All non-structural BMP materials (e.g., training documents, compliance tracking procedures) must be ready for use at the start of construction. • Construction material, debris, rubbish, spoils, soil, silt, sawdust, rubbish, steel, welding, slag, welding rods, waste material, waste containers, other organic or earthen material, or any other substances which could be detrimental to water quality or hazardous to aquatic life that is discharged as a result of project related activities shall be prevented from entering waters of the State. Spoils from excavations shall not be stored in waters of the State. • Environmentally sensitive areas and environmentally restricted areas, including any avoided waters of the State, must be clearly identified in the field for exclusion prior to the start of construction. Such identification must be properly maintained until construction is completed and the soils have been stabilized. Equipment, materials, or any other substances or activities that may impact waters of the state outside of the limits of project disturbance are prohibited. • The number of access routes, number and size of staging areas, and the total area of the activity must be limited to the minimum necessary to achieve the project goal. Routes and work area boundaries must be clearly demarcated. • The limits of project disturbance must be clearly identified in the field prior to start of construction activities within waters of the State. Such identification must be properly maintained until construction is completed and the soils have been stabilized. Equipment, materials, or any other substances or activities that may impact waters of the state outside of the limits of project disturbance are prohibited. Toxic and Hazardous Materials • Activities permitted under this General Order shall not discharge substances in concentrations toxic to human, plant, animal, or aquatic life or that produce detrimental physiological responses. • Discharge of unset cement, concrete, grout, damaged concrete spoils, or water that has contacted uncured concrete or cement, or related washout to surface waters, ground waters, or land is prohibited. If concrete washout is necessary at a site, washout containment to prevent any discharge shall be used. Wastewater may only be disposed by delivery to a sanitary waste water collection system/facility (with authorization from the facility's owner or operator) or a properly licensed disposal or reuse facility. • Appropriate BMPs must be implemented throughout project activities to prevent and control potential leaks/spills/drainage of potentially hazardous materials such as: petroleum 6.G. - Page 10 of 45 188
