ANNEXURE-I (For the purposes of Parts-A, B and
C)
The State Boards shall follow the following guidelines
in enforcing the standards specified under schedule
VI:-
1. The wastewaters and gases are to be treated with
the best available technology (BAT) in order to achieve
the prescribed
standards. 2. The industries
need to be encouraged for recycling and reuse of waste materials as far as
practicable in order to minimise the discharge of wastes
into the environment. 3. The industries
are to be encouraged for recovery of biogas, energy and reusable
materials. 4. While permitting
the discharge of effluents and emissions into the environment, State
Boards have to take into account the assimilative capacities of
the receiving bodies, especially water bodies so that quality of
the
intended use of the receiving waters is not affected. Where such quality
is likely to be affected, discharges should not be allowed into water
bodies. 5. The Central and
State Boards shall put emphasis on the implementation of clean
technologies by the industries in order to increase fuel efficiency and
reduce the generation of environmental pollutants.
6. All efforts should be made to remove colour and
unpleasant odour as far as practicable. 7. The
standards mentioned in this Schedule shall also apply to all other
effluents discharged such as industrial mining, and mineral processing
activities and sewage. 8. The limit given
for the total concentration of mercury in the final effluent of caustic
soda industry, is for the combined effluent from (a) Cell
house, (b) Brine plant, (c) Chlorine handling, (d) hydrogen handling and
(e) hydro
chloric acid plant. 9. In case of
effluent containing biodegradable organic matter without toxic chemicals
and pathogens, namely, fermentation industry
(distilleries, maltries and breweries), sugar units, dairy plants and food
and fruit
processing units:
(a) Limit of 500 mg/l is entitled only in
case the land application is envisaged as a secondary treatment
system for further
removal of BOD. It is to be noted that controlled and properly designed
land treatment system has to be
adopted for this purpose taking into account soil and crop
characteristics. The approval of the concerned
State Board is necessary prior to adopting this
system. (b) The
drainage water from the land after the secondary treatment system, as
mentioned in note 9(a) has to conform to
the limit of 30 mg/l of BOD and 10 mg/l of Nitrate expressed as
`N'. (c) The
net addition to the ground water quality should not have a BOD more than
30 mg/l and Nitrate expressed as `N' more
than10 mg/l. (d) The
BOD level may be raised upto 700 mg/l for land application as a secondary
treatment system, considering
hydraulic loading and other soil characteristics, if regular and careful
monitoring of run-off and leachate
satisfies the concerned State Pollution Control Boards that the BOD level
higher than 500 mg/l can be allowed
in the effluent. (e)
Where land application as secondary treatment system is adopted employing
higher BOD in the treated effluent,
domestic waste should be excluded from the effluent or disinfection should
form a part of the treatment
prior to application of the same for land treatment.
(f) In case of distilleries, sugar,
dairy, and food & fruit processing industries, adopting primary
treated effluent for
ferti-irrigation in the experimental stage, they have to adopt
bio-digesters for recovery of methane gas as
primary
treatment prior to its use for ferti-irrigation.
10. All effluents discharged including from the
industries such as cotton textile, composite woolen mills,
synthetic rubber, small pulp &
paper, natural rubber, petrochemicals, tanneries, paint,dyes, slaughter
houses, food & fruit processing and diary
industries into surface waters shall conform to the BOD limit specified
above, namely, 30 mg/l. For
discharge of an effluent having a BOD more than 30 mg/l, the standards
shall conform to those given above for
other receiving bodies, namely, sewers,coastal waters and land for
irrigation.
11.1[***]
12. In case of fertilizer industry the limits in
respect of chromium and fluoride shall be complied with at the
outlet of chromium and fluoride
removal units, respectively.
13. In case of pesticides:
(a) The limits should be complied
with at the end of the treatment plant before
dilution.
(b) Bio-assay test should be carried out with the available species of
fish in the receiving water, the COD limits to be
specified in the consent conditions should be correlated with the BOD
limits.
(c) In case metabolites and isomers of the Pesticides in the given list
are found in significant concentrations, standards
should be prescribed for these also in the same concentration as the
individual pesticides.
(d) Industries are required to analyse pesticides in wastewater by
advanced analytical methods such as
GLC/HPLC.
14. The chemical oxygen demand (COD) concentration in
a treated effluent, if observed to be persistently
greater than 250 mg/l before
disposal to any receiving body (public sewer, land for irrigation, inland
surface water and marine coastal areas),
such industrial units are required to identify chemicals causing the same.
In case these are found to be
toxic as defined in the Schedule-I of the Hazardous Rules, 1989, the State
Boards in such cases shall direct the
industries to install tertiary treatment stipulating time
limit.
15. Standards specified in Part A of Schedule-VI for
discharge of effluents into the public sewer shall be
applicable only if such sewer leads to a
secondary treatment including biological treatment system, otherwise
the discharge into sewers shall
be treated as discharge into inland surface waters.

G.S.R.801(E) dated 31.12.1993.
ANNEXURE-II (For the purpose of
Part-D)The States Boards shall follow the following
guidelines in enforcing the standards specified under Schedule
VI:
(a) In case of cement plants, the total dust (from all
sections) shall be within 400 mg/Nm3 and
250 mg/Nm3 for
the plants upto 200 t/d and more
than 200 t/d capacities, respectively. (b) In
respect of calcination process (e.g. Aluminium Plants) Kilns and step
Grate Bagasse fired-Boilers, Particulate Matter (PM)
emissions shall be within 250 mg/Nm3. (c) In
case of thermal power plants commissioned prior to 1-1-1982 and having
generation capacity less than 62.5 MW, the PM emission shall be
within 350 mg/Nm3. (d) In
case of Lime Kilns of capacity more than 5t/day and upto 40t/day, the PM
emission shall be within 500 mg/Nm3. (e) In
case of horse shoe/pulsating Grate and Spreader Stroker
Bagasse-fired-Boilers, the PM emission shall be
within 500 (12% CO2) and 800 (12% CO2) mg/Nm3,
respectively. In respect of these boilers, if more
than
attached to a single stack, the emission standard shall be fixed, based on
added capacity of all the boilers connected with the
stack. (f) In case of
asbestos dust, the same shall not exceed 2 mg/Nm3 (g) In
case of the urea plants commissioned after 1-1-92, coke ovens and lead
glass units, the PM emission shall be within 50 mg/Nm3. (h) In
case of small boilers of capacity less than 2 tons/hr and between 2 to 5
tons/hr, the PM emissions shall be within 1000 and 1200 mg/Nm3. (i) In
case of integrated Iron and Steel Plants, PM emission upto 400 mg/Nm3 shall be allowed during
oxygen
lancing. (j) In case of stone
crushing units, the suspended PM contribution value at a distance of 40
meters from a
controlled, isolated as well as from a unit located in cluster should be
less than 600 micrograms/Nm3. 1[* *
*] These units must also adopt the
following pollution control measures:- (i) Dust containment cum
suppression system for the equipment; (ii) Construction of wind breaking
walls;
(iii) Construction of the metalled roads within the
premises;
(iv) Regular cleaning and wetting of the ground within the
premises;
(v) Growing of green belt along the periphery.
(k) In case of Ceramic industry, from the other
sources of pollution, such as basic raw material and
processing
operations, heat recovery dryers, mechanical finishing operation, all
possible preventive measures should be taken to control PM emission as far
as practicable.
2. The total fluoride emission in respect of Glass and
Phosphatic Fertilizers shall not exceed 5 mg/NM3 and 25 mg/NM3, respectively. 3. In
case of copper, lead and zinc smelting, the off-gases may, as far as
possible, be utilised for manufacturing sulphuric acid
4. In case of cupolas (Foundries) having capacity
(melting rate) less than 3 tonne/hour, the particulate
matter
emissions shall be within 450 mg/Nm3. In
these cases it is essential that stack is constructed over the
cupolas beyond
the charging door and the emissions are directed through the stack, which
should be atleast six times the diameter of cupola. In respect of Arc
Furnaces and Induction Furnaces, provision has to be made
for
collecting the fumes before discharging the emission through the
stack.
