Permitted Industrial User

CCCSD's Source Control Section uses the Industrial User (IU) Permitting Program to oversee individual facilities or a group of businesses. This is to ensure that wastewater discharge quality remains within permitted limits. IU Permits require specific operation and maintenance logs to be kept, spill response plans to be developed, compliance certification reports to be filed, and discharge quality to be monitored. The District uses the IU classification process to determine the proper oversight for a particular business activity. Some types of businesses are subject to Federal pretreatment standards and must be classified as a Class II IU (e.g., plating operations, circuit-board manufacturing). Other types of business activities are eligible for permitting under the Special Discharge Permitting program (e.g., groundwater remediation projects).

In order to assist permitted businesses to understand and comply with the IU Permit requirements, the following information is available (Acrobat Reader required):
