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 were 

mistakenly 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.

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:
