PROJECT ARCHIVES: Arc Environmental, Inc. was retained by the University of Maryland Baltimore County (UMBC) to perform an inspection of the Hillcrest Building located at UMBC in Catonsville, Maryland. The inspection was conducted to identify asbestos containing materials (ACM), lead-based paint, and to quantify hazardous materials prior to the planned demolition of the structure. Arc Environmental compiled a list of all ACM throughout the Site and provided illustrated locations of all ACM in AutoCAD drawings. The following ACM was identified: floor tile and mastic; roof flashing mastic; thermal system insulation pipe insulation; gypsum board and joint compound, and ceiling tile.
The hazardous materials survey identified other hazardous building materials as well as aboveground storage tanks. Design specifications and drawings for the abatement of hazardous materials were then developed. A cost estimate for remediation of the asbestos and other hazardous building was provided to the Owner. Arc Environmental then provided oversight and monitoring of the abatement contractor, which involved documenting proper removal methods and quantities; cleaning techniques and requirements; disposal methods and confirmation; and visual and phase contrast microscopy clearance of each phase of the abatement. The project was completed one month ahead of schedule. |

Sampling for lead-based paint was conducted using x-ray fluroescence spectrometry (XRF) to determine which building components contained lead-based paint to protect demolition workers. A Toxicity Characteristic Leaching Procedure (TCLP) sample for lead-based paint of representative building components was taken and indicated that the waste stream was not characterized as hazardous waste.
