HART have used the platform to facilitate tracking of real property ;�W � .' transactions,cultural and historic resources,permits,and 1 .} environmental incident tracking along the rail corridor. J .a To provide greater access to HART and other city employees without the need for individual licensing or Jacobs proprietary software,the ArcGIS platform was migrated to and is currently •" hosted on the City and County of Honolulu's Department of Information Technology(DIT)web servers. Hazardous Materials Reporting Hundreds of environmental sites processed and evaluated along the City Center rail corridor. We developed streamlined release reporting forms to facilitate consistent and efficient preparation of release reports.We Within the 5-mile city center section of the corridor,our team has prepared and submitted over 200 release notification reports to been performing site reconnaissance inspections of up to 100 HDOH.We also prepared numerous other reports including properties and their surroundings,approximately every 180 days. environmental summaries,technical memoranda,investigation This includes thousands of publicly available environmental remediation,and waste characterization reports. records with hundreds of known or suspected contaminated sites, Development of Programmatic Environmental Hazard underground and overhead utilities,and many potential Evaluation and Environmental Hazard Management Plan recognized environmental conditions. (EHE/EHMP) The project was configured as a large-scale,centralized data We worked closely with HART and HDOH to prepare the existing processing and analysis task with the goal of automating as many Programmatic EHE/EHMP for HART in support of the HRTP.This components as possible. Federal,state,and regulatory agency programmatic document presented the environmental hazards files from EDR were processed and reviewed together with along the rail guideway corridor and explains how to properly environmental information readily available from both HDOH and manage contaminated materials from existing environmental HART environmental databases. Environmental datasets are conditions in accordance with applicable laws and regulations. batch-processed to determine distance,direction,and hydraulic Through negotiation with the HDOH Hazard Evaluation and flow relationship with each individual subject property.

Each difficulties and costly delays.The Programmatic EHMP is also a delivery iteration brought increased efficiencies while maintaining functional document that identifies strategies for identifying quality throughout,resulting in the successful delivery of over reporting,and managing contaminated media during construction 250 individual environmental reports to date. During each cycle, so that work could continue in most cases without the need for over 1,200 environmental records are being uploaded to our extensive stop work, reporting,and development and HDOH central database for regulatory status evaluation.

Phase I ESAs.and Phase II ESAs based on distance,direction,and ASTM screening criteria, We performed environmental due diligence for 272 properties resulting in a dataset of approximately 12,000 records that are proposed for acquisition and completed and kept up to date evaluated against spatial and environmental criteria(e.g., Phase I ESAs for 112 properties along the rail guideway corridor. distance,hydraulic position, nature of potential release,substance The due diligence and Phase I ESAs are performed in accordance mobility,and similar)to determine the likelihood to affect a with the All Appropriate Inquiries rule and standards set forth in subject property for each site.Based on the environmental ASTM 1527-13 for parcel acquisitions prior to construction of the records evaluation and the results of site reconnaissance and HRTP. interviews,each property is assigned an environmental concern level to identify those with a higher environmental concern and Jacobs STANDARD FORM 330(REV.7/2021)123 TRACKING#:0063f000009AVJNAA4
