GENERAL
• Utilize diking and other forms of containment and diversions around tanks, drums, chemicals, liquids, pits, impoundments, or well pads
• Use drip pans, sumps, or liners where appropriate
• Limit the amount of land disturbed during construction of pad, access road, and facilities
• Employ spill response plan (SPCC) for all facilities
• Dispose properly offsite any wastes fluids and other materials
MATERIAL HANDLING, ACTIVITIES, PRACTICES AND STORM WATER DIVERSION
• Secondary containment of tanks, drums, and storage areas is mandatory to prohibit discharges to surface waters. A minimum of 110% capacity required of largest storage tank within a containment area
• Material handling and spill prevention procedures and practices will be followed to help prohibit discharges to surface waters
• Proper loading, and transportation procedures to be followed for all materials to and from locations
EROSION CONTROL
• Pad and access road to be designed to minimize erosion
• Pad and access road to implement appropriate erosion control devices where necessary to minimize erosion
• Routine inspections of sites and controls to be implemented with additions, repairs, and optimization to occur as necessary to minimize erosion
SELF INSPECTION, MAINTENANCE, AND HOUSEKEEPING
• All employees are trained in spill response, good housekeeping, material management practices, and procedures for equipment and container washing annually
• Conduct internal storm water inspections per applicable stormwater regulations
• Conduct routine informal inspections of all tanks and storage facilities at least weekly
• All containment areas are to be inspected weekly or following a heavy rain event.
• Any excessive precipitation accumulation within containment should be removed as appropriate and disposed of properly
• All structural berms, dikes, and containment will be inspected periodically to ensure they are operating correctly
SPILL RESPONSE
• Spill response procedures as per the BBC field SPCC Plan
VEHICLE & LOCATION PROCEDURES
• Vehicles entering location are to be free of chemical, oil, mud, weeds, trash, and debris
• Location to be treated to kill weeds and bladed when necessary
