Functions of CPCB comes under both national level and as State Boards for the Union Territories. CPCB, under the Water (Prevention and Control of Pollution) Act, 1974, and the Air (Prevention and Control of Pollution) Act, 1981, aims to promote cleanliness of streams and wells in different areas of the States by prevention, control and abatement of water pollution, and to improve the quality of air and to prevent, control or abate air pollution in the country. •
Air quality/ pollution: CPCB runs nationwide programs of ambient air quality monitoring known as
National Air Quality Monitoring Programme (NAMP). The network consists of 621 operating stations covering 262 cities/towns in 29 states and 5 Union Territories of the country. Under N.A.M.P., four air pollutants viz.,
Sulphur Dioxide (SO2),
Oxides of Nitrogen as NO2,
Suspended Particulate Matter (SPM) and
Respirable Suspended Particulate Matter (RSPM/ PM10) have been identified for regular monitoring at all the locations. The monitoring of meteorological parameters such as wind speed and wind direction, relative
humidity (RH) and
temperature were also integrated with the monitoring of air quality. This information on Air Quality at ITO is updated every week. •
Water quality/ pollution: Fresh water is a finite resource essential for use in agriculture, industry, propagation of wildlife & fisheries and for human existence. India is a riverine country. It has 14 major rivers, 44 medium rivers and 55 minor rivers besides numerous lakes, ponds and wells which are used as primary source of drinking water even without treatment. Most of the rivers being fed by monsoon rains, which is limited to only three months of the year, run dry throughout the rest of the year often carrying wastewater discharges from industries or cities or towns endangering the quality of our scarce water resources. CPCB in collaboration with concerned SPCBs/PCCs established a nationwide network of water quality monitoring, which has running 1019 stations in 27 States and 6 Union Territories. The monitoring process is done on quarterly basis in surface waters and on half yearly basis in case of ground water. It covers 200 Rivers, 60 Lakes, 5 Tanks, 3 Ponds, 3 Creeks, 13 Canals, 17 Drains and 321 Wells. Among the 1019 stations, 592 are on rivers, 65 on lakes, 17 on drains, 13 on canals, 5 on tanks, 3 on creeks, 3 on ponds and 321 are groundwater stations. The inland water quality monitoring network is operating under a three-tier program i.e.
Global Environment Monitoring System (GEMS),
Monitoring of Indian National Aquatic Resources System (MINARS) and
Yamuna Action Plan (YAP). •
Urban area programs (EcoCity Program): CPCB programs for urban areas, also known as
EcoCity Program comes under X Plan to improve environment through implementation of identified environmental improvement projects in the selected towns and cities. Pilot studies conducted for urban areas by the
Centre for Spatial Environmental Planning created at the CPCB under the
World Bank funded
Environmental Management Capacity Building Project and supported by the
GTZ-CPCB Project under the
Indo-German Bilateral Program. According to these studies CPCB develop a comprehensive urban improvement system employing practical, innovative and non-conventional solutions. Under the X Plan, a budget provision of Rs. 15 crore has been made for the period 2002–03 to 2006-07 for the Ecocity projects. •
Municipal Solid Waste rules: Every municipal authority comes under the
Municipal
Solid
Wastes (Management & Handling) Rules, 2000 (MSW rules, 2000) and responsible for collection, segregation, storage, transportation, processing and disposal of municipal solid. CPCB collects necessary information form municipal authorities and provide them technical assistance. •
Noise Pollution/ Rules: According to
S.O. 123(E) by MoEFC, various sources like industrial activity, construction activity, generator sets, loud speakers, public address systems, music systems, vehicular horns and other mechanical devices have deleterious effects on human health. CPCB has the responsibility to regulate and control noise producing and generating sources with the objective of maintaining the ambient air quality standards. •
Environmental Data Statistics: CPCB manages environmental data statistic in which
air quality data and
water quality data comes through. In the case of air quality data, it measures the level of
SO2,
NO2,
RSPM and
SPM. CPCB measure and maintains water quality data as well. Quality level of river and ponds are the major fields which comes under the water quality data criteria.
Comprehensive Environment Pollution Index The
Comprehensive Environmental Pollution Index (CEPI) is the CPCB's pollution score in
industrial areas, assessing air, water, and land quality using a 0-100 scale; scores ≥70 mean Critically Polluted Areas(CPAs), prompting action plans, serving as an early warning for environmental management. ==Organisational structure==
