The thirty-sixth rectification item specified in the "Rectification Plan for Implementing the Second Round of Central Ecological Environmental Protection Inspector’s Report in Jiangsu Province" has been rectified. According to the "Measures for the Rectification of Ecological Environmental Protection Inspectors in Jiangsu Province" and other documents, the completion of the rectification of this problem is now publicized as follows:
I. Rectification matters
The water quality decreased obviously in flood season. In Huai ‘an, a large amount of sewage and garbage accumulate in the upstream of drainage pumping stations and culverts, and flow into the river with rainwater in flood season, which seriously affects the water quality in the downstream of the basin. In the flood season of 2020 and 2021, the water quality of six important rivers and lakes such as Zhangfuhe, Tangxianghe and Baima Lake decreased significantly. In July 2021, the proportion of excellent water quality sections in the 11 national examination sections in the city was only 27.3%, down 9.1 percentage points year-on-year, and the water quality of four rivers, including Nanliutang River, fell to worse than Grade V..
Second, the responsible unit
Huai ‘an Municipal Party Committee and Municipal Government.
Third, the acceptance unit
The Provincial Department of Ecology and Environment takes the lead, and the Provincial Department of Housing and Urban-Rural Development, the Provincial Department of Water Resources and the Provincial Department of Agriculture and Rural Affairs cooperate.
Fourth, the goal of rectification
The annual average water quality of six rivers and lakes, such as Zhangfuhe, Tangxianghe and Baima Lake, reached the standard; The water quality of Shensanwei of Nanliutang River, the lake entrance sluice of Zhaogong River, Wangmupai Bridge of Wangmupai River and the north Hongsuzui of the drainage channel increased year-on-year, and the average water quality in flood season was eliminated.
V. Time limit for rectification
Before the end of December 2022.
VI. Rectification measures
(a) to carry out the flood season, the water quality is easy to decline in the upper reaches of the national and provincial examination sections, drainage pumping stations and culverts to intercept and store sewage.

(5) Strengthen encrypted monitoring and emergency response in flood season. Pay close attention to the rain and flood, and carry out encrypted monitoring of water quality in key sections. Strengthen the early warning of water quality, so as to find, dispose and eliminate problems early, and effectively prevent the decline of water environment quality. Strengthen the emergency duty of key rivers and sections such as Zhaogong River and Yubing River, which are prone to decline in water quality in flood season, find environmental hazards that may lead to a sharp decline in water quality in sections, start the response at the first time, and take effective measures to properly dispose of them.
VII. Completion of rectification
At present, various rectification measures have been put in place and the rectification objectives have been completed. In the month of July 2022, 11 national examination sections reached or were better than Class III sections, accounting for 45.5%, up 18.2 percentage points year-on-year; 57 countries and provinces accounted for 75.4% of the test sections reaching or better than Class III sections, up 15.8 percentage points year-on-year, ranking first in five cities in northern Jiangsu. During the flood season (June-September), the average water quality of the four sections of Nanliutang River, Shensanwei, Zhaogonghe Lake Entrance Sluice, Wangmupai River Wangmupai Bridge, and North Hongsuzui Drainage Channel were Class III, Class IV, Class III and Class III, respectively. In the same period of 2021, the water quality of the sections was Class IV, Class V, Class IV and Class IV, respectively, and the water quality of the sections was higher than that of 2021. The water quality of six sections, including Shunhe Bridge in Zhangfu River, Houying Bridge in Tangxiang River, Hongjin in Baima Lake, Tangcao in Xunhe River, Shensanwei in Nanliutang River and Wangmupai Bridge in Wangmupai River, all reached the standard.
