Pursuant to NDEE Title 118 - Ground Water Quality Standards and Use Classification, public notification and opportunity for comment is hereby given of the following:
1. On or about June 15, 2023, a petroleum release was identified originating from a locomotive owned by the Union Pacific Railroad. The source of the release is located at the railroad crossing at the intersection of Road 427 and Hwy 30. An approximate legal location is NE1/4, SW1/4, Section 29, Township 10N, Range 22W, Dawson 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 two.
3. The source of the release has been removed. A Risk-Based Corrective Action (RBCA) Tier 1 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 998923, RA 061523-RS-2030.
