Chapter NR 408

NR 408.11(12)(a)1. 1. Each PAL permit shall contain enforceable requirements for the monitoring system that accurately determines plantwide emissions of the PAL regulated air contaminant 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 any authorized system shall meet minimum legal requirements for admissibility in a judicial proceeding to enforce the PAL permit.

NR 408.11(12)(a)2. 2. Except as provided for in subd. 3., the PAL monitoring system shall employ one or more of the 4 general monitoring approaches meeting the minimum requirements in par. (b) and shall be approved by the department.

NR 408.11(12)(a)3. 3. Notwithstanding subd. 2., the owner or operator may employ an alternative monitoring approach that meets subd. 1. if approved by the department.

NR 408.11(12)(a)4. 4. Failure to use a monitoring system that meets the requirements of this subsection renders the PAL invalid.

NR 408.11(12)(b) (b) The following are acceptable general monitoring approaches when conducted in accordance with the minimum requirements in pars. (c) to (i):

NR 408.11(12)(b)1. 1. Mass balance calculations for activities using coatings or solvents.

NR 408.11(12)(b)2. 2. CEMS.

NR 408.11(12)(b)3. 3. CPMS or PEMS.

NR 408.11(12)(b)4. 4. Emission factors.

NR 408.11(12)(c) (c) An owner or operator using mass balance calculations to monitor PAL regulated air contaminant emissions from activities using coating or solvents shall do all of the following:

NR 408.11(12)(c)1. 1. Provide a demonstrated means of validating the published content of the PAL regulated air contaminant that is contained in or created by all materials used in or at the emissions unit.

NR 408.11(12)(c)2. 2. Assume that the emissions unit emits all of the PAL regulated air contaminant 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.

NR 408.11(12)(c)3. 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, use the highest value of the range to calculate the PAL regulated air contaminant emissions unless the department determines there is site-specific data or a site-specific monitoring program to support another content within the range.

NR 408.11(12)(d) (d) An owner or operator using CEMS to monitor PAL regulated air contaminant emissions shall ensure that the CEMS does both of the following:

NR 408.11(12)(d)1. 1. Complies with applicable performance specifications found in 40 CFR part 60, Appendix B incorporated by reference in s. NR 484.04 (21).

NR 408.11(12)(d)2. 2. Samples, analyzes and records data at least every 15 minutes while the emissions unit is operating.

NR 408.11(12)(e) (e) An owner or operator using CPMS or PEMS to monitor PAL regulated air contaminant emissions shall ensure that the CPMS or PEMS does both of the following:

NR 408.11(12)(e)1. 1. Is based on current site-specific data demonstrating a correlation between the monitored parameters and the PAL regulated air contaminant emissions across the range of operation of the emissions unit.

NR 408.11(12)(e)2. 2. Samples, analyzes and records data at least every 15 minutes, or at another less frequent interval approved by the department, while the emissions unit is operating.

NR 408.11(12)(f) (f) An owner or operator using emission factors to monitor PAL regulated air contaminant emissions shall do all of the following:

NR 408.11(12)(f)1. 1. Adjust all emission factors, if appropriate, to account for the degree of uncertainty or limitations in the factors’ development.

NR 408.11(12)(f)2. 2. Operate the emissions unit within the designated range of use for the emission factor, if applicable.

NR 408.11(12)(f)3. 3. If technically practicable, for a significant emissions unit that relies on an emission factor to calculate PAL regulated air contaminant emissions, 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.

NR 408.11(12)(g) (g) 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 the periods is specified in the PAL permit.

NR 408.11(12)(h) (h) Notwithstanding the requirements in pars. (c) to (g), where an owner or operator of an emissions unit cannot demonstrate a correlation between the monitored parameters and the PAL regulated air contaminant emissions rate at all operating points of the emissions unit, the department shall, at the time of permit issuance, do one of the following:

NR 408.11(12)(h)1. 1. Establish default values for determining compliance with the PAL based on the highest potential emissions reasonably estimated at the operating points.

NR 408.11(12)(h)2. 2. Determine that operation of the emissions unit during operating conditions when there is no correlation between monitored parameters and the PAL regulated air contaminant emissions is a violation of the PAL.

NR 408.11(12)(i) (i) All data used to establish the PAL regulated air contaminant level shall be re-validated through performance testing or other scientifically valid means approved by the department. The testing shall occur at least once every 5 years after the issuance of the PAL.

NR 408.11(13) (13) Recordkeeping requirements.

NR 408.11(13)(a) (a) The PAL permit shall require an owner or operator to retain a copy of all records necessary to determine compliance with any requirement of the PAL permit, including a determination of each emissions unit’s 12-month rolling total emissions, for 5 years from the date of the record.
