2 Climate Change Global Temperature Rise An increase in greenhouse gases (GHGs), methane, nitrous oxide, carbon dioxide and halocarbons Sea Level Rise Global average (USGS) 0.6mm-1mm per year East Coast of US rising 3-4 times faster Sea Level Rise in New England is at 2mm and 3.7mm per year over the past two decades

3 Goal 1 Develop a tool that will quantify the vulnerability of water and wastewater treatment facilities regulated by Mass DEP 1. Identify risk factors used in earlier study 2. Identify additional risk factors 3. Produce weights for each factor

4 Goal 2 Apply the finished tool to select facilities 1. Identify coastal facilities to test the tool 2. Gather data from application and package it in concise manner for stakeholders and officials to use as well as facility managers

5 Developing the Factors for Tool List of specific factors Too detailed/ specific Narrowed down to most significant for flood risk Left out environmental effects and combined sewer/ storm drain

6 Developing the Weights Most prominent addition to this tool Wastewater and drinking water specialists at Mass DEP Most important criteria identified first Location in FEMA and/ or ACE Zones Elevation of facility Then least important Elevation of storage tanks Membership to Mass WARN Weights can be adjusted

7 Wastewater Factors Weights Drinking Water Factors Weights FEMA Flood Zones* 16% 16% ACE Hurricane Inundation Zones* Elevation of Facility 15% Past Flooding* 8% Design flow vs. actual flow** 8% 7% Precautionary Protective Structures** Surface/Ground discharge 7% Longevity of backup power 5% Percent of processes that can run 5% Rainfall induced flow* 5% Presence of equalization basins 4% Member of Mass WARN 4% FEMA Flood Zones* 16% ACE Hurricane Inundation Zones* 16% Elevation of Facility 15% Surface or Ground Water (under/ not 10% under influence) Sources** Treatment processes 10% Past flooding* 8% Precautionary Protective Structures** 7% Onsite vs. Portable power 5% Longevity of power 5% Percent of processes that can run 5% Member of Mass WARN 2% Elevation of Storage Tanks** 1% * = Factors used by 2011 group ** = Factors suggested by 2011 group

9 Selecting the Facilities Originally 134 wastewater, 146 drinking water Sample of 25 wastewater, 25 drinking water Identified by stratified random sample Respondents: 23 wastewater, 14 drinking water

10 Application of the Tool Data provided by Mass DEP/ EPA GIS Surveys sent to each facility

11 Packaging the Risk Assessment Tool Present final tool in simple and useful form Providing stakeholders and officials with suggestions and recommendations
