SUPPLEMENTARY INFORMATION: Back to Top

On March 10, 2006, EPA Region 6 made a commitment to the EPA Headquarters Office of Water under EPA's National Water Program Fiscal Year 2006 Guidance for the program activity measure (PAM) number WQ-12, to establish or approve a total of 188 TMDLs in fiscal year (FY) 2006. Under the PAM number WQ-12, EPA expected the Oklahoma Department of Environmental Quality (ODEQ) to develop a total of 87 TMDLs in fiscal year (FY) 2006 and submit them for EPA's approval. By the end of July 2006, ODEQ had submitted two final TMDLs for EPA's approval and 30 draft TMDLs for EPA's review and comments. EPA has approved the two final TMDLs submitted by ODEQ. However, a recent discussion between EPA Region 6 and ODEQ senior managers determined that although substantial progress has been made on the other TMDLs, the remainder of the TMDLs needed to meet the commitment could not be completed by the target date. Accordingly, EPA Region 6 has decided to conduct the public participation process for these thirty TMDLs and establish the final TMDLs.
