(a)(1)(i) No award for the fee of an attorney or agent under this part may exceed $125.00 per hour, or for adversary adjudications commenced prior to March 29, 1996, $75.00 per hour, indexed to reflect cost of living increases as follows:

(ii) The cost of living index to be used is the Consumer Price Index, All Urban Consumers, U.S. City Average, All Items (CPI-U). If legal services are provided during more than one year, each year shall be calculated separately. If an annual average CPI-U for a particular year is not yet available, the prior year's annual average CPI-U shall be used.

(2) No award to compensate an expert witness may exceed the highest rate that the Authority pays expert witnesses. However, an award may also include the reasonable expenses of the attorney, agent, or witness as a separate item, if the attorney, agent, or witness ordinarily charges clients separately for such expenses.

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

(1) If the attorney, agent or witness is in practice, his or her 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 witness ordinarily performs services;

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

(4) The time reasonably spent in light of the difficulty or complexity of the issues in the proceeding; and

(5) Such other factors as may bear on the value of the services provided.

(c) The reasonable cost of any study, analysis, engineering report, test, project or similar matters 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.
