u I I 11 11 0 u "A map showing the existing topographical contours of the property and proposed final elevations of the completed disposal site. The plan can be used for this purpose. The approximate depths of cuts, trenches, ponds, etc., should be shown on this map. The final elevations should repre- sent the ultimate grading or closure plan." SECTION 17616(i) "Information on the underlying soils, geology, and ground water occurrence, based on test borings conducted on the property. Show the locations of test borings on the plan. Described surface and cover soils using the Unified Soils Classification System (USCS). Test borings must extend at least 5 feet below the depth of the proposed disposal area. Soils, geology, and ground water data must be provided by qualified staff or consultants." SECTION 17616(j) SITE DRAINAGE "Description of all surface and subsurface drains which are to be used to control water from areas on, or adjacent to, the disposal site. The location and type of protective dikes, berms and levees shall be described." "The locations of primary drains, berms, etc., should be shown on the plan. The design basis of drainage control devices is to be given; this may require determining typical runoff coefficients and runoff volumes for 100 -year flood conditions." SECTION 17616(k) LEACHATE SYSTEM "If leachate generation is anticipated, described the method of monitoring, collection, treatment, and necessary dis- posal." "If leachate barriers are proposed, describe their length, width, depths, and design characteristics. Show the loca- tion on the plan. Describe monitoring and sampling proce- dures. Indicate whether barriers are in place or to be in- stalled. Estimate the volume of leachate to be handled and the manner of removal from the control barrier system (e.g., periodic pumping). Indicate the manner of treatment and point of discharge for treated leachate." N Section 7.2 Section 8.0 Section 9.0 Section 10.0 Rev. 0 July 19, 1989
