BLUE SKY ACTION PLAN , 2001-2004
Target Annual rate of Class II to 80 by 2004

• Major measures
• Promote the proportion of clean fuel energy and
  enhance low-sulphur coal Built coal-free area of
  total approx. 400km2 from 2001 to 2004
• Cut off the all of small coal boilers below
  tons / hour by 2002 and 10 tons/hour by 2004,
  boost up central heating network.
• Improve the efficiency of dust removal and
  desulphurization in coal-burning equipment
• Implement the total pollutant load control of
  air emission

13
Major measures (cont.)

• Implement total pollution load control for air
  pollutants
• Increase the road sweeping and washing rate and
  trucks leak free transportation
• Enhance management for construction sites to
  control wind-borne dust from open sources.
• Grow afforesting and greenland to 35 of urban
  area by 2004
• Strengthen annual examination and road
  supervision of auto-emission
• Actively develop public transportation and clear
  fuel vehicles
