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
