Introduction : CPCB Certification in West Bengal

There was a mid-sized chemical processing facility located in Howrah which held off from filing its compliance documents for about half a year, assuming that routine inspection would not take it to the next level. It became apparent that it was not going to be easy. There was a compliance notice issued by the West Bengal Pollution Control Board and partial restrictions on the operation along with stopping of the production process.

This is not a rare occurrence. In industrial belts such as Durgapur, Haldia and outskirts of Kolkata there is more regulatory oversight than ever before. Now it is imperative for industries to exhibit environmental responsibility both before and during their operations.
