Absrtact
The content and feature within all work of this Project is directly relevant with Environmental Protection Administration (EPA) 2011 "River Pollution Remediation and Marine Pollution Prevention & Assessment Plan"; besides, they are in a large proportion. However, under joint efforts Department of Environmental Protection and all colleagues in this project have made, no matter river assessment or marine assessment, the current pro forma results are quite good. The performance of major work in this project and its implementation results are stated as follows: Scores of assistance to 2011 assessment plan of river and marine: 2011 assessment result of river pollution remediation should be able to assist in striving for score to 44.91 points in attaining assessment, in which it achieves target rate of more than 100.0%; and 2011 test results of the marine pollution prevention and control should be able to assist in striving for score to 38.7 points in attaining assessment, in which it achieves approximately 92.1%. License registration and filing management business: during planning, various applications permitted to receive were 374, among of which, 267 cases have been reviewed and approved with issuance rate 71.4%; a majority of applications permitted were coming from other industry and printed circuit boards manufacturing industry; a majority of cases pertaining to water withstand was coming from 94 cases in Nankang River; besides, another statistical review in single approval rate was 27.3%, which increased about 3.3% compared to that in 2010; as for total days counting from applications to licensing was up to 36.4 days, which reduces by 2.8 days compared to 39.2 days in 2010. Among 200 companies in execution of licensing, there were up to 87 (43.5%) of them occurring unmatched situation, which mostly are discrepancies between wastewater treatment processes at site and registered license (41%), or excessive processing units (slot body) or excessive return pipes between units...etc., in which there were 57 of them applying changes, which the improvement rate was about 65.5%. For periodical review of testing report and audit work, regardless of January, 2011 or July, 2011, the approval rate in business registry and review of this Project were both reaching 100%. Strengthening degrees of inspection and control for water pollution source: for monitoring tasks and tests in given industrial area or park storm drainages, a total of 62 sites with 744 points were under executed, which Youth Industrial District had the lowest pass rate as 70.8%; although Guanyin Industrial Zone had pass rate of 95.1%, its RD04, RD09 and RD12, RD13 had failures in heavy metal tests, which attention and awareness should be required; Kameyama and Dayuan Industrial Park, under a situation of strengthening degrees of self-implementation and self-management, its annual pass rate has improved, which were 95.5% and 94.8% respectively; while pass rate of industrial area storm drainage monitoring over the past 3 years, that of second to fourth quarter of this year were 96.0% or full year as 95.1%, which performed better compared with that of 93.1% in 2010; hence, the overall pass rate for 2011 storm drainage outfall rose slightly. The functional evaluation audit results from assigned business show that the site process of 18 companies in assessment and licensing are inconsistent with the permitted ones, and currently there have been 15 companies submitted requests of change in accordance with the provisions (7 of them were licensed, 3 of them acquired consent in change and 5 of them were in correction), in which the improvement rate was 83.3%; besides, during evaluation, there were six companies punished with penalty, among of which, Taiwan Petroleum Corporation had the highest amount of fine as NT$180,000; in addition, there were a total of 177 recommendations for improvement submitted, and after the consultation meeting held, total amount of improvement in assessment was estimated to about NT$5,890 million; and 172 improvements have been made after follow-up, which the improvement rate was 97%; as for improvement of effectiveness of treatment facilities, there were nine of them improved treatment efficiency. For tracking, inspection and control process of removing pig farmers in water area for compensation, 24 of them have stopped or changed purpose of land instead. For Inspection results of 200 communities, there were 14 of them supposed to be applicants for license but without doing this (7.0%), 39 of them were audited ones but not powered on (19.5%), 24 (12.0%) of them and 16(8.0%) of them had unmatched situations of processing units and pipelines mark respectively; and on the date of inspection, 16 of them as not powered on have been confirmed by Environmental Protection Agency which not subject to Water Pollution Control Act and conducted withdrawn process; another 12 of them without operation under management committee had its list to Department of Environmental Protection to refer to Construction and Management Unit for guidance; besides, on-site testing of exposure to the aeration tank DO value and added and contact of disinfection pool chlorine tablets on 20 communities, there were 10 communities with value of DO<2mg/L, and two of them had DO values <3mg/L; generally, DO value of this unit should be at least maintained at 3~4mg/L or above; hence, the value of operation is lower on the communities stated above. On the aspect of using drugs in disinfection tank, there were four of them pouring agents into directly; due to poor results of contact, we proposed them to use chlorine tablet buckets instead for disinfection achievement. For assistance of checking subjects should clean septic tanks and sewage objects at regular basis which meet with notice within jurisdiction, through first phase of screening process on county governmental agencies and schools who have not taken over sewers of this county (inclusive of military units), there were a total of 671, which estimates production of fertilizer is about to be 14 to 51 tons/day. In response to water pollution incident emergency: in order to immediately and effectively integrate various resources from all levels of divisions, industry groups and social organizations and acquire pollution treatment equipment and professionals to assist with 2011 water and marine oil pollution response exercise with safe, timely and effective coordination of response operations, a total of 375 people had participation in mobilization, and contingency equipments including: 7 boats in trips, 8 solid-filled booms, 9 vehicles, 1 helicopter, two groups of skimmer and oil sink each, 15 protective clothes and oil absorbent pad (vol. bar, chip)...etc.; for three seasons of ocean basin monitoring on Lauchieh River and Nankang River, it shows that most of them meet water quality of Class B Standard; part of the dissolved oxygen was slightly lower than sea water quality Class B standard, and biochemical oxygen demand> 3 and heavy metal Cu> 0.03, zinc>0.5 (Nankang River outfall), phenols>0.01, oil>2, which is slightly higher than sea water quality Class B standard. Water environment patrol business: water patrol team within jurisdiction of this county in 2011 has added two teams which up to 39 teams of size at 1,864 people total; total adoption length of river is up to 148.0 km, which has reached to 49.3% of overall one; for performance of water patrol team appraisal results, the current top three for the first group are new sky water patrol team of Yangmei City(1,768 points), water environment patrol team of this area in the same city (1,505 points), water patrol team of Yangmei Li, Yangmei City(1,451 points); the top three in the second group are Wushulin village, Longtan Township water patrol team (329 points), Dayuan Village, Dayuan Township water patrol team(183 points), and Guanyin Township Taku River Ecological conservation Association patrol team (151.5 points); other counseling services of listed water patrol team ECO-Life system registry inspection and results of activities including 302 times of river cleaning process, 180 training sessions, 175 points of reporting on dirty, 5,387 press releases, 2,348 times of inspection and 1,439 times of clean-up process; besides, 175 points of assisting volunteers to inform and deal with dirty sites on the banks of the river, and a total of 21 cases were ones with unknown water routes or underground pipe or water pollution, which total amount of NT$ 860,000 was fined; for assistance to activities related to river clean-up, 46 communication activities or educational training sessions were with a total of 3,677 participants. Operation and maintenance in ecological area: this Project assists in partial area of flow rate or operating conditions adjustment, at this stage, the cut rate of water quality, if reviewing from BOD and SS, the water quality in the work areas of bridge beneath river and Chungzheng bridge work areas was with positive result of improvement slightly; the handling effectiveness of Nankang river bridge work area drops because of large degree of variation behind inflow concentration which causes a large body of water discharging into; as for oxidation by contacting among gravels unit check process, regardless of amount of pollution reduction or processing efficiency, all have been improved.
