As such a low-level outlet capable of draining all storage must be insta!!ed on <br />the dam and water must be released from the runoff control structures within twenty- <br />fourhours or as directed by the dr`vision engineer and/or water commissioner. <br />we appreciate your comr?ent, and incorporated your request into our adequacy review we are <br />confident that the amended design provided by ACC will satisfy your request for a low®level cutlet to <br />allow for ?vater to be released within ?4 hours. The design incorporates two open ended "T'" discharge <br />pipes with slotted risers; the lower open pipe is atthe bottol of the structure see the profile drawing <br />in the attachment, which vas included in both amended revisions.
