①Exhaust emission

According to “Emission standard of air pollutants for thermal power plant”(GB13223-2003),

“All new, enlarging or rebuilding projects whose EIA report have been approved before December, 31st of 1996, the first phase pollution emission control requirement is adopted”;

“All new, enlarging or rebuilding projects whose EIA report have been approved since January 1st, 2004, the third phase pollution emission control requirement is adopted”.

7# & 8# units are to follow the third phase criterion requirement above-said (GB13223-2003), in which SO2 is to be controlled under 400 mg/m3, dust under 50mg/m3, and NO2 under 450mg/m3.

②Waste water

HTTPP has no other wastewater discharged except ash wastewater, whose pollutants are simple SS, discharge into Xiaoqing River and Dashigan River directly. In December of 2006, “Integrated discharged standard of water pollutant of Xiaoqing River basin in Shandong Province” was issued, in which,

“All organizations who discharge wastewater into Xiaoqing River, except for city or town wastewater treatment plant, should follow the relevant regulation in the Table 1 in terms of wastewater pollutants concentration, and also follow the regulations in table 2, 3, or 4 according to phase”.

Hence, HTTPP is to apply its ash wastewater in the above-mentioned criterion in the important areas of DB37/656-2006, detailed values are list in table 1-6.

From coal analysis data, HTTPP usually used medium or low sulfur coal, and SO2 emission greatly reduced after desulfurizing establishments on No. 7&8 units.

(2) Water balance

In recent five years, water consumption keeps same since no units change. Wastewater and domestic sewage are sent to wastewater treatment station and then reuse to supplement cooling water, washing ash water and green watering. Washing ash water will deposit at ash tanker, upper liquid can be reused, and bottom condensed mud sent to ash site, discharging to Xiaoqing River, Dashigan River after deposition, detailed water balance is demonstrated in figure 2-6.

2.3 Pollution and treatment

HTTPP pays more attention to EP work, strictly carries out “three contemporary” rule during construction, to select high-level technically establishments to accord with EP requirement. Its electrostatic cleaners, limestone transportation system can arrive at advanced level at home so to ensure all indexes to meet pertinent criterions.

In daily production, HTTPP carefully comply relevant laws and regulations, to consider EP as a significant job to its existence. It has set up specific responsible system that plant director is the head to fully in charge, and specific leader will detailed implement safety supervision center as EMO, and to build EPM network so to form two-level system including plant and sector, also has perfect “environmental management standard”, and “quality, safety and environmental manual”, and etc, a series of environmental management rules.

HTTPP considers EP as industry continual development strategy, to consistently spend money on science and EP. It has spent total RMB 65 million Yuan on changing water dust catcher into electric dust catcher for No.1~6 units so dust emission can meet standard; It also spent nearly RMB 40 million Yuan on desulfurizing establishments for No.7&8 units, which were list in the fourth batch of particular fund in State Economic Trade Committee, and proposed projects in the second batch of “double advance and one excellence”. Desulfurizing establishments at No.8 unit is
