Overview

 

The mixture of dirt, grime and grit that accumulates in sumps is classified as a solid waste sludge and must be appropriately disposed. The types of waste collected in a sump depends upon the type of business that is using the device. For example, car wash residue and material washed into sumps from the floors of vehicle maintenance shops will differ from waste that is placed in floor sumps at industrial facilities. The State of South Dakota presently does not have rules specific to the handling and disposing of sump pit wastes. Therefore, these guidelines have been put together to assist generators and pumpers in making reasonable, environmentally sound decisions when handling these wastes. In doing this, future liability for such wastes can be minimized.


Car Wash and Vehicle Maintennance Shops

 

Based upon experience gained over the years by the Waste Management Program, sump wastes generated by car wash and vehicle maintenance shops are not considered hazardous wastes. An exception to this assumption would be if hazardous waste was placed into the sump for disposal purposes. As a result, unless hazardous waste is known or suspected to be present in the sump, wastes from car wash and vehicle maintenance shops can be considered a solid waste and disposed of in accordance with the recommendations outlined in the table below.


Industrial Facilities

 

Sump wastes generated at industrial facilities will need to be analyzed in order to determine whether the waste would be considered a hazardous waste. For more information regarding the testing requirements and the state’s hazardous waste rules, please contact Carrie Jacobson by e-mail or by calling (605) 773-3153.

 

Although the burden of proper disposal of sump waste lies with the business who generated the waste, sump pump service companies also carry the responsibility of disposing of the waste at a proper site. To document the wastes are properly disposed, the department suggests the following:

 

Sump pump service companies should maintain the following records for each sump or pit that is serviced:

  • The source of the sump waste, the generator/company name and address;
  • A copy of the test results showing the waste is not hazardous, if applicable; and
  • The location of disposal, including the legal description or name of the permitted facility.


If you have new innovative ideas for the handling of sump wastes which will eliminate the problem disposing of large amounts of water or provide a cost effective mechanism for separating the water from the solids, please contact the Waste Management Program.

 

Note: These industrial sump waste guidelines do not apply to domestic waste (septic tanks and/or food related grease traps). For domestic septic tank disposal guidelines click on Septage Requirements.

 

     

    SUMP TYPE

    REQUIRED TESTING

    DISPOSAL OPTIONS

    Car Wash (and similar inert sump waste)
    None
    Vehicle Maintennance Sumps and Pits
    Because it has been DENR’s experience that a majority of sump wastes from vehicle maintenance operations are not hazardous wastes, it is not necessary for these businesses to conduct hazardous waste testing of this waste stream. However, should the business have knowledge that a potential hazardous waste has been placed in a sump or pit, an analysis may be required. Please contact the Hazardous Waste Program for guidance regarding testing needs.

    As a non-hazardous solid waste the sludge may be disposed of using one of the following options:

     

    Industrial Sumps and Pits Appropriate methods must be used to document whether the waste would be considered a hazardous waste. Please contact the Hazardous Waste Program for assistance. Disposal options are determined based upon whether the waste is considered a hazardous or non-hazardous waste.
