  • To abide Interim National Water Quality Standards of Malaysia as to maintain the water quality under Class 11B6.
  • Temporary workers houses will be placed 30m away from the river side and the workplace will be placed 50m away.
  • Extra earth will be placed 30m away fromthe river side and sedimentation pond will be provided.
  • Working on daytime from 7am to 5pm. Noiselevel will not exceed 55dBA from 8am to 6pm and 45dBA from 6pm to 8am.
  • Control the speed of vehicles, especially during dry period to reduce dusty surfaces.
  • Solid waste or plants debris not bethrown into drainage, pond or river. Solid waste collection must be placed 30maway from the river and liquid collection, especially oil and toxic must beplaced 50m away.
