Site Feasibility Analysis Bronx North Yard Trash Operations
EPM completed a Hazardous Waste/Contaminated Materials Screening Assessment in connection with the repurposing of the Bronx North Yard. The scope of work highlighted improvements to the yard including security, lighting, drainage, roadways, and parking areas. Other long term projects included potential demolition of current structures, construction of new employee facilities, and increased track material storage capacity.
The screening assessment was conducted to identify potential sources of hazardous or contaminated materials that could impact project construction. This assessment consisted of a review of historic aerial photographs; review of historic Sanborn Maps and review of federal, state, and local agency environmental records. Potential sites of environmental concern were identified based on the known or suspected presence of hazardous materials, and the potential for such materials to impact the limits of construction for the project.
Based on EPM’s assessment, a Phase II sampling investigation would be required to confirm actual site conditions.
Empire State Trail - Maybrook Trailway
EPM performed a Hazardous Material Screening Assessment to identify potential sources of hazardous or contaminated materials which could impact project construction and operation of the Maybrook Trailway (formerly known as the Beacon Line Rail Trail). The Maybrook Trailway will be a shared-use bicycling and pedestrian path running along a 25-mile portion of the Beacon Line Corridor from Brewster, NY to Hopewell Junction, NY.
Based on the project corridor’s historic use as a rail operation, EPM recommended that representative soil samples also be collected from the corridor to establish overall conditions. EPM prepared a Phase II Field Sampling Plan to outline procedures for collecting soil samples for environmental laboratory analysis. Results identified disposal requirements for excess material, evaluated onsite beneficial reuse options, and determined whether special health and safety precautions were warranted during construction.
Repair/Reconstruction of Five Undergrade Bridges East of Hudson River
EPM performed a Hazardous Material Survey in support of the repair or replacement of five undergrade bridges located on the Harlem, Hudson and New Haven lines east of the Hudson River. Three of the bridges also warranted investigation of possible contaminated soils since the reconstruction design called for excavation of foundations.
EPM prepared work plans for approval by Metro-North.
Field inspection staff collected bulk samples of suspected asbestos containing materials and lead paint by an ELAP certified laboratory. EPM obtained soil samples from geotechnical borings and submitted them for lab analysis.
Hazardous material investigation reports were prepared.
Grand Central Terminal
As a sub-consultant, EPM performed an investigation of both suspected asbestos and lead containing materials in areas to be impacted by repair efforts to address water leakage at Grand Central Terminal. The project scope included the 45th Street Bridge, Park Avenue Viaduct, GCT Façade and Balustrade, 42nd Street sidewalk and Vanderbilt Avenue.
Prior to field inspections, EPM reviewed several existing records including previous asbestos and lead survey reports.
EPM submitted a detailed survey report which included recommendations for asbestos and lead remediation.
Remediation design documents were prepared and several Site Specific Variances of Industrial Code Rule 56 Regulations were obtained for multiple site conditions. The abatement design included the development of abatement specifications, drawings and detailed cost estimates.
Fordham Station
EPM performed hazardous materials surveys for asbestos, lead based paint, universal wastes, and contaminated soils, in all accessible areas to be impacted by a planned widening of the northbound platform for the Fordham Station Capacity Improvement Project.
Existing asbestos and lead survey reports prepared by another consultant team were reviewed prior to collecting additional samples of suspected asbestos and lead materials. EPM also noted the location of fluorescent and high intensity discharge bulbs with presumed PCB-contaminated ballasts. Subsurface soil samples from an area adjacent to the existing platform were collected and tested for the presence of various organic and elemental contaminants. A detailed hazardous materials report was prepared and submitted.
Remediation design documents were prepared for the abatement of asbestos, lead and Universal Waste. The abatement design included the development of abatement specifications and drawings.
Harlem River Lift Bridge
EPM performed a Hazardous Materials Investigation for the Harlem River Lift Bridge Safety and Security Study. Prior to all field visits, EPM submitted Safe Work Plan.
The investigation included reviewing all existing data to determine the existence of hazardous materials to be impacted by this project. EPM has participated in two projects involving the Harlem River Lift Bridge: the Circuit Breaker House Replacement Project and the Cable Replacement project. For each project EPM conducted miscellaneous hazardous material investigations and prepared hazardous materials abatement design documentation as needed.
EPM conducted field surveys for asbestos and lead containing materials, contaminated soil, river mud, and universal wastes. Then EPM prepared a Hazardous Material Assessment and provided hazardous material abatement specifications and notes utilizing MNR baseline specifications, as well as, applying for any site-specific variances required per specific executions of work.
