(b) Authority exercised by the agency within its jurisdiction.
(c) Mission of the agency.
(d) Capability of the agency.
(e) Desire of the agency to implement the institutional control being considered.
(2) Contact the OE MCX for additional information on the application of institutional
controls to the EE/CA process.
c. Determination of Existing Institutional Controls. The existence of any current deed
restrictions or other type of institutional control that may have been placed on the property in the
past as a result of some other activity should be determined. If such restrictions are found to
already exist at a site, it may be easier to modify the existing restriction to address the OE risk
than to implement an entirely new institutional control.
9-6. Risk Characterization.
a. Purpose. A risk characterization is required as part of the EE/CA process. A risk
characterization of an OE site is conducted to determine the level of safety risk that exists at a
site as a result of the OE contamination. The risk characterization is a key component in
determining the level of removal action necessary to address the safety risk and the basis on
which subsequent cost-benefit analyses are conducted in the EE/CA.
b. Types of Risk Characterization Tools. There are two main types of risk
characterization tools: qualitative and quantitative. Either type of risk characterization tool may
be used, depending upon which most appropriately fulfills project requirements. For additional
information on the selection of risk characterization tools, contact the OE MCX.
9-7. Development and Evaluation of Response Action Alternatives.
a. Development of Response Action Alternatives. Once site-specific data has been
gathered and analyzed, potential site-specific response action alternatives will be developed. A
response action alternative may include physical OE removals, as well as any other alternatives
that reduce risk to the public. The alternatives will be developed based on existing site
conditions, historic use of the site, the existing or proposed land use, and the extent and depth of
OE. Site-specific alternatives must ensure the most effective use of resources, while providing
maximum return to the public.
b. Response Action Categories. Response action alternatives are classified into four
general categories: No DOD Action Indicated, Institutional Controls, Surface Clearance, and
