This September 1997 explosion released a phenol/formaldehyde resin mixture over the grounds of the site and onto a limited area of the adjacent Sherwin-Williams property. Several above-ground chemical storage tanks, process piping and water were also damaged by the explosion. During the subsequent emergency response (ER) activities to stabilize conditions at the site, many of the proposed RI Phase II activities were completed by GP. These ER activities included collecting 35 on-site soil samples and 13 soil samples at Sherwin-Williams, installing 11 shallow and two deep ground water monitoring wells, controlling the on-site perched ground water and removing the explosion damaged facility structures. The ER activities were completed in November 1998 with the reconstruction of the resin process area.
