(1) To demonstrate compliance with the emission reduction requirement, each petroleum refinery must use monitoring measures that satisfy requirements for petroleum refinery owners/operators reporting greenhouse gas emissions to EPA under 40 C.F.R. Part 98. Unless additional monitoring is required by the credit order issued under WAC 173-485-060 (2)(c), the 40 C.F.R. Part 98 monitoring is considered sufficient for quantifying annual emissions for this regulation.

(2) The permitting authority may require additional monitoring, recordkeeping, and reporting to document compliance with a credit established through this regulation. The additional monitoring, recordkeeping, and reporting must be identified in the credit order issued under WAC 173-485-060 (2)(c).
