PUBLIC NOTICE
February 2, 2015
REQUEST FOR PUBLIC COMMENT ON A PROPOSED MODIFICATION TO OKLAHOMA’S
WATER QUALITY MANAGEMENT PLAN FOR THE
TOWN OF POCOLA WASTEWATER TREATMENT FACILITY
Public Comment Period Begins:
February 2, 2015
Public Comment Period Ends:
March 19, 2015
Permitee: Pocola Municipal Authority, P.O. Box 397, Pocola, OK 74902 [Facility Legal
Description: N½ Section 5, Township 9 North, Range 270 East I.M. in LeFlore County]
Receiving waters and location: Poteau River (Latitude: 35o 16’ 53” North; Longitude: -96o
28’ 08” West)
The Town of Pocola’s Wastewater Treatment Facility has requested permission to move
their discharge location from a tributary to Cedar Creek to the Poteau River in addition to
increasing their current design flow from 0.275 MGD to 0.55 MGD. The Town of Pocola is
located in the Poteau watershed in LeFlore County.
The Oklahoma Department of Environmental Quality (DEQ) conducted a waste load allocation
(WLA) study for the Town of Pocola. A waste load allocation is the maximum amount of
pollutants in treated wastewater that can safely be discharged into a waterbody without
adversely affecting its quality. DEQ, along with the U.S. Environmental Protection Agency
(EPA), has evaluated the Poteau River to develop these recommended maximum amounts
that may be discharged into it with a design flow of 0.55 MGD:
Year round:
30 mg/L BOD5 (5-day biochemical oxygen demand)
30 mg/L TSS (total suspended solids)
The comment period will be open for 45 days. If you have any concerns regarding these proposed
limits, please submit your comments in writing by the end of the workday on March 19, 2015 to:
David Akakpo
Water Quality Division
Oklahoma Department of Environmental Quality
P.O. Box 1677
Oklahoma City, OK 73101-1677
(405) 702-8197
E-mail: [email protected]
You may also request a public meeting in writing. If there is a significant degree of public interest,
DEQ will schedule a public meeting.
After evaluating comments received and making any
necessary changes, the WLA will be submitted to the U.S. Environmental Protection Agency (EPA)
for final approval.
