WAC 173-441-040

Greenhouse gases.

(1) Greenhouse gases. Table A-1 of this section lists the GHGs regulated under this chapter and their global warming potentials.
(2) CO2e conversion. Use Equation A-1 of WAC 173-441-030 (1)(b)(iii) and the global warming potentials (GWP) listed in Table A-1 of this section to convert emissions into CO2e.

1 = Determining applicability for emissions years 2013 and 2014. For emissions year 2013 (reported in 2014) and emissions year 2014 (reported in 2015), facilities may use the GWPs in either column when calculating GHG emissions for comparison to the reporting threshold under WAC 173-441-030(1).
 
2 = Calculating annual GHG emissions for emissions year 2013. For emissions year 2013 (reported in 2014), facilities may use the GWPs in either column when calculating GHG emissions for the annual GHG report.
 
3 = Determining applicability for emissions year 2015+. For emissions year 2015 (reported in 2016) and subsequent years, facilities must use the GWPs in this column when calculating GHG emissions for comparison to the reporting threshold under WAC 173-441-030(1).
 
4 = Calculating annual GHG emissions for emissions year 2014+. For emissions year 2014 (reported in 2015) and subsequent years, facilities must use the GWPs in this column when calculating GHG emissions for the annual GHG report.
 
* = Requirements to include emissions of this compound when calculating GHG emissions for comparison to the reporting threshold under WAC 173-441-030(1) and when calculating GHG emissions for the annual GHG report become effective beginning with emissions year 2016 (reported in 2017).
