Charter
on Corporate Responsibility for Environment Protection (CREP)
The Central Pollution Control Board has prepared a Charter on Corporate Responsibility for Environment Protection (CREP) for the Fertiliser Industry. The charter will be discussed during a Technical Meeting and will be presented at a National Level Seminar organised by CPCB/MoEF. The exact dates of the Meeting and Seminar are yet to be announced.
Charter on
Corporate Responsibility for Environment Protection (CREP)
Action
Points :
1. Efforts
will be made for conservation of water, particularly with a target to have
consumption of water less than 8, 12 and 15 m3/tonne of urea produced
for plants based on gas, naphtha and fuel oil respectively. An action plan for this will be
submitted by June 2003 and targets will be achieved by March 2004.
2. Use of
arsenic for CO2 absorption in ammonia plants and chromate based
chemicals for cooling systems, which is still continuing in some industries,
will be phased out and replaced with non-arsenic and non-chromate systems by
December 2003. In this regard,
action plan will be submitted by March 2003.
3.
Adequate treatment for removal of oil, chromium (till non-chromate based
cooling system is in place) and fluoride will be provided to meet the prescribed
standards at the source (end of respective process unit) itself. Action plan
will be firmed up by June 2003 for compliance by March 2004.
4. Proper and
complete nitrification and de-nitrification will be ensured, wherever such
process is used for effluent treatment,
by September 2003.
5.
Groundwater monitoring around the storage facilities and beyond the
factory premises will be carried out at regular intervals particularly for pH,
nitrate and fluoride. CPCB will
finalize the guidelines for groundwater monitoring by December 2003.
6. No effluent
arising from process plants and associated facilities will be discharged to the
storm water drain. The quality of
storm water will be regularly monitored by all the industries. Industries where
water/effluent flows through the storm water drains even during the dry season
will install continuous systems for monitoring the storm water quality for pH,
ammonia and fluoride. If required, storm water will be routed through effluent
treatment plant before discharging.
An action plan will be submitted by June 2003 and necessary action will
be taken by June 2004.
1.
All the upcoming urea plants will have urea prilling towers based on
natural draft so as to minimize urea dust emissions.
2.
The existing urea plants, particularly, the plants having forced draft
prilling towers, will install appropriate systems (e.g. scrubber, etc.) for
achieving existing norms of urea dust emissions. In this regard, industries will
submit action plan by March 2003 and completion of necessary actions by June
2004.
3. The sulphuric acid
plants having SCSA system will switch over to DCDA system by March 2004 to meet
the emission standard for SO2 as 2 kg/tones of
H2SO4. An
action plan for this will be submitted by March 2003.
4. Sulphuric acid plants
having DCDA system will improve the conversion and absorption efficiencies of
the system as well as scrubbers to achieve SO2 emissions of 2
kg/tonne of acid produced. An
action plan will be submitted by March 2003 and emission levels will be complied
with by September 2004.
5. Stack height for
sulphuric acid plants will be provided as per the guidelines and on the basis of
normal plant operations (and not when the scrubbers are in use) by June 2003.
The scrubbed gases are to be let out at the same height of the stack.
6. An action plan for
providing proper dust control systems at rock phosphate grinding unit in
phosphoric acid plants/single super phosphate plants, so as to achieve
particulate emission levels of 150 mg/Nm3 will be submitted by
September 2003 and complied with by March 2004.
7. Particulate as well as gaseous fluoride
will be monitored and adequate control systems will be installed by June 2004 to
achieve the norms on total fluoride emissions (25 mg/Nm3).
8. Continuous SO2 emission
monitoring systems will be installed in sulphuric acid plants (having capacity
200 tpd and above) by March 2004. Action plan for this will be submitted by
March 2003.
9. Regular monitoring of
ambient air quality with regard to SO2, NOx, PM,
SO3, fluoride and acid mist will be carried out.
Solid waste management
1. Gypsum will be effectively
managed by providing proper lining, dykes with approach roads and monitoring of
groundwater quality around storage facilities. Accumulated gypsum will be properly
capped. In this regard, action plan
will be submitted by June 2003 and for compliance by December 2003.
2.
An action plan for proper disposal of spent catalyst having toxic metals
will be submitted by March 2003 and implemented by September 2003.
3. Carbon slurry, sulphur muck and chalk will be properly managed and disposed of in properly designed landfill. Action plan on this will be submitted by June 2003 and implemented by March 2004.
4.
Existing stock of chromium
and arsenic bearing sludge will be properly disposed of by December 2003.
