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
