6 1.0 INTRODUCTION Human environment can be defined as the interaction of the surroundings in which he lives. Thus, the air he breathes, the water he drinks, the temperature in which he survives and in fact all other items which have a direct bearing on human existence can be classified as environment. Usually the most important and universally accepted components of this complex system are the land, which gives him food, the water bodies which satisfy his thirst and the atmosphere which provides him air to breath. Any imbalance in any of these has a direct detrimental effect on the physical and mental health of man. Today one hears of contamination of the atmosphere due to nuclear mishaps, pollution of land due to nuclear fallout and fouling natural waters by indiscriminate waste discharge by industries. The rapid deterioration of environment has not only jolted the developed and developing countries in action, but sounded a clear warning bell for the underdeveloped countries as well. The message is clear Either preserve the environment and prosper or pollute it and perish. Earlier, the assessment of the projects was done on Technical feasibility reports and Cost-Benefit-Ratio which mainly considered financial & technical resources. But no consideration was given to the environment protection in this evaluation and these flaws became apparent with continuous deterioration of environment. Thus in order to have more realistic evaluation, and keeping in view the deteriorating conditions, another dimension was added which is now called as Environmental Impact Assessment (E.I.A.). This forms an integral part of the project and is taken into account while appraising the project at different stages. Thus in the new comprehensive approach all considerations like, Technical, Financial & Environmental are given due weightage. 6

7 M/S HIMALAYA ALKALIES & CHEMICALS LTD (Formerly SNJ Chemex (P) Limited) have its corporate office at 314, PP Tower, Netaji Subhash Place, Pitampura, New Delhi, is formed to setup its new unit in Himachal Pradesh. The promoters with its group companies are engaged in the area of manufacturing and marketing of chemicals. The company started some 25 years back with the manufacturing of CPW and gradually developed to become the leading company for the production of CPW in the country. Their group is one of the biggest consumers of chlorine in its manufacturing facilities at various locations at Haryana, Punjab & West Bengal. To keep pace with growth of the company, the management has planned to further diversify the business into manufacturing of basic chemicals i.e. Caustic soda. This will not only reduce their dependency on other suppliers of Chlorine but it will also help to consolidate its production centres at one place. The company proposes to set up 400 MT per day capacity plant The plant will be located in village Johran, Kala Amb, Tehsil Nahan in Dist. Sirmaur in the state of Himanchal Pradesh. The availability of uninterrupted power supply at competitive rate comparatively with its neighboring states to make an edge over other manufacturers in the northern India.

9 3.0 BASELINE ENVIRONMENTAL SETTING 3.1 The State Himachal Pradesh having world s mightiest mountain ranges is one of the hilly States situated in the Northern part of India. It is blessed with some of the most spectacular and beautiful landscapes. It came into being in November, 1966 after the re-organization of States. Earlier, it was part of the combined State of Punjab. The various hill towns in the State not only provide visitors reprieve from the sultring heat of the planes, but offer beautiful scenic sites which are real treat to the eyes. Kulu and Kangra valleys offer natural beauty which is no less than Kashmir Valley. Valleys and streams, snow clad mountains and temperate forests offer tourists and sportsmen all they want. The total area of the State is about 55,700 sq. km., with a population of more than 60lac. The literacy rate is about 63%. The main fruits / crops in the State are apple, plum, ginger, peach, potato, forest produce, rice and wheat. The State has good deposits of minerals like gypsum, lime stone and slate etc. Earlier the economy of the State mostly depended on tourism and a large number of tourist sites had been developed by the State. However, after the re-organization, the State has made big strides in the field of industrialization also. Industries like Cement, Electronics, Fertilizers, Pharmaceuticals and Liquor can be found in good number at different places in the State. Hydel Power in the State has given a big boost to the Industries. A number of Industrial areas have been developed in the State, where all facilities are provided to the entrepreneurs. Parwanoo, Barotiwala, Baddi, Paonta Sahib and Raja Ka Bag are some of the important industrial areas developed by the State in the last two decades. 9

22 4.5 Manufacturing Process Caustic soda manufacturing process improved significantly due to upgradation of technology from Diaphragm technology to the latest state of the art technology ie the Membrane cell technology. The technology is an Environmental friendly and fuel efficient. Power is the main raw material used for the production of caustic, which alone cost 60% of the cost of production, this technology save 35% energy than the earlier process. The following schematic diagram shows the difference in the technologies. PROCESS FLOW CHART 22

23 MEMBRANE CELL TECHNOLOGY: The most common chlor-alkali process involves the electrolysis of aqueous sodium chloride (a brine) in a membrane cell. In the membrane cell, the anode and cathode are separated by an ionpermeable membrane. Saturated brine is fed to the compartment with the anode (the anolyte). A DC current is passed through the cell and the NaCl splits into its constituent components. The membrane passes Na + ions to the cathode compartment (catholyte), where it forms sodium hydroxide in solution. The membrane allows only positive ions to pass through to prevent the chlorine from mixing with the sodium hydroxide. The chloride ions are oxidised to chlorine gas at the anode, which is collected, purified and stored. Hydrogen gas and hydroxide ions are formed at the cathode. 23

24 4.6 Facilities at the Plant The firm has 1, 50,000 sqm of land where factory building, boundary wall and some other ancillary structures are proposed to be constructed. It provides adequate space for the following areas of working:- 1. Storage for raw material and finished goods. 2. Plant and Machinery 3. Storage 4. Offices 5. Toilets 6. Water storage tanks Open space will be landscaped and trees will be planted in due course of time. 4.7 Power The requirement of Power for the unit is 42 MW which will be supplied by HPSPCL. 4.8 Water Supply The water requirement of the unit will be met from own tube-well. The daily requirement of water is about 2950 m 3. About 2760 m 3 water will be required in the process and make up water required for cooling purpose will be 50 KLD. For domestic purpose 20 KLD and 120 m 3 water required for boiler. The capacity of storage tank for cooling purpose is about m 3. Another tank of about 100 m 3 has also been provided for fire fighting which shall be kept always full.

26 4.10 Waste Handling Liquid waste Liquid waste: is treated for ph control and collected in a tank. The water is thus passed through the RO plant to control its TDS contents and brought it down below 100ppm and will be recycle back into the plant. Part of this water will be utilized in gardening and other part of the factory. The effluent treatment plant is designed such that there will not be any liquid discharge from the factory Solid waste About 4% solid waste will be generated from the process. The solid waste is non hazardous. It will be sent to filling low lying area or as per norms of State Pollution Control Board Hazardous waste The industry will install two no. DG sets of 500KVA capacity each. The Hazardous wastes generated from the unit, such as used oil from DG Set shall be sold to recyclers. There are no other hazardous wastes Pollution Control Measures The main sources of pollution from the unit are discussed as under: Air Pollution Emergency Chlorine Scrubber (ECS) System The emergency chlorine scrubber (ECS) uses extraction fans to collect gas from all the chlorine-containing plant vents. The gas is then scrubbed with caustic soda to remove chlorine producing sodium hypochlorite. The reaction is as follows: 26

27 The ECS is a safety critical system designed to accommodate chlorine surges during plant upsets for 10 minutes minimum of full chlorine production. All vents containing chlorine pass to the ECS system. The concentration of chlorine in the exit gas from the ECS is monitored and alarmed. Electrical power to the circulation pumps and extraction fans is backed up by emergency power from a stand-by emergency diesel generator. A nitrogen ejector that does not require power for operation further backs up the fans. A caustic gravity head tank that does not require power for its operation, further backs up the caustic pumps. Hypo Tower: The gases come out of the hypo tower and HCl plant. Well designed scrubbers keeps the vents prevents any hazardous gases escaping into the atmosphere. Chlorine and HCl vapors concentration s are kept below the permissible limit ie 5 ppm. Similarly the boiler chimney is designed to prevent the to be in compliance of pollution norms. Installation Of Chlorine Sensing Alarm System: Chlorine alarm system which will sense above 3 mg/nm 3 in air will be installed in CP complex for early warning on action of chlorine control will be received. Neutralization System: Industry will install a neutralization system where in un-reacted chlorine gas will be sucked from 08 Nos CP reactors through pressure regulated valve and neutralized with caustic soda to from sodium hypo-chloride. Initially chlorine will be supplied in toners but at later it is to be supplied through pipeline. Boiler: Industry will install steam boiler of 14TPH capacity. The wood briquette/pet coke will use as fuel for boiler. APCD cyclone fallowed by wet scrubber will be installing with boiler to control emission. 27

28 Water Pollution There will be no generation of waste water from process. The waste water generation from domestic, cooling and boiler blow down shall be used for plantation after treatment Noise Pollution There is no noise producing machineries in the unit. All machines are spread at different places within the covered sheds. Thus no noise of significant level shall go out side the working area which may disturb the general noise environment. DG set installed shall be noise free & with canopy. 28

29 5.0 ENVIRONMENT IMPACT ASSESSMENT: 5.1 Present Environment: Various Environment factors as existing in the project area which possibly could be affected by the activities have been assessed & identified as below: (i) Ambient Air (ii) Water Quality (iii) Noise (iv) Land use pattern (v) Soil and Agricultural (vi) Demography and socio-economic pattern. 5.2 Probable Impact on Environment: The above factors will be checked after the implementation of the project to cross check the probable impact discussed hereunder and remedial measures taken wherever necessary. Broadly the impacts may be classified in two categories as under:- i) Short term - during construction/development stage ii) Long term - during operational stage. Both these categories have been considered while predicting and evaluating the impacts as given herein after:- 5.3 DEVELOPMENT STAGE: - (SHORT TERM) This is a construction phase of the project and the impacts are temporary due to construction related activities which are as under:- i) Air Environment: There is no point source of air pollution. The only source will be due to construction and plying of vehicles within unit. Some 29

30 emission may be expected from vehicles plying in the area for transportation of material etc. Kerosene oil shall be provided to the labour so that they do not burn wood for cooking etc. ii) Water Environment : Requirement of water during construction & machinery foundations will be about 1.0 m 3 /day and there will be no waste discharge as the same will be used completely. However, during monsoon some malba etc may get washed due to run off from the site. There is a natural nallah near the land which takes the entire run off from the area. Labour during construction is not very large. Hardly about 50 persons may be working daily on an average who may be using water for drinking and bathing etc. Toilet facilities with septic tank will be provided to 1 toilet for 20 persons who will be used by the labour. In view of this there is no likelihood of any significant impact on the general environment of water in the area. iii) iv) Noise Environment: Some noise may be expected from the working of the machinery repair purposes and movement of vehicles. Steps will be taken to reduce its effect by resorting to staggering of various operations. Even otherwise since there will not be any large scale machinery, the activity is not likely to have any significant effect on the over all noise environment. Land Environment: The total land area of the project is 1, 50,000 sqm. Natural drainage will not be disturbed. Solid waste from construction activities will be used within the premises under roads & 30

31 refilling. There will not be any significant impact on land in general. v) Socio Economic: The project does not involve any displacement of population or rehabilitation of any kind. Rather it will provide employment to local people in the shape of additional man power required for the units, & will and boost the economy of the area. It will have some positive impact, although not to a large extent. 5.4 OPERATIONAL STAGE: - (LONG TERM) After completion, when the unit starts production, the operational impacts on the various parameters are considered as under:- i) Ambient Air Environment: There is only one source of likely pollution which is vapours of Acid/alkali mist from the manufacturing process. All the processes are closed circuits as such emissions to the open atmosphere will be minimum, however, APCD, Alkali Scrubber will be provided at the exit point to neutralize the acid mist. ii) Water Environment: Alkaline Effluent System: Effluent from alkaline process area catchments drains to trenches which channel effluent to the alkaline effluent sump. From here, alkaline effluent is transferred to the alkaline effluent tank where it is mixed and neutralized using HCl and NaOH to achieve a ph in the range of 6.5 and As these neutralization reactions have the potential to liberate chlorine gas under certain conditions, the alkaline effluent tank is operated under light suction, venting to the emergency chlorine scrubber (ECS) where any chlorine gas present is removed. 31

32 Acidic Effluent System: The acid effluent system is quite similar to the alkaline effluent system discussed above. Effluent from acid process areas drains to the acid effluent trench, then to the acid effluent pit from where it is pumped to the acid effluent tank. The acid effluent tank is used to mix and neutralize effluent using HCl and NaOH to achieve a ph in the range of 6.5 and Rainfall data shows that the area is having adequate rainfall. The guidelines for Rain Water Harvesting and Artificial Recharge of Ground Water issued by the Central Ground Water Authority will be followed. iii) Land Environment: The Project is coming in the agriculture land. Thus there will not be any significant adverse effect on the existing general land environment with the coming up of the project. iv) Noise Environment: There will be no noise producing machinery or equipment except DG Set which will be placed in acoustic room, causing least disturbance in the area. There is no likelihood of any significant change in noise environment. v) Socio Economic Pattern The project will provide employment to local people in the field of running plants and maintenance of machinery, APCD & security etc. Thus it will have positive effect on the employment potential in the area. 32

33 6.0 ENVIRONMENTAL MANAGEMENT PLAN: 6.1 General Environment Management Plan (E.M.P) in a project is prepared to mitigate the possible adverse effect of various activities on the existing environmental factors, during construction as well as in operational stages, to avoid their deterioration, if any. It is desirable that necessary steps are taken right from the beginning of the project to be more effective. As a social and moral obligation on the part of every body it becomes our bounden duty to leave our environment to the next generation in a state at least what we inherited from our ancestors, if not in a better condition. E.M.P. for this project has been prepared keeping in view the existing conditions and likely changes which may occur due to the proposed project. The implementation and monitoring of different control measures have also been covered. These are discussed as under:- 6.2 Air Environment During construction stage water will be sprinkled on the soil to avoid dust generation, if any. The debris and unused construction malba shall be removed immediately for recycling, if any, or for land fill. All vehicles for service activities at the project site shall be checked for vehicular emission. The agencies will be asked to keep them within prescribed limits. They will also be asked to maintain them properly. During operation phase alkali scrubber shall be provided to neutralize acid mist from process, to keep it within permissible limits. Cyclone will be provided with boiler to mitigate air environment. Tree plantation shall be resorted to for further improving the air environment in general and minimize noise levels, if any. 33

34 6.3 Water Environment: Source of water will be own tube-well. During construction toilet facilities shall be provided to labour with septic tank. Finally, waste water from the toilets shall be taken to septic tank through underground delivery system. It will not be thrown outside either on land or in any water body. Roof top rain water shall be harvested and used for ground water recharge to minimize effect of withdrawal of water from the underground. 6.4 Land Environment: To avoid erosion of the top soil the development is planned in the shortest possible time and land-clearing activity shall be kept to the absolute minimum by working at the specific sites one by one where construction is to take place so as to increase detention and infiltration. Natural waterways/drainage pattern shall be maintained by providing culverts where needed. The requirements of sand and aggregates for the construction works will be met through venders. The land use is thus so planned that there is minimum adverse impact. 6.5 Solid Waste The solid waste generated from the construction activities shall be effectively recycled within the project. The solid waste generation from the process the process will non toxic/non hazardous. The disposal of solid waste will be as per norms of State Pollution control Board. 6.6 Noise Environment During Construction stage NO HORN signs will be displayed at prominent places. The drivers shall be directed not to blow horn unnecessarily. Vehicle owners will be asked to maintain them in proper condition. During operational stage noise creating machinery such as 34

35 blower, ID Fans etc will be housed different places within closed sheds so as not to disturb the noise level in the area. The DG set shall be noise free. 6.7 Green Belt: The main objective of the green belt is to provide a barrier between the source of pollution and the surrounding areas. The green belt helps to capture the fugitive emission and to attenuate the noise generated, apart from improving the aesthetics. Development of green belt and other forms of greenery shall also prevent soil erosion and washing away of topsoil besides helping in stabilizing the functional ecosystem and further, to make the climate more conducive and to restore water balance. It is planned that the selected plants will be grown as per normal horticultural (or forestry) practice and authorities responsible for plantation will also make sure that adequate provision for watering and protection of the saplings exists at site. Species of trees shall be selected in consultation with the forest Department officers. In all about 500 trees & shrubs are proposed to be planted within the unit premises. 35
