DOT Small Quantity Exception

(Section 7 of the "Hazardous Material Transportation" APS User Policy & Procedure APS_1410268)

Small Quantity Exception

The Argonne Transportation Safety Board approved the on-site hazardous material (HazMat) transportation by APS users, if done in compliance with Department of Transportation (DOT) Small Quantity Exceptions (49 CFR 173.4).The Laboratory allows:

  1. If transported in full conformance with DOT regulations, the entry of small quantities of nonradioactive qualifying materials at any gate. [Refer to Table below for qualifying materials and quantity limits.]
  2. If transported in full conformance with DOT regulations, the transport of small quantities of nonradioactive qualifying materials in user-driven vehicles across the Argonne site to the user facilities at the APS.
  3. If prepared for transport in full conformance with the DOT regulations, the off-site transport of nonradioactive qualifying materials without the involvement of Argonne personnel.

See Table 2 for a summary of the maximum quantities of materials that can be transported under the small quantity exception for various classes/divisions of hazardous materials.

No exception from the existing Argonne standards for handling radioactive materials was approved. All radioactive materials are to be transported to and from the APS in accordance with Argonne requirements (e.g., receipt at Building 46, on-site transfers by Argonne MC&A, off-site shipment by Argonne Facility Management Services, etc.).

Materials that are synthesized at Argonne and that have unknown hazards, and/or hazards not present in any of the reactants, must be reviewed and the hazards indentified by Argonne-trained hazardous materials personnel prior to transport off the Argonne site. Also, for outbound user transport of hazardous materials, materials with different hazard classification shall be packaged in separate packages (i.e., only one hazard classification per package).

A standard packaging that meets the DOT small quantity requirements (49 CFR 173.4) is available to the users through the APS stockroom.

The APS, with the support of Argonne, coordinates training of the APS CAT/CDTs and XSD personnel on hazardous materials transportation requirements.The APS relies on the Argonne Training Management System to record user training and will provide training information upon request.

Users should be aware that there are additional requirements and restrictions that apply to the movement of materials by air and other common carriers.

Users also may arrange for a carrier to pick up these small quantity exception shipments, but they must be designated for "ground transportation only."
