Mapping the shoreline risk assessment of oil spill in the eastern region of Qeshm channel

The northern shores of the Strait of Hormuz constitute one of the most diverse shorelines in the Persian Gulf, characterized by both utility and environmental richness. Situated in the Qeshm channel, which hosts the largest mangrove habitat, major industries, and commercial port, these shores are subject to the occurrence of oil spills, posing potential substantial harm. This study employs General NOAA Operational Modeling Environment (GNOME) and numerical modeling to assess the potential risks to shorelines from hypothetical oil spills, considering the distinctive features of the shores and their environmental sensitivity. The results indicate that high-risk levels are not excessively prevalent overall and are confined to approximately 24 km. The shape of the channel and hydrodynamic conditions highlight the eastern sector of the Bandar Abbas urban area as particularly susceptible to oil spill entrapment. The findings indicate that high-risk areas are predominantly located away from industrial-oil shores and primarily consist of muddy shores. Therefore, internal strategies of Oil Spill Contingency Plan (OSCP) of companies are deemed insufficient and necessitate comprehensive planning initiatives.

Irrelationship between live coral cover and reef fish: an interim study of marine habitat dynamic on Mandangin Islands

Most coral reef ecosystems with high coverage of living coral would escalate the reef fish abundance and species richness as one of the correlatable communities to the coral reef. However, reef fish could only utilize one of the coral reef ecosystems to provide to the reef fish community that still withstand and adapt to those conditions. This study aims to assess the coral reef ecosystem quality on Mandangin Islands and the correlation between the benthic substrate to the reef fish structure. Coral reef ecosystem was assessed using Line Intercept Transect and Underwater Visual Census. A linear model or regression analysis was built to identify the key predictors driving factor in the ecosystem. Rock, Sand, and Rubble are the highest benthic substrate around Mandangin Islands. Reef fish have a high abundance along the observation site with exhaustive trophic level, high major functional group, broad bodied size with high abundance small to moderate bodied-size. Rock has a positive correlation to reef fish abundance; Sand has possibilities to escalate species richness, whereas live coral negatively correlates to reef fish. Historically Mandangin Islands contained a healthy coral reef ecosystem that degraded after years, yet reef fish withstand and adapt to the Mandangin Islands’ degraded coral reef ecosystems. Rock is coral that loses several of its function, especially as direct nourishment. This study showed that reef fish should be considered as one of the primary data to strengthen the decision-making of Integrated Coastal Management and Oil Spill Contingency Plans by the Oil and Gas Company.

Revitalizing Community Participant: Overcoming Challenges in the Aftermath of an Oil Spill Disaster Preparedness in Kampung Tanah Merah Baru, Teluk Bintuni, West Papua

This research aims to investigate the community profile and challenges faced by Tanah Merah Baru Village in Teluk Bintuni, West Papua, following diesel fuel spill disasters associated with transportation activities near an LNG exploration company operation. The study employs a comprehensive research methodology, combining quantitative surveys, qualitative interviews, and focus group discussions with community representatives and a company's oil spill response team. Data was collected and analyzed by using descriptive statistics and factor analysis through IBM SPSS Statistics Version 27 software. The findings reveal that the community profile is influenced by social, economic, and environmental factors. Additionally, there is a low level of awareness and community participation in handling diesel fuel spills and implementing the Oil Spill Contingency Plan (OSCP). Notably, variations exist in the perceptions and attitudes towards diesel fuel spills among community members who have previous exposure to the company’s operational environment. To enhance the community's profile and resilience, targeted efforts are required to provide information and training, thereby improving preparedness and response capabilities in handling diesel fuel spills effectively in Tanah Merah Baru Village, Teluk Bintuni, West Papua.

Effects of Oil spillage on the Socio-economic welbeing of Artisanal Fishermen in Akwa Ibom State, Nigeria

This study assessed the effect of oil spillage on the socio-economic wellbeing of artisanal fishermen in Akwa Ibom State, Nigeria. Primary data were obtained from 200 artisanal fishermen using multi-stage sampling procedure and analyzed using descriptive statistics and Likert scale ratings. Results showed that the mean age of fish farmers in the area was 40 years and majority (57.0%) were married. Fishermen were quite educated (93.5%) with a mean of 12 years of educational attainment, The mean household size, farming experience and income were 6 persons, 9 years and N600,000, respectively. The major causes of oil spillage were; drilling of oil well, illegal facilities, spill from storage facilities, corrosion of oil pipelines, faulty production equipment, natural disaster, leakages from oil tank, oil theft, shipping accidents, cleaning of oil tankers on the high sea and spills from vandalized oil pipelines. Findings showed that oil spillage reduced the income of fishing household, led to food insecurity, deteriorated the health status of fishermen, polluted the environment, led to migration of fishermen out of the affected areas and resulted in abandonment of artisanal fishing operation for other livelihood operation. Findings further showed artisanal fishermen’s coping strategies to include; migration to other communities, livelihood diversification, extension of fishing time, involvement in community and individual level savings, attending enlightenment programs on coping with effects of crude oil spillage and frequently changing the timing and location of fishing trips. This study therefore recommended that the federal government should implement an aggressive national oil spill contingency plan which includes the cleanup of polluted areas and payment of reparations to affected artisanal fishermen in Akwa Ibom State.

Strategic environmental sensitivity mapping for oil spill contingency planning in the Peruvian marine-coastal zone

Major oil spills can cause significant impacts on marine-coastal zones, particularly on areas with a high oil spill risk, which combine a high oil spill hazard—high likelihood of oil stranding at high concentrations, and a high environmental sensitivity—high concentration of highly sensitive ecological and socioeconomic resources. In this context, a straightforward multicriteria methodology is proposed to determine the second factor of the oil spill risk, namely the strategic environmental sensitivity (SES), in 68 sectors covering the entire Peruvian marine-coastal zone. The methodology comprised the weighted integration of physical, biological, and socioeconomic sensitivity indicators based on their relevance in surface marine oil spills and the Peruvian ecological and socioeconomic context. As a result, relative SES levels from very low to very high were assigned to the sectors. To demonstrate the SES applicability, an oil spill risk assessment at a screening level was performed in a selected sector with current oil production activities. The oil beaching likelihood of worst-case discharge scenarios modelled for January 2021 was used to determine an overall screening oil spill hazard level in the selected sector, while a matrix relating the SES and hazard determined the screening oil spill risk. The results can be used as a decision-support tool to enhance the oil spill contingency planning in Peru or be used in other relevant processes such as the integrated coastal zone management, the marine spatial planning, or the contingency planning of other liquid contaminants. In addition, the proposed methodologies can be adapted to different local and international contexts and scales.

Mathematical modelling of oil spill weathering processes for contingency planning in Izmit Bay

One of the main oil refineries in Turkey is located in Izmit. This results in a high volume of crude oil and oil products handled in Izmit ports. The region is consequently at a very high risk for oil pollution. Due to the destructive effects of oil on the various segments of the environment, comprehensive preventive measures for crisis management related to potential oil spill scenarios are necessary to minimize the contaminated areas. In this study, hydrodynamic data are obtained from the HYDROTAM3D, and 36 oil spill scenarios, which involve Basrah light, Iranian light, and Russian oil, are evaluated for oil spill weathering processes using ADIOS2. Although the API gravities of the three different oil types are within the same range, their weathering processes are noticeably different in terms of their viscosity and density. Moreover, Basrah light oil has a higher evaporation and viscosity increase rate compared to the other two types of oil. Of the three types of oil, the Basrah light is the most likely to hinder recovery actions. In situations of crisis management to provide efficient recovery actions, comparison of weathering modelling data for each handled oil type is necessary for oil spill contingency planning.

Performance of conventional drinking water treatment following dispersant remediation of an oil spill in surface water

Physical remediation such as the use of booms has been applied for most oil-spill cleanup activities in surface water. The application of dispersants has been controversial primarily due to the unknown impacts on drinking water sources. This study investigated changes in surface water quality following dispersant application to crude oil spills and the subsequent impact on the efficiency of ballasted flocculation, a physicochemical treatment process applied in many drinking water treatment plants (DWTP). Contamination of surface water was performed in the presence of crude oil concentrations (109 ± 13 mg/L) with and without dispersants. Water quality parameters such as turbidity and UVA254 were monitored and ballasted flocculation efficiency was assessed based on water quality as well as the removal of oil droplets, residual dispersant, and petroleum hydrocarbons as total organic carbon (TOC). Results showed that the measured water quality parameters except TOC are unsuitable indicators of petroleum hydrocarbon contamination in surface water. However, TOC lacked sensitivity when used in settled water to detect hydrocarbon contaminants. Although ballasted flocculation efficiency was not limited by the presence of crude oil and low dispersant concentrations when an optimized alum dose was applied (41 mg dry alum/L), the process was unable to remove other dispersant-related compounds that are not identifiable by the monitored water quality parameters. Measured concentrations of these compounds in settled waters were above the U.S. EPA's aquatic life benchmark (40 μg/L). Findings would be beneficial to DWTP in their efforts to upgrade their treatment processes and prepare oil-spill contingency plans.

Challenges Facing Myanmar in Developing a National Contingency Plan for Marine Pollution

ABSTRACT Myanmar became signatory to the OPRC 1990 in December 2016 and hence requires applicable vessels, ports and offshore facility operators to develop and maintain oil spill contingency plans coordinated with the National Contingency Plan. At about the same time, a super tanker terminal was constructed at Kyaukpyu deep-seaport on the west coast of Myanmar. This project made Myanmar an oil receiver country thus raising the risk of significant oil pollution incidents. To mitigate the risk, Myanmar developed its National Contingency Plan for Marine Pollution (NCP) in order to establish a coordinated oil spill preparedness and response policy and to align with the Regional Oil Spill Contingency Plan (ROSCP) developed under the ASEAN MOU for Joint Oil Spill Preparedness and Response (ASEAN, 2014). Even with the NCP, Myanmar is still encountering a number of challenges to be fully prepared for severe and disastrous pollution incidents. Chief among these is the establishment of a proper spill response capability including trained personnel and a stockpile of appropriate response equipment. Many options are being considered: government funding; establishing a mutual aid program led by industry; contract bases; or some combination of these. This paper looks at the actions Myanmar is taking to develop a state of the art NCP that is appropriate for Myanmar and the Region. The paper also discusses some of the key challenges Myanmar is facing, including transboundary issues and the solutions being considered and/or adopted to address such challenges.

Evolution of Contingency Planning in California – a Federal and State Coordinated Effort

ABSTRACT U.S. Coast Guard (USCG), U.S. Environmental Protection Agency (USEPA), and California Department of Fish and Wildlife (CDFW), Office of Spill Prevention and Response (OSPR) agreed to the joint preparation of oil spill contingency plans following the enactment of California and federal laws in 1990. With little guidance initially, six Area Committees embarked on a new process to create the first coastal Area Contingency Plans (ACPs) in 1992. In 2015, when emergency regulations to expand OSPR's jurisdiction statewide became effective, developing inland Geographic Response Plans (GRPs) became a top priority. Over the last 30 years, the ACPs have evolved into robust, nationally recognized planning documents, and response plans have expanded into inland environments. This paper will describe in detail the contributions and advancements in California oil spill contingency planning over 30 years. It will highlight OSPR's approaches for statewide consistency and coverage, interoperability between various state and federal plans, tools (including Geographic Information System (GIS) and various databases), improved sensitive site contacts and management, and lessons learned. It will also cover goals for future improvements in both marine and inland contingency plans.

The level of oil spill risk in Northwest Pacific and regional cooperation activities of NOWPAP MERRAC on marine pollution preparedness and response.

1. ABSTRACT The Northwest Pacific region, covering the four member states namely, People's Republic of China, Japan, Republic of Korea and Russian Federation, has been severely exposed to oil and HNS spills due to its high shipping density and high levels of industrial and economic growth and became a hotspot worldwide. Since member states are geographically close to each other, it is possible to cause transboundary issue affecting neighboring countries when oil and HNS spill incidents occur. In accordance with the need, the NOWPAP member states adopted the Regional oil and HNS spill Contingency Plan (RCP) in 2008, which provides the technical and operational framework for regional cooperation on major spill accidents, is a major achievements among the various regional cooperation activities. This was the first agenda actually adopted in the NOWPAP region and shows a national level of cooperation to protect the marine and coastal environment of the region. Particularly, to enhance the response capacities under the RCP, since 2006, member states jointly conduct oil and HNS spill response exercises (DELTA exercise) biannually, mobilizing actual response resources from the member states in a rotational basis. The 7th NOWPAP DELTA exercise was organized by Japan and Russia in Maizuru city, Japan (Oct. 2018). In addition to this, 19 communication exercises (BRAVO exercise) have also been implemented to test joint operational response procedures and associated communication tools in case of major spills. To further facilitate the exchange of information on marine pollution and preparedness in the region, MERRAC developed and operates the online pollution reporting system (POLREP) since 2015, which enables real-time exchange of information not only with the emails and fax but also through personal mobile phones of competent national authorities of member states. During the Sanchi spill incident (Jan 2018), the member states and MERRAC exchanged almost 300 notifications through POLREP concerning the location and trajectory of the spill and response operations. Furthermore, Member states exchange information on their national policies and response resources and has been building regional cooperation to strengthen its capabilities. In order to establish and maintain such regional cooperation system, MERRAC has been holding Focal Points meetings every year and Expert meetings every two years to exchange information on oil and HNS spill preparedness and response and implement Specific projects for various purposes by the national experts from the member states. In this presentation, we will review the oil and HNS risk levels in the NOWPAP region and examine the various cooperative activities and achievements and discuss the future prospects which MERRAC should go in through.

Kenya's National Framework to Enhance the Response Capability to Oil Spills

ABSTRACT Investment in the oil and gas sector in the East Africa region should commingle with the incorporation of best practices in oil spill emergency response. Upstream, Midstream, and Downstream operations must focus on prevention of emergencies but always be prepared to implement response actions if all engineering and safety defenses fail. Elements of environmental stewardship, applied scientific research, and technology are among key considerations needed in contingency planning to mitigate the socioeconomic and ecological consequences of hydrocarbon releases. Kenya is in the process of realizing its oil and gas potential. The country has started injection and production testing of its oil reserves in Turkana and has initiated oil export through the Port of Mombasa. These activities, coupled with increased rate of sea borne trade and planned relocation of Kipevu Oil Terminal to an offshore platform, places the country at risk of oil spills and therefore the need to have a robust system of spill prevention, preparedness and response. The World Bank's International Development Assistance (IDA) recognized the relevance of enhancing preparedness and response capability and, through the Kenya Ministry of Petroleum and Mining, initiated the development of the national framework for onshore and offshore oil prevention, preparedness, and response capacity in Kenya. The project is divided into four phases (Identification, Development, Implementation, and Kenya's Regional (East Africa) Response Capacity Enhancement) and four primary deliverables: National Oil Spill Contingency Plan for Marine and Navigable WatersOnshore National Oil Spill Contingency PlanNational Shoreline Cleanup Assessment Technique (SCAT) Guidance ManualNational Oiled Wildlife Response and Preparedness Guidance Manual This paper provides an overview of the four phases, describes the approach used to meet the project objectives, and provides an overview of the national oil spill contingency plans and national guidance manuals.

Geographic Response Plans: Preparing for Inland Oil Spills in California Waterways

ABSTRACT #1141189 Emergency regulations governing the development of oil spill contingency plans in California, along with financial responsibility for inland facilities, pipelines, refineries and railroads, became effective in 2015, with final regulations being adopted in January of 2019. With the California Department of Fish and Wildlife's (CDFW's) Office of Spill Prevention and Response's (OSPR's) authority for oil spill prevention, preparedness, and response being extended to inland waters of the State, the need to develop Geographic Response Plans (GRPs) for priority watersheds with higher risk of an oil spill became a top priority. Given the successful history with developing, implementing, and maintaining the California marine Area Contingency Plans (ACPs), OSPR has implemented a similarly effective GRP program. GRPs are driven primarily by access to sites along river systems and lakes where response activities are feasible. The process of developing GRPs for the State has consisted of: 1) developing a consistent document framework based on recently developed GRPs including the Region 10 Regional Response Team (RRT) and Northwest Area Committee (NWAC) GRPs in the Pacific Northwest, the Feather River GRP developed by Union Pacific Railroad in California, as well as previously developed GRPs by the United States Environmental Protection Agency (USEPA) Region 9 (California, Nevada, Arizona); 2) implementing a Statewide GRP Steering Committee (SGSC) consisting of State, federal and local agencies, industry, oil spill response organizations (OSROs), an environmental Non-Governmental Organization (NGO), and a tribal representative; and 3) developing partnerships with industry representatives, and federal, State and local agencies, including first responders [Local Emergency Planning Committees (LEPCs) and others] to ensure critical local expertise and information is incorporated in each, individual GRP. With the emerging trend of oil by rail transportation; historical spill threats from pipelines, fixed facilities, and truck transportation; and the promulgation of emergency regulations extending OSPR's oil spill preparedness activities to inland waters, the development of GRPs for at-risk watersheds became critical.

The Problematic of Disaster Management Law and Policy in Nigeria: A Study of Bayelsa State

The study examined the problem of disaster management in Nigeria using Bayelsa State as a case study. Four null hypotheses were raised and tested at a 0.05 level of significance. The study adopted the descriptive survey design and sample sizes of 300 adults were drawn from fifteen (15) affected communities in Bayelsa State. The instrument used for data collection was a disaster management questionnaire and the data were analyzed using chi-square. The finding of the study revealed that there is a significant relationship between poor integrated policy and action plan as well as weak institutional capacity and collaboration of disaster management agencies and effectiveness of disaster management in Bayelsa State. The study clearly showed that there is a significant relationship between poor commitment and piece-meal approach by the multi-layered levels of government as well as poor stakeholders’ participation and synergy and effectiveness of disaster management in Bayelsa State. The study recommended among others that long-term monitoring and surveillance mechanism; continuous provision of infrastructure for the host communities by prospecting oil companies; adequate funding by governmental and non-governmental and the development of a national oil spill contingency plan should be adopted and deployed with an eye to guaranteeing sustainable development of the environment in the region.

Oil spill contingency plan (OSCP) by environmental sensitivity index (ESI) analysis at East Barito District, South Barito District and Kapuas District (Tamiang Layang, Buntok and surrounding area), Central Kalimantan Province

The central Kalimantan has envolved into a new oil and gas industry area where potential impact on environmental need to be anticipated comprehensively for environmental protection from oil spill. The locations are East Barito District, South Barito District and Kapuas District (Tamiang Layang, Buntok and surrounding area), Central Kalimantan Province. The main problem of this study is determining areas of sensitive and vulnerability to oil spill. The aims of study were to identify the factors and components that affect the level of ESI to oil spill and analyse and establish environmental sensitivity rank for oil spill contingency plan. The methodology of study carried out by identifying and assessing each landuse unit and analyse performed by GIS method with ESI formula. Interpretation and classification of landuse used Landsat TM imagery that acquired in 2014 and updated in 2018 and field survey in October 2014. The result of analysis showed environmental sensitivity index divided into four categories, dominated by high sensitive (40,8%) due to the presence of protected and conservation forest, less sensitive (31,9%), moderately sensitive (14,6%), and insensitive (12,8%). General condition of study area is lowland and swamp area and potential to flood. The environmental protection from oil spill should be mitigated and prioritized for sustainable development.

Enhancing Oil Spill Response Capacities in the South Baltic Sea Region via Cross-Border Utilization of Biodegradable Oil Binders

Occurrences of oil spills are responsible for very significant environmental degradation; they are more likely to happen in areas with dense shipping traffic, or in close vicinity of transport pipelines and/or other infrastructures used for production and processing purposes. Without international cooperation, individual countries often lack sufficient resources and assets to successfully respond to large-scale oil spill incidents. This can be related to the vast quantities of oil involved in those incidents or the lack of necessary special equipment for dealing with the tasks at hand by the country under the need to respond. For successful resolution of oil spill incidents, close and effective international cooperation -especially between neighboring countries that usually “share the burden” of oil pollution- is a vital necessity. On this basis, the South Baltic Oil (SBOIL) project aims to strengthen the existing oil spill response capacities in the South Baltic region, introducing a cross-border spill response tool based on the new ‘green technology’ of biodegradable oil binders (BioBinders).
 In order for this new concept to be implemented, it is necessary to examine the international and national regulations and guidelines with reference to sorbent use and exchange of oil spill equipment in the area of interest and also analyze the national oil spill contingency plans of the different countries involved in the project. After investigating the legal requirements for the utilization of BioBinders in the South Baltic region, the analysis at hand presents the outcomes of a Table Top Exercise that was based on a realistic oil spill scenario in the wider region. This Exercise tested the compatibility of International/National/Regional plans regarding the use of the BioBinders and examined the topics of recovery and waste management, including alternative techniques available for oil spill response. Results point towards the direction that the use of the BioBinders is promising and represents a response option to improve the existing oil spill response capacities in the South Baltic region; the main challenge lies with the difficulty in dealing with waste management, mainly because of the current legislation in place within the participating countries.

OIL SPILL RESPONSE PREPAREDNESS MODEL THROUGH COMMUNITY PARTICIPATION IN TELUK PENYU BEACH, CILACAP REGENCY

In Indonesia, oil spill incidents often occur; thus, it has become a matter of national concern. Cilacap Regency is one of the regions in Indonesia that is prone to oil spills, with a history of frequent oil spill incidents during 2000–2018. Oil spill response preparedness needs the integrated effort between government and communities to minimize the environmental impacts of oil spills. A problem usually encountered is the lack of integration of community participation in the oil spill contingency plan because of the limited knowledge of the community regarding oil spill response preparedness. This study aimed to build an oil spill response preparedness model through community participation in Teluk Penyu Beach, Cilacap Regency. This study used the system dynamics modeling method. Results showed that the oil spill volumes in the waters (decay behavior) and on the beach (goalseeking behavior) rapidly decreased after 240 h (10 days). In conclusion, oil spill response preparedness needs the integration between company and community participation by increasing knowledge through community involvement in a combination of oil spill response exercises.

A new stochastic oil spill risk assessment model for Persian Gulf: Development, application and evaluation

Persian Gulf is a semi-enclosed highly saline reverse estuary that is exposed to the risk of oil spills in offshore oil and gas activities. In the early 2000s, a specific version of NOAA's Trajectory Analysis Planner (TAP II) was developed for Persian Gulf to assist regional organizations in preparing oil spill contingency plans. In this research, a new stochastic model is developed to cover the limitations of TAP II. The new model is based on an advanced trajectory model, which is now linked with high resolution spatiotemporal data of the wind and sea current. In a case study, the developed model is compared with TAP II, and evaluated by multiple tests designed for analysis of uncertainty, sensitivity, reliability and variability. The case study proved the applicability of the new model, and the evaluation tests provided useful information for the future development of the model.

Environmental Sensitivity Index Mapping: A Case Study of PPMC Pipeline along Ugbomro Community and Environ, Delta State, Nigeria

Environmental Sensitivity Index (ESI) mapping provide a concise summary of coastal/inland resources that are at risk if an oil spill occurs nearby. Environmental sensitivity index (ESI) maps can be used for oil spill contingency planning, environment management planning and emergency response. To this end, the study attempts to establish the inland habitats and their sensitivity to oil spill along the 4.95km of the pipeline passing through Ugbomro community and as it relates to its environs. Ikonos image of the area obtained from Google Earth, were digitized manually and the land use/land cover map of the areas were derived using ArcGIS 10.1. The ESI classification and ranking was done for the inland habitat by considering the importance of indigenous flora/fauna species to rural livelihood, oil ecosystem interaction, and ease of clean up. The result suggests that built up area, water body and wetland having ESI ranking to be Very High and ESI classification of 5A, 5B and 5C respectively. Farmland ESI ranks High with ESI classification of 4, Semi natural vegetation has ESI ranking of Medium with ESI classification of 2 and bare surfaces had ESI ranking to be Low and ESI classified as 1. An emergency response zone and priority booming were proposed along the pipeline route as a means of curtailing the spread of oils to sensitive resources.

Assessing the feasibility of marine oil spill contingency plans from an information perspective

This paper evaluates the feasibility of marine oil spill contingency plans (OSCPs) systematically from the perspective of information availability and accuracy. A conceptual model integrating the fundamental elements of contingency plans is introduced, and the relevant information flows for marine oil spill emergency response processes are identified. The Dempster–Shafer (D-S) reasoning approach was adopted to develop a series of models for assessing the information-related feasibility of contingency plans. The models were validated through a case study, which proved that simplifying information requirements and improving the availability and accuracy of key information are effective methods of improving the information-related feasibility of contingency plans. Such research issues as improving the availability and accuracy of information and obtaining experts’ subjective opinions require further investigation. The main contributions of this study are identifying the importance of information for implementing OSCPs and developing a well-structured analysis framework and an appropriate method for assessing the information-related feasibility of OSCPs.
