dc.description.abstract | In Taiwan, the necessary items for environmental monitoring applicable to environmental impact assessment (EIA) lack a clear definition. The required environmental monitoring indices are divided among different EIA review meetings. The goal of this study is to take golf court development as an example for assessing the practical demand of environmental monitoring. Questionnaire approach is adopted to investigate potential improvement on environmental monitoring in EIA.
Delphi Method is selected as the method in this investigation and the questionnaire approach on the determination of environmental monitoring index is completed in three rounds. In the first stage after questionnaire being completed, a statistical paired t-test is used to verify the stability of the significance for monitoring groups and indices chosen by the participated scholars and experts. In the second stage, a criterium of larger or equal to 3.5 (the highest score is 5) and the standard derivation (SD) less than 1 serves to determine achieving consensus of the participated scholars and experts. There are 89 environmental monitoring indices resulted from the selection process.
The environmental monitoring indices selected for the construction period are thirty three in total including six for “site effluent”, nine for “receiving water body”, three for “air quality”, three for “hill slope stability”, seven for “noise”, four for “vibration”, three for “ecology”, and two for “traffic”. For the operation period after construction, fifty four environmental monitoring indices are selected as follows. They are fourteen for “wastewater treatment plant effluent”, fourteen for “water quality of receiving water body”, ten for “groundwater quality”, three for “ecology”, three for “soil”, three for “hill slope stability”, and five for “retarding basin or vista body effluent”, respectively.
In the latter stage, based on the selected 89 monitoring indices, the environmental monitoring assessment system in golf court is established through the consideration of average weighting process and monitoring cost, which could be taken as a planning and management tool for developing party and the authorities. According to the established assessment system, the most cost-effective monitoring index during the construction period is to monitor “SS” or “BOD” of “site effluent”. In contrats, during the operation period after construction, “BOD” in both “wastewater treatment plant effluent” and “receiving water body” is the most cost-effective monitoring index.
