The RAP for the Site will be limited to an area approx. 500 feet long 70 feet wide, with a maximum depth of 30 feet. The soil contamination, in part, due to past manufactured gas plant (MGP) and butadiene (the raw material for manufacturing of rubber) operations. contaminants include benzene, naphthalene, polycyclic aromatic hydrocarbons (PAHs), total petroleum hydrcarbons (TPHs), and dicyclopentadiene (DCPD). The project includes removal of contaminated soil in accordance with the methods and procedures presented in the RAP and in the Remedial Design document to be prepared prior to implementing remedial activities.
