Enterprise Transportation Company

Year Submitted: 2005

Process: Chemical Storage and Delivery

Industry: Chemical Storage and Distribution

Wastes Reduced: First Flush Wash Water

Location: Baytown TX

No. of employees: 140

Contact: Karen Saucier

Phone: 409/842-5650



Description:

The company transported chemicals for delivery in 7000 gallon trailers. The trailers returned to the facility containing various amounts of chemical residuals (heel). The Resource Recovery and Conservation Act (RCRA) requires that residual materials may not exceed 3% of the total capacity for a vessel to be considered “RCRA empty”. Any amount over that must be contained and disposed of as hazardous waste. Often the trailers did return with over the 3% level, resulting in large amounts of hazardous waste.

P2 Application:

They trained drivers to check the trailers for heel prior to departure of consignee. As a backup, they trained washrack personnel to look for heel once the trailers returned to the facility, prior to washing. Any significant amount of heel left in the trailer was returned to the shipper or the consignee via transport trailer or 55 gallon drums. The trailers were then washed out; the wash water was tested for hazardous constituents, profiled, and disposed.

Environmental Benefits:

Prior to heel recovery, approximately 740 tons of hazardous waste was disposed of per year. The return of residual chemicals to the customer and the utilization of trailers in dedicated service has virtually eliminated the generation of hazardous waste.

Details of Reductions

Additional Information :

$35,000: 1993 hazardous waste disposal $11,000: 1999 non-hazardous waste disposal (No hazardous waste was generated in 1999) Cost savings for disposal was approximately $24,000 per year. Regulatory relief, increased employee safety, and client benefits
