The term “work” means any ground disturbing activities in any delineated waters of the state that are permitted under this General Order, regardless of the presence or absence of flowing or standing water. Stormwater For ground disturbing activities that do not require enrollment in Order No. 2009-0009-DWQ, project plans included with the NOI shall include the appropriate erosion and sediment control and stormwater management conditions described below. • Erosion and Sediment Control ○ No later than 24 hours prior to the start of a likely rain event, the discharger shall ensure that disturbed areas that drain to waters of the state are protected with correctly installed erosion control measures (e.g., jute, straw, coconut fiber erosion control fabric, coir logs, straw, etc.) or revegetated with propagules (seeds, cuttings, divisions) of locally collected native plants. The likely rain event is defined as any weather pattern that is forecast to have a 50 percent or greater probability of producing precipitation in the project area. The discharger shall obtain on a daily basis a printed copy of the precipitation forecast information (and keep for record) from the National Weather Service Forecast Office. • Stormwater Management: ○ Disturbed areas must be temporarily stabilized to prevent erosion and accidental discharge into waters of the state no later than 24 hours prior to any likely precipitation event. A likely precipitation event is any weather pattern that is forecast to have a 50 percent probability of producing precipitation in the project area, as predicted by the National Weather Service. If commencement of a precipitation event is predicted to begin less than 24 hours after the forecast is issued, temporary stabilization of the disturbed in-water work areas must begin immediately. ○ No individual construction activity that could discharge sediment or other pollutants may be initiated if that activity and its associated erosion control measures cannot be completed prior to the onset of precipitation. After any rain event, the discharger shall inspect all sites currently under construction and all sites scheduled to begin construction within the next 72 hours for erosion and sedimentation problems and take corrective action as needed. Seventy-two hour weather forecasts from the National Weather Service shall be consulted prior to start-up of any phase of the project that may result in sediment-laden runoff to the project site, and construction plans made to meet this condition.
