How does Spring Creek Mine compare with other water systems in Big Horn County?
By EPA's size categories, Spring Creek Mine is a very small system (500 people or fewer). Big Horn County has 23 active public water systems. Its population served is about 55% below the county average of 449 people per system, and accounts for 1.9% of the 10,335 people reported by systems filed under the county. Across Montana, the 2,378 active systems average 489 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Spring Creek Mine is about half of that figure.
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. Montana has 319 active non-transient non-community water systems, 13% of the state's 2,378 active systems. Purchased surface water means the system buys surface water from another public water system rather than drawing its own. 212 Montana systems (8.9%) list purchased surface water as their primary source.
Who owns and regulates Spring Creek Mine?
EPA lists Spring Creek Mine as privately owned. The MT state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 11 of the 23 active systems in Big Horn County (48%) are also privately owned.
Does Spring Creek Mine have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in June 2022. The violations listed here began between July 1995 and June 2022. By type: 10 monitoring and reporting and 2 monitoring. The contaminant or rule involved most often is Total coliform bacteria (TCR) (8 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.
