This work Contact: <br /> plan includes a brief introduction,background,and the scope of work that will be Mark Becker � <br /> conducted for this Pbase H ESA. <br /> Introduction <br /> Extension: <br /> The objective of this Phase II ESA is to assess,from collected data, "baseline" soil 831-338-1418 <br /> conditions at the site. Suspect contaminants include total petroleum hydrocarbons <br /> (TPH;e.g.,fuel oil),metals and volatile organic compounds (VOCs). ARCADIS <br /> Geraghty&Miller will install Soil borings and collect soil samples to meet the above <br /> stated objective. <br /> Background <br /> i <br /> The site comprises approximately one-half acre located in the southeast corner of the <br /> Newark Sierra Paperboard facility (Newark Sierra). Currently, the site is vacant and <br /> unpaved. According to information provided during conversations with Newark <br /> Sierra personnel, a Number 6 fuel oil underground storage tank(UST)was formerly <br /> located on the site, The UST was reportedly removed,and impacted soil excavated <br /> and appropriately disposed. Additionally,according to Newark Sierra personnel, <br /> results from sampling of four groundwater monitoring wells at the site indicate that <br /> groundwater has not been adversely impacted by the former UST. <br /> The four soil borings to be installed as part of this Phase H ESA are intended to <br /> assess "baseline" soil conditions in areas of the site not previously investigated as <br /> part of the UST removal and soil rernediation. <br /> i <br /> I <br />
