Press Release
Date: 4th June 2010
Effluent Treatment Facilities across Golden Corridor does not conform to GPCB Norms.
BUT WHO CARES?
Stop effluent discharge at Tadgam Sarigam Pipeline, from FETP, Ankleshwar, ECP, Vadodara, CETPs of Ahmedabad as the effluent is not able to meet the norms prescribed by Gujarat Pollution Control Board.
– Paryavaran Suraksha Samiti
The problem of industrial pollution first came to light in the nineties, when the issue gained momentum among urban entities about a decade after the Bhopal disaster. Due to pressure from various communities and environmental organizations, courts began intervening in cases to ultimately build the waste “treatment facilities” that exist today. These actions, which were championed by the media, created an entire culture of complacence that “something” great had been done about the pollution. There was a collective urban sentiment that citizens were protected from industries because of the mitigation infrastructure. Despite the “Polluter Pays” principle, even in the nineties the then developing common effluent treatment plants (CETPs) were highly supported by public money; 25% of the cost was state subsidy, 25% central subsidy, 30% loans from financial institute, and 20% directly paid by the industry. In essence half of the proposed solution to the pollution generated for private profit was funded by the general public. Moreover this happened at the same time that the state was withdrawing from its social responsibilities, such as education, health care and transportation. It seems paradoxical that the mounting laissez faire sentiment allowed the state to intervene on behalf of industries – which come to exist by virtue of concentrated resources and power – but not for the welfare of the common masses. Even after such huge investment many of the CETPs including Vapi, FETP – Ankleshwar, Panoli, Nandesari, Vatva, Odhav, Narol etc. are not able to meet the prescribed GPCB norms.
Sarigam: Legal Notice dated 4th December 2009 issued to Sarigam Waste & Effluent Management Co. Ltd., Sarigam, District – Valsad by Gujarat Pollution Control Board under section 33-A of The Water (Prevention and Control of Pollution) Act, 1974 clearly states that “[…] the consent granted to you vide order No. 1623 dated 12-2-2004 has lapsed on dated 31-3-2004 hence, at present you are operating industrial effluent disposal system without CC & A of the Gujarat Pollution control Board under the provision of Water Act.” It further states “[…] during the inspection of your plant on 18-11-2009 … The analysis reports indicates that the concentration like SS, BOD, COD, Chloride, Ammonical Nitrogen, Phenolic Compound, Zinc, & Sulphides, are most of the time higher than the permissible limit specified by the Board.” This clearly indicates that the treatment facility dumps the effluent at village Tadgam without proper permission and effluent does not meet GPCB’s norms.
Vapi CETP: The CPCB report dated 29-3-2010 indicates that effluent being discharged into Damanganga river shows COD: 869 i.e. 347.60% more (GPCB norms 250 mg/l), TDS: 9088 i.e. 432.76% more (GPCB norms 2100 mg/l), and NH3-N: 98 i.e. 196% more (GPCB norms 50 mg/l).
Ankleshwar FETP: The report dated 10-3-2010 of CPCB indicates that effluent discharged into the Gulf of Cambay shows COD: 1241 i.e. 248.20% more (GPCB norms 500 mg/l), and NH3-N: 664 i.e. 1328% more (GPCB norms 50 mg/l).
Effluent Channel Project (ECP), Vadodara: The report indicates that effluent discharged into estuary of Mahisagar river shows pH: 4.6 (GPCB norms 6.5 – 8.5), TSS: 361 (GPCB norms 100 mg/l), TDS: 14458 (GPCB norms 5000 mg/l), COD: 1826 (GPCB norms 250 mg/l), BOD: 334 (GPCB norms 100 mg/l), NH3-N: 387 (GPCB norms 50 mg/l), Cyanide: 2.857 (GPCB norms 0.2 mg/l), and Phenols: 15.37 (GPCB norms 1.0 mg/l).
Ahmedabad, CETP: (1) CETP, Vatva: The report dated 27-1-2010 of CPCB indicates that effluent discharged into Sabarmati river shows COD: 2189 i.e. 879.20% more (GPCB norms 250 mg/l), TDS: 16141 i.e. 768.60% more (GPCB norms 2100 mg/l), and NH3-N: 190 i.e. 380% more (GPCB norms 50 mg/l). (2) CETP M/s GECSL, Vatva: The report dated 29-1-2010 of CPCB indicates that effluent discharged into Sabarmati river shows COD: 1100 i.e. 440% more (GPCB norms 250 mg/l), and TDS: 2506 i.e. 119.33% more (GPCB norms 2100 mg/l). (3) CETP M/s GVMSAVL, Odhav: The report dated 28-1-2010 of CPCB indicates that effluent discharged into Sabarmati river shows COD: 7315 i.e. 2926% more (GPCB norms 250 mg/l), TDS: 6928 i.e. 329.90% more (GPCB norms 2100 mg/l), and NH3-N: 1260 i.e. 2520% more (GPCB norms 50 mg/l). (4) CETP M/s NEPL, Naroda: The report dated 28-1-2010 of CPCB indicates that effluent discharged into Sabarmati river shows COD: 2471 i.e. 988.40% more (GPCB norms 250 mg/l), TDS: 11971 i.e. 570.00% more (GPCB norms 2100 mg/l), and NH3-N: 190 i.e. 380% more (GPCB norms 50 mg/l).
An expensive distraction
In Gujarat, one of the newest such projects is the Final Effluent Treatment Plant (FETP). Touted by the Chief Minister, Mr. Narendra Modi, the Gujarat Pollution Control Board (GPCB), and various Industries Associations as a state-of-the-art solution the structure is designed to divert industrial pollution from Amlakhadi and the Narmada River. First, all of the effluent from the CETPs at Industrial Estates at Ankleshwar, Panoli, and Jhagadia are transported to the FETP plant located in Piraman village, Ankleshwar. Next, the consolidated “treated” effluent is theoretically re-treated to meet GPCB norms. The final “treated” effluent is then transported via a 53 km pipeline to Hansot where it is ultimately discharged into the sea. Operated by Bharuch Eco Aqua Infrastructure Ltd, the pipeline was inaugurated with a capacity of 40 million liters per day (MLD), which has since been increase to 60 MLD to meet the need of the estates.
The FETP was built by the sweat of tax payers. Out of a total project cost of Rs 131.43 crores, the industries paid only Rs 21.75 crores (about 17%); the rest of the tab (Rs 109 crores) was picked up the Central Government, Gujarat Government, and Gujarat Industrial Development Corporation (GIDC) – all of which ultimately draw from public money. It is a familiar story: the profits are distributed privately, but the institutional costs and environmental burden are borne by general public.
The FETP was conceived to relieve local communities of the waste waters from Ankleshwar, Panoli, and Jhagadia Industrial Estates for which it is responsible. It is an open secret that the people living along Amla Khadi, however, are still suffering from industrial effluents. Any passerby can still see the colored water, and the tributary still has fluctuating acidity (some time a pH of 2 to 6). These observations suggest that illegal discharge into the Amlakhadi, the classic industrial dustbin of Ankleshwar, has not ended. But it gets more disconcerting. We investigated the performance of the FETP itself, by exercising our Right to Information regarding this essentially publicly funded and endorsed endeavor. We learned that the Central Pollution Control Board (CPCB) has been concerned with the prescribed norms of the FETP from the onset. As early as 2006 and repeatedly in 2007, the CPCB has noted that the FETP is not able to meet the prescribed norms. And because of that no expansions and no new industries can legally be sited in the area from 7-7-2007. At the behest of CPCB, GPCB was forced to issue a letter to the Industries Association of Ankleshwar, Panoli, and Jhagadia that no NOC could be given for new industrial and expansion in this area. Any increased traffic in the FETP would exacerbate the existing non-compliance of environmental protocols. We were shocked to discover through state documentation that between 2006 and March 2010, none of the routine monthly checking of standard pollutants in released effluent was within GPCB norms. This is not solely a failure of the FETP – the waste waters sent to the FETP (“inlet” effluent) were outside the norms in the first place – so it is also a failure of the CETP process of Ankleshwar, Panoli and Jhagadia. There is hardly any dent made by the FETP – not just that outlet norms not are achieved but even inlet norms are not met. In effect, the FETP seems to be a physical structure for consolidating and transporting waste, not for treating it. One of the main shocking information is that this plant was not able to meet the norms since 2006 even then the Chief Minister of Gujarat inaugurated a pipeline of the same plant on 25th January 2007 and Centre and State Government invested more than Rs. 100 crores in the company. The explanation for such an act was asked by us from the Chief Minister Office but there was no reply.
Environmental injustice
Adding insult to tax-payers’ injury, pollution mitigation infrastructure is as neglected as the pollutants themselves, causing a mutually reinforcing stalemate in the problem of pollution control. Yet, instead of becoming stricter with environmental clearances given to new and expanding potentially polluting industries, the Centre is taking steps to make the process more lenient so that India can march forward to “develop” without obstruction. Instead of focusing on the infrastructure that we do have and making it functional, the state seems obsessed with building new projects that tend to fail just like their predecessors.
The above open secret – realities invites strong action from GPCB under Environment Laws against all these facilities and we strongly feel that no effluent discharge should be allowed from any of these facilities with immediate effect.
We demand: Stop effluent discharge at Tadgam Sarigam Pipeline, from FETP, Ankleshwar, ECP, Vadodara, CETPs of Ahmedabad as the effluent is not able to meet the norms prescribed by Gujarat Pollution Control Board.
