Introduction

• Singapore developed industrial base achieved
  high economic growth in short span
• Programmes implemented at early stage to protect
  environment

3

• Environment quality compares well with best
  cities in the world
• Major air pollutants within international
  standards
• Inland and coastal waters support aquatic life

4
Pollutant Standard Index (PSI)
5
Management Strategy

• Prevention
• Enforcement
• Monitoring
• Education

6
Prevention

• Planning Control
• Land use planning
• Judicious siting of industries
• Environmental Infrastructure
• Comprehensive sewerage system
• Efficient solid waste system
• Pollution Control
• Air and water pollution control measures

7
Land Use Planning

• Consultations between URA and NEA on land use
  planning
• Land is zoned for specific uses such as
  residential, commercial, industrial, etc.
• Environmental controls are factored into the
  planning

8
Environmental Control

• Safeguarding land for drainage, and facilities
  for collection, treatment and disposal of
  wastewater and refuse
• Protection of water catchments
• Compatibility of land use

9
Siting of Industries

• To optimise land use
• site industrial estates for clean and light
  industries close to residential areas
• site general and special industries farther away
  from residential areas in Jurong and Tuas
  Industrial estates, and on Jurong Island

Land Use Zoning
11
Sewerage System

• Separate sewerage system for wastewater and open
  drainage for rain water
• 6 water reclamation plants
• 3,140 km sewers
• More than 100 pumping stations
• served all industrial estates almost all
  residential premises except for isolated pockets
  of residential premises with on-site sewage
  treatment plants

Solid Waste Management

• Daily refuse collection service
• 90 of wastes disposed off at 4 incineration
  plants
• 10 of wastes disposed off at the off-shore
  Semakau sanitary landfill

Air Pollution Control

• Licences for scheduled premises
• Industries designed or provided with pollution
  control equipment to comply with allowable
  emission standards for air pollutants
• Fuel burning equipment to use fuel of specified
  quality
• Open fire prohibited

Vehicular Emission Control

• Set stringent emission standards for registration
  of new vehicles
• Require use of cleaner fuel
• Require mandatory periodic inspection of in-use
  vehicles
• Take stringent enforcement action against smoky
  vehicles
• Promote education on proper vehicle maintenance
  to prevent smoke emission

21
Water Pollution Control

• Trade effluent pre-treated to allowable discharge
  limits for discharge into a public sewer or
  watercourse
• Industries may pay tariffs for the discharge of
  trade effluent containing biodegradable
  pollutants into the public sewer
• Containment facilities provided for storage tanks
  of oil and chemicals

25
Enforcement

• Conduct regular checks on industries
• Air pollutants to comply with emission standards
• Trade effluent to comply with standards for
  discharge into sewers/watercourses
• Control, management and disposal of hazardous
  substances and toxic industrial wastes

26
Checking air emission levels at a factory
27
Management Strategy

• Prevention
• Enforcement
• Monitoring
• Education

28
Monitoring

• Regular monitoring of ambient air quality, and
  inland and coastal waters
• Assess adequacy and effectiveness of control
  programmes
• Monitor the trend of air and water qualities
• Carry out regular review of policies and emission
  standards with extensive consultations with the
  public and industries

Education

• Work with industries as partners to move towards
  self-monitoring and co-regulation
• Dialogues with industries, professional
  institutions, etc
• Training courses for professionals, industries,
  etc
• Seminars, workshops, etc, for industries,
  businesses, etc
• Public campaigns, e.g. Clean and Green Week
