Permanent Sealing of Orphan Well in Orange County Initial Study/Mitigated Negative Declaration

Permanent Sealing of Orphan Well in Orange County Initial Study/Mitigated Negative Declaration

The Permanent Sealing of Orphan Well in Orange County Project involves the State of California's plugging and abandoning (permanent sealing) of one (1) orphan well in an unincorporated area of Orange County, California. The well, identified as Well #1, is in the Brea-Olinda Oil Field north of Brea, California. Permanent sealing refers to the permanent closure and sealing of a well by placing cement and other approved materials in the former well. The Project schedule for Well #1 is estimated to last from three to five days. For well permanent sealing, the well would be cleaned out and then plugged with cement and inert mud to surface. Then, the well casing would be cut down to approximately five to 10 feet below ground level, and the site would be backfilled with soil up to ground level. After completion of the permanent sealing operations, the disturbed areas utilized for site access, permanent sealing work, and temporary equipment staging areas would undergo restoration to align with the landscape of the surrounding environment. Permanent sealing work would require some vegetation clearance to allow staging of equipment. Estimated surface disturbance is approximately half an acre.
