Subject: Enhancing coal handling capacity, installation of coal conveyor,
stack yard and FDG disposal at Trombay Thermal Power Station,
Maharashtra by MIs Tata Power Company Ltd. - CRZ Clearance Reg.
Sir,
This has reference to your proposal forwarded by the Member Secretary,
Maharashtra Coastal Zone Management Authority (MCZMA)vide letter no. CRZ
2012jCRj288jTC
3 dated 22.05.2014
and your letters dated 06.09.2014
and
11.12.2014 seeking prior CRZ Clearance on the above-mentioned project.
2.
The Ministry of Environment, Forest & Climate Change has considered the
application. It is noted that the proposal is for grant of CRZ Clearance for
enhancing coal handling capacity, installation of coal conveyor,' stack yard
and FDG disposal at Trombay Thermal Power"Station, Maharashtra by MIs
Tata Power Co. Ltd. The proposal was considered by the Expert Appraisal
Committee (EAC)in its meetings held from 30th June, 2014 to 2nd July, 2014, 29th
September to 1st October, 2014 and on 28th - 30th January, 2015. The proponent
has informed that:
The proposal involves import of coal with low sulphur for modernization of
existing Unit #6 by change of fuel to use low sulphur imported coal
(sourced from outside India) in place of LSHSjLSWR.
11. Considering Gross Calorific Value (GCV)of 5000
Kcalj kg of fuel coal, the
coal requirement for Unit #6 is expected to be 6000 TPD. Annual
requirement is estimated to be 2.0 Million MT.
,
111. TTPS has its own captive coal berth facility for handling and unloading of
coal for other units at Trombay. The captive coal berth has installed
unloading capacity of 2.4 million Metric Tonne (MT) per year, which is
proposed to be suitably augmented with additional equipment to unload
coal. This will increase the coal unloading and handling capacity of the
Captive Coal Berth from 2.4 Million MTj year to 4.4 Million MTj year.
Additional coal storage facility will be created next to the coal berth for
storing coal up to 2 Lakh MT. The facility will be supported with the
mechanized coal handling system to handle coal in an environment friendly
manner with constant spraying of water. The existing coal berth will be

optimally utilized with additional equipment without increase in the length
of berth.
To avoid any coal particles getting entrained in air, two coal conveyors are
proposed from the captive coal berth to the Unit #6 for feeding the coal from
the West side of the power Plant. The coal conveyor will be partially of belt
type and partially pipe type with the proper covering arrangement to avoid
dust emission.
All existing system of captive coal berth will be utilized during the proposed
modernization and there is no anticipation of any additional construction
except installation of equipments for coal unloading such as additional coal
unloader for enhancing coal unloading capacity, stacker reclaimer and
conveying system. Since the existing plant shall be used with current lay
out with minimal disturbance through optimum use of facilities, additional
land requirement is not envisaged.
Presently Unit #6 requires 66,000 m-' jhr of sea water for condenser cooling
which is taken from the Thane Creek. It has been estimated that there will
not be any change in the water requirement.
The sea water from the outlet of Unit # 6 Condenser will be sourced and
supplied to the FGD scrubber through the FGD sea water supply pumps.
The sea water, after scrubbing the flue gas within the scrubber tower, will
flow back to the FGD aeration basin by gravity wherein, additional air, by
aeration fans will be mixed with the scrubber effluent to convert the
dissolved Sulphur dioxide in the form of Sulphite to Sulphate.
After the aeration basin, the effluent will be mixed with additional sea water
from the condenser outlet in the dilution basin to dilute the Sulphate
content and to further increase the overall dissolved oxygen (DO) in the
effluent to meet the parameters laid down in the Consent to Establish
accorded by MPCB.
After conforming the standards, the effluent will be discharged into the
existing cooling water outlet channel through an outfall structure of
boulders. This will ensure additional surface area for further cooling and
provide aeration surface to the sea water before passing in to the main
cooling channel.
Main outfall channel ensures additional temperature drop before it is
discharged to the receiving water body (Thane Creek). Additional sea water
from condenser cooling system of units 5,7 and 8 will also be getting mixed
with the unit 6 discharge.
The net estimated increase in the Sulphate concentration of condenser
cooling sea water on dilution by total quantity of 60,000 m3jhr will be 1 %
of baseline sea water concentration of Sulphates (2000 -3500 ppm). This
process is already proven to be effective and environment friendly as the
sulphate is already present in sea water.
This minor increase in Sulphate concentration will be effectively diluted
and dispersed within a short distance after it meets the receiving water
body. Considering the very low relative increase in the sulphate
concentration there will not be any impact on the marine environment.
The temperature measurement at the surface form the discharge point
shows that the ambient temperature is achieved at a distance of 700m
towards west side and 100m in east direction and about 1100m in south
direction. Similar results were obtained for temperature at 1m depth during
low and high tide. Similarly, the pH variation is found to be minimal in the
sea water owing to its high buffer capacity.
