Inspection Criteria

LEVEL VI Vehicle Inspection Standards*

Prior to dispatch from a DOE generator site, all WIPP vehicles must be defect-free. These vehicles will be held to a higher standard than all other commercial shipments of hazardous materials. All vehicles traveling in the United States must meet the Commercial Vehicle Safety Alliance’s (CVSA) North American Standard. The CVSA has developed the LEVEL VI North American Standard that will be applied to WIPP shipments. The LEVEL VI North American Standard demands that the WIPP vehicle be DEFECT-FREE before it can depart or continue transport of radioactive wastes. In addition to being inspected before departure, the WIPP vehicles will be inspected periodically along the route by state inspectors that have been specially trained in the enhanced procedures.

The table below identifies minimum standards and out-of-service criteria established for commercial vehicles. The North American Uniform (NAU) Standards were established by the Commercial Vehicle Safety Alliance (CVSA), an association of state, provincial and federal officials responsible for the administration and enforcement of motor carrier safety laws in the United States, Canada and Mexico. Every jurisdiction in North America has adopted and enforces the NAU standards for commercial vehicles. The standardization of the inspection criteria for commercial vehicles promotes safe and efficiency in the transportation of goods throughout North America. When a commercial vehicle enters a new jurisdiction and an inspector sees a recent CVSA NAU decal, they know that vehicle has met CVSA’s inspection standards.

The LEVEL VI North American Uniform Inspection Procedures and Out-of-Service Criteria identified here are part of a program developed by CVSA for the U.S. Department of Energy. The LEVEL VI standards are to be used only by inspectors trained in the LEVEL VI NAU Inspection Procedures and are used only on designated shipments (e.g., WIPP shipments) approved by the Department of Energy. They are not part of CFR 49 Federal Regulations, but DOE has agreed to abide by this strict criteria to promote the safety of radioactive shipments. If a WIPP shipment does not meet one of the criteria below, it will be placed out-of-service until the defect is corrected.

ITEM TO BE INSPECTED

NORTH AMERICAN
UNIFORM  CRITERIA

LEVEL VI NORTH AMERICAN UNIFORM  CRITERIA
(e.g., WIPP SHIPMENTS)

Radiation Inspection Not required Complete radiological inspection performed. The vehicle will be placed out of service if it exceeds DOT-established radiation limits.
Driver must provide:  Operator’s License, Medical Certificate, Vehicle Registration, Log Books, Permits, Shipping Papers, Written Route Plan, Training Certificate, Driver/Vehicle Daily Inspection Report and DOT Hazardous Materials Registration. Required Required

PART I. DRIVER INSPECTION STANDARDS (Also see WIPP Driver Qualification Criteria)

Policy Statement

The purpose of Part I is to identify violations that render the commercial motor vehicle operator unqualified to drive or out-or-service. The necessity for all enforcement personnel to implement and adhere to these standards is: a matter of law; perceived as necessary by the society we are charged with protecting; and are a professional obligation if substantial enhancement in the safety of commercial motor vehicle operators is to be achieved.

Except where state, provincial or federal laws preclude enforcement of a named item, motor carrier safety enforcement personnel and their jurisdictions shall comply with these driver out-of-service violation standards.

Out-of-Service Violation: Violation under this category preclude enforcement of a named item, motor carrier safety enforcement personnel and their jurisdictions shall comply with these driver out-of-service violation standards.

Enhanced Policy Statement: In addition to the North American Uniform Driver Out-of-Service Criteria Policy Statement, the purpose of this part is to ensure the safe and efficient transportation of transuranic, spent nuclear fuel and high-level radioactive waste. As such, the operators of commercial motor vehicles involved in this type of transportation play a critical role toward ensuring public safety. The violations listed as out-of-service in this part preclude further operation of a commercial motor vehicle by its driver for a specified period of time or, for some violations, until a required condition is met.

The enhanced inspection and out-of-service criteria listed in this part are to be used only by inspectors trained in the Enhanced NAU inspection Procedures and used only on designated shipments approved by the Department of Energy.

Part II. Vehicle Inspection

Policy Statement

The purpose of this part is to identify critical vehicle inspection items and provide criteria for placing vehicles out-of-service subsequent to a safety inspection.

NOTE: Decal Qualification: Each vehicle must “pass” inspection to qualify for a decal. “Pass Inspection” means that no violations/defects are found of the vehicle inspection items contained in the definitions of Level I and Level V inspections. Said definitions of Level I and Level V inspections can be fount in Article XVIII of the CVSA Bylaws. For the purpose of decal issuance, if no violation is detected during a Level I or Level V inspection due to a hidden part, which includes the vehicle inspection items listed in the definitions, a decal shall be applied.

OUT-OF-SERVICE: Authorized personnel shall declare and mark “out of service” any motor vehicle which by reason of its mechanical condition or loading would be likely to cause an accident or breakdown. An “Out of Service Vehicle” sticker shall be used to mark vehicles “out of service.” No motor carrier shall require nor shall any person operate any commercial motor vehicle declared and marked “out of service” until all repairs required by the “out of service notice” have been satisfactorily completed.

No person shall remove the “Out of Service Vehicle” sticker from any motor vehicle prior to completion of all repairs required by the “out of service notice.”

Violations, other than out-of-service conditions, detected during the inspection process will not preclude the completion of the current trip or dispatch. However, such violations must be corrected or repaired prior to re-dispatch.

Enhanced Policy Statement: The enhanced out-of-service criteria listed in this part are to be used only be inspectors trained in the Enhanced NAU Inspection Procedures and used only on designated shipments approved by the Department of Energy.

Part III. HAZARDOUS MATERIALS INSPECTION STANDARDS

Policy Statement

The purpose of the NAU Hazardous Materials is to provide criteria for the abatement of unsafe conditions in the transportation of hazardous materials and is based upon the presence of any condition(s) which fail(s) to communicate the hazards(s) or is an imminent hazard.

Conditions categorized as “out-of-service” shall not be allowed to continue in commerce until the condition(s) is/are corrected and the shipment complies with the applicable regulations. If, at the discretion of the inspector, it is less hazardous to the public to relocate the vehicle, it shall be towed, transported, or escorted to a safe location only at the direction of an official authority.
