1.1 Environmental Assessment Surveys
JEMAI is conducting environmental assessment surveys
at different areas around the country on the air, water, noise, vibration, and
biological aspects on behalf of the national government, local public bodies,
related organizations, companies, etc.
a-1) Summary of Environmental Assessment Surveys Conducted in FY1997

1.3 Environmental Assessment Survey for Prevention
of Pollution Accompanying Construction of Factories
Starting from FY1965, the Ministry of International Trade
and Industry has been conducting comprehensive advance surveys on industrial pollution
in different parts of the country. Along with the amendments to the Factory Relocation
Law in October 1973, it also began conducting surveys for control of pollution
accompanying relocation of factories under the law.
JEMAI has been conducting environmental assessment surveys of the air, water,
and biological aspects of numerous areas and waters around the country as shown
by the figure and the table.

1.4 Environmental Assessment Surveys Overseas
Environmental Assessment Surveys in Singapore (FY1980
to 1985)
JEMAI conducted the following environmental assessment surveys relating to the construction of a coal fired power station and integrated steelmaking plant in the Republic of Singapore.
(1) Water
JEMAI surveyed the currents, water quality, water temperature, and other conditions
in the waters surrounding the two regions of Seraya and Tekong where a coal fired
power station and an integrated steelmaking plant were scheduled to be constructed
and projected the environmental impact after construction of the facilities using
the data obtained and data on sources of generation separately collected.
(2) Air
JEMAI conducting long-term monitoring of the concentration of pollutants (SO2)
and weather factors in the Singapore region and projected the concentration of
pollutants after construction of the plants using the data obtained and data on
sources of generation collected separately.
(3) Dust
JEMAI measured the particulate matter and weather factors in the Singapore region
throughout the year and conducted a phase IV short-term field survey concentrating
on measuring the particulate matter using a variety of measuring equipment. JEMAI
analyzed the data obtained and estimated the rate of contribution of the sources
of generation of the particulate matter using models of sources of generation
and receptor models.
Surveys of Plans for Environmental Management Relating
to Air Pollution in Samut Prakon Industrial Region of the Royal Kingdom of Thailand
(FY1987 to FY1990)
JEMAI conducted a survey of the air on site (SO2, NO2, SPM, and TSP), evaluated
the current state by simulation of the concentration of the air pollutants, studied
specific improvements in the sources of emission and estimated their costs, analyzed
the economic impact, and made recommendations on the legal system and administrative
mechanisms for the formulation of plans for management of the environment in the
Samut Prakon industrial region of the Royal Kingdom of Thailand.
