Oil Spill Response Plan and TIER 1 Compliance to NOSDCP

Page 1 of 4| Annexure-4: Oil spill response plan for Tier I compliance as per NOSDCP

Sensitivity: Internal (C3)

Executive Summary Based on the issued Terms of Reference (ToR) by Coast Guard, Delhi, who has decided that all the Ports and Oil Companies should have approved Oil Spill Contingency Plan as per NOSDCP-2015. M/s Environ Software (P) Ltd, Bangalore carried out Oil Spill Modeling, Risk analysis studies and response plan, Marine Atlas all along the coasts of Andhra Pradesh, East coast of India. M/s Vedanta Limited (Carin oil & Gas) has already procured and comply with pollution control equipment’s to contain any oil spill. This Oil Spill Contingency Plan (OSCP) is prepared based on the output of various studies consisting of Hydrodynamic modeling, Oil spill modelling, Environmental sensitive index mapping and Net Environmental Benefit Analysis Hydrodynamic Modeling: • Preparing the input data for model. • Calibration and Validation of hydrodynamic model with the available tides. • Numerical runs were carried for various hydrological conditions for predicting the tides and tidal currents in the East coast of India. • Flow model studies were carried out using the Hydrodyn-FLOSOFT, with local refinement in the area of marine facilities incorporation of marine sensitive areas and existing marine structures and facilities in the area of influence. For all possible marine facilities, spring and neap tide conditions was simulated. • Flow modeling will be carried for entire year combined with seasons. Oil Spill Modeling: • Sensitivity mapping of the study area was prepared considering environmental, ecological, social, economic and other factors. • Risk assessment carried out to identify potential oil spill scenarios software. • Crude oil weathering and dispersibility study was considered to provide necessary data dispersant efficacy and to optimize oil spill response plans. • Generation of data such as: tidal current, ocean current, local winds and others was gathered. • Oil spill modeling considering worst case scenarios was prepared. • Oil spill response action plan & strategies as per NOSDCP-2015 and latest requirements; Tier-1, 2 & 3 arrangements were compiled. • Discussion of OSRP with site team and Training was carried out. Environmental Sensitivity Index mapping • Sensitivity Index Mapping was prepared to develop action plan against oil pollution and protect the shorelines and its clean-up requirements. • Identification of the most sensitive site and resources potentially exposed to oil spills due to operation and drilling activities. • The sensitivity maps cover the entire coastline of the susceptible area including inlets and islands. Mapping the sensitivity of the terrestrial environment surrounding the installations and pipelines was also considered. • Maps (including the mapping of coastal sub tidal habitats) was prepared to support the application of dispersant by providing information on the potential impact of dispersed oil in the water column. • The Environment Sensitivity Index Mapping range from 1 (low sensitivity) to 10 (very high sensitivity), integrating the 1. shoreline type, its grain size and slope which determines the capacity of oil penetration and/or burial on the shore, and movement, 2. Exposure to wave and tidal energy which determines the natural persistence time of oil on the shoreline and 3. General biological productivity and sensitivity. The 10 levels of Environment Sensitive Index were color coded from cool color to warm color indicating

Page 2 of 4| Annexure-4: Oil spill response plan for Tier I compliance as per NOSDCP

Sensitivity: Internal (C3)

increased sensitivity. Each color corresponds to a particular type of coast, allowing identification of the type and relative sensitivity at a glance. • The mapping of biological resources considers the seasonality and life stages present, i.e. breeding, spawning, hatching, migration etc. Depending on the information available, the species concentration information is simple (presence/absence) or more detailed (1. no information, 2. Rare, 3. Common, 4. Abundant and 5. Highly abundant). The use of the four seasons, spring, summer, autumn and winter was avoided to prevent confusion between northern and southern hemispheres. • Since some of the sub-tidal habitats (coral reefs, sea grass beds and kelp beds) are essential for the coastal marine biodiversity, they were also considered and localized while preparing the maps. • Sensitive socio-economic features are mapped to include the non-living resources that may be directly injured during oil spill. These features are grouped into various categories like 1. subsistence, artisanal and commercial fishing, and fishing villages, 2. aquaculture, 3. water intakes like salt marsh plant, desalinization plant, aquaculture and salt production and industrial use, 4. Tourism and recreation areas like hotels, restaurants, marinas, beaches, recreational fishing, diving, etc., 5. Port including the activities and infrastructures, 6. Industrial activities relying on maritime transport activities, and 7. Cultural sites like archaeological, historical, religious, etc.

NEBA Studies NEBA studies is prepared to evaluate and compare the oil spill response options against oil spill response plan. In addition, the NEBA intend to support spill response efforts, in the unlikely event of a spill incident, and provide a basis for acquiring approval for the use of Oil Spill Dispersants with Indian Coast Guard on the matter. The emphasis of the NEBA is on a structured qualitative analysis to identify response options which offer a net environmental improvement over the natural attenuation as a baseline. It is not intended to be a quantitative analysis. The purpose of the analysis is to help to form informed decisions. In summary, NEBA is a holistic approach that: • Consider potential impact to the resources of concern. • Consider how well the resources (such as, marine sensitive areas, tidal flats, islands and coastal areas) can be protected with the available response techniques at the time of a spill.

Ravva Operations of Cairn Oil & Gas Vedanta Limited, as a responsible upstream company gives high importance to health, safety and environment As the upstream industries are exposed to risks of oil spills, Cairn has prepared contingency plans to mitigate any emergencies arising out the operations involving the best of technologies and services available in the industry. The key to effective management of an emergency is to have trained manpower, response resources and pre- established organizational arrangements for mobilizing and responding for mitigation without much loss of time. The plan is to primarily deal with oil spill emergencies resulting from exploration, production and transportation of crude oil from the Ravva offshore facilities and include the surface facilities viz., platforms, drilling rigs, vessels and subsurface pipelines and all other associated infrastructure required for the production operations This OSCP is structured based on the directives and guidelines of Indian Coast Guard and general guidelines of IPIECA and primarily divided into three sections 1. A strategy section defining details of operational and environmental risk assessment, strategies for oil spill response, response plan organization of the Vedanta Cairn aligned for oil spill response and associated activities like media briefing, training and documentation etc.

2. An action plan describing how to activate the OSCP in terms of notification, mobilization and response decisions in case of dynamic situations of oil spill hitting various coastal resources. Operational planning and coordination among other participants, stakeholders and monitoring of the response actions till the close out of the activities are covered in this section. 3. A data directory compiling the details of location maps and charts, equipment and services available for response and technical data base on the equipment, deployment methodology and supporting documents for response. The Report consists of four parts including Main Part Main Part: Oil Spill Contingency Plan. The report consists of the following sections 1. Strategy Section: This section consists of oil spill risk assessment, objectives, strategies, and details of available response equipment’s. This section discusses the possible oil spill scenarios, the ways and means to respond effectively to minimize pollution. This part is covered between Chapter 2 to Chapter 6. 2. Action and Operation Section: This section includes specific instructions for responders once the spill occurs, on what to do and how to do, for each oil spill incident. This is to ensure that emergency action initiated by the responders are addressed in a promptly and orderly manner. This part is covered between Chapter 7 to Chapter 10. 3. Data Directory: This section includes information on statutory regulations, area of operation, training and competence, weathering data on ADIOS, Mud flat shore cleanup techniques, OSD Specifications etc.

Agreements with external agencies While the company’s own facilities and the response facilities with the nearby operators can help tackle small and medium spills, it is inevitable to depend on external agencies for larger spills for longer periods. Apart from the facilities of Coast Guard available at the nearby region, additional facilities of external agencies would also be sought for large spills. A few such Oil Spill Response Organizations (OSROs) are available globally among which the service of Oil Spill Response Ltd (M/S OSRL), a nonprofit, industry supported OSRO in Singapore are considered to logistically relevant and technically competent. The services of M/S OSRL are also sought by several other operators in India. Vedanta Cairn Oil & Gas took associate membership with M/S OSRL for support in case of spills of larger magnitude and inclusive of offering equipment for mobilization and help of experts for technical coordination and guidance.

General strategy of deployment of resources for various types of spills is given below:

Tier I <100 tons Use Local Spill kits <700 tons Deploy Cairn Facilities; Engage other operators and Coast Guard Tier II <10000 tons Deploy Cairn Facilities; Engage other operators and Coast Guard Tier III >10000 tons Cairn facilities, other operators, Coast Guard and M/S OSRL

MARINE ECOLOGY STUDY – EXECUTIVE SUMMARY

As a part of M/s Vedanta Limited (Division: Cairn Oil & Gas) efforts to conducting environmental reconnaissance studies close to their offshore installations in the KG Basin off Surasaniyanam Village, Uppalaguptam Mandalam in the East Godavari District, Andhra University undertook a detailed study on the hydrobiological conditions of that area in December 2018 coinciding with post south-west monsoon conditions. The investigation was held at the same 37 stations chosen earlier which represented a wide spectrum of habitats such as shoreward locations (1-9), the core area (10-33) and four Reference points (RC1, RC2, RF1 and RF2) of which the last two are in deep water (depth 26-43m), maintaining a gradation of depths (5.2m and 43m) overall. As with earlier studies, the scope of Dec-18 investigation also related to monitoring biological attributes (phytoplankton, zooplankton, macrobenthos, and fisheries) along with conventional water quality characteristics at the selected locations closer coast (0.5 km from the shore) and up to ~17km in the sea. The observations were made for 6 days (3-9 December 2018) during daylight hrs when the sea state was comparatively stable; wind direction predominantly northeast and the prevailing current southerly. Surface and sub-surface (Niskin) seawater samples (including mid-depth) were collected from all 37 sites for estimating conventional variables such as water temperature, salinity, turbidity, pH, inorganic nutrients (nitrogen, phosphorus and reactive silicate) and the same analysed following standard protocols. Studies on phytoplankton consisted of species composition and their numerical abundance. Zooplankton analysis included identification of taxonomic groups and diversity, numerical enumeration of standing stocks to assess secondary productivity. Seabed life (dredge hauls and grab samples) was assessed (in terms of diversity and richness) to elucidate faunal assemblages at the community level of organization in relation to sediment texture and structure for drawing (possible) future comparisons. Estimation of major, minor and trace elements in seafloor sediments, seawater and marine biota was carried out at for all locations. Estimations were also made on Total Petroleum Hydrocarbons at selected locations for both water and sediment samples close to the oil platforms

Fig.1: Based on water quality characteristics, the study sites (1-33, RC1, RC2, RF1, RF2) could be divided into 3 regions Hydrographical conditions: Based on water quality data (Table 1), it is concluded that the environmental conditions in the Sea off S. Yanam are characterised by relatively low salinity (mean 29.96) implying moderate influx of freshwater from River Godavari (the Vainateyam Branch after cessation of heavy floods) as against ~34 parts noticed during summer months when there is hardly any river flow into the sea. Overall, this period is marked by low sea surface temperature, improved secchi disc transparency, low turbidity, moderate amounts of dissolved oxygen, inorganic nitrogen, phosphorus and low levels of silicate and appreciable DON influencing the chlorophyll levels. Comparatively, the coastal waters revealed high turbidity, inorganic nitrogen, phosphorus, silicate and chlorophyll as against their low concentrations offshore presumably because of efficient mixing on the high seas. Observations have shown that the water column regime could be divided into three major regions namely the coastal area, the open sea sites and the transitional water suggesting presence of noticeable horizontal gradients (see Fig.1). Based on the multivariate analysis (normalisation and hierarchical clustering) performed on the water quality data (using PRIMER v7 - the Euclidean distance based cluster analysis) clearly showed three distinct regions namely the coastal locations i.e. 1-9, 11, 14, RC1 and RC2; transition locations 10, 12, 13, 15-18, 26, 28-33 and the open sea sites 19-25, 27, RF1 and RF2, though some overlapping exists.

Seafloor Sediments: During the present study, detailed analysis of sand and mud (silt plus clay) and organic matter was carried out for all 37 locations (categorised coastal, transitional and open sea). Table 2 contains summarised information (range, mean and SD) on sediment nature and organic content for the three regions described above:

Table 2: Summary of sediment characteristics Sediment Coastal Transitional Open sea characteristicsStations investigated 1-9, 11, 14, RC1, 10, 12-13, 15-18, 26, 28- 19-25, 27, RF1, Sand (%) (0.09RC2-17.17) (0.0933-6.26) (0.16RF2-5.32) 8.35±5.6 2.35±2.24 2.74±1.97 Silt and Clay (%) (82.83-99.91) (93.74-99.91) (94.68-99.84) 91.65±5.6 97.65±2.24 97.26±1.97 Sed.

From the findings presented above, it is clear that 3% organic matter remained high (mean 0.98%) for the 1% 4% 12% open sea locations compared to transitional locations 40% (0.79%) and coastal locations (0.59). This pattern appeared to agree well with the nature of sediment. 40% For example, in coastal locations the sediments were relatively sandy (mean 8.35%) in comparison to open sea. Silt+clay recorded highest (97.26%) at the open Centrales Pennales sea locations than coastal sites (91.65%). The Dinophyceans Cyanophyceans predominant reason for the relatively high mud levels Fig.2: Phytoplankton group abundance Dec-18 at most places could be related to the flow from Godavari and Krishna Rivers opening into the sea further north and south in this area. In summary, sediments in the study area could be classified into three categories as coarse, soft and mixed types corresponding to shoreward locations, the open sea and the central (core) areas respectively.

From the list of species encountered, it is evident that the phytoplankton in the coastal waters off Ravva region is quite diverse and is dominated by diatoms (bacillariophyceans). During the study, phytoplankton (mean) numerical abundance ranged between a low 152 nos.ml-1 at st.28 to 349nos.ml-1 at st. 19, the overall mean being 239 nos.ml-1. Fig.2 shows relative abundance in the total population.

Phytoplankton community structure was determined based on Bray-Curtis similarity implemented in PRIMER through hierarchical clustering and group average linking followed by multidimensional scaling (MDS). Fig. 3 displays results for the 37 stations. From the resulting dendrogram, it was possible to define the locations into 3 groups determined at 45% similarity. Groups of stations confirmed by this procedure are: Group I consisting of stations 1-10,14,15, RC1 and st.RC2 representing the coastal region, Group II (sts. 11-13,16-18 and 20-33) the intermediate locations and Group III consisting of st.19, RF1 and RF2 representing the seaward locations. ANOSIM (Global R: 0.782 at 0.1%) indicates that these three areas are significantly different in the composition and abundance of phytoplankton. Phytolankton diversity was measured for all 37 locations. At each location, the number of phytoplankton species (S), mean numerical abundance (N), diversity (Margalef, d, Shannon-Wiener, H’ and Evenness J’) for all 37 locations were calculated. Overall, while species richness and diversity was high in coastal and intermediate locations, seaward locations were relatively less diverse. To sum up, the observations showed moderate phytoplankton activity in surface water at Ravva basin during this part of the year. Relatively Low abundance in the coastal and intermediate locations indicated rather poor productivity. Chlorophyll content was also relatively low evidently due to low phytoplankton abundance

Zooplankton: Similar to earlier studies (e.g. November 2017), copepods represented by 45 species were the most abundant and species rich MSP (mesozooplankton) functional group. In terms of species richness, they constituted 67% of total MSP taxa recorded in the coastal waters of Bay of Bengal within the Ravva oil field. Small sized copepods (≤1mm size), Paracalanus indicus, P. aculeatus, Acrocalanis longicornis, Oncaea sp., Corycaeus sp., and Oithona sp. were the most dominant forms with assemblage specific distribution. Differential distribution of calanoid and poecilostomatoid copepods were mainly responsible for the observed changes in mesozooplankton assemblage patterns. Meroplankton was mainly constituted by bivalve veligers, gastropod veligers, and larval decapods (mysis stage). This could be due to the proximity to molluscan bed in the immediate vicinity of Godavari estuarine complex. Discrete mesozooplankton communities characterized inshore area, core area of oil exploration activities, and the offshore waters in and around the Ravva oil field in the Krishna

similarity and group average linking was carried out to classify the assemblages/clusters using PRIMER v7. Based on the analysis, the macrobenthic fauna at the study area could be separated into two major groups (also read Assemblages) at 12% similarity (ANOSIM Global R: 0.845 at 0.1%) reflecting water / sediment quality for this area. Group I (shore-ward, Ave. depth <9m) consisted of 21 stations (1-16, 23. 24, 27, RC1 & RC2). Group II (relatively Deep water, ave. depth 17.8m) with 13 stations (17, 18, 20-22, 26, 28-33, RF1, RF22); and St.19 was as an outlier. It is noteworthy that significant Table 3: Macrobenthos epifaunal diversity summary (P <0.01) differences were noticed in the sediment nature (sand, silt+clay and character S N d J' ES(100) H'(loge) organic matter levels) between the min 5.0 7.0 1.2 0.6 5.0 1.0 shoreward (Group - 1) and offshore max 25 91 5.7 0.98 25 2.78 (Group - 2) locations evidently as a mean 11 36 2.9 0.8 11.1 1.86 result of the prevailing gradients in the environment especially salinity.

In addition to the samples for epifauna collected using a naturalist dredge described above, as many as 74 grab samples were collected Phase IV: December 2018 INFAUNA (2 each at 37 locations) meant to cover the infaunal taxa (living buried in the sediment). Nearer shore (depth <10m), while the sediments were essentially sandy, further offshore their texture changed from silt to clayey mud. These features greatly affected the fauna living buried in the seafloor sediments at Ravva field.

Cluster analysis was performed on the infaunal abundance data. Bray-Curtis similarity and group average linking was used to classify the 37 stations into assemblages/clusters using PRIMER v7. Based on the analysis, the infauna could be separated into two major groups (also read Assemblages) at 43% similarity (ANOSIM Global R: 0.625 at 0.1%) (Fig.11). Group I (shore-ward) consisted of 14 stations (1-9, 12-13, 15, 27, RC1) and represented somewhat coarse sediments nearer shore. Group II contained 11 transitional stations (10, 14, 16, 17, 19-21, 23-25, RC2 marked in green) of mixed sediment category and 11 seaward locations (18, 22, 26, 28-33, RF1, RF2) where the sediments are soft.

The general paucity of fauna is undoubtedly due to the soft nature of the sediments that did not promote establishment of steady-state populations.

Fisheries: Altogether 13 taxa were encountered which represented the composition of finfish (11 taxa), a single crustacean and a cephalopod during the trawling operations carried out on four occasions within the Krishna-Godavari basin. Among the thirteen taxa recorded, only Stolephorus sp. (Anchovy) dominated all through showing its presence at Stations 1, 3 and 4. At Station 1, this species was found in large numbers (63kg). Next in order were Opisthopterus sp. (Tardoor) which showed 17kg at Station 3, followed by Lepturacanthus savala (Smallhead hair tail) (12kg) and Hilsa kelee (Keele shad) (11kg), all of them at Station 3. Three species of finfish namely Chirocentrus sp. (Wolf herring), Lepturacanthus savala (Smallhead hairtail) and Pampus chinensis (Silver pompret) were present at two stations. Other species namely Hilsa keele (Kelee shad), Johnius trachycephalus (Croaker fish), Opisthopterus sp. (Tardoor). Otolithes ruber (Tigertooth croaker), Pampus argenteus (White pomfret), Decapterus sp. (Scad), and Therapon jorbua (Tiger perch) made their appearance once in each station. A cuttlefish (Sepia sp.) also occurred at stations 1 and 4 while the shellfish Penaeus sp. showed its presence only at Station 2. Table 4 shows regions where the experimental trawling took place together with volume of catch on each occasion.

The fishery resources in the present survey, represent only few important commercial fish namely White Pompret, Silver Pompret, Anchovies, Perches, Shrimps and molluscans which corroborate well with the reports of ONGC (2016) at KG baisn but they were found to occur very sparsely at all four stations of the present study. Overall, the present data correlates well with that of CMFRI (2018) and FSI (2014) demonstrating the distribution of perches, decapterids, cephalopods and anchovies at Lat 160.

Total Petroleum Hydrocarbons: In the present investigation, total petroleum hydrocarbon concentrations together with oil and grease were analysed in the seawater and sediment samples collected from 10 locations in Krishna-Godavari (KG) basin nearer to the oil drilling installations. These locations were divided into control (CON1), active (RBCOP, RCCOP, RDCOP, RECOP, RFCOP, RGCOP, RHCOP), oil loading (SBM) and inactive (RACOP) areas. Table 5 contains the findings.

The total petroleum hydrocarbon concentrations observed in seawater and sediment samples at all the stations of the KG basin of CAIRN / VEDANTA are very low and far below the standard limits prescribed by ATSDR (1999) indicating no oil pollution or toxicity. Oil and grease values are not detectable in seawater but traces are present in sediment samples indicating very low contamination.
