About this file
This is a technical design drawing set for water management and remediation infrastructure associated with GCI Permit No. 4105 for the Pollyanna #2 AMD project located in Latimer County, Oklahoma. The project is under the jurisdiction of the Office of Surface Mining Reclamation and Enforcement (OSMRE), U.S. Department of the Interior, Tulsa Field Office.
The design encompasses multiple water treatment and conveyance components including a Floodless Basin (FLB) pond, Oxidation (OXI) pond, wetland outlet system, and associated channels. Key specifications include the FLB Channel (14.00 SQ FT × 450 LF = 233.33 CY × 1.5 ton/cy = 350 tons), OXI Pond Outlet Channel (6.50 SQ FT × 210 LF = 51 CY × 1.5 ton/cy = 76 tons), Wetland Outlet Channel (6.50 SQ FT × 50 LF = 12 CY × 1.5 ton/cy = 18 tons), and FLB Auxiliary Spillway (6.50 SQ FT × 30 LF = 7 CY × 1.5 ton/cy = 11 tons). Infrastructure also includes seep spreaders and channel flow spreaders with specific concrete specifications (F'c 3,500 psi Type II) and steel reinforcement requirements using welded wire mesh. The plan view and general layout drawings show the spatial arrangement of the wetland, OXI pond, and FLB systems with detailed elevation profiles and coordinate data. Drawing date is 8/5/2026, with design and checking attributed to EPS and MRB respectively.
