This is guidance for managing water from containment sumps and spill basins. Also included are options for safely and legally managing absorbents from cleaning up spills of petroleum (gasoline, diesel or kerosene). This guidance does not pertain to managing petroleum impacted debris and media generated from a tank closure or cleanup or to used oil cleanups. For information on managing wastes from the inside of petroleum storage tanks, see Management of Petroleum Storage Tank Wastes (PUB 2040). For information on fuel filter management and additional details, see Managing Gasoline Dispenser Fuel Filters and Waste Associated With the Operation of Fuel Dispensing Systems (PUB 2364).

Options for disposing of water from routine maintenance (containment sumps, spill basins)

For recovered fuel management options, see section 1 in Management of Petroleum Storage Tank Wastes (PUB 2040)

Disposal of used petroleum impacted absorbent pads, booms or dry spill (kitty litter)

What contractors should know

Contractors servicing tank sites may bring petroleum impacted absorbents generated in the course of performing their duties at those sites back to the contractor’s facility for proper hazardous waste characterization, management and disposal. However, when doing so, the contractor shares responsibility with the owner/operator of the tank site for complying with laws and regulations regarding that waste. Though not required by regulation, it is a good management practice for the contractor to have a written agreement with the tank site owner/operator specifying how and where each of the materials they accepted from the site will be recycled, managed, shipped and disposed. For more information see the fact sheets referenced above. 

Contractors may also transport sump test water suitable for use from one gas station to another. When no longer suitable for use, the contractor may bring the test water back to his or her facility for proper management according to options above.

This guidance document does not detail how to store, label, transport or dispose of soil and water from tank cleanouts, closures and remediation.
