SEC. 7-806. QUALIFIED DISCHARGE PROHIBITIONS:
The general prohibition shall also prohibit any person from contributing or causing to be contributed, directly or indirectly, the following substances to the City storm drainage system:
A. Any substance which will cause the City to violate its NPDES permit, its State storm water permit, or the applicable receiving water quality standards.
B. Swimming pool water, even if it is dechlorinated.
C. Pollutants to the City storm drainage system in excess of that amount that the Director has determined can be removed to the maximum extent practicable.
Wastes prohibited by this Section shall not be stored in such a manner that they could be discharged to the City storm drainage system. All floor drains located in process or materials storage areas must discharge to the industrial user's wastewater pretreatment facility and shall not be connected to the City storm drainage system. However, the Control Authority may approve temporary discharges of the above-enumerated substances to the City storm drainage system when no reasonable alternative method for disposal is available.

SEC. 7-810. CERTIFICATE OF EXEMPTION:
The Director may issue a certificate of exemption from the annual sampling requirements of the California General Industrial Permit to any user upon application. If an industry can demonstrate that it has implemented BMPs and has eliminated onsite risks of storm water pollution, that industry may be granted an exemption from sampling. The specific criteria for exemption will be developed by the City and approved by the Regional Water Quality Control Board ("RWQCB") prior to implementation of the program. The filing or granting of a certificate of exemption shall not relieve the user from its obligation to comply with the following conditions at the time application is made:
1. The user shall develop and implement an effective SWPPP and identify and implement appropriate BMPs for the facility.
2. The user shall make available monitoring data sufficient to substantiate the effectiveness of the BMPs.
3. The user shall meet all requirements of the general permit including certifications regarding elimination of illicit connections.
Users requesting a Certificate of Exemption must submit their NOI and SWPPP to the Municipal Utilities Department with supporting data as appropriate. Applications shall be submitted by May 1 of the year preceding the year for which the exemption is being requested. Applications to renew/extend Certificates of Exemption made by the same user for the same use covered by the previously granted Certificate of Exemption, shall be requested in writing and consist of
(i) visual monitoring and annual inspection reports,
(ii) revisions to the SWPPP,
(iii) annual report to RWQCB, and
(iv) any supplemental data deemed appropriate to support the application, unless otherwise requested by the City.
Certificates of Exemption are issued to a specific user for a specific site, not to exceed five (5) years in duration. A certificate shall not be reassigned, transferred, or sold to a new owner, new user, different premises, or a new or changed operation, and shall not extend to an increase in usage, discharge, or operations by an existing user without the written approval of the City. Any succeeding owner or user shall apply for a sampling exemption certificate sixty (60) days prior to change of ownership or the exemption shall expire.
(Added by Ordinance 013-95 C.S. — Effective date July 26, 1995)

SEC. 7-811. DISCHARGE IN VIOLATION OF PERMIT:
Any discharge which would result in or contribute to a violation of the City's NPDES permit or any amendment, revision, or reissuance thereof, either separately, considered or when combined with other discharges, is prohibited. Liability for any such discharge shall be the responsibility of the person(s) causing or responsible for the discharge, and such person(s) shall defend, indemnify, and hold harmless the City against any claim, expense, liability, or payment for injury or damage to any person or property and shall defend, indemnify, and hold harmless the City in any administrative or judicial enforcement or any legal action resulting from such discharge.
