Title

Northshore at Mandalay Bay

Description

DTSC approved the Reponse Plan submitted pursuant to LCRRA which 1) outlines the implementation of completed and future response actions expressly authorized by the Feasibility Study/Remedial Action Plan (FS/RAP), as modified by the Partial Remedial Action Completion Report (PRACR); and 2) incorporated the vapor intrusion mitigation systems into the Residential Project. The selected remedy for the Residential Project will include Vapor Intrusion Mitigation. The process to install VIM includes the development of a design and the installation of the VIM Systems that incorporates both passive and active VIM technologies. The VIM Systems slightly modify the building foundations to create a vented layer beneath the foundation slab which is depressurized with a small fan that preents vapors from the sub-slab from entering the residences within the Residential Project. Ina ddition to the small depressurizing fan, either a highly permeable or low permeable barrier is used to diminish the potential for resident exposure. NOTE: See NOD for full project description
