Ecology must assign a GHG emission reduction pathway to all covered parties with baseline GHG emissions values greater than or equal to 70,000 MT CO2e, or when requested by a voluntary participant.

(1) For non-EITE covered parties, ecology assigns the GHG emission reduction pathway to the covered party based on their baseline GHG emissions value.

(a) The GHG emission reduction pathway for the first calendar year a covered party meets or exceeds the compliance threshold in WAC 173-442-030(3) is the baseline GHG emissions value for that covered party.

(b) Annual decrease subsequent to the first calendar year a covered party meets or exceeds the compliance threshold in WAC 173-442-030(3).

(i) The GHG emission reduction pathway decreases annually by an additional one and seven tenths of a percent (1.7%) of the covered party's baseline GHG emissions value.

(ii) The additional one and seven tenths of a percent (1.7%) adjustment to a GHG emission reduction pathway does not apply to any calendar year that includes curtailment recognized by ecology.

(iii) Beginning in calendar year 2036, the emission reduction pathway remains constant at the value calculated for calendar year 2035.

(2) Ecology will issue a regulatory order as provided in WAC 173-442-200(6) to each covered party which contains:

(a) The GHG emission reduction pathway in units of MT CO2e for each calendar year in the compliance period; and

(b) The total reduction pathway for each compliance period.

(3) For EITE covered parties the GHG emission reduction pathway is determined per WAC 173-442-070.
