BSoil and groundwater contamination from leaking petroleum products or chemicalsCorrect

CProperty tax avoidance schemes in which owners claim contamination has eliminated all value, reducing their assessed value to zero and eliminating tax liability

DFire hazards from above-grade petroleum vapors that collect in enclosed spaces when underground storage tanks release product to the surface through pressure venting
