c) If it is desired to limit the authority granted to the agent, the form may be modified by adding at the end of the first paragraph the statement as follows, and by stating thereafter the extent of the authority granted:

This authority is restricted to the filing of the publications or types of publications set forth below and to the extent shown.

e) If it is desired to give to an agent authority only for the publication of a classification, a classification exceptions tariff, a rules tariff, or any other special kind of tariff, the form may be modified in either of two ways. Omit the words "freight tariffs" and substitute therefor the word or words, "classification," "classification exceptions tariffs," "rules tariffs," etc., or modify so as to authorize the publication of any or all of such tariffs, including rate tariffs.

1. 1) If it is desired to limit the authority granted to publication of a particular tariff or tariffs, this may be done by giving a sufficiently accurate description of the title page of each tariff to identify it and by showing the ILLCC designation if known.
2. 2) If it is intended that the authority granted shall include reissues of specifically named tariffs, that fact should be made clear by adding in the appropriate location "and successive issues thereof."
