Greenhouse Gas Reporting Protocols

Current News

As of February 7, 2012, DEQ is proposing changes to the Oregon greenhouse gas reporting protocols to harmonize emissions categories reported to Oregon’s program with categories reported to EPA's federal reporting program. DEQ is also proposing to extend Oregon’s supporting documentation provisions designed to protect sensitive business information. Details on the proposed changes and how to comment are provided in the following pages for affected facility categories, including air quality permit holders and landfills.

DEQ is still developing protocols for consumer owned utilities and gasoline, diesel and aircraft fuel distributors. Reports will be due no earlier than 30 days after DEQ finalizes the protocols.

Greenhouse Gas Reporting Protocols

Oregon rules require certain facilities to report their annual greenhouse gas emissions to DEQ using DEQ-approved protocols. Click on each facility type below to learn about who needs to report within each facility category, reporting deadlines and the methodologies facilities must use to calculate and report emissions.

Facilities required to report greenhouse gas emissions to DEQ:

• Facilities emitting 2,500 metric tons or more of carbon dioxide equivalent during a year, including
• Air quality permit holders (in Oregon's ACDP and Title V programs)
• Landfills
• Wastewater treatment facilities¹
  
  
• Suppliers of fuels and electricity, including
• Gasoline, diesel and aircraft fuel distributors²
• Propane wholesalers
• Natural gas suppliers
• Investor owned utilities and electricity service suppliers
• Consumer owned utilities³

¹DEQ is temporarily deferring reporting from wastewater treatment facilities.
²These protocols are not yet approved.
³DEQ will publish reporting protocols for consumer owned utilities in 2012. The reporting deadline will be extended to provide at least 30 days following publication of these protocols.

If you have questions, email the greenhouse gas program or call Andrea Curtis at 503-229-6866 or Colin McConnaha at 503-229-5094 (toll-free in Oregon 800-452-4011).

Relationship to Federal Greenhouse Gas Reporting Requirements

40 CFR. Part 98 requires large facilities and suppliers of greenhouse gas emissions in the United States to report those emissions to EPA. EPA's reporting program applies to facilities emitting 25,000 metric tons or more of carbon dioxide equivalent during a year.

Facilities required to report greenhouse gas emissions to EPA that are also subject to Oregon's reporting requirements must report greenhouse gas emissions to DEQ. DEQ has taken measures to simplify reporting for facilities subject to both the Oregon and federal requirements and avoid duplicative reporting wherever possible. Oregon rules allow a facility to provide DEQ with a copy of its report submitted to EPA in place of reporting separately to DEQ. However, Oregon rules authorize DEQ to require the submission of additional information in cases where the copy of the EPA report is not sufficient to verify and evaluate greenhouse gas emissions and related information. See DEQ-approved reporting protocols (above) for each facility category for more information.
