What is TNPCB?

The TNPCB was established under the provisions of the Water (Prevention and Control of Pollution) Act, 1974, and the Air (Prevention and Control of Pollution) Act, 1981. It is responsible for:

  • Monitoring air, water, and soil quality.
  • Regulating industrial pollution.
  • Granting consent for establishment (CTE) and consent to operate (CTO) for industries.
  • Enforcing environmental laws and policies in Tamil Nadu.

Functions of TNPCB

  1. Pollution Control: Regulating emissions and effluents from industries.
  2. Monitoring: Conducting regular inspections and audits.
  3. Awareness Programs: Promoting environmental awareness.
  4. Implementation of Policies: Enforcing rules under environmental laws.
  5. Waste Management: Monitoring hazardous, solid, and biomedical waste disposal.

Pollution in Food Establishments

Pollution in food establishments can occur through various means, directly impacting food safety and hygiene. 

Ways Pollution Can Occur:

  1. Air Pollution
    • Sources: Poor ventilation, emissions from machinery, nearby industrial activity, dust, and aerosols.
    • Impact: Contaminates food with dust, fumes, or chemical residues.
  2. Water Pollution
    • Sources: Use of contaminated or untreated water in food preparation, cleaning, or as an ingredient.
    • Impact: Leads to waterborne diseases and microbial contamination.
  3. Soil Pollution
    • Sources: Use of unclean produce or contamination during farming (e.g., pesticides, heavy metals).
    • Impact: Residues or toxins may enter the food chain.
  4. Chemical Pollution
    • Sources: Improper storage of cleaning agents, pest control chemicals, or cross-contact with non-food-grade materials.
    • Impact: Chemical poisoning or chronic health issues.
  5. Physical Pollution
    • Sources: Fragments from packaging, glass, plastic, or tools during food processing.
    • Impact: Injuries or choking hazards.
  6. Microbial Pollution
    • Sources: Inadequate hygiene, improper storage temperatures, or contaminated raw materials.
    • Impact: Bacterial, viral, or fungal contamination of food.
  7. Noise and Light Pollution (Indirect)
    • Sources: High decibel noise or improper lighting can affect worker focus and efficiency.
    • Impact: May increase human error or oversight in hygiene practices.

    • Ecologically Sensitive Areas: 80 µg/m³ (24 hours)
  • Nitrogen Dioxide (NO₂):
    • Industrial, Residential, Rural, and Other Areas: 80 µg/m³ (24 hours)
    • Ecologically Sensitive Areas: 80 µg/m³ (24 hours)
  • Carbon Monoxide (CO):
    • 1-hour limit: 4.0 mg/m³

2. Water Pollution Limits (Effluent Standards for Discharge)

  • pH Levels: 6.5–8.5
  • Biochemical Oxygen Demand (BOD):
    • For inland surface water: ≤30 mg/L
    • For public sewers: ≤350 mg/L
  • Chemical Oxygen Demand (COD): ≤250 mg/L
  • Total Suspended Solids (TSS):
    • For inland surface water: ≤100 mg/L
    • For public sewers: ≤600 mg/L
  • Oil and Grease: ≤10 mg/L

3. Noise Pollution Limits

  • Industrial Area:
    • Daytime (6 AM–10 PM): 75 dB
    • Nighttime (10 PM–6 AM): 70 dB
  • Commercial Area:
    • Daytime: 65 dB
    • Nighttime: 55 dB
  • Residential Area:
    • Daytime: 55 dB
    • Nighttime: 45 dB
  • Silence Zone (e.g., hospitals, schools):
    • Daytime: 50 dB
    • Nighttime: 40 dB

4. Solid Waste Pollution Limits (Solid Waste Management Rules)

  • Composting Waste: <15% inert content.
  • Landfill Waste: >50% inert content for designated sanitary landfills.
  • Hazardous Waste: As per CPCB’s Hazardous Waste Management guidelines.

5. Soil Pollution (Contamination Limits)

  • Heavy Metals (in mg/kg):
    • Lead: ≤50
    • Cadmium: ≤3
    • Chromium: ≤100
    • Zinc: ≤200

6. Emission Limits for Industries (Stack Emissions)

  • Particulate Matter: ≤150 mg/Nm³ (for general industries).
  • Sulfur Dioxide (SO₂): Specific to fuel type; typically ≤800 mg/Nm³ for large boilers.
