§ 1790-080. EXCEPTIONS TO CONDITIONALLY ALLOWED NON-STORMWATER DISCHARGES

Notwithstanding the conditionally allowed discharges provided for in Section 1790-070, if the Regional Board or the Director determines that a discharge which is otherwise allowed causes or significantly contributes to the violation of any Receiving Water Limitation or results in the conveyance of significant quantities or concentrations of pollutants into the County storm drain system or to natural surface waters, or is otherwise a danger to public health or safety, the Director may give written notice to the discharger that the 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 discharge poses an immediate significant threat to the environment or to public health and safety, the Director may waive the 30-day waiting period and require immediate cessation of the discharge.
