Does Phillips 66 #258 have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in March 2026. The violations listed here began between September 2025 and March 2026. By type: 9 public notice, recordkeeping or other and 3 monitoring and reporting. The contaminant or rule involved most often is Public Notice (9 of them). EPA lists 9 as unaddressed, 2 as resolved and 1 as archived. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement. 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.
