information be provided and certified to demonstrate compliance within the permit. <br />In order to demonstrate compliance with Rule 4.05.6(3)(c) please include details of the <br />dewatering device. <br />On Pond MB-1 diagram, it is indicated that Merrick drawings C-012, C-013 and C-014 may <br />contain those data, but those do not accompany the MB-1 diagram. The orientation of the drain <br />pipe inlet detail needs to be added, as do details of the baffle and bypass. "there is no description <br />of the nonclogging element of the device. As no profile or description of the elevation of the <br />sediment storage level is provided, a demonstration cannot be made that the dewatering device is <br />not located at a lower elevation. <br />Regarding the Pond MB-4 diagram, only the size and inlet elevation of the dewatering device is <br />indicated. No details of direction, outfall, bends, or other features are shown. There is no <br />information regarding the nonclogging element of the device. As no profile or description of the <br />elevation of the sediment storage level is provided, a demonstration cannot be made that the <br />dewatering device is not located at a lower elevation. The Division requests that the missing <br />information be added to the as-built and certified. <br />4. The as-built should show the dimensions of the spillway systems so that an operation <br />demonstration can be developed. Barriers to piping should be shown. <br />On the MB-l diagram, the emergency spillway may be described on Merrick drawings C-012 <br />and C-015 and the primary spillway on Merrick drawings C-012, C-013, and C-014. Barriers to <br />piping are not shown, if applicable. <br />On the MB-4 diagram, no dimensions are shown other than the diameter of the primary spillway <br />and the invert elevation of the emergency spillway. The grade, width, slopes, and any <br />protective armor of the emergency spillway should be shown. The configuration and length of <br />theprimary spillway should be shown. Piping barriers should be shown if applicable. <br />5. To demonstrate compliance with Rule 4.05.6(4) for the primary and emergency spillway, <br />the as-built should demonstrate the 1-foot separation required. <br />For Pond MB-I, the drawing indicates, again, that some of this information at least is on <br />Merrick drawings which do not accompany the as-built. <br />For Pond MB-4, the included information demonstrates non-compliance with this rule as a <br />separation of only 0.6 feet is indicated. <br />6. To demonstrate compliance within the permit to Rule 4.05.6(1 l)(f), the embankment in- <br />slopes and out-slopes should be shown on the as-built diagrams. These aze not indicated on <br />the diagram for either Pond MB-1 or MB-4. <br />
