Pollution N.O.C. Requirements for Industries in India

Compliance with environmental laws has become one of the most challenging tasks that every industries/commercial establishments/businesses operating in India faces today. Operating a manufacturing unit/factory/warehouse/project/construction activity/industry without obtaining all the required environment approvals or neglecting the same can lead to severe disruption to your business.

Pollution N. O. C. is one such regulatory requirement which enables you to certify that you have complied with all the pollution control requirements as per law. Generally, industries/commercial establishments/businesses have to take approvals for air emissions, effluent discharges, hazardous waste management etc., from respective environmental regulators prior to commencement of their activities/operations.

Entrepreneurs spend significant time and effort towards production/investment/expansion plans and hardly pay any attention towards environment clearances unless and until they get a notice from the Pollution Control Board saying that your factory needs comply with certain requirements or face shutdown. By the time you get the notice your problem is either of non-compliance, documents, inspection or stopping of your operations.

Consent to Operate (CTO)

This permission comes into action after you have established your industry/unit and before you commence commercial operations. It states that the operations conform to the pollution control standards.

Depending on the category of industry your business falls under, State rules and directions from concerned pollution control board the requirement could be any of the above or both.

What Common Problems Do Businesses Face Regarding Pollution N.O.C.?

In most cases companies run into problems not because they wilfully ignore rules but because they have not taken environmental considerations into account while expanding or setting up plant initially.

Typical problems are :

Delayed Consent Approval :

Consent Applications are delayed for reasons such as incomplete applications, missing documents, objections received on scrutiny and requests for further clarifications.

Variations Between Approved Activity and what is actually done :

Approval may have been taken for certain specific activity initially but subsequently increased production, change of process or even starting a new activity. Such modifications have to be assessed afresh for compliance with applicable norms.

Issues related to Pollution Control Equipment :

During scrutiny pollution control boards may investigate whether pollution control equipment provided is commensurate with the nature and extent of activity being carried out. Often times inadequate provisions lead to problems.

Issuance of Notices by Pollution Control Boards :

Pollution Control Boards may serve notices for non-compliance of conditions of consent or failure to meet environmental norms. Each notice has to be dealt with on its merits and the facts coupled with applicable rules.

How Can Pollution N.O.C. Issues Affect Industries and Companies?

Environmental compliances are issues that affect businesses in the following manner:

The concerned unit or factory runs the risk of getting disturbed by authorities if they sense major issues in compliances.

Final Thoughts

Clearances from environmental regulatory authorities have increasingly become part of the responsible conduct of business. Running a company involves not just commercial planning and execution but compliance with regulatory requirements as well.

A Pollution N. O.C. is one way of demonstrating that the environmental requirements applicable to the operations of a company have been considered. But obtaining the approval is just the first step. Compliance with the conditions of consent, record keeping, and responding to regulatory queries as and when they occur form part of the ongoing responsibilities.

Businesses, industries, factories, construction projects, and commercial activity owners should consider their environmental requirements before commencing activities, expanding operations, or even undertaking commercial transactions.

Often legal issues get complicated for businesses because they seek legal advice only after notices are received or difficulties are encountered in running the operations. A review at an early stage would help identify problems with documentation, regulatory issues and exposures, and areas of potential concern.
