Subject :- Modernisation-cum-Expansion of Panki Fertiliser Plant at Kanpur by M/s
Duncans Industries Ltd. Env. Clearance.
This has reference to letter of 25th July, 1996 and subsequent letters of 7th August,
1996, 25th October, 1996 and 30th June, 1997 regarding your application fr modernisation
and capacity augmentation of the existing Panki Fertiliser Plant at Kanpur. The MOE&F
has carefully examined your application. It is observed that on modernisation the
capacities of ammonia and urea plants will be enhanced from 1245 TPD to 1560 TPD and
2046 TPD to 2730, TPD respectively.. It is also noted that on modernisation the existing
coal based captive power plant (12.5 MW) will be discontinued and a new 70.0 MW co-generation Captive Power Plant (GTG and HRSG)based on Naphtha as fuel will be
installed. Further, NOC from the U.P State Pollution Control Board has been obtained for
the above proposal.
2. The Ministry of Environment & Forests hereby accord environmental clearance
subject to strict compliance of the terms and conditions mentioned below:-
The project authorities must adhere to the stipulations made by the U.P. Pollution
Control Board and the State Government.
No expansion of modifications in the plant should be carried out without prior
approval of the Ministry of Environment and Forests.
The particulate matter and gaseous emissions (SO, NOx, NH and HC) from various
processes/units/storages should conform to the standards prescribed by the concerned
authorities from time to time. Urea dust from the prilling tower should not exceed 50 mg/nm
or 0.5 kg/tonne of product. At no time, the emissions should go beyond the prescribed
standards. In the even of failure of any pollution control system adopted by the units, the
respective unit should be immediately put out of operation and should not be restarted until
the control measures are rectified to achieve the desired efficiency.
Ambient air quality monitoring stations should be set up in the down wind direction
as well as where maximum ground level concentration of SPM, SOM NOx, NH and HC are
anticipated in consultation with the State Pollution Control Board.
The air quality monitoring stations should be selected on the basis of mathematical
modelling to represent short-term ground level concentration, human settlements, sensitive
Port holes and sampling facilities should be provided for the stacks as per the
Central Pollution Control Board guidelines. Stack emissions should be monitors in
consultation with the State Pollution Control Board.
Data on ambient air quality and stack emissions should be submitted to this Ministry
once in six months and the State Pollution Control Board once in three months.
Ammonia gas leakage from storages and loading points should be efficiently
controlled or collected and scrubbed or may be sent to incinerator for flaring in
consultation with SPCB.
Adequate precautions for handling ammonia vapours in case of emergency
situation arising due to closure of the plant should be taken.
Fugitive emission should be controlled, regularly monitored and data recorded.
Automatic monitors for ammonia should be provided at appropriate planes in the plant.
Low NOx burners should be used to limit NOx emissions.
The total water requirement should be maintained at 3.7 MGD. Any additional water
requirement should be met through various water conservation schemes as indicated in
Industry should provide separate outlets for storm water, waste waters and process
effluents. Waste waters from the raw water treatment plant, D.M. Plant, Cooling tower the
boiler blow down floor washing spillages and canteen wastes should not be allowed to mix
up with the ammonia and urea plant effluents. The contaminated effluent from ammonia
plant should be subject to solar evaporation in the scientifically designed solar evaporation
pond. The contaminated effluent from urea plant should be stripped in the hydrolyser and
stored in a holding pond and reused/recycled for use as BFW/CW
Oil bearing waste water should be treated for removal of oily matter before
discharge and oil traps should be properly maintained so that the effluent conforms to the
Final effluent quality should conform to the MINAS. The treated waste water should
be recycled and used for irrigation to the extent feasible.
Guard ponds of sufficient holding capacity should be provided to cope up with the
effluent discharge during the process disturbances. The contributing units should be
immediately shut down and should not be restarted without bringing the system back to
The solar evaporation pond, guard ponds and holding ponds should be provided with
impervious lining and stability of the ponds with respect to leakages/cracks and other
factors should be ensured.
The ground water quality around the solar evaporation, guard ponds, holding
ponds, landfill site and areas irrigation with treated effluent should be monitored on a
regular bases. The monitored dates should be submitted to the Ministry (Regional Office,
Lucknow) once in six months and to the SPCB and State Ground Water Board once in
Adequate number of influent and effluent quality monitoring stations should be set
up in consultation with the State Pollution Control Board. Regular monitoring should be
carried out for relevant parameters. Routine toxicity test of effluent with fish should also
be regularly done. Monitored data in the form of a report should be submitted to this
Ministry (Regional Office, Lucknow) once in six months and the State Pollution Control
Board once in three months.
The industry should provide a purge gas recovery unit for removing ammonia, H
and CH instead of burning in the primary reformer.
The hazardous wastes should be handled as per the Hazardous Waste (Management
& handling) Rules, 1989 of the Environment (Protection) Act, 1986, Permission of State
Pollution Control Bard must be obtained for its management and disposal.
Handling, manufacture, storage and transportation of hazardous chemicals should
be in accordance with the Manufacture, Storage and Import of Hazardous Chemicals
Rules, 1989 as amended in October, 1994.
Adequate measures for the control of noise should be taken so as to keep the noise
levels below 85 dB in the work environment. Persons working near the noisy machines like
ammonia plant, urea plant, TG, Compressor room, etc. should be provided with well
designed ear muffs/plugs.
Non-chromate system should be used in all the cooling towers. As zinc in also being
to be used with non-chromate dozing, its level in blow-down and sludge should be kept
below the prescribed standards.
Suitable alarm system and standard procedure for transmitting the information on
the occupance of an accident to the proper focal point should be established. Steps should
also be taken to ensure access to information on weather conditions prevailing at that time
and weather forecast. Wind socks at appropriate locations should be provided.
Graphs/nomograms indicating spatial distribution of concentrations of toxic gas during
day and night under different stability classes and wind conditions so as to help the
designated Emergency Offices/Team to organise rescue operations in case of accidental
release of toxic gasses/vapours.
Efforts should be made to increase green belt all around the fertilizer complex and
the township. Native plant species should be selected for this purpose in consultation with
the local DFO. A green belt development plant to cover at least 25% area maybe
submitted for approval within 3 months.
The project authorities should set up laboratory facilities for collection and analysis
of samples under supervision of competent technical personnel, who will directly report to
the Chief Executive.
A separate environmental management cell with suitably qualified people to carry
out various functions should be set up under the control of a senior Executive who will
report directly to the head of the organisation.
Periodical medical check up of the workers should be done and records maintained.
The funds earmarked for the environmental protection measures should be kept in
separate account and should not be diverted for other purposes and year wise expenditure
should be reported to this Ministry and to the State Pollution Control Board under the rules
prescribed for environmental audit.
3. The Ministry reserve the right to revoke the clearance if implementation of any of
the condition stipulated by this ministry or any other competent authorities is not
satisfactory. Six monthly status report on project vis-a-vis implementation of environmental
measures should be submitted to Ministry and its Regional Office, Lucknow/CPCB/ the
4. The Ministry reserves the right to stipulate additional conditions or alter the existing
conditions if found necessary. These will be fully implemented by the project authorities
in a time bound manner.
5. The above conditions will be implemented under the provisions of the Water
(Prevention and Control) of Pollution Act, 1974, the Air (Prevention and Control) of
Pollution Act, 1981, Environment (Protection) Act, 1986 and the Public (Liability) Act, 1991
