DPCC Dust Control Compliance for Construction Site


As per Delhi Pollution Control Committee officials, the main reason, causing 30 percent of air pollution is all due to the dust that is eliminated from the construction sites. And, according to the Health Effects Institute’s report, it has been observed that a high rate of deaths are caused due to the air pollution containing dust and air pollution has become a third major cause of death in India.

Are you aware that why all of this is happening and for what all reason?

All of this is happening because of emissions from vehicles, dust releasing from construction sites, large power plants and refineries, vehicles, and stubble burning. In addition to it, the construction of new buildings, residential societies and ongoing projects have also been playing a crucial role that is resulting in damaging the air quality.

What can be done for avoiding the harm caused to our planet?

The National Clean Air Programme (NCAP) of India has made it easy and somewhat manageable to control the harm caused to our environment’s health. As under it, a target has been set of 20-30% reduction of pollution by 2024, taking 2017 as a base year. The National Clean Air Programme (NCAP) has come with the aim to:-

  • Increase an effective ambient air quality monitoring network;
  • Efficient data dissemination and public outreach management;
  • Devising a feasible management plan for prevention, control and abatement of air pollution

All of this has been aimed with the hope to achieve the good air quality. Not only this, but for reducing the dust emission “Advancing Better Air Quality with Clean Construction” toolkit has been developed by the Clean Air Asia (CAA) to cure the same. In order to enhance the capacity building for stakeholders involved in construction activities such as Architects, Civil Engineers, Project Management Professionals, Construction Professionals, State Pollution Control Board and local governments.

Guidelines for reducing dust pollution

Construction and Demolition Waste Rules, 2016 prescribed various guidelines for all construction sites to prevent dust pollution in the capital city of India. The guidelines are as follows:-

  1. Dust/wind breaking walls of appropriate height around the periphery of the construction site.
  2. Installation of Anti-Smog Gun (s) (For > 20,000
  3. Tarpaulin or green net on scaffolding around the area under construction and the building.
  4. All vehicles including carrying construction material and construction debris of any kind should be cleaned and wheels washed.
  5. All vehicles including carrying construction material and construction debris of any kind should be fully covered and protected.
  6. All Construction material and debris of any kind should be stored on the site and not dumped on public roads or pavements.
  7. No loose soil or sand or Construction & Demolition Waste or any other construction material that causes dust shall be left uncovered.
  8. No grinding and cutting of building materials in open areas. Wet jets should be used in grinding and stone cutting.
  9. Unpaved surfaces and areas with loose soil should be adequately sprinkled with water to suppress dust.
  • Roads lending to or at construction sites must be paved and blacktopped i.e. metallic roads (for > 20,000 sq. mt built-up area)
  • Construction and demolition waste should be recycled on-site or transported to an authorized recycling facility and due record of the same should be maintained.
  • Every worker working on construction and sited involved in loading, unloading and carriage of construction material and construction debris should be provided with dust mask to prevent inhalation
  • Arrangement should be provided for medical help, investigation and treatment to workers involved in the construction of building and carry of construction material and debris related to dust emission.
  • Dust mitigation measures shall be displayed prominently at the construction site for easy public viewing.

Preventive Measures

There are certain dust control measures designed for all types of activities to cure the air quality. Let us get to know about each of them in detail. The dust control measures are as follows:-

  1. Measures during demolition
Debris during demolitionConstruction site should be screened with appropriate screens or sheets as directed by CPCB/NGT/PCB at least 3m height or 1/3rd of the building height and maximum up to 10m
Before and during demolitionASG machine made compulsory for > 20,000 built-up area)

Water/ chemical suppressant spraying should be carried out before and during demolition

Dropping materials to ground levelEnclose chutes, and skips will help in reducing dust emissions. Sufficient water supply needs to be carried out to increase the moisture content.
Removal of material from the siteMaterials should be removed from the site right after finishing the task. Prolonged storage of construction debris on site or exposure to the wind should be avoided.
Crushing of material for reuse, transportation or disposalActivities like crushing should be sited as far away possible from sensitive receptors
AsbestosAsbestos needs to be removed before demolition
Biological materialBiological material should be removed before demolition.

Due care must be taken so that the material does not become airborne, but is sufficiently contained

2. Measures during material handling

Material handling operationsAlways keep the number of handling operations to a minimum by ensuring that dusty material isn’t moved or handled unnecessarily
Handling areasKeep clean and free from dust
Vehicle loadingUse material handling methods that reduce the generation of airborne dust
Reduce dust generation by using water removal of materials from the siteMaterial needs to be removed from the site as soon as it is practical. Prolonged storage of construction debris on-site or exposure to wind should be avoided
Dust dispensary over the site boundaryUse static sprinklers, bowsers, handheld hoses and other watering methods as necessary
Chutes, skips and conveyor transfer pointsDrop heights should be kept to a minimum and enclosed wherever possible to reduce dust generation with water
Transport of fine powdery materialsVehicle must be fully covered and protected

3. Measures during material storage

Bulk Cement/fine aggregate material storageDelivered by tanker or vehicle covered with a sheet stored in covered space
Accidental spillages when fillingMethods and equipment for cleaning must be in place. If necessary, include the use of audible and visual alarm systems.
Fine, dry materials

(less than 3mm in particle size)

Store inside buildings or cover with adequate protection from the wind e.g. by using sheeting
Storage LocationStore material or stockpiles away from the site boundary and sensitive receptors whenever possible e.g residential, commercial and educational buildings, places of public access or other features, such as watercoures;
Storage/stockpiles protecting from wind erosionWhere possible, ensure stockpiles are kept enclosed or covered under sheeting. Dust generation from dusty materials can be reduced by using suitable and sufficient water sprays, wind barriers of similar sizes and height to the stockpile may be used.
Cleaning upClean up using wet handling methods.

4. Measures during Operations (Cutting, Drilling & Sawing)

Cutting, grinding, drilling, sawing, trimming, planning, sandlingThe following measures should be in place at all sites to comply with best practices: pre-wash work surfaces, screen-off work areas, and sweeping away

Spraying water, preferably from a water efficient spray pump,over the material as it is being cut greatly reduces the amount of dust generated


Local exhaust ventilation should be used where possible for better health of workers

Façade CleaningSilica-free material should be used for abrasive cleaning since the inhalation of silica dust is harmful.


Wet processes should be used wherever possible. These introduce water into the air/grit stream, greatly reducing the dust hazard to both building occupier and the general public

Painting and decoratingVacuum cleaning should be used wherever possible.

Sanding and cutting machinery should be fitted with dust suppression or collection equipment

Fitting out-plastering, rendering, decorative finishing, furniture fittingCutting and sanding machinery should be fitted  with dust suppression/ collection equipment
Vacuum cleaning should be used whenever possible.
Cleaning processDry sweeping should be avoided and only carried out with vacuum extraction methods attached.


Washing and damping down should be carried out whenever required

5. Measures during C&D Waste Management

C&D ActivitiesUse of ASG sand dust suppressant


Proper implementation of guideline on dust mitigation measures


Self-assessment through DPCC C&D Self Audit Web Portal

StorageAll areas for storing C&D wastes/ construction material needs to be demarcated and preferably barricaded particularly those materials that have potential to be dust borne.


Prohibiting open storage of C&D material and enforcement


Contractors/ builders/ sellers/ related stakeholders prohibited from storing/ dumping C&D wastes/ construction material on road as it obstructs traffic flow


Store any materials away from sensitive receptors in covered areas. Water sprinkling/ fine spray from nozzles to suppress dust re-suspension at site

Loading/UnloadingAreas where loading/ unloading (fugitive dust) activities to be demarcated and located should be in such a way that dust dispersal is minimized.
Reuse/recycleLabel all waste storage areas and skips, detailing the type of waste


Use recycled materials and recycle any materials used on site rather than disposing them which includes timber, aggregates, soil, tarmac, bricks, masonry, concrete and glass.

Deposition of construction wasteEvery C&D waste generator must keep the construction and demolition waste within the premise or get the waste deposited at collection centre provided by local government or handover it to the authorised C&D waste proceeding facilities of construction and demolition waste; and ensure that there is no littering or deposition of waste.

6. Measures during vehicle movement, routes & emission from vehicle

Construction and maintenance of unsurfaced roads & speed of vehiclesKeep roads/ ways in compacted condition using static sprinklers, commercially available additives. Suppressants

All vehicle should be fully covered and protected

Slow movement of vehicles generates less dust, introduce speed limits

Walkways and surfacesClean regularly using wet methods and not dry sweeping
Vehicle waiting areas and hard standingsRegularly inspect and keep clean by brushing or vacuum sweeping

Sprinkle water regularly to maintain surface moisture if needed.
