During inspection, villagers approached the committee and informed that effluent is discharged outside Kesanapalli GGS into empty land. Committee visited the area and observed that outside the boundary wall of the unit, water stagnation (lagoon/ pond) was present at two locations and villagers informed that it is effluent discharged from the installation. At one location just beside the boundary wall of the unit large quantity of slightly reddish colored water was present. The boundary walls of the unit are weak, cracks & small openings are developed on the wall towards old ETP. Committee collected inlet & outlet samples of old & new ETP, samples from two water stagnation points and beach water (near to disposal line) and analysis results for core parameters are as follows:

Though the installations at Kakinada asset and Rajahmundry asset are currently operating under loss but however the overall profit made by M/s ONGC nationwide is considered for CSR fund utilization. Reported that 5% of theoverall profit made by M/s ONGC is utilized for CSR activities and the total profit is dividedamong all installations. Based on the CSR proposals received by various modes such as through District Collector, NGO's, Public representatives etc are compiled and approval is obtained through their key executive/ corporate head. Kakinada asset & Rajahmundry asset prepare a CSRplan based on the proposals received and on the allocated amount to each installation. Both Rajahmundry and Kakinada asset are having a CSR co-ordinator for implementation of CSR activities.

The CSR proposals received from various domain are first examined by the CSR co-ordinator by way of field visit or verifying the DPR etc and after examining the proposals it is put up to an internal screening committee and then to virtual corporate committee. These committee further examine and recommend the activities after which approval is obtained. Based on the proposal received CSR activity is implemented and then it is monitored by either CSR co-ordinator or project monitoring team. Post implementation & monitoring, documents are obtained such as utilization certificates etc and activity is completed.

For ground trothing purposes, committee verified the CSR records for last five years (2017 onwards) and also visited areas where activities are implemented such as installation of water tanks, providing cycle stand for school children etc. Committee interacted school Principle, Tehsildar and it was reported that CSR activities are taken up the units.

Four village heads met the committee and requested the committee to direct M/s ONGC to release more amount to the villages where the wells are located rather than spending the amount in diverse manner and in other villages. Committee clarified the Village heads that committee is verifying as to whether CSR funds are properly utilised or not. M/s ONGC Rajahmundry asset has spent around Rs. 21.04 crores on CSR activities during 2018-19, Rs. 23.05 crores during Page 33 of 39 34 Inspection Report in the matter of OA 175/2020 (SZ) 2019-20 and Rs. 8.08 crores during 2020-21 respectively. Reported that during 2020-21, M/s ONGC has contributed to PM cares fund and hence hence there is a decline in amount spent on CSR activity in the region.

The committee interacted with the applicant and objections were raised on installation of two Water ATM's in Antharvedi Devasthanam and nearby village. Committee visited both the water ATM's and discussed with the M/s ONGC team. Based on the proposals received, M/s ONGC has proposed to two install water ATM's. Water ATM's are water treatment machines (basically RO system) which either draw surface or ground water treat the water and clean water is provided through tap. Each villager was given a card and on inserting the card, each villager gets around 20 liters of water per day. M/s ONGC has implemented the project on the condition that M/s ONGC will only bear the capital expenditure (only the cost of water ATM machine) and one year AMC and subsequently the village has to maintain the water ATM. The land required for installing ATM was identified by the villagers, electricity was provided by village/ temple authorities. After lapse of one year the expenditure towards O &M cost/ AMC cost of the water ATM had to borne by the village. Reported that water ATM installed at Antharvedi Devasthanam was operational for one year and afterwards no one has taken responsibility and currently it is not operational. While the water ATM in the village is not put to use. During committee visit, both the water ATM's were not in operation.

The process flow followed by M/s ONGC for CSR is given in the below image. Further two case studies are given as Annexure-X. Page 34 of 39 35 Inspection Report in the matter of OA 175/2020 (SZ) Image: Process flow followed for CSR projects at ONGC Page 35 of 39 36 Inspection Report in the matter of OA 175/2020 (SZ) Image: CSR abstract of Rajahmundry asset from 2018- 2021 IX Conclusions and Recommendations Hon'ble NGT vide order dated 19.01.2022 directed the committee to inspect the units and verify the compliance status of the units. Committee observed that as compared to previous visit, there are improvements but units are yet to achieve compliance and few serious & significant violations were observed by the committee.

Inspection Report in the matter of OA 175/2020 (SZ) i. Currently, Tatipaka GCS is operating the ETP and unit is testing the quality of treated effluent as to whether it is meeting the discharge standards or not and after ensuring that unit complies with discharge limits, treated effluent is discharged through ED wells. Unit has maintained records on the quantity of effluent generated, characteristics of effluent at inlet & outlet of ETP and quantity of effluent disposed through ED well. However unit has not taken adequate measures in handling the oily sludge, slop oil and washings. Spillages or oil deposition near the ETP area is not fully cleaned. Effluent oily sludge stored in the old ETP shall be treated and old ETP shall be dismantled. Sludge stored in the sludge tank shall be disposed. Unit shall ensure that it will comply with Hazardous Waste Management Rules, 2016 and dispose the hazardous waste within 90 days fromthe date of generation.

ii. Kesanapalli ETP is handling around 1800 KLD of effluent against the consented quantity of 600 KLD and is having two ETP's. Old ETP was not properly operated however treated effluent is meeting the discharge limits for ED well disposal. New ETP is handling 1500 KLD of effluent and treated effluent is disposed in the sea with existing marine outfall pipeline of 60m against consent condition of ED well disposal. Outside the unit premises water stagnation was observed and TPH (Total Petroleum Hydrcarbons) is around 971.17 mg/L which indicates that effluent may be leaking/ discharged outside the unit premises or runoff from old ETP area has stagnated outside the unit premises. Sediment samples collected around old ETP contains TPH of 319mg/Kg indicating mixing of spillages on the ground. Unit shall ensure that ETP is properly operated, effluent is disposed as the per conditions stipulated in CFO and ensure that no effluent is discharged outside the unit premises. Sludge shall be properly managed and prevent the spillages. Kesanapalli GGS shall immediately stop disposal of treated effluent by marine outfall near the coast and dispose the treated effluent as per the conditions stipulated in CFO issued by APPCB iii. Laying of new pipe line in CRZ area by Kesanapalli GGS does not have prior CRZ clearance from Ministry and Consent approvals from APPCB. Kesanapalli GGS shall Page 37 of 39 immediately approach concerned authorities for obtain prior permissions for the new pipeline.

iv. Effluent generation is around 1800 KLD and ETP at Gopavaram is having capacity to handle 600 KLD of effluent. Hence untreated effluent is discharged outside the unit premises. Water present in the storm water drain and in unlined lagoon contained TPH of 731.78 mg/L and 185.53 mg/L indicating the presence crude oil/ effluent in the sample. Sediment samples collected from Gopavaram GGS contains high concentration of TPH in the range of 644.07 mg/Kg to 30,698 mg/Kg which indicates that oily sludge is dumped on the ground. Since unit is not having ETP of adequate capacity, untreated effluent is discharged through ED wells. Unit shall take measures to augment the treatment capacity and ensure that only treated effluent is discharged through ED wells. Till the ETP capacity is enhanced, unit shall restrict its production so that quantity of effluent generation is proportionate with ETP capacity.

v. Whenever any oil spills/ leakages takes place within the unit premises or whenever sludge is carried with runoff, unit is covering it with fresh soil and not taking measures to clean up. Units shall ensure that during any untoward incidences of oil spill/ leakages, unit shall take measures to remove the entire quantity of spills/ leaks and scrap the underlying soil and store it in sludge tank and dispose the same along with oily sludge.

vi. During rains, the first flush of rains is likely to carry the pollutants into adjacent area and it is essential for the industry to have facility to lift the first flush of rain water and treat the same in effluent treatment plant.

vii. During previous committee visit it was observed that thick oily sludge was present in the storm water drains. Currently all the units have cleaned the drains and they were in dry condition. Units have also devised plan for periodical cleaning of drains. However units have not maintained records on the quantity of sludge removed from drains and 38 mode of disposal of the silt/ sludge. Unit will take measures to install oil catchers in the drains located near process area & ETP. Based on the characteristics of the silt/ sludge present in the drains, units will safely dispose the same.

viii. There was no odour nuisance during this visit and ambient air quality in the installations and in the villages is meeting the National Ambient Air Quality Standards. Committee observed huge flames from flare stack at Tatipaka GCS. Units have not maintained proper records on the volume of the gas handled in the flare stack. It was reported that unit has already proposed to install new flare stack at Tatipaka and Kesanapalli. Unit may submit time bound action plan for replacement of flare stacks.

ix. The unit has obtained consent from APPCB during 2015 and subsequently the consent is renewed (online consent monitoring and management system) but however post 2015 due to ageing of wells the quantity of produce water is increasing and there by the quantity of effluent generated is also increased. The actual quantity of effluent generated is higher than the quantities stipulated in the CFO. All the stacks installed in the installations are not covered under the purview of the Consent order. For instance stack installed at TEG unit is not included in the consent order. M/s ONGC shall ensure that every installation obtains Consent For Operation from APPCB under the Water Act, 1974 and Air Act, 1981 for the actual quantity of products manufactured, actual quantity of wastewater received and include all the stacks installed in the unit.

x. Committee observed that M/s ONGC are utilizing the CSR funds for environmental & social development activities and other essential activities identified by the District Magistrate/ Corporate Head office/ Public representatives/ registered NGO's.
