Which stated history most directly signals potential petroleum contamination needing environmental due diligence?
Correct Answer
A) Former fuel dispensing with underground storage tanks
Former fuel-storage or dispensing use can indicate potential petroleum contamination requiring appropriate environmental due diligence by qualified professionals. A Phase I may be appropriate depending on the transaction and assignment. Neither new construction nor residential labeling proves an uncontaminated site.
Why This Is the Correct Answer
Option A is correct because former fuel dispensing with underground storage tanks can indicate potential petroleum contamination. That history calls for appropriate environmental due diligence by qualified professionals. Depending on the transaction and assignment, a Phase I environmental site assessment may be appropriate.
Why the Other Options Are Wrong
Option B: A new subdivision on former farmland with no history provided
Option B, a new subdivision on former farmland with no history provided, states no use linked to petroleum storage. Without stated history, it does not directly signal petroleum contamination, though it also does not prove the site is clean.
Option C: A recent house with no history provided
Option C, a recent house with no history provided, gives no information about fuel storage or dispensing. New construction does not prove an uncontaminated site, but nothing here directly signals petroleum contamination.
Option D: An office label with no history provided
Option D, an office label with no history provided, offers only a use label. It does not directly signal petroleum contamination the way a former fuel dispensing use does.
Old pumps, buried tanks
Where fuel was pumped, tanks may lie buried and may have leaked. That history is the signal to investigate.
How to use: Use this when a question asks which site history signals possible petroleum contamination.
Exam Tip
Pick the option with a specific history linked to the contaminant in question. Options with no history are weaker answers, but they do not prove a site is clean.
Common Mistakes to Avoid
- -Assuming new construction proves a site is uncontaminated
- -Treating the appraiser as qualified to confirm or rule out contamination
Concept Deep Dive
Analysis
This question tests recognition of a site history that points to possible petroleum contamination. Former fuel dispensing with underground storage tanks is a direct indicator. The other options give no history, and missing information is not the same as a warning sign or a clean bill of health.
Background Knowledge
Environmental concerns such as underground storage tanks can affect value, financing and marketability. Appraisers are not environmental experts, so they note observed or known conditions and rely on qualified professionals for assessment. Prior uses such as gas stations, dry cleaners and industrial operations are common contamination indicators.
Real-World Application
An appraiser learns that a vacant lot was a gas station decades ago. She discloses the history, notes that she is not qualified to assess contamination, and recommends an environmental assessment by a qualified professional.
