Morro Bay Municipal Code Art. IV Industrial Wastewater Discharge Permits

Industrial wastewater discharge permits shall be issued under the following categories as determined by the utilities division/department manager after review of the permit application as described in section 13.12.440 of this chapter. The utilities division/department manager may determine, upon review of the permit application, that no permit is required for certain small industries and commercial users.

A. General industrial/commercial user permits (Class "G" dischargers). General industrial/commercial user permits may be issued to certain small industries and some commercial users whose industrial discharges do not significantly impact the POTW, degrade wastewater quality or contaminate sludge. Industries that have the potential to discharge a non-domestic or process waste stream, but at the present time discharge only sanitary waste, may also be included in this group.

B. Significant industrial user (SIU) permits (Class "S" dischargers). SIU permits shall be issued to those industries which are determined by the utilities division/department manager to be significant industrial users (SIUs) as defined in subsection 13.12.130(UU) of this chapter. The utilities division/department manager may require other users to obtain an SIU permit as necessary to carry out the purposes of this chapter.

C. Food facility (FF) permits (Class "F" dischargers). All food facilities will be classified as Class "F" dischargers.
