§ 98.127 Records that must be retained.
In addition to the records required by § 98.3(g), you must retain the dated records specified in paragraphs (a) through (l) of this section, as applicable.
(a) Process information records. (1) Identify all products and processes subject to this subpart. Include the unit identification as appropriate, the generic process identification reported for the process under § 98.126(a)(2)(i) through (iii), and the product with which the process is associated.
(2) Monthly and annual records, as applicable, of all analyses and calculations conducted as required under § 98.123, including the data monitored under § 98.124, and all information reported as required under § 98.126.
(3) Identify all fluorinated GHGs with emissions of 1,000 metric tons CO2e or more from production and transformation processes, summed across the facility as a whole, and identify all fluorinated GHGs with total emissions less than 1,000 metric tons CO2e from production and transformation processes, summed across the facility as a whole.
(4) Calculations used to determine the total GWP-weighted emissions of fluorinated GHGs by fluorinated GHG group for each process, in metric tons CO2e.
(b) Scoping speciation. Retain records documenting the information collected under § 98.124(a).
(c) Mass balance method. Retain the following records for each process for which the mass balance method was used to estimate emissions in reporting years 2011, 2012, 2013, or 2014. If you used an element other than fluorine in the mass balance equation pursuant to the former § 98.123(b)(3) as included in paragraph 1 of Appendix A of this subpart for the former mass balance method, substitute that element for fluorine in the recordkeeping requirements of this paragraph.
(1) The data and calculations used to estimate the absolute and relative errors associated with use of the mass-balance approach.
(2) The data and calculations used to estimate the mass of fluorine emitted from the process.
(3) The data and calculations used to determine the fractions of the mass emitted consisting of each reactant (FERd), product (FEP), and by-product (FEBk), including the preliminary calculations in the former § 98.123(b)(8)(i).
(d) Emission factor and emission calculation factor method. Retain the following records for each process for which the emission factor or emission calculation factor method was used to estimate emissions.
(1) Identify all continuous process vents with emissions of fluorinated GHGs that are less than 10,000 metric tons CO2e per year and all continuous process vents with emissions of 10,000 metric tons CO2e per year or more. Include the data and calculation used to develop the preliminary estimate of emissions for each process vent.
(2) Identify all batch process vents.
