All existing industrial sectors are classified into four categories, namely, red, orange, green, and white categories. The Ministry of Environment carries out this classification, Forest and Climate Change, to differentiate between industries with the highest pollution index and those with the lowest.
Red category: The industries with the highest pollution index belong to the red category in the sense that it generates the highest amount of emissions, effluents, and hazardous waste, and consumes the highest percentage of resources. Industries like large-scale manufacturing industries, international restaurants, and super-speciality hospitals come under the red category with the largest amount of pollutants flushed out into the atmosphere. According to a press release by the Environment Ministry, industrial sectors having a pollution index of 60 and above belong to the red category.
Orange category: Medium-sized industries with a pollution index score of 41 to 59 belong to the orange category, with comparatively reduced levels of pollutant emissions. The orange category includes industries like cashew nut processing, coffee seed processing, pharmaceutical formulation, fish processing and packaging, ply-board manufacturing, automobile servicing and repairing, tobacco products manufacturing, thermocol manufacturing, spray painting, and such.
Green category: Industries with a low pollution index score of 21 to 40 belongs to the green category. Industries including but not limited to small bakeries, storage of food grains, leather footwear, and products, cement products, ceramic colour by mixing, glue from starch, flour mills, tires or tubes retreating, small hotels, sawmills, phenyl/toilet cleaners, poultry, hatchery and piggery, gold and silver smithy, tea processing are all industries belonging to the green category.
White category: A fairly new classification, industries belonging to the white category are practically non-polluting, with the lowest pollution index score of anywhere up to 20. Biscuit trays, rolled PVC sheet (using automatic vacuum forming machines), cotton and woollen hosiery making (without dyeing or washing), electric lamp (bulb) and CFL manufacturing, scientific and mathematical instrument manufacturing, handloom or carpet weaving, coir items from coconut husks, organic manure are all industries belonging to the white category.
Eligibility Criteria for Obtaining Pollution License/CTO:
The categorization of industries into four based on their respective pollution index score has helped in ensuring that any industry is constructed and operated in a manner consistent with environmental policies and objectives. The introduction of the fourth category of white non-polluting industries has urged industrial sectors to adopt cleaner manufacturing methods, hence leading to lesser pollution. Such categorization has also prompted industries to self-assess themselves and their manufacturing and waste management methodologies.
The following industries are eligible to apply for a pollution license/CTO:
Industries belonging to the red category must mandatorily acquire pollution licenses and will not be permitted to function in ecologically fragile or protected areas.
Industries belonging to the orange category.
Industries belonging to the green category.
Industries belonging to the white category do not require the CTO or CTE. Such industries only need to intimate the concerned SPCB or PCC prior to construction or operation initiation.
Pollution Index:
The categorization of industries into red, orange, green, and white is based on the industries’ pollution index score. “Pollution index is a function of the emissions (air pollutants), effluents (water pollutants), hazardous wastes generated and the consumption of resources.” This classification is also based on the number of raw materials used, the process of manufacturing, and the number of potential pollutants. In the current categorization, 60 industries belong to the red category, 83 to the orange, 63 to the green, and 36 industrial sectors to the white category of non-polluting industries.
Even though the industries belonging to the white category do not require a CTO/CTE or a pollution license, these industries must satisfy the following criteria:
The industry must be located in the industrial zones/estates demarcated for the purpose.
Only up to INR 1 crore is invested in the industrial plant and its machinery.
The industry will emit any form of pollutants, including air, water, chemicals, to any stream/well/sewage or cause noise pollution.
Documents Required For CTO/CTE:
Given below is a list of general documents that must be furnished for obtaining a CTO/CTE.
Satellite image of the project location
The layout of the project location
Project report with details of manufacturing methods and raw materials
Proof of Investment
Environmental statement
NOC Compliance report/Consent conditions in the form
Certificate of completion of the effluent treatment plant or add-on pollution control
Compliance with Environment clearance criteria
For water consent/NOC:
Compliance with water consent clauses
Reports of treated wastewater analysis
Water cess returns
Effluent Treatment Plant report/Sewage treatment plant report
The layout of the effluent treatment plant and sewage treatment plant
For air consent/NOC:
Specifications of air pollution control facility
Drawing of monitoring facility
Report of emission analysis
Compliance with air consent clauses
For authorization of chemical/hazardous waste:
For information on documents to be furnished for obtaining a CTE (consent to establish) will be available on your State’s pollution control board website. If an individual fails to obtain a CTE/CTO or Pollution license, they will be subject to 6 months to 1 year of imprisonment, with chances of a 6-year extension and penalty charges.
How to Apply for A Pollution License:
Obtain NOC/CTE
Submit an application with site details, plans for pollution control, and industry registration certificates to the state pollution control board’s regional officer. NOC may be obtained from regional officers.
You may submit your application online by logging onto your State’s pollution control board’s website.
