Ensuring compliance with the Indiana Department of Environmental Management (IDEM) wastewater regulations is crucial for avoiding fines and maintaining environmental responsibility. Preparing for an IDEM wastewater compliance audit requires thorough documentation, proper record-keeping, and adherence to best practices.

1. Review Regulatory Requirements

Ensure that your facility is aware of all applicable IDEM wastewater regulations, permit conditions, and compliance obligations.

Steps to Take:

  • Review your wastewater discharge permit for specific requirements.
  • Stay updated on any recent regulatory changes.
  • Consult with an environmental compliance expert if needed.

2. Maintain Accurate and Complete Records

IDEM auditors will review documentation related to wastewater treatment, discharge monitoring, and compliance measures.

Essential Records to Have:

  • Laboratory test results for wastewater discharge.
  • Maintenance logs for treatment equipment.
  • Corrective action records for past violations.

3. Conduct Internal Audits

Performing an internal compliance audit can help identify potential issues before IDEM conducts its inspection.

  • Ensure proper calibration of monitoring equipment.
  • Check for any unauthorized discharges or exceedances.

4. Train Employees on Compliance Procedures

Employees involved in wastewater management should be well-trained in compliance requirements and best practices.

Training Focus Areas:

  • Proper wastewater handling and treatment procedures.
  • Emergency response and spill management.
  • Understanding and adhering to IDEM regulations.

5. Be Prepared for On-Site Inspection

When IDEM auditors arrive, your facility should be ready for a smooth and transparent inspection process.

Inspection Preparation Tips:

  • Have all required documentation easily accessible.
  • Ensure treatment systems are operating correctly.
  • Assign a point of contact to guide the auditor through the facility.
