Material Loss Prevention

Loss prevention programs are designed to reduce the chances of spilling a product. A hazardous material becomes an RCRA hazardous waste when it is spilled. A long-term, slow-release spill is often hard to find, and can create a large amount of hazardous waste. A material loss prevention program may include the following directives:

• Use properly designed tanks and vessels for their intended purpose only

• Maintain physical integrity of all tanks and vessels

• Install overflow alarms for all tanks and vessels

• Set up written procedures for all loading, unloading, and transfer operations

• Install sufficient secondary containment areas

• Forbid operators to bypass interlocks or alarms, or to alter setpoints without authorization

• Isolate equipment or process lines that are leaking or out of service

• Install interlock devices to stop flow to leaking sections

• Use bellow seal valves and a proper valve layout

• Document all spillage

• Perform overall material balances and estimate the quantity and dollar value of all losses

• Install leak detection systems for underground storage tanks in accordance to RCRA Subtitle I

• Use floating-roof tanks for VOC control

• Use conservation vents on fixed-roof tanks

• Use vapor recovery systems (Metcalf 1989)
