Please include this supplemental information in those packages for your review. The areas of wetness in the table below were discovered since the last permit application update and were sampled, where determined necessary and possible, in accordance with the Riverbend Plan for Identification of New Discharges (8 May 2015 version). AOW LO Location Coordinates' Description latitude Longitude Water trickles from the bank and sits in a pool.There is a small natural berm that S-23 35.217994 -81.750208 keeps the water from the river.If the water overtopped the berm,it would flow via a short conveyance to the Broad River. 5-24 35.218139 -81.749428 Water trickles from the bank and flows toward to the Broad River. Water emerges from the ground,flows about 30 feet toward the Broad River,and S-25 35.217689 -81.751894 then enters a sand bank.The water does not reach the river via a discrete conveyance. S-26 35.217425 81.753931 A diffuse wet area on the sandy bank of Suck Creek.Soggy ground noted but no discernible flow except for drainage at edge of bank. _ 5-27 35.21383 81.756478 Water emerges from bank and immediately meets the sandy creek bed of Suck Creek. 5-28 35.211677 81.753876 A diffuse wet area on the bank of Suck Creek.Soggy ground noted but no discernible flow except for drainage at edge of bank. S-29 35.211542 81.753993 A diffuse wet area on the bank of Suck Creek.Soggy ground noted but no discernible flow except for drainage at edge of bank. 5-30 35.211496 81.75391 A diffuse wet area on the bank of Suck Creek.Soggy ground noted but no discernible flow except for drainage at edge of bank. S-31 35.211482 81.753887 A diffuse wet area on the bank of Suck Creek.Soggy ground noted but no discernible flow except for drainage at edge of bank. 5-32 35.211258 81.753646 A diffuse wet area on the bank of Suck Creek.Soggy ground noted but no discernible flow except for drainage at edge of bank. _ 5-33 35.218272 -81.754754 A diffuse wet area on the sandy bank of the Broad River.Dry at time of sampling A diffuse wet area on the sandy bank of Suck Creek.Soggy ground noted but no S-34 35.217556 -81.753725 discernible flow except for drainage at edge of bank. 1.Location coordinates(degrees)for AOW sampling locations are approximate and are in NAD 83 datum. • ' Poupart March 7, 2016 Page 2 of 2 Attached are the analytical data for these areas of wetness as well as a map that indicates the locations of these areas of wetness. Flow measurements and analytical samples were collected on 08 February 2016. No flow was evident at S-33 on 08 February 2016; therefore, no samples were collected. S-34 was sampled 01 March 2016, and we will supplement this update with the data once it becomes available.
