[2]"1. PREAMBLE The Korattur People‟s Welfare & Awareness Trust had filed an application before the Hon‟ble National Green Tribunal (SZ) in application no.268 of 2016 with a prayer to restrain untreated effluent from industries directly letting into the Korattur Lake through the canals or in any manner.
The Hon‟ble NGT in its order dated 13.12.2016 directed the District Administration, Revenue Dept, PWD & TNPCB to plug the passage created for the purpose of sending the trade effluent to Korattur Lake. Further, the Hon‟ble NGT in its order dated 19.09.2017 has directed the Chennai Metropolitan Water Supply & Sewerage Board (CMWSSB) to file a report to control discharging the untreated sewage into Ambattur surplus cannel and also directed the TNPCB to furnish detailed report of industrial units viz the number of industries which are operating with Consent and without consent and the number of industries which are closed due to violations of the provisions of water (P&CP) Act 1974 and Air (P &CP) Act, 1981 in its order dated 06.12.2017.
Thereafter the matter has been adjourned from time to time. Currently, the applicant again brought to the notice of Hon‟ble NGT that the pathetic condition of the Lake is still continuing and the storm water drain has become the domestic discharge sewage drain and untreated sewage is being discharged into the Lake, thereby contaminating the water in the Lake.
2. ORDERS OF THE HON'BLE NATIONAL GREEN TRIBUNAL In the matter of application no.268 of 2016 (SZ), Korattur people‟s welfare & awareness trust, Chennai vs Government of India, rep. by its Secretary, MoEF & CC & Ors, the Hon‟ble National Green Tribunal vide its order dated 12.12.2019 has informed that though the matter is pending from 2016 onwards, no concrete steps have been taken by the authorities to solve the problem and the problem still continues and going from bad to worse and there is no proper action plan prepared by the authorities by coordinating with the responsible persons who will have to sit together to solve the issue as well to produce a final, effective solution to the problem.
There is responsibility on the local authorities to regulate the sewage system in the area before it is discharged into the river or water body. The State Government is also duty bound to take necessary steps to protect the environment so as to provide clean water, air and environment and ensure good health for the public, as part of right to life, as enshrined in Article 21 of the Constitution of India. The developments must go along with the protection of environment. If development alone is allowed to proceed with, ignoring the impact on environment, there will be none to enjoy the fruits of the same and as such sustainable development is a thing that has to be considered by the authorities while they are dealing with the development of environment. So there is a responsibility on the State to take remedial measures in coordination of all the departments which are responsible for keeping the health of the people in tact and making the environment clean. Mere projecting slogans, "clean environment" is not going to solve it. There must be comprehensive action plan to be prepared by the authorities to see that slogan has become a reality. So for that purpose, providing long time line in implementing the action plan, will only delay the project and affect the health of the people indirectly which cannot be allowed to continue.[3]
Considering these circumstances, the Hon‟ble National Green Tribunal in its order dated 12.12.2019 felt it appropriate to constitute a joint committee, consisting of (1) Principal Secretary for Urban Development Department, (2) Secretary, Public Works Department, (3) District Collector, Chennai, (4) Commissioner, Greater Chennai Corporation, (5) Senior Official of Metropolitan Water Supply & Sewage Board, (6) Senior Scientist/ Officer of Central Pollution Control Board, (7) Senior Officer/Senior Scientist Tamil Nadu Pollution Control Board and (8) IIT, Chennai to consider the question involved in the matter and prepare an action plan to find a permanent solution for the issue and execution of the same with shorter time line". If the Principal Secretary‟s presence is not be possible, he is free to nominate an officer, not below the rank of Additional Secretary, who is well versed with the matter.
The Hon‟ble National Green Tribunal in its order dated 27.02.2020 informed that the Principal Secretary, Municipal Administration and Water Supply Department have been substituted as joint committee member in the place of Principal Secretary for Urban Development Department.

6. DETAILED ANALYSIS OF ENVIRONMENTAL POLLUTION SOURCES AND ISSUES Inspection was carried out by the team comprising of TNPCB, Greater Chennai Corporation, CMWSSB, PWD and SIDCO in the Ambattur Lake, Ambattur Lake surplus canal, Korattur Lake entry and zero point to ascertain the status of disposal of domestic sewage from households located in the upstream of the Korattur Lake and industrial sewage from industries located in SIDCO industrial estate, TASS industrial estate & Patavatamman estate and Tiny shed into Ambattur Lake, Ambattur Lake surplus canal and also to ascertain the status of disposal of trade effluent generated from the industries located in Ambattur SIDCO industrial estate, TASS Industrial Estate and Patavatamman estate & Tiny shed into Ambattur Lake surplus canal and Korattur Lake.
Ambattur Lake is located at south west corner of the Greater Chennai Corporation area and the surplus water from Paruthipattu, Ayapakkam, Attheri and Arabatheri Lakes reaches the Ambattur Lake during monsoon season. The Ambattur Lake overflow is discharged via two surplus canals and finally these two are confluence as a single surplus canal at Teachers colony. Then the Ambattur surplus canal is passing through TASS Industrial Estate, Ambattur SIDCO Industrial Estate (North Phase) and finally reaches the Korattur Lake (Photographs of Discharge of sewage into Ambattur Lake, Ambattur Lake surplus canal and Korattur Lake is enclosed in Annexure V).
Further the Joint Inspection team identified the following issues i. Domestic sewage of 0.59 MLD generated from Jothi Nagar, Cholambedu Main road, Ganapathi Nagar, Annai Sathya Nagar, Periyar Nagar and New Anna Nagar which are part of Avadi City Municipal Corporation is directly let into Ambattur Lake since these areas do not have UGSS.
ii. Domestic sewage of 45 MLD generated in Zone 7 from Depot 79 to 93 of Greater Chennai Corporation is discharged into Korattur Lake and Cooum River, since some of the areas have not provided with UGSS [7] and in the areas with UGSS, the households are not yet connected with the system.
iii. Sewage generated from the industries located in TASS Industrial Estate is discharged into Ambattur Lake surplus canal which finally reaches the Korattur Lake, since TASS Industrial Estate is not provided with UGSS.
iv. Sewage generated from the industries located in Patavatamman Industrial Estate & Tiny Sheds is directly discharged into Ambattur Lake surplus canal and reaches Korattur Lake since there is no UGSS.
v. The SIDCO has installed two Common Sewage Treatment Plants (CSTP) (2 MLD capacity at North Phase and 3 MLD capacity plant at South Phase) in Ambattur Industrial Estate for the management of sewage generated from the units located in Ambattur industrial estate. The operation and maintenance of both CSTPs is being carried out by M/s.Chennai Auto Ancillary Industrial Infrastructure Up gradation Company (CAAIIUC). Many of the units located in Ambattur industrial estate (both in North phase & South phase) are disposing their waste oil/coolant oil into underground sewer line and reaches the CSTPs. Due to this the treated sewage could not achieve the standard prescribed for discharge into water bodies at Mega & Metropolitan Cities by the Hon‟ble NGT order dated 30.04.2019 in OA.No.1069/2018. Both the CSTPs have accumulated a total of 160 Tonnes of sludge in the premises.
vi. The unit of M/s.JBR Technologies Pvt. Ltd has provided the common effluent treatment plant (CETP) of 200 KLD capacity with ZLD for treating trade effluent from the member electroplating and allied units (Phosphating, Pickling etc.,). Currently the unit has provided the single stage RO system followed by Mechanical evaporator and the RO permeate is not reusable to industries because RO permeate is not meet out the quality of water to recycle in the electroplating units. The RO reject is further treated in the evaporator however the evaporator is not efficient. The unit has temporary stored the ETP sludge in open land within the premises for further handling. vii. Mixed Solid waste (Municipal Solid waste and Hazardous wastes) of 3 tonnes was dumped in 15th Street, Sector-1 (Tiny sector), Ambattur Industrial Estate, South Phase.
viii. Mixed Solid waste (Municipal Solid waste and Hazardous wastes) of 7 tonnes was dumped in 9 th Street, Sector-1 (Tiny sector), Ambattur Industrial Estate, North Phase (Photographs of mixed solid waste (municipal solid waste and hazardous waste) dumped locations in industrial estate is enclosed in Annexure VI). ix. The Municipal solid wastes generated from residences & industries located around the Ambattur Lake, Ambattur Lake surplus canal, Korattur Lake, TASS industrial estate, Patavatamman estate & Tiny sheds were being dumped haphazard in every corner of the streets and into the Ambattur Lake surplus canal.
x. The Municipal solid wastes generated from residences & industries located in and around the SIDCO Ambattur industrial estates were being dumped haphazard in the every corner of the streets located in the SIDCO Industrial area.
xi. Industrial hazardous waste such as grinding mud, oil soaked cotton waste, coolant oil generated from the industries are not handled properly and disposed inside the industrial estate in land, storm water lines.
xii. The Ambattur surplus canal is an earthen canal and in Ambattur surplus canal, hyacinths are fast growing and obstructing the free [8] flow of water due to discharge of sewage. There is no regulator arrangement in both the inlets and weir-2 near North Avenue of Korattur Lake to control inundation during the rainy season. xiii. The Extent of Korattur Lake is 590 Acres. Nearly 75% of land area is covered by Hyacinths, Prosophis, juliflora, weeds and floating material etc., The Korattur Lake is having 8500 m peripheral length, out of which 6800 m length is having bund and the remaining portion of 1700 m is foreshore area. In the foreshore area encroachments are found in some places. Municipal solid waste and sewages from these encroachments are directly let into the Korattur Lake.
7.

From the report of analysis, it is found that the water is meeting the standards prescribed for drinking water source with conventional treatment followed by disinfection (Class C) except for the tolerance limit of BOD.
e) Korattur Lake water samples for heavy metal and other parameter analysis The water samples were collected in Korattur Lake on 11.02.2020 and the characteristics of heavy metal and other parameters such as pH, DO, COD, BOD, TDS & Total Coliform presents in the water samples were compared with the tolerance limit for Inland surface water subject to pollution IS:2296-1982 are illustrated in Table 5 of Annexure XI. From the results, it is found that the heavy metals are with the standards prescribed by the Inland surface water (Class C-Drinking water source with conventional treatment followed by disinfection).
From the report of analysis of water samples collected at various locations in Korattur Lake, it is found that the DO level is varied in range of 4.09-4.36 mg/l, the value of Faecal coliform is varied in the range of 90-130 MPN/100 ml and the BOD value is varied in the range of 13-20 mg/l. From the report of analysis, it is found that the water is meeting the standards prescribed for drinking water source with conventional treatment followed by disinfection (Class C) except for the tolerance limit of BOD.
f) Water and sludge samples from Common Sewage Treatment Plant, North Phase The sewage samples were collected in North phase of Common STP on 11.02.2020 and 02.03.2020. The characteristics of sewage samples are compared with inland surface water Parameters for discharge standards of trade effluent for heavy metals and with discharge of treated sewage into water bodies for other parameters at Mega & Metropolitan Cities by the Hon‟ble NGT order dated 30.04.2019 in OA.No.1069/2018 are illustrated in Table 6 of Annexure XII.
From the report of analysis of raw and treated sewage samples collected in north phase CSTP, it is found that the parameters are within the standards prescribed for inland surface water Parameters for discharge standards of trade effluent for heavy metals. Also it is found that the other parameters of COD, BOD, TSS and Total Nitrogen values are exceeded in treated sewage compared with standards prescribed by discharge of treated sewage into water bodies for other parameters at Mega & Metropolitan Cities.
The dumped sludge sample was collected in North of Common STP on 11.02.2020 for heavy metal analysis. From the results it was found that the heavy metals are present in the sludge samples which indicate that the electroplating industrial effluents were discharged with raw sewage. The result of sludge analysis is illustrated in Table 6 of Annexure XII.
[13]g) Water and sludge samples from Common Sewage Treatment Plant, South Phase The sewage samples were collected in south phase of Common STP on 11.02.2020 and 02.03.2020. The characteristics of sewage samples are compared with inland surface water Parameters for discharge standards of trade effluent for heavy metals and with discharge of treated sewage into water bodies for other parameters at Mega & Metropolitan Cities by the Hon‟ble NGT order dated 30.04.2019 in OA.No.1069/2018 are illustrated in Table 6 of Annexure XII.
From the report of analysis of raw and treated sewage samples collected in CSTP, it is found that the parameters are within the standards prescribed for inland surface water Parameters for discharge standards of trade effluent for heavy metals except Zinc in raw sewage (4.309 mg/l) which indicates that the zinc plating effluent is mixed with raw sewage. Also it is found that the other parameters of COD, BOD, Total Nitrogen, Total Phosphors and Faecal Coliform values are exceeded in treated sewage compared with standards prescribed by discharge of treated sewage into water bodies for other parameters at Mega & Metropolitan Cities.
The dumped sludge sample was collected in south phase of Common STP on 11.02.2020 for heavy metal analysis. From the results it was found that the heavy metals are present in the sludge samples which indicate that the electroplating industrial effluents were discharged with raw sewage. Hence the CAAIIUC has included the disposal of accumulated sludge of 160 T at both CSTPs to TSDF, Gummidipoondi in their action plan. The results of sludge analysis are illustrated in Table 6 of Annexure XII.
h) Common Effluent Treatment Plant samples for heavy metals The trade effluent samples were collected in Common Effluent Treatment Plant on 11.02.2020 and the characteristics of effluent samples are illustrated in Table 7 of Annexure XIII. From the results, it was found that the heavy metals are within the standards prescribed by the Inland surface water Parameters for discharge standards of trade effluent in both RO permeate and RO reject.

h) Tamil Nadu Pollution Control Board The Hon‟ble NGT in its order dated 12.12.2019 has directed the Tamilnadu Pollution control Board to inspect the industries, including the „white ‟ category industries in that area and find out whether any violation is committed by them. If there is any violation, they will have to take appropriate action to abate the same and if any upgradation is required on account of pollution load in that area, that also will have to be considered by the state Pollution Control Board and appropriate change of category will have be restored and it will have to be brought under the consent mechanism, if it required. Also directed the Tamilnadu Pollution control Board to consider the BOD, COD and faecal coliform present in the water in that area in order to ascertain the quality of the water and find out whether they are complying the norms whether the existing system is adequate to meet the situation. If not, proper alternate mechanism to meet the condition or standardisation of the STP to meet the situation has to be done.
They are also directed to consider the criteria to ascertain the presence of dangerous metals, if any, which is likely to affect the human health. The DEE, TNPCB, Ambattur has submitted the short term and long term action plan to comply above said directions (copy of the action plan is enclosed as Annexure XXI).

10. ENVIRONMENTAL COMPENSATION
The Hon‟ble NGT order dated: 12.12.2019 has directed the committee shall also go into the question regarding the damage caused to the environment on account of the unbridled discharge of sewage and trade effluents and the remedial measures to mitigate the damage caused to the environment and restore it to its original position and if necessary they can also identify the persons who are responsible for the same and assess environment compensation and recover the same from those persons who are responsible for the same in proportion to the contribution made by them applying "polluters pay" principle and submit a report in this regard as well.
Environmental Compensation for Violated industries The Hon‟ble NGT in its order dated 13.12.2016 directed the District Administration, Revenue Dept, PWD & TNPCB to plug the passage created for the purpose of sending the trade effluent to Korattur Lake. Based on this order, the TNPCB has taken action against the violating industries from January 2017 for the following violations.
1. Discharge of untreated/partially treated trade effluent into the storm water drain and it reaches the Ambattur Lake surplus cannel which leads soil and water pollution
2. Non compliance of the conditions stipulated in the CTO/RCO and violations of the consent order conditions issued by the Board.
3. Unit was under operation without consent to operate of the Board and violating the provisions of the Water and Air Acts
4. Disposal of hazardous waste such as coolant oil, grinding mud and oil chocked cotton waste in Industrial estate The TNPCB has levied the interim environmental compensation to 153 units located in Ambattur SIDCO industrial estate (both north and south phase) for above said violations as furnished by the DEE, TNPCB, Ambattur. The environmental compensation has been calculated for the violated units under "polluters pay principal" by using the following formula EC = PI x N x R x S x LF Where, EC - Environmental compensation in Rupees PI - Pollution index of industrial sector.
The average pollution index of 80, 50 and 30 has been taken for calculating the environmental compensation for Red, Orange and Green categories of industries.
[36]N - Number of days for which violation took place is the period between the days of violation observed/ due date of compliance of directions and the day of compliance verified by CPCB/ SPCB/PCC.
The number of days were calculated between the day of violation identified (date of inspection) and day of violation stopped (date of EB supply disconnection) R - A factor in rupees for EC.
The minimum and maximum value of factor is 100 and 500. The minimum value of factor i.e.100 is considered in the environmental compensation calculation because all the defaulting units are micro and small scale units. The suggested value of factor R is considered as 250 for medium and large scale industries.
S - Factor for scale of operation.
S could be based on small/medium/large industry categorization, which may be 0.5 for micro or small, 1.0 for medium and 1.5 for large units.
LF - Location factor based on population of the city/town and location of the industrial unit. The Ambattur is added with Greater Chennai Corporation (GCC) as Zone -7 and while calculating EC, only the Zone-7 population as per guidelines (less than one million) was considered instead of entire GCC and hence it comes under Class-1 City/Town based on population. The value of LF is 1 for city/town having population less than one million.
Model Calculation for Red Category (Micro and Small units):
PI - The average Pollution Index industrial sector for Red Category
- 80 N - The number of days were calculated between the day of violation identified (date of inspection) and day of violation stopped (date of EB supply disconnection) R - The minimum value of factor i.e.100 was considered in the environmental compensation calculation because all the defaulting units are micro and small scale units. S - Factor for scale of operation small scale category - 0.5 LF - The value of LF is 1 for city/town having population less than one million.
EC = PI x N x R x S x LF
= 80 x 1 x 100 x 0.5 x 1
= Rs.4000 per day (Rupees Four Thousand per day)
Model Calculation for Orange Category (Micro and Small units) PI - The average Pollution Index industrial sector for Orange Category - 50 N - The number of days were calculated between the day of violation identified (date of inspection) and day of violation stopped (date of EB supply disconnection) [37] R - The minimum value of factor i.e.100 was considered in the environmental compensation calculation because all the defaulting units are micro and small scale units. S - Factor for scale of operation small scale category - 0.5 LF - The value of LF is 1 for city/town having population less than one million.
EC = PI x N x R x S x LF
= 50 x 1 x 100 x 0.5 x 1
= Rs.2500 per day (Rupees Two Thousands Five Hundred per
day)
Model Calculation for Green Category (Micro and Small units) PI - The average Pollution Index industrial sector for Green Category - 30 N - The number of days were calculated between the day of violation identified (date of inspection) and day of violation stopped (date of EB supply disconnection) R - The minimum value of factor i.e.100 was considered in the environmental compensation calculation because all the defaulting units are micro and small scale units. S - Factor for scale of operation small scale category - 0.5 LF - The value of LF is 1 for city/town having population less than one million.
EC = PI x N x R x S x LF
= 30 x 1 x 100 x 0.5 x 1
= Rs.1500 per day (Rupees Thousands Five Hundred
per day)
Model Calculation for Orange Large Category PI - The average Pollution Index industrial sector for Orange Large Category - 50 N - The number of days were calculated between the day of violation identified (date of inspection) and day of violation stopped (date of EB supply disconnection) R - A Factor in rupees for EC which may be a minimum of 100 and maximum of 500; it is suggested to consider R as 250. S - Factor for scale of operation large small scale category - 1.5 LF - The value of LF is 1 for city/town having population less than one million.
EC = PI x N x R x S x LF
= 50 x 1 x 250 x 1.5 x 1
= Rs.18750 per day (Rupees Eighteen Thousand Seven
Fifty per day)
The total amount of Rs.1,09,69,500/- has been levied as interim environmental compensation for the defaulting units for above said violations and the list of defaulting industries along with environmental compensation is illustrated in Annexure - XXII.
M/s.TI Cycles of India, Ambattur The unit of M/s.TI Cycles of India was inspected on 08.11.2019 and 13.11.2019 by the team and recommended for direction for closure and disconnection of power supply under Section 33A of Water (P&CP) Act, 1974 as amended and under Section 31A of Air (P&CP) Act, 1981 as amended for the following violations.[38]
1. The unit has stored the untreated trade effluent (process effluent) in sewage treatment plant sludge drying bed and illegally dumped the HW such as ETP sludge/STP sludge in STP area and the sludge is washed away along with rain water and discharged into Ambattur surplus canal and then to reach Korattur Lake.
2. The unit has disposed the partially treated sewage & trade effluent/untreated sewage & trade effluent into the land located at backside of industry i.e. adjacent to Ambattur Lake and also the discharged effluent into land reaches the Ambattur Lake surplus cannel which pollutes soil and water.
3. The unit has not segregated the hazardous waste from trade effluent by not operating the ETP & RO plants and the sludge along with trade effluent is disposed on land with acidic in nature and the trees are dead.
4. The unit has caused the environmental damages such as contamination of soil, ground water, surface water and caused the damage of tree planted in the land.
Hence, the TNPCB has levied the environmental compensation of Rs.10.35 lakhs for damage to the environment and penalty of Rs.29 Lakhs violation towards of provisions of Hazardous and Other Wastes (Management and Transboundary Movement) Rules, 2016 for the unit of M/s.TI Cycles of India, Ambattur Village, Ambattur Taluk, Chennai District vide Proceeding No.T4/TNPCB/F.0787AMB/RL/W&A/2019 dated 6.12.2019 by considering the environmental compensation formula and penalty calculation provided by CPCB guideline and the number of day‟s violation was taken from 11.11.2019 to 30.11.2019. Further, the unit has taken corrective measures for the directions issued by the TNPCB and also the action plan furnished by the unit is enclosed in Annexure-XXIII.
11. SUMMARY AND CONCLUSION As per the Hon‟ble NGT direction dated 12.12.2019 and 27.02.2020, the TNPCB has communicated a letter to the line departments to nominate the members.

[43]4. It is mentioned in Para 11 of the committee's report the work that has been entrusted to each stakeholders for the purpose of meeting the situation in an effective manner. It is seen from the report that considerable work has been done, on the basis of the directions given by this Tribunal, by the concerned stakeholders for the purpose of protecting the water bodies against the encroachment and pollution. But still some more work has to be completed and unless such work is completed in a war-footing, the effort so far taken by them will be nullified and they will have to continue to proceed with the projects undertaken by them to implement the schemes launched by them for this purpose effectively and quickly as well.
5. It is seen from the report that certain work that has been started has come to a standstill due to the impact of Covid-19 but situation has changed now and people have become effective in their work. So, they can restart their work with the same zeal and see that the work is completed in a shorter time line and not take time till 2025. The environment cannot be allowed to be polluted for such a long time as it will have a greater impact on health of the people. Priority must be given in carrying out the work which is required for the purpose of protecting environment [44] apart from fulfilling their other statutory obligations of providing other facilities to the people.

However, when the nature [45] of progress that has happened after filing of the report was asked for, the counsel representing the committee as well as the individual regulating authorities submitted that if some time is granted, they will come with a progress report. We are aware that it is a long term process as things were not happening in a happy manner for a long time and in order to rectify those things in a right way, they may take some more time. But at the same time, no lethargic attitude should be shown by the stakeholders in implementing the scheme which they have launched and they must show all earnest attempt to complete the work so as to make the Korattur Lake free from pollution and encroachment and create an eco-friendly environment in that area so as to make the life of the people happy and healthy.
10. The learned counsel appearing for the applicant submitted that though earlier the unauthorized sewage connections were blocked and also the electricity connections were disconnected in respect of certain industries but due to political pressure, the same have been opened and the unauthorized industries are still working with the same method of discharge as was been done earlier causing pollution to the river.
[46]11. It is also seen from the subsequent newspaper report published in The Time of India dated 10.12.2019 that the sewage is being let into the Korattur Lake.
12. The learned counsel appearing for the applicant also showed some photographs taken by the residents of the locality which showed the pathetic contaminated condition of the water on account of discharge of untreated effluents into those drains by the industrial units.
13.
