Long <br />Division Dueclor <br />1 have completed the review of Mr. Stover's as-built drawings for the treatment pond and find them to <br />be in compliance of our rules and regulations. There does exist one small problem which can more than <br />likely be attributed to the contours being displayed at a 2 foot interval rather than a I foot interval. In <br />Mr. Stover's letter to you, he states "The treatment pond will be at least feet above finished grade to <br />prevent surface run-off from entering the pond." At [he south east corner of the pond, where the ditch <br />drains into [he pond, the contours do not clearly indicate that this is the case. Theoretically, the <br />embankment can be anywhere from just over 0" to just under 4'. I am relatively positive that [here <br />exists at least 2 ` of embankment, however i[ cannot be verified by [he as-built drawings. <br />
