This proposal involves removing existing equipment, cleaning out the wells, and plugging with cement to abandon the three wells.

The proposal does not involve any changes to the well's structures (the wellbores).

Categorical Exemption
Type, Section or Code
Class 4, Minor Alterations to Land (14 CCR §§ 15304, 1684.2)
Reasons for Exemption
Class 4 applies because the rework “consists of drilling operations that result in only minor alterations with negligible or no permanent effects to the existing condition of the land, water, air, and/or vegetation.” The abandon is intended to maintain the current level of service and will not involve expanding the facility or operations. The proposed activities and temporary equipment will be contained within the existing well pads. As a result, there will be no new ground disturbances. There are no expected impacts on biological resources as the proposed Project will not disturb undisturbed areas.
