Overview

Stationary sources that hold an Air Contaminant Discharge Permit or Title V operating permit in Oregon are required to report greenhouse gas emissions to DEQ if the permit holder emits equal to or greater than 2,500 metric tons of carbon dioxide equivalent during the calendar year.

Starting with the reporting of 2023 emissions in 2024, permit holders must report GHG emissions data and related information through Your DEQ Online. Your DEQ Online is DEQ's new online file management system. The documents below provide more details on applicability, reporting requirements, and the use of our online reporting system.

Overview

Fuel suppliers and In-State Producers must report the greenhouse gas emissions resulting from the complete combustion of all fuels they supply for use in Oregon. While the Oregon greenhouse gas reporting rules apply to all Oregon licensed fuel sellers and dealers as well as any person that distributes more than 5,500 gallons of certain tax-exempt fuels (or 10,500 gallons of propane) the annual reporting obligation is limited to certain entities operating within the fuel distribution system.

Reporting requirements apply specifically to distributors that own and disburse fuel from Oregon terminal storage facilities, referred to as position holders, companies that produce fuel in-state and supply it for use in Oregon and certain distributors that import fuel from out of state.

Overview

An asset-controlling supplier (ACS) is an entity that owns or operates inter-connected electricity generating facilities or has exclusive rights to claim electricity from these facilities even though they do not own them. DEQ must approve a facility for ACS designation through the process described below. Entities reporting under Oregon's greenhouse gas reporting rules can report power from a DEQ-approved ACS as a specified source using a published system emission factor.

DEQ annually posts approved ACS and system emission factors below:

​ACS Approval Process

Entities seeking ACS designation must be approved through DEQ, as prescribed by OAR 340-215-0120. Suppliers must submit application materials, report data and comply with all third-party verification requirements under OAR 340-272. To start the process, review the materials below and email the Oregon DEQ Greenhouse Gas Program at GHGReport@deq.oregon.gov.

Renewal Process

To remain as an approved ACS under the Oregon GHG Reporting Program, an ACS must submit the application and data each calendar year.

Deadline

ACS applications and data must be submitted to DEQ by June 1 to be approved for use in a future year.​
