This project contains six aspects, including refining the functions of the Waste Dumping Management System (WDMS), investigating the environmental characteristics of dumping sites and examining the rules of dumping hotspots, investigating the treatment and disposal of waste wood, applying remote sensing technology to improve the monitoring capabilities of dumping sites, evaluating and tracking illegal dumping cases, and providing administrative support and ensuring the security and stability of the information system.
In 2022, five system functions were refined, including introducing satellite image variation information of dumped waste, modifying case listing and delisting principles and site inspection functions, adjusting site investigation data fields, adjusting the integrated inquiry and public notification functions, and enhancing case investigation and processing functions. Users from the Department of Environmental Protection (EPD) can use the WDMS to query and confirm variation information, making the system more user-friendly and convenient to fill in data. The system can also smoothly connect to the updated management regulations announced this year.
Regarding the analysis of the environmental characteristics of dumping sites, this project investigated the correlation between WDMS site locations and environmental characteristics, such as roads, population density, industrial areas, and environmental facilities. According to the results of the correlation analysis, the correlation between urban roads, rural roads, and site locations was relatively high, and 95% sites were located in rural-urban areas with a population density of fewer than 5,700 people/km2. Based on the results of the correlation analysis, this project proposed strategies for designating sites and hot areas for the Environmental Protection Administration to conduct future inspections and management. This project proposed to designate alert zones of one kilometer on both sides of the road near the sites and hotspots. Idle factories, fish farms, valleys, rivers, agricultural land, and vacant land in the alert zones could be frequently inspected.
To investigate the treatment and disposal of waste wood, this project conducted statistics on the current status of the industry and the reported data. The treatment was investigated, and waste wood manufacturers or suppliers were visited to identify the sources of waste wood produced during the manufacturing process. This project also visited waste wood treatment or recycling organizations to investigate the problems and needs of the industry. Ten on-site visits were organized, and the information on the current status and costs of each treatment organization was compiled.
Regarding applying remote sensing technology to enhance the capacity of monitoring dumping sites, this project used unmanned aerial vehicles (UAVs) to conduct site monitoring and photography for six times. Tasks included (1) inspecting and comparing WDMS No. 382 site and No. 138 site before and after image changes; (2) implementing aerial photography of Erh-Jen River dumping site; (3) quantitative monitoring of a cleanup site in Kaohsiung. In addition, based on the results of the trial UAV site monitoring, this project proposed the UAV inspection and monitoring guidelines to serve as a reference for the EPD.
As for tracking dumping cases this year, this project completed the following tasks: establishing a scoring system for case data filing, regularly counseling the EPD to fill out the report, compiling the inspection situation and case progress of listed cases, and assisting in reviewing listed cases to serve as a reference for the EPD as their control results of the current phase.
