1. Environmental review and audit
In order to maintain the sustainable environment of the park, CTSP Bureau grasps the impact of investment behavior on the whole park by implementing total amount control and license review, so as to meet the contents of environmental impact assessment documents, review conclusions and commitments, and then conducts on-site inspection and tracking, further requiring park manufacturers to do their own management work and jointly safeguard the environmental quality of the park.
Central Taiwan Science Park is a park that implements total amount control. Enterprises that want to enter the park must put forward estimates of the total amount of individual pollution at the investment application stage. If the total amount of approved distribution needs to be increased after the official entry, they should apply for change again. The bureau will handle the approval according to the total amount of approved distribution in the park, and report it to the local competent authorities. There were 108 cases of total amount of pollution application and change in 2022-2023, and 104 cases passed.
In order to facilitate the application of environmental protection permits by park manufacturers, the single window mechanism is adopted in the park. Since 2003, the Bureau has successively applied to the Ministry of the Environment to entrust the examination of permits in various parks, so that the manufacturers stationed in the park can quickly obtain various environmental protection permit documents required for production. From 2022 to 2023, a total of 338 applications for environmental protection documents were accepted, and 319 cases were passed (including the application in 2021, which was passed in 2022 or 2023). The cases that failed were returned to the manufacturer for correction or the cases were still in the application process.
In 2022-2023, CTSP Bureau conducted a total of 465 licensing audits to find out whether the business units really fulfilled the licensing contents. If this bureau finds that the business units do not conform to the licensing contents, this bureau will immediately send a letter asking the business units to make improvements and submit relevant application documents to handle the licensing changes or changes, and also carry out the auditing of recycling institutions. The staff of this bureau and experts and scholars in related fields will assist in the auditing operation to ensure that the recycling institutions outside the park properly handle the industrial wastes in the park and prevent the outside people from recognizing them as polluting the environment.
At night or on holidays, the Bureau conducts sampling and testing of flue gas from the factory owners in the park, and monitors whether the exhaust gas discharged by the factory owners in the park complies with laws and regulations through qualified testing institutions certified by the Ministry of the Environment. The test results from 2022 to 2023 were in compliance with relevant regulations.
The bureau sets up a toll-free environmental complaint hotline 0800-777795 to provide 24-hour service, and conducts on-site inspections and handling operations. In 2022-2023, it accepted 13 complaints from the public, including 7 complaints about air pollution, 4 complaints about noise, 1 complaint about water pollution and 1 complaint about waste. The bureau immediately handled the complaints after receiving them. All the complaints in 2022-2023 have been closed.
2. Centralized sewage treatment
All CTSP parks have established a perfect rainwater and sewage diversion sewer system, and the acceptance rate of industrial sewage in the park reaches 100%. The wastewater is properly treated by the sewage treatment plant and discharged only after it meets the national discharge water and environmental impact assessment standards. The rainwater sewer system not only collects rainwater in public areas, but also manufacturers must design rainwater collection pipelines when building factories, and set rainwater discharge ports to be incorporated into the rainwater sewer system, which will be discharged into the flood detention basin in the park and then merged into the receiving water body. The Bureau also regularly arranges sampling inspection plans for sewage and sewer systems in various parks to understand the system conditions and ensure the normal water quality.
The sewage treatment plants in the park are all three-stage treatment systems, adopting standard biological treatment units of activated sludge (AO biological nitrogen removal system and contact aeration method adopted by Taichung and Houli sewage plants), and adding chemical coagulation and physical filtration treatment units in subsequent units to improve the treated water quality and reduce the impact on the bearing water body.
The operators of Zhongxing Park are mainly research and experimental industries, and no process wastewater is generated. The laboratory wastewater from the manufacturers in the park is cleared and treated by qualified manufacturers, and the domestic sewage is brought into the sewage sewer of the park and transported to Zhongzheng Road Sewage Treatment Plant for proper treatment and then discharged.
3. Environmental quality monitoring
In order to effectively prevent pollution discharge and minimize the impact of park operation on the environment, CTSP Bureau conducts environmental monitoring every year according to the environmental monitoring plan contained in the environmental assessment document, including air quality, noise and vibration, water quality of discharge water, surface water quality, groundwater quality, sediment, soil, ecology, traffic volume and cultural assets, etc., with a total of 4,338 points/times from 2022 to 2023. The environmental monitoring results of our bureau are all open and transparent, and published on the CTSP Park Environmental Information Integration Network for public browsing.
In order to further understand the current situation of environmental factors other than environmental assessment documents, the bureau added some supplementary monitoring items from 2022 to 2023, including air quality, noise and vibration, water quality of discharged water, surface water quality and groundwater quality, and conducted a total of 1,169 additional environmental monitoring points/times from 2022 to 2023.
In addition, in order to improve the reliability of monitoring data, the Bureau also carried out parallel monitoring in 2022-202 3, including general air quality, acid and alkali gas, odor, flue detection (including night detection), water quality of civilian wells and other items, and carried out synchronous testing from time to time to ensure the quality of monitoring data. At the same time, in order to understand the night emission situation of manufacturers, it conducted six flue spot night checks in 2022-2023 together with the Environmental Protection Supervision Subcommittee (local leader). It is hoped that the impact of park operation on the environment can be truly understood through irregular testing.
