The Site Mitigation Unit's (SMU) goal is protection of public health and the environment while facilitating completion of site clean-up projects in an expeditious manner. The Los Angeles County Certified Unified Program Agency (LACoCUPA) established its Site Mitigation Unit in 1986. Since 1986 SMU has issued closure for over 800 sites. SMU's voluntary oversight program operates per Health and Safety Code §101480 which allows oversight of certain contaminated sites. In addition, in May 2008, Department of Toxic Substances Control (DTSC) delegated corrective action oversight authority to LACoCUPA under chapter 6.5 of Division 20 of California Health and Safety code to implement corrective action under consent agreement at CUPA facilities within its jurisdiction. SMU voluntary oversight and corrective action oversight programs are options in addition to DTSC and Regional Water Quality Control Board (RWQCB) oversight programs for residents and businesses of Los Angeles County seeking oversight in a cost effective and timely manner for cleanup of their contaminated properties.

Oversight services are provided on a fee for service basis. Service is provided in all cities of Los Angeles County except El Segundo, Glendale, Long Beach, Santa Fe Springs and Vernon.
