Quality Assurance Project Plan for Urban Waters Investigation of PCBs in Soils and Stormwater Associated with Demolition Activities

The Draft “Quality Assurance Project Plan for Urban Waters Investigation of PCBs in Soils and Stormwater Associated with Demolition Activities”  is now available for review.

The objective of this study is to evaluate the potential for PCBs in building materials to impact soil and stormwater. This project involves testing soil samples prior to and following demolition activities of target properties to identify the effectiveness of current demolition practices. Stormwater will also be tested from a selected number of stormwater conveyances in the located in the study area and compared with results from previous Urban Waters studies for the purposes of trend evaluation.

The results of this study will help inform development of Best Management Practices for managing PCBs in building materials, which is Control Action 5.13 in the 2016 Comprehensive Plan to Reduce Polychlorinated Biphenyls (PCBs) in the Spokane River.

This study is being conducted by Ecology’s Urban Waters program. Because of a tight weather window and staff schedules we will be unable to make major changes to the scope of the project.

Please provide comments or questions to Adriane Borgias via email at ABOR461@ecy.wa.gov before February 28th, 2017.

Date: September 29th
Time: 2:00 p.m.

Since the last Spokane River fish advisory was updated, new methodologies are being used to calculate human health risk for additive exposure to PCBs and other chemicals following similar biological pathways. Further, Washington State is considering changes to toxics criteria for human health based on fish consumption. These changes are of importance to stakeholder discussions regarding reduction of toxics in the Spokane River.

As shown in attached agenda, Dave McBride from Washington Department of Health will review and discuss these issues with interested stakeholders. Representatives from the Urban Waters Initiative and other local experts will help participants understand the potential impact of these policies on assessing Spokane River needs.
