(9) Emission inventory: Refinery shall prepare on inventory of equipment components in the plant. After the instrumental measurement of leaks, emission from the components will be calculated using stratified emission factor (USEPA) or any other superior factors. The total fugitive emission will be established.

(10) Monitoring following types of monitoring methods may be judiciously employed for detection of leaks: (i) instrumental method of measurement of leaks; (ii) Audio, visual and olfactory (AVO) leak detection; and (iii) Soap bubble method.

(11) Data on time of measurement and concentration value for leak detection; time of repair of leak; and time of measurement & concentration value after repair of leak should be documented for all the components.

[114][C. Guidelines for Disposal of Solid Waste, Drill Cutting and Drilling Fluids for Offshore and Onshore Drilling Operation—

1. Disposal of Drill Cutting and Drilling Fluids for On-shore Installations:

(a) Drill Cuttings (DC) originating from on-shore or locations close to shore line and separated from Water Base Mud (WBM) should be properly washed and unusable Drilling Fluids (DF) such as WBM, Oil Base Mud (OBM), Synthetic Base Mud (SBM) should be disposed off in a well designed pit lined with impervious liner located off-site or on-site. The disposal pit should be provided additionally with leachate collection system.

Design aspects of the impervious waste disposal pit; capping of disposal pit should be informed by the oil industry to State Pollution Control Board (SPCB) at the time of obtaining consent.

(b) Use of diesel base mud is prohibited. Only WBM should be used for on-shore oil drilling operations.

(c) In case of any problem due to geological formation for drilling, low toxicity OBM having aromatic content< 1% should be used. If the operators intend to use such OBM to mitigate specific whole problem/SBM it should be intimated to Ministry of Environment and Forests/State Pollution Control Board.

(d) The chemical additives used for the preparation of DF should have low toxicity i.e. 96 hr LC₅₀ > 30,000 mg/l as per mysid toxicity or toxicity test conducted on locally available sensitive sea species. The chemicals used (mainly organic constituents) should be biodegradable.

(e) DC separated from OMB after washing should have oil content at < 10 gm/kg for disposal into disposal pit.

(f) The waste pit after it is filled up shall be covered with impervious liner, over which, a thick layer of native soil with proper top slope is provided.

(g) Low toxicity OBM should be made available at installation during drilling operation.

(h) Drilling wastewater including DC wash water should be collected in the disposal pit evaporated or treated and should comply with the notified standards for on-shore disposal.

(i) Barite used in preparation of DF shall not contain Hg> 1 mg/kg & Cd> 3mg/kg.

(j) Total material acquired for preparation of drill site must be restored after completion of drilling operation leaving no waste material at site. SPCB should be informed about the restoration work.

(k) In case, environmentally acceptable methods for disposal of drill waste such as (a) injection to a formation through casing annuals, if conditions allow (b) land farming at suitable location (c) bio-remediation (d) incineration or (e) solidification can be considered, in such cases oil industry is required to submit proposal to Ministry of Environment and Forests/State Pollution Control Board (MoEF/SPCB) for approval.

2. Disposal of Drill Cutting and Drilling Fluids for Off-shore Installations:

(a) Use of diesel base mud is prohibited. Only WBM is permitted for offshore drilling. If the operator intend to use low toxicity OBM or SBM to mitigate specific hole problems in the formation, it should be intimated to MoEF/SPCB. The low toxicity OBM should have aromatic content< 1%.

(b) The toxicity of chemical additives used in the DF (WBM or OBM or SBM) should be biodegradable (mainly organic constituents) and should have toxicity of 96 hr LC₅₀ Value > 30,000 mg/l as per mysid toxicity or toxicity test conducted on locally available sensitive sea species.

(c) Hexavalent chromium compound should not be used in DF. Alternative chemical in place of chrome lignosulfonate should be used in DF. In case, chrome compound is used, the DF/DC should not be disposed offshore.

(d) Bulk discharge of DF in offshore is prohibited except in emergency situations.

(e) WBM/OBM/SBM should be recycled to a maximum extent. Unusable portion of OBM should not be discharged into sea and shall be brought to on-shore for treatment & disposal in an impervious waste disposal pit.

(f) Thoroughly washed DC separated from WBM/SBM & unusable portion of WBM/SBM having toxicity of 96 hr LC₅₀ > 30, 000 mg/l shall be discharged off-shore into sea intermittently, at an average rate of 50 bbl/hr/well from a platform so as to have proper dilution & dispersion without any adverse impact on marine environment.

(g) Drill cutting of any composition should not be discharged in sensitive areas notified by the Ministry of Environment and Forests.

(h) In case of specific hole problem, use of OBM will be restricted with zero discharge of DC. Zero discharge would include re-injection of the DC into a suitable formation or to bring to shore for proper disposal. In such a case, use of OBM, for re-injection should be recorded and made available to the regulatory agency. Such low toxic OBM having aromatic content < 1% should be made available at the installation.

(i) In case, DC is associated with high oil content from hydrocarbon bearing formation, then disposal of DC should not have oil content > 10gm/kg.

(j) The DC wash water should be treated to confirm limits notified under EPA, before disposal into Sea. The treated effluent should be monitored regularly.

(k) Discharge of DC from the installation located within 5 km away from shore should ensure that there is no adverse impact on marine Ecosystem and on the shore. If, adverse impact is observed, then the industries have to bring the DC on-shore for disposal in an impervious waste disposal pit.

(l) If any, environmental friendly technology emerges for substitution of DF and disposal technology, it may be brought to the notice of MoEF and regulatory agencies. If the operator desire to adopt such environment friendly technology a prior approval from Ministry of Environment and Forests is required.

(m) Barite used in preparation of DF shall not contain Hg > 1 mg/kg & Cd > 3 mg/kg.

(n) Oil drilling operators are required to record daily discharge of DC & DF to offshore and also to monitor daily the effluent quality, and submit the compliance report once in every six-month to Ministry of Environment and Forests.]

86.	Water quality standards for coastal waters marine outfalls.
	In a coastal segment marine water is subjected to several types of uses. Depending on the types of uses and activities, water quality criteria have been specified to determine its suitability for a particular purpose. Among the various types of uses there is one use that demands highest level of water quality/purity and that is termed a “designated best use” in that stretch of the coastal segment. Based on this, primary water quality criteria have been specified for following five designated best uses:—
	Class												Designated best use
	SW-1 (See Table 1.1.)												Salt pans, Shell fishing, Mariculture and ecologically Sensitive Zone.
	SW-II (See Table 1.2)												Bathing, Contact Water Sports and Commercial fishing.
	SW-III (See Table 1.3)												Industrial cooling, Recreation (non-contact) and Aesthetics
	SW-IV (See Table 1.4)												Harbour
	SW-V (See Table 1.5)												Navigation and Controlled Waste Disposal.
	The Standards alongwith rationale/remarks for various parameters for different designated best uses, given in Table 1.1 to 1.5. TABLE 1.1 PRIMARY WATER QUALITY CRITERIA FOR CLASS SW-I WATERS [For Salt Pans, Shell Fishing, Mariculture and Ecologically Sensitive Zone]

	Note.—SW-I is desirable to be safe and relatively free from hazardous, chemicals like pesticides, heavy metals and radionuclide concentrations. Their combined (synergistic or antagonistic) effects on health and aquatic lives are not yet clearly known. These chemicals undergo bio-accumulation, magnification and transfer to human and other animals through food chain. In areas where fisheries, salt pans are the governing considerations, and presence of such chemicals apprehended/reported, bio-assay test should be performed following appropriate methods for the purpose of setting case specific limits.

93. Primary Water Quality Criteria for Bathing Waters.

In a water body or its part, water is subjected to several types of uses. Depending on the types of uses and activities, water quality criteria have been specified to determine its suitability for a particular purpose. Among the various types of uses there is one use that demands highest level of water quality or purity and that is termed as “Designated Best use” in that stretch of water body. Based on this, water quality requirements have been specified for different uses in terms of primary water quality criteria. The primary water quality criteria for bathing water are specified along with the rationale in Table 1.

1.	Fecal Coliform MPN/100 ml:	500 (desirable) 2500 (Maximum	To ensure low sewage contamination. Fecal Coliform and Fecal Streptococci are considered as they reflect the bacterial pathogenicity.
2.	Fecal Streptococci MPN/100 ml:	100 (desirable) 500 (Maximum Permissible)	The desirable and permissible limits are suggested to allow for fluctuation in environmental conditions such as seasonal change, changes in flow conditions etc.
3.	pH:	Between 6.5-8.5	The range provides protection to the skin and delicate organs like eyes, nose, ears etc. which are directly exposed during outdoor bathing.
4.	Dissolved Oxygen	5 mg/l or more	The minimum dissolved oxygen concentration of 5 mg/l ensures reasonable freedom from oxygen consuming organic pollution immediately upstream which is necessary for preventing production of anaerobic gases (obnoxious gases) from sediment.
5.	Biochemical Oxygen demand 3 day, 27^oC:	3 mg/l or less	The Biochemical Oxygen Demand of 3mg/l or less of the water ensures reasonable freedom from oxygen demanding pollutants and prevent production of obnoxious gases.]

ANNEXURE - I

(For the purposes of Parts-A, B and C)

The State Boards shall follow the following guidelines in enforcing the standard specified under Schedule VI:

1. The waste waters 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 minimize 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 emission 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 water is not affected. Where such quality is likely to be effected 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 [228][shall also apply to all other [effluents] discharged such as] 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) hydrochloric acid plant.

[229][9. ***]

10. All effluents discharged including from the industries such as cotton textile, composite woolen mills, synthetic rubber, small pulp and paper, natural rubber, Petro-chemicals, tanneries, paint dyes, slaughter houses, food and fruit processing and dairy [230][industries] into surface waters shall conform to the BOD limits specified above, namely, 30mg/l.

(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/¹[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/¹[Nm³].

(g) In case of the urea plants commissioned after 1-1-1982, coke ovens and lead glass units, the PM emission shall be within 50 mg/¹[Nm³].

(h) In case of small boilers of capacity less than 2 tons/hr. and between 2 to 5 tons/hour, the PM emissions shall be within 1000 and 1200 mg/¹[Nm³].

(i) In case of integrated Iron & Steel Plants, PM emission upto 400 mg/¹[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 the cluster should be less than 600 [234][Nm²]. [235][***]

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 a 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 emissions 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.

[236][3. In case of copper, lead and zinc smelting, the off-gases may, as far as possible, be utilised for manufacturing sulphuric acid.]

[237][4. In case of cupolas (Foundries) having capacity (melting rate) less than 3 tonne/hour, the particulate matter emission 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 at least 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 emissions through the stack.]
