(Oregon) Administrative Rules Chapter 340 Division 215 (as amended in 2020)

Last updated: 30 April 2022

The Department of Environmental Quality issued the Oregon Administrative Rules Chapter 340 Division 215 in 2008, establishing the Oregon Greenhouse Gas Reporting Program. These rules govern the collection of annual greenhouse gas (GHG) emissions information from the state’s largest emitters.  


They require owners or operators of sources that emitted at least 2,500 MT CO2e during the previous year to register and annually report emissions. Any owner or operator of  a facility located in the state that contains petroleum and natural gas systems, as well as power generation systems must register and annually report in compliance with this division.  


Regulated entities are required to monitor emissions and submit emissions data reports each year by March 31. A separate emissions data report must be submitted for each sector and for each individual air contamination source, including facility name and location, date of submission, annual emissions of each GHG, and certification from a designated representative. 


For natural gas suppliers, fuel suppliers and in-state producers, the annual report must include a calculation of methane and nitrous oxide emissions. If there is a change of more than 5% in GHG emissions from the previous year, the regulated entity is required to provide a brief explanation of the cause. 


Regulated entities are further required to retain records sufficient to document and allow for verification of each report submitted and make such records available upon request. 


In 2020, Division 272 was established (applicable from 2022), requiring emissions reports submitted to the Department of Environmental Quality to be verified by independent third parties.
