 Inspection Team: Working Discount in Dazu District, Chongqing

I. Basic information

Yutan Lake (also known as Yutan Reservoir) is located in the upper and middle reaches of Seti River, the first-class tributary of Tuojiang River basin on the left bank of Yangtze River in Dazu District, Chongqing. It is one of the four major water supply projects in Western Chongqing. It is also the main water source project for farmland irrigation and urban water supply in the Seti River Basin of Rongchang and Dazu District, with a water supply population of more than 500,000 people in urban In order to strengthen the protection of Yutan Lake, in 2013, it was included in the category of better water quality lakes supported by the state, and has received 610 million yuan from the central government, including 468 million yuan from Dazu District.

The approval of Chongqing Municipal Peoples Government on the general plan for the ecological environment protection of Yutan Lake in Chongqing (2013-2017) (No. 74 of Yufu [2013] requires that the water quality of Yutan Lake is better than Class III from 2015. However, the monitoring data show that the water quality of Yutan Lake has not reached or surpassed Class III steadily. Since 2017, the water quality has not risen or fallen, and has generally fallen to Class IV. From January 2017 to June 2019, the number of months in which the water quality of Yutan Lake National Assessment Section could not reach Class III was 20 months, accounting for two-thirds of the total, of which four months worsened to Class V or even inferior Class V.

II. Major Issues

(1) discount on the construction of pollution control projects

According to the Overall Plan for Eco-environmental Protection of Yutan Lake in Chongqing (2013-2017) and its annual implementation plan, the Dazu City Sewage Treatment Plant should complete 30,000 tons/day expansion project by the end of October 2016, raising the treatment capacity from 30,000 tons/day to 60,000 tons/day, but the expansion project did not start until December 2016. The project was completed in November 2017, and only 15,000 tons per day of new treatment capacity was added, resulting in the long-term overload operation of the sewage treatment plant, with a daily maximum water inflow of 68,000 tons, which is about 1.5 times of the actual treatment capacity. A new industrial wastewater treatment plant for 30,000 tons per day should be built in Area A of Dazu Industrial Park by the end of December 2014. The actual capacity of the plant is only 10,000 tons per day. Fushou Village Township Sewage Treatment Plant Technical Renovation Project should be completed by the end of December 2016, but the project was completed only in February 2018, which is one year and two months behind the requirements of the scheme.

(2) Large gap in sewage treatment capacity

According to the general plan for ecological environment protection of Yutan Lake in Chongqing (2013-2017), the centralized treatment rate of municipal domestic sewage in Yutan Lake basin should reach 85% in 2017, which is only 66.2% in practice, far from meeting the target. Chongqing Municipal Management Committees Notice on the Examination and Inspection of Urban Management in 2018 requires that the sewage treatment rate in Dazu District should reach 92% in 2018, and only 77.56% in practice, which is far from the target. According to the information provided by Dazu District, a total of 102 outlets of sewage in and out of rivers were investigated in this area in 2019, most of which were direct outlets of domestic sewage.

(3) Illegal encroachment on the first-class protected areas of drinking water sources

Yutan Lake is a centralized source of drinking water for cities and towns approved by Chongqing Municipal Peoples Government. The Law of the Peoples Republic of China on the Prevention and Control of Water Pollution clearly stipulates that it is forbidden to build, rebuild or expand construction projects unrelated to water supply facilities and protection of water sources within the first-level protection zone of drinking water sources. However, inspectors found that in December 2016, local residents illegally built new houses in the first-class drinking water source protection zone of Yutan Lake, occupying a total area of 847.17 square meters, which posed risks to the water quality of the drinking water source of Yutan Lake.

(4) Imperfect implementation of regional approval restrictions

Chongqing Municipal Bureau of Ecology and Environment (Chongqing Municipal Bureau of Ecology and Environment) clearly requested that the approval of the Yutan Reservoir watershed should be suspended except for the projects of peoples livelihood, industrial energy conservation and emission reduction, and environmental protection. Emission construction projects. However, the inspectors found that the ecological environment department of Dazu District did not strictly implement the requirements of regional approval. During the process of approving construction projects, the environmental impact assessment reports of 49 construction projects examined and approved during the period did not evaluate or evaluate whether the project discharged total phosphorus water pollutants, leading to the approval of some phosphorus-related projects. Being released. From 2017 to 2018, Dazu District carried out 168 tests on effluent from 19 township sewage treatment plants in Yutan Reservoir Basin, of which 46 cases exceeded the total phosphorus standard, accounting for 27.4%.

3. Cause analysis

The good lake protection of Yutan Lake is a major ecological environment protection project invested by the central government. The government of Dazu District pays insufficient attention to its importance and urgency. The implementation of the General Plan for the Ecological Environment Protection of Yutan Lake in Chongqing (2013-2017) is not in place. The scale of the project construction is reduced and the time limit for the project construction is delayed. Pollution control efficiency of state investment projects has been greatly reduced.

The relevant functional departments (units) do not act. After the water resources department of Dazu District and the relevant territorial town government learned about the problem of illegal construction of houses in the first-level protection zone of drinking water source of Yutan Lake, they neither took effective measures to stop it in time nor reported the illegal construction acts in time according to the regulations, which led to the completion of illegal construction projects. The Department of ecological environment in Dazu District has not strictly checked and approved new projects, and some of the phosphorus-related projects that should have been restricted have passed the examination and approval.

In response to the above problems, the inspection team will further verify the relevant situation and require local authorities to investigate and rectify according to law and discipline.
