The Secretary of Labor is specifically authorized to prescribe
certain regulations (generally relating to hour of service, year of
service, break in service, year of participation and special rules for
seasonal and maritime industries) applicable to both title I of the Act
and sections 410 and 411 of the Code. These regulations are contained in
this subpart (A) and subpart B of this part (2530) and must be
integrated with regulations prescribed by the Secretary of the Treasury
or his delegate under sections 410 of the Code (relating to minimum
participation standards), 411(a) of the Code (relating to minimum
vesting standards) and 411(b) of the Code (relating to benefit accrual
requirements). The allocation of regulatory jurisdiction between the
Secretary of Labor and the Secretary of the Treasury or his delegate is
governed by titles I through III of the Act. See section 3002 of the Act
(88 Stat. 996).
