    (e) Certification of Apportionments.--
        (1) In general.--On October 1 of each fiscal year the Secretary 
    shall certify to each of the State transportation departments the 
    sums which he has apportioned hereunder to each State for such 
    fiscal year, and also the sums which he has deducted for 
    administration pursuant to subsection (a) of this section. To permit 
    the States to develop adequate plans for the utilization of 
    apportioned sums, the Secretary shall advise each State of the 
    amount that will be apportioned each year under this section not 
    later than ninety days before the beginning of the fiscal year for 
    which the sums to be apportioned are authorized, except that in the 
    case of the Interstate System the Secretary shall advise each State 
    ninety days prior to the apportionment of such funds.
        (2) Notice to states.--If the Secretary has not made an 
    apportionment under section 104, 105, or 144 by the 21st day of a 
    fiscal year beginning after September 30, 1998, the Secretary shall 
    transmit, by such 21st day, to the Committee on Transportation and 
    Infrastructure of the House of Representatives and the Committee on 
    Environment and Public Works of the Senate a written statement of 
    the reason for not making such apportionment in a timely manner.

    (f) Metropolitan Planning.--
        (1) Set-aside.--On October 1 of each fiscal year, the Secretary, 
    after making the deduction authorized by subsection (a) of this 
    section, shall set aside not to exceed 1 percent of the remaining 
    funds authorized to be appropriated for expenditure upon programs 
    authorized under this title, for the purpose of carrying out the 
    requirements of section 134 of this title.
        (2) Apportionment to states of set-aside funds.--These funds 
    shall be apportioned to the States in the ratio which the population 
    in urbanized areas or parts thereof, in each State bears to the 
    total population in such urbanized areas in all the States as shown 
    by the latest available census, except that no State shall receive 
    less than one-half per centum of the amount apportioned.
        (3) Use of funds.--The funds apportioned to any State under 
    paragraph (2) of this subsection shall be made available by the 
    State to the metropolitan planning organizations responsible for 
    carrying out the provisions of section 134 of this title, except 
    that States receiving the minimum apportionment under paragraph (2) 
    may, in addition, subject to the approval of the Secretary, use the 
    funds apportioned to finance transportation planning outside of 
    urbanized areas. These funds shall be matched in accordance with 
    section 120(b) unless the Secretary determines that the interests of 
    the Federal-aid highway program would be best served without such 
    matching.
        (4) Distribution of funds within states.--The distribution 
    within any State of the planning funds made available to agencies 
    under paragraph (3) of this subsection shall be in accordance with a 
    formula developed by each State and approved by the Secretary which 
    shall consider but not necessarily be limited to, population, status 
    of planning, attainment of air quality standards, metropolitan area 
    transportation needs, and other factors necessary to provide for an 
    appropriate distribution of funds to carry out the requirements of 
    section 134 and other applicable requirements of Federal law.
        (5) Determination of population figures.--For the purposes of 
    determining population figures under this subsection, the Secretary 
    shall use the most recent estimate published by the Secretary of 
    Commerce.

    (g) Not more than 40 per centum of the amount apportioned in any 
fiscal year to each State in accordance with sections 130, 144, and 152 
of this title may be transferred from the apportionment under one 
section to the apportionment under any other of such sections if such a 
transfer is requested by the State transportation department and is 
approved by the Secretary as being in the public interest. The Secretary 
may approve the transfer of 100 per centum of the apportionment under 
one such section to the apportionment under any other of such sections 
if such transfer is requested by the State transportation department, 
and is approved by the Secretary as being in the public interest, if he 
has received satisfactory assurances from such State transportation 
department that the purposes of the program from which such funds are to 
be transferred have been met. A State may transfer not to exceed 50 
percent of the State's apportionment under section 144 in any fiscal 
year to the apportionment of such State under subsection (b)(1) or 
subsection (b)(3) of this section. Any transfer to subsection (b)(3) 
shall not be subject to section 133(d). Nothing in this subsection 
authorizes the transfer of any amount apportioned from the Highway Trust 
Fund to any apportionment the funds for which were not from the Highway 
Trust Fund, and nothing in this subsection authorizes the transfer of 
any amount apportioned from funds not from the Highway Trust Fund to any 
apportionment the funds for which were from the Highway Trust Fund.
    (h) Recreational Trails Program.--
        (1) Administrative costs.--Whenever an apportionment is made of 
    the sums authorized to be appropriated to carry out the recreational 
    trails program under section 206, the Secretary shall deduct an 
    amount, not to exceed 1\1/2\ percent of the sums authorized, to 
    cover the cost to the Secretary for administration of and research 
    and technical assistance under the recreational trails program and 
    for administration of the National Recreational Trails Advisory 
    Committee. The Secretary may enter into contracts with for-profit 
    organizations or contracts, partnerships, or cooperative agreements 
    with other government agencies, institutions of higher learning, or 
    nonprofit organizations to perform these tasks.
