An analysis of exxon valdez oil spill

However, the twinning project would actually triple pipeline capacity because the new inch line would have more than double the volume of the existing inch line. The above figure depicts the fact that as the exactness of a statistical model increases, the level of improvements in decision-making increases.

Based on our findings so far, we question whether there would be significant enough benefits for British Columbians to offset the risks. Trans Mountain and the Alberta oil sands Building the Trans Mountain pipeline will only make economic sense if the oil sands undergo significant expansion.

The sender make common what is private, does the informing, the communicating. Modern reformulated and oxygenated gasolines must now meet stricter physical and chemical specifications.

Toestimate the biological danger of oil after a spill, knowledge of the harmful effects of the components is necessary. Recent cuts to the Coast Guard will have an impact on the ability to respond to spills in a timely and efficient fashion, as the number of regional offices is reduced from five to threeand the Kitsilano and Vancouver stations are closed.

After 20 years, there is no evidence suggesting that either cleanup workers or the residents of the communities affected by the Valdez spill have had any adverse health effects as a result of the spill or its cleanup. Environmental forensic investigations typically address questions aimed at identifying the nature of contamination, its sources, and the timing of its release to determine the responsible parties.

The sequence from data to knowledge is: The situation is even complicated by the fact that biochemical reactions rarely proceed by a single pathway.

However, do we need emotions in order to be able to judge whether a decision and its concomitant risks are morally acceptable.

Root Cause Analysis

This technology may involve nutrient enrichment in the form of fertilizer application or further manipulation of site conditions such as inoculations with selected or adopted microbial population, mixing and aeration of the soil surface, pH adjustment and irrigation. The reaction time for solidification of oil is controlled by the surface area or size of the polymer or dry pellets as well as the viscosity and thickness of the oil layer.

Toxic components in oil may exert their effects on man through inhibition of protein synthesis, nerve synapse function, and disruption in membrane transport system and damage to plasma membrane Prescott, et al.

Those few NAPLs containing more than ppm total sulfur were likely from an area of the site where pre diesel fuels were stored in underground storage tanks by the earlier operator.

Assessing the risks of Kinder Morgan’s proposed new Trans Mountain pipeline

Apart from using adapted organisms, genetically engineered microorganisms are in use. These events or soil characteristics reduce or increase the bioavailability of petroleum hydrocarbons, the inherent toxicity and hence biodegradability.


A study of marshlands affected by a oil spill in West Falmouth, Massachusetts discovered similar concentrations of soil contamination 30 years later.

Even when they know the statistics; they are more likely to rely on personal experience than information about probabilities. As crude oil creates anaerobic condition in the soil, coupled to water logging and acidic metabolites, the result is high accumulation of aluminum and manganese ions, which are toxic to plant growth.

With a bioreactor, temperature, pH and other parameters are optimized for degradation. Animals can be poisoned, and may die from oil entering the lungs or liver.

Wisdom comes with age and experience. Decision-makers often face a severe lack of information. What kind of jobs will they be? Then, when they finally decide, they neglect to consider all the implications of their decision. One may ask, "What is the use of decision analysis techniques without the best available information delivered by Knowledge Management?

What is diluted bitumen? This question has direct practical implications: See Stout et al. Knowledge is more than knowing something technical. Left out, the surface crusts over but the inside still has the consistency of mayonnaise — or mousse.

Some specific bioremediation processes that may require engineering are summarized below. Collaborating with InnoCentive they found a partial solution for the flow of oil. During the review process, Kinder Morgan will be required to set out a detailed pipeline route. Lacks a reliable system to track the number, size or environmental impacts of spills.

One of the greatest challenges to humanity today is the endangering of biota as a result of environmental pollution from crudeoil.What is diluted bitumen?

Bitumen has very different properties than conventional is a heavy and viscous oil that occurs mixed with sand, clay and water and is found underneath Canada’s boreal forest. Apr 26,  · What is the safest way to move crude oil around the country?

Short answer: truck worse than train worse than pipeline worse than boat. But that’s only for human death and property destruction. Explanation of other related emergency planning laws. Other federal environmental laws require facility emergency plans that may not be easy to access or review.

Decision making under risk is presented in the context of decision analysis using different decision criteria for public and private decisions based on decision criteria, type, and quality of available information together with risk assessment.
