AMBLER BOILER HOUSE REDEVELOPMENT AMBLER BH DEVELOPMENT PARTNERS

AMBLER BOILER HOUSE REDEVELOPMENT • AMBLER BH DEVELOPMENT PARTNERS, LLC • RT ENVIRONMENTAL SERVICES, INC.

Project Description

Environmental Conditions

Additional Environmental Conditions • 20, 000 Gallon Underground Storage Tank (#6 Fuel Oil) • Historic Fill Located Throughout the Property (lead and arsenic impacted)

PLANNED REMEDIAL ACTIVITIES • Asbestos Abatement – removal of debris throughout the boiler house and surrounding surface areas, flat roof, transite panels, and remaining insulation. All building surfaces to be power washed to remove any residual asbestos fibers; all water to be collected and properly filtered and disposed. • UST Removal – pumping out remaining oil, cleaning the shell of the UST and removal of the UST. Post UST removal soil samples to confirm clean closure. • Drum/Container Removal – remaining drums and containers will be characterized and prepared for proper disposal offsite.

PLANNED REMEDIAL ACTIVITIES • Hazardous Miscellaneous Materials Removal – miscellaneous materials includes mercury containing light bulbs and switches, PCB ballasts, propane tanks, batteries, refrigeration units, cleaners, will be properly disposed offsite. • Historic Fill Management – historic fill present on the property will be placed as fill material in the basement of the boiler house. All historic fill material at the site will be capped with concrete, asphalt or soil.

ACTIONS BEING IMPLEMENTED DURING REMDIAL ACTIVITIES TO ASSURE PUBLIC SAFETY • Restricted Access to the Site (temporary fencing). • Establishment of critical barriers at doors and windows during Asbestos abatement. • Air monitoring at the perimeter of the boiler house during Asbestos abatement. Transmission Electron Microscopy (TEM) for laboratory analysis (action level of 0. 01 fibers/cc). • NO VISIBLE EMISSIONS. • Potential corrective measures: dust control, use of more water to control emissions, altering abatement method. • RT field inspection during all abatement work. • Dust control during historic fill movement (NO VISIBLE EMSSIONS). • Asbestos sampling for historic fill prior to placement in the boiler house

ANTICIPATED REDEVELOPMENT SCHEDULE • Remedial Activities and Selective Demolition to be Bid in November 2010 • Remedial Implementation December 2010 with Completion expected by March 2011 • Building Construction Commencement in April 2011
