1. the waste wafers and gases are to be treated with the best available technology (BPT) fa. order to achieve the prescribed standards. ~
2. t&e industries need to be encouraged fcjr 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 biotas, energy and reusable materials.
4. while permitting the, discharge of eflhients and emissions into the environment. State Boards have to itake 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 effected, discharges • should not be allowed into water bodies.
5. the Central arid 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. AS ^ffbrts should be made to remove colour and unpleasant odour as fax as practicable.
7. The standards mentioned it^Uiis Schedule shall apply to all the 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 fa) Cell house, (b) Brine plant, (c) Chlorine handling, (d) hydrogen handling and (e) hydro chloric acid plant. P. In case of effluent' containing.biodegradable organic matter without toxic chemicals and pathojeens, namely, -fisrtsentation industry ^ijsSfleries, maltries and breweries), sugar units, dairy plants and food and fruit prc* cessing units :
(a) Limit of 500 mgjl 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 characteriestics. The approval,, of the concerned State Board is necessary prior to adopting this system.
(b) The drainage water from *he land after the secondary "treatment system, as mentioned in the not© 9 (a) has to conform to the limit of 30 mg|l of BOD and 10Mg|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 than 10 mg)l.
(d) The BOD level may be raised upto 790 mg'l for land application as a secondary treatment system, considering hydraulic loading and other soil characteristics, if regular and careful monitoring oS runoff 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 t<k land treatment.
(f) In case of distilleries, sugar, dairy, and food & fruit processing industries, adopting primary treated effluent fr ferti-irrigation in the experimental stage, they have to adopt bic-digeaters for recovery of methane gas as primary treatment prior to its use for ferti-irrigation.
10. All effluents discharged including from tbfi industries such as cotton textile, composite woollen mills, synthetic rubber, small pulp & paper, natural rubber, petro-chemicab, tanneries, paint, dyes, slaughter houses, food & fruit processing and dairy industdies into surface waters shall conform to the BOD limit specified above, namely, 30 rngfl. For discharge of an efihien1. having a BOD more than 30 mgil, the standards shall conform to those given above for other receiving bodies, namely, sewers, coastal waters and land for irrigation. 11 Bio-assay shall be made compulsory for all the industries, where toxic and non-biodegradable chemicals sie involved. 12, In case of fertilizer "industry the limits in respect of chromium and flouride s&»8 be complied with at the cutlet of cfiromium and flouride 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 mt with the available species of fish in the receiving water,-the COD, lirnfts to be specked in the consent condftfOnTshouId be correlated with the BOD limits. 21
(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 waste water by advanced analytical methods such as GLC|HPLC. ANNEXURE-H (For the purpose of part D) The States Boards shall follow the following guidelines in enforcing the standards specified under Schedule VJ :—

(f) In case of asbestos dust, the same shall not exceed 2mg|NM3.
(g) In case of the urea plants commissioned after 1-1-82, coke ovens and lead glass units, the PM emission shall be within 50 mg|NM3.

(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 a cluster should be less than 600 micrograms|NM3. The measurements are to be conducted atleast twice a month for all the 12 months; in a year. These units must also adopt the following pollution control measures :—
(i) Dust containment cum suppression system for the equipment;
(it) 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 a green belt along the periphery.
(k) In case of Ceramic industry, from the other sources of pollution, such as basic raw mate • rial and processing operations, heat recovery dryers, mechanical finishing operation, all possible preventive measures should be taken to control PM emissions as far as practicable.
