What does “non-transient non-community water system” mean?
A non-transient non-community water system regularly serves at least 25 of the same people for more than six months a year, but not where they live. Schools, factories, office buildings and hospitals with their own supply are typical examples. Wyoming has 91 active non-transient non-community water systems, 12% of the state's 775 active systems. Surface water means the system draws its water from rivers, lakes, streams or reservoirs. 50 Wyoming systems (6.5%) list surface water as their primary source.
Who owns and regulates Hilcorp Carter Creek Gas Plant?
EPA lists Hilcorp Carter Creek Gas Plant as privately owned. The WY state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 5 of the 12 active systems in Uinta County (42%) are also privately owned.
Does Hilcorp Carter Creek Gas Plant have drinking water violations?
Of the 12 most recent violations in EPA's records, 7 are health-based, and the most recent began in January 2026. The violations listed here began between January 2004 and January 2026. By type: 6 required treatment not met, 5 monitoring and reporting and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Surface Water Treatment Rule (4 of them). EPA lists 11 as resolved and 1 as archived. Resolved means at least one resolving action is on record: the system returned to compliance, the rule no longer applies, or no further action was needed. Archived means the violation was not marked resolved but is more than five years past the end of the noncompliance period, so it no longer counts toward current compliance status.
