**SUPPLEMENTARY INFORMATION:**
Throughout this document, “we,” “us” and “our” refer to the EPA. This proposal addresses the following local rule: Clark County DES Section 4, Control Officer, revised 12/17/19 and submitted 3/16/20. Elsewhere, in the Rules and Regulations section of this *Federal Register**,* we are approving the local rule 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.
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.
Dated: April 13, 2022.

Acting Regional Administrator, Region IX.
