Our practice is for each tank to be a batch and we test that tank once even though it may be used to supply several distribution systems. If several tanks are required to make up a pipeline tender, each tank is tested separately and the separate certificates of analysis provided to the pipeline. Will this practice still be acceptable?
Yes. Moreover, EPA believes that each separate tank of produced gasoline must be a separate batch, and that gasoline produced and contained in more than one tank may not be treated as a single batch. (7/1/94)
