Moreover, it Is anticipated that a similar situation will develop with respect to the March 31, 1975 deadline. The purpose of these amendments Is to eliminate September 30, 1974 os a deadline date and to extend the March 31, i975 date described above to June 30, 1975. By that time NIOSH will have had an opportunity to review all of the qual ity control plans previously submitted as well as those anticipated to be received.

On April 9, 1074. following a public hearing on the Issue. Part 11 was amended (39 FR 128G4) to provide that until September 30, 1074 respirators ap proved under Part 11 or a Bureau of Mines respirator schedule would be ap proved for use In hazardous atmospheres. Respiratory equipment already in the possession of industrial users or acquired on or before June 30. 1975 and previous ly approved under Bureau of Mines res pirator approval schedules will continue to be approved for use in accordance with the dates adopted in the April 9, 1974 amendments (39 Fit 123G4). Finally, since the requirements for the approved and certification of gas masks are under revision, the deadline date lor the approval of those devices has not been established and those devices have been excepted from the June 39. 1975 dead line date.
