What is Environmental Risk Assessment

A systematic and well documented process to define and quantify potential human and ecological risks from exposure to oil and gas products released from a proposed project alone and in combination with other past, present, and future projects in a region

What is Risk Assessment?

a process that determines the nature and magnitude of a threat by analyzing

potential hazards and evaluating existing conditions of vulnerability that could pose

a potential threat or harm to people, property, livelihoods and the environment

The Local Oil and Gas Retail Outlets – the facts

• There over 8000 petrol and LPG filling stations• Retail PMS, LPG, Kerosene, Diesel, Lubricants, etc• Potential sources pollution in the environment• Environmental Performance of oil and gas retail outlets is regulated by DPR• EIA regime is strong, post EIA monitoring is weak• Risk management could be integrated into EIA and Post EIA monitoring (Environmental Audits)• Risk Interaction matrix would assist EIA review and simplify decision in DPR

Risk Analysis - Methodology

• Brainstorming• Checklist• Hazards Identification (HazID)• Operational Hazards (HazOP) • Failure Mode and Effect Analysis (FMEA)• Human Error Analysis (HEA)• Technique of Operations Review (TOR)

The Risk Interaction Matrix

The Computations

GENERAL RISK ASSESSMENT QUOTIENT

RR = Risk Rating (100)

AVRR = Summation of Risk Rates ÷ N

Where;

AVRR = Average Risk Rate N = Total number of risks triggerse.g.AVRR = 544 ÷ 39 = 13.95 (falls within 1 – 24) hence is an

acceptable risk

Probability (Pr) Severity (S) Risk Rating (100)

1- Rare(uncommon)

1 - No injury - Insignificant (have no effect)

No risk 0

2 - Unlikely (infrequent)

2 - Minor injury (little effect, first aid?)

Acceptable 1 - 24

3 - possible ( Feasible but not common)

3 - Significant (may pose a problem, hospitalisation?)

Moderate risks (tolerate?) 25 - 50

4 - Likely (has before, will again)

4 - Major (Will pose a problem, disability?)

High risks 51 – 75

5 - Certain (occurs frequently)

5 - Critical(Immediate action required, deathly?)

Dangerous 76 - 100

The Legend

Risk Assessment in EIA – strategy for DPR

• Expand the scope of ERA in the next EGASPIN• Develop and adopt a standard risk assessment technique• Communicate standard to stake holders• Incorporate standard ERA into EIA and Environmental Audits of oil and gas retail outlets• Integrate standard in review and decision making• Review standard every decade (with EGASPIN?)

Conclusions and Recommendations

• ERA and EIA share the same objectives - sustainability• A local ERA standard for oil and gas retail outlets will enhance their sustainability• A standard ERA is strongly recommended for EIA and Environmental audits of all oil and gas retail outlets
