Standards for Equipment Leaks

(1) Approach: Approach for controlling fugitive emissions from equipment leaks shall have proper selection, installation and maintenance of non-leaking or leak-tight equipment. Following initial testing after commissioning, the monitoring for leak detection is to be carried out as a permanent on-going Leak Detection and Repair (LDAR) programme. Finally detected leaks are to be repaired within allowable time frame.

(2) Components to be Covered: Components that shall be covered under LDAR programme include (i) Block valves; (ii) Control valves; (iii) Pump seals; (iv) Compressor seals; (v) Pressure relief valves; (vi) Flanges-Heat Exchangers; (vii) Flanges-Piping; (viii) Connectors-Piping; (ix) Open ended lines; and (x) Sampling connections. Equipment and line sizes more than 1.875 cm or ¾ inch are to be covered.

(3) Applicability: LDAR programme would he applicable to components (given at 2 above) for following products/compounds: (i) hydrocarbon gases; (ii) Light liquid with vapour pressure @ 20°C > 1.0 kPa; and (iii) Heavy liquid with vapour pressure @ 20°C between 0.3 to 1.0 kPa.

(4) While LDAR will not he applicable for heavy liquids with vapour pressure <0.3 kPa, it will be desirable to check for liquid dripping as indication of leak.

(5) Definition of leek: A leak is defined as the detection of VOC concentration more than the values (in ppm) specified below at the emission source using a hydrocarbon analyzer according to measurement protocol (US EPA-453/R-95-017, 1995). Protocol for equipment leak emission estimates may be referred to :

Component General Hydrocarbon (ppm) Benzene (ppm)
Till 31st Dec., 2008 w.e.f. January 01, 2009 Till 31st Dec., 2008 w.e.f. January 01, 2009
Pump/Compressor 10000 5000 3000 2000
Valves/Flanges 10000 3000 2000 1000
sOther components 10000 3000 2000 1000

(6) In addition, any component observed to be leaking by sight, sound or smell, regardless of concentration (liquid dripping, visible vapor leak) or presence of bubbles using soap solution should be considered as leak.

(7) Monitoring Requirements and Repair Schedule: Following frequency of monitoring of leaks and schedule for repair of leaks shall be followed:
Component Frequency of monitoring Repair schedule
Quarterly (semiannual after two consecutive periods with < 2% leaks and annual after 5 periods with < 2% leaks) Repair will be started within 5 working days and shall be completed within 15 working days after detection of leak for general hydrocarbons. In case of benzene, the leak shall be attended immediately for repair.
Pump seals Quarterly
Compressor seals Quarterly
Pressure relief devices Quarterly
Pressure relief devices (after venting) Within 24 hours
Heat Exchangers Quarterly
Process drains Annually
Components that are difficult to monitor Annually
Pump seals with visible liquid dripping Immediately Immediately
Any component with visible leaks Immediately Immediately
Any component after repair/ replacement Within five days

(8) The percentage leaking components should not be more than 2% for any group of components, monitored excluding pumps/compressors. In case of pumps/compressors, it should be less than 10% of the total number of pumps/compressors or three pumps and compressors, whichever is greater.

(9) Emission Inventory: Refinery shall prepare an inventory of equipment components in the plant. After the instrumental measurement of leaks, emission from the components will be calculated using stratified emission factors (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.

(12) Pressure relief and blow down systems should discharge to a vapour collection and recovery system or to flare.

(13) Open-ended lines should be closed by a blind flange or plugged.

(14) Totally closed-loop should be used in all routine samples.

(15) Low emission packing should be used for valves.

  1. 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

3. Colour and Odour No noticeable colour or offensive odour. Specially caused by chemical compound like creosols, phenols, naphtha pyridine benzene, toluene, etc., causing visible colouration of salt crystal and tainting fish flesh.
4. Floating Matters Nothing obnoxious or detrimental for use purpose. Surfactants should not exceed an upper limit of 1.0 mg/1 and the concentration not to cause any visible foam.
5. Suspended Solids None from sewage or industrial waste origin Settleable inert matters not in such concentration that would impair any usages specially assigned to this class.
6. Oil and Grease (including Petroleum Products) 0.1 mg/1 Concentration should not exceed 0.1 mg/1 as because it has effect on fish eggs and larvae.
[7.] Heavy Metals: Values depend on :
Mercury (as Hg) 0.001 mg/1 (i) Concentration in salt, fish and shell fish.
Cadmium (as Cd) 0.001 mg/l (ii) Average per capita consumption per day.
Lead (as Pb) 0.01 mg/1 (iii) Minimum ingestion rate that induces symptoms of resulting diseases.

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.

  2. 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 alongwith the rationale in Table 1.

TABLE 1
PRIMARY WATER QUALITY CRITERIA FOR BATHING WATER

(Water used for organised outdoor bathing)

CRITERIA RATIONALE
1. Fecal Coliform MPN/100 ml: 500 (desirable) 2500 (Maximum permissible) To ensure low sewage contamination. Fecal Coliform and Fecal Streptococci are considered as they reflect the bacterial pathogenicity.
2. Fecal Streptococci MPN/100ml: 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/1 or more The minimum dissolved oxygen concentration of 5 mg/1 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, 27oC: 3 mg/1 or less The Biochemical Oxygen Demand of 3 mg/1 or less of the water ensures reasonable freedom from oxygen demanding pollutants and prevents 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 standards 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 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 omissions 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 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 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 chlorie acid plant.

[***]

  1. All effluents discharged including from the industries such as cotton textile, composite woollen mills, synthetic rubber, small pulp and paper, natural rubber, petro-chemicals, tanneries, paint, dyes, slaughter houses, food & fruit processing and dairy [industries] into surface waters shall conform to the BOD limits specified above, namely, 30 mg/ 1. For discharge of an effluent having a BOD more than 30 mg/1, the standards shall conform to those given above for other receiving bodies, namely, sewers, coastal waters and land for irrigation.

[***]

  1. 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.
  2. In case of pesticides :

(a) The limits should be complied with at the end of 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 notabilities 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.

[14. The chemical oxygen demand (COD) concentration in a treated effluent, if observed to be persistently greater than 250 mg/1 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 Wastes (Management and Handling) Rules, 1989 the State Boards in such cases shall direct the industries to install tertiary treatment stipulating time limit.

  1. Standards specified in Part A of Schedule VI for discharge of effluents into the public sewer shall be applicable only if such sewer lead to a secondary treatment including biological treatment system, otherwise these discharge into sewers shall be treated as discharge into inland surface waters.]

ANNEXURE II
(For the purpose of Part D)

  1. The State 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, the 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 up to 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%CD2) 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 1-1-1982, 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 1600 and 1200 mg/[Nm3].

(i) In case of integrated Iron and Steel Plants, PM emission up to 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 metres from a controlled, isolated as well as from a unit located in the cluster should be less than 600 micrograms/[Nm3].

[***]

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, form 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.

  1. The total fluoride emissions in respect of Glass and Phosphatic Fertilizers shall not exceed 5 mg/NM3 and 25 mg/NM3 respectively.
  2. [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 emission shall be within 450 mg/Nm3. In these cases it is essential that stack is constructed over the cupola 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.]
