Critical evaluation of existing empirical evidence to test whether there was a gradation in nest success as a function of distance from an edge. Researchers investigating this question have been inconsistent in their experimental designs, making generalizations about edge-effect patterns difficult.

The purpose of this document is to provide personnel in all areas of the Resolution Copper Mining LLC (RCM) operation access to procedures for the proper handling and disposal of hazardous materials and hazardous waste so as to protect the environment and to comply with laws and regulations.
