• switch to using TIGER 2020 shapefiles. Punted to Switch to using 2020 TIGER geometries and 2020 Census vintage #121
• Check if MSHA filtering is done as specified in FAQs:
  • "Surface" or "Underground" type mines, "Abandoned" or "Abandoned and Sealed" status
• Check if EIA coal plant filtering is done as specified in the FAQs:
  • at the time of being classified as "retired" it is listed a coal fired electric generating unit
  • technology is “Conventional Steam Coal” or “Coal Integrated Gasification Combined Cycle"
  • For years 2010 to 2013, coal-fired electric generating units are those listed in EIA Form 860 data as having a primary fuel source code of anthracite coal, bituminous coal, lignite coal, refined coal, coal-derived synthesis gas, subbituminous coal, and waste/other coal
• Check if brownfields filtering is done as specified in the FAQs
  • "defined in 42 U.S.C. 9601(39) (A), (B), and (D)(ii)(III))"
• Check MSA + non-MSA area definitions in Appendix A in IRS Notice 2023-29
  • See Switch to using Census MSA delineations? #116
• Update fossil NAICS codes to reflect those under FAQ "How is fossil fuel employment estimated for MSAs and non-MSAs?"
• Check/fix non-MSA boundaries in New England states according to this guidance:

For MSAs, these boundaries directly follow OMB Bulletin No. 18-03. The non-MSAs in these New England states delineated in IRS Notice 2023-29 include the counties in a BLS defined nonmetropolitan area that have no portion in an MSA
• Handle adjoining Census tracts that are separated by a river/waterway. Punted to Switch to using 2020 TIGER geometries and 2020 Census vintage #121
