Join us on October 23 for the 2024 Industrial User Academy! Please find your pre-study materials at the bottom of this webpage and complete these readings before arriving for the main event. 

Central San’s Environmental Compliance 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 the keeping of specific operation and maintenance, development of spill response plans, filing of compliance certification reports, and monitoring of discharge quality. Central San 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 Significant Industrial User (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:
