NOE - Notice of Exemption

Document Description
These further restrictions will prohibit the construction of residences without an evaluation of potential soil vapor intrusion of volatile organic compounds into future buildings and the implementation of engineering controls if deemed necessary. The evaluation and implementation of engineering controls will be subject to DTSC approval. The project also modifies the cleanup goal for vinyl chloride (VC) in groundwater from 3.8 micrograms per liter to 47 micrograms per liter. The proposed cleanup goal is protective of human health and the environment under the current industrial or commercial land use scenario. This change will allow discontinuation of groundwater monitoring as groundwater concentrations will have attained the revised cleanup goal for four sampling events over a period of approximately two years.
