VERTEX performed due diligence activities addressing all buildings, facilities and operations at a coal-fired power plant in Illinois. VERTEX completed a review of the existing Phase I and performed a comprehensive Phase II to investigate all areas of concern (AOC) at the site. The due diligence included the advancement of 14 soil borings and soil and groundwater sampling activities. Each boring was converted into a groundwater monitoring well to facilitate the collection of groundwater samples. Additionally, three grab samples of standing water located in the building basement were collected and characterized. The AOC’s included Former Fuel Oil USTs, a Former Truck Rental Garage, a Former Coal/Coal Ash Unloading Area, and Transformer Substation that reportedly leaked oil to surface soils.
VERTEX performed a comprehensive survey of the power plant structures for compliance with the National Emissions Standards for Hazardous Air Pollutants (NESHAP). Our team identified Asbestos Containing Materials (ACM) and materials that would require abatement prior to proposed demolition activities. VERTEX designed the asbestos survey following our in-house sampling protocol, which is based in part on the EPA Asbestos Hazard Emergency Response Act (AHERA) regulations. VERTEX utilized our on-staff qualified and licensed asbestos inspector(s) to collect approximately 350 bulk material samples and analyzed the samples utilizing Polarized Light Microscopy with Dispersion Staining (PLM/DS) for friable materials, PLM for Non-Friable Organically Bound (NOB) matrices and Transmission Electron Microscopy (TEM) for NOB. The results of the comprehensive survey were used to obtain permits for the removal of the ACM.
VERTEX developed an engineering cost estimate for complete decommissioning and demolition of the power plant, accounting for the asbestos abatement, management of hazardous materials, decommissioning of the power plant, salvage of selected equipment, demolition of the buildings and structures and the recycling of scrap, site restoration and the establishment of a permanent storm water management system at the site. VERTEX prepared a financial and schedule risk register to identify uncertain aspects of the demolition work that could have a significant impact on overall approach, scope, cost or schedule. After initial development, the cost estimate and the risk register were subjected to quality control and assurance checks. VERTEX used the risk register to determine an appropriate level of contingency allowance that should be included in the estimate. The information utilized in developing the estimate (e.g., estimated takeoff quantities) was documented in a manner suitable for use during the execution phase of the project and to facilitate review.
