(c) In any case where compliance with any of these rules introduces unusual difficulty, such rule may be temporarily waived by the Commission upon application of the utility. If in such case compliance with the rule would cost more than the results of such compliance are worth to the public and consumers of electric current, it may be permanently set aside by the Commission.
