“…The major policies include implementation of Total Maximum Daily Load (TMDL), riparian buffer zones, land acquisition, and a water use charge to support the program's efforts. The MOE is aggressively pursuing the implementation and compliance with TMDLs for watershed protection, and effective control of NPS is believed to be the key method for successfully meeting the TMDLs (Jung et al 2008). New techniques, applying the concept of sustainable development and trying to cause no increasing impacts in the hydrologic cycle, are now being developed.…”

Nonpoint source pollution management initiated by the Ministry of Environment (MOE) in Korea resulted to the construction of 25 pilot facilities termed Best Management Practices (BMPs) until 2005. The national nonpoint sources control projects were employed to fulfill the Total Maximum Daily Load programs. The long-term monitoring being conducted at the sites which began in 2006 is providing detailed insight into the performance of the BMPs. The experience and performance data will be used to better understand and implement similar structural BMPs in the future as well as to assist the MOE in developing the design and maintenance guidelines of BMPs. This study presents the results gathered from the monitoring field tests and experiments over 22 rainfall events between the June 2006 and September 2008 period investigating the pollutant removal efficiency of the infiltration trench BMP that is one of the 25 pilot projects of the MOE. In addition, it includes the development of simple linear regression models to estimate constituent event mean concentration. The results reveal high treatment efficiencies for total suspended solids (89%); biochemical oxygen demand, chemical oxygen demand, and dissolved organic carbon (89-93%); oil and grease (100%); cadmium, lead, and zinc (89-93%); total nitrogen (84%); and total phosphorus (82%). The monitoring data and results will represent a step forward to a better prediction of impacts in the environment and to the national development of BMPs for sustainable watershed management in the country.

“…There exist established programs leading to the development of BOD TMDLs for four major rivers, but observations show BOD concentrations are consistently above 10.0 mg/L. As part of the Comprehensive Measures for Non-point Source Pollution Management actions, pilot projects have been established for nonpoint source (NPS) pollution control (Jung et al, 2008). Results from these pilot projects will guide the second phase -implementing NPS best management practices (BMPs) at the watershed scale.…”

“…National efforts have been directed towards establishing point source controls at several locations including wastewater treatment facilities. However, water quality has not improved substantially and attention has expanded to include control of nonpoint source pollution in watershed management efforts (Kim and Yi, 2006;Jung et al, 2008). In 1999, the Korea Ministry of Environment (MOE) focused attention on the Han, Nakdong, Geum, and Yeongsan/Sumjin Rivers, four major rivers providing municipal and industrial water needs for nearly 80% of the population of Korea.…”

This paper presents advancements to the approach for Total Maximum Daily Load (TMDL) development in Korea. The current Korean TMDL process does not directly consider uncertainty and it does not include an objective approach to allocate pollutant load reductions. This paper develops a methodology to address uncertainty by incorporating a margin of safety (MOS) based on three approaches: judgment, standard error of loading characteristics, and uncertainty and variability of loading characteristics. In addition, three pollutant load reduction allocation approaches are compared to assess their impact: equal load, equal percent, and equity standard reductions. These two proposed additions to the TMDL process in Korea are demonstrated for a BOD TMDL development in the Anyangcheon Watershed. The results confirm the importance of incorporating uncertainty into the TMDL process and clearly illustrate the significant differences in TMDL and load allocation produced when using different approaches to estimate the MOS. Further, the comparison of the three load allocation strategies highlights the potential limitations of equal load and equal percent reduction approaches. The use of technical expert and decision maker ranking of factors create an equitable and sustainable load allocation among the sub-watersheds. It can be concluded that incorporating uncertainty and providing an objective load allocation strategy are essential elements needed for future TMDL development in Korea.
