On July 9, 2012, EPA approved a RCRA Facility Investigation Work Plan, dated May 11, 2012, for the former Millennium Specialty Chemicals site. The first phase of the Work Plan to install 33 groundwater monitoring wells, and to collect one round of groundwater samples, surface (0-1 ft) and subsurface (4-5 ft) soil samples was completed. A summary of the preliminary soil and groundwater sampling results were submitted to EPA on April 16, 2013. The results indicate that the contaminants of concern are principally metals. Four metals: arsenic, barium, cadmium and lead, exhibit concentrations above MDE non-residential screening levels in surface and subsurface soil throughout the industrial portion of the site. Only two metals, arsenic and barium, exhibit dissolved phase concentrations (filtered groundwater samples) above MDE groundwater standards along boundary wells that discharge to Colgate Creek. Based on the preliminary soil and groundwater sampling results, the Responsible Party has developed a second phase investigation to sample offshore sediment and pore water to impact on Colgate Creek. The second phase work plan was approved on September 24, 2013 and the field work was completed in 2014. EPA is awaiting presentation of the results and proposal of the cleanup plan.
Millennium Specialty Chemicals historically manufactured paint pigments and amorphous silica gel at the Facility. Paint pigments including zinc lithopone, cadmium lithopone, cadmium pure, titanium dioxide and other inorganic pigments were produced from 1914 till 2005, and amorphous silica gel was produced from 1969 to 2006. In 2006, the facility declared bankruptcy and ceased operation, and by 2008, all structures were demolished, removed and leveled. The current owner is a bankruptcy trustee, Lyondell Environmental Custodial Trust, who is the Responsible Party to conduct a RCRA corrective action study pursuant to an August 19, 2010 Administrative Order using trust fund money allocated by the bankruptcy court.
