The project is funded by a total of 5.27 million yuan (6,635 yuan) from the EPD of the Executive Yuan and a total of 2.15 million yuan (5,245 yuan) from the fund-raising subsidy, totaling NT $ 7,430,880, starting from the compliance date (January 25, 106) until November 2006 The overall progress of the implementation of the project on the 30th reached 100%, the progress of the work done by each project, the highlights are summarized as follows:
First, the regular monitoring of groundwater monitoring wells
(I) The abundance and groundwater monitoring results of 15 field groundwater monitoring wells are all below the groundwater control standards, and only ammonia nitrogen, iron and manganese exceed the monitoring standards. There is no significant difference with the monitoring results over the years. C00007 (Conductive Anomalies), Six Wastewater Treatment Plant C00011 (Dichloroethene ＆ Dichloroethane) and Societe Generale C00004 (Low pH, Average pH4) and other issues, in addition to continuous monitoring, should also clarify its Where the problem is, such as funding constraints, if necessary, submit a proposal to the EPD for grants.
(II) Liudu Riverside Sports Park (C00032) This year Trichlorethylene was 0.0593mg / L in the second season and 0.0703mg / L in the third season was over the control standard (0.05 mg / L). Six Cliff Riverside Park 101 (C00033) The third quarter of 0.0639mg / L exceeds the regulatory standards (0.05mg / L).
(C) from the redox potential, dissolved oxygen, the concentration of trichlorethylene and groundwater measured changes in dichloroethene, data assessment, trichlorethylene does have degradation, no measurement of vinyl chloride may be due to the proximity of Keelung, Keelung by River water level affect the relationship.
(D) According to the findings of the China Electronics Corporation (EPD) on the results of the survey conducted by the EPD, chromium and groundwater Trichlorethylene in the original plating area exceeded the regulatory standards. The EPA assessed the relationship between groundwater flow according to the elevation of groundwater level and the use of chlorine-containing degreasing agents in the early electroplating degreasing process. The use of chlorine-containing organic solvents in the process of seven factories was found. It is estimated that the contamination of trichlorethylene in two groundwater monitoring wells in Liudu Riverside Park may be the impact of China's electronic groundwater pollution. Following the announcement of China Electronics's site for soil and groundwater pollution control , It is recommended that an expanded survey should be conducted to include C00032 and C00033 in the investigation and improvement and to remind CNEOC that if sampling needs of C00032 and C00033 groundwater monitoring wells are requested, they should be informed ahead of time and sent by the EPB for the future The improvement plan should be based on the analysis and assessment of changes in the concentration of trichlorethylene and rainfall, groundwater level, flow direction, season, etc., in order to grasp the trend of groundwater flow and trichlorethylene in the area as a whole.
Second, groundwater monitoring wells to maintain management
(A) to complete the monitoring well inspection and maintenance work and paint painting work, the internal function test results without any exception.
(2) Completion of the maintenance of the monitoring wells of the Beidou Motor and Taiwan Fertilizer Base Keelung (upstream wells) and the rehabilitation of the medium wellbore facilities in the PRC; 中 Zhongwu Industrial Metal Co., Ltd., Dawulun and Ruifang Industrial Zone, Ministry of Economic Affairs Center and Fuji Weaving (next to sewage facilities); Completed the exclusion of foreign bodies from Shenzhen American Elementary School, ZTE Elementary School, Beidou Automobile Co., Ltd., Liuci Technology Park Management Center and Liuzuo Riverside Sports Park in Qixian District .
(III) List of Priority Ranking for Follow-up Well Condition Assessment Suggested: Field Settlement Qiliu Riverside Sports Park 101, Baifu Park Management Station in Qilu District, Dawulun Industrial Zone, Upstream Well of Keelung in Taiwan Fertilizer Station, Six Wastewater Treatment plant; regional American deep small, five plug small.
(D) Recommended list of priority foreign matter excluded follow-up: field set for the Fuji weaving (next to the guard room), wells downstream wells, 7 plug block Six plug Riverside Park 101, 6 sewage treatment plants, gas station in Mingde ; Five for a small regional culture, build a small German.
Third, site supervision and management
(I) The sites for pollution control under the jurisdiction include the Quanyi Gas Station, the Fifth Factory of Yuanzhang Glass Co., Ltd. (formerly the Dawulun Steel Plant of Daewoo Iron ＆ Steel Co., Ltd., hereinafter referred to as Daewoo Iron ＆ Steel), and according to the Soil and Groundwater Pollution Control Law Article 5 of the 7th Measures for Strain Remedies The site is Taichung Keelung gas station and 48 inspections have been conducted. On August 18, 106, the work of Daewoo Steel and Taichung Keelung gas station was carried out in accordance with the relevant provisions of the Soil and Groundwater Pollution Remediation Law Discharge management.
(2) The 2nd meeting of "Spring Promotion Station for Soil and Groundwater Pollution Sites Improvement in Keelung" was held on October 24 in Quanyi Gas Station. The conclusion of the meeting was reviewed and approved by the members in writing. The agreement was approved in principle to improve the principles of the schedule Agreed to be postponed till October 19, 2009 and December 8, 106. The written examination and approval by the members agreed to pass the examination and the unemployed submitted the "Plan for Controlling the Site for Soil and Groundwater Pollution Control at Quanyi Gas Station - 2 times (final version) ", after the expiration of the application can not be extended.
(C) Environmental Protection Bureau at North Beilun Road gas station notice of soil and groundwater pollution site before the statement of opinion, the company statement does not affect the pollution facts are clear, industry in November 16, 106 announcement of soil and groundwater pollution control field site.
(4) Since there is no uniform standard for determining the site in each counties and cities according to Article 7 (5) of the Soil Pollution Law or the 12th announcement as the control site, at present, there is no standard set by the Central Government. Therefore, Basis for the premise, taking into account the principles of the law, such as soil pollution case, because the soil is more difficult to spread movement, can be held in the Chamber of Commerce view site actual pollution and improve the way to decide whether to give emergency measures to be taken to avoid the poor to improve the situation , Check points can be added to keep abreast of the progress to be met, but groundwater flow variability is large, the proposed direct announcement can be used as a control site to avoid the risk of proliferation, to demonstrate the Environmental Protection Agency for the promotion of soil and water business in order to enhance Pollution control aging.
(E) the area subject to S code contaminated soil site for the BOO final disposal site, the future plan can be incorporated into the S code code for contaminated soil sites to check, learn and grasp the amount of soil received for the follow-up management, In addition, the EPD's Land Foundation has planned to accept S code code of contaminated soils to include sites 8 and 9 for the announcement of the 3rd ladder business. The future may be supervised and managed in accordance with the relevant provisions. The company is located in:
Fourth, high pollution potential investigation and management
(I) Large Storage Tanks: After the completion of five large-scale storage tanks, the existing soil samples were collected and evaluated for 12 times. The results showed that the concentration of TPH in the sampling site 2 (No.1 heavy oil daily tank) was 8,320mg / kg up to the standard of 8 times (control standard is 1,000mg / kg), so it is proposed by EPB to add new projects. 7 groundwater samples are collected to clarify whether there is any groundwater pollution or not. Results of analysis Groundwater pollutants No exceeding the regulatory standards. However, due to the fact that the TPH pollution of Xiehe Power Plant soil is clear, the daily use of heavy oil tanks mainly provides generators. As the plant provides electricity for people's livelihoods in the northern part of the country, improvements in management according to the law may affect people's livelihood and After 108 years, the plant will replace natural gas with fuel to generate electricity. It is suggested that the plant should communicate with the EPD to discuss follow-up administrative measures in this case.
(B) The final disposal site of Keelung BOO: Completion of 8 tests of groundwater in abundance and dry season, analysis of data results, groundwater control heavy metals and other projects did not exceed the regulatory standards, and the regular test of nearly 3 years of data, the ammonia nitrogen, iron and Manganese has exceeded the groundwater monitoring standards, and there are traces of heavy metals arsenic, zinc, did not exceed the regulatory standards, but the conductivity showed a slightly higher chloride salt, sulfate and nitrate values occasionally low, There is not much difference between the test data and the test data, and the problem of vinyl chloride and methylene chloride is also detected. Since the site regularly monitors the absence of (semi-) volatile organic compounds, it is recommended that the EPA should allow for future funding and monitor it continuously. The site provides regular monitoring data collection, to facilitate the understanding of changes in their differences.
(III) River Sediment: The XRF sieve and the 2-point sediment extraction at the 5 o'clock position of the Great Wulixi Creek were completed. The evaluation of the RAC wind was of no low risk. Only the lead was at risk, and the sediment heavy metal exceeded the sediment QUALITY INDICATORS LIMITATIONS Upstream of Dawulunxi area (near Xingye Metals Company and Dawulun Industrial Zone), there is no factory to initially eliminate the waste water pollution and there is no risk or low risk for sequence extraction. The non-public recreational areas, No direct contact with the possibility of sediment to reduce the risk of health risks, but whether for the factory exhaust emissions caused by dust or erosion and other causes of pollution, remains to be clarified; another Ma Lingkeng 10 points sediment analysis, the heavy metal concentrations and the medium The downstream did not show a positive relationship, and located in the downstream sampling point near the sun industry, and then no other upstream plant, no other possible sources of pollution after the survey found that river sediment of heavy metals such as cadmium, mercury and zinc over sediment quality Limit standard preliminary ruled out factory waste water pollution caused. Because the main purpose of monitoring sediment by the Environmental Protection Bureau is to establish background information, it is suggested that the relevant testing data be provided to the river management authority for reference if necessary. Such measures shall be handled by the relevant authorities in accordance with the classified management and usage restrictions of the sediment quality indicators.
Fifth, underground storage tank inspection and management
(A) To complete 16 on-site written inspection operations and to advise against continuing inspections of other non-verified gas stations to keep track of the operation of all underground storage tank operators so as to provide guidance on the strengthening of internal material control and the actual reporting of information.
(B) to complete the 11 test leak test tube function test and oil and gas testing (originally planned for 7 stations, due to planning waste wells and site validation project does not require the implementation of the new 4 times the leak test Tube function test and the change of oil and gas from the Bureau of Environmental Protection of Keelung to the Department of Environmental Science and Technology for approval), 5-point soil gas was collected for GC / FID analysis. No BTEX, MTBE and n-decane were detected. Only methane .
(C) Refer to the EPD Soil and Groundwater Investigation Program at Petrol Filling Station Soil GC Identification and Follow-up Tactics and According to the EPA's 105 Soil Gas Pollution Potential Grading Rules, Cheung Fung Street Gas Stations are classified as Grade B2 with 3 Monthly tracking 1; 碇 within the gas station classification B1 level, to be tracked once every 2 months; up to 3 consecutive anomalies, the implementation of soil and water investigations; Zhongzheng three gas stations, eight gas stations, all the way gas stations And seven national gas stations classified as C-level pollution-free danger.
Sixth, the impact of food safety risk area identification
(1) The PCDDs / Fs content in soils around the incineration plant is low (much lower than the regulatory standard), and the soil samples from 10 soil samples (106-07-S-6 and 106-07-S- 8,106-07-S-9) PCDDs / Fs are slightly related to the fly ash of the incineration plant. However, it is difficult to determine whether the number of PCDDs / Fs is statistically significant or not.
(2) There is no significant difference between the heavy metals in the perimeter of the incineration plant and the general soil quality, and they are in line with the relevant pollution control standards. So far, the fingerprints of heavy metals in soils are irrelevant to the boiler ash and the reaction ash in the incineration plant.
(C) Proposes to increase the number of tests to be ascertained with a view to clarifying the relevance of future tests if permitted.
Seven, regulatory advocacy briefings
(I) Completion of the Gas Station and Underground Storage Tanks Regulations and Advice Briefing Session 1 Soil and Groundwater Pollution Remediation Laws and Regulations 8 and 9 Regulatory Briefing Session 1 Education and Training Session for Relevant Professionals 1 Exchanges Across Counties and Cities And campus tour propaganda 3 games, a total of 414 people participated in the total.
(B) It can be learned from the questionnaire recovery through the Regulatory Announcement that the industry practitioners will give affirmations for the declaration of the declaration. In the future, in addition to continuing to regulate the real estate market, we can consider the actual needs of the industry and recommend the addition of prevention and management, practical techniques and soil assessment surveys And test data should pay attention to the key points, which can provide the operator with reference to strengthen the management side; business education and training of staff and cross-county exchanges have practical benefits for the management of the business. Recommendations follow-up sustainable development according to the actual needs of the Environmental Protection Agency; Easy-to-understand, lively and fun way to interact with school children, they usually get good propaganda effectiveness. We suggest that they should be handled continuously to establish the concept of children's awareness and protection of soil and groundwater.
