Element 3 -TMDL Implementation

States are not required under Section 303(d) of the Clean Water Act to develop TMDL implementation plans and EPA does not approve or disapprove them. However, the department will develop and make available for public comment an implementation strategy in conjunction with development of a TMDL. This implementation strategy will provide information regarding how point and nonpoint sources can or should be controlled to ensure implementation efforts achieve the loading reductions identified in the TMDL. Any management practices already in place or being developed in the watershed to eliminate the impairment, if known, will be included in the TMDL implementation strategy document.

In general, point source reductions are typically implemented through discharge permits administered through the Missouri State Operating Permit program to meet the requirements of Missouri's Water Quality Standards and the National Pollutant Discharge Elimination System (NPDES). Because the department does not regulate nonpoint sources, nonpoint source loading is typically reduced through the use of best management practices that may be implemented to address and improve land use practices that may contribute pollutants to the impaired water bodies. Grant money from the department's Section 319 Nonpoint Source Implementation Program, and the Soil and Water Conservation Program (for cost-share practices) may also be available for implementing nonpoint source controls in the watershed.
