326 IAC 10-2-8.5 - Alternative monitoring and reporting
Authority: IC 13-14-8; IC 13-17-3-4; IC 13-17-3-11
Affected: IC 13-15; IC 13-17
Sec. 8.5.
(a) Owners
and operators of a large affected unit subject to this rule may use an
alternative monitoring method and comply with the reporting requirements
established in an operating permit in lieu of the requirements in sections 3
through 8 of this rule, if:
(1) approved by
the department as sufficient to demonstrate compliance with the ozone season
NOx emissions budget established under section 9 of this
rule; and
(2) consistent with the
requirements in this section.
(b) To request use of alternative monitoring
and reporting requirements in this section, the owner or operator of a large
affected unit shall submit an application for an operating permit or an
application for a modification to an existing operating permit issued in
accordance with 326 IAC 2.
(c) The
application must include all of the following:
(1) An indication of which of the following
alternatives is being requested:
(A)
Monitoring in accordance with 40 CFR 60 *.
(B) Monitoring in accordance with 40 CFR 75
*, except that:
(i) references to the
"Administrator" in 40 CFR 75* means the department; and
(ii) reporting of data to U.S. EPA through
electronic means in accordance with 40 CFR 75*, Subpart G, does not
apply.
(C) Monitoring of
heat input and fuel use using a fuel flowmeter, with NOx
emission rate determined through an emissions monitoring system certified,
operated, and maintained in accordance with 40 CFR 60*.
(D) Monitoring of heat input and fuel use and
an approved emission factor for determination of NOx
emissions. Liquid or gaseous fuel use must be measured using meters calibrated
to the levels of accuracy specified in:
(i)
Section 2.1.5 of 40 CFR 75, Appendix D*;
(ii)
40 CFR
98.3(i) *;
(iii) the ASME standards at
40 CFR
98.7 *; or
(iv) other procedures recommended by the
manufacturer.
(2) A description of the proposed monitoring
procedures, including how:
(A) data will be
obtained, recorded, and quality assured; and
(B) NOx emissions will
be accounted for during periods of missing data, such as periods of maintenance
or malfunction.
(3)
Emission monitoring data must be reported as provided in subsection
(e).
(4) If monitoring of heat
input and fuel use and an approved emission factor under subdivision (1)(D) is
requested as the alternative, an emission factor analysis evaluating potential
emission factors in pounds of NOx emitted per unit of
fuel and heat input, for each fuel type, based on one (1) of the following:
(A) U.S. EPA's Compilation of Air Pollutant
Emissions Factors, AP-42*, as described in
326 IAC 1-1-3.5.
(B) A valid stack test using 40 CFR 60,
Appendix A, Method 3*, Method 7*, and Method 19*, conducted within the previous
two (2) years from the date of the application submittal, if
available.
(C) An analysis of
continuous emission monitoring data representative of current operating
conditions.
(D) An analysis of
other relevant data or emission factors, if available.
(5) If monitoring and annual reporting of
ozone control period NOx emissions in accordance with 40
CFR 60 * under subdivision (1)(A) or (1)(C) is requested, an explanation for
how the amount of NOx emissions in tons per ozone
control period will be determined from the NOx emission
rate data in accordance with 40 CFR 60*.
(6) If alternative monitoring and reporting
is requested to begin within an ozone control period, a description of the
transition process that ensures there will not be gaps in data collection and
reporting of ozone control period NOx
emissions.
(d) Prior to
the use of alternative monitoring and reporting, one (1) of the following must
be specified in an operating permit issued in accordance with 326 IAC 2:
(1) Applicable terms and conditions,
including monitoring and reporting requirements in accordance with 40 CFR 60*
or 40 CFR 75 *.
(2) An emission
factor and monitoring procedure for fuel use and heat
input.
(e) The owner or
operator of a large affected unit subject to alternative monitoring and
reporting under this section shall meet all of the following:
(1) Comply with all terms and conditions
specified in the operating permit.
(2) Install all data collection and recording
systems required for alternative monitoring.
(3) Record and report the data from the
monitoring systems required under this section in accordance with the terms and
conditions in the operating permit.
(4) By April 15 each year, report
NOx emissions in tons to the department, as determined
using the approved alternative monitoring procedures, for the previous ozone
control period.
(5) If alternative
monitoring is based on an approved emission factor, the following requirements
apply:
(A) Conduct stack tests to demonstrate
the approved emission factor continues to be representative of current
operating conditions.
(B) If the
emissions factor analysis submitted in accordance with subsection (c)(2) did
not include a stack test, an initial stack test must be conducted within ninety
(90) days of permit issuance.
(C)
Ongoing stack tests must be conducted at least once every five (5) years from
the date of approval of the alternative monitoring request.
(D) Stack tests must be conducted in
accordance with a test method specified in the operating permit and reported to
the department within forty-five (45) days of the test.
(E) If a stack test indicates an emission
factor may require upward adjustment, the owner or operator shall use the
revised emission factor to report NOx emissions in tons
per ozone control period and submit an application for a modification to an
operating permit within sixty (60) days of receiving stack test
results.
(6) Maintain
records in accordance with the terms and conditions in the operating permit for
a period of not less than five (5) years from the date the records are created.
These records must be made available to the department upon request.
(f) An owner or operator of a
large affected unit subject to this section shall not do the following:
(1) Operate the unit so as to discharge, or
allow to be discharged, NOx emissions to the atmosphere
during an ozone control period without accounting for all emissions in
accordance with the applicable provisions of this section.
(2) Retire or permanently discontinue use of
the monitoring system, or any component thereof, except when discontinuing use
of alternative monitoring and reporting in accordance with this section and
resuming compliance with monitoring and reporting requirements in accordance
with sections 3 through 8 of this rule. This may only occur outside of an ozone
control period.
(g) This
section does not authorize exceptions or alternatives to any 40 CFR Part 75
monitoring requirements that apply to a source under a different legal
authority.
(h) In accordance with
the requirements of 40 CFR
51.122(c)(1)(i) *, the
department shall report annually to U.S. EPA all NOx
emissions reported under this section.
