What: Public hearing regarding the Bishop Well Incident
When: Thursday, June 26, 2025, at 10:30 a.m.
Where: virtual over zoom
On 6/10/25 ECMC received and posted Chevron’s Accident Report (form 22) and attached Root Cause Analysis. ECMC uses the Root Cause Analysis to further its investigation of the incident that will inform what enforcement action may be warranted and to determine what measures may need to be taken, if any, to minimize the likelihood of the incident occurring again.
Key documentation pertaining to the ways in which ECMC is overseeing the Bishop incident includes:
- ECMC posted Chevron’s Environmental Sampling and Analysis Plan on 4/17/25. This document describes the ways in which Chevron must take samples to investigate impacts from the spill. Subsequently, ECMC posted Chevron’s Analytical of Source Material documentation on 4/24/25. This document analyzes the data provided by initial samples.
- ECMC posted Chevron’s Site Investigation and Remediation Workplan (Form 27) on 5/1/25. The Workplan describes the ways in which impacts from the incident will be investigated, delineated, and remediated and how the remediation will be monitored and validated.
- The numerous impacts are being segregated into ~300 specific remediation sites (referred to as T-parcels) spanning just over a 1.5-mile radius from the Bishop well due to the variety of environmental impacts. In turn, the site-specific remediation and completion timelines for each T-parcel is unique.
- ECMC issued a Notice to Operators on 5/2/25 to minimize the likelihood of the incident occurring again.
The Spill/Release scout card on ECMC’s public database, COGIS, is a repository for all documentation. ECMC assigned Spill/Release ID #489797 to the Bishop incident. ECMC also posts the corresponding data that supports the implementation of these plans. As of 6/18/25, ECMC has received and posted more than 1,000 analytical reports from field sampling activities conducted by Chevron and overseen by ECMC as part of the ongoing investigation. Plain language summaries of the data are available online.
