Reasons for Exemption
The proposed project would involve construction of a limited number of new monitoring wells and stream gauges. Monitoring wells would occupy approximately three square feet at the surface if vaulted individually or approximately 40 square feet at the surface if vaulted as a cluster. Stream gauges would consist of small segments of one-inch steel or PVC housing/standpipe. Therefore, these elements would be classified as small new equipment and facilities, and the Class 3 exemption is applicable. In addition, construction of the proposed project would consist only of minor public alterations in the condition of land and vegetation and would not involve the removal of healthy, mature, scenic trees. Therefore, the Class 4 exemption is applicable. Moreover, the proposed project would involve a monitoring well and stream gauge network to provide data to understand what actions in the region can enhance stream flows and to manage interconnected surface water depletion, evaluate stream flow conditions, and evaluate stream responses to enhancement efforts by all entities in the region. Furthermore, the proposed project would not result in a serious or major disturbance to an environmental resource. Therefore, the Class 6 exemption is applicable.
