Notification #1600-2018-0342-R3 Streambed Alteration Agreement October 28, 2019 Page 14 of 24 deployed. Project activities shall not cause turbidity increases in surface water to exceed: • Where natural turbidity is less than 1 Nephelometric Turbidity Units (NTUs), controllable factors shall not cause downstream turbidity to exceed 2 NTU; • Where natural turbidity is between 1 and 5 NTUs, increases shall not exceed 1 NTU; • Where natural turbidity is between 5 and 50 NTUs, increases shall not exceed 20 percent; • Where natural turbidity is between 50 and 100 NTUs, increases shall not exceed 10 NTUs; • Where natural turbidity is greater than 100 NTUs, increases shall not exceed 10 percent. In determining compliance with the above limits, appropriate averaging periods may be applied provided that the Qualified Biologist, Biological Monitor, or CDFW determine that aquatic life will be fully protected. Averaging periods may only be used with prior permission of CDFW. <2.1 Staging and Storage Areas. Construction equipment, building materials, fuels, lubricants and solvents shall not be stockpiled or stored where they could be washed into State waters or where they will cover aquatic or riparian vegetation. 0 Equipment over Drip Pans. Stationary equipment such as motors, pumps, generators, compressors and welders, located within or adjacent to the stream and riparian areas shall be positioned over drip -pans. 2. Check Equipment for Leaks. Any equipment or vehicles driven and/or operated adjacent to the stream and riparian corridor shall be checked and maintained daily by the Permittee and their contractors to prevent leaks of materials that if introduced to water could be deleterious to aquatic life, wildlife or riparian habitat. Vehicles shall be moved away from the stream prior to refueling and lubrication. 1) Hazardous Materials. Any hazardous or toxic materials that could be deleterious to aquatic life that could be washed into State waters or their tributaries shall be contained in watertight containers or removed from the project site. 2.15 Imported Materials. Permittee shall not import, take from or move any rock, gravel, and/or other materials within Atherton Cove, Smith Canal or the San Joaquin River, their streambeds or banks except as otherwise addressed in the Project Description. 2.16 Debris and Waste Disposal. Permittee shall not dump any litter or construction debris within the project area. All such debris and waste shall be picked up daily and properly disposed of at an appropriate site. Upon completion of operations and/or onset of wet weather, all construction material and/or debris shall be removed from the project work site to an area not subject to inundation. All
