WDID 5R45I020677Twin Mine Active Facility profile
Records as the State Water Board publishes them in SMARTS, with the source's own types, statuses and identifiers. A listed inspection, violation or enforcement action is not, on its own, a finding about the facility's current compliance, and the absence of records does not establish compliance.
