Stormwater Resources

Conducting a stormwater evaluation

• Guidance for Evaluating the Stormwater Pathway at Upland Sites
  Guidance for Cleanup Project Managers including Appendices designed to provide Responsible Parties with clear directions for developing stormwater assessment workplans and reports.
• Framework for Portland Harbor Stormwater Screening Evaluations
  Appendix D of the EPA-DEQ Joint Source Control Strategy. Describes the approach for evaluating the stormwater pathway at Portland Harbor sites. The guidance document above is consistent with this Framework and provides more detailed instructions for implementing an evaluation.
  

Sampling guidelines

• Lower Willamette Group Field Sampling Plan
  This FSP and Quality Assurance Project Plan presents the approach and procedures to implement stormwater activities undertaken by the Lower Willamette Group in 2007.
• Lower Willamette Group Field Sampling Plan
• Quality Assurance Project Plan
• Guidance for Sampling of Catch Basin Solids
  Developed by the City of Portland. Describes standard procedures for collecting solids (sediments) from stormwater catch basins.
• WDOE Stormwater Sampling Guidance
  Developed by the Washington Department of Ecology. Describes standard procedures for sampling stormwater.
• Characterizing and Managing Catch Basin and In-line Sediments
  DEQ's expectations regarding sampling and management of sediments removed from stormwater catch basins or the stormwater conveyances system as part of a Portland Harbor stormwater evaluation.
  

Portland Harbor pollutants

• Table 3.1 from Joint Source Control Strategy
  Joint Source Control Strategy screening level values for soil, stormwater sediment, stormwater, groundwater and surface water.
• Potential PCB Source Fact Sheet
  Types of industries, practices, and products that might be potential sources of polychlorinated biphenyls (PCBs).
  

Best management practices and other resources

• Catch Basins Fact Sheet
  Catch basin design, effectiveness and sediment sampling.
• Environmentally Responsible Best Management Practices
  Basic maintenance practices for stormwater catch basins.
• International Stormwater Best Management Practices Database
  Technical documents, software and database aimed at providing scientifically sound information to improve the design, selection and performance of BMPs. The project, which began in 1996 under a cooperative agreement between the American Society of Civil Engineers and the U.S. Environmental Protection Agency, has support and funding from a broad coalition of partners including the Water Environment Research Foundation, ASCE Environmental and Water Resources Institute, USEPA, Federal Highway Administration and the American Public Works Association.
