POWER PLANT AT VILLAGE NAYA NANGAL, DIST. RUPNAGAR, PUNJAB INTRODUCTION


2 INTRODUCTION

2.1.1 Identification of Project Proponent & Project

2.1.2 Project Proponent

Punjab Alkalies and Chemicals Limited (PACL) was incorporated as a Public Limited Company on December 1975

under the name “Punjab Alkalies Limited”. The name of the Company was subsequently changed to Punjab Alkalies

& Chemicals Limited and a “Fresh Certificate of Incorporation Consequent on Change of Name” dated 19th April

1983 was obtained from the Registrar of Companies, Punjab, HP & Chandigarh, Jalandhar. The Company is

promoted by the Punjab State Industrial Development Corporation Limited (PSIDC), a wholly owned Punjab

Government Company.

Total capacity at site is 99,000 MTPA of caustic soda. This entire capacity was established in stages, between the

years 1984 to 1998 and did not entail securing Environmental Clearance based on regulations in place during that

time. PACL had received a letter from MoEF regarding non-requirement of EC for expansion of Chlor-Alkali plant

from 73,730 MTPA to 99,000 MTPA due to no additional pollution load certificate given by Punjab State Pollution

Control Board. Copy of the same is attached as Annexure 1.

The company is managed by a Board of Directors comprising of senior Government officers, professionals and

experienced persons as per Table 2-1 below:

2.3 Need for the Project and its Importance to the Country & Region

2.3.1 Chlor-Alkali Plant

Based on the current market scenario of Caustic soda, the existing production is required to be increased from

99,000 MTPA (300 MTPD) to 2,64,000 MTPA (800 TPD) and also due to the availability of infrastructure at the

existing facility the need for the proposed expansion of the project is decided to be carried out.

The size of the Indian Chlor-Alkali sector at 4.1 million tonnes1 (~5% of world market). The Chlor-Alkali industry is

the oldest and largest segment of the inorganic chemical industry. It comprises of caustic soda, liquid chlorine and

soda ash.

Caustic soda is used in various applications such as finishing operations in textiles, manufacture of soaps and

detergents, alumina, paper and pulp, control of pH (softening) of water, general cleansing and bleaching. The

aluminium industry is the biggest demand driver for caustic soda.

Chlorine is used in multiple sectors such as manufacture of polymers like PVC, bleaching applications, paper and

pulp and textile industry. Alumina processing is expected to drive the caustic soda demand in the country. Textile

and chemical sectors are expected to further push the caustic soda demand in India.

Indian Chlor Alkali industry is driven by caustic soda demand which stood at ~7 million metric tonnes in FY 20172.

This project aims to satisfy pending Caustic Soda demand in the Country and will help in import substitution to a

great extent.

2.3.2 Stable Bleaching Powder

As a chlorine derivative, stable bleaching powder is proposed to cater the market requirement which includes water

treatment plants, paper industries of North India. It is used as a strong oxidising, bleaching and disinfecting agent.

2.3.3 Hydrogen Peroxide

There are only four major manufacturers in India namely, Gujarat Alkalies and Chemicals Ltd., National Peroxide,

Asian Peroxide, Hindustan organic Chemicals Ltd.

Based on data of FY 2014-15, the total production is 96,172 MTPA against the demand of 1,19,800 MTPA. There is

a huge gap of 23,268 MTPA between supply and demand.

Hence the proposed project will cater the need of Hydrogen Peroxide demand in the market.

2.3.4 Captive Power Plant

Power is one of the main input for the production of Caustic Soda and it constitute about 70% of cost of

production. At present the power requirement of PACL is about 40 MW and is being received from PSPCL Grid. After

expansion the total Power requirement will increase to 75 MW. To counter the ever increase of power cost, PACL

has decided to set up its own Captive Power Plant of 75 MW capacity in phased manner.

2.4 Demand & Supply Gap

The chlor-alkali industry mainly consists of the production of two key products – caustic soda and chlorine.

Together, the alkali chemicals comprised 70% of the total chemicals production in FY17. According to Alkali

Manufacturers’ Association of India (AMAI), the Indian Chlor-alkali market was estimated at around USD 1.9 billion

-------------------------------------------------------------------

PACL





in FY 2010, vis-à-vis global market size of USD 48 billion. Caustic soda and chlorine are produced together in the

ratio of 1:0.89 (also known as Electrochemical Unit or ECU) through electrolysis of salt. On account of their co-

production, the market dynamics for caustic soda and chlorine are heavily influenced by each other. Internationally,

it is chlorine based, whereas, in India, it is influenced by caustic soda.

Caustic soda finds its application mainly in alumina, textiles, paper, organics, inorganics, soaps & detergents, etc.

The segment has grown at an estimated Compounded Annual Growth Rate (CAGR) of ~6%.

2.5 Export Possibility

2.5.1 Domestic / Export Market

The finished products are conforming to Indian Standard /as per the customer requirement. The customers are

located in the plant’s vicinity. Some customers are located outside Punjab also, but mainly in northern India only.

Sale is made to direct customers and through traders.

Export of the products is not envisaged.

2.6 Employment Generation (Direct & Indirect) due to the project

The existing manpower deployed at PACL’s Naya Nangal site is 400 persons direct and about 500 indirect. The

existing manpower will be sufficient to operate the plants after expansion in Caustic Soda Plant. However, 200

person will be required for operating Power Plant. Local skilled and semi-skilled workers will be preferentially hired

for the purpose.

The positive impact includes enhanced direct employment for technical / administrative works and indirect

employment opportunities for transporters of raw material like salt, coal etc. and finished goods.

3.5 Project Description with Process Details

3.5.1 Chlor Alkali Plant (Existing + Expansion) – 800 TPD along with New Flaker Plant – 200 TPD

The process is based on Membrane Cell technology. The main steps in the process to manufacture caustic soda

are:

Purification of brine.

Electrolysis.

Concentration and flaking of caustic soda solution.

In the process Hydrogen and Chlorine gas are produced as the co-product.

PACL





Brine Purification

General

Brine for ion exchange membrane Chlor-Alkali process is prepared by dissolving salt in the return brine from the

electrolysis plant, and purified in two stages. Primary purification removes impurities like calcium, magnesium,

sulphate, iron, silica etc. to ppm level.

Secondary purification is required to make brine suitable for the ion exchange membrane Chlor-alkali process.

Primary Brine Purification

Primary Brine Purification section consists of Salt Handling system, Brine Saturator, Reactor Clarifier, Clarified Brine

Tank and associated facilities.

This process includes Brine saturation, chemicals dosage, reaction and sedimentation. The purpose of this process

is to re-saturate the return brine with raw salt and to remove impurities from the saturated raw brine.

The return brine is fed from the top of the Brine Saturator and saturated with salt. The salt is continuously supplied

to the top of the saturator by a Belt Conveyor System.

The saturated raw brine overflows from the Brine Saturator and flows into Reactor. Chemicals such as barium

carbonate, sodium carbonate, caustic soda are fed to Reactor.

Calcium, magnesium and other multivalent cations and sulphate anions in the raw brine react with these chemicals

reacts & flocks are settled & drained while the brine is held in the reactor.

pH of the brine is controlled by the addition of caustic-soda to the brine. Then the brine overflows from the reactor

into the Brine Clarifier. Flocculent is fed to the brine line entering the clarifier.

Suspended solids in the brine are removed by settling in the Clarifier provided with water seal & insulated from the

sides. The brine, thus clarified, flows into clarified Brine Tank over the weir of Clarifier & is pumped out and

recirculated to the brine system before Reactor for better clarification. Slurry is periodically measured for better

control.

A part of slurry is sent to Sludge Filter System. The clarified brine is sent to Secondary Brine purification section by

clarified brine pump.

Secondary Brine Purification

Secondary Brine Purification Section consists of Brine Filter and Ion Exchange Resin Column.

The clarified brine is filtered through the filter and flows into filtered Brine tank. Suspended solids caught on the

filter element surface are blown down to Filter Slurry Pit. Filter Slurry in the pit is sent to centrifuge where most of

the brine is recovered and fed back to Return Brine Tank.

Ion Exchange Resin Column packed with special Ion Exchange resin is operated and controlled automatically from

control room.

This specially developed Ion exchange resin can remove multivalent cations harmful to the Ion exchange

membrane. The brine thus purified is fed to Electrolyser and electrolysis is conducted.

Electrolysis

Electrolysis section consists of bipolar Electrolysers and their associated equipment.

PACL





Electrolyser

Electrolyser consists of number of bipolar type cell frames with the metal anode and the activated cathode, the

Ion exchange membrane, press unit for mounting cell frames, sub-headers for feeding anolyte and catholyte, sub-

headers, and oil pressure unit which supplies oil to oil cylinders.

Cell frames holding the Ion Exchange membrane in between are fixed by the oil cylinder installed at the end of the

press unit. This structure ensures no leakage of electrolytes because uniform pressure can be applied to gasket

surface and cell frame of metal structure ensures no electrolyte leakage caused by deformation even after a long

period of operation.

Anolyte Circulation

Anolyte circulation system is composed of Anolyte Circulation Tank and anolyte circulation pump. Anolyte is fed into

each of anode compartment of cell frames through sub-headers and hoses, and recirculated to Anolyte circulation

Tank. Purified brine is fed to maintain anolyte concentration within a designed level. A part of the anolyte, is taken

out from Anolyte Circulation Tank to Depleted Brine Tank by overflow.

Anolyte Circulation system is designed to ensure steady and uniform distribution of anolyte to each cell and to

cope-up with any change in electrolysis conditions such as production rate change.

The diluted brine collected in Depleted Brine Tank is sent to De-chlorination Tower for removal of Chlorine gas.

Chlorine gas generated in electrolyser is separated in Anolyte Circulation Tank and sent to Chlorine gas cooling,

drying and compression section.

Catholyte Circulation

Catholyte Circulation System is composed of Catholyte Circulation Tank, Catholyte Circulation Pump and Catholyte

Cooler.

Catholyte is circulated through cathode compartment of cell frames to Catholyte Circulation Tank by Catholyte

Circulation Pump, and a part of it is taken out from Catholyte Circulation Tank to Caustic Soda Tank and sent out to

caustic evaporation section. To keep the concentration of caustic soda at designed level, demineralised water is fed

to catholyte inlet sub-header. Hydrogen gas generated in Electrolyser is separated from the catholyte in catholyte

Circulation Tank and sent to Hydrogen Gas Cooling and Compression Section. Heat generated in electrolyser is

removed by cooling water in Catholyte Cooler.

De-Chlorination of Return Brine

De-chlorination section is composed of a Vacuum Tank, Vacuum Pumps, cooler and associated facilities. Return

brine (depleted brine) from Electrolysis Section free of chlorine is sent for saturation.

From the vacuum tank chlorine gas is sucked by the vacuum pump through a water cooled cooler and is then

introduced to chlorine gas product main line.

The depleted brine, de-chlorinated through vacuum tank still contains small amount of free chlorine which can

cause damage to the filter elements in Brine Filters and damage ion exchange resin in Ion Exchange Resin

Columns. Sodium Bisulphite is added to kill free chlorine. Return brine is then fed to Return Brine Tank & pumped

to salt saturator.

Caustic Concentration

The caustic soda concentration system consists of triple effect falling film evaporators operating on backward feed

flow scheme. 30% caustic solution at 80°C is fed to third effect evaporator. Vapours are separated from solution

and concentrated solution of third effect evaporator is pumped to second effect evaporator after passing through

two heat exchangers in series. In the second effect evaporator, flash evaporation of liquor takes place and liquor is

further heated by steam and vapours are separated in second effect evaporator to concentrate liquor.

PACL





The concentrate from the second effect evaporator is pumped through first effect evaporator after passing through

two heat exchangers in series. Steam at 11 kg/cm2(a) pressure is used to attain required concentration of caustic.

Chlorine Liquefaction & Bottling

Chlorine Gas Cooling

Chlorine Gas coming out of Electrolysers contains water vapours saturated at about 90°C and has little amount of

Sodium Chloride as entrainment. Gas is first passed through Chlorine Recuperator to recover heat in order to pre

heat brine being sent to Ion Exchange Columns for feeding the Electrolysers.

It is then cooled in two stages to reduce water vapours load , first by cooling water at about 30°C and then by

chilled water at approx. 10°C.

Chlorine gas temperature is generally around 15-20°C as cooling below 9-10°C will result into formation of chlorine

hydrate.

Sodium Chloride entrainment is removed by passing the gas through Wet Chlorine Filter Candles made of Glass

Wool.

Cooled gas is then dried with direct spray of sulphuric acid in packed towers.

Chlorine Gas Drying

The cooled chlorine gas is led to chlorine Gas Drying Tower. The moisture of chlorine gas is absorbed into

sulphuric Acid of 98% concentration fed into the two stage chlorine gas drying tower, and gets diluted to 78%

by absorption of moisture from chlorine gas. Chlorine Gas Drying Tower has a cooler to cool circulating sulphuric

Acid. The Dry Chlorine gas is sent for compression.

Chlorine Gas Compression

Dry chlorine gas from chlorine Gas Drying Section is compressed to 4 kg/cm2 (a) by using Acid Ring type

Compressor.

Chlorine Gas Liquefaction and Filling

Chlorine gas from compressor is sent to chlorine Gas Liquefaction Unit to be condensed by the Freon 22 refrigerant.

The unliquefied gases along with inert gas from Liquefier are sent to HCI Synthesis unit for burning with Hydrogen

to produce HCl.

Liquefied chlorine enters Chlorine Storage Tank from where it is transferred by means of compressed dry air to

chlorine bottling section. Part of liquid Chlorine is vaporised and sent to nearby customers through pipeline.

Waste Chlorine Neutralization / Sodium Hypochlorite Section

Waste chlorine gas, only in case of plant emergency, is led to the Sodium Hypochlorite Unit. Chlorine Gas during

start up and plant tripping is fed to the absorption tower. This unit consists of packed tower in which caustic

solution is circulated to absorb waste chlorine. Temperature of the liquid is controlled by heat transfer through plate

type heat exchanger with chilled water.

After a desired strength of sodium hypochlorite is reached, the solution is sent to a Hypo Reactor. Here it is reacted

with fresh chlorine to produce marketable quality Sodium Hypochlorite.

HCL Synthesis

The HCl Synthesis unit consists of combustion furnace fitted with absorbers. The chlorine gas reacts with Hydrogen

to form HCl gas which is cooled and absorbed in DM water. The flow rate of DM water is adjusted to obtain 30-33%

HCl Solution. The flow rates of Chlorine and Hydrogen are controlled by flow controllers. Safety Interlocking

PACL





provisions are made which get actuated by flame protection device. The Hydrochloric Acid Solution is collected in a

product tank from where is pumped to HCl Storage Tanks.

Hydrogen Bottling and Storage

Hydrogen gas is compressed and filled in hydrogen cylinder banks of the customers and also stored in cylinder

banks.

Caustic Soda and Flaking Plant

Flaker plant is a double effect evaporator. 48% Caustic is fed to produce 98% Caustic Flakes. Salt mixture (KNO3,

NaNO2 & NaNO3) which is heated by burning Hydrogen in a heating media to increase Caustic lye temperature in

final concentrator. 98 % Caustic flakes is then cooled and packed using a polythene liner to avoid moisture pick-up

as it is a hygroscopic product.

The process flow diagram is given in Figure 3-4.

3.5.2 Stable Bleaching Powder (New Plant) – 100 TPD

Stable bleaching powder (SBP) is manufactured as a consequence of composite chemical reaction between

hydrated lime and liquid chlorine.

The chlorination drum where the chemical reaction occurs, temperature is controlled by circulating water in jacket.

After complete chlorination, the product is dried under vacuum, cooled and discharged to packing hopper via

vibrating screen, which separates oversized material. The oversized material is further pulverized and mixed with

product. The reaction in the drum is as follows:

Ca (OH) 2 + Cl2 CaOCl2 + H2O

Stable Bleaching Powder contains 34% chlorine and is a powerful oxidizing agent. It is stable for a longer period of

time i.e. very low losses of available Chlorine over extended period of time, when properly stored even under

changing climatic conditions. This is because of low moisture content in the product and absence of heavy metal

impurities in the raw material. Above all the best quality Hydrated Lime and the Chlorine generated from its own

plant are used in the manufacture of SBP.

Process flow diagram of SBP plant is shown in Figure 3-5.

3.5.3 Hydrogen Peroxide (New Plant) – 50 TPD

Process Description

This process is based on circulating working solution, known as the auto oxidation process for Hydrogen Peroxide

production. The steps for the Hydrogen Peroxide manufacturing are Hydrogenation, Oxidation, Extraction and

Distillation. The working solution consists of two organic solvents AB and tributylurea and 2 EAQ (Ethyl Anthra

Quinone).

Hydrogenation

Working solution and Hydrogen are fed to hydrogenator and in the presence of palladium catalyst, 2 EAQ will be

converted to 2 Ethyl hydro anthrax quinine. The working solution, excess hydrogen and catalyst discharge from the

top of the hydrogenator. Gas and liquid streams are separated with the Hydrogen being returned to hydrogenator

via a recycle compressor. The working solution and catalyst flow to primary filters. Here a forward flow of liquid is

separated from catalyst and passes to an oxidizer feed tank while the reaming working solution and catalyst are

returned to hydrogenator.

Oxidation

The hydrogenated working solution is oxidized with air (oxygen) in an oxidizer. In this step of process Hydrogen

Peroxide is produced which is dissolved in working solution. The depleted air from the oxidizer will pass through the

solvent recovery system before discharge to the atmosphere.

Extraction

Working solution from the oxidizer degases into the bottom and demineralized water into the top of an extractor.

Due to different densities of the two phases, this working solution flows upwards and discharges from the top of

the extractors after being tripped of it hydrogen peroxide. The aqueous phase discharging from the bottom of the

extractor contains up to 35% Hydrogen Peroxide.

PACL





Product treatment

Hydrogen peroxide passes through coalesces, where traces of solvents are separated from Hydrogen Peroxide.

Purified Hydrogen Peroxide is pumped to the product day tank to the distillation.

Distillation

Crude Hydrogen Peroxide with a concentration of 35% is pumped to vaporizer system. The steam is supplied to

vaporizer for boil up to Hydrogen peroxide. The vapour from the vaporiser passes through the mist separator prior

to entering the bottom of an absorption columns. Hydrogen Peroxide, having a high boiling temperature than after

is the “Heavy” key component in the still, so it concentrate in the bottom at strength from 50% to 70%.

Demineralized water is use for the reflux in the column. The product is drawn from the bottom of the column and

pumped to the storage tanks.

3.5.4 Coal & Biomass based Captive Power Plant (New Plant) – 75 MW

Coal based Captive Power Plant (CPP) consists of 3 Units of 21 MW each and 1 Unit of 12 MW comprising

Condensing type steam turbine.

Punjab is predominantly rich in agriculture and contributes the major share to the grain basket of India. It has

surplus production of major crops. It produces 25% of country's cotton, 22% of wheat and 55% of rice, even

though it has only 1.5% of total country cultivable area. Punjab has been meeting its electrical power requirements

primarily through conventional thermal and hydro power generation. Hydro power generation has a tendency to

fluctuate depending on the availability of water. Thermal power generation has to depend on coal which has to be

transported from eastern part of India involving large distances. Cost of generation from coal continuous to

escalate and moreover it is polluting.

Punjab has the potential to generate about 2,000 MW of power using biomass alone. Considering this fact in view,

PACL has decided to use Bio-mass (initially) and coal in its proposed Captive power plants.

PACL





Basic process involves steam generation by combustion of coal & biomass in boilers. Steam will be used to run

turbine for power generation. Electricity will be generated at 11 KV and distributed to process plant.

Power plant will be mainly divided in following sections:

Biomass handling, Coal yard and Coal handling plant

Initially the Bio-mass fuel will be used to generate the Power. It will be procured during the season and will be

stored in the near vicinity of PACL premises, which will be hired on lease basis. Biomass will be stored in limited

quantity at site.

PACL shall also have facility to use Coal. Imported coal will be procured from local market. The coal will be

transported by road through dumpers / trucks / rail. Coal unloading activity involves unloading of coal from

dumpers and truck by JCBs in coal yard. Coal will be fed to coal bunker with the help of conveyor belt, screen and

crusher.

Boiler and auxiliaries

Four (4) Nos of CFBC boilers of 80 TPH capacities are proposed for generation of steam. To control air emissions

within the stipulated norms, ESP will be provided to reduce PM emissions, limestone will be dosed along with coal

to reduce SO2 emissions. And since, CFBC boilers are proposed, NOx generation will be limited due to lower

temperature operations. These consists of steam drum, water wall & economizer. Heat generated due to coal &

biomass combustion in the form of flue gas will be used at various levels in boiler to maximize thermal efficiency.

Steam will be passed through super heaters to achieve final temperature.

Steam turbine and alternator

High temperature, high pressure steam will enter in turbine where heat energy will be converted into kinetic

energy. Turbine is directly coupled to alternator where electricity is generated by electro motive force produced.

Three (3) Nos of Turbines of 21 MW capacities & One (1) turbine of 12 MW capacity will be provided.

Steam will be extracted for process and for heating water before feeding in boiler from various extraction points in

turbine. Power will be generated at 11 KV through and fed to different areas of chlor alkali plant through double

bus bar system to cater high reliability of electrical system.

Condenser system

Exhaust steam will be condensed and recycled in boiler with pumping devices at various stages with minimum

make up of D.M. water.

Utility

Instrument air compressors will be installed for requirement of air at various control valves.

Cooling tower with well-designed water distribution system for removing heat from condenser, alternator, oil

coolers and at various fan bearing locations will be provided. Existing raw water reservoirs will be used for catering

raw water requirement.

Ash disposal system

The ash from bottom will be trapped in ESP & will be stored in an ash silo. The ash shall be given for cement and

brick manufacturing, road construction and road backfilling inside and outside the factory premises, wherever

required.

3.8 Pollution Load on Environment due to project

Environmental issues include:

Air emissions;

Wastewater generation;

Noise generation;

Hazardous waste & Solid waste generation.

3.8.1 Air Emissions & Control

Volume Source

Particulate Matter (PM) emission from coal storage yard for proposed Coal based captive power plant is envisaged

as volume source emission as the same would be established within the existing premises.

Fugitive Emissions

Fugitive emissions of chlorine due to storage & handling of chlorine as well as that of PM due to storage of coal are

envisaged in the project.

Line Source Emissions

Approximately additional vehicular movement - 250 vehicles per day (200 trucks/tankers/tractor, 25 cars & 25 two

wheeler) is envisaged on SH-25 (Una-Naya Nangal to Chandigarh via Anandpur Sahib) which involves vehicular

emissions, majorly PM, CO & HC’s.

Point Source

Likely air pollutants from proposed project shall be HCl, Acid mist and Cl2 from process vents and PM, SO2, NOx

from proposed flue gas stacks, as point sources. These are in addition to the existing Flue Gas stacks & Process

Vents.

The ambient air quality & stack emissions will be maintained as per PPCB / CPCB norms.

Details of existing & proposed stacks with attached Air Pollution Control Equipment details are tabulated in Table

3.8.2 Noise Generation

From the proposed project, noise will be generated from the various activities. Source of noise generation are:

The heavy machinery like crane, dumper, roller, bulldozers etc. will be used during daytime during construction

phase;

Operation of Boilers, Turbine, DG sets, Cooling Towers, Pumps, FD-ID Fans & Compressors;

Vehicle movement for transportation of raw material & finished goods.

3.8.3 Waste Water Generation

The main source of the industrial wastewater generation will be from process, plant washings, cooling tower &

boiler blow down. The total quantity of effluent generation will be increased from ~380 KLD to ~1,745 KLD.

The untreated effluent, is sent to existing Zero Liquid Discharge (ZLD) facility which is a Zero Discharge plant based

on Reverse Osmosis (RO) followed by Multiple Effect Evaporator (MEE) processes. The RO permeate is sent back as

raw water make up.

The capacity of this plant will be increased to meet the additional effluent load.

Due to expansion activities, total effluent will be treated in the above facility and the RO permeate will be recycled

back as raw water makeup.

sanctuary from PACL is ~2.5 Km. Distance certificate shall be procured from the forest department. Map of eco-

sensitive zone of Nangal Wildlife Santuary with latitude and longitude is published vide Annuxure I of MoEF&CC

Notification S.O. 840(E) vide 16th March, 2017. The notification states “The Eco-Sensitive Zone is spread over an

area of 1.26 Sq. Kms with an extent upto 100 meters around the boundary of Nangal Wildlife Sanctuary”. Thus, the

proposed project does not require Wild Life Clearance.

4.3 Topography

The Project site is shown on OSM sheet in Figure 3-2.

4.4 Existing Infrastructure

Existing infrastructure like roads, power supply, water supply line, etc. are readily available at the site.

4.5 Soil Classification, Geology & Drainage

4.5.1 Soil Classification6

There are two types of soils are found in the district- (1) Reddish chestnut soils which is seen in the northeastern

part of the district, particularly in the Rupnagar and Anandpur Sahib blocks. These soils are loam to clay-loam in

nature and de-calcified. (2) Tropical arid brown soils (weakly solonized) are mainly found in rest of the area which

are mainly calcareous sandy loam. The soils of the District vary in texture generally from loam to silty clay loam

except along the Sutlej River and chos (seasonal canals) where some sandy patches may be found. Chamkaur

Sahib and Morinda blocks have sodic soils. The soils of Anandpur Sahib and Rupnagar blocks are undulating.

4.5.2 Geology

Geology of the District7

Geologically, the rocks are disposed into two broad belts; outer and inner, formed of the upper and lower Tertiary

period respectively. The rock formation met with in the upper Shiwaliks consist of soft earth clay and bouldary

-------------------------------------------------------------------

PACL





conglomerates. The middle shiwaliks are composed of massive sand rock and clay beds. The lower Shiwaliks have

grey micaceous sand stones and slabs and are unfossiliferous. The piedmont plain area is composed of the alluvium

derived from these shiwaliks intercepted by seasonal rivulets or ' choes'. The soils derived from these formations

are unstable and prone to erosion, indicating the desirability of permanent vegetation especially on the hill slopes.

Geology of the project site

This will be detailed in the EIA report.

Geomorphology8

The entire district can be grouped into 4 units such as Siwalik Hills, Intermontane valley, alluvial fan and alluvial

plain. The Siwalik Hills separates the main Himalayan ranges from the Indo-Gangetic alluvial plain. The area is

highly dissected and has an uneven topography. Adjacent to the hills is a long narrow intermontane valley, which

extends from Nangal to Rupnagar trending northwest to southeast. Anandpur Sahib tehsil of the district lies in the

intermontane valley and occupies a length of 40 km. The average width of the valley in the district is 5 km. Sutlej

River and its tributaries drain in this valley. Adjacent to this is the alluvial fan which forms the transitional area

between the alluvial plains and hilly area of Himalayan foot hills. The coarse sediments brought down by hill

torrents forms the alluvial fan deposits. These alluvial fans coalesced to form Kandi and Sirowal formation. The

southern part of the district is mainly alluvial plain, which forms a part of vast Indo-Gangetic alluvial plain.

Seismicity of the study area

The area comes under the high damage risk zone (Zone-IV) of the Seismic Zonation of Punjab State9.

4.6 Climatic data from secondary sources

Based on the long-term climatological tables (1996 – 2009) published by Indian Meteorological Department (IMD)

of Bhiwani (Chandigarh) for October-December, the mean daily maximum temperature was recorded as 33.2°C.

The maximum and minimum mean hourly relative humidity recorded are 81% and 49% respectively. Average wind

speed for post monsoon season is 1.56 km/hr (0.43 m/sec). Pre-dominant wind direction in post monsoon season is

from NW (20.3%) followed by SW (8.7%) & NE (7.5%).

Site specific meteorological data will be collected during the Baseline Environmental Monitoring for post monsoon

season for the year 2018.

4.7 Social Infrastructure Available

Key infrastructure such as schools, colleges, hospitals, schools, bank, places of worship and social / community

facilities such as park, market, playground etc. education, health care, community development, income

distribution, employment and social welfare are available in Naya Nangal as well as Nangal towns.
