Improve specificity of NOx and SO2 emissions factors used for imputing emissions about open-grid-emissions HOT 3 CLOSED

Specifically, the new data we would need to integrate includes:

EIA-860

• File: 6_1_EnviroAssoc_Y20XX
  • Table: 'Emissions Control Equipment',
    • S02 control technology / equipment type
    • NOx control technology / equipment type
  • Table: 'Boiler / SO2 Control Associations',
  • Table: 'Boiler / NOx Control Associations',
• File: 6_2_EnviroEquip_Y20XX
  • Table: Schedule 6B, 'Emission Standards and Control Strategies'
  • Table: Schedule 6C, 'Boiler Information - Design Parameters'
    • column: firing type
    • column: bottom type

EIA-923

• File: EIA923_Schedule_8_Annual_Environmental_Information_20XX_Final
  • Table: 923 Schedule 8C, 'Air Emissions Control Info'
    • column: NOx emission rate
    • column: SO2 removal efficiency

from open-grid-emissions.

Some thoughts while working on this:

• We are aggregating the boiler-specific NOx rates to generators for the EIA-923 allocation process. However, if this data were integrated into pudl, we could calculate boiler-specific NOx outputs using data from the bf table then allocate this.
• When filling missing Nox data in CEMS, we would want to aggregate the NOx rates to the boiler level then use the EPA crosswalk.

Do reported NOx emissions in CEMS already take controls into account?
