Corralled in Corvallis

Corralled in Corvallis Here is the case study you will write about: Here’s the situation. Your client is selling her commercial property in Corvallis OR (~44 degree 36’ 36.60” N; 123 degree 09’ 30.51” W). The adjacent vineyard owner is interested in buying, but is aware that there is an underground storage tank on the property and wants any liability issues clarified and the tank removed. In a review of the client’s records, an inventory analysis suggests that as much as 12,000 gallons of gasoline or other stored liquid may have leaked from the 15,000 gallon tank over the previous 25 years of use. Your boss assigns you the task of working up a preliminary analysis of the situation so that a scope and budget estimate can be presented to the client. Furthermore, it is clear that if you do a good job on this, you can be expected to be the Project Manager and potentially be recognized for a promotion, maybe a raise (or better yet, get a good grade). Evaluate the situation from both a state and federal regulatory perspective. Using any four of the following compounds MTBE, 3-ethyltoluene, isooctane, cyclohexane, naphthalene, TCE, carbon tetrachloride, or dimethylethyl benzene as surrogates for the tank contents (assume each of your four compounds were 0.5%, 2.1%, 0.32%, and 2.7% of total tank volume, in whatever order you choose), and any available information on local soil, groundwater, precipitation, etc., determine the likely fate/location/distribution of the gasoline in the subsurface. Neglect any volatilization to the atmosphere. In other words, do a mass balance for those four compounds. Make sure to include a summary table amount of each compound initially, what phases (air, liquid, solid) and concentrations for each compound, relevant chemical info for each compound, and other information. Summarize the federal and state UST regulations related to cleanup and note any differences between them.
