- Building a Water Quality Trading Program: Options and Considerations — Willamette Partnership: National Network on Water Quality Trading (WQT). Created by the National Network on Water Quality Trading through the Willamette Partnership this document aims to provide a reference on common elements and decisions inherent in water quality trading (WQT) program design (especially point-nonpoint WQT programs) and the range of available options. The information in this document is intended to make it easier to establish WQT programs, provide greater transparency about what WQT programs can accomplish, and help WQT program developers meet their clean water goals.

- The Metals Translator: Guidance for Calculating a Total Recoverable Permit Limit from a Dissolved Criterion, EPA 1996 — The metals translator is a tool for environmental scientists and permit writers to use in calculating the amount of metal that may be discharged from a facility to a surface water body based on how the metal is distributed (partitioned) between water and sediments in the receiving stream. This technical guidance explains how the translator is used in setting limits on the amount of a metal that can be discharged in both simple and complex situations involving single dischargers or multiple dischargers, and still protect aquatic life. The guidance discusses how these translators can be developed for specific water bodies to reflect various naturally occurring circumstances. It also includes information on clean sampling and analytical procedures that the user may elect to follow.
- Natural Treatment Systems: A Match for Oregon’s Cities and Towns — ACWA/DEQ, 7/2014. This report inventories a variety of natural treatment systems being used in Oregon including tree farms, wetlands, indirect discharge, and water quality trading. Pollutant removal characteristics and siting considerations are summarized.
- Oregon’s Air Toxics – A Situation to Watch, 6/2016 Presentation from Don Caniparoli, CH2M
- Oregon DEQ – Water Quality Permit Search — Searchable database for water quality-related permits, permit fact sheets, evaluation reports, and other information. All individual National Pollutant Discharge Elimination System (NPDES) permit-related documents are available for viewing. Many Water Pollution Control Facilities (WPCF) permit documents are also available.
- Oregon DEQ – Total Daily Maximum Loads (TMDLs) Program – This site contains links to Total Maximum Daily Load (TMDL) and Water Quality Management Plan (WQMP) documents prepared for waterbodies in Oregon designated as water quality limited on the 303(d) list.
- Oregon Integrated Water Resources Strategy — The Oregon Water Resources Commission — The Oregon Water Resources Commission adopted the state’s first Integrated Water Resources Strategy in August 2012. The Strategy provides a blueprint to help the state better understand and meet its instream and out-of-stream needs, taking into account water quantity, water quality, and ecosystem needs.
- PCBs in Municipal Products, City of Spokane, 3/2015 — Many products can easily come into contact with rainwater and contribute to PCB concentrations in stormwater runoff. Municipalities are concerned about the presence of PCBs in commonly used products such as road paint, asphalt sealers, pesticides, and de-icer, to name a few. However, limited data is available as to the concentration of PCBs in products used for road and facility maintenance. Nearly 50 product samples were collected and analyzed for PCBs using EPA Method 1668C. This method is capable of detecting low concentrations of PCBs for all 209 congeners. The majority of samples were composed of roadway, pipe, and vehicle maintenance products. Because PCBs are also ubiquitously detected in sanitary wastewater samples, five personal care products were sampled as well.
- Peracetic Acid for Wastewater Effluent Disinfection-Ti-City WPCP PAA Pilot Project — (10/2015) (part 1) (part 2)
Presentation from Dale Richwine, Richwine Environmental, and information concerning the use of peracetic acid for wastewater effluent disinfection.
- Phthalates: Environmental Health Issues & Reduction Strategies, 4/2016 — Presentation from Kevin Masterson, DEQ
- Potential Use of Aquifer Storage (and Recovery) as a Tool for Stormwater Management and Stream Restoration — Jason Melady, GSI Water Solutions (PDF)Aquifer Storage and Recovery (ASR) is a water storage and management technique that has primarily been used by municipalities to store, in some cases, hundreds of millions of gallons of drinking water underground during off-peak periods for recovery and use during high demand periods. Based on the successful utilization of ASR for municipal drinking water storage, alternative concepts utilizing the storage technology for other purposes are emerging, including for irrigation, streamflow enhancement and restoration, thermal mitigation, and stormwater management. This presentation, from the 2015 ACWA Stormwater Summit, explores these alternative groundwater recharge concepts and their potential use for wastewater and stormwater management.
- Temperature Compliance Guidance Manual Workshop – June 1, 2017. Presentations and materials are posted on the Conferences and Workshop page.
- Treatment Technology Review and Assessment HDR 12/2014 – HDR Engineering completed a review of the impact of revised human health-related toxic water quality standards on NPDES permit holders. The report evaluates the available technology and costs to meet toxic water quality standards similar to Oregon’s. The report concludes that there are limited ‘proven’ technologies to meet discharge standards this low, and that the types of advanced treatment needed to meet the standards could increase the capital cost of wastewater treatment by $17 to $29 per gallon per day of capacity, with associated high energy consumption, increased greenhouse gas production, increased solids production, and increased footprint requirements. The report was completed for the Association of Washington Business.
- Toxics in Oregon’s Waters – Statewide Assessment, 8/2015 — Presentation from Lori Pillsbury, DEQ

- Willamette River Point-Source Heat Trading Tool (USGS) — The Willamette River Point-Source Heat-Trading Tool allows a user to increase or decrease the heating signature of each source and thereby evaluate the effects of a wide range of potential point-source heat trades. By simply selecting a target time period and modifying the strength factors associated with each point source in an iterative fashion, potential trades can be defined and the effects on the temperature of the river can be estimated.
