However, this partial deletion does not preclude future actions under Superfund. This partial deletion pertains to all of OU4, OU5 and OU7. Operable Unit 2 (OU2), Malta Gulch Tailing Impoundments and Lower Malta Gulch Fluvial Tailing; Operable Unit 8 (OU8), Lower California Gulch; Operable Unit 9 (OU9), Residential Populated Areas; and Operable Unit 10 (OU10), Oregon Gulch, were previously partially deleted from the NPL.

Approval and Promulgation of Air Quality Implementation Plans; Virginia; Removal of Two Operating Permits and a Consent Agreement for the Potomac River Generating Station From the State Implementation Plan
The Environmental Protection Agency (EPA) is taking direct final action to approve revisions to the Commonwealth of Virginia State Implementation Plan (SIP). The revision removes from the Virginia SIP references to two operating permits and a consent agreement for GenOn Potomac River, LLC's Potomac River Generating Station (Potomac River), which was formerly owned by Potomac Electric Power Company. Potomac River has permanently shut down; therefore, the permits and consent agreement are no longer applicable and are being removed from the Virginia SIP. EPA is approving these revisions in accordance with the requirements of the Clean Air Act (CAA).
Approval and Promulgation of Air Quality Implementation Plans; Virginia; Removal of Two Operating Permits and a Consent Agreement for the Potomac River Generating Station From the State Implementation Plan
The Environmental Protection Agency (EPA) proposes to approve the State Implementation Plan (SIP) revision submitted by the Commonwealth of Virginia removing from the Virginia SIP two operating permits and a consent agreement for GenOn Potomac River, LLC's Potomac River Generating Station which was formerly owned by Potomac Electric Power Company. In the Final Rules section of this Federal Register, EPA is approving the Commonwealth's SIP submittal as a direct final rule without prior proposal because the Agency views this as a noncontroversial submittal and anticipates no adverse comments. A detailed rationale for the approval is set forth in the direct final rule. If no adverse comments are received in response to this action, no further activity is contemplated. If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule. EPA will not institute a second comment period. Any parties interested in commenting on this action should do so at this time.
