Yilan County is always proud of its focus on “environmental protection”. To effectively improve the water quality in the drainage basin, it has, in cooperation with the policy given by the Environmental Protection Administration, been promoting the river pollution prevention and control work in recent years. However, with the industrial and commercial development and economic growth after Hsuehshan Tunnel is open to traffic, many environmental pollution problems have been caused, and moreover, Yilan County is cautious and conscientious to various rising environmental protection issues, and excepts to consider the development of environmental protection and economy, which needs to be emphasized and solved.
In Yilan County, there are 7 important rivers and brooks, namely, Dezikou Brook, Lanyang Brook, Dongshan River, Xincheng Brook, Su’ao Brook, Nan’ao Brook, and Heping Brook, with a total drainage area up to 2,143.6km2; and Yilan County administrates about 582 wastewater (sewage) causes and sewage systems. To effectively grasp and improve the water quality of each drainage basin, through the methods of “regulation under audit” and “improvement under guidance”, Yilan County has actively taken the pollution prevention and control measures and stopped illegal emissions, so as to reduce the water quality deterioration conditions of each drainage basin and further to effectively reduce the load of water environment.
Yilan County has made many efforts in the check and control of water pollution sources, river water quality monitoring, and environmental education and popularization, and also got good achievements. However, to prevent pollution deteriorating, it is still required to continuously strengthen the check and control of the pollution sources in the drainage basins, no practitioner is allowed to have legal holidays and rely on luck, to urge the public institutions to guarantee the operation and maintenance of wastewater (sewage) treatment equipment and implement the control behavior at the level of regulations.
The key point of this plan is to assist the Environmental Protection Administration to promote the water pollution source check and control as well as water quality monitoring work in the area under administration, actually grasp the current conditions of water pollution prevention and control of the pollution sources in the area under administration, and urge the responsible units to carry out the operation and maintenance of water pollution facilities through the planning check and control work, so as to achieve the goal of water improvement in each drainage basin monitoring station. The implementation results of final report from April 8, 2015 to November 30, 2015 are shown as below:
1.Assistance in the audit work of the units responsible for water pollution sources
(1)1,297 times of water pollution source auditing (including auditing (checking), sampling and sample presentation of industrial areas) have been carried out accumulatively, in which, 1,068 times belong to this plan, including 253 times: checking for industrial areas, and 211 times: assistance in water quality sampling for testing. The number of checking in 8 months of implementation of plan has reached more than 100% of the annual objective.
(2)The checking rate of responsible causes and sewage systems has reached 90.8%, and it is planned to continue the check and control work of water pollution sources, so as to reach the objective of checking rate 100%.
2.Handling of water pollution prevention and control license examination and establishment of database
(1)321 companies and 453 times have been handled for license examination, with the average number of days for license examination 4.4.
(2)Aiming at the applicant cases, 38 ones and 40 times have been examined for those needing investigation and comparison of field treatment facilities, while 284 ones and 414 times for those not needing investigation and comparison of field treatment facilities.
(3)1,911 cases on management, establishment, maintenance and renewal work of water pollution prevention and control license document database have been handled, including 1,392 on check records, 453 on license application (discharge permit, water pollution prevention measures and plan, and construction site runoff wastewater reduction plan), and 66 on sub-cases.
3.Function evaluation and guidance for proper operation of wastewater treatment facilities
Making a full use of check energy in the limited resources, conducting function evaluation of in-depth check energy, and guiding to improve the wastewater treatment facilities are creative behaviors of the year 2014, all of which have reached the goal of best inspection efficiency.
(1)As for the public and private places for improvement of wastewater treatment facilities in 2015, preliminary function evaluation to water pollution source wastewater treatment equipment, unit facility sampling, review, negotiation and other operations have been completed for four places.
(2)As for the 32 units receiving function evaluation from 2010 to 2014, tracking for improvement has been completed; due to the involvement of wastewater treatment facilities improvement work, FORMOSA-MICRO SEMI was delayed to apply for functional change on August 3, 2015, and its improvement work has been completed upon confirmation by technician on site.
(3)The guidance to 18 units’ check operations has been completed. The ones discovered to be defective after guidance have been rechecked after the given period of improvement, and 18 ones have been rechecked, in which 2 have not completed the improvement work, and the recheck results will be subsequently provided with Environmental Protection Administration to facilitate the related follow-up disposal.
4.Assistance in automatic monitoring of water quality and flow and operation of camera monitoring system
(1)Sewage Treatment Works of Service Center of Lung Te (＆Letzer) Industrial Park, Industrial Development Bureau, Ministry of Economic Affairs
As for the online abnormity during the period, it has been reported and artificially sampled according to the provisions, and the main cause of line breaking mostly lies in the failure of connection between the field monitoring facilities and the main engine. The Works has strived for funds planning to replace the main engine for the purpose of improving the online conditions.
(2)Lung Te Factory of Formosa Chemicals ＆ Fibre Corporation
On May 12, September 8 and 29, 2015, the two effluents were discovered as abnormal caused by water flow monitoring abnormality due to abnormal module transmission, and they were recovered to be normal after such discovery, and after integration, it shows that the automatic online monitoring system of Lung Te Factory is relatively stable.
5.Regular water quality monitoring work
(1)13 stations and 26 point-times for river water quality sampling and testing have been completed annually.
(2)30 point-times for water quality monitoring and sampling of 5 lakes have been completed.
