**Naval Surface Warfare Center, Potomac River, Dahlgren, VA; Danger** 
**Zone**

**AGENCY :**  United States Army Corps of Engineers, Department of Defense.

**ACTION :**  Notice of proposed rulemaking and request for comments.

**SUMMARY :**  The Corps of Engineers is proposing to amend an existing permanent danger zone in the waters of the Upper Machodoc Creek and the Potomac River in the vicinity of Dahlgren in King George County, Virginia. The Naval Surface Warfare Center, Dahlgren conducts research, development, testing and evaluation of national defense systems on the Potomac River Test Range. Many of the tests are hazardous operations presenting a danger to persons or property in the danger zone. The proposed amendment is necessary to protect the public from hazardous operations such as firing large and small caliber guns and projectiles, aerial bombing, use of directed energy and operating manned or unmanned watercraft. The proposed amendment adds a 100-yard buffer to the Middle Danger Zone to prevent public contact with unexploded ordnance along the
shoreline of Naval Surface Warfare Center, Dahlgren within this zone.

**DATES :**  Written comments must be submitted on or before December 10,

2010.

**FOR FURTHER INFORMATION CONTACT :**  Mr. David Olson, Headquarters, Operations and Regulatory Community of Practice, Washington, DC at 202–761–4922, or Mr. Robert Berg, Corps of Engineers, Norfolk District, Regulatory Branch, at

757–201–7793.

**SUPPLEMENTARY INFORMATION :**  Pursuant
to its authorities in Section 7 of the Rivers and Harbors Act of 1917 (40 Stat. 266; 33 U.S.C. 1) and Chapter XIX of the Army Appropriations Act of 1919 (40 Stat. 892; 33 U.S.C. 3), the Corps of Engineers proposes to amend its regulations at 33 CFR part 334 for a permanent danger zone in the waters of Upper Machodoc Creek and the Potomac River in the vicinity of Naval Surface Warfare Center, Dahlgren in King George County, Virginia. The Naval Surface Warfare Center, Dahlgren conducts research, development, testing
and evaluation of national defense systems on the Potomac River Test Range. Many of the tests are hazardous operations presenting a danger to persons or property in the danger zone. The proposed modification of the existing permanent danger zone is necessary to protect the public from hazardous operations such as firing large and small caliber guns and projectiles, aerial bombing, use of directed energy, and operating manned or unmanned watercraft. The proposed modification adds a 100-yard buffer to the Middle Danger Zone to prevent public contact with unexploded ordnance along the shoreline of Naval Surface Warfare Center, Dahlgren within this danger zone. The proposed modification will: (1) Expand the description of continuing hazardous operations in the danger zone to include firing of large or small caliber guns and projectiles, aerial bombing, use of directed energy technology, and
manned or unmanned water craft operations; (2) change the latitude and longitude references to correspond to NAD83 without changing the boundaries themselves, except in the case of the point at 38 ° 17 ′ 54 ′′

, –77 ° 01 ′02 ′′ to move the reference point from neighboring property to Naval Surface Warfare Center, Dahlgren property; (3) expand the Middle Danger Zone further into Upper Machodoc Creek where operations involving directed energy, watercraft maneuvers, and transport of explosives are conducted; (4) add a 100-yard buffer to prevent public contact with unexploded ordnance along the shoreline of Naval Surface Warfare Center, Dahlgren within the Middle Danger Zone; (5) extend normal hours of hazardous operations from 4 p.m. to 5 p.m.; and (6) provide for continued use of the naval facility shoreline for commercial fishing and waterfowl hunting blinds under existing Navy and state regulations.

The current regulation authorizes Naval Surface Warfare Center, Dahlgren to restrict watercraft from entering or leaving Upper Machodoc Creek. The amendment will allow patrol boats to engage watercraft desiring to leave Upper Machodoc Creek a few hundred yards farther west before they get to the existing danger zone boundary at the
mouth of the creek. The restriction will be in place 24 hours a day, seven days
a week.

Procedural Requirements

a. Review Under Executive Order 12866

This proposed rule is issued with respect to a military function of the Defense Department and the provisions of Executive Order 12866 do not apply.

b. Review Under the Regulatory Flexibility Act

This proposed rule has been reviewed under the Regulatory Flexibility Act (Pub. L. 96–354) which requires the preparation of a regulatory flexibility analysis for any regulation that will have a significant economic impact on
a substantial number of small entities (i.e., small businesses and small governments). Unless information is obtained to the contrary during the public notice comment period, the Corps expects that the economic impact of the amendment of this danger zone would have practically no impact on the public, no anticipated navigational hazard or interference with existing waterway traffic. This proposed rule, if adopted, will have no significant economic impact on small entities.

c. Review Under the National Environmental Policy Act

Due to the administrative nature of
this action and because there is no intended change in the use of the area, the Corps expects that this regulation, if adopted, will not have a significant impact to the quality of the human environment and, therefore, preparation of an environmental impact statement will not be required. An environmental assessment will be prepared after the public notice period is closed and all
comments have been received and
considered. It will be available from the
District office listed at the end of **FOR**

**FURTHER INFORMATION CONTACT** , above.

d. Unfunded Mandates Act

This proposed rule does not impose an enforceable duty among the private sector and, therefore, it is not a Federal private sector mandate and it is not subject to the requirements of either
Section 202 or Section 205 of the
Unfunded Mandates Act. We have also found under Section 203 of the Act, that small governments will not be significantly and uniquely affected by this rulemaking.

List of Subjects in 33 CFR Part 334

Danger zones, Marine safety, Navigation (water), Restricted areas, Waterways.

For the reasons set out in the preamble, the Corps proposes to amend 33 CFR part 334 as follows:

**PART 334—DANGER ZONE AND**
**RESTRICTED AREA REGULATIONS**

2. Revise paragraph (a) of § 334.230 to
read as follows:

Deep-draft vessels using dredged channels and propelled by mechanical power at a speed greater than five miles per hour may proceed directly through the danger zones without restriction except when notified to the contrary by the patrol boat. Unless instructed to the contrary by the patrol boat, small craft navigating up or down the Potomac River during hazardous operations shall proceed outside of the northeastern boundary of the Middle Danger Zone. All craft desiring to enter the Middle Danger Zone when proceeding in or out of Upper Machodoc Creek during hazardous operations will be instructed by the patrol boat; for those craft that desire to proceed in or out of Upper
