World Trade Center Diesel Emission R duction Project Proposed Project Outline January 14, 2002

Primary Project Participants: NYS Department of Environmental Conservation US EPA Region II US EPA Headquarters NESCAUM

Background This memo outlines a plan to control diesel emissions from vehicles and machines working at the World Trade Center (WTC) recoveiy/demolition and rebuilding site. The recovery effort associated with the September 11 terrorist attacks are having a profound effect on the air quality in the neighborhoods surrounding the area. The equipment and vehicles used in the recovery and cleanup effort arc powered by diesel fuel. Diesel exhaust is associated with adverse health effects and has been designated a carcinogen by the U.S. EPA. As the fires and dust associated with the recovery/demolition of the WTC site subside, emissions from diesel equipment and vehicles working at the site will be the largest source of pollution in the area. Given the negative health and welfare effects associated with exposure to diesel exhaust, there is a pressing need for the mitigation of emissions from the equipment in the recovery and rebuilding effort. Project Goal

The goal of the project is to reduce emissions from diesel equipment and vehicles working at the World Trade Center site without hindering the clean up effort or performance of the engines. The proposed methods to achieve this goal are the use of ultra low sulfur diesel fuel (<30 ppm) in both highway and nonroad engines and the retrofitting of machines and vehicles with emission control devices.

Project Approach

Project participants propose to reduce emissions in two phases. Ph-’'< J will begin immediately with: 1) an inventory of equipment and vehicles on site; 2) a switch from 500 ppm diesel fuel to ultra low sulfur fuel fc" city operated vehicles; 3) retrofitting of city operated vehicles where possible; and 4) clean fueling and retrofitting of privately operated vehicles and/or machines.'^
