The Marine Environment Monitoring and Monitoring Station Establishment Regulations, drawn up in line with Article 9 of this Act, was promulgated on November 11, 2002. These regulations detail the monitoring regulations, standards for the establishment of marine monitoring stations, and sampling and analysis methods each competent authority must follow when pursuing marine environment monitoring work. According to these regulations, marine environment monitoring stations will be positioned at the mouths of all primary and secondary rivers, the outlets of major pollution sources, harbors, lagoons, marine water quality background monitoring points, and at areas designated special areas under Article 15 of the Marine Pollution Control Act, such as nature reserves, ecology conservation areas, and the ecology protection zones of national parks. Monitoring items for each station must be determined based on the particular characteristics of each marine monitoring point and/or the type of pollution source. Basic monitoring items include

1) marine hydrology, such as water current speed and direction,

2) marine water quality, including salinity, pH value, and dissolved oxygen (DO) levels,

3) marine organisms, including plankton, bottom-dwelling organisms, and specially targeted organisms.

The monitoring frequency for each of these basic monitoring items is set at once per season. These regulations also provide legal basis for marine environment water quality sampling methods in order to guarantee the quality of marine environment monitoring data. Furthermore, to protect the public's right to know, each local government competent authority must report their marine environment monitoring results two months after the end of each season.The EPA annul monitoring program has being conducted on water temperature, salinity, pH, DO, SS, nitrate nitrogen, nitrite nitrogen, chlorophyll a, phosphate, silicate, and heavy metals (Cd, Cr6+, Cu, Hg, Zn and Pb) of 104 monitoring stations in 19 coastal areas. The information was made available to the public through the EPA's website.
