Notice of Exemption
Exempt Status
Categorical Exemption
Type, Section or Code
Class 1; Existing Facilities (15301), Class 4; Minor Alterations to Land (15304), Class 11; Accessory Structures (15311)
Reasons for Exemption
The Project is categorically exempt under Class 1 because it involves a minor modification to an existing facility for the purpose of facilitating the operation of a health protection device. The Project is categorically exempt under Class 4 because it involves negligible changes to the existing landfill's leachate treatment operations and will not involve the removal of health, mature, scenic trees. The Project is categorically exempt under Class 11 because it is an accessory structure that will be constructed appurtenant to the site’s existing industrial landfill use. The Project qualifies for the “common sense” exemption because it can be determined with certainty that it will not have significant environmental effects.
