No equipment shall be operated in a flowing stream at any time except as may be necessary to construct the dewatering system or divert water flow around the work site. 2.6 Decontamination of Clothing and Equipment. To prevent the spread of aquatic diseases, such as ranavirus, and invasive aquatic species, such as quagga mussel, Permittee shall decontaminate waders, boots and other clothing that will come in direct contact with the water. Decontamination of clothing and equipment shall be done through one or more of the following methods: • Drying equipment in an upland location following last aquatic use. If average daytime temperatures exceed 80° F, drying times shall be at least 7 days. If average daytime temperatures are below 80° F, drying times shall be at least 30 days; • Scalding water wash (at least 140° F) with varying high and low pressure spray to dislodge pathogens, vegetation, and contaminated sediment; • Freezing at a temperature of less than 32e F for more than 72 hours; and/or 2.7 • Soaking in a hospital -grade disinfectant solution for at least two minutes (or longer, based on product directions). To avoid harm to non -target species, disinfected clothing and equipment shall be thoroughly rinsed in a water bath before entering the stream. Repeat decontamination is required only if the equipment/clothing is removed from the site, used within a different waterbody, and returned to the project site. Decontamination shall take place in an upland location, and any chemicals used during decontamination shall be prevented from entering water bodies or stormwater drains. Permittee shall submit to CDFW for written approval, the names and resumes of all qualified biologists and biological monitors involved in conducting surveys and/or monitoring work.
