Item No. 8a_supp Date of Meeting April 14, 2020 Renewable Natural Gas Supply Contract Authorization Environment & Sustainability Facilities & Infrastructure 1 Presentation Overview 1. Review Port climate goals 2. How Renewable Natural Gas (RNG) supports climate goals 3. Why RNG is heeded now 4. Proposed Action Contract Principles - Budget 2 The Port's Climate Goals Reduce Port-owned and controlled (Scope 1 &2) greenhouse gas emissions below 2005 levels by: . 15% by 2020 . 50% by 2030 . 100% by 2050 3 The Port's GHG Emissions 2018 Port-wide Scope 1 & 2 Greenhouse Gas Emissions 30000 25000 15%' 0, g m Liquid Fuels o $ 15000 m Electricity Cc 50%50% 5 m Natural Gas 10000 Ss 5000 4 CA Goal = 50% by 2030 5 CA Goal = 50% by 2030 6 What is Renewable Natural Gas (RNG)? A zero carbon natural gas alternative. As organic waste breaks down, it emits methane gas that can be captured and processed to meet natural gas pipeline quality specifications. RNG Sources: ~100 production facilities nationwide * 70% are landfills; 30% wastewater treatment & anaerobic digesters * 90%of these facilities used for transportation fuel (i.e. CNG fleets) 7 Cedar Hills Landfill, King County Renton WWTP, King County Bar-Way Farm, Massachusetts 8 9 | J or > a - f ny beesey 3 g - } < oo a Co' ne i"_ , _ - rm aa = 4 > : n >: - : . ; 2 a - ho c = ) on - go : or > - .

Limitations of Translatable Documents
PDF files are created with text and images are placed at an exact position on a page of a fixed size.
Web pages are fluid in nature, and the exact positioning of PDF text creates presentation problems.
PDFs that are full page graphics, or scanned pages are generally unable to be made accessible, In these cases, viewing whatever plain text could be extracted is the only alternative.
