Dear Mr. Dass
First of all, your company is coming under which control, (state or central).
Accordingly approach Tamil Nadu Pollution control Board or Central Pollution Control Board office for proper guidance.
While approaching go with all necessary documents about your company, how it will emit pollution in the environment. What are the precautions you are observing to have control on pollution.
You can ask them to guide. If our approach is in correct way, surely we will get proper support and guidance for every work we required to be done.
With warm regards
