PUBLIC NOTICE
NEBRASKA DEPARTMENT OF WATER, ENERGY, AND ENVIRONMENT
LINCOLN, NEBRASKA
Pursuant to DWEE’s Title 118 - Ground Water Quality Standards and Use Classification, public notification and opportunity for comment is hereby given of the following:
1. On May 29, 2025, a petroleum release was identified originating from a storage tank system located at 518 Railroad Avenue, Newman Grove. An approximate legal location is NW1/4, SE1/4, NW1/4, Section 33, Township 21N, Range 04W, Madison County.
2. Follow-up investigation identified the effects of the release and led to the remedial actions proposed by DWEE. The investigation resulted in a determination that this ground water contamination event is defined as remedial action class 1.
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 subsurface exposure pathways of concern: ground water ingestion, soil leaching to ground water, intrusion of vapors from contaminated ground water, and intrusion of vapors from contaminated subsurface soils. Some of the contaminant concentrations found are above the Site–Specific Target Levels (SSTLs) determined under the RBCA process and therefore require remediation to the SSTLs. The specific numerical values will be provided by DWEE upon request. When the site has been remediated to the SSTLs established for the chemicals of concern, and a period of post-remedial monitoring confirms that the cleanup was successful for the current site conditions and property use, the site file will be closed.
Information regarding this release is contained in the file: Facility ID 121171,
Any person may receive further information or submit comments on the proposed action, and request or petition DWEE for a hearing, in writing, stating the nature of the issues to be raised in the hearing, on or before April 7, 2026. A final decision by the Director will be made in a manner provided by Title 115, NAC Ch. 3. Direct written correspondence to Director, DWEE, 245 Fallbrook Blvd, Ste 100, Lincoln, Nebraska 68521‑6732.
