Type B Technical Information Document: Approaches to the Assessment of Injury to Soil Arising from Discharges of Hazardous Substances and Oil

摘要

The document provides information involving the determination of injury to soil, a portion of the geologic resource described in the 43 CFR Part 11 regulations. The document was developed in conjunction with the 'type B' natural resource damage assessment regulations. It supplies descriptive information on methods for use in determining the nature and magnitude of soil injury based on the chemical, physical, and biological characteristics of the soil. The document explains how injuries to the soil resource can be translated into a reduction in services provided by that soil in comparison to local baseline conditions of uninjured soils. It also provides information for determining the ability and time necessary for the soil to recover from the injury. The information in the document supplements the guidance provided in 43 CFR Part 11, but is not required to be followed to obtain the rebuttable presumption provided by those regulations.
