Thereafter, the Director shall, from time to time, make such surveys, general or local, as the conference shall deem expedient.
((2)) In the course of any survey, the Director shall take into account local conditions in each judicial district, including the areas and the populations to be served, the transportation and communications facilities available, the amount and distribution of business of the type expected to arise before officers appointed under this chapter (including such matters as may be assigned under section 636(b) of this chapter), and any other material factors. The Director shall give consideration to suggestions from any interested parties, including district judges, United States magistrate judges or officers appointed under this chapter, United States attorneys, bar associations, and other parties having relevant experience or information.
((3)) The surveys shall be made with a view toward creating and maintaining a system of full-time United States magistrate judges. However, should the Director find, as a result of any such surveys, areas in which the employment of a full-time magistrate judge would not be feasible or desirable, he shall recommend the appointment of part-time United States magistrate judges in such numbers and at such locations as may be required to permit prompt and efficient issuance of process and to permit individuals charged with criminal offenses against the United States to be brought before a judicial officer of the United States promptly after arrest.
((b)) ** .—** Upon the completion of the initial surveys required by subsection (a) of this section, the Director shall report to the district courts, the councils, and the conference his recommendations concerning the number of full-time magistrates and part-time magistrates, their respective locations, and the amount of their respective salaries under . The district courts shall advise their respective councils, stating their recommendations and the reasons therefor; the councils shall advise the conference, stating their recommendations and the reasons therefor, and shall also report to the conference the recommendations of the district courts.

Such determinations shall take effect in each judicial district at such time as the district court for such judicial district shall determine, but in no event later than one year after they are promulgated.
((c)) ** .—** Except as otherwise provided in this chapter, the conference may, from time to time, in the light of the recommendations of the Director, the district courts, and the councils, change the number, locations, and salaries of full-time and part-time magistrate judges, as the expeditious administration of justice may require.
