* Background
- To meet the challenges of changing environmental conditions led by development pressure from surrounding areas of Lake Shihwa and seawater circulation of tidal power plant, Total pollutant load management system was introduced to pursue improvement of environment in Lake Shihwa
- Partial improvement of water quality was achieved due to establishment and operation of environmental treatment facilities, efforts to reduce land-based pollution load such as industrial sewage treatment, and tidal power plant operation, etc. However, it is necessary to manage pollution from land-based sources systematically to resolve long-term environmental problems
* Legal grounds
- Marine Environment Management Act, Article 15 (3) : Emission Regulation of Pollutant Substances in Special Management Sea Area
- Enforcement Decree of Marine Environment Management Act, Article 11(Enforcement Sea Area of Total Emission Regulation of Pollutant Substance), Article 12(Total Emission Regulation Items of Pollutant Substances, Etc.), Article 13(Allotment, Etc. of Pollution Loading by Business Place), Article 14( Performance Evaluation on Emission Regulation of Pollutant Substances, Etc.), Article 15 (Financial Support, Etc.)
* Implementation Status
- Decided to establish the basis of the total pollutant load management system at the second phase of Lake Shihwa Comprehensive Management Plan (May 2007)
- Established the roadmap to introduce the total pollutant load management system (September 2009)
- Decided to enforce the total pollutant load management system by Lake Shihwa Management Committee
- Organized a working group and an advisory group for total pollutant load management
- Legislated Basic Directions for Lake Shihwa Total Pollutant Load Management(November 2011) andTechnical Guidelines (January 2012)
※ The planning period of the first total pollutant management : 2013~2017
※ Target materials : COD(Chemical Oxygen Demand) and TP(Total Phosphorus) - Established the first basic plan of total pollutant load management in Lake Shihwa special management sea area (December 2012)
※ Water quality target : COD 3.3mg/L, TP 0.065mg/L
※ Divided inner Lake Shihwa into upstream, midstream, and downstream considering water qualityin a distribution system, data availability of water quality measurement, distribution of pollutantsources and water quality status. Set up a water quality target in the downstream making the most out of available water quality data, and monitor water quality in the upstream
- Developed and implemented the first action plan of total pollutant load management in Lake Shihwa Special Management Sea Area (July 2013)
