Current through Register Vol. 51, No. 14, July 12, 2024
A.
				  Monitoring and Record Keeping Requirements.
(1) Each PAL permit shall 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 shall be based on sound
				  science and meet generally acceptable scientific procedures for data quality
				  and manipulation. Additionally, the information generated by the system shall
				  meet the minimum legal requirements for admissibility in a judicial proceeding
				  to enforce the PAL permit.
(2) The
				  PAL monitoring system shall employ one or more of the four general monitoring
				  approaches meeting the minimum requirements set forth in §A(5) of this
				  regulation and shall be approved by the Department.
(3) Notwithstanding §A(2) of this regulation,
				  an alternative monitoring approach may be used that meets the requirements of
				  §A(1) of this regulation if approved by the Department.
(4) Failure to use a monitoring system that
				  meets the requirements of this section renders the PAL invalid.
(5) The following are acceptable general
				  monitoring approaches when conducted in accordance with the minimum performance
				  requirements in §A(6)-(12) of this regulation:
(a) Mass balance calculations for activities
				  using coatings or solvents;
(b)
				  CEMs;
(c) CPMs or PEMs;
				  and
(d) Emission factors.
(6) Mass Balance Calculations. An
				  owner or operator using mass balance calculations to monitor PAL pollutant
				  emissions from activities using coatings or solvents shall meet the following
				  requirements:
(a) 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;
(b) 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; and
(c) Where the vendor of a material or fuel
				  which is used in or at the emissions unit publishes a range of pollutant
				  content from that material, the owner or operator shall 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.
(7) CEMs. An owner or operator using CEMs to
				  monitor PAL pollutant emissions shall meet the following requirements:
(a) CEMs shall comply with the applicable
				  performance specifications found in 40 CFR Part 60, Appendix B; and
(b) CEMs shall sample, analyze, and record
				  data at least every 15 minutes while the emissions unit is operating.
(8) CPMs or PEMs. An owner or
				  operator using CPMs or PEMs to monitor PAL pollutant emissions shall meet the
				  following requirements:
(a) The CPMs or the
				  PEMs shall be based on current site specific data demonstrating a correlation
				  between the monitored parameters and PAL pollutant emissions across the range
				  of operation of the emissions unit; and
(b) Each CPMs or PEMs shall sample, analyze,
				  and record data at least every 15 minutes, or at another less frequent interval
				  approved by the Department, while the emissions unit is operating.
(9) Emission Factors. An owner or
				  operator using emission factors to monitor PAL pollutant emissions shall meet
				  the following requirements:
(a) All emission
				  factors shall be adjusted, if appropriate, to account for the degree of
				  uncertainty or limitations in the factor development;
(b) The emissions unit shall operate within
				  the designated range of use for the emission factor, if applicable;
				  and
(c) 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 6 months of PAL
				  permit issuance, unless the Department determines that testing is not
				  required.
(10) A source
				  owner or operator shall 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 this period is specified
				  in the PAL permit.
(11)
				  Notwithstanding the requirements in §A(6)-(10) of this regulation, when 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:
(a) Establish default values for
				  determining compliance with the PAL based on the highest potential emission
				  reasonably estimated at the operating point; or
(b) 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.
(12) Revalidation. All data used
				  to establish the PAL pollutant shall be revalidated through performance testing
				  or other scientifically valid means approved by the Department. This testing
				  shall occur at least once every 5 years after issuance of the PAL.
(13) The PAL permit shall require an owner or
				  operator to retain a copy of all records necessary to determine compliance with
				  any requirement of Regulations .07-.09 of this chapter and of the PAL,
				  including a determination of each emissions unit's 12-month rolling total
				  emissions for 5 years from the date of that record.
(14) The PAL permit shall require an owner or
				  operator to retain a copy of the following records for the duration of the PAL
				  effective period plus 5 years:
(a) A copy of
				  the PAL permit application and any application for revisions to the PAL;
				  and
(b) Each annual certification
				  of compliance pursuant to Title V and the data relied on in certifying the
				  compliance.
