b. Air Inventory of Air emissions from the EMC and mitigation measures proposed to be taken are covered in Section 4.5.2 in Chapter 4 of the EIA Report

c. Liquid wastes Total wastewater generation in the EMC will be around 1.96 MLD (0.18 MLD from cooling tower blow down, 0.36 MLD from process, 1.416 MLD from sewage and 0.06 MLD from miscellaneous activities). For the wastewater treatment Common Effluent


Page 8

Treatment Plant (CETP) of 2 MLD is proposed which comprised of a STP and two ETPs.

4. Habitat/wildlife Issues of concern Actions proposed to be taken

a. Impact on Flora Ecologically sensitive areas

like Biosphere Reserves, National Parks, Wildlife Sanctuaries protected sites as per Ramsar convention and other protected areas (PA) are not found within 10 km radius of the project site.

Patches of Reserved Forests and Protected Forests are located in General study area

The land is uninhabited and major part of the project area is devoid of large trees. Baseline status of vegetation clearly suggests that project area is mainly barren land devoid of large trees and mainly consists of scattered and sparse vegetation i.e. Prosopis juliflora, a few scattered individuals of Casuarina equisifoliata, Mangifera indica Phoenix sp., Cocos nucifera & Borassus flabellifer. However, their population is quite small and isolated in the buffer area. In addition few minor plantations by villagers such as neem, mangos are also observed which will be cleared.

Since patches of forest plantation are located in buffer area, it will be taken utmost precautions not to further degrade these areas by constructing temporary roads, dumping materials, solid wastes, garbage or any other form of material in to the surrounding grasslands. Rest of the project activities may not have any significant impacts on the vegetation of project area and surrounding area, in general, and on the plant species of higher conservation significance, in particular.

b. Impact on Fauna It is observed that there are

number of small to medium seasonal water bodies and forest plantation patches present in 10.0 km periphery of the proposed project and therefore envisaged that during winter season flocks of migratory birds may move between these water bodies.

In the project area only domestic and feral animals such as cattle, goats, crows, dogs and cats were observed.

It is suggested that maximum precautions shall be taken during construction phase and as well as during operational phases so that the nearby water bodies will not be disturbed.

c. Migratory Paths for Wildlife and Forest Blocks There are no identified

migratory paths for major and minor wildlife in the project site and the study area. The identified fauna which are observed at the project site and in the study area are local migrants only. Therefore the proposed EMC operations are not likely to have any adverse impact on the paths for avi-

Discharge of wastes/wastewater without treatment into the water bodies during the construction and operation will not be allowed

Awareness will be given to workers about the importance and conservation of terrestrial ecology and biodiversity

fauna. 5. Potential sources of industrial accidents, explosions and fires, health and safety issues

Potential sources Actions proposed to be taken a. Accidents during Construction

Phase o Mechanical Hazards o Transportation Hazards o Physical Hazards o Storage and Handling of

Hazardous Materials Accidents during Operation

Phase o Material Hazards o Mechanical Hazards o Handling, Storage and

Transportation Hazards o Plant/Industry Hazards

Accidents due to Natural Calamities o Earthquake o Cyclone/Flood

Risk Assessment studies were carried out for the potential industries causing accidents, explosions and fires, health and safety issues and present in the EIA report.

Proper wiring of the electrical appliances like lights, exhausts, etc., would be made to ensure that there are no live wires causing short circuits to ignite materials.

All electrical fittings and cables are to be provided as per the specified standards.

Spillages are to be collected and neutralized for toxic contents before disposal.

Extra care shall be taken by providing rupture disc, pressure release valve and temperature controller

Eye wash/Drench shower is to be provided at a strategic location for emergency purpose

Chemical Safety Data Sheets and handling procedure, First Aid measures are to be prepared and displayed for information and safety of the working personnel.

Other Risk mitigation measures are covered in Section 7.2.5 in Chapter 7 of the EIA Report

Annexure-D

Landscape plans with

proposed tree plantation


Page D-1

Annexure D Landscape plans with proposed tree plantation D.1 Greenbelt Development Plan Trees play a vital role in the environment in preventing the horizontal dispersion of the pollutants to the surrounding areas. Trees are very suitable and effective for detecting, recognizing, reducing and controlling air pollution, minimising noise pollution and will also check soil erosion, make the ecosystem more complete and functionally more stable and conducive.

Owing to their large surface area besides their bio-aesthetical values trees are to be used as indicators of biological effects of pollutant.

D.1.1 Objectives of Greenbelt Development Plan

The objectives of greenbelt development plan are as follows:

Mitigation of Fugitive Emissions and improve ambient air quality Provide a shelter belt around the project area for dust absorption and noise reduction Prevention of land degradation due to activities during construction phase Balancing Eco Environment Enhancement of the overall environmental quality Provide adequate shelter and habitat to the local fauna Enhancing the ecological equilibrium of the area Providing aesthetic value to the project area Conserve soil quality and improve moisture level in ambient atmosphere Compliance of the conditions stipulated in the environment clearance Improving the forest cover and maintaining the biodiversity of the region Create awareness for environmental conservation and tree planting Generate employment for the local people

D.1.2 Greenbelt Areas

Greenbelt/green area development will be carried out in and around the EMC, along the boundary, roadside and on the vacant areas with above objectives. A total area of 61.25 Acres was earmarked for greenbelt/green areas development which is about ~12.2% of total EMC area and provisions shall be made for green area development of additional ~33% of total area in upcoming industrial units. Width of the green belt is varying from 10-20m (more width near the habitation).

D.1.3 Plant Species for Greenbelt Development

Emphasis shall be on native plant species on the basis of air pollution tolerance index of tree. The selection of plant species for the development depends on various factors such as climate, elevation and soil.

While selecting the plant species for the proposed greenbelt, they should exhibit the following desirable characteristics in order to be considered:

Tolerance to specific conditions or alternatively wide adaptability to eco-physiological conditions

Fast growing type and providing optimum penetrability Capacity to endure water stress and climate extremes after initial establishment Should be wind-firm and deep-rooted Should form a dense canopy and perennial green Species tolerant to air pollutants like PM, SO2and NOX should be preferred


Page D-2

Be able to attenuate noise generated within the area Native origin and locally available Be well adapted to the existing soil conditions Should have a large leaf area index. Should be permeable to help create air turbulence and mixing within the belt Introduction of monocultures and alien plant species would be avoided to the maximum

possible extent Should be able to thrive along with diverse species

D.1.4 Greenbelt Development Plan

The greenbelt development plan for the proposed EMC is based on “Guidelines for Developing Greenbelt” published by Central Pollution Control Board (CPCB). Greenbelt is proposed along the EMC boundary. Green areas are also proposed near the common utilities to serve as recreational facilities and breathing spaces and also to create buffer zones. The three tier tree plantation shall be ideal recommendation for greenbelt around the boundary of the proposed EMC.

D.1.4.1 Design of Greenbelt

While the greenbelt will be developed as per CPCB guidelines with concept of three tiers greenbelt development with tall, medium and short height permanent trees in general. A survey was conducted with respect to existing forest types and vegetation diversity in the project area for development of greenbelt around project components.

The following guidelines will be considered in greenbelt development.

The spacing between the trees will be maintained slightly less than one meter to increase the density

Planting of trees in each row will be in staggered orientation In the front row shrubs will be grown. The short trees (<10 m height) will be planted in the first two rows (towards plant side) of

the green belt. The tall trees (>10 m height) will be planted in the outer three rows (away from plant side)

Tall trees one line and short trees one line will be planted around the industries blocks to control the fugitive emissions and to reduce the noise.

Pits measuring approximately 2’x2’x2’ may be dug where the soil is reasonably deep, and, pits measuring approximately 3’x3’x3’ where the soil is shallow or gravelly.

Expose the pits to direct sunlight for about 15 days and

o If the soil at the site is reasonably good, pits may be filled with 80% site-soil +20% composted cow-dung. About 200 gm Neem-cake and leaf-litter, grass or agricultural residue may be added

o If the soil at the site is poor, pits may be filled with 35% site-soil + 35% fertile soil (from an external source) +30% composted cow-dung. Neem-cake and other organic matter may be added as in the previous instance

Saplings should ideally be planted after the annual rains begin. The saplings would need to be watered once the rains cease.

Saplings shall be suitably nurtured and maintained. Soil conditioning and fertiliser application shall be undertaken. If required, suitable soil treatment shall be provided to ensure good growth of tree cover.


Page D-3

Construction of temporary shelters of locally available materials such as bamboo and grass around the growing saplings is recommended in the summer, to help the plants withstand the hot sun.

During construction period

o Ground-vegetation should be allowed to shed seeds before cutting or moving it for mulch. This would leave behind a seed-bank to flourish in the next growing-season, providing a natural source of mulch for the following year.

o Open Burning of bushes and other waste on land must be avoided, as it reduces soil-quality, and harms the ground-vegetation, amphibians, reptiles and ground-nesting birds.

Development of greenbelt shall start with construction phase and shall be continued full fledge with operation phase of the proposed EMC.

As a part of improving biodiversity areas need to be ear marked for the growth of creepers that are always neglected in greenbelt development category. Creepers are becoming increasingly threatened due to lack of concerns and selective dereliction of this species.

The indicative sketch of three tier greenbelt development is given in Figure D-1.

Figure D-1: Hypothetical Representation of Three Tier Greenbelt Development

D.1.4.2 Cost estimations for Greenbelt Development

Approximately 61,968 trees are proposed to be planted in entire EMC to follow the concept of 2500 trees/Ha. The survival of the plantation shall be monitored frequently and survival rate of the plantation during operational phase shall not be less than 80%.

A capital cost of INR 15.49 million (Rupees 1.55Crores) shall be earmarked for this purpose and INR of 2.60 million (Rupees 0.26 Crores) shall be allocated for recurring expenses towards greenbelt development and maintenance. In addition to this, all other industrial units shall develop green areas within their premises as per the prevailing Andhra Pradesh Pollution Control Board (APPCB) provisions.

D.1.4.3 Recommended Species for Plantation

Based on climate and soil characteristics of the study area, some species are recommended for plantation. The climate of the region is extreme where there is heavy rainfall as well as

Annexure-F

Rainwater harvesting plan


Page F-1

Annexure F Rainwater Harvesting Plan Rainwater Harvesting (RWH) refers to collection of rain falling on earth surface for beneficial uses before it drains away as run-off. However as a developmental activity to improve groundwater in the region rainwater harvesting is proposed within the EMC. Rainwater harvesting and conservation practices reduce the soil erosion, increases soil moisture and enhance recharge to groundwater body.

The objectives of rainwater harvesting proposed for the EMC are as follows:

Rainfall – runoff management Control soil erosion Increase the soil moisture Prevent rush of surface flow of water Recharge to groundwater in favourable areas Direct use of harvested rainwater Saving in pumping cost

F.1 Estimation of Rainwater Harvesting Potential

Rainwater Harvesting shall be implemented at EMC to conserve rainwater. Rooftop area, greenbelt/green area, road/paved area and open areas proposed in the EMC are considered for calculating the amount of rainwater that can be harvested.

The approximate quantities of rainwater that can be harvested at EMC are given in Table F-1. The equation used for run off estimation is based on CPCB guidelines on ‘Concepts and Practices for Rain water Harvesting’ - Oct 2001. The calculations are based on the following:

Average annual rainfall is 1133.9 mm based on 1980-2000 IMD data Average No of rainy days are 56.6 Run of co-efficient are considered as given by CPCB guidelines

F.2 Harvesting Plan and Recharge Structures

F.2.1 Rooftop Rainwater Harvesting

Rooftop rainwater harvesting is one of the appropriate options for augmenting groundwater recharge/storage where natural recharge is considerably reduced and not much land is available for implementing any other artificial recharge measure.

In a typical roof top rainwater harvesting system, rainwater from the roof is collected in a storage vessel or tank for use during periods of scarcity. Such systems are usually designed to support the drinking and cooking needs of the family and comprise a roof, a storage tank


Page F-2

and guttering to transport the water from the roof to the storage tank. In addition, a first flush system to divert the dirty water, which contains debris, collected on the roof during non-rainy periods and a filter unit to remove debris and contaminants before water enters the storage tank are also provided. Therefore, a typical Rooftop Rainwater Harvesting System comprises following components:

Roof catchment Filter unit Drain pipes Storage tank. Gutters

Collection sump. Down pipe Pump unit First flush pipe

A typical Rooftop rainwater harvesting system is given in Exhibit F-1. However, during detailed engineering of the industries suitable structure will be arrived for rainwater harvesting.

Exhibit F-1: A Typical Rainwater Harvesting System

Filtration forms the most important process in the purification of water. It usually involves allowing water to pass through a filter media e.g. sand. Filtration essentially involves removal of suspended and colloidal impurities present in water. Depending on the type of filtration, the chemical characteristics of water may be altered and the bacterial content may be considerably reduced. These effects take place due to various processes such as mechanical straining, sedimentation, biological metabolism and electrolytic changes.

The sand being used for filter in rooftop rainwater harvesting systems should be free from clay, loam, vegetable matter, organic impurities, etc. and should also be uniform in nature and grain size. There are three types of filters:

i) Slow Sand Filters ii) Rapid Sand Filters (gravity type) iii) Pressure Filters

F.2.2 Storage Ponds/Tanks/ use of Existing nearby Pond

In addition to roof top rainwater harvesting, industries in the EMC will also adopt storage tank /pond system for storm water storage. Storage ponds/tanks are civil structures to store


Page F-3

harvested rainwater. From these storage facilities, water can be pumped directly to points of demand or supplied through over-head tanks. Silt trap pits and filter beds have to be maintained before letting the water to the storage pond / tank. The storage tanks may be properly cemented to avoid leakage or seepage into ground. Dimensions of these structures may be maintained at 20 m x 10 m x 2 m. A model of the storage pond/tank is shown in Exhibit F-2 for storing harvested rainwater. Or the option of utilizing nearby existing pond/tank (Govindavaram) is also suggested.

Exhibit F-2: A Model Storage Pond/Tank

F.2.3 Recharge Pits-Typical Arrangements

In the project area, recharge pits are recommended to be constructed near the roof-top harvesting structures. Due to enhanced vertical hydraulic conductivity through the recharge pit structure, natural recharge process of aquifer system gets enhanced, especially when storms are of short duration and rainfall days are less as in case of project area, and sustainability of the aquifer is ensured for a long period. The benefit accrued during heavy rains in non- rainy (summer) season or during draught time will be worth mentioning. In such circumstances recharge will be at its peak stage. As a result all shallow open wells and ponds will get adequate quantity of water as huge relief for farmers and poor landless villagers.

In addition to rooftop rainwater harvesting, recharge pits will be planned by the industry and EMC authorities for rooftop harvesting. In the EMC area, recharge pits of 2.0 m diameter with a depth of 3.0 m will be constructed. The pit has to be back filled with a sequence of


Page F-4

boulders, gravel, pebbles and coarse sand from bottom to top. A constructed model recharge pit is shown in Exhibit F-3. A schematic diagram of the recharge pit is given in Exhibit F-4. It is recommended to dig a trial pit of 5.0 m before constructing the recharge pit. The site may be avoided if groundwater table is encountered within a depth range of 5 m.

Exhibit F-3: Model Recharge Pit (Source: Google)

Exhibit F-4: Schematic of Recharge Pit (Source: Google)

F.2.3.1 Recharge Wells-Typical Arrangements

Recharge wells are the structures to recharge water in the sub-surface levels directly to the aquifer. Gravity recharge wells in the vicinity of storage ponds are useful in recharging the deeper aquifer system.

A schematic design of the recharge well is presented in Exhibit F-5. The collected rain water in the pond may be diverted through well maintained channels, two desilting pits and two filter beds into each recharge well by gravity. From bottom of last filter bed, pipe carrying the recharge water may have to go down the recharge well up to piezometric surface.

F.2.4 Rainwater Harvesting and Utilisation Plan

Based upon hydrogeological conditions of the project area, harvesting and recharge structures are proposed for rainwater harvesting and groundwater recharging. The proposed harvesting and recharge structures in EMC are:

Roof-top rainwater harvesting Storage ponds/tanks

Recharge pits Recharge shafts/wells

The flash flood water can be recharged directly to the deeper aquifer through recharge wells for enhancing the depleting resource and make it sustainable.

Rainwater which will be harvested from building roof-tops can be stored at higher level storage tanks below the roof-top level and be directly supplied by gravity flow to the points of demand without the process of pumping. This water can also be used as grey water for domestic flushing purposes. The overall rainwater that could be harvested by implementing rooftop rainwater harvesting is estimated to be about 6,57,480m3 in a year.

Harvested water should be sent through desilting and filter bed pits to allow silt-free water into the storage facilities. Dimensions of these structures may be maintained at 20m x 10m x 2m and proposed conservation structures (i.e. about 15 nos. are suggested) are expected to harvest and store at least about 6000 m3The overflow water during heavy rains can be diverted to outfalls through proposed storm water drainage.

F.2.5 Monitoring Wells for Impact Assessment

The effectiveness of artificial recharge structures is known by closely monitoring the groundwater levels of the phreatic and confined aquifer systems. Monitoring of the groundwater regime is done by establishing a network of observation wells tapping the shallow and deeper aquifer systems separately.

The phreatic aquifer can be monitored by measuring groundwater levels in the open dug wells or dedicated shallow water table wells. The existing dug wells may also be selected for monitoring. Piezometric surface in the deeper aquifer may have to be monitored by installing dedicated piezometers. Piezometer is a small diameter (38 mm) tube with a 2 to 3 m perforated pipe at the bottom lowered in a borehole (100 to 150 mm) drilled down into the confined aquifer. The perforated portion of the tube has to be positioned against the bottom of the confined aquifer with clean sorted gravel shrouded between the tube and the borehole surface. Rest of the borehole may be filled with unsorted gravel or clay.

The observation wells/piezometers are to be monitored at least four times in a year, i.e. in the months of January, May, August and November. Data collected from these wells, provide more meaningful record / database and clarity in the changes in the ground water regime in the Project area.

Digital water level recorders, which collect water level information automatically ranging in time from 1 hour to 1 month, provide accurate and valuable data for groundwater management. The recorder is an electronic device which is installed within the water column of the observation well. The device collects the groundwater level data at the desired interval of time and stores the digital data on board which can be retrieved through data retrieval systems or hand held computers and can be downloaded directly into office computers for further analysis. Groundwater chemical quality monitoring also can be done through these devices with appropriate add-on probes.

Annexure-G

Storm water drainage


Page G-1

Annexure G Storm water drainage Storm water drainage arrangement is proposed along road side to cater water from the road surface and adjoining land area of project site. Accordingly each road side drain runoff is arrived and connected to road side drain on downstream side, forming as grid type arrangement based on the natural slope (gravity flow) which has finally to be discharged into natural stream located south-eastern side of the project site. The surface and sub-surface drainage system is designed as per IRC SP: 42 and 50. A minimum longitudinal gradient of 0.3% is maintained in such a way that it attains the minimum self-cleaning velocity of storm water drains. Closed box, Open box and trapezoidal type storm water drain are proposed along both side of the new construction road in project site. The factors considered for the design of storm water drainage is as follows.

Storm drains are designed to route peak runoff generated by rainfall of IRC specified duration and recurrence interval. As per Section 10.11 of IRC SP: 42, design storm shall be taken for 25 years return period for National Highway. One hour rainfall data for 25 years return period in the project area has been considered as 101 mm as given in Fig 6.(b) of IRC SP: 42

The peak runoff or the peak discharge for the given area is found out by using the formula Q= 0.028 PAIc as per Section 10.4 of IRC SP 42: Where Q = Peak runoff rate cum/sec; P = Coefficient of runoff for catchment characteristics; A = Catchment area in hectares; Ic = Average rainfall intensity in cm/hr from intensity-duration frequency relationship for a specific return period and duration t in minutes.

Coefficient of runoff (P) for the given catchment area is not constant and it depends on porosity of soil, type of ground cover, catchment area, slope and initial state of wetness and duration of storm. The suggested values of ‘P’ used in Rational Formula as given in Table 2 of IRC SP: 42. The values of Co-efficient of runoff (P) have been considered for the project stretch: (i) Main Carriageway, Service Road and Paved Shoulder -0.9 (ii) Earthen Shoulder, Embankment and Ground Surfaces -0.3

The area of runoff catchment for each link road is considered as half of road width (from centre to drain location) and adjoining land width. Adjoining land width towards the drain location is considered as per grading plan

Time of concentration for surface flow of water (As per Section 4.4 of IRC SP: 50)

As per Section 10.10 of IRC SP: 42, the rainfall intensity for shorter durations of small catchments is estimated

Hydralic design: Minimum width of line drain – 0.25 m (As per section 4.9.3.c of IRC SP: 50)

Minimum free board required as given in the Section 4.9.3 of IRC SP: 50 are (i) Drain width Less than 300 mm bed width - 10 cm as Min FB; (ii) Drain width Beyond 300 mm and up to 900 mm bed width - 15 cmas Min FB; (iii) Drain width Beyond 900 mm and up to 1500 mm bed width - 30 cm as Min FB; and (iv) Drain width For Larger Drains - Up to 90 cmas Min FB

Manning’s coefficient (n) is considered as per Table 6 of IRC SP: 42 and the ‘n’ value adopted are (i) Open Box drain- 0.014; (ii) Trapezoidal pcc lined drain -0.014 and (iii) Closed Box drain - 0.014

As per Section 4.9.1 of IRC SP: 50, the velocity of drain is calculated using Manning’s equation. Minimum self-cleaning velocity (0.75 m/s) and allowable velocity (6.0 m/s) for


Page G-2

different drains are considered as given in section 4.9.3 of IRC SP: 50 and Table 6 of IRC SP: 42.

Capacity of the longitudinal box and trapezoidal open drain is normally designed using Manning’s equation as given in Section 11.2 of IRC SP: 42

The cross sectional elements of the culvert structures shall be provided in accordance with the requirements of MoRTH specifications

So that sewerage system shall be adequately designed to carry the wastewater generated from the area and the industrial effluent collection system is proposed by tankers, primarily for the collection of industrial effluent from the cooling tower process units of the industries.

For the wastewater treatment Common Effluent Treatment Plant (CETP) of 2 MLD is proposed. Transport of process wastewater shall be by tankers only. The wastewater shall be received at the CETP and its pathway of treatment shall be arrived at based on the nature of the characteristics of the wastewater. Total length of the domestic wastewater collection network is 18.40 km of RCC NP2 and NP3 pipes. The diameter ranges from 200 mm to 300 mm. Details of the treatment plant is provided in the subsequent sections which comprises of an STP and two ETPs (ETP-I and EPT-II).

H.1.1.1 Wastewater Generation

Based on the demand, the following are the major consumers of water:

Since the units shall be electronic and related type, many places there shall be requirement of clean and air-conditioned facilities. It has been considered that for total air conditioning, the refrigeration requirement shall be 6600 TR.

With a ΔT 8°C, and initial raw water TDS of 300 mg/L the cooling water requirement has been worked out at 1,000 kl per day (for makeup) of which 180 kl per day shall be discharged as blowdown water. The balance shall be lost by way of evaporation and drift.

About 80% of the raw water supplied for the domestic use at industries and hostel shall be generated as wastewater. Entire water used in gardens shall be lost as seepage/ percolation water.

The units are expected to use about 400 kl per day of water in the process. The quality of water used at the process could be raw water as such or high purity water depending on the requirement. About 360 kl per day of wastewater is expected to be generated from process.

The wastewater is then taken to grit chamber for removal of grit. Here two grit chambers are provided which are to be used in cyclic manner and are to be manually cleaned. The wastewater is then led to a sump. From the sump, the wastewater is pumped to an equalization tank at an elevated level (as per requirement of APPCB) for attenuation of variation in waste flow rate and characteristics. For mixing to avoid solids from settling and development of anaerobic conditions, air shall be bubbled in the equalization tank through a grid placed at the base of the tank. The wastewater from the equalization tank is pumped at a uniform and constant rate for secondary treatment. UP TO THIS STAGE ALL UNITS ARE DESIGNED FOR THE ULTIMATE CAPACITY OF 1600 Kl/Day.

H.1.1.3.3 Secondary treatment

Wastewater from the primary treatment is subjected to bio-chemical oxidation in aeration tank. An attached growth Fluidized Aerobic Bed (FAB) system working as an extended aeration system is proposed. Air for aeration is supplemented by means of blowers connected to air diffusers. For immobilizing the microbes, high surface area to volume ratio synthetic media shall be provided in the aeration tank. This system has the following advantages:

Smaller foot print area Ease in operation and maintenance


Page H-4

Operator skills required are minimal System less susceptible to upset conditions (shock loading, power failure, etc.) Lower energy requirements No clogging or chocking of the media.

Following bio-chemical oxidation, the wastewater from the aeration tank is taken to a tube-deck (secondary settling tank) for solid-liquid separation. The sludge collected in the hopper bottom of the settling tank is periodically withdrawn and applied to the sludge drying beds for dewatering and drying. The underflow of the sludge drying beds is sent back to the equalization tank.

H.1.1.3.4 Tertiary treatment

Overflow from the settling tank is subjected to tertiary treatment. The first stage is chemical oxidation tank for chemically oxidizing the residual contaminants. Chlorine as sodium hypo chlorite shall be added for chemical oxidation. For adequate contact time a chlorine contact chamber with 30 minutes detention time and mixing arrangement (baffle walls) is proposed. The wastewater from chlorine contact chamber is then collected in an intermediate sump and pumped to a pressure sand filter for removal of particulate matter. The wastewater is then taken through an activated carbon column for removal of trace organics and pollutants (chlorine, colour, trace organics, etc.). The backwash of the pressure sand filters and activated carbon column are taken to sludge drying beds.

The overflow of the carbon filter is taken to the UF sump at the main ETP for further treatment and recovery of water for reuse.

The above 2 stages are designed in 2 modules. One module will be established now

and the other module in due course of time as and when the occupancy of the park

reaches beyond 50%.

H.1.1.3.5 Salient features of the proposed system

The following are the salient features of the system being proposed:

The entire plant is virtually maintenance free No special operational skills (sludge recycles, etc.) are required Total area required is minimum The system is rugged and is easy to operate and maintain System has been optimally designed At all critical points stand-by provision has been made

H.1.1.4 ETP-I

ETP-I is designed for:

a) Exhausted process bath solutions b) Wastewater from Electro-plating (reuse water and exhausted process bath solutions)

To cater for most needs, a 2 stage reaction followed by settling is provided. This plant can cater to fluoride bearing wastewater, chromium bearing wastewater, cyanide bearing wastewater and other wastewater streams.

H.1.1.4.1 Proposed Scheme of Treatment of ETP-I

Proposed scheme of treatment is shown in Figure H-2.


Page H-5

Figure H-2: Proposed Scheme for High strength batch discharge, CN- & Cr Streams

Depending on the quality of the wastewater to be treated, the chemical to be used for treatment will have to be changed. For e.g.:

- Fluoride: Ca(OH)2 + MgO

- Cyanide: Na(OH) + NaOCl

- Chromium: Sulphuric Acid, FeSO4, Lime

The treated wastewater from this section shall be taken to ETP-I for further polishing treatment before being fed to the membrane and evaporation system.

For those streams having TDIS > 20,000 mg/L, it is proposed to add the pre treated effluent directly at the feed to MVR.

All sludge /solid wastes shall be dewatered and sent through authorized waste handler for ultimate disposal.

Fire protection measures


Page J-1

Annexure J Fire protection measures & approvals obtained J.1 Fire Protection Facilities Proposed EMC product verticals and focused horizontal Industries are prone to hazards including fire, In order to provide the best facilities to fight the hazards related to fire, the following fire protection services with automated response system are conceived:

Dedicated firefighting water network

Fire stations strategically located within the cluster

In addition to this, the statutory requirements (as per Development Control Rules) for firefighting provisions within individual industrial plots to be enforced as a part of the development guidelines. As per this, each industrial unit should have storage tank + fire pumps + hydrants.

Fire mitigation system consists of Fire station (1,000 sft), fire fighting facilities, fire water storage and Distribution system is proposed as part of essential services in EMC. A total of 114 numbers of fire hydrants are proposed at 45 m distance on water lines along major roads only (45m & 30m).

J.1.1.1 Fire Detection and Alarm System

Fire detection and alarm system can be provided for the entire area which will be microprocessor based Intelligent Analog Addressable type. The system will consist of central monitoring station located in unit control room. A comprehensive fire detection and protection system will be envisaged for the complete power station. This system will generally conform to the recommendations of TAC and NFPA (latest edition).

J.1.1.2 Automated Response System

An automated firefighting system for the cluster is conceived to respond to fire outbreak without any delay in response time. The automated system mainly includes means of detection, actuation and delivery. The fire detectors could be operated mechanical or electrical means as explained below:

Mechanical detection uses fusible-link or thermo bulb detectors that are designed to separate at specific temperatures and thus actuate alarm system

Electrical detection uses heat detectors equipped with self-restoring, normally open contacts which close when a predetermined temperature is reached. These detectors are connected to alarm systems which activate the delivery system.

The fire detectors along with an alarming system shall continuously monitor facilities throughout the project site in case of a fire outbreak. The fire detection devices (smoke detector, thermal detector, infrared flame detector, manual alarm, limit switch, flow switch, etc.) to be placed at identified locations. Signals are then transferred by local fire control panels to the main fire control. The main control room/ fire stations are alerted of the need for fire-fighting or evacuation efforts once the signal has been processed by software in the main fire control panel.

The delivery system is accomplished by means of piping and nozzles or sprinkler system. Though commonly water is used as the exclusive fire suppression agent, it still has its limitations. Different extinguisher types along with water and firefighting media are given in the Table J-1.

Annexure P Vehicle Parking and Management P.1 Internal Roads

Following are considered during the planning stage of Internal Roads:

The design philosophy for road pavement and bridges / structures is based on IRC prescribed for design, execution, maintenance and safety during construction and service with latest additions and amendments

The project site is located in plain terrain (cross slope of ground – 0 to 5%). The design speed of the proposed internal road & external road is considered as 40 km

per hour & 50 km per hour respectively for the aspect of safety consideration. The proposed internal road network plan is designed as per IRC 86-1983: Geometric

design standards for urban roads in plain. Since IRC standards do not specify standards for median widths, raised or sunk median, shyness strips etc., these aspects are proposed as per 6/4 lane manual and MoRTH circulars.

The intersections are designed in accordance with IRC: SP: 41-1994, ‘Guidelines for the Design of At-grade Intersections in Rural and Urban Areas’. The minimum turning radius of 20m is considered at each intersection for more usage of long vehicle type in the site.

Essential Road Furniture’s (Traffic Control Devices, Road Delineators, Road Studs, Roadside Safety Barriers, Pedestrian Guardrails and Facilities, Access Control)

IRC: 37 – 2012, “Tentative Guidelines for the Design of Flexible Pavements”

Based on the master plan, total length of internal roads is estimated as 10.233 km, length of external road is estimated as 2.8 km. The road cross-sections are developed based on the RoW provided for various categories of roads as per master plan. The cross sections also include foot path cum utility corridor such as storm water, drinking water, sewage water, recycled water and power and telecom network. The following shows the cross sectional elements for each RoW considered in the master plan.

P.1.1.1.2 Passenger Traffic

Basic Assumptions in Processing Area and Non-processing Area

The direct employment in processing area was provided as 28,500. The sector wise employment considered for the passenger trip generation is as presented in Table P-6.

Table P-6: Sector-wise Direct Employment in Processing Area S. No. Sectors Total Direct Employment

1 Electronic Product Manufacturing 12306

2 Semi-Conductor Designing and R&D centre 2694

3 Electronic Component Manufacturing 8200

4 Manufacturing and Other Support Services 2800

5 Essential Services 1250

6 Welfare Services Facilities 1250

Total number of direct employment 28500

The total number of trips made by the employees of various sector includes to and fro movement which leads to twice the total number of employees (i.e. 57000 trips).

In the total direct employment, 30% of people are assumed to stay in Non-Processing area and the remaining 70% will stay outside EMC.

Also a trip rate of 0.5 trips per day is assumed for the trips made by the family members of the employees living inside EMC who are assumed to contribute 30% of the total direct employees.

For passenger vehicles, considering the total working hours on a three shift basis, the general shift was assumed with peak hour traffic of 40%. Also 50% of the family members are assumed to travel during the peak hour.

Assessment of the passenger trips involves the following steps. PCU factor and occupancy ratio considered for each passenger vehicle is as presented in Table P-7.

With the assumed modal spilt, the number of employees arriving in each sector of processing area and non-processing area is estimated mode-wise and the number of passenger vehicles generated is also arrived.

The modal split assumed for the people who carries out internal work trip within EMC i.e., from non-processing area to processing area as well as trips made by family members plying out of EMC is also presented in Table P-7.

Special chartered buses can be proposed for employees inside the non-processing area as well as those coming from far off places to ply in and out of the processing area. 10% of the same has been assumed for working out the total passenger traffic inside EMC.

Along with the employees stay facilities planned within the project site, its allied infrastructures like, primary health centre, nursery/crèche, local shopping centre, restaurant etc., are also provided within the EMC non-processing area towards the entrance/exit area.

Estimated Passenger Trips per day for Processing Area

The estimated passenger trips attracted to processing area is sum of passengers generated outside EMC, passengers generated from non-processing area and the trips made by the family members (educational trips or personal trips) living inside EMC area.

Based on the number of employment and modal split, the total passenger traffic generated / attracted in each sector is estimated.

Employees from far off places (outside EMC) and employees from non-processing area are separately estimated. At the entry/exit location, only the employees residing outside EMC and those family members plying out of EMC from the non-processing zones will be taken into account for checking lane adequacy.

P.1.1.1.3 Total Generated Traffic

The total generated traffic and peak hour traffic in processing area including the goods and passenger traffic is presented in Table P-8.

P.1.1.2 Trip Distribution and Lane adequacy

There is only one primary entry / exit provided for the whole of EMC area through which the total goods traffic and the passenger traffic from outside EMC will enter / exit the area. In order to calculate lane adequacy, traffic per day is calculated for further analysis.

The passenger traffic generated from non-processing area will enter / exit the processing area through the same road network provided for those coming from outside of EMC.

The estimated combined total traffic generated, includes total truck trips generated during peak flow, total passenger trips generated by work force from inside and outside of EMC as well as the passenger trips generated by the family members of the employees residing inside the EMC. The estimated peak hour traffic is distributed in the internal road network, to check the lane requirements.

Peak hour traffic for goods vehicle was assumed to be 15%, passenger vehicles as 40% and family trips were assumed to be 50%. The network adequacy of internal roads is checked with a maximum capacity of 1200 PCU/lane/hr.

The total internal road network has been divided into 28 sections as shown in Figure P-1 and the lane requirement for the same was checked at each section.

Figure P-1: Sections – Internal Road Network

The section wise lane requirements for the expected peak hour traffic generated for the future are given in Table P-9.

Note: Please refer above figure for section number.

As per the typical road sections provided in the proposed plan, 45 m, 30 m and 18 m wide RoW roads are given to have 4 lanes (for 45 m and 30 m) and 2 lane for 18 m roads. Table 2-35 provides the required number of lanes and the proposed number of lanes as per master plan and the remarks stating whether the proposed number of lanes is adequate or not.

It has been observed that the proposed number of lanes is adequate for all the sections when compared to the required number of lanes for the future generated traffic.

P.1.2 Parking

Based on the total truck traffic and chartered buses plying inside and considering the area required for parking of a single truck, the total parking area required for the processing area is estimated and presented in Table P-10.
