S&W will <br />be responsible for planning, managing, performing, and documenting a Hazardous Material <br />Analysis Report (HMAR) and a Remedial Cost Estimate (RCE). The HMAR, in combination with <br />the RCE (detailed in the next subsection) will meet WSDOT’s Discipline Report requirements. <br />Hazardous Material Analysis Report <br />An HMAR will be completed to evaluate potential hazardous materials/contamination issues or <br />conditions that may impact the North Broadway Pedestrian Bridge project. The HMAR will be <br />used by project team members (other than S&W) to evaluate pedestrian bridge concepts during <br />the alternatives analysis (in Task 1.06). <br />S&W will identify properties in and around the preferred crossing footprint (between Liberty Hall <br />and the Cascade Learning Resource Center [CAS]) where current and/or past property uses <br />may have resulted in hazardous materials contamination. The study corridor for the HMAR is <br />from 10th Street to the entrance of the parking lot on the northeast side of Liberty Hall (an <br />approximately 450-foot span). For this subtask, S&W will: <br />· Review historical-use information records for properties along the study corridor. Such <br />information could include previous land use(s) or other activities that could have led to <br />the presence of hazardous materials (e.g., petroleum products) in the environment. <br />Sources of information may include aerial photographs and insurance maps (e.g., <br />Sanborn maps). The actual sources available for a given study will vary and may include <br />sources not listed in this task. We will reference the actual sources used in the HMAR <br />report. <br />· Obtain and review records that will help identify potential contamination in connection <br />with the properties. Standard federal and state databases will be reviewed for properties <br />within 1/3-mile of the study corridor. Federal agency lists to be reviewed include the <br />following: <br />o National Priorities List (NPL) sites; <br />o Comprehensive Environmental Response, Compensation, and Liability <br />Information System (CERCLIS) sites; <br />o Resource Conservation and Recovery Act (RCRA) generators; and <br />o Emergency Response Notification System sites. <br />· Washington State Department of Ecology lists to be reviewed include the following: <br />o Hazardous Sites List; <br />o Confirmed and Suspected Contaminated Sites List (CSCSL); <br />o Landfill and/or solid waste disposal sites; and
