(a) Awards will be based on rates customarily charged by persons engaged in the business of acting as attorneys, agents and expert witnesses, even if the services were made available without charge or at a reduced rate to the applicant.

(b) No award for the attorney or agent fees under these Rules may exceed $75 per hour. However, an award may also include the reasonable expenses of the attorney, agent, or witness as a separate item, if the attorney, agent, or expert witness ordinarily charges clients separately for such expenses.

(c) In determining the reasonableness of the fee sought for an attorney, agent, or expert witness, the following matters will be considered:

(1) If the attorney, agent, or expert witness is in practice, that person's customary fee for similar services, or, if an employee of the applicant, the fully allocated cost of the services;

(2) The prevailing rate for similar services in the community in which the attorney, agent, or expert witness ordinarily performs services;

(3) The time actually spent in the representation of the applicant; and

(4) The time reasonably spent in light of the difficulty or complexity of the issues in the adversary adjudicative proceeding.

(d) The reasonable cost of any study, analysis, engineering report, test, project or similar matter prepared on behalf of an applicant may be awarded, to the extent that the charge for the service does not exceed the prevailing rate for similar services, and the study or other matter was necessary for preparation of the applicant's case.
