IN ADDITION TO EXTENSIVE TESTING BY AN INDEPENDENT LABORATORY TO DETERMINE APPROVED SOURCES OF SUPPLY, SEC PERFORMS ACCEPTANCE TESTS ON EACH SHIPMENT OF OIL RECEIVED.

SEC RECEIVES ITS OIL IN DEDICATED TANK CARS AND TRUCKS, AFTER WHICH SAMPLES ARE TAKEN FROM THE BOTTOM, MIDDLE AND TOP OF THE TANK CARS BEFORE PLACING THE OIL IN BULK STORAGE TANKS. THE OIL IS THEN DEGASIFIED AND STORED. SEC FILTERS OIL AGAIN AT EACH POINT OF USE THROUGHOUT THE PLANT.
