changed the direction of water quality policy from regulations on the size of developed areas to the amount of water pollutants. In January 2009, the government allowed areas with the TMDL system to carry out development projects regardless of the scale of the projects if they meet the TMDL standard. The environmental protection areas in the Seoul metropolitan area are famous for their beautiful landscapes and closeness to large cities. Therefore, with the eased regulations on those areas, investment is expected to increase in creating large tourist areas. Discharge of industrial wastewater Under the past regulation, building factories was banned within a certain distance from the upstream areas of water source. As a result, wide areas near the water source (at maximum of 20 km from the point of collecting water) were strictly controlled. But some expressed concern that the regulation is too strict for plants discharging only pollutants similar to sewage from households. To solve that problem, the government revised relevant laws in December 2008. It eased the regulation on factories that meet certain standards such as not discharging industrial waste waster and treating all emitted sewage through public sewerage system. So the limit on distance was reduced to 7 km upstream from water collection sites. Advanced air pollution management To control air pollutants more effectively, Ministry of Environment introduced the Telemetry Monitoring System (TMS) on the smokestacks of plants in 1997, and Total Air Pollution Load Management System in 2007. TMS and Total Air Pollution Load Management System have been recognized as advanced systems in that TMS enables real-time monitoring of the concentrations of air pollutants and Total Air Pollution Load Management System encourages effective management of air pollution in places of business through a quota system. However, the two systems put economic burdens on companies. Therefore, the government has come up with measures to reduce such burdens without undermining the effectiveness of the systems. First of all, improvements made on Total Air Pollution Load Management System include: the allocation of the quota on dust has been suspended as it is difficult to set the quota because dust varies in types and characteristics. currently the government is going to exclude Type 3 plants (mid-sized plants) from the system by revising relevant laws as those plants emit few air pollutants. Next, some changes were made on TMS System as follows: Installing and managing TMS device is expensive. So the
