'The Master Metals site was a former secondary lead smelter (Master Metals, Inc.) and nearby residential properties (Holmden Avenue) where lead bearing materials were deposited as fill. This action is necessary to abate an imminent and substantial threat to public health and the environment posed by the presence of lead contaminated surface soils outside the fence line of the Master Metals facility. This non-time critical removal action is recommended to expeditiously reduce the actual or potential exposure of nearby human populations to hazardous substances from the site.'
