                                                                 Tamnar, District Raigarh (CG)
                                                                          Jindal Power Limited

      HCFC free refrigerants and chillers, solar water heaters on major buildings are some
      recommended energy saving devices that should be considered in this project.

2.    Energy efficient building materials should be considered for construction of
      structures. For external walls and boundary wall flyash bricks and blocks should be
      considered. Flyash, which is a waste of power plant should be mixed with cement to
      make concrete. Rat trap cavity brickwork using flyash bricks / blocks should be
      considered. Thermally insulated building roof through traditional methods of brick
      batcoba technique / other recommended technique should be considered. Natural
      ventilation system comprising screen walls, low emissive double glazed glass with U
      value of less than 2.8 W/m2K, shading coefficient of 0.5 should be considered for the
      buildings. Fenestration with UPVC framing that reduces solar heat gain should be
      considered. Landscaping with deciduous tree canopy should be considered for
      reducing heat gain into the structures (by blocking sun rays in summer and permitting
      penetration during winter).

3.    Energy efficient process and building structures should achieve 20% reductions in
      energy consumption. It is recommended that the project authorities should undertake
      yearly energy audit for their entire manufacturing process and ancillary facilities. PIL
      should also avail the benefits under CDM or carbon credit, as per applicable rules
      framed by the International Panel on Climate Change.

5.7     Budget for EMP

The capital cost for environmental management of the proposed power plant is estimated
to be Rs.407 crores. Budget allocation of Rs.34.0 crores will be made every year to meet
the recurring expenditure for implementing the environmental control and improvement
measures. The details are given below.

6.1       Consequence Analysis

Thorough examination of the preliminary TEFR of facilities and P&I, together with
consultation with JSL, all accident or spill scenarios has been identified that could result in
environmental consequences. Following scenarios feel under Maximum Credible Accident

      •   Fire due to spill of 4000 KL LDO storage tank
      •   Fire in coal yard and gallery
      •   Leakage in acid / alkali storage tank near DM Plant
      •   Injury to body and body parts (mechanical)

a) Fire in Fuel Tanks: Light Diesel Oil is viscous mixture of aromatic hydrocarbons with
flash point and auto ignition point higher than naphtha, petrol and kerosene. It is flammable
and needs source of ignition to catch fire. Its vapour pressure is also higher than its other
counterparts. Hence, fire risk due to storage and handling of LDO is less compared to
naphtha or petrol. LDO has boiling point above the ambient temperature and therefore
stored in tanks under normal atmospheric pressure and temperature. Continuous release
of such non-boiling liquids from vessels due to leaks will form a contained pool inside the
dyke area of the Tank. Upon ignition the liquid pool will result in pool fire. In case of ignition
of the hydrocarbon vapour-air mixture present near rim seals and rim vents of storage
tanks, tank fire will result in tank fire. Pool fire and Tank fire falls under MCA scenario. The
heat radiation effect distances for the largest tank combination are described below.

1st degree burn - 4.0 KW/m2
1% fatality - 12.7 KW/m2 for 20 seconds exposure [EIA manual of MOEF prescribes
thermal limit of 12.7 for 20 seconds exposure]
50% fatality - 25.0 KW/m2
99%fatality - 37.5 KW/m2

The following assumptions have been considered during modeling:

      1. Steady state burning has been assumed.
      2. A surface radiation flux of 120 KW/m2
