3. Investigation of Noncompliance

The Industrial Waste Control Section will generally investigate user compliance with permits or the provisions of the SUR in three ways:

1. On-site inspections of the user to include scheduled and unscheduled visits;

2. Scheduled and/or unscheduled sampling of the users effluent wastewater discharge;

3. Review of self-monitoring data.

The compliance status of Significant Industrial Users will be evaluated at a minimum once every 6 months.
