photochemical grid modeling that the State conducted in 2008. (Photochemical grid modeling is used to project future 8-hour ozone Design Values for comparison to the 85.0 ppb ozone NAAQS.) On July 21, 2010, we proposed to act on the State’s revisions and as part of that action, proposed to approve Colorado’s attainment demonstration and certain other aspects of the revisions, and proposed to disapprove other aspects of the revisions. For further information on Colorado’s submittal and our proposed action, please consult the Federal Register (July 21, 2010; 75 FR 42346).

On October 7, 2010, Colorado submitted revised photochemical modeling results to us for the DMA/NFR ozone SIP. Colorado re-ran the photochemical model because in September 2010 the State discovered that errors had been made in specifying the location of certain point sources in the 2008 modeling. Latitude/longitude locations for some point sources in the original modeling effort weremistakenly derived using the degreeminute-second coordinate system rather than the correct decimal degree coordinate system. As a result, some point source locations were displaced in the grid-coordinate system used by the model. Thus, Colorado re-ran the model with the correct coordinates to determine whether the errors made in locating some point sources affected the reliability of the model results.

The projected Design Values for 2010 resulting from the revised modeling remain below the 85.0 ppb ozone NAAQS. For the SIP’s 2010 base case, the revised modeling’s maximum projected 8-hour ozone Design Values are found at the Rocky Flats North and Fort Collins West monitoring sites—84.7 ppb ozone at both locations in 2010. This is 0.2 ppb lower than the State’s 2008 modeling projected using incorrect point source locations. Because it produced slightly lower values at the monitoring sites with maximum Design Values, the revised modeling supports the conclusions that EPA proposed regarding the 2008 modeling.

With this Notice of Data Availability, we are providing an opportunity for the public to comment on Colorado’s October 2010 revised modeling, including comments on how it may affect EPA’s proposed determinations as reflected in our July 21, 2010 proposal. We are not re-opening the comment period on the material that was before the Agency at the time of the July 21, 2010 proposal.

Colorado’s October 2010 revised modeling is reflected in the following two documents, which we have added to the rulemaking docket:

1. Final 2010 Ozone Attainment Demonstration Modeling for the Denver 8- Hour Ozone State Implementation Plan. Docket Number: EPA–R08–OAR–2010–0285–
0025.

2. MEMORANDUM, October 7, 2010: ENVIRON: Denver Final 2010 Ozone Attainment Demonstration Modeling using Correct Point Source Locations. Docket Number: EPA–R08–OAR–2010–0285–0043.

We will take final action based on our notice of proposed rulemaking that was published in the Federal Register on July 21, 2010 (75 FR 42346), the comments we received on that proposal, Colorado’s October 2010 revised modeling, and any comments we receive in response to this NODA.

**Approval and Promulgation of State Air Quality Plans for Designated**  **Facilities and Pollutants; Commonwealth of Virginia; Control of**  **Emissions From Existing Hospital/ Medical/Infectious Waste Incinerator**  **(HMIWI) Units, Negative Declaration and Withdrawal of EPA Plan Approval** 

**AGENCY :**  Environmental Protection Agency (EPA).

**ACTION :**  Proposed rule.

**SUMMARY :**  EPA proposes to approve the Commonwealth of Virginia’s negative declaration and request for EPA withdrawal of its section 111(d)/129 plan (the plan) approval for HMIWI units. Submittal of a negative declaration or State plan revision is a requirement of the Clean Air Act (CAA). In the Final Rules section of this Federal Register , EPA is approving the Commonwealth of Virginia’s negative declaration and request for EPA withdrawal of its plan approval for HMIWI units. 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.

**DATES :**  Comments must be received in writing by January 18, 2011.

**SUPPLEMENTARY INFORMATION :**  A. Background

The Department of the Treasury is in the process of reviewing and updating all of its acquisition policies. As part of this policy review, the Office of the Procurement Executive (OPE) is updating and using as point of reference the Department of the Treasury Acquisition Regulation (DTAR) 2002 Edition, first published on June 14, 2002, and currently posted at:http:// www.access.gpo.gov/nara/cfr/. Only regulatory guidance is being published for public comment. Once adopted as a final rule, the DTAR will be maintained separately and combined with Department of the Treasury Acquisition Procedures (DTAP) for expediency of use by Treasury staff. The DTAR and combined DTAR/DTAP will be posted
at: http://www.treasury.gov/about/ organizational-structure/offices/Mgt/Pages/ProcurementPolicyRegulations.aspx. B. This Proposed Rule

The following describes Treasury’s proposed changes to 48 CFR Chapter 10:

Subpart 1001.3 AGENCY ACQUISITION REGULATIONS was added to restate the policy that the DTAR applies throughout the Department of the Treasury except for the US Mint, and that OPE is responsible for the DTAR’s evaluation, review and issuance.

Subpart 1001.4 DEVIATIONS FROM THE FAR was added, stating that the Senior Procurement Executive (SPE) is authorized to approve individual contract and class deviations from the FAR and DTAR.

Subpart 1001.6 CAREER DEVELOPMENT, CONTRACTING AUTHORITY AND RESPONSIBILITIES was added to link by reference and insert in this subpart DTAR 1052.201– 70 on Contracting Officer’s Technical Representative (COTR) appointment and authority, with the requirement that substantially the same clause be included in all solicitations and
contracts.

Editorial and clarification changes were made to section 1001.104 to make it easier for contractors, offerors and Treasury contracting staff to read and

use.

Sections 1001.301, 1001.304, 1001.403, 1001.404, 1002.70, 1052.201– 70, and 1052.219–73 supplement the FAR by providing paragraph specific designations, delegations of authority within Treasury and/or changed names of offices due to reorganization.

Under Part 1002 DEFINITIONS OF WORDS AND PHRASES definitions were added for:

• All Bureaus and their corresponding

acronyms

• Contracting Activity

• Head of Contracting Activity (HCA)

• Head of the Agency

Full definitions were likewise added for the following abbreviations:
