Section 303(d) of the Clean Water Act requires states to identify water that is impaired by pollution, even after application of pollution controls. For those waters, states must establish a total maximum daily load of pollutants to ensure that water quality standards can be attained. This report contains background information, implementation, and issues for Congress as relating to the Clean Water Act.

AbstractMercury is a naturally occurring element that bioaccumulates due to its tendency to associate with organic
matter. Thus methylmercury, the organic (and most toxic) mercury form, will bioaccumulate up the food
chain, with the largest aquatic concentrations found in predatory fish. Five segments of the lower Savannah River
were listed on the state of Georgia's 2000 Section 303(d) list of impaired waters because mercury
in certain species of fish tissue exceeded fish consumption (the primary human route of exposure)
guidelines. Consequently, EPA developed a Total Maximum Daily Load (TMDL) for total mercury for the
middle/lower Savannah River. An Army installation, located in the affected watershed and identified as a
significant mercury contributor, was allowed a 7.43E‐06 kg/yr wasteload allocation (WLA) of
discharged mercury. In lieu of end‐of‐pipe sampling, the installation chose development and
implementation of a mercury minimization plan (MMP) for TMDL compliance. This article describes the
methodology used for MMP development and summarizes the policies, procedures, and guidelines used to reduce
and/or eliminate mercury‐containing discharges into the wastewater collection system. © 2003

The Citarum River is a strategic river in Indonesia, but has poor water quality. The existing pollution control program has no impact on the river's water quality, because it uses a regulatory approach and prioritizes industrial sources. To improve the quality of the river, every pollutant source needs to reduce the pollution load discharged into the river based on the ability of the river to receive pollution. The purpose of this study was to measure pollution load allocation based on the total maximum daily load (TMDL) of the river. The results show that non-point sources contribute the highest pollution load (85%) compared with point sources (15%). The results of the measurement of pollution load allocation showed that the highest contribution of pollution load was from domestic waste (83.5%), followed by industrial waste (6.6%). The target of pollution load reduction for domestic sources is 81.8%, and for industries is 79.5%. The improvement of river water quality should be started at tributaries and domestic sources. This study can be used by local governments to develop water pollution control programs, for instance as a basis for determining the wastewater discharge permit of pollutant sources and permit trading.
