CA provisions about the Dust pollution by road construction work and it’s mitigation measures
-
As per clause 2.3 of schedule -D, All crushers used in construction site shall conform to relevant dust emissions control level. The control measures shall conform to stipulation of APPCB’s CFO.
- As per clause 2.1 of schedule -D, Generation of dust: All vehicles delivering materials should be provided with tail guard and shall be covered to avoid spillage of materials and dust blowing off the load.
- No fugitive dust emission at settlement sites arising from maintenance activities shall be allowed. All such operation leading to dust pollution in settlement areas shall be performed with necessary dust suppression by adequate water sprinkling. Such mitigation measures to be taken to ensure that no dust pollution arises from construction stock piles.
-
Also, clause 3 of schedule-D of the concession agreement All crushers used in construction shall conform to relevant dust emission control legislations.

Sample site instructions on Dust pollution by road construction work in project highway camp office, and carriageway.
Case-1 Subject: Dust pollution by road construction work in project highway camp office-reg.
|
To The concessionaire Subject: Dust Pollution by road construction work in project highway camp office-reg.
We had noted that the dust pollution level is very high at project highway camp site. This is due to non use of bag house filter in the crusher plant. You are being instructed to take preventive measures to control dust pollution with immediate effect. As it is affecting people working in and around the camp area. Thanking you, |
Case -2 Dust pollution by road construction work on construction sites-reg
|
To The concessionaire Subject: Dust Pollution by road construction work in project highway camp office-reg.
Dust pollution occurs due to construction activities at this location. Measures must be taken to minimize the generation of dust at the construction site. This is to create a safe environment for workers as well as existing road users. Also, all activities leading to dust pollution in the areas are carried out with necessary dust suppression by adequate water sprinkling. Thanking you, |
Case -3 Dust pollution by road construction work on BC overlay construction sites-reg
|
To The concessionaire Subject: Dust pollution by road construction work in highway while surface preparedness works for BC overlay -reg.
it is observed that, dust generation at surface preparedness works for BC over lay part is too high. Measures should be taken to reduce such dust generation, especially at work sites in residential/habitation areas. This is to create a safer environment for workers as well as road users. Also, all the activities that lead to dust pollution in the area should be done with adequate dust suppression by sprinkling water. Or the cleaning work should be done at night some extent advanced. Thanking you, |
Case -4 Measures shall be taken to minimise the generation of Dust pollution by road construction work at construction site and diversions zones-reg
|
To The concessionaire Subject: Instruct to maintain the riding surface on diversions at construction zones-reg.
Measures shall be taken to minimise the generation of dust at construction site in aid to create safe environment to workers as well road user. Also All the activities leading to dust pollution in areas shall be performed with necessary dust suppression by adequate water sprinkling. Further, it is to be maintained the riding surface of diversion in satisfactory condition until the traffic detour to normal state and be kept it free of dust, potholes and other pavement distresses by undertake the requisite house keeping, maintenance activities on priority with frequent intervals. it is to clear the occupied spillage material and distresses over the riding surface between km.16+760 and 16+960 on urget basis. This action for maintain a safe conditions/environment for the users as it seems catastrophic. Thanking you, |
Case -5 Reminder notice to minimise the generation of dust at construction site and diversions zones-reg
|
To The concessionaire Subject: Reminder notice for maintenance of riding surface on diversions at construction zones-reg.
No mitigation measures are put in to control the dust emissions at construction site. Shall take effective steps in place against dust problems to reduce the level of dust emission. Thanking you, |
