Metro Centroid Tonnage Goals Presentation to SWMCB May 27, 2009

Background Presented data analysis and sample WARM run to SWMCB on April 22 MPCA is identifying possible targets and their resulting GHG reduction potential for stakeholder work group MPCA will be presenting this information to stakeholder group on May 28 Stakeholder group will discuss and suggest targets for each centroid Summer centroid input work

Purpose and Objectives Establish a starting point for work group to discuss goals for centroids Provide initial analysis of GHG reduction potential by centroid Continue to refine WARM modeling work and understand its capabilities

GHG Reduction Targets by Centroid (based on waste generation) Duluth Centroid 3.3 MMTCO 2 e (6.3%) Rochester Centroid 2 MMTCO 2 e (3.8%) St. Cloud Centroid 3.7 MMTCO 2 e (7.0%) Metro Centroid 43.5 MMTCO 2 e (82.9%) Target GHG Emissions Reduction for all Centroids (70% of MCCAG Target) = 52.5 MMTCO 2 e

Metro Business As Usual Recycling rate held steady, therefore, 2025 rate is 39% Organics rate held steady, therefore, 2025 rate is 3% WTE tonnages held steady, and no capacity is added; therefore, 2025 rate is 25% Landfilling rate becomes 32% in 2025

Metro Centroid Annual GHG Reduction (9,500,000) (8,500,000) (7,500,000) (6,500,000) (5,500,000) (4,500,000) Metric Tons Carbon Dioxide Equivalents BaselineTarget Scenario Cumulative GHG Reduction = 20,603,000 metric tons of CO2 equivalents

Metro WARM Results Metros Goal (i.e. its share of 52.5 MMTCO 2 E) = 43.5 MMTCO 2 E Cumulative GHG reduction for this scenario = 20.6 MMTCO 2 E
