The containment area does not have cracks or gaps to allow the <br />escape of spilled material. The containment area is coated witli an epoxy which is re- <br />applied annually, and is equipped with a level indicator for leak detection which will <br />sound an alarm when liquid is detected. Liquid is recycled using an AODD pump_ <br />Site Security: The entire site is fenced. The gate is locked when company personnel are <br />not present. <br />Secondary Containment findings: The secondary containment system is of sufficient <br />capacity and condition for the containment of releases from the 370 gallon neutralizer <br />tanks and ancillary equipment.
