Unit III Case Study: You Have Been Hired As A Consultant

Unit III Case Studyyou Have Been Hired As A Consultant By Your Towns

You have been hired as a consultant by your town’s emergency management coordinator to help develop emergency action plans. One of the reasons you were selected is your expertise in using the General Behavior Model (GEBMO) to assess risks. Your first task is to assess the hazardous material risks at a local gas station. The station has one 30,000-gallon underground storage tank compartmentalized to hold 10,000 gallons each of the three gasoline grades, and there is one additional 10,000-gallon tank for diesel fuel. The station has four pumps, and each one can deliver all four products.

Also on site is a 2,500 sq. ft. concrete block building used for the cashier and retail sales of service station and convenience store items. The station is located at a busy intersection near the center of town. It is adjacent to several other local businesses that do a brisk business during the day. Across the street from the station is a large housing development with an elementary school. Behind the station is a city park with playgrounds, baseball fields, and a large wooded area.

Use the GEBMO framework to assess the risks related to the fuels in the underground tanks. Consider physical, chemical, and natural hazards that may contribute to the risks. 1. Discuss how you applied each of the steps in the GEBMO process and what risks you identified. 2. Provide recommendations for preventing spills or releases. 3. Discuss response actions required in the event of a spill or release. Support your discussion with appropriate references and in-text citations. Your submission must be a minimum of two pages and a maximum of four pages in length.

Paper For Above instruction

The application of the General Behavior Model (GEBMO) to assess risks at the local gas station involves systematic consideration of hazards, vulnerabilities, and potential consequences related to hazardous materials. This model facilitates a comprehensive understanding of risks, especially in an environment with multiple fuel tanks and nearby sensitive areas. This paper discusses the step-by-step application of GEBMO, identifies hazards, and offers prevention and response strategies grounded in current best practices and literature.

Application of GEBMO Steps and Risk Identification

The GEBMO process begins with hazard identification, focusing on the physical properties, chemical characteristics, and natural vulnerabilities associated with the underground fuel tanks. The first step involves analyzing the fuels stored—gasoline and diesel—which are both highly flammable, volatile, and prone to vapor expansion under certain conditions (Nordin et al., 2020). Gasoline's high volatility heightens the risk of vapor cloud formation, especially in the confined underground tanks, increasing the potential for explosion or fire in the event of a leak (Zhou et al., 2021). Diesel, while less volatile, still poses a fire risk if it leaks and comes into contact with ignition sources.

The subsequent step involves assessing the vulnerabilities of the containment system and surrounding environment. The underground tanks’ compartmentalization to hold multiple grades necessitates rigorous monitoring, as leaks in one compartment can easily contaminate surrounding soil and groundwater (EPA, 2022). The proximity to residential neighborhoods, a school, and a park amplifies the risks, where accidental spills could endanger human health and the environment. Natural hazards such as flooding or seismic activity could compromise tank integrity, increasing spill potential (Cinar et al., 2018). Physical hazards include corrosion of aging tanks, which can lead to structural failure (ASTM, 2019).

Risks Identified

The critical risks from the GEBMO assessment include chemical spills resulting in soil and groundwater contamination, vapor explosion hazards during leaks, and fire risks due to the flammable nature of the fuels. Environmental risks are accentuated by the station's placement near residential areas, schools, and recreational spaces, where exposure to toxic vapors or contaminated groundwater could impact public health. Additionally, natural hazards such as floods could exacerbate these risks by facilitating fuel migration beyond containment zones, leading to broader environmental contamination (Choi et al., 2020).

Recommendations for Preventing Spills and Releases

Preventive measures should prioritize tank integrity and leak detection. Regular inspections and maintenance, including corrosion control, are essential to prevent tank failures (API, 2017). Implementation of secondary containment systems, such as double-walled tanks and sumps, can prevent environmental contamination. Upgrading leak detection systems with sensors that monitor vapor and liquid leaks provides early warning signs allowing prompt action (EPA, 2022). Staff training on handling and storage procedures improves operational safety, reducing human error that can lead to spills.

Furthermore, installing automatic shutoff valves triggered by leak sensors can swiftly contain leaks. Managing the surrounding landscape, such as elevating tanks above flood levels and constructing berms, can mitigate natural hazard impacts (Cinar et al., 2018). Community engagement and clear signage inform local residents about safety procedures, creating a proactive safety culture.

Response Actions for Spills or Releases

In the event of a spill or release, an immediate response plan should be activated. The first step involves evacuating the nearby vicinity and contacting emergency services, including hazardous materials (HazMat) teams, to contain and neutralize the spill (NRC, 2019). Containment efforts should focus on controlling surface spills with absorbent booms and pads, preventing fuel migration into soil and water. Ventilation systems should be employed to disperse vapors safely, minimizing explosion risks (OSHA, 2020).

Post-incident, environmental sampling and monitoring are crucial to evaluate contamination extent. Remediation may involve soil excavation, groundwater treatment, and tank repairs (EPA, 2022). Additionally, investigating the cause of the spill allows for improvements in safety measures to prevent recurrence. Communication with local residents is vital to reduce panic and provide clear guidance on safety precautions.

Conclusion

The use of GEBMO provides a structured approach for identifying and mitigating risks associated with underground fuel storage at the gas station. Emphasizing preventive maintenance, early detection, and rapid response capabilities can significantly reduce environmental and public health hazards. Continuous review and testing of emergency plans ensure readiness for potential incidents, safeguarding the community and environment effectively.
