Exposition Metro Line Construction Authority Exposition Corridor Transit Project Phase 2 Final Environmental Impact Report Technical Background Report FINAL Hazards and Hazardous Materials December 2009 Prepared for: Exposition Metro Line Construction Authority By: ERRATA The Exposition Metro Line Construction Authority (Expo Authority) has determined that the bike path and Second Street Santa Monica Terminus are no longer under consideration as part of the Expo Phase 2 Light-Rail Transit project. This Technical Background Report was drafted prior to the final definition of the LRT Alternatives that was presented in the Draft Environmental Impact Report (DEIR). Accordingly, discussion of the bike path and Second Street Santa Monica Terminus still remain in this report but no longer apply and should be disregarded.

INTRODUCTION 1.1 Overview This report describes the potential adverse impacts on human health and the environment due to exposure to hazardous materials or conditions that could be encountered as a result of implementation of the proposed Exposition Corridor Transit Project Phase 2 (Expo Phase 2). Hazardous materials include, but are not necessarily limited to, solvents, mercury, lead, asbestos, fuels, oils, paints, cleansers, and pesticides that are used in activities such as construction activities or building or grounds maintenance. Potential effects include those associated with exposure to hazardous materials used, stored, transported, or disposed of during construction activities or proposed project operations. Potential water quality effects from runoff that could contain hazardous or polluted materials during construction or operational activities
