SUPPLEMENTARY INFORMATION: This proposal addresses the Clark County
Transportation Conformity Plan, submitted on April 1, 2008 by the Nevada
Division of Environmental Protection (NDEP) to comply with certain
requirements that apply to the nonattainment portions of Clark County.
In the Rules and Regulations section of this Federal Register, we are
approving this local plan in a direct final action without prior
proposal because we believe this SIP revision is not controversial. If
we receive adverse comments, however, we will publish a timely
withdrawal of the direct final rule and address the comments in
subsequent action based on this proposed rule. Please note that if we
receive adverse comment on an amendment, paragraph, or section of this
rule and if that provision may be severed from the remainder of the
rule, we may adopt as final those provisions of the rule that are not
the subject of an adverse comment.  

We do not plan to open a second comment period, so anyone interested in
commenting should do so at this time. If we do not receive adverse
comments, no further activity is planned. For further information,
please see the direct final action.
