In order to promoting the case management of the illegally dumped wastes, this project continues to establish the prioritized list of IDMS sites (at least 10 site inspection with cleanup suggestions), assist IDMS system enhancement, digitize forms, analyze site history statistics, evaluate waste characteristics through site investigation, modify operation procedures, and provide consultation and legal services.
In the data of the IDMS system, 49 sites are newly enlisted within the past 3 years (since 2014). This project built up a list for the said sites and inspected one by one with a result. 11 sites were selected as the prioritized ones and were determined for treatment and cost estimation. Combined with the prioritized sites from 2015-2016, 39 sites were analyzed for cleanup costs and priority. Besides, the 49 IDMS sites were cross-checked with the sites in the SGM system, ensuring that Sites IDMS 466, 497, and 527 were also shown in the SGM system.
With respect to the IDMS system enhancement, the site history management and inspection were planned and the digitized forms were proposed. The digitized forms of the IDMS system were up and running on Aug. 28, 2017. Moreover, the map information in the IDMS system was connected with those in the Forestry Bureau Aerial Survey Office. An introductory meeting for the said system enhancement was conducted on Aug. 17, 2017. Furthermore, in order to increase the efficiency of the case reporting, the evaluation employed light system with 3 levels. Incorporated with the case reporting, the local Environmental Protection Bureau will be notified once the case is reported.
With respect to the waste characteristics investigation, Sites 521 and 522 were selected with the screening principle used in 2016. Moreover, illegal waste dumping news was collected between Jan. and Nov. in 2017. Not only 15 sites were identified to be suggested enlisting, but also Site 58 (Hsinfong, Hsinchu County) was investigated with UAV video filming on July 20, 2017. In total, 3 sites (Hsinchu and Yunlin) were investigated with 37 grab samples incorporating XRF, TCLP, moisture contents, combustible contents, ash contents, volatile solid contents, odor, dioxins, XRD, and SEM/EDX. On the Site 58, wastes included furnace dust and sludge. The concentrations of the contaminants in the furnace dust were higher than the regulations, including lead, cadmium, dioxins, and furan. Zinc concentrations in the furnace dust fell between 13% and 20% with the main contents of ZnO and Fe2O4Zn, indicating the wastes were originated from carbon steel EAF rather than stainless steel EAF. As for Sites 521 and 522 investigation on Sept. 6 and 7, 2017, all samples processed with TCLP complied with the regulation although there smells of paper pulp and textile sludge. Based on the analytical results, these sludge were left unattended due to the incapable of converting the sludge into furnace fuel. According to the result of the investigation this year, the recycling procedures for the sludge of paper pulp and textile industries is recommended to be regulated as combustible contents, volatile solids, or energy value.
As for the consultation, 17 cases were conducted and 3 legal opinions were issued. 5 site visits and 15 meetings were attended. Besides, in order to process the cleanup faster for the Hsinfong site, Hsinchu County, Deputy Administer Chang advised to examine how to use the emergency funds in the consultative meeting on July 12, 2017. Based on the operation procedure of handling illegal dumping sites and work assignments, the determination conditions were added in the the need for an emergency assessment and thus emergency response can be determined by BEI(Bureau of Environmental Inspection) to whether or not fund local Environmental Protection Bureaus. The local Environmental Protection Bureaus can use the funds to carry out the emergency response.
Based on the suggestions and consultation from local Environmental Protection Bureaus, the following is recommended for 2018, involving the Article 71 of the Waste Disposal Act: (1) in order to strengthen the obligation of the land stakeholders to better manage lands, reduce the major mistakes to minor mistakes based on the example of Soil and Groundwater Pollution Remediation Act; (2) provide law enforcement to regulate the obligation of the land management of land owner.; (3) put into regulations for probation such as land transfer, land registration, etc. based on the example of Soil and Groundwater Pollution Remediation Act; (4) all pollution responsible parties have to pay back for the costs including cleanup, treatment, and other related work.
