Are marinas and airports included under the definition of "retail gas station?"

Gas stations in marinas and airports that sell fuel for boats and airplanes are not included within the definition of "retail gas station" for purposes of higher reporting thresholds EPCRA §§311/312.  In the February 11, 1999, Federal Register, EPA added the phrase "for motor vehicle use on land" to the definition of "retail gas station" to clarify their intent (64 FR 7031,7035)
