Technical Advisory Committee 7 Pilot Project Study Area: Santa Ana Delhi Subwatershed Contributing City Areas(Acres) Santa Ana 6,828 Costa Mesa 2,648 County of Orange 636 Newport Beach 400 Irvine 126 8 Santa Ana-Delhi Diversion System with Trash Capture Features Coanda Screen Large Debris Screen Connection for Trash Boom 9 Project Goals OVERALL: Complete a model trash reduction project, based on collaborative multi-stakeholder plan, for adoption by other cities. Measure linkage between littering and pervasive single-use plastics captured by various BMPs Public outreach research on changing littering behaviors Promoting reduction of single-use plastics Determine if SAD Trash Capture Device is a viable trash capture approach for other flood control channels Find data patterns that reliably predict trash hot spots Stronger understanding of –Factors that determine hot spots and cold spots –Littering patterns and trash types at hot spots 10 How Does This Project Benefit Other Cities? Would provide policy basis for reducing litter through source control approaches, rather than adopting product ban ordinances Regional trash capture devices could reduce future compliance costs, if determined to be effective Verified trash generation rate model has multiple benefits for cities developing trash compliance implementation plan 25 of 35 stormwater program agencies (cities and County) interested in creating OC specific trash generation rate model 11 Example of Project Results for Focus Campaign Purposes Annual trash load generated 95% 5% Annual Trash Load Captured Not Captured 60% 35% 5% All Trash Captured Single Use Plastics Captured Not Captured 12 Why Focus on Trash? Serious global issue Every ocean has a trash gyre Numerous marine life plastic ingestion studies 50%-80% of marine debris (ocean trash) is land based plastic Plastic can persistent for up to 600 years Very important local issue Beaches are significant economic driver Newport Bay has economic and ecological value Less trash to remove means more funding for other public services Henderson Island, Pitcairn Islands 3,200 miles to nearest continent 13 Why Focus on Trash in Newport Bay? Newport Bay Trash Boom 14 2015 Trash Policy Applicable to City of Newport Beach April 7, 2015 SWRCB adopted new statewide regulation for trash control Final Trash Provisions of the Water Quality Control Plan for Inland Surface Waters, Enclosed Bays, and Estuaries (ISWEBE) of California section will be applicable to City of Anaheim Santa Ana Regional Board expected to issue administrative enrollment letter by June 2, 2017 15 Compliance Pathways City required to select an implementation track: Track 1: Install and maintain full capture system (FCS) devices within PLUs. OR Track 2: Implement and maintain any combination of controls at PLUs that provides full capture system equivalency (FCSE). 16 How City Intends to Comply with the Trash Provisions Policy Purchase and install full capture systems Connector Pipe Screens 17 Hydrodynamic Separators In-line storm drain capture system In-Line Trash Screens Gross solids removal devices Part of SAD Trash Capture Device Purchase and install full capture systems How City Intends to Comply with the Trash Provisions Policy 18 How Much Will Compliance Cost? Annual costs to keep streets, storm drains, and flood channels trash free 2016-2017 approximate O&M costs $5,698,300 Newport Bay Watershed $665,024 Santa Ana Delhi subwatershed Cities must achieve compliance by 10 years of first implementing permit $56,983,000 plus annual O&M costs for new trash capture devices 19 Santa Clara Valley Urban Runoff Pollution Prevention Program.
