The Industrial Waste Control section will generally investigate user compliance with permits or the provisions of the Sewer Use Resolution (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 all monitoring data.
The compliance status of Significant Industrial Users (SIU) will be evaluated at a minimum once every six months.
