(a) Conditions of reweighing. A licensed weighmaster may not reweigh or issue a weighmaster’s certificate for solid fuel unless the motor vehicle operator has surrendered the original and duplicate weighmaster’s certificates in his possession pertaining to the solid fuel. These certificates shall be attached by the weighmaster to the scale copy of the new weighmaster’s certificate. The new weighmaster’s certificate shall be issued and maintained in a manner that the new certificate and any prior certificates may be easily reconciled. A duplicate copy may be returned to the operator of vehicle if the duplicate copy of the weighmaster’s certificate is obliterated with a rubber stamp using the following legend:

This solid fuel has been reweighed and this certificate should not be accepted. Any attempt to use this certificate to deliver solid fuel should be reported to your local or State inspector of weights and measures at once.
