Special thanks to our expert advisory panel, Anna‐Marie Cook, Sherri A. Mason, and Chelsea Rochman. Many participants in the Regional Monitoring Program for Water Quality in San Francisco Bay (RMP) made very helpful comments on the draft SAP including N. Arsem, M. Connor, M. Esparza, C. Sommers, L. Fono, and the Bay Area Clean Water Agencies. We also received comments from H. Allen and B. Robertson of USEPA, R. Fairey of Moss Landing Marine Labs, and Mark Banaszak Holl and Rachel Merzel of University of Michigan. Thanks to R. Holleman, D. Yee, P. Trowbridge, J. Davis and A. Malkassian of SFEI for their thoughtful review of earlier drafts. This report should be cited as: Sedlak M, Sutton R, Box C, Sun J and Lin D. 2017.

The category of ‘plastics’ is an umbrella term used to describe synthetic polymers made from either fossil fuels (petroleum) or biomass (cellulose) that come in a variety of compositions and with varying characteristics. These polymers are then mixed with different chemical compounds known as additives to achieve desired properties for the plastic’s intended use (OceanCare, 2015). Plastics as litter in the oceans was first reported in the early 1970s and thus has been accumulating for at least four decades, although when first reported the subject drew little attention and scientific studies focused on entanglements, ‘ghost fishing’, and ingestion (Andrady, 2011). Today, about 60-90% of all marine litter is plastic-based (McCarthy, 2017), with the total amount of plastic waste in the oceans expected to increase as plastic consumption also increases and there remains a lack of adequate reduce, reuse, recycle, and waste management tactics across the globe (GreenFacts, 2013).

AN INTRODUCTION TO THE PLASTIC POLLUTION MOVEMENT 4 What are microplastics, microparticles, and microfibers? 6 Why are microplastics a potential threat? 8 What are the pathways and sources of microplastics? 10 2. USING SCIENCE TO GUIDE ACTION 13 Development of this report 14 Use of this report 14 3. SAN FRANCISCO BAY MICROPLASTICS PROJECT FINDINGS 15 Rainy weather washes microplastics into Bay waters 15 Sediment in the lower south Bay had more microplastics 16 Prey fish consume fibers 18 High levels of rubbery fragments and other microplastics and microfibers found in stormwater 18 Wastewater samples dominated by microfibers 19 Quality control samples reveal microfibers are everywhere 20 Related Bay Area microplastics research 20 4. RECOMMENDATIONS FOR SAN FRANCISCO BAY 21 Recommendation #1: Support legislation that reduces single-use plastics and plastic packaging in the Bay Area and statewide 22 Recommendation #2: Explore green stormwater infrastructure management options to reduce microplastics from entering San Francisco Bay 24 Recommendation #3: Identify and prioritize intervention points for microfibers around filtration 26 Recommendation #4: Support the development of a San Francisco Bay Microplastics Management Strategy to reduce microplastics 28 Recommendation #5: Encourage textile industry to standardize methods to understand microfiber
