ring the river in 2005 will be limited to 368,000 tons a year and the whole water body will progressively become cleaner;.
• in the Haihe River basin, the total volume of COD discharge in 2005 will be restricted to 1,030,000 tons a year and water used as potable water supply will meet national standards for surface water quality; and
• in the Liaohe River basin, the volume of COD discharge in 2005 is not to exceed 240,000 tons a year.
3.2.2The Three Lakes
The principle environmental targets to be reached in 2005 are:
• for LakeTaihu, total COD discharge is to be limited to 194,938 tons a year, total nitrogen discharge is not to exceed 13,023 tons a year, total phosphorus is to be restricted to 3470 tons a year and water quality in rivers flowing into or out of the lake is to be close to Grade III standard for surface water;
• for Lake Dianchi, total COD discharge is to be limited to 7177 tons a year, total nitrogen discharge limited to 5012 tons a year, total phosphorus discharge restricted to 514 tons a year and water quality in Waihai is to meet Grade III standard for surface water. Water quality in Caohai is to be close to Grade IV standard for surface water;
• for Lake Chaohu, total COD discharge is capped at 59231 tons a year, total nitrogen discharge limited to 11351 tons a year, total phosphorus discharge limited to 1072 tons a year and the quality of water entering the lake is to meet or almost meet Grade III standards for surface water. Water flowing out of the lake is to meet Grade III standards.
3.2.3 Acid Rain Control Zone and SO2 Control Zone
In 2005, the limit on SO2 emissions in the “two control zones” is to be 10,280,000 tons and sulphur deposition nation-wide is to be reduced to some extent. Acid rain pollution in the acid rain control zone is to be reduced. The area affected by precipitation of pH less than 4.5 will be 5% less than that during the 8th five-year plan period. By 2005, SO2 concentration in urban air within the “two control zones” will meet Grade II standard for air quality.
3.2.4 Beijing Municipality
Beijing municipality will aim to integrate social, economic and environmental development objectives. By 2005, water quality, air quality and noise levels in Beijing are to meet the relevant national standards. Environmental damage is to be reduced and the natural environment in some surrounding counties and regions will be improved. In addition, environmental investments in Hebei Province, Inner Mongolia Autonomous Region and Tianjin Municipality will be increased to indirectly improve environmental quality in Beijing.
3.2.5 Bohai Sea
By 2005, the total volume of COD entering the Bohai Sea will be limited to 3,389,000 tons, and total nitrogen and total phosphorus input will be restricted to 107,000 tons and 87,000 tons respectively. Environmental pollution and ecological damage will also be brought under control.
3.2.6Major Municipalities
The major targets for environmental protection in these areas include:
• the 47 major municipalities and municipalities identified in the 9th five-year plan period and which host demonstration projects are to strengthen their efforts concerning the “one control and two meeting standards”. Water and air quality, and noise levels in these municipalities are to conform to the relevant national standards;
