Dear Mr. Grey:

This is in response to your letter of February 4, 2000concerning mounting an MC306 cargo tank onto a new chassis under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-80).  Specifically you asked if an MC306 AL cargo tank mounted onto a new chassis, certified by a Design Certifying Engineer, with changes in the bolster mounts to comply with newer MC306 AL tanks could continue to be registered as an MC306 AL cargo tank.

The answer is yes.  A cargo tank mounted onto a new chassis is not considered a new, cargo tank, thus could be continued to be an MC306 AL cargo tank if all applicable regulations are followed in
  § 180.413.

I hope this satisfies your request.
