Covanta Marion, Inc.

Cleaner Air Oregon is a health-based permitting program that regulates emissions of toxic air contaminants from facilities based on risk to nearby communities. CAO requires facilities to report toxic air contaminant emissions, assess potential health risks to people nearby and reduce toxic air contaminant risk if it exceeds health standards.

As part of the Cleaner Air Oregon process, each facility has a dedicated web page to provide communities access to facility information and updates on where it is involved in the process.

  • Each step of the CAO risk assessment process has a section that includes DEQ's communications and deliverables from the facility.
  • A color-coded graphic shows where a facility is in the Cleaner Air Oregon Process.
  • For additional information and history of the program, visit the Cleaner Air Oregon website.

​​For an introduction to emissions inventories and why they matter, please see EPA's Fact Sheet. An Emissions Inventory is a list of each toxic air contaminant regulated under the Cleaner Air Oregon rules that a facility emits in a given year. The Emissions Inventory includes the amount of each toxic air contaminant emitted from each individual emissions-producing activity.

About the facility

Covanta Marion, Inc. owns and operates a solid waste-to-energy facility in Brooks, Oregon. Construction approval for the facility was issued by DEQ in 1983 and the facility began operations in 1986. The primary objective of the CMI facility is to provide for the disposal of solid waste. In order to achieve this primary objective the facility receives, stores, and combusts solid waste as defined in Oregon Revised Statues 459.005 and the facility’s solid waste permit. The combustible fraction of the solid waste is utilized to produce steam, which is in turn utilized in a turbine generator to produce electricity which is sold to the local utility. The facility operates 24 hours per day, 365 days per year, except for periods of scheduled and unscheduled maintenance.
