Re: Vehicle and equipment washes


U.S. EPA recently published the final Effluent Limitations Guidelines, Pretreatment Standards, and New Source Performance Standards for the Transportation Equipment Cleaning (TEC) Point Source Category (Federal Register, August 14, 2000).  

According to U.S. EPA estimates, there are over 1,200 TEC facilities in the U.S. that may be subject to this rule.This new wastewater rule establishes effluent limits for facilities

This new wastewater rule establishes effluent limits for facilities that generate wastewater from the cleaning the interior of tank trucks, closed-top hopper trucks, rail tank cars, intermodal tank containers, inland tank barges, closed-top hopper barges, ocean/sea tankers, and other similar tanks (excluding drums and intermediate bulk containers used to transport materials or cargos that come into direct contact with the tank or container interior.

TEC wastewaters include washwaters  which have come into direct contact with the tank or container interior including pre-rinse cleaning solutions, chemical cleaning solutions, and final rinse solutions.  Additionally, the rule covers wastewater generated  from washing vehicle exteriors, equipment and floor washings, and TEC contaminated wastewater for  those facilities subject to the TEC rule.

Facilities that discharge less than 100,000 gallons per year of TEC process wastewater are excluded from this rule.  This may encourage facilities to implement  water conservation measures.The new rule offers a pollution prevention (P2) alternative to complying with  numeric pollutant limitations for several categories established by the rule.  Facilities can prepare "Pollutant Management Plans" as an alternative.  These P2-based plans must contain: provisions for appropriate recycling or reuse of cleaning agents; provisions for minimizing the use of toxic cleaning agents; and provisions for recycling or reuse of segregated heels and pre-rinse/pre-steam wastes.

The compliance deadline for existing TEC facilities discharging into publicly-owned treatment works (POTWs) is as soon as possible, but no later than August 14, 2003.

According to data collected by U.S. EPA, approximately 27% of TEC facilities currently practice water pollution prevention, and approximately 61% of TEC facilities currently practice heel pollution prevention.  In the TEC industry, "heel" means any material remaining in a tank following unloading, delivery, or discharge of the of the transported cargo.

The Technical Development Document for the rule provides additional information on pollution prevention controls and flow reduction technologies. This information can be used to develop the Pollutant Management Plans.

The development document along with the final rule is available from U.S. EPA's Office of Water homepage at: http://www.epa.gov/OST/guide/teci 

Hope this helps,

Hi all,

Does anyone have a fact sheet(s) developed (p2 ideas or regulatory requirements on) for vehicle and equipment washes? This involves discharge water from washing exteriors of vehicles and equipment and its related contaminants of lubricating oils, antifreeze, gasoline, and washing the interior of vessels used to transport fuel products or chemicals. Aquifer protection permits are normaly required for this activity.
