BEST PRACTICES

Although not all the practices listed below are required by regulation, they include best practices that should be implemented in the management of storage tanks.

• Tanks should be assigned to personnel or departments that are accountable for tank condition, material and maintenance.
• Inventory and assess the condition, use and need for storage tanks. For tanks that are not needed remove or decommission tanks in accordance with local regulatory requirements.
• Older tanks should be removed and replaced if needed, with equipment that meets current regulatory requirements. Guidance note PPG27: Installation, decommissioning and removal of underground storage tanks details regulations and best practice.
• Underground tanks should have secondary containment.
• Tanks should have a leak detection system. Be sure your leak detection system is "certified" for the type of tank, size and material. This system should be checked at least every 30 days.
• Spill buckets should be installed at fill points to contain drips and spills that may occur during delivery. Keep spill buckets clean and free of liquid and debris.
• Tanks should have overfill protection systems installed that may include automatic shutoff devices, overfill alarms or ball float valves. Be sure the delivery person knows what type of overfill protection your tank has.
• Be sure you order the correct amount of product for delivery. Order only the amount of product that will fill the tank to 90% of capacity. Be sure to account for product already in the tank.
• Monitor product delivery to ensure overfilling or spills do not occur.
• Be prepared to respond to releases. Be sure all personnel involved with tank operation and maintenance are familiar with the SPCC plan.
• Perform practice drills.
• If a spill or release occurs:
• Take action as soon as possible that does not endanger personnel to prevent release of additional product.
• Turn power off to the dispenser. For flammable or combustible material keep ignition sources away from the release area.
• Report releases or suspected releases to local regulatory agencies in accordance with local regulations.
• Maintain records of :
• Inventory control.
• Release detection inspections.
• Maintenance activities.
• Spills and releases and responses.
