Hazardous Material Commodity Transportation Flow Study

State of Connecticut Statewide Study

Services: Emergency Planning & Response
Client Served: Government

Loureiro was retained by the Connecticut Department of Energy & Environmental Protection (CTDEEP) to conduct a Hazardous Materials Commodity Transportation Flow (HMCTF) study for the State Emergency Response Commission (SERC) to evaluate the volume and nature of hazardous materials movements into, out of, and through the five Department of Emergency Management and Homeland Security (DEMHS) regions.

The types of hazardous commodity transportation considered in this study were air cargo, marine vessel shipments, rail carloads, and hazardous pipelines. The purpose of the HMCTF study was to provide a tool for the SERC, Local Emergency Planning Committees, and local jurisdictions to plan for and respond to the potential risks associated with hazardous materials transported to or through the five DEMHS regions and the waters of the Long Island Sound.

The scope of the study required the review of public and private Connecticut airports (including crop dusting planes), the ports of New Haven Harbor, Bridgeport Harbor, and New London Harbor, railroads operating in the state, and natural gas and petroleum pipelines. The study used data from various companies, organizations and agencies; and Loureiro referenced the data collected as part of the three HMCTF studies performed in 2009 and 2010 that focused on road transportation of hazardous commodities. The data was compiled to provide a clear picture of the type and amounts of various hazardous commodities moving throughout the state of Connecticut.


  • Provided a summary of the average annual volume for all hazardous commodities shipped by means of rail, marine vessel, and air throughout Connecticut
  • Summarized the top hazard class by percent for the hazardous commodities shipped for each DEMHS Region.
