Temperature Limit for discharge of Condenser Cooling Water from Thermal Power plant
A. New thermal power plants commissioned after June 1, 1999.
New thermal power plants, which will be using water from rivers/lakes/reservoirs, shall install cooling
towers irrespective of location and capacity. Thermal power plants which will use sea water for cooling
purposes, the condition below will apply.
B. New projects in coastal areas using sea water
The thermal power plants using sea water should adopt suitable system to reduce water temperature
at the final discharge point so that the resultant rise in the temperature of receiving water does not
Rise in temperature of condenser cooling water from inlet to the outlet of condenser shall not be more
than
10o C.
D. Guidelines for discharge point:
1. The discharge point shall preferably by located at the bottom of the water body at mid-stream
for proper dispersion of thermal discharge.
2. In case of discharge of cooling water into sea, proper marine outfall shall be designed to
achieve the prescribed standards. The point of discharge may be selected in consultation with
concerned State Authorities/NIO.
3. No cooling water discharge shall be permitted in estuaries or near ecologically sensitive areas
such as mangroves, coral reefs/spawning and breeding grounds of aquatic flora and fauna.
(ii) Emission Standards
Power generation capacity (MW)
Particulate matter emission
Less than 210 MW
350 mg/Nm3
210 MW or more
150 mg/Nm3
Note:
Depending upon the requirement of local situations, which may warrant stricter standards as in case of
protected areas the State Pollution Control Board and other implementing agencies within the
provisions of the EPA, 1980 may prescribe limit of 150 mg/Nm3 irrespective of the generation capacity
of the plant.
Andhra Pradesh Pollution Control Board and Delhi Pollution Control Committees have stipulated
stringent standards of 115 and 50 mg/Nm3 respectively for control of particulate matter emission.
(iii) Stack Height Requirement
In order to proper dispersion of SO2 emissions from thermal power plants, stack height criteria have
been adopted in the country. However, for larger capacities of boilers (500 m and above), space
provision for installing FGD system has been recommended;
Power generation capacity
Stack height (metre)
Less than 200/210 MW
H = 14(Q) 0.3
where Q is emission rate of SO2 in kg/hr,
H = Stack height in metre
200/210 MW or less than 500 MW
220
500 MW and above
275
Note :
The power plants sanctioned by CEA earlier to July 1, 1994 may not be required to increase existing
stack height as per regulation notified, vide Government of India notification no. GSR 742(E) dated
August 30, 1990 subject to following conditions:
• The ambient sulphur dioxide and NOx concentrations around the power plant is less than 1/3 th
prescribed ambient air quality standard for SO2 and Nox for the concerned area.
• For (1) the power plant shall install adequate number of air quality monitoring stations in and around
the power stations. The stations should be selected in consultation with the CPCB/SPCB.
( Vide office Memorandum No B-34011/1/01/PCI-II dated January 10, 1996 )
(iv) Use of beneficiated coal
In order to minimize flyash generation, it was recommended to use beneficiated coal in the power
plants. The Ministry of Environment & Forests, Govt. of India has promulgated Gazette Notification
(GSR 560(E) & 378(E), dated September 19, 1997 and June 30, 1998 respectively) on use of
beneficiated/blended coal containing ash not more than 34 percent w.e.f. June 2002 in the following
power plants :
• any thermal power plant located beyond one thousand kilometers from the pit-head and
• any thermal power plant located in urban area or sensitive area or critically polluted area irrespective
of their distance from pit-head except any pit-head power plant”.
The power plants using FBC( CFBC,PFBC & AFBC) and IGCC combustion technologies are exempted
to use beneficiated coal irrespective of their locations.
(v) Utilisation of Flyash
In order to make mondatory use of flyash and flyash based products by the brick kilns, Thermal Power
Stations and CPWD& State PWDs , vide notification no. S.O. 763(E) dated September 14, 1999,
Ministry of Environment & Forests has issued directions under sub-rule 3 of rule 5 of EPA, 1986 that
• No person, located within 50 km radius of any Thermal Power Station, shall to manufacture clay
bricks, tiles or blocks without mixing atleast 25% flyash or pond ash with soil.
• Thermal Power Plants shall submit action plan for hundred percent utilization.
New Plants
30% within three yrs
100% within 9 yrs
Existing Plants
20% within three yrs
100% within 15 yrs
Existing notification on utilisation of flyash was amended vide notification no S.O. 979(E) , dated
August 27, 2003 .by Ministry of Environment & Forests incorporating
• No person shall within a radius of 100 kms from thermal power plants, manufacture clay bricks, tiles
or blocks without mixing atleast 25% of flyash or pond ash with soil.
• Every construction Agency including private sector builders within a radius of fifty to one hundred
kilometers from coal or lignite based thermal power plant shall use minimum of following percentage of
ash based products such as: bricks, block & tiles in their construction work:
25% by 31 st August, 2004
50% by 31 st August, 2005
75% by 31 st August, 2006
100% by 31 st August, 2007
In respect of construction of buildings within a radius of fifty kilometers from coal or lignite based
thermal power plant the following minimum percentage of use of bricks, blocks and tiles shall apply:
75% by 31 st August, 2004
100% by 31 st August, 2005
• Authority sanctioning or renewing mining lease shall not grant or extend the lease if the manufacturer
does not use the 25% of the Flyash in the manufacturing of bricks, blocks and tiles.
• Utilisation of Flyash for reclamation of sea subject to compliance of the rules made under the EPA,
1986.
B: Gas/Naptha based Thermal Power Plants
