(a) A spill response plan for hazardous waste, hazardous materials and uncontained construction materials shall be prepared and available at the construction sites for all projects where the proposed construction site is equal to or greater than one acre of disturbed soil and for any other projects for which the city engineer determines that a plan is necessary to protect surface waters. Preparation of the plan shall be in accordance with guidelines published by the city engineer.
(b) A storm water pollution prevention plan shall be prepared and available at the construction sites for all projects equal to or greater than one acre of disturbed soil and for any other projects for which the city engineer determines that a storm water management plan is necessary to protect surface waters. Preparation of the plan shall be in accordance with Chapters 16.28 and 16.11 of this code and with guidelines published by the city engineer.
(c) Prior approval shall be obtained from the city engineer or designee to discharge water pumped from construction sites to the storm drain system. The city engineer or designee may require gravity settling and filtration upon a determination that either or both would improve the water quality of the discharge. Contaminated groundwater or water that exceeds state or federal requirements for discharge to navigable waters may not be discharged to the storm drain system. Such water may be discharged to the sanitary sewer system, provided that the requirements of Section 16.09.040 are met and the approval of the superintendent is obtained prior to discharge. The city shall be compensated for any costs it incurs in authorizing such discharge, at the rate set forth in the municipal fee schedule.
(d) No cleanup of construction debris from the streets shall result in the discharge of water to the
storm drain system; nor shall any construction debris be deposited or allowed to be deposited in the storm drain system.
