(1) Rectify industrial coal-fired enterprises.

1. Focus on rectifying coal-fired enterprises such as power plants (thermal power plants).

(1) Immediately shut down the two 50,000-kilowatt small thermal power units of the Banshan Power Plant.

Banshan Power Plant’s annual coal consumption is about 1.27 million tons. Its two 50,000-kilowatt units do not have desulfurization facilities. They are small thermal power units that were shut down by the state within a time limit in 2003. However, the plant has no plans to shut down so far. The relevant departments of the provincial government should be requested to coordinate and resolve this matter and shut down the two units before the end of December 2003. This work is led by the Municipal Economic Commission and coordinated by the Municipal Environmental Protection Bureau.

(2) Promptly implement the flue gas desulfurization treatment project for the two 125,000-kilowatt units of Xiaoshan Power Plant. The annual coal consumption of Xiaoshan Power Plant is about 800,000 tons. Relevant departments of the provincial government should be requested to coordinate and resolve this matter and complete the flue gas desulfurization treatment project before the end of 2004. This work is led by the Municipal Economic Commission and coordinated by the Municipal Environmental Protection Bureau.

(3) Strengthen the management and rectification of medium and low-level pollution sources, especially the treatment of flue gas desulfurization and dust removal from thermal power enterprises.

There are 21 thermal power plants (stations) and 75 boilers in the urban area of ??Hangzhou, with an annual coal consumption of about 2.25 million tons. They must implement flue gas desulfurization and dust removal projects before the end of 2004. Establish an online monitoring system for smoke, dust and gas. Calculated based on a sulfur content of 0.6%, the desulfurization efficiency must be greater than 70%, and it is required to complete 50% in 2003 and 50% in 2004. The Municipal Economic Commission and the Municipal Environmental Protection Bureau are responsible for supervising the implementation of this work.

2. Pay close attention to adjusting the industrial and product structure of Hangzhou Iron and Steel Co., Ltd., and shorten and stop the coke and pig iron production lines. Hangzhou Iron and Steel Co., Ltd. consumes nearly 1.03 million tons of coal annually. The use of scrap steel to make steel accounts for about 1/3 of the total, and the remaining 2/3 is made from iron ore. A large amount of smoke, sulfur dioxide and nitrogen oxides are emitted during coking, pelletizing, sintering, iron-making and other processes (of which the amount of coal used in coking reaches 700,000 tons/year). It is still difficult to effectively collect and control; the smoke and dust of the sintering machine seriously exceeds the standard. According to a report from the Hangzhou Environmental Monitoring Center Station, the amount of atmospheric dustfall in the mid-mountain area is four times that of the main urban area.

Relevant departments of the provincial government should be requested to coordinate and resolve the industrial and product structure adjustment issues of Hangzhou Iron and Steel. Hangzhou Iron and Steel Co., Ltd. is required to implement clean production processes to ensure an average annual reduction of 15% in pollutant emissions, relocate seriously polluting coke and pig iron production lines, solve the problem of serious excessive smoke and dust in sintering machines by the end of December 2003, and eliminate a coking plant built in 1975 in 2004. furnace, another coke oven will be eliminated in 2005, and the required coke can be purchased from outside; two iron-making blast furnaces will be closed before the end of 2005, and the last iron-making blast furnace will be closed before the end of 2010. This work is led by the Municipal Economic Commission and coordinated by the Municipal Environmental Protection Bureau.

(5) The Municipal Housing Authority and the Bureau of Land and Resources shall be responsible for the prevention and control of dust pollution at demolition sites in accordance with their respective management responsibilities, and carry out careful supervision. The project budget estimate of the demolition unit should include the cost of dust pollution prevention and control, the cost of the demolition project enclosure, the cost of the dense mesh enclosure on the street and the densely populated side, etc., and ensure that the earmarked funds are used exclusively.

2. Manage and control road dust.

(1) The Municipal Urban Management Office should strengthen the management of waste transportation enterprises in the city. Before the start of the construction project, the construction unit must go to the local city appearance and environmental sanitation administrative department to handle the project waste disposal procedures, and formulate a transportation unit (self-employed household) permitting system: it is necessary to increase the intensity of waste transportation management and resolutely prevent " Throwing, spilling, dripping and leaking” phenomena occur.
