Supplemental Environmental Projects

DEQ’s Office of Compliance and Enforcement assesses civil penalties for environmental law violations. Violators sometimes may offset a portion of their monetary penalty by agreeing to pay for a supplemental environmental project. The project can represent up to 80 percent of the total penalty amount. These projects must improve Oregon’s environment in some way, and are not available in all cases. DEQ must approve all projects. From 2012 through 2014, DEQ approved 74 projects valued at approximately $1.14 million.
To obtain an application for a supplemental environmental project, see SEP Application or call DEQ’s Office of Compliance and Enforcement, Portland, at 503-229-5340, or call toll-free in Oregon at 1-800-452-4011, x5340.

Environmental law violators can help offset their penalties by electing to pay for a project that improves the environment.

Qualifying for a Supplemental Environmental Project


In order to qualify for a supplement environmental project:

  • The project must primarily benefit the environment or public health in Oregon.
  • As much money must be spent on the project as is sought in the penalty reduction.
  • The project cannot be an activity or result that is already required by law or set to become a future requirement.
  • The portion of the project attributable to penalty reduction is not funded by government contracts, loans or grants.
  • The project does not create a significant market or economic advantage for the violator.
  • The project does not result in DEQ controlling the funds or implementing the project.
  • If the violator is doing the project itself, the project must be commensurate with the violator’s expertise and capabilities.
  • The violator must provide a final report on the project.

Recent Examples of Supplemental Projects

  • The city of Portland is funding projects valued at more than $500,000 to settle a penalty stemming from sewage discharges that occurred between 2001 and 2007. The projects include: restoration of a portion of Errol Creek basin in southeast Portland’s Johnson Creek watershed; retrofitting of the Cathedral Park boat ramp parking lot for improved stormwater management in north Portland; and construction of several water quality swales in the Fanno Creek basin area of southwest Portland to help filter polluted water that runs off nearby roads, lawns and other areas.
  • The city of Sheridan, penalized for a wastewater discharge permit violation, contributed $3,600 of a $4,500 penalty to the Yamhill Basin Council for a streamside restoration project on the South Yamhill River.  The project will reduce stream erosion and provide shade for cooler water temperatures that benefit native trout. The project, which has a total cost of $7,000, is to be completed in spring 2010.
  • LDN Construction contributed $5,280 of a $6,600 civil penalty to Cascade Sierra Solutions to assist independent owners and operators to upgrade their semi-trucks to clean diesel technology, greatly reducing diesel particulate and greenhouse gas emissions.
