Chapter 173-441 - Reporting of emissions of greenhouse gases
Section 173-441-120 - Calculation methods for facilities
Current through Register Vol. 24-06, March 15, 2024
This section establishes the scope of reportable GHG emissions under this chapter and GHG emissions calculation methods for facilities. Owners and operators of facilities must follow the requirements of this section to determine if they are required to report under WAC 173-441-030(1). Owners and operators of facilities that are subject to this chapter must follow the requirements of this section and all subparts of 40 C.F.R. Part 98 listed in Table 120-1 of this section when calculating emissions. If a conflict exists between a provision in WAC 173-441-010 through 173-441-110 and 173-441-140 through 173-441-170 and any applicable provision of this section, the requirements of those sections must take precedence.
(1) Source categories and calculation methods for facilities. An owner or operator of a facility subject to the requirements of this chapter must report GHG emissions, including GHG emissions from bio-mass, from all applicable source categories in Washington state listed in Table 120-1 of this section using the methods incorporated by reference in Table 120-1. Table 120-1 and subsection (2) of this section list modifications and exceptions to calculation methods adopted by reference in this section.

(3) Calculation methods for voluntary reporting. GHG emissions reported voluntarily under WAC 173-441-030 ( ) (5) must be calculated using the following methods:
(4) Alternative calculation methods approved by petition. An owner or operator may petition ecology to use calculation methods other than those specified in Table 120-1 of this section to calculate its facility GHG emissions. Such alternative calculation methods must be approved by ecology prior to reporting and must meet the requirements of WAC 173-441-140.
(5) Emissions subject to reporting, but not subject to the reporting threshold. Facilities that supply CO2 as described in WAC 173-441-122(3)(b) required to report or voluntarily reporting under WAC 173-441-030(1) or (5) based on GHG emissions calculated under subsections (1) through (4) of this section must report supplied CO2 using the 40 C.F.R. Part 98 Subpart PP methods described in WAC 173-441-122(3)(b) as part of their facility report as described in that section regardless of the amount of GHG emissions. Those emissions do not count towards the reporting threshold in WAC 173-441-030(1).
