assessment procedure. The origins of environmental
effect appraisal can be traced back to the National
Environmental Policy Act of 1969 in the United
States. This concept arose from realizing numerous
publicly supported plans overlooked potential
environmental repercussions during planning and
implementation, inevitably leading to serious
environmental issues. It was initiated because several
government-funded projects failed to consider their
environmental impacts during development and
execution, resulting in substantial environmental
issues. Historically, analysis of cost, benefit, and
environmental protection was the primary focus, but
it was inadequate for safeguarding the environment
within the country. Consequently, public awareness
regarding the environment grew, leading to a
movement that eventually enabled the enforcement of
EIA as a mandatory law starting in January 1970.
EIA became a global foundation for similar
legislation worldwide in the 1970s and 1980s for
developed countries. Countries in Asia that were
developing, such as Indonesia, Taiwan, the
Philippines, Singapore, and Hong Kong, embraced
the concept of EIA within their policies by 1990.
Subsequently, African and Latin American countries
adopted this approach, [9].
In Thailand, the formal beginning of
environmental legislation occurred with the passing
of the National Environmental Quality Advancement
and Preservation Act 1975. This Act established the
National Environmental Board, tasked with specific
responsibilities, including developing policies and
recommendations to boost and safeguard
environmental quality. Another crucial role involved
assessing initiatives that could negatively impact the
natural world. Subsequently, the Act underwent
revisions in 1978, resulting in its second version.
Specifically, regarding the authority and duties of the
National Environmental Commission, these changes
aimed to address vague areas and weaknesses in the
original Act. However, despite these attempts, some
key details remained undefined, leading to challenges
in implementation. Then, the government was
required to tackle these issues; further modifications
were made in 1975 and 1981 to provide more explicit
and inclusive powers and accountabilities to the
National Environmental Board.
Furthermore, in 1981, a new policy was
introduced to evaluate the environmental effects of
specific project categories and scales. Under the
authority of the Ministry of Science, Advancement,
and the Surroundings, this policy took impact on
September 27, 1981. It centered on analyses of
environmental assets and the significance that diverse
projects or deeds could have. In 2002, the
government changed how it handles things. The
Ministry of Science, Technology, and Environment is
now responsible for the National Environmental
Quality Promotion and Conservation Act 1992
(B.E.2535). In April 2018, a revised version of the
National Environmental Quality Promotion and
Conservation Act (Version 2) was enacted, with
multiple subordinate laws issued to establish clear
frameworks and impose penalties for non-
compliance. These legal measures were intended to
compel businesses to consider environmental impacts
more seriously, ensure the creation of accepted
standards, and foster confidence from all
stakeholders in environmental quality and natural
resource conservation. The country's sustainable
development was balanced with maintaining
environmental quality and natural resources, [10].
The following are 4 benefits of EIA that need
attention and can be seen from various aspects, [11]:
1) The benefits of EIA for the government
are more related to policy formation. The government
has higher authority than any party. Therefore, the
use of an EIA is to help prevent more severe
environmental damage and pollution. In addition, the
EIA project benefits the government; this project can
be used as a form of government responsibility in
preserving and protecting the environment. The
ultimate goal remains the same: avoiding conflicts or
disasters that will endanger the community.
2) The owner of capital here can be
exemplified as a bank that holds power over the
fortune of entrepreneurs. The benefit of having an
EIA for capital owners is that it is easy to provide
loan capital for a development or project. That is if a
party borrows money from a bank to build a project
and the EIA of the project is good and of good
quality. So, banks must provide loans for this
development.
3) The next benefit of EIA is for project
owners or companies, where EIA is essential for a
company. The EIA will benefit the project owner
because it will guarantee that project development
will continue without violating the applicable laws
and regulations. An example is when a housing
complex is constructed; the developer must have a
good EIA. That way, the government and capital
owners will give permission easily. In addition, the
