Recommendations of Working Group I concerning:

1
PROPOSED CHARTER ON WATER RECYCLING POLLUTION
PREVENTION IN PULP PAPER INDUSTRY

• Recommendations of Working Group I concerning
• Categorization of Industry
• Objectives
• Proposed Norms
• Proposed Sction Points

2
Categories of Indian Pulp Paper Mills

• Proposed Categorization under this Revised
  Charter
• A1 Wood Based Pulp Paper Mills producing
  bleached grades of chemical pulps, papers,
  paperboards newsprint
• A2 Wood Based Pulp Paper Mills producing
  unbleached grades of chemical pulps, papers and
  paperboards
• B1 Agro Based Pulp Paper Mills producing
  bleached grades of chemical pulps, papers,
  paperboards newsprint
• B2 Agro Based Pulp Paper Mills producing
  unbleached grades of papers and paperboards
• C1 RCF and Market Pulp Based Paper Mills
  producing bleached grades of papers, paperboards
  newsprint
• C2 RCF and Market Pulp Based Paper Mills
  producing unbleached grades of papers and
  paperboards
• Mills that attract classification in more than
  one category will be deemed to be in the
  highest among those categories. For example, a
  mill that is both wood and agro based (A1 B1)
  will be classified as A1.

3
Objectives of the Charter

• All time Compliance with Environmental Norms
• This compliance shall be determined by long-term
  performance criteria like a 30-day moving
  average. Besides, allowable Exceedances shall
  be permissible on the basis of an agreed
• of operating time that such exceedances occur
• number of such exceedances per year/month
• by which each such exceedance can deviate from
  norm
• Start-up/shut-down periods, normal boiler
  soot-blowing sequences and exceptional
  circumstances (to be enumerated) should not be
  considered while determining all-time compliance.
• Water consumption, effluent generation and
  emission limits shall be reckoned per tonne of
  product and not just paper. Besides paper,
  paperboard and newsprint, product shall include
  air dry tonnes of surplus pulp produced for short
  term storage (as wet-lap) or for sale.

4
Objectives of the Charter

• Improved Environmental Performance beyond
  Regulatory Norms
• This will essentially be a voluntary effort by
  the mills with performance targets proposed in
  advance, properly documented, and then validated
  by third parties.
• Achievement of such improved performance should
  receive appropriate recognition from CPCB/SPCBs
  and, in particular, should qualify for fast-track
  environmental clearances.

5
Objectives of the Charter

• Increased Productivity
• Freedom to install minimum impact technology
  will not only improve better environmental
  performance but also ensure stakeholder
  relations, increased productivity, cost savings
  and competitive market advantages.
• Constrained by the General and Special
  Conditions imposed by Environmental Clearances
  and Operating Permits, increased productivity
  could only amount to achieving the same
  production levels with lesser specific
  consumption of any or all of the resources
  involved in mill operations.

6
Objectives of the Charter

• Compliance with International Commitments
• Compliance with international commitments in the
  context of environmental regulation of the paper
  industry will be meaningful if effluent discharge
  standards are load based instead of the existing
  concentration based ones. Making ECF bleaching
  mandatory would then be the only residual issue.
• Internationally, ECF bleaching is mandatory (BAT
  standard) and the only wood pulp bleaching
  technology to ensure safe AOx levels.
  Well-managed agro-pulp bleaching could still hold
  AOx levels to that of wood based ECF pulp
  bleaching without eliminating elemental chlorine.
  Indias compliance, in an agro pulping context,
  should be decided only on prescribed AOx levels.
• Elimination of elemental chlorine in existing
  Agro mills, or wood pulp mills of capacity lt200
  tpd, could be either a voluntary initiative or a
  condition for expansion of capacity or
  establishment of new capacities.

Fresh Water Consumption Norms in the Revised
Charter (m3/t of product)
Tentative norms for Mills manufacturing
specialty paper. Wide variation can exist,
determined by grades (Hygiene grades/FDA
grades/coloured grades, etc). Case-to-case
consideration, based on product portfolio, would
be required

Proposed Effluent Generation Norms in the Revised
Charter (m3/t of product)
Tentative norms for Mills manufacturing
specialty paper. Wide variation can exist,
determined by grades (Hygiene grades/FDA
grades/coloured grades, etc). Case-to-case
consideration, based on product portfolio, would
be required

SAR 12 (Short/Medium Term)10 (Long Term)
Deviation from the norms for a specified of the
time in a year (say, 5) should be considered

TSS, mg/l 50
BOD, mg/l lt 30
COD, mg/l 225
TDS, mg/l 2100
SAR 12 (Short/Medium Term)10 (Long Term)
Deviation from the norms for a specified of the
time in a year (say, 5) should be considered
within compliance.
11
Water Consumption Effluent Generation Norms
w.r.t Irrigation Schemes

• Mills that discharge all their treated effluents
  on land for irrigation through dedicated effluent
  distribution schemes have an obligation to
  dependent farmers. These mills will be entitled
  to a relaxation of water consumption and effluent
  generation norms, Such relaxation, to the extent
  required, shall be accorded to eligible mills
  through a validation protocol to be notified by
  CPCB.
• Such relaxation shall, however, be subject to the
  following conditions
• The dedicated irrigation scheme should have been
  in practice for a period of not less than five
  (5) years
• The scheme should have, during this 5-year
  period, used all the effluent generated by the
  mill.
• The effluent load generated by the mill shall
  not be in excess of the norms. In effect, any
  relaxation in volumetric terms would entail a
  corresponding reduction in the concentration
  terms.

12
Proposed Norms for Odorous Emissions
Odorous gases Existing Emission Norms mg/Nm 3 Proposed Emission Norms mg/Nm 3 Measurement Method Control technology
H2S 10 10 Gastec Tube Sampling Alkaline Absorption, Biological Methods, Adsorption, orIncineration (Incineration is proven but involves highest investment operating costs)
Total Mercaptans (Methyl Mercaptan, DMS DMDS) Not Specified 50 Gastec Tube Sampling Alkaline Absorption, Biological Methods, Adsorption, orIncineration (Incineration is proven but involves highest investment operating costs)
Recommended by the Expert Committee on Odour
Polluton its Control constituted by CPCB
Guidelines published May 2008.
These emissions shall be measured twice a year,
as an odour control assessment protocol, to
identify and evaluate point source emissions of
odorous gases. Mills that operate with a Soda
Process and with mill-wide sulphur-free
operations, shall be exempt from this section of
the Charter.
13
Proposed Stack Emission Norms

Boiler Capacity Control Equipmnt Existing Norms (mg/Nm3) Proposed Norms (mg/Nm3) Remarks
15tph above ESP SPM 150 H2S 10 Sox Not Defined Nox Not Defined SPM 150 (Boilers set up before 2008) SPM 100 (Boilers set up after 2008) H2S 10 Norms for a Chemical Recovery Boiler lime kiln will be same as that for a Power Boiler with capacity gt15 tph
For boilers lt15 tph Multi Cyclone SPM 600 (10- 15tph) SPM 800 (lt10 tph) H2S Not Defined SPM 600 H2S 10
NOX SOx has already been notified under
National Ambient Air Quality Standards. H2S
norms will be applicable only to stacks attached
to Chemical Recovery Boilers. Deviation from the
norms for a specified of the time (say, 5)
should be considered within compliance.
14
Conditions Necessary for Timely Compliance with
the Charter

• No regulatory impediments.
• Any process modification, construction activity
  or any other action required to be undertaken by
  a mill in pursuit of the objectives of this
  Charter should receive necessary environmental
  clearances from SPCBs with utmost speed.
  CPCB/MoEF should set in place a fast-track,
  single-window clearance mechanism.
• Zero Liquid Discharge (ZLD) Conditions not to
  apply.
• SPCBs should be advised not to prescribe a ZLD
  condition in any of their operating permits
  during the currency of this Charter. If mills
  were to be capable of achieving ZLD, there would
  be no need for this Charter.
• SPCBs active support, and understanding,
• The transition from Short Term compliance levels
  to the next two levels could entail disruptions
  in mill operations leading to temporary
  aberrations in quality of treated effluents.
