Expedited Bronze Foundry Cleanup Performed Under Cost Recovery
Cox-Colvin & Associates was approached by the owner of a large industrial park concerning potential environmental issues associated with a non-ferrous metal foundry operation leasing one of their buildings. Cox-Colvin completed a Phase I and Phase II site assessment of the facility and determined that fugitive dust emissions containing elevated concentrations of copper, lead, nickel, tin, and zinc had contaminated the interior of the building, roof, storm sewers, and grounds. Based on the assessments and our projected cost to investigate and restore the property to Ohio Voluntary Action Program (VAP) commercial/industrial standards, the owner elected to evict the tenant and secure a lump sum payment to cover the expected costs to restore the facility. Cox-Colvin provided oversight for the environmental restoration of the interior and exterior of the facility, the grounds, and storm sewers. Restoration efforts were completed within five months with the cost to conduct the cleanup fully covered by the lump sum payment obtained from the foundry owner.
We implemented the entire project so that it could proceed through the Ohio VAP, should the property owner elect to do so. Metal concentration ratios from interior dust samples were used to demonstrate to the foundry owner that the soil and storm sewer sediment had been affected by their operations, and not by the actions of previous tenants. Cox-Colvin completed a human health risk assessment and used multiple chemical adjustments to establish cleanup goals.
A combination of pressure washing and industrial vacuums was used to completely clean the interior of the 30,000 square foot facility containing the foundry, machine shop, storage areas, office space, break room, and employee locker room. All fugitive dust, sediment, and carpet was collected and shipped for proper disposal. Nearly a one half mile of storm sewer drain line were plugged and pressure washed and all rinse waters were collected and treated using on-site equipment.
