Notice of Exemption
Exempt Status
Categorical Exemption
Type, Section or Code
Section 15307
Reasons for Exemption
The proposed project is categorically exempt from environmental review in accordance with Section 15307 of the California Environmental Quality Act (CEQA) Guidelines and Placer County Code Section 18.36.070 (Class 7 – Actions by regulatory agencies for protection of natural resources) and statutorily exempt in accordance with Section 15269(c) of CEQA and Placer County Code Section 18.36.010 (Statutory Exemptions – Emergency Projects) because the sheet pile wall is an emergency measure necessary to ensure a pit capture event does not occur. If the riverbank erodes to the point of failure, impounded water in a 70-acre mine wash water settling pond would be released into the river system in an uncontrolled flood event resulting in potentially catastrophic downstream flooding and property damage.
