Case summary

SEPTEMBER 3, 2024 - ADMINISTRATIVE ORDER ON CONSENT to assess the overall operation of the Facility. The CEI identified violations of the Permit, including a failure to properly operate and maintain facilities and systems for collection and treatment, violations of the Permit?s effluent limits, and violations of the Permit?s requirements to conduct effluent monitoring and submit DMRs reporting the results of effluent monitoring. The EPA?s findings and recommendations were summarized in the CEI Report dated June 28, 2023 The CEI showed that MBCI was in violation of the Operation and Maintenance Section of the Permit, Part III.B.1. Specific Operations and Maintenance violations are listed starting on page 9 of the report, Attachment B. On February 9, 2024, the EPA sent a Notice of Violations (NOV) letter to MBCI regarding violations identified during the CEI as well as its review of ICIS. The NOV noted failure to submit DMRs on the schedule dates, , effluent limitation violations of the Permit, failure to sample, lapse in the whole effluent toxicity testing, and failure to properly operate and maintain the facility. On March 28, 2024, the EPA and representatives of MBCI Department of Utilities held a conference call to discuss the Permit violations. MBCI confirmed the Permit violations and drafted a report dated April 12, 2024, explaining the violations and detailing corrective actions to address them. MBCI has violated the Effluent Limitations and Monitoring Requirements Section (Part I.A) and Proper Operations and Maintenance of Pollution Controls Section (Part III.B.1) of the Permit, issued pursuant to Section 402 of the CWA, 33 U.S.C. ? 1342, by discharging pollutants into Box Creek, a navigable water and water of the United States, in excess of the limitations allowed in the Permit, and by failing to properly operate and maintain the Facility. Based on the above, the EPA finds that MBCI is in violation of Section 301(a) of the CWA, 33 U.S.C. ? 1311(a), and the above referenced provisions of the Permit. Within 90 days of the effective date of this AOC, MBCI shall develop and submit to the EPA for review and approval a Corrective Action Plan (Plan). The goal of the Plan is to determine the cause of the violations alleged above, correct the violations, and bring MBCI into full compliance with the Permit. The Plan shall include a description of the necessary corrective action(s) that provide for the elimination of effluent violations of the Permit. The Plan shall also include a schedule for full implementation that does not exceed one hundred and 180 days following the EPA?s approval. Upon review of the proposed Plan, the EPA may: 1) approve the Plan in writing; or 2) in the event the Plan is not approved, provide written comments to MBCI identifying any deficiencies. Within 30 days of the date of receipt of comments identifying deficiencies, MBCI shall modify the Plan to address any deficiencies and submit the modified Plan to the EPA for final review and approval. Should the EPA determine that MBCI has failed to resolve any deficiencies, the EPA reserves the right to require additional revisions and resubmissions until the deficiencies are satisfactorily addressed. Resubmission of the Plan without adequately addressing the EPA?s comments may be deemed a violation of this AOC. MBCI shall begin implementation of the Plan immediately upon receipt of the EPA?s written approval of the Plan.
