All maintenance records must be maintained for 5 years. It is recommended that the building supervisor retain a copy also. In the event a loss of inventory is discovered, notify EHO immediately. All losses must be investigated and the cause determined within 48 hours. Most spills and releases occur during the filling process.
Careful supervision is the best way to prevent overspills.
Several regulations exist to help in the prevention of overspills as well. The level gauge must be accessible to the product carrier. It also must be situated so it is easy to read. All ASTs must be equipped with a check valve and all fill ports must be color coded. A list of the color codes can be found in Appendix B. ASTs must also have secondary containment in place to protect the environment in the case of an accidental overspill.
