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 Centroid3.3 MMTCO2e (6.3%)
Rochester Centroid
2 MMTCO2e (3.8%)
St. Cloud Centroid 3.7 MMTCO2e (7.0%)
Metro Centroid43.5 MMTCO2e (82.9%)
Target GHG Emissions Reduction for all Centroids (70% of MCCAG Target) = 52.5 MMTCO2e

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

Baseline Target Scenario
Cumulative GHG Reduction
= 20,603,000 metric tons of CO2 equivalents
Metro WARM Results
Metro’s Goal (i.e. its share of 52.5 MMTCO2E) = 43.5 MMTCO2E
Cumulative GHG reduction for this scenario = 20.6 MMTCO2E
