Potential Impacts to Specific Sites and Mitigation

Potential Impacts to Specific Sites and Mitigation

At some sites, there are environmental risks that are a result of the sites unique environment, or the particular investments to be made at the site.

1. Risk of Overdevelopment in the National Scenic Areas

In Guizhou, it lies 13 national level scenic areas. The Construction Department manages designated scenic areas with responsibilities delegated to the relevant administrative levels.

2. Guanlin National Geo-Park

A. Risk
An exhibition hall of triasichthyosaur will be constructed in the core area of the geo-park, taking a footprint of 3500 m². In addition a rock and green area of trias park will be constructed in the central development area of the geo-park. The two structures themselves may pose potentially impact on the landscape in such areas as an integrated part of the park. Furthermore, construction activity of the two structures will cause potential impacts to the fragile fossil resource through viberation of equipment such as piling and movement of construction vehicles. Increased tourists flow will pose another potential impact on the valuable natural resource of fossils which may be vandalized or damaged if the tourists are away from the designated routes.

• 
  Architechtural style or color should be consistent with the surrounding environment;
  
• 
  Siting of the two structures should be carefully selected and confirmed by archeological investigation;
  

• 
  A procedure of construction management associated with fossil protection should be established ;
  
• 
  Construction activity should be immediately stopped if any cultural property is found and the regulatory department should be informed to assess the property. Construction should not be continued without the permission of the regulatory department on cultural property;
  
• 
  Access road to the construction site should be carefully selected to avoid the sensitive areas potentially having fossils resource;
  
• 
  Educational program should be provided to the contractor on the importance of the protection of the fossile resource;
  
• 
  Competent contractor should be selected to undertake the works so as to minimize the impact on the fossil resource;
  
• 
  Enhance environmental awareness by posting signs and provide training to tour guides;
  
• 
  Control the number of tourists to the core area;
  
• 
  Education programes should be provided to the tourists on the importance of the heritage protection.
  

3. Xingyi National Geo-Park

A. Risk
A fossile museum of Guizhou Dragon will be constructed within the park with a footprint being 10,000 m². As with Guanlin Natinal Geo-park, the visual impact of the structure, and the construction impacts, and the cultural heritage damage impact are of great concern for this component.

• 
  Architechtural style or color should be consistent with the surrounding environment;
  
• 
  Siting of the two structures should be carefully selected and confirmed by archeological investigation;
  

• 
  A procedure of construction management associated with fossil protection should be established; Construction activity should be immediately stopped if any cultural property is found and the regulatory department should be informed to assess the property. Construction should not be continued without the permission of the regulatory department on cultural property;
  
• 
  Access road to the construction site should be carefully selected to avoid the sensitive areas potentially having fossils resource;
  
• 
  Educational program should be provided to the contractor on the importance of the protection of the fossile resource;
  
• 
  Competent contractor should be selected to undertake the works so as to minimize the impact on the fossil resource;
  
• 
  Enhance environmental awareness by posting signs and provide training to tour guides;
  
• 
  Education programes should be provided to the tourists on the importance of the heritage protection.
  

4. Wanfenglin National Scenic Area

A. Risk
A 50 km pathway will be constructed along the Nahui River with the associated works to rehabilitate river banks. The Nahui River is an integrated part of the scenic resource in the scenic area, thus any construction activities near this river should be carefully managed so as to minimize the impact on the river, i.e. wastewater from workers’ camps and prevent construction materials from falling into the river. 10 camps will be installed along the route near the domestic settlements for visitors to stay overnight, with the land occupation for each camp being 5,000 m².. The domestic wastewater and solidwaste would be created in these camp sites which will pose serious impact on the surrounding environment. The pathway for walking and biking within the scenic area is 250 km which partially upgrades the original paythway and convert some to recreational sites for horse riding and bull fighting. Construction of these sites and pathways may disturb the ground vegetation and operation of these sites may lead to damage to the eco-system.

• 
  Sites for recreational activities should be carefully selected to avoid ecologically sensitive areas;
  
• 
  Educational programes should be provided to construction team on environmental protection in scenic area;
  
• 
  Workers’ camps should be away from the Nahui river;
  
• 
  Spoils and solid wastes should be collected and stored in a designated site away from the river and transported out of the site regularly;
  
• 
  Construction sites for the recreational camps and sites for bull fighting, etc. should be fenced and minimized to reduce the disturbance on the ground vegetation;
  
• 
  Wastewater and solid waste collection system should be provided in each of the recreational camps;
  
• 
  Boundary of each camp should be clearly indicated in posts;
  
• 
  Enhance environmental awareness by posting signs and providing training to tour guides;
  
• 
  Routes for walking and biking should be carefully selected to avoid ecologically sensitive areas;
  
• 
  Treated effluent from the WWT facilities should be reused for grassland or forest irrigation which are remote from surface waters or important groundwater aquifers.
  
• 
  The visitors should be banned from entering into the area applied with treated effluent with posting warnings.
  
• 
  Excess sludge from the WWT facility should be transported to the landfill in the county for landfill.
  

5. Shamu River National Scenic Area

1. 
   Risk
   

The Port proposed to be constructed on the Liangcha River will occupy an area of 800 m², and a concrete bridge of Niejiayan with a span at 100 m to be constructed over Shamu River. Construction of these works will have severe impact on the water quality. Construction materials falling into the river and the disturbance of the river sediments by the construction of underwater works are exemples for such impact. Visitors boating on the rivers may cause littering of solid wastes into the river.

• 
  Construction activities should be scheduled to concentrate on low flow season;
  
• 
  Construction sites for the underwater works should be dammed to minimize the disturbance of the river sediments;
  
• 
  Construction of the deck of the bridge should be well managed to avoid falloff materials into the river;
  
• 
  The construction solid waste arising from pier construction should be collected and conveyed to designated place for safe disposal in timely manner;
  

• 
  Enhance environmental awareness by posting signs and providing training to tour guides;
  
• 
  Treated effluent from the WWT facilities should be reused for grassland or forest irrigation which are remote from surface waters or important groundwater aquifers;
  
• 
  The visitors should be banned from the area applied with treated effluent with posting warnings. Excess sludge from the WWT facility should be transported to the landfill in the county for landfill.
