC
5-1.
(BB)
326
IAC 6-2.
(iii) An alternative monitoring requirement request
has been granted by the department and approved by U.S. EPA. The owner or
operator may request an alternative monitoring requirement when installation of
an opacity monitoring system would not provide accurate determinations of
emissions as a result of interference from condensed uncombined water vapor.
Any alternative monitoring requirement request must address the following:
(AA) Information pertaining to the inability
of the affected emissions unit to find an acceptable monitoring location prior
to the source of the condensed, uncombined water vapor.
(BB) A list of proposed alternative
monitoring requirements. For each proposed alternative monitoring requirement,
the request must provide a detailed description of thresholds or triggers for
corrective action resulting from deviation from normal operating parameters and
how deviations from key surrogate parameters are to be addressed to ensure
continuous compliance with all applicable particulate and opacity requirements.
An example of an acceptable alternative monitoring requirement is a particulate
compliance demonstration that is performed at least annually, in accordance
with
326 IAC
3-6 and a compliance monitoring plan that, at a
minimum, satisfies monitoring requirements under
326 IAC
2-7 or
326
IAC 2-8.
(CC) Record keeping that is consistent with
section 6 of this rule.
(DD)
Reporting frequency that is no less frequent than that required in section 7 of
this rule.
(iv) An
alternative monitoring requirement request granted by the department under item
(iii) must be submitted to U.S. EPA as a state implementation plan (SIP)
revision and is not in effect until approved as a SIP
revision.
(B) Sulfur
dioxide (SO2) under the following conditions:
(i) SO2 pollution
control equipment has been installed.
(ii) A monitor is required to determine
compliance with either:
(AA) 326 IAC 12;
or
(BB) a new construction permit
or operating permit required under 326 IAC 2.
(C) Nitrogen oxide
(NOx) under the following conditions:
(i) NOx pollution
control equipment has been installed.
(ii) A monitor is required to determine
compliance with either:
(AA) 326 IAC 12;
or
(BB) a new construction permit
or operating permit required under 326 IAC 2.
(D) The percent oxygen
(O2) or carbon dioxide (CO2) if
measurements of O2 or CO2 in the
flue gas are required to convert either SO2 or
NOx continuous monitoring data, or both, to units of the
emission limitation for the particular emissions unit.
(3) Sulfuric acid plants of greater than
three hundred (300) tons per day acid production capacity must monitor
SO2 for each sulfuric acid producing emissions unit
within the source.
(4) Petroleum
refinery catalyst regenerators for fluid bed catalytic cracking units of
greater than twenty thousand (20,000) barrels or eight hundred forty thousand
(840,000) gallons per day fresh feed capacity must monitor opacity for each
regenerator within the source.
(5)
Portland cement plants must monitor opacity at kiln and clinker cooler emission
units.
(6) Sources or emissions
units that combust sewage sludge must monitor from the effluent gas exiting the
incinerator, the following:
(A) Total
hydrocarbons, unless the following conditions are met:
(i) The exit gas from the sewage sludge
incinerator stack is monitored continuously for carbon monoxide (CO).
(ii) The monthly average concentration of CO
in the exit gas from the sewage sludge incinerator stack, corrected for zero
percent (0%) moisture and to seven percent (7%) oxygen, does not exceed one
hundred (100) parts per million on a volumetric basis.
(B) Oxygen.
(C) Moisture, unless an alternative method is
approved by the department and the U.S. EPA.
(D) Temperature.
(7) Sources or emissions units making coke
from coal must monitor opacity on the underfire stack associated with each coke
oven battery.
(8) Emissions units
in Clark and Floyd counties that have potential to emit
NOx greater than or equal to forty (40) tons per year
and are located at sources that have potential to emit
NOx greater than or equal to one hundred (100) tons per
year must install NOx continuous emission monitors as
described in
326
IAC 10-1.
(c) The owner or operator of an emissions unit required to continuously monitor opacity under this section may be exempted from the requirement to install, certify, and operate a COMS if approved by the department based on the following:
(1) A particulate CEMS for measuring PM
emissions is:
(A) used to demonstrate
continuous compliance with any applicable emissions limitation; and
(B) installed, certified, operated, and
maintained on the affected source in accordance with the requirements of:
(i) Performance Specification 11 (PS-11)*;
and
(ii) Procedure 2 of 40 CFR 60,
Appendix F*.
(2) For Portland cement plants, a continuous
parametric monitoring system (CPMS) for measuring particulate matter (PM)

compliance with any applicable emissions limitation; and
(B) installed, calibrated, certified,
operated, and maintained on the affected kiln or clinker cooler emission unit
in accordance with the requirements of:
(i)40
CFR 63, Subpart LLL*; and
(ii)
326
IAC 20-27-1.
(d) The department may require, as a condition of a construction or operating permit issued under 326 IAC 2-1.1, 326 IAC 2-2, 326 IAC 2-3, 326 IAC 2-7, 326 IAC 2-8, or 326 IAC 2-9 that the owner or operator of a new or existing source of air emissions monitor emissions to ensure compliance with the following:
(1) An emission limitation or
standard established in one (1) of the permits listed in this
subsection.
(2) Permit
requirements.
(3) Monitoring
requirements in 326 IAC 7.
(e) Unless explicitly stated otherwise, nothing in this rule:
(1) excuses the owner or
operator of a source or emissions unit from any monitoring, record keeping, or
reporting requirement that applies under any provision of the CAA or state
statutes or rules; or
(2) restricts
the authority of the department to impose additional or more restrictive
monitoring, record keeping, testing, or reporting requirements on any owner or
operator of a source or emissions unit under any other provision of the CAA,
including Section 114(a)(1), or state statutes or rules, as
applicable.
(f) All continuous monitoring systems must be installed and operational and have the certification testing complete under section 3 of this rule within one hundred eighty (180) days of start-up of the emissions unit.
