Abstract
This project aims to assist Yilan County Government Environmental Protection Bureau in promoting the water pollution source inspection, control work, and water quality monitoring work, in order to determine the current status of water pollution prevention and treatment in Yilan County. The results can be used to urge the units under the jurisdiction of Yilan County Government to maintain the operation of water pollution prevention and treatment measures through the planned inspection and control work, thus achieving the objective of improving the water quality in various river basins. According to the statistics in the final report, from April 7, 2014 to November 30, 2014, the implementation achievements are as follows:
1. To assist in the inspection of water pollution sources.
(1) Among the 611-time inspections on water pollution sources (including industrial area audit inspection (check), sampling and sample presentation), there were 514-time inspections carried out under this project, including 140 enterprises in the industrial parks, and 182 enterprises submitted the water samples for testing. During the 8 months’ implementation of the plan, 97% of the annual objective had been reached. In addition, according to the statistics, by December 8, 2014, 201 enterprises submitted the water samples, with annual objective reaching above 100%.
(2) Among the enterprises being monitored for water pollution sources, 123 enterprises in the industrial parks (excluding petrochemical special zone), were inspected, accounting for the most (22.2%), followed by husbandry farms (99 enterprises), construction sites (94 enterprises), earthwork excavation, processing and stacking (51 enterprises), sewer (56 enterprises), food production (25 enterprises) and wafer and semiconductor manufacturing (24 enterprises).
(3) There are 306 enterprises being monitored as the water pollution source hot areas along Dezikou River, Lanyang River and Donshan River in Yilan County, as announced by the Environmental Protection Administration (EPA). According to the statistics, by the end of November of 2014,180 enterprises had been inspected, with an accumulative inspection number of 354, and hot area inspection and control rate up to 59% (180/306). In addition, 47 enterprises provided effluent water samples.
(4) There were 71 events of reporting and punishment on violation of water pollution law during the implementation of water pollution source inspection, with a total penalty of 6,453,000 NTD, in which there were 19 events of punishment on violation of relevant provisions of water pollution law in the basins of Dezikou River and Lanyang River, respectively accounting for 26.8%.
(5) During the inspection, 5 unclear pipelines were seized, and the owners had been required to remove the pipelines for improving, and this would be tracked in the following.
(6) During the inspection, 14 pig farms were guided to set up 243 simple defecation frames. In addition, according to the statistics, by December 8, 2014, 19 pig farms had set up 309 simple defecation frames, with an annual objective above 100%.
2. Audit for handling of water pollution prevention and treatment license and construction of database
(1) 189 enterprises handled the license, with 307 audit events, and it took 4.0 days to carry out the audit on average.
(2) Among the application cases, 26 enterprises needed to receive on-site inspection and facility comparison, with 28 audit events, and 163 enterprises not needing to receive the audit of on-site treatment facility survey and facility comparison, with 279 audit events.
(3) There were 887 implementation events of managing, constructing, maintenance and updating the water pollution prevention and treatment license, including 656 inspection records, 160 license application events (discharge permit, water pollution prevention and treatment measures and plan, construction site runoff waste water reduction plan), and in addition, 71 treatment events were filed.
3. River water quality, branch discharge water quality and quantity investigation and lake monitoring
(1) In this year, water quality sampling test has been completed in 39 points in 13 stations.
(2) 30 points completed the water quality monitoring sampling for 5 major lakes.
(3) There were 10 points implementing Dezikou River branch discharge water quality and quantity investigation, totally 20 point-time inspections.
4. Functional evaluation and tutoring for proper operation of waste water treatment facilities
(1) For the public and private places with improvement of waste water treatment facilities in 2014, the initial functional evaluations on water pollution source waste water treatment equipment, unit facility sampling, review and negotiation have been completed in 5 enterprises.
(2) 11 enterprises implemented functional evaluation in 2012 and 2013, and the improvement tracking had been completed for all of them in the middle stage. Luodong Township Farmers’ Association Food Processing Plant delayed to April 30,2014 to declare the functional change due to the improvement of waste water treatment facilities, and upon the on-site survey by the technicians, it has been completed the improvement.
(3) Inspection has been completed for 39 tutoring enterprises, those absent upon the on-site survey by the tutoring group have been arranged for review after improvement in a limited period, the review of 39 enterprises has been completed, in which 5 enterprises have not completed the improvement, in the following, the review result will be provided to Yilan County Government Environmental Protection Bureau for relevant treatment in the following.
5. Ecological investigation in the river basin
(1) 7 monitoring stations, including the monitoring stations in 2013 and the newly added Wufengqi and Dachung Bridge monitoring stations completed 2 investigations in 14 places, and the result showed that in the downstream sampling stations, the Shannon-Weaver diversity index and average degree of demersal large invertebrates had a significant degree (reduce from upper stream to lower stream), which was more significant than the change of fish.
(2) The Hilsenhoff family index of demersal insect in Dezikou River for years showed that although there was a great change in the value of Meiching Inn, compared with other 6 sampling stations, it was still a station with good water quality; the value was changed mainly because the large invertebrates in addition to insects were included. Qijie Bridge was a sampling station with relatively poor environmental conditions, similar to Erlong River and Qijie Bridge, Shichao Bridge and Chu-an Bridge are tidal reaches, and tide would cause the frequent change of water quality environment.
6. Early investigation in the river basin
(1) The early investigation on the total control in the upstream basin of Dezikou River Qijie Bridge section was completed. According to the pollutant emission estimation result, the BOD pollution amount in this pollutant collection area was 413.37 Kg/Day, while the NH3-N pollution amount was 141.59 Kg/Day, which should be reduced by NH3-N 102.71Kg/Day to conform to the water body quality standard Class C, upon estimation, the BOD pollution amount was in the allowable pollution load, but according to the inspection declaration data, there might be an underestimation, and it is still suggested to list this item as the improvement objective, so as to reduce other pollutants synchronously.
(2) To complete the planning of water division in Dasi River.
7. Emergency response of water pollution event
(1) 218 inspections were completed for the ports under management, the inspected ports were the most in Wushi Fishing Harbor, accounting for 11.5%, followed by Nanfangao No.1 to No.3 harbor basins, respectively accounting for 11.0%.
(2) Water pollution emergency material checking, care and operation maintenance were implemented twice every month.
(3) 2014 Hualien-Yilan combined ocean, river pollution emergency response and toxic chemical disaster prevention exercise without warning was carried out together with Hualien County Government Environmental Protection Bureau, 1 preparation meeting, 1 on-site-spot survey, 2 work coordination meetings, 1 formal exercise without warning and 1 review communication meeting were held in this exercise, with 5 ships used and 130 persons participating in the exercise.
