Workshop 3, California's Environmental Challenges: What Do We Do with Large Operating Facilities
« All Publications

California has hundreds of large facilities that have been in operation for many decades (refineries, bulk terminals, tank farms, foundries, factories etc.) which are vital for the state's continuing economy.

Most of these are operating properties that contain significant amounts of persistent contaminants and have soil/groundwater impacts on-site and off-site above clean up levels. These facilities are typically in urban areas and are integral to the economic engines of the community and State. Despite years of characterization and remediation, contaminants remain above levels needed for closure. The technical and economic means to restore these sites may not exist. However, for many of these sites, there may be little or no imminent risk to humans or the environment. How to clean and continue to manage these sites in a manner that does not pose a threat to current and future public health, environment and water resources presents a real challenge into the future. This workshop will explore the risks these sites pose, the technical and economic feasibility of cleaning or reducing mass at these sites, the time frame to reach acceptable levels, the greenhouse gas emissions to reach such levels, existing regulatory frameworks, and finally balancing all the above interconnected factors and getting community acceptance. Panel members will focus on their experiences in answering the challenges and some approaches to continue managing these operating sites in California.
