11 Miss. Code. R. § 5-2-280.4-8.2 - Dispenser Islands and Piping
Samples must be analyzed for the products last transferred in the piping. However, if evidence of a leak from a previously stored product is found or it is known that the piping transferred a different substance at one time, the samples must be analyzed for that substance also.
In addition, if both diesel fuel and gasoline piping are in the same trench/dispenser island, all samples collected from the piping trench/dispenser island must be analyzed for both BTEX and PAH.
