Sir,

We write with reference to your letter no: RO-NE/E/IA/AS/MI/59/L69-7L dated:05,07.201,6 on above subject. In this connection, please find given below the compliancestatus of the points recommended based on your monitoring visit at sites of OlL between7tr fune to 14tr fune, 2016 are as follows:

L Restoration work at several drillingproject sites is yet to be carried out.Site abandonment plan should beimplemented for the drilling site inaccordance with the applicable IndianPetroleum Regulations as stipulatedin the condition. Site abandonmentand Restoration plan should besubmitted to the Regional Office forall blocks.

Restoration jobs of completed drillingwells are done as per policy.Well Site abandonment and Restorationplan are enclosed as Annexure-l

2 The operation of Pengry site istemporarily suspended and the well isin "Shut in" condition. No restorationwork at the project site has beencarried out,

Restoration/Reclamation job at Pengrysite (Location EA) has been done,photographs enclosed as Annexure-ll.

nJ Based on CSIR-IITR results, thechemical caustic soda is classified as a

in the drilling fluid used in our drillingoperations. An experimental test reportcarried out in OIL's chemical laboratoryis enclosed herewith as Annexure-lll,where it shows that to maintain PH levelat maximum point i.e. 9.5, the requiredconcentration of caustic soda (NaOH) is10 mg/L. Therefore we confirm thatmore than 10 mg/L Caustic Soda is notbeing used by OIL.

4 The environmental statement for eachfinancial year ending 31 't March inForm-V along with the status ofcompliance of environmentalconditions should be sent to therespective Regional Offices.

The environmental statement for thefinancial year 20L5-20L6 in Form-Valong with the status of compliance ofenvironmental conditions has been sentto the Regional Office, Shillong videletter No: S&E/E/ZLB /L54L datedL6.08.2016.

Copy of the same is enclosed asAnnexure-lV

5 The consent to operate and forHazardous Waste authorization is yetto be issued by Assam PollutionControl Board.

Matter regarding Consent to Operate andHazardous Waste authorization has beentaken up with Pollution Control Board ,Assam. To this effect a letter has beensubmitted for issue of Hazardous Wasteauthorization vide our letter No,S&E /E / 26 / 7645 dated 3 1.08.20 16.

Regarding Consent to operate certainclarification were sought by PCBA towhich OIL has submitted the reply videletter No. S&E/ S&E/E/20/L303 dated19"08.2016

B The proposed project to furtherreduce the gas flaring and to minimizegas flaring by adopting newtechnology & methods may beimplemented early so that flared gascan be utilized for power generationby installing micro -turbines & screwcompressors.

Present average gas flare in Assam andArunachal Pradesh is 0.22 MMSCMD. Gasproduced in High pressure system isdirectly transported and supplied toconsumers without any flare. HoweverLow pressure gas produced requirescompression facility for onwardtransportation. OIL has its owncompression facilities in different areafor the purpose. In addition OlL hashired compression services in someinstallations. In recent times this hiredcompression service has been extendedto Heveda and Baghjan area andsuccessfully commissioned in fune, 2016.These compressors are capable ofcompressing gas from L.0 Kg/cm2 todelivery pressure of maximum 25Kg/cmZ. With this service in Heveda andBaghjan area 60,000 SCMD gas has beenmonetized and flare reducedaccordingly. The contract has theprovision of putting up additionalcompressor in case of increase of lowpressure gas production in these areas.OIL has commissioned new SCADAsystem for on line monitoring of Gasproduction, utilization and flare. Withthis SCADA, real time monitoring ofintegrated gas management systemincluding various control systems inconnected production installationsacross the fields in Assam and AP isbeing done and action taken foroptimum use of resources to keep theflare at minimum. Accordingly action hasbeen initiated for power generation byinstalling micro-turbines.

I The project has suffered with break inproduct line causing huge sludge isspread in Shalmari OCS. The sludgeshould be removed for recovery of oil

1_0 The Public Liability (Act) Policy:200402/45/75/7200000002 had avalidity period of 0L/A4/20L5 to31,/03/20L6, therefore, the policy haslapsed.

The policy has been renewed and copy ofthe same is enclosed herewith asAnnexure-VIL

11, The formation water of Moran OCShas substantial oil content, thereforeOWS treatment system needs to berevamped.

The dosing rate of De-oiler chemical hasbeen adjusted in consultation with R&Ddeptt. of OIL followed by Carefulskimming of the seperated oil. As a result, the oil content of formation water hasdecreased from LLo/o to 1-O%(Reportenclosed as Annexure-VlII).

12 During visit of Mechaki area, itobserved that OIL sludge is spreadaround production storage tanks atQPS and existing storage pits andponds need to be reclaimed.

Oil sludge has been picked up and areahas been cleaned. Since the existingtanks were leaking two nos. new tankshave been installed and commissioned.Photographs enclosed as Annexure-lX.

13 The project of QUIPPO is required torevamp the solid waste disposal lineat drilling well sites to avoid a spreadof waste drill cuttings and mud beforereaching to disposal pits to helpimproving the house keeping furtherat sites.

Revamping of Solid waste disposal lines/ nullah has been completed. Spread ofsolid waste has already been removedand dumped in the lined pit.Photographs after revamping of solidwaste line with clean area below the lineare enclosed as Annexure-X.

14 During visit of Bhogpara OCS, it wasobserved that formation water hasvery high TDS,TSS and OlL content,not suitable to inject in the deepwells. The treatment system forformation water needs to berevamped,

Vigorous skimming of formation waterwas carried out and water samples wereanalyzed. It has been observed that theoii content has come down to aacceptable level. Efforts are on to bringdown the TSS level.

Analysis report enclosed as Annexure-Xl

15 During visit to drilling DGY well, itobserved that road inside the drillingarea needs improvement. The storagepits of drill cuttings are almost full.The project must carry out waterqualiW analysis for the surroundings

Drilling operation at Loc: DGY had beencompleted and rig was released on18/07120L6. Water sample has beencollected from the effluent pits and thesurrounding water bodies of Loc: DGY.No abnormalities were found in the

In Makum OCS , Ex-Situ Bioremediationfor oily sludge of approx volume 800 m3has been initiated through existingcontract signed with M/s OTBL videemail dated 04.08.2016.

Plantation of flowering plants forbeautification in viciniLy of IM's officewas advised. Saplings for the same havebeen procured and planted in suitableareas in the vicinity of IM's office.(Photograph enclosed as Annexure XIII)
