ENVIRONMENTAL DATA COLLECTION AND EVALUATION METHODOLOGY Scope and Purpose

readily available environmental database references to identify and evaluate listed hazardous/contaminated locations that may pose potential risks to site development within the study corridor.1 The study corridor is defined as 1,000 feet in width as measured 500 feet on each side of the Danbury Branch rail right-of-way centerline from South Norwalk station to New Milford center. The objective of environmental data collection and evaluation is to determine the relative environmental risk associated with land uses in the vicinity of the alternatives being considered in the study corridor in order to estimate the likelihood for each study alternative to encounter discharge, spillage, uncontrolled loss, seepage, or filtration of hazardous wastes, contaminated materials, or other regulated substances
