No person shall discharge, or cause or allow to be discharged, any stormwater, surface water, groundwater, roof runoff, subsurface drainage, cooling water or unpolluted industrial process waters into any sanitary sewer. Stormwater and all natural unpolluted water shall be discharged to such drains as are specifically designated as storm drains, or to a natural outlet approved by the City. Industrial cooling water or unpolluted process waters may be discharged, upon approval of the City, into a storm drain.

When the City determines that it is necessary to modify or eliminate wastes or portions of wastes that are harmful to the structures, processes or operation of the wastewater system, or persons using or operating the system, the discharger shall provide, operate and maintain at his or her expense such pretreatment or processing facilities as may be determined by the City necessary to eliminate the harmful aspects of the discharge.
B. 
Plans, specifications and any other pertinent information relating to the proposed pretreatment facilities or discharge shall be submitted for the approval of the City and, when required by the City or any other authority, by the California Regional Water Quality Control Board or the United States Environmental Protection Agency. No premises and no new facilities may be connected to the public sewer, and no harmful discharge commenced until such approval or approvals are obtained in writing.
C. 
When pretreatment facilities are provided, whether or not required, they shall be maintained continuously in satisfactory and effective operation by the discharger.
D. 
Pretreatment facilities and operations shall comply with applicable Pretreatment Standards and Requirements by Industrial Users as specified by Title 40 Section 403.8(f)(1)(I) of the Code of Federal Regulations.

All interceptors, whether or not required, shall be of a type and capacity approved by the City, and shall be located as to be readily and easily accessible for cleaning and inspection.
B. 
The City shall notify any discharger when it has determined that an interceptor is necessary, and the discharger shall construct and place into operation the interceptor within 120 days. Plans, specifications and other pertinent information relating to a proposed interceptor shall be submitted for approval by the City.
C.

They shall be of substantial construction, watertight, and equipped with easily removable covers which, when bolted in place, shall be gaslight and watertight.
D. 
When a required interceptor is provided, it shall remain continuously in satisfactory and effective operation by the discharger, at his or her expense. An interceptor is not considered properly maintained if it does not intercept and hold all sand, oil or grease, or other constituent involved. No wastewater from public facilities shall pass through the interceptor prior to discharge to the public sewer.
(Ord. 164 Div. 3 §5, 1977)
No person shall cause the discharge of a slug into the public sewer.

Wastestreams with a closed cup flashpoint of less than 140 degrees Fahrenheit or 60 degrees Centigrade using the test methods specified in 40 Code of Federal Regulations 261.21.
2. 
Solid or viscous pollutants in amounts which will cause obstruction to the flow in the City's sewer system and/or wastewater treatment plant resulting in interference.
3. 
Any pollutant, including oxygen demanding pollutants (BOD, etc.) released in as discharge at a flow rate and/or pollutant concentration which will cause interference with the City's sewer system and/or wastewater treatment plant.
4. 
Heat in amounts which will inhibit biological activity in the City's sewer system and/or wastewater treatment plant resulting in interference, but in no case heat in such quantities that the temperature at the City's treatment plant exceeds 40 degrees Centigrade, unless authorized by all relevant government agencies.
B. 
The City Engineer shall develop these limits within 6 months of the effective date of the ordinance codified in this chapter.
