How much do you know
about…LEHR?
• The LEHR site has soil contamination – some caused by the U.S.
Department of Energy’s research, some by UCD’s landfills.
• The cleanup of the contamination is regulated by the U.S. EPA as a
Superfund site. The State of California also regulates the cleanup.
• Although most of the contaminants in the DOE areas were removed,
some traces remain in the subsurface. Land use restrictions are in
place to prevent development where traces of contaminants remain.
• In the UCD areas, the remedy for contaminated soils is not yet in
place. Traces of soil contamination are present in the subsurface.
• UCD is required by Federal order to manage these areas to
minimize worker exposure to residual contamination during soildisturbing work.

Soil Disturbance Permit
and Training
• Requirements put in place in 2012 restricting land use
• Soil Management Plan describes procedures for disturbing soils
• Tight controls necessary to protect human health and environment
• EH&S is responsible for implementing these requirements
• Currently restricting land use in the same manner as on the DOE
site
• EH&S responsible for controlling activities in restricted areas
• In the future, additional land use restrictions may be imposed
• Required for soil disturbing activities in EITHER area
• Campus personnel required to follow all applicable laws,
regulations, and requirements

drilling, or management of soil generated by such work.
Example: repair of a water main leak
DOES NOT APPLY TO landscaping, fire protection, or
maintenance work that is
• Less than 1 foot below surface AND
• Less than 5 cu yd of soil displaced AND
• All soil is returned to disturbed area.
Example: removing invasive weeds by hand
