From this research, we realized the difference between ROT and BOT, for example, ROT would be easier to execute the EIA contents and conclusions. Its confidentialness in monitoring result was also higher than BOT cases. For the EIA approval kinetics, 26 approval specifications and the key items for 3 levels approval system were also offered. The policy, EIA, EIA assessment system, EIA contents development, approval system, key points for examining, following, monitoring and the results for executing effects for the surrounding facilities were researched and analyzed to offer the suggestions for practical application between Developer and Administration for the reference of executing and research.
