This project contains six parts, namely improving the functions of the Waste Dumping Management System (WDMS) and the guidelines, assisting local organizations in establishing monitoring tools for waste incineration plants and landfill sites, investigating electronic waste disposal methods, piloting air quality monitoring at potential pollution sites, assisting in managing and tracking illegal dumping cases, and carrying out system maintenance and providing administrative support.
For the WDMS, a total of six functions were improved this year. The improvements included establishing case classification labels, adding a map of waste disposal sites, creating a function for concerned waste dumping management, adjusting the worksheet fields of site survey, improving hotspot management, and establishing functions for website accessibility to enhance the management of illegal waste dumping cases, increase data applicability, and improve user-friendliness. To review the principles of tracking and delisting of illegal waste dumping cases, this project expanded the listing scope, simplified delisting principles, and added new requirements for case information disclosure. For reviewing local government inspection and notification procedures for illegal waste dumping sites, this project reduced the inspection frequency on listed sites and high-potential waste disposal sites to once every three months. Technological inspections were conducted to replace on-site human inspections.
Regarding assisting local governments in establishing monitoring tools for waste incineration plants and landfill sites, this project organized a total of 24 incineration plant visits and four landfill site visits to collect information on the status of facility and vehicle movement. This information will serve as a policy reference for the EPA to subsequently install monitoring systems using license plate recognition technology. The technology is expected to be compiled with the waste weight measured by scales in the plants to improve administrative efficiency. For investigating waste PCBs treatment, this project completed statistical data collection and 10 site visits. Domestic waste PCBs mostly underwent physical treatment and produced copper powder and glass fiber powder. Reuse organizations refined precious metals, while the options for disposing of derived waste were limited. This project suggested enterprises cooperate with the resource recycling industry to diversify recycling products and increase sales routes to promote a circular economy and improve the purity of copper used in manufacturing processes.
Regarding air quality monitoring at potential pollution sites, this project monitored one inorganic waste disposal site (WDMS Case No. 934) and took samples on July 30 and September 6. Additional TSP monitoring sites were established on the upwind and downwind sides of the site on September 6. The results indicated that the TPS values were slightly higher on the downwind side. Air at one organic waste disposal site (WDMS Case No. 582) was sampled for air contamination risk assessment. On September 24, three sets of waste samples and 10 sets of air samples were collected. The primary pollutants were C8–C13 alkanes and propanol. In addition, this project used the simulation software ALOHA to correct and obtain the area of air pollution dispersion.
For tracking dumping cases, this project established a scoring system for case reporting and regularly counseled Departments of Environmental Protection on data filling. In addition, this project compiled the inspection results and case progress of listed cases to assist in the listed case inspection, providing the EPA with control results as a reference.
