OFFICE OF THE YAMUNA POLLUTION MONITORING COMMITTEE APPOINTED BY HON’BLE NGT ROOM NO. 58, INDIA INTERNATIONAL CENTRE 40, MAX MUELLER MARG, LODHI ESTATE NEW DELHI – 110003 No. YPMC/2021/ 03 Dated: 15.01.2021 Subject: Issues regarding high level of ammonia in river Yamuna at Wazirabad. Dear Shri Vijai Vardhan, The Ammonia (Ammonical Nitrogen) content in the water reaching Delhi at Wazirabad had been found by experts from the Central Pollution Control Board (CPCB) and the National Environmental Engineering Research Institute (NEERI) to be largely attributable to heavy pollution emanating from specific drains in Haryana. The purpose of writing to you is to say that the root causes of the pollution resulting in high Ammonical content are well known but the action taken is not commensurate with the seriousness of the situation. As early as on 16.2.18 NGT had directed the Chief Secretaries of the State of Haryana and the NCT of Delhi to hold a meeting relating to water quality in Yamuna particularly high level Ammonical Nitrogen (NH3-N). If this was done the outcome is not known. The Yamuna Monitoring Committee (YMC) set up by the NGT has been repeatedly highlighting specific fault lines but we are not sure whether the recommendations of the CPCB and of NEERI given in 2019 have been brought to your notice. This email is to put things in perspective when the matter is reviewed at your level as the repeated assurances are not leading to any tangible improvement and allegedly creating huge problems in the operation of water treatment plants in Delhi. In 2018 when the Ammonical Nitrogen levels had risen, YMC had vide letter dated 3.12.18 asked a joint committee of CPCB and NEERI to visit the trouble spots and identify the points where engineering and allied modifications were called for. The report prepared on YMC’s request has been available on YMC’s website under KEY Communications but is attached again for ready reference. It remains relevant and is reproduced to put at rest any doubts about the quality of advice given which is independent and technically sound. CPCB/ NEERI Report’s Observations based on a Joint Survey on December 26-27, 2018: 1 1. Ditch drain is receiving wastewater of Yamuna nagar town and M/s RSL Distilleries Pvt Ltd. The Water quality of the ditch drain deteriorates further after D/s of M/s RSL Distilleries Pvt Ltd which clearly indicates that the said industrial unit discharges untreated effluent into the ditch drain. 2. M/s RSL Distilleries Pvt Ltd also have a discharge outlet along the boundary wall and there is a possibility that the unit discharges their untreated effluent intermittently to ditch drain. 3. Drain no. 2 was not receiving freshwater and only receiving wastewater from Panipat drain. 4. Water quality of river Yamuna deteriorates after d/s of Yamuna nagar and Panipat which shows that Ditch drain and drain no.2 are the substantial point sources of pollution for river Yamuna. 5. Earlier, Drain no. 8 was used for augmenting the flow of river Yamuna. During survey, the flow of drain no. 8 stopped and no water was allowed to merge river Yamuna. 6. Drain no. 6 and CETP Kondli were flowing in the embankment of drain no. 8 and there is a possibility of mixing of freshwater from Drain Number 8 with wastewater from drain no.6 and the CETP drain. 7. The analytical results also depict the impact of discharge of drain no. 6 and CETP- Kondli drain on drain no. 8 and the Yamuna river. 8. The embankment of CETP drain was temporarily repaired and there is need to increase the height of partition wall to avoid mixing. 9. During the survey, it was also observed that scattered habitations (Jagatpur Khadar Village, Milan Vihar, etc) existed between Palla to Wazirabad on the flood plain of river Yamuna. There is possibility of discharge of wastewater from these habitations to river Yamuna through temporary arrangements (tankers). 10. Concerned departments of Haryana told the Committee that accumulated sludge deposited in Wazirabad barrage is resulting in increased level of NH3-N. In this regard, it is to mention that sludge is accumulated in Wazirabad barrage due to wastewater discharge from drain no. 2 and drain no. 8. NH3-N formation from accumulated sludge will always be in stable environment condition and there is no role in episodic increase in NH3-N. Such increase in NH3-N level is 2 only observed either due to switching of fresh water flow from drain no.2, drain no.8, ( Hathnikund Barrage ) or disposal of wastewater(carrying sewage and septage) through tankers directly to river Yamuna. Recommendations of CPCB/ NEERI based on the Joint Survey : 1. Embankment/construction of dividing wall between drain no. 6 and 8 shall be expedited so that any possibility of mixing of wastewater with freshwater can be eliminated. After the construction of wall, drain no. 8 may be used for augmenting the freshwater flow of river Yamuna instead of drain no. 2. 2. Treated effluent of CETP-Kundli shall not be allowed to flow in the embankment of drain no.8. CETP’s treated effluent shall discharge into the recipient drain via closed conduit pipeline so that possibility of mixing with drain no. 8 shall be avoided. 3. Haryana SPCB shall issue direction u/s 33 A of Water (Prevention and Control of Pollution) Act 197 to M/s RSL Distilleries Pvt Ltd to stop effluent discharge to ditch drain. HSPCB shall also ensure that scattered dyeing units in Panipat shall not discharge their untreated effluent to Panipat drain. 4. Sewage treatment plant and Common effluent treatment plants installed at Yamuna nagar, Panipat and Sonepat city shall be made operational and optimally utilized. 5. All the waste water shall be conveyed to STPs and CETPs so that only treated wastewater is discharged into drains. 6. All the industries in Panipat and Sonepat city must operate their ETPs efficiently to meet the standard laid down under consent order and SPCBs shall ensure that no Industrial unit discharge its untreated effluent either into Yamuna river or into drains. 7. Delhi Jal Board shall ensure proposal disposal of sewage from scattered habitations (Jagatpur Khadar Village, Milan Vihar, etc) sited between Palla to Wazirabad. The NGT vide its order dated 26.7.18 had also directed Haryana State to set up a Haryana Monitoring Committee which has been inspecting the point source of pollution along the drains emanating from/passing though Panipat, Sonepat, Yamuna nagar, Karnal and Jagadhari as well as the drains on the Gurgaon/ Faridabad side has repeatedly highlighted the slow progress which has been reflected in YMC’s reports to NGT. Hon'ble NGT has passed several orders dated 29.1.19, 11.9.19, 18.2.20 and 6.7.20 and the progress made on complying with the directions have been highlighted and discussed by the YMC in 3 meetings held with both your predecessor Chief Secretaries of Haryana, namely, Shri D.S. Dhesi on 23.10.2018 in YMC’s office and Ms. Keshni Anand Arora on 10.1.2020 in Haryana Bhawan, Delhi and on 8.9.20, through video conferences. The minutes issued vide YMC's letters dated 5.11.18 and 10.9.20 & SEE (HQ), HSPCB's letter dated 21.1.2020 are available with the concerned officers and are not being repeated in order to stay brief. We write to urge you to introduce out -of- the -way strategies to fast track the work in hand, take deterrent and punitive action against the defaulting industries, see that the municipalities and PHED and other Civic agencies trap all sewage discharged by the habitations and register tankers carrying sewage/septage for discharge only at designated places and not into the river. YMC had asked the two Chief Secretaries and the Environment and Urban Development Principal Secretaries to ensure that the Septage Management Regulations are issued and the DM’s or Municipal officers made responsible for impounding and taking legal action against unauthorized tankers which was initiated by GNCT Delhi in November 2018. Although this was promised to be done several times, it has not become functional on the ground. The STPs and conveyance systems are taking very long to be completed according to the latest report of the Haryana Monitoring Committee experts whose findings are in the attachment. Despite all efforts if sewage and industrial discharge continues to defile the river causing incalculable harm to the environment and the quality of life of people, short-term alternatives will have to be started in parallel. i. NGT had already directed in its orders dated 11.9.19 and 18.2.20 that in situ bio/phyto--remediation in drains has to be undertaken to stop the untreated effluent going into the river using models of alternative technologies developed by CPCB. The progress on this has not been shared. ii. About the CPCB-NEERI findings it was advised that work on the construction of an embankment/ dividing wall between drain no. 6 and 8 must be put on fast track so that any possibility of mixing of wastewater with freshwater is eliminated. We understand that a closed conduit pipeline has been approved by the State but the share of individual Departments of Irrigation, ULBD, Industries and Finance have yet to be finalized. Funds can always be recouped from the departments later. Otherwise processes will take long and will delay the commencement of 4 construction. The work is sought to be completed by 31.5.21. It needs to be ensured that the there are no further slippages.
