Examples of standard surfacewater control facilities, along with design procedures fortheir selection, design and construction, are provided inthe Engineering Field Manual for Conservation Practicespublished by the US Department of Agriculture, SoilConservation Service (SCS). Examples of conveyancefacilities used for run-on and runoff control at hazardouswaste units are shown in figures 6-6 through 6-8 anddescribed below. These figures show grass areas withslopes of 2:1; note, however, that any vegetated finalslope areas to be tractor mowed should have slopes nogreater than 3:1.2) Examples of barrier conveyance anddetention/retention systems include:Barriers:Conveyance:Detention/retention:berms, dikesswales, ditches, channels, pipecross drains and over- side drainswith inlet and outlet appurtenances;pipedrop inlets, hooded inlets, dropand chute spillway structuressedimentation control basinsand run-offretention basinsc. Run-on control systems. Drainage berms,ditches and overside drains or spillways can be selectedand designed to prevent flow onto the active portion ofwaste units during peak discharges from specified returnstorms. Drainage swales and ditches with berms can belocated to intercept and convey water run-on flowsaround hazardous waste sites and around waste unitswithin the site. To reduce the potential for erosion andminimize maintenance, spillways or overside drainsystems should be considered for steep ditch reachesand where collected flows must be carried down slopesfor discharge.(1) If there is any chance that overflows coulddamage constructed elements of waste units or enteractive operation areas, they should be sized for carryingpeak flows from storms with return frequencies upwardsCANCELLED6-15to 100 years. Erosion control measures for theconveyance system should be evaluated and selected tominimize maintenance over the anticipated service life.As described in paragraph 6-5d(2), conveyance systemsdeveloped for the waste unit perimeter to intercept runon may also be used to intercept run off from closedareas, if the surface water does not require retention.
