7 ` /~ III IIIIIIIIilllllll ~ / ~-~ ~ 999 CHECKLIST FOR SEDIMENTATION POND AS-BUILTS v~ C This is a checklist of required and preferred items to be on a sedimentation pond as-built. Technically, an as-built is a representation of all physical features of the structure. Horizontal features of size and configuration (including contour lines) are shown on a plan view. Vertical aspects are often, and better, shown on cross-sections or profi]e drawings. Text specifications often appear on an as-built. Operational features of a pond are required to demonstrate compliance with the Rules, and these items are best illustrated (operational design requirements) on an as-built drawing. As-builts should confirm that a structure is built according to an approved design. Designs are based on studies, investigations, and demonstrations, and need to demonstrate general compliance with Rule 2.05.6(3). Required design aspects that do not appear on an as-built need [o be presented elsewhere in the Permit. Inclusion on the as-built often eliminates duplication of inforniation in the Permit by presentation of design, as well as as-built, features on a single drawing. As a matter of practicality, as-built drawings are frequently annotated design drawings. Pond # MB 4 ,Permit C-_80_-_007_, date:_~ Feb 1999 ITEM REFERENCE PURPOSE COMPLIANCE?

A controversial item dewatering device the primary spillway of the rule. The "or" of the by debris. rules cou]d be interpreted that such devices are not required on conduit spillways. In any event, use is a good engineering practice. Invert elevation of the 4.05.6(3)(c) Required [o determine DISCREPENCY.
