The containment area does not have cracks or gaps to allow the <br />escape of spilled material. Arm 1 (East encs) is connected to area 2 by an open 6 in. pipe, and area 2 is <br />connected to area 3 (West end) by a 6 in- pipe. These pipes will accommodate flow of 300 to 500 gpm <br />depending upon the bead. Area 1 is equipped with a level indicator for leak detection, which will sound an <br />alarm when liquid is detected. Liquid is recycled using an AODD pump_ <br />Areas 1, 2 & 3 are coated with epoxy which is re-applied annually. <br />Secondary Containment Leak Tests — The pre -neutralizer area (Ards 1, 2 6. 3). and the final neutralizer area, <br />are filtcxl with water (area 3 partially filled, area 1 -- remove pumps before fil ling), and visually checked for <br />leaks. Upon completion, the water is treated in the system and discharged to the sewer. Testing Will be in Mated <br />this year or eardy next and repeated every five years.
