Milk 25 5 = 4 - Earth embankment. The design height of the embankment shall be increased by the amount needed to insure that the design top elevation will be maintained ( ` after settlement. This increase shall not be less than 5 percent. The minimum top width shall be 8 feet. The combined side slopes of the settled r embankment shall not be less than 5 horizontal to 1 vertical . All areas under embankments should be stripped to remove vegetation and un- _ suitable materials before placing fill . When fill heights will exceed 10 feet,. cutoff trenches will be installed under the embankments. ,For ponds with a drainage area, the minimum elevation of the top of the settled embankment shall be 1 foot above the elevation of the water surface during the 25-year, 24-hour emergency spillway storm occurring when the design - - - r volume is filled. For ponds without a drainage area, the minimum elevation of the settled top shall be 1 foot above the design volume. , . - - , . - ,--- Disposal facilities. Waste shall be removed from storage vand used dsor sd of at locations, times;- rates, and volumes shown in the o dlmanage- ment plan without polluting the surface or ground water. to remove and apply Waste ma be i liquid, slurry, or solid, and proper equipment must be available it to the land. --- If polluted runoff is stored, liquids shall be removed promptly to insure that sufficient capacity is available to store runoff from subsequentostor s. from e maximum allowable emptying time shall be based on subsequent storms and on the capacity of the disposal area. Provisions shall be made for •removing solids from storage ponds to preserve _ _- the storage capacity. The method of removal must be considered in planning, C n determining the size and shape of the pond. For ponds built particularly - to store runoff and waste water, an entrance ramp having a slope of 4:1 or flatter may be used. For those built to store slurry and solid waste, some 4 type of emptying facility must be provided. It may be a dock, a pumping platform, a retaining wall , or a ramp having a slope of 7:1 or flatter. Protection. If the waste storage pond creates a safety hazard,fitmshall be fenced and warning signs posted to prevent children for other than the intended purpose. The embankment and surrounding areas _ _ shall be vegetated to control erosion. Vegetative sceens or other me iodsove should be used as necessary to shield the pond from p e visual conditions. Normally no vegetative screening is necessary if the [ surface of the pond when full cannot be observed from a public view. USDA-SCS-Wisconsin Section IV Technical Guide 10/83
