Introduction

The Ministry adopted the Policy Statement for Abatement of pollution in view of the increasing trend of pollution in air, water, noise etc. in the country specially in urban areas and which has impaired the quality of life of the citizens. The policy provides several instruments in the form of regulations, legislations, agreements, fiscal incentives and various other preventive strategies for abatement of pollution. The focus of various programmes and schemes of the Ministry and its associated organisations related to pollution, prevention and control has stressed on issues such as promotion of clean and low-waste technology, re-use or recyling, improvement of water quality, natural resource accounting, institutional and human resource development, control of pollution at source rather than the traditional end of the pipe treatment. The significant benefit of this approach is that when waste is reduced/eliminated or solvents are revived and reused; it leads to resource conservation during various industrial processes and minimise the levels of pollutants in the surrounding environment.

The issues pertaining to prevention and control of pollution are dealt with by adopting a multi-pronged approach combining command and control systems, voluntary regulations and economic instruments. Besides, emphasis is also being laid on development of environmental standards, waste minimisation circles, environmental epidemiological studies, preparation of zoning atlas for siting of industries, control of vehicular pollution, noise pollution, promotion of environment education and awareness and natural resource protection, etc. Major activities carried out under several programmes/schemes during the year are as follows:

The scheme for promotion, development and adoption of clean technologies including waste reuse and recyling formulated earlier for small scale industries is being continued. During the year, the following activities have been carried out under the scheme.

Index

Waste Minimisation in Small Scale Industries

A project on Waste Minimisation in Small Scale Industries has been launched with the National Productivity Council as nodal agency under the World Bank assisted Industrial Pollution Prevention Project. About 240 number of industries benefited by participating in the Waste Minimization Circles (WMCs) project under which 60 WMCs have been formed in different sectors in various parts of the country. About 300 Waste Minimisation options were identified by the Member units in these WMCs out of which 120 options have been adopted. These measures resulted in an estimated savings to the tune of Rs. 100 lakhs per annum. The environmental benefits accrued include reduction in water consumption to the extent of 10-35%, reduction in waste generation to the extent of 10-25%, and reduction in raw material consumption to the extent of 10-20%.

An independent review and assessment of the WMC project was undertaken. A strategy based on the conclusions and recommendations of the review consultant’s report was prepared for further improvement of the scheme. A detailed Terms of Reference (TOR) have been prepared based on which and with concurrence of the World Bank, WMC extension programme has been launched through the National Productivity Council as Nodal Agency. The activities undertaken under this programme during the year include:

Ambient Air Quality Monitoring

The Central Pollution Control Board (CPCB) in collaboration with the State Pollution Control Boards (SPCBs) has established a National Ambient Air Quality Monitoring (NAMP) network, comprising 290 stations in 92 cities/towns, under the Air (Prevention and Control of Pollution) Act, 1981 to collect, compile and disseminate information on air quality.

The ambient air quality is monitored by CPCB, SPCBs, Pollution Control Committees, some Universities and Institutes. The data, thus generated, are transmitted to CPCB for scrutinization, analysis, compliation and publication as a consolidated report.

The air quality of different cities/town with respect to three critical pollutants has been compared with the respective National Ambient Air Quality Standards and has been categorized into four broad categories based on an Exceedence Factor (EF) as calculated by the following ratio.

				Observed Annual mean
			concentration of criteria pollutant
Exceedence Factor =	------------------------------------
				Annual standard for the

Trace Metal in Ambient Air of Delhi

Monitoring of lead, cadmium and zinc in the ambient air of Delhi is being carried out since 1992. In January 2000, four more metals-chromium, copper, zinc and nickel-were added to this list. Out of these metals, iron concentration was found high in all types of land use area. Copper and zinc were also present in significant amount but their levels were 3 and 5 times lower than iron. After the introduction of unleaded petrol in Delhi, the level of lead has gone down drastically and are well below the national ambient air quality standards. The presence of cadmium, chromium and nickel was insignificant.

Trend Analysis of Air Pollution in Delhi

A decreasing trend in annual average of SO2 was observed in industrial areas of Delhi. The annual mean concentration of SO2 did not exceed the National Ambient Air Quality Standards (NAAQS) (annual average) during all years of monitoring. Decreasing trend in SO2 levels is observed which might be due to low sulphur diesel introduced in Delhi .

A decreasing trend in NO2 levels is observed which might be due to prohibition from plying of commercial vehicles more than 15 years old in Delhi. A decreasing trend in annual average of NO2 was observed in residential areas of Delhi.

SPM levels exceeded the NAAQS (annual average) during all the years. SPM concentration violated the 24 hourly standard more than 2% of the times during all the years.

High levels of CO are observed in Delhi due to increase in vehicular population especially passenger cars.

The trend in annual of RSPM also shows that annual mean concentration exceeded the NAAQS (annual average) during 1998, 1999 and 2000.

National Water Quality Monitoring Programme

Water quality monitoring was started by the CPCB in 1976 with 18 stations on river Yamuna. The programme was gradually extended and at present, there are 507 monitoring stations in the country spread over all important water bodies. Out of 507 stations, 414 stations are on rivers, 25 on ground water, 38 on lakes and 30 on canals, creeks, drains, ponds etc.

The water quality monitoring results obtained during 2000 indicate that organic and bacterial contamination are continued to be critical pollution in Indian aquatic resources. This is mainly due to discharge of domestic wastewater in untreated form from the urban centers. The municipal corporations have inadequate resources for treating the ever increasing load of municipal sewage. Secondly the receiving water bodies also do not have sufficient water for dilution. Also, the oxygen demand and bacterial pollution is increasing gradually. This situation leads to spread of water borne diseases.

The water quality monitoring results were analyzed with respect to indicator of Oxygen Consuming substances (bio-chemical oxygen demand) and indicator of pathogenic bacteria (total and fecal coliform). The results of such analysis shows that there is gradual degradation in water quality. The number of observations having high BOD and coliform density has increased during this year also as compared to last year.

Taking BOD as indicator of organic pollution, an attempt was made to estimate the riverine length under different levels of pollution as follows :

High pollution 		:	BOD > 6 mg/l
Moderate pollution 	:	BOD=3-6 mg/l
Relatively clean 	:	BOD < 3 mg/l

On the basis of last 10 years water quality monitoring results, the estimated riverine length having different level of pollution is presented below.

Pollution Assessment and Control in Industries

Technology upgradation in existing and new Sulphuric Acid Plants

The environmental problems arising due to sulphuric acid manufacture include

Presently, emission limits for sulphuric acid plants are prescribed as 4.0 kg/tonne of concentrated acid produced and 50 mg/M3 for oxides of sulphur and acid mist. However, due to advancement in process and pollution control technologies it may be possible to further reduce and control the emissions of oxides of sulphur and acid mist. In recent years, number of giant capacity sulphuric acid plants are concentrated in one location . For example, two streams of 3500 MT/day each and two streams of 1000 MT/day each have been set up at Paradeep. This situation dictates minimisation of emissions from each of these plants.

With the above background, a project has been initiated to study the technology upgradation in existing sulphuric acid plants and state-of-art technology in new plants so as to reduce and control oxides of sulphur and acid mist emissions.

Pollution Potential of Mines

To assess the pollution potential of chromite mines in the Sukinda Valley in Orissa and coal mines in Talcher area of Orissa, detailed survey and environmental monitoring were conducted by the Central Pollution Control Board Eastern Zone office. It was observed at the chromite mines that enormous volume of water containing chromium in hexavalent form was being discharged into adjacent water bodies. The overburden was being dumped near the queries, as a result soluble metals may percolates to the groundwater. The treatment facilities are very limited.

Talcher area of Orissa has many coal mines and most of them are open-cast. Due to accumulation of coal near the mines, frequent fires were observed. Effluent generated from most of the workshops were being treated before discharging into the surface waters. Surface mining in Lingaraj open cast mine was an environment friendly method of primary rock excavation.

Coal Washeries

Four coal washeries were extensively studied to ascertain the effectiveness of common coal washing processes. The products of coal washeries, i.e. washed coal, middling coal and reject coal were quantified to assess the quantity of fine coal being discharged with the effluent. The emphasis was on the quality of raw coal and the process of coal washing to highlight the in-plant pollution control measures because more the coal is recovered less being the pollution. The treatment efficiency of the settling tank was evaluated to justify the claim of zero discharge. Though adequate settling tanks are available for treating the effluent, but their maintenance is not proper. During dry season, it is possible to contain the effluent, but during wet season it is difficult. It cannot be ruled out that during rainy season, surface runoff may carry huge quantities of fine coal, which ultimately join the river Damodar. It is recommended to increase the rate of settling with due attention to maintain the settling tank.

Flyash Management in Thermal Power Plants of West Bengal

Eleven thermal power plants (TTPs) of West Bengal, each having capacity exceeding 100 MW were studied for the status of pollution control, fly ash management and performance of air pollution control equipments.

The observations of the study are as follows :

Bio-Medical Waste Management

Implementation of Bio-medical Rules in Kolkata

The Central Pollution Control Board carried out bio-medical waste management study in nine hospitals in Kolkata having bed capacity more than 500. During the study it was observed that there was barely any biomedical waste segregation as per the Biomedical Waste Rules. No pre-treatment is given to the wastes.

The study reveals that the average waste generation/bed is 250 gram/day, therefore having a bed capacity of 5450, the city of Allahabad generates 1.3 MT/day of biomedical waste, which deserves segregation followed by prescribed treatment and safe disposal.

Recently, Allahabad Nagar Nigam has allotted a land to Allahabad Nursing Home Association for installation of Common Treatment Facilities for small nursing homes. Allahabad Nursing Home Association is in process to contract the management and handling of biomedical waste to private party.

Inventorisation of Hazardous Waste

The Central Pollution Control Board had taken up studies on inventorisation of hazardous waste generation in various States, with a view to identify hazardous waste generating units, quantification of hazardous waste generated and present practices adopted for hazardous waste management by various industrial sectors. During the year, studies in the States of West Bengal, Tamil Nadu and Union Territory of Chandigarh, Pondicherry, Daman, Diu & Dadra Nagar Haveli, have been completed.

Criteria for Hazardous Waste Disposal to Landfill and Management of Leachate

The hazardous wastes generated by the industries are required to be disposed in secure landfill. The landfill sites generate leachate. If leachate is not collected and treated properly, it may contaminate groundwater resources. In view of the hazard characteristics of leachate, CPCB has taken up a project on "Development of Standards for Leachate from Hazardous Waste Disposal Site". The project has been completed and the draft report has been prepared containing identification of hazardous waste suitable for land disposal, guidelines for leachate collection and removal system, criteria for disposal of hazardous waste into secure landfill and suggested treatment options for treatment of leachate generated form hazardous waste landfill site and environmental standards for leachate.
