The goal of this study is to evaluate environmental assessment strategies for the tire contaminant, 6PPD-quinone (6PPD-q) to support ongoing urban watershed and salmon recovery planning. Understanding the occurrence and persistence of 6PPD-q to salmon bearing streams will help prioritize urban watershed remediation projects. Remediation projects that require baseline data include stormwater retrofits, fish barrier removals, floodplain projects, sustainable urban and transportation planning, and conservation efforts.
The proposed 6PPD-q environmental assessment strategies incorporate three main approaches:
- Opportunistic studies to understand the spatial occurrence and persistence of 6PPD-q with variable watershed characteristics.
- Salmon in urban watersheds bioassay studies to develop and re-evaluate methods for measuring the health of salmon-bearing streams.
- Focused studies to address the many data gaps around how and where to measure 6PPD-q in the environment (method development).

6PPD Legislative Report 2022
A 6PPD spatial technical advisory committee shared research updates and priority data gaps to help develop strategies to guide our understanding of the scope and scale of the newly identified 6PPD-quinone in the environment. The committee is a multi-disciplinary team that includes natural resource scientists and managers from tribal, federal and state agencies, non-profits, consultants and PSEMP working groups. A summary of recommendations and current knowledge is now available in a 6PPD Legislative Report. This process of evaluating the current knowledge regarding the impact of tire contaminants on aquatic life helped galnanize a pro-active state, tribal and federal working groups to address the 6PPD problem and secured short-term funding for further investigations.
