The major categories of assessment are as follows:

– Natural environment (5): climate, topography and geology, animals and plants, oceanic
environment, navigability and hydrology;
– Living environment (11): use of land, atmosphere, water quality, soil, waste, noise and
vibration, bad odors, radio wave disturbances, sunlight disturbances, leisure and
scenery, hygiene and public health
– Social and economic environment (7): population, housing, industry, public facilities,
education, traffic, cultural goods, etc.

There also exists a focused assessment system, which concentrates on special categories of the company with important environmental impacts considering their special qualifications and specifications.
The assessment document filled out by the business itself is submitted to the competent agency. From there, the document is conveyed to the Ministry of Environment (or local environmental agency) for review. The Ministry or local agency will then review the assessment document and send the result back to the competent agency for approval with comment after making necessary changes or supplementation, if necessary.
For the effectiveness of this assessment system, a proper execution of this system is required, and the business shall therefore comply with the results of and the regulations set in the assessment. Therefore, obligation to conduct further research about impact on the environment as well as appoint a person in charge to manage and comply with the regulations of the assessment etc. have to be fulfilled. Furthermore, a penalty will be levied when violating the amount of concentration of pollutants that are discharged.
In addition, the competent agency in charge of approval has to undertake the necessary measures to guarantee the compliance with the results of the assessment and if necessary also have the authority to order the halt of the construction through on-spot inspection. Local environment agencies can request to the business or the approving agency to undertake necessary measures such as stopping ongoing construction processes if it finds it necessary.
