Automotive Manufacturing Plant


Sandusky, Ohio


Ohio Voluntary Action Program (VAP) Phase I and Phase II Property Assessments (PA) of a site covering over 300 acres which had been utilized for manufacturing automotive parts since the 1950’s. It is currently an active automotive parts plant, and includes a large agricultural tract, a water filled quarry, multiple former sludge ponds and a landfill.


The Phase I PA noted over 30 Identified Areas (IAs), some of which are listed below:

  • Press pits, sumps, and trenches associated with former manufacturing and painting operations

  • Former plating line

  • Former paint booths and lines

  • Former phosphate coating line

  • Underground piping for chemicals and industrial waste sewers

  • A solid waste disposal area

  • Paint disposal areas

  • Former/current ASTs and USTs

  • Rail spurs

  • Sludge Ponds


The Phase II PA included:

  • Geophysical surveys

  • Over 100 soil borings

  • Hand auger borings

  • Sediment sample collection

  • Over 20 groundwater monitoring wells and rehabilitation of numerous existing wells

  • Soil, sediment and groundwater sampling and analysis



The results of the subsurface investigations concluded the following:


  • The geology of the site consisted primarily of clay, with some areas of overlying fill materials, underlain by shallow bedrock. Separate phase petroleum product (oil) was observed beneath the main building. The basement of the main building contained a dewatering sump system, which essentially acted to provide a capture zone for the oil. The water filled quarry was formerly used as disposal area and the on-site process ditches conveyed non-contact cooling water for the manufacturing process.   


  • Contaminants of concern encountered included multiple VOCs, SVOCs, metals, cyanide, petroleum hydrocarbons and PCBs.


The results of the Risk Assessment determined that the Property was not in compliance with applicable soil and groundwater standards.  Conceptual remedial actions (monitored natural attenuation, soil excavation and off-site disposal, sediment removal etc.) were developed.
