Refinery letter states that "final calculations confirm that no reportable quantities were exceeded." The fresh and spent acid tanks were equalized to reduce the pressure in the fresh acid tank L-431 to slow the leak rate. Bolts on the leaking flange was replaced, however that did not stop the leak.
