Chapter XII Environment
Chapter XII Environment is a Chennai metropolitan master plan chapter issued by the Chennai Metropolitan Development Authority that describes environmental conditions, pollution sources, monitoring and flood mitigation in Chennai. It records Tamil Nadu Pollution Control Board findings and national ambient air quality standards, but the supplied text does not state an order number, publication date or property specific restriction.
What the chapter covers
Chapter XII Environment treats the metropolitan environment as two connected parts. Natural features and resources include air, noise, water, land, open spaces and forests. The habitat includes the built environment and infrastructure such as water supply, sewerage and solid waste disposal.
The chapter says urban development should be balanced with environmental opportunities and constraints. It mainly presents environmental data and observations rather than announcing a change in land use or imposing a property specific requirement.
Who may be affected
Chapter XII Environment is relevant to property buyers, owners, planners, industries and professionals assessing environmental conditions in Chennai. It identifies areas affected by air pollution, describes polluted waterways and records major sources of sewage and industrial discharge. The supplied text does not specify approval procedures, fees or individual obligations for property owners.
Air pollution findings
The Tamil Nadu Pollution Control Board monitors Chennai through its own ambient air quality programme and the National Ambient Air Quality Monitoring Programme.
Key findings include:
- Vehicle emissions are identified as the largest source of air pollution in Chennai.
- The vehicular sector accounts for 71.28 per cent of the calculated pollution load, followed by the industrial sector.
- Dust also rises from untidy roads and sand gathered along roadsides.
- High impact locations include T. Nagar, parts of Saidapet and Adyar, Choolaimedu, Vadapalani, Royapettah, Egmore, Tenampet, parts of Tondiarpet, Koyambedu, Purasawalkam, Mandaveli, Mylapore and George Town.
- Korattur, Anna Nagar and Velachery are classified as medium impact areas. Other areas are classified as low impact.
The chapter reproduces national ambient air quality standards for industrial, residential and sensitive areas, covering sulphur dioxide, oxides of nitrogen, suspended particulate matter, respirable particulate matter, lead and carbon monoxide.
Water pollution and drainage
The Tamil Nadu Pollution Control Board found that the Buckingham Canal, Otteri Nullah, Adyar River and Cooum River were polluted and unsuitable for listed uses including drinking, bathing, fisheries, industrial use, cooking, washing and agriculture. Contamination was relatively highest in the Buckingham Canal, followed by Otteri Nullah and the Cooum River.
The chapter also records wastewater outfalls from industries, commercial institutions, sewage treatment plants, pumping stations, drain overflows and slum settlements. It notes that some industries had plugged outfalls, installed effluent treatment plants and reused treated effluent within their premises.
A flood alleviation project sanctioned by the Government of Tamil Nadu with an outlay of Rs.300 crores covered macro and micro drainage improvements in the Chennai Metropolitan Area.
