Summary of Best Management Practices
• All employees who work in the processing area or handle material transfers are trained in the operation and maintenance of
equipment to prevent discharges. Training includes a discussion of the transfer and deliver/acceptance procedures, and
applicable laws, rules and regulations. This training is provided by a knowledgeable person with experience in spill response,
containment and control. Training is conducted at least once per year for these personnel.
• Facility tanks, containment and related piping are inspected periodically.
• The rail car loading/ unloading area has a single connection point for loading/unloading operations, which precludes the
opportunity for confusion in piping. The connection is capped when transfer operations are not in progress. The rail car
loading/unloading area services the tank farm, and these tanks are equipped with local audible high level alarms. The rail
loading/unloading area is designed with a secondary containment system to prevent leaks and drips from the rail cars from
entering the environment.
• All outdoor storage tanks have secondary containment.
• An outdoor raw material / chemical storage area has secondary containment and a sump.
• The facility has a Tank Integrity Program to address inspections and any necessary repairs.
• Security personnel are onsite 24 hours/day, 365 days/ year.
• All pump control circuits are not powered during non -operational hours.
• Spills that occur outside of secondary containment areas are cleaned as soon as possible.
• Granular absorbents are kept around the facility to respond to spills.
