: NORMS FOR SUGAR INDUSTRY :

1. The maximum quantity of water consumed in a sugar factory shall not exceed 2 cubic meter per tonne of cane crushed
2.

The factory shall ensure that all the effluents are collected and treated within the factory site before discharge, by providing scientifically designed treatment units of adequate capacity incorporating biological treatment systems for treatment of effluents to the standards stipulated by the State Pollution Control Board. Wherever methane recovery plants are adopted, the methane gas generated shall not be vented out to the atmosphere, but utilised in the factory itself to generate energy. 

3.

The treated effluent conforming to stipulated standards shall be invariably used for irrigation purpose and shall not be discharged to any stream, river or surface water body. Sugar factory shall possess adequate land to ensure complete utilization of treated effluents for agriculture. 

The application of treated effluent shall be controlled so as to avoid either flooding of land or ground water contamination. Before allowing the use of treated effluent for irrigation, the State Pollution Control Board shall ensure that the factory submits a report on geophysical characteristics and assimilation capacity of land. Adequate number of observation bores/test wells shall be provided by the factory in and around the irrigated area to monitor ground water quality.

4

Chimneys of required height and other air pollution control equipments like fly-ash arresters as prescribed I by the State Pollution Control Board shall be provided by the factory.

5 Bagasse shall be collected and stored properly by the factory to avoid fugitive emissions.
6

The factory shall. ensure that the noise levels are within the stipulated limits and shall conduct periodic monitoring of noise levels at designated locations at specified intervals.

7

Press mud generated can be sold without further treatment. However, in case it is not sold it shall be collected, composted within the factory under the supervision of factory's Scientists/Engineers before disposing it off. Leachate from the press mud shall be collected and treated and it shall not be allowed to soak down the earth nor create aesthetic nuisance nor contaminate the ground water. Composting pits shall be impervious. Necessary Certificate and the suitability of the composted press mud for agriculture shall be produced to the State Pollution Control Board.

8 Lime sludge shall be collected and disposed off by the factory scientifically as approved by the State Pollution Control Board.
9 Ash from the boilers shall be collected and disposed off by the factory scientifically as approved by the State Pollution Control Board.
10 The factory shall install water meters to measure the water consumed for different purposes as per the Water (Prevention and Control of Pollution) Cess Act, 1977, as amended, and pay water cess.
11

The factory shall submit an Environmental statement Report for the financial year ending the 31st March 
in the prescribed fonn to the State Pollution Control Board on or before the 30th day of September every year beginning 1993.

12 All tanks used for the storage and treatment of effluents shall be made impervious by providing adequate cement concrete/stone masonry/stone slab lining with leak proof joints in the bottom and sides. Observation bores with pipes shall be provided around such tanks and monitored for leakage.
13 The factory shall store the molasses generated in adequately sized steel tanks provided with roof cover.
14 The factory shall upgrade the pollution control systems as and when new technologies become available.
15 The factory shall ensure continuous and effective operation and maintenance of pollution control systems by employing qualified Environmental Engineers/Scientists.
16 The factory shall ensure continuous and uninterrupted power supply to see that the pollution control systems function uninterruptedly. Separate energy meter shall be provided for pollution control systems.
17 A fully equipped laboratory shall be established by the factory with appropriate equipments to monitor the performance of pollution control systems and to test the effluents, emission and soil for pollution related parameters.
18 Every new factory and those proposed to be expanded shall submit Environmental Impact Assessment Report and Environmental Management Plan to the State Pollution Control Board and Department of Ecology and Environment and obtain prior consent and environmental clearance respectively.
19 If the Occupier has not taken consents under the Water (Prevention and Control of Pollution) Act, 1974 and the Air (Prevention and Control of Pollution) Act, 1981, and clearance under the Environment (Protection) Act, 1986, he shall not be allowed to run the factory. Action shall be taken by writing to the concerned Departments to stop supplies such as electricity, water etc.
20 For convenience the Standards stipulated by the Karnataka State Pollution Control Board both under the water (Prevention and Control of Pollution) Act, 1974, and the Air (Prevention and Control of Pollution) Act, 1981, for the effluents and emissions discharged respectively are given below:

THE STANDARDS FOR EFFLUENTS AND EMISSIONS DISCHARGED FROM SUGAR INDUSTRY 

                                                                                               Concentration not to exceed Milligram per litre. 
1. Effluent:
Bio-chemical Oxygen Demand (5 days at 20.C)  100 for disposal on land.  
Suspended Solids 100 for disposal on land.
2. EMISSION:
Bagasse-fired Boilers. Emissions. Concentration in  mg/NM3
(a) Step grate. Particulate Matter  250
(b) Horse  Shoe/Pulsating Grate. Particulate Matter 500 (12% CO2 )
(c) Spreader Stroker. Particulate Matter  800 (12% CO2)

NOTE: In the case of horse shoe and spreader stroker boilers, if more than one boiler is attached to a single stack, the standard shall be fixed based on added capacity of all the boilers connected with the stack.
