Authority: IC 13-14-8; IC 13-17-3
Affected: IC 13-15; IC 13-17
Sec. 12.
(a) The
following general requirements apply:
(1)
Each PAL permit must contain enforceable requirements for the monitoring system
that accurately determine plantwide emissions of the PAL pollutant in terms of
mass per unit of time. Any monitoring system authorized for use in the PAL
permit must be based on sound science and meet generally acceptable scientific
procedures for data quality and manipulation. Additionally, the information
generated by the system must meet minimum legal requirements for admissibility
in a judicial proceeding to enforce the PAL permit.
(2) The PAL monitoring system must employ one
(1) or more of the four (4) general monitoring approaches meeting the minimum
requirements set forth in subsection (b) and must be approved by the
department.
(3) Notwithstanding
subdivision (2), an alternative monitoring approach may be employed:
(A) that meets subdivision (1); and
(B) if it is approved by the
department.
(4) Failure
to use a monitoring system that meets the requirements of this section renders
the PAL invalid.
(b) The
following are acceptable general monitoring approaches when conducted in
accordance with the minimum requirements in subsections (c) through (i):
(1) Mass balance calculations for activities
using coatings or solvents.
(2)
CEMS.
(3) CPMS or PEMS.
(4) Emission factors.
(c) An owner or operator using mass balance
calculations to monitor PAL pollutant emissions from activities using coating
or solvents shall meet the following requirements:
(1) Provide a demonstrated means of
validating the published content of the PAL pollutant that is contained in or
created by all materials used in or at the emissions unit.
(2) Assume that the emissions unit emits all
of the PAL pollutant that is contained in or created by any raw material or
fuel used in or at the emissions unit if it cannot otherwise be accounted for
in the process.
(3) Where the
vendor of a material or fuel, which is used in or at the emissions unit,
publishes a range of pollutant content from the material, the owner or operator
must use the highest value of the range to calculate the PAL pollutant
emissions unless the department determines there is site-specific data or a
site-specific monitoring program to support another content within the
range.
(d) An owner or
operator using CEMS to monitor PAL pollutant emissions shall meet the following
requirements:
(1) CEMS must comply with
applicable performance specifications found in 40 CFR Part 60, Appendix
B*.
(2) CEMS must sample, analyze,
and record data at least every fifteen (15) minutes while the emissions unit is
operating.
(e) An owner
or operator using CPMS or PEMS to monitor PAL pollutant emissions shall meet
the following requirements:
(1) The CPMS or
the PEMS must be based on current site-specific data demonstrating a
correlation between the monitored parameters and the PAL pollutant emissions
across the range of operation of the emissions unit.
(2) Each CPMS or PEMS must sample, analyze,
and record data at least every fifteen (15) minutes, or at another less
frequent interval approved by the department, while the emissions unit is
operating.
(f) An owner
or operator using emission factors to monitor PAL pollutant emissions shall
meet the following requirements:
(1) All
emission factors shall be adjusted, if appropriate, to account for the degree
of uncertainty or limitations in the factors' development.
(2) The emissions unit shall operate within
the designated range of use for the emission factor if applicable.
(3) If technically practicable, the owner or
operator of a significant emissions unit that relies on an emission factor to
calculate PAL pollutant emissions shall conduct validation testing to determine
a site-specific emission factor within six (6) months of PAL permit issuance
unless the department determines that testing is not required.
(g) A source owner or operator
must record and report maximum potential emissions without considering
enforceable emission limitations or operational restrictions for an emissions
unit during any period of time that there is no monitoring data unless another
method for determining emissions during the periods is specified in the PAL
permit.
(h) Notwithstanding the
requirements in subsections (c) through (g), where an owner or operator of an
emissions unit cannot demonstrate a correlation between the monitored
parameters and the PAL pollutant emissions rate at all operating points of the
emissions unit, the department shall, at the time of permit issuance:
(1) establish default values for determining
compliance with the PAL based on the highest potential emissions reasonably
estimated at the operating points; or
(2) determine that operation of the emissions
unit during operating conditions when there is no correlation between monitored
parameters and the PAL pollutant emissions is a violation of the PAL.
(i) All data used to establish the
PAL pollutant must be revalidated through performance testing or other
scientifically valid means approved by the department. The testing must occur
at least once every five (5) years after issuance of the PAL.
