Except as provided in Section 15.12.210, it shall be unlawful for any person to make or cause to be made any Non-stormwater discharge into the County storm drain system or directly to natural surface waters.

(SCC 1280 § 2, 2004)
Notwithstanding the exemptions provided for in Section 15.12.210 above, if the Regional Board or the Administrator determines that a discharge which is otherwise exempt from the prohibition on discharges causes or significantly contributes to the violation of any receiving water limitation or results in the conveyance of significant quantities of pollutants to natural surface waters, or is otherwise a danger to public health or safety, the Administrator may give written notice to the owner or operator of the facility that the discharge exception shall not apply to the discharge at issue following expiration of the 30 day period commencing upon delivery of the notice. Upon expiration of such 30 day period, any such discharge shall be unlawful. Upon finding that any continuance of the discharge poses an immediate significant threat to the environment or to public health and safety, the Administrator may waive the thirty day waiting period and require immediate cessation of the discharge.
(SCC 1280 § 2, 2004)
It shall be unlawful for any person to discharge, or cause to be discharged, any stormwater or material to the County storm drain system which results in, or contributes to a violation of a receiving water limitation or a violation of the Municipal Stormwater Permit.
(SCC 1280 § 2, 2004)

Notwithstanding the provisions of this section, any person who maintains an illicit connection, as defined in Section 15.12.130, may apply to the County for a Sacramento County Water Agency Permit to continue the connection subject to applicable County standards. No permit shall be issued for any connection or any physical facility or apparatus that is installed, intended, serves, or is known to convey a prohibited discharge to the County storm drain system or waters of the State.
(SCC 1280 § 2, 2004; SCC 1295 § 3, 2005)
A violation of the provisions of this Article shall occur irrespective of the negligence or intent of the violator to construct, maintain, operate or utilize an illicit connection or to cause, allow or facilitate any prohibited discharge.
