1. On or about August 15, 2023, a petroleum release was identified originating from a storage tank system owned by Cody Oil Company. The source of the release is located at 420 Highway 20, Cody. An approximate legal location is SW1/4, NW1/4, SE1/4, Section 07, Township 34N, Range 33W, Cherry County.

2. Follow-up investigation identified the effects of the release and led to the remedial actions proposed by NDEE. The investigation resulted in a determination that this ground water contamination event is defined as remedial action class one.

3. The source of the release has been removed. A Risk-Based Corrective Action (RBCA) Tier 2 assessment was conducted for one or more of the following exposure pathways of concern: surface soils, ground water ingestion, soil leaching to ground water, and intrusion of vapors to a structure from contaminated ground water and contaminated soils. The contaminant concentrations found were below the numerical levels used by the RBCA process to establish a need for further investigation or remediation. Based on the current site conditions and property use, the NDEE has determined that no further remedial action is necessary due to the lack of threat to human health or safety.

Information regarding this release is contained in the file: NDEE ID 5260, RA 081523-NM-1600.

Any person may receive further information or submit comments on the proposed action, and request or petition NDEE for a hearing, in writing, stating the nature of the issues to be raised in the hearing, on or before August 19, 2024.
