Charter <br /> Hi Mike, <br /> they need to address how future worker safety ( development) will be assured if the <br /> soil gross contamination is shallow enough to allow exposure (e.g.., City building <br /> permit would require removal of soil).

Instead, they used diesel soil data and conducted <br /> an ESL evaluation. Nuel commented that 5,300 mg/kg of TPHd is roughly one order of <br /> magnatude OVER gross contam levels for "middle distillates" . The site is capped with. <br /> black top and concrete and is now, and will be/stay, an active fuel/gas station in the <br />
