Guidelines for Building Plan Submission

Industrial Siting Consultation (ISC)

The Industrial Allocation System (IAS) was setup in 2007 for the industry to consult NEA on proposed industrial siting considerations. As part of our efforts to upgrade the system to meet latest security requirements and replace obsolete hardware and software with newer ones, the IAS will be replaced by the Environment Protection Management System (EPMS) by Apr 2024.

We would provide another update once the transition from IAS to EPMS has been completed.  If you have any questions or concerns, please do not hesitate to email us at or submit them electronically via the Online Feedback Form at

Consultation on use of industrial premises

1.   Industrial developments should be sited away from residential premises. While pollution control facilities will ensure that air emissions, factory noise and effluent discharge comply with regulatory standards, residual or fugitive emissions of smell, dust and noise cannot be totally eliminated. These emissions could pose nuisance to residents whose homes are located close to the industries.

2.   To minimise such nuisance, adequate buffer distances must be provided between people’s homes and industries. Industries are classified into four categories: clean, light, general, and special. This classification is important for land-use planning: industrial estates close to residential areas are designated for clean or light industries, while those far away from residential areas, such as Tuas and Jurong Island, are for special industries that use large quantities of hazardous chemicals or can cause serious pollution. To protect our water resources, land within water catchments is zoned for clean or light industrial use.

3.   The prospective industrialist could consult DCD at an early stage to seek advice in order to comply with the following:

  • Adopt clean technology to minimise the use of hazardous chemicals and waste generation including processes that facilitate the recycling, reuse and recovery of waste.
  • Ensure industrial activity does not pose unmanageable health and safety hazards and/ or pollution problems.
  • Ensure installation of adequate pollution control equipment to comply with discharge or emission standards.
  • Ensure all wastes generated are safely manage and properly dispose of.

4.   More information on the siting requirements for industries and building pollution control requirements can be found in the Singapore Standard SS 593.

5.   The consultation form is available online at the following website address:

The consultation form can be accessed via Environment Protection Management System (EPMS) by Apr 2024 and we would provide an update once the transition from Industrial Allocation System (IAS) to EPMS is completed.
