injury criterion (HIC) unlimited score in

excess of 1000 is acceptable, provided

the HIC15 score (calculated in

accordance with 49 CFR 571.208) for

that contact is less than 700.

b. Body-to-Wall/Furnishing Contact

If a seat is installed aft of structure

(e.g., an interior wall or furnishing) that

does not provide a homogenous contact

surface for the expected range of

occupants and yaw angles, then

additional analysis or tests may be

required to demonstrate that the injury

criteria are met for the area that an

occupant could contact. For example, if

different yaw angles could result in

different airbag performance, then

additional analysis or separate tests may

be necessary to evaluate performance.

c. Neck-Injury Criteria

The seating system must protect the

occupant from experiencing serious

neck injury. The assessment of neck

injury must be conducted with the

airbag device activated, unless there is

reason to also consider that the neck-

injury potential would be higher for

impacts below the airbag-device

deployment threshold.

(1) The N

(calculated in accordance

with 49 CFR 571.208) must be below

1.0, where N

= F

+ M

, and N

critical values are:

(a) F

= 1,530 lb for tension

(b) F

= 1,385 lb for compression

= 229 lb-ft in flexion

(d) M

= 100 lb-ft in extension

(2) In addition, peak F

must be below

937 lb in tension and 899 lb in

compression.

(3) Rotation of the head about its

vertical axis, relative to the torso, is

limited to 105 degrees in either

direction from forward-facing.

(4) The neck must not impact any

surface that would produce

concentrated loading on the neck.

d. ATD and Test Conditions

Longitudinal tests conducted to

measure the injury criteria above must

be performed with the FAA Hybrid III

ATD, as described in SAE 1999–01–

1609, ‘‘A Lumbar Spine Modification to

the Hybrid III ATD for Aircraft Seat

Tests.’’ The tests must be conducted

with an undeformed floor, at the most-

critical yaw cases for injury, and with

all lateral structural supports (e.g.

armrests or walls) installed.

Note: Applicant must demonstrate

that the installation of seats via plinths

or pallets meets all applicable

requirements. Compliance with the

guidance contained in policy

memorandum PS–ANM–100–2000–

00123, ‘‘Guidance for Demonstrating

Compliance with Seat Dynamic Testing

for Plinths and Pallets,’’ dated February

2, 2000, is acceptable to the FAA.

2. The structure-mounted airbag must

provide adequate protection for each

occupant regardless of the number of

occupants of the seat assembly.

3. The structure-mounted airbag

system must not be susceptible to

inadvertent deployment as a result of

wear and tear, or inertial loads resulting

from in-flight or ground maneuvers

(including gusts and hard landings)

likely to be experienced in service.

4. The applicant must demonstrate

that an inadvertent deployment that

could cause injury to a standing or

sitting person is improbable. Inadvertent

deployment must not cause injury to

anyone who may be positioned close to

the structure-mounted airbag (e.g.,

seated in an adjacent seat, or standing

adjacent to the airbag installation or the

subject seat). Cases where a structure-

mounted airbag is inadvertently

deployed near a seated occupant or an

empty seat must be considered.

5. Inadvertent deployment of the

structure-mounted airbag during the

most critical part of flight will either not

cause a hazard to the airplane or is

extremely improbable.

6. Deployment of the structure-

mounted airbag must not introduce

hazards or injury mechanisms to the

seated occupant, including occupants in

the brace position. Deployment of the

structure-mounted airbag must also not

result in injuries that could impede

rapid exit from the airplane.

7. Effects of the deflection and

deformation of the structure to which

the airbag is attached must be taken into

account when evaluating deployment

and location of the inflated airbag. The

effect of loads imposed by airbag

deployment, or stowed components

where applicable, must also be taken

into account.

8. The applicant must demonstrate

that the structure-mounted airbag, when

deployed, does not impair access to the

seatbelt- or harness-release means, and

must not hinder evacuation. This will

include consideration of adjacent seat

places and the aisle.

9. The airbag, once deployed, must

not adversely affect the emergency-

lighting system, and must not block

escape-path lighting to the extent that

the light(s) no longer meet their

intended function.

10. The structure-mounted airbag

must not impede occupants’ rapid exit

from the airplane 10 seconds after its

deployment.

11. Where structure-mounted airbag

systems are installed in or close to

passenger evacuation routes (other than

for the passenger seat for which the

airbag is installed), possibility of impact

on emergency evacuation (e.g., hanging

in the aisle, potential trip hazard, etc.)

must be evaluated.

12. The airbag electronic system must

be designed to be protected from

lightning per § 25.1316(b), and high-

intensity radiated fields per

§ 25.1317(c).

13. The structure-mounted airbag

system must not contain or release

hazardous quantities of gas or

particulate matter into the cabin.

14. The structure-mounted airbag

installation must be protected from the

effects of fire such that no hazard to

occupants will result.

15. The inflatable bag material must

meet the 2.5-inches-per-minute

horizontal flammability test defined in

14 CFR part 25, appendix F, part I,

paragraph (a)(1)(iv).

16. The design of the structure-

mounted airbag system must protect the

mechanisms and controls from external

contamination associated with that

which could occur on or around

passenger seating.

17. The structure-mounted airbag

system must have a means to verify the

integrity of the structure-mounted airbag

activation system.

18. The applicant must provide

installation limitations to ensure

installation compatibility between the

seat design and opposing monument or

structure.

NPRM Notice of proposed rulemaking

§ Section

U.S.C. United States Code

II. Background, Purpose, and Legal

Basis

On February 17, 2021, the National

Geospatial-Intelligence Agency (NGA)

notified the Coast Guard that it will be

conducting U.S. Government training

and systems testing from 9 a.m. on April

25, 2021, through 10 p.m. on May 8,

2021. The training and testing will take

place in two locations offshore of Ocean

City, MD. The COTP Maryland-National

Capital Region has determined that a

security zone is needed for waterborne

protection of the public, mitigation of

potential terrorist acts, and the

enhancing of public and maritime safety

and security in order to safeguard life,

property, and the environment on or

near the navigable waters near Ocean

City, MD.

The purpose of this rulemaking is to

ensure the security of vessels and

government equipment involved in this

event by prohibiting vessels from

entering the security zone. If a person or

vessel has been granted permission to

enter the zone, they must not enter

waters within 1,000 yards of the on

scene Coast Guard vessel or test

equipment being used by Coast Guard

personnel. The Coast Guard is

proposing this rulemaking under

authority in 46 U.S.C. 70034 (previously

33 U.S.C. 1232).

III. Discussion of Proposed Rule

The COTP is proposing to establish a

security zone from 9 a.m. on April 25,

2021, through 10 p.m. on May 8, 2021.

The security zone will be enforced from

9 a.m. to 10 p.m. on April 25, 2021, and

those same hours on April 26, 2021,

April 27, 2021, April 28, 2021, April 29,

2021, April 30, 2021, May 1, 2021, May

2, 2021, May 3, 2021, May 4, 2021, May

5, 2021, May 6, 2021, May 7, 2021 and

May 8, 2021. The security zone will

cover all waters of the North Atlantic

Ocean, from surface to bottom,

encompassed by a line connecting the

following points beginning at 38°23′56″

N, 074°48′06″ W, thence south to

38°21′40″ N, 074°48′33″ W, thence south

to 38°17′54″ N, 074°49′57″ W, thence

southwest to 38°15′04″ N, 074°51′44″ W,

thence northwest to 38°18′52″ N,

074°54′24″ W, thence north to 38°22′55″

N, 074°52′44″ W, and northeast back to

the beginning point. The zone is

approximately 9.3 nautical miles in

length and 3.6 nautical miles in width.

If a person or vessel has been granted

permission to enter the zone, they must

not enter waters within 1,000 yards of

the on scene Coast Guard vessel or test

equipment being used by Coast Guard

personnel.

The duration of the rule and

enforcement of the zone is intended to

protect personnel, vessels, and the

marine environment in these navigable

waters while the Coast Guard vessel and

test equipment are being used. All

vessels and persons must obtain

permission from the COTP Maryland-

National Capital Region or his

designated representative before

entering the security zone. Equipment

testing operations may occur anywhere

within the security zone during the

enforcement periods. Vessels and

persons will not be permitted to enter

the security zone within 1,000 yards of

the Coast Guard vessel or test

equipment. While this 1,000 yards area

lies within the security zone, its exact

location within the security zone may

change. The regulatory text we are

proposing appears at the end of this

document.

IV. Regulatory Analyses

We developed this proposed rule after

considering numerous statutes and

Executive orders related to rulemaking.

Below we summarize our analyses

based on a number of these statutes and

Executive orders, and we discuss First

Amendment rights of protestors.

A. Regulatory Planning and Review

Executive Orders 12866 and 13563

direct agencies to assess the costs and

benefits of available regulatory

alternatives and, if regulation is

necessary, to select regulatory

approaches that maximize net benefits.

This NPRM has not been designated a

‘‘significant regulatory action,’’ under

Executive Order 12866. Accordingly,

the NPRM has not been reviewed by the

Office of Management and Budget

(OMB).

This regulatory action determination

is based on location and duration of the

security zone. This security zone will be

enforced 182 hours over the course of a

two week period. Vessels will be able to

safely transit around the security zone,

which impacts a small area of the North

Atlantic Ocean, where vessel traffic is

normally low. Additionally, the Coast

Guard will make notifications to the

maritime community via marine

information broadcasts. The Coast

Guard will update such notifications as

necessary to keep the maritime

community informed of the status of the

security zone.

B. Impact on Small Entities

The Regulatory Flexibility Act of

1980, 5 U.S.C. 601–612, as amended,

requires Federal agencies to consider

the potential impact of regulations on

small entities during rulemaking. The

term ‘‘small entities’’ comprises small

businesses, not-for-profit organizations

that are independently owned and

operated and are not dominant in their

fields, and governmental jurisdictions

with populations of less than 50,000.

The Coast Guard certifies under 5 U.S.C.

605(b) that this proposed rule would not

have a significant economic impact on

a substantial number of small entities.

While some owners or operators of

vessels intending to transit the security

zone may be small entities, for the

reasons stated in section IV.A above,

this proposed rule would not have a

significant economic impact on any

vessel owner or operator.

If you think that your business,

organization, or governmental

jurisdiction qualifies as a small entity

and that this rule would have a

significant economic impact on it,

please submit a comment (see

ADDRESSES

) explaining why you think it

qualifies and how and to what degree

this rule would economically affect it.

Under section 213(a) of the Small

Business Regulatory Enforcement

Fairness Act of 1996 (Pub. L. 104–121),

we want to assist small entities in

understanding this proposed rule. If the

rule would affect your small business,

organization, or governmental

jurisdiction and you have questions

concerning its provisions or options for

compliance, please call or email the

person listed in the

FOR FURTHER

INFORMATION CONTACT

section. The Coast

Guard will not retaliate against small

entities that question or complain about

this proposed rule or any policy or

action of the Coast Guard.

C. Collection of Information

This proposed rule would not call for

a new collection of information under

the Paperwork Reduction Act of 1995

(44 U.S.C. 3501–3520).

D. Federalism and Indian Tribal

Governments

A rule has implications for federalism

under Executive Order 13132

(Federalism), if it has a substantial

direct effect on the States, on the

relationship between the National

Government and the States, or on the

distribution of power and

responsibilities among the various

levels of government. We have analyzed

this proposed rule under that Order and

have determined that it is consistent

with the fundamental federalism

principles and preemption requirements

described in Executive Order 13132.

Also, this proposed rule does not have

tribal implications under Executive

Order 13175 (Consultation and

Coordination with Indian Tribal

Governments) because it would not

have a substantial direct effect on one or

more Indian tribes, on the relationship

between the Federal Government and

Indian tribes, or on the distribution of

power and responsibilities between the

Federal Government and Indian tribes.

If you believe this proposed rule has

implications for federalism or Indian

tribes, please call or email the person

listed in the

FOR FURTHER INFORMATION

CONTACT

section.

E. Unfunded Mandates Reform Act

The Unfunded Mandates Reform Act

of 1995 (2 U.S.C. 1531–1538) requires

Federal agencies to assess the effects of

their discretionary regulatory actions. In

particular, the Act addresses actions

that may result in the expenditure by a

State, local, or tribal government, in the

aggregate, or by the private sector of

$100,000,000 (adjusted for inflation) or

more in any one year. Though this

proposed rule would not result in such

an expenditure, we do discuss the

effects of this rule elsewhere in this

preamble.

F. Environment

We have analyzed this proposed rule

under Department of Homeland

Security Directive 023–01, Rev. 1,

associated implementing instructions,

and Environmental Planning

COMDTINST 5090.1 (series), which

guide the Coast Guard in complying

with the National Environmental Policy

Act of 1969 (42 U.S.C. 4321–4370f), and

have made a preliminary determination

that this action is one of a category of

actions that do not individually or

cumulatively have a significant effect on

the human environment. This proposed

rule involves a security zone lasting

only 182 total enforcement hours that

will prohibit entry within a small

portion of the North Atlantic Ocean.

Normally such actions are categorically

excluded from further review under

paragraph L60(a) of Appendix A, Table

1 of DHS Instruction Manual 023–01–

001–01, Rev. 1. A preliminary Record of

Environmental Consideration

supporting this determination is

available in the docket. For instructions

on locating the docket, see the

ADDRESSES

section of this preamble. We

seek any comments or information that

may lead to the discovery of a

significant environmental impact from

this proposed rule.

G. Protest Activities

The Coast Guard respects the First

Amendment rights of protesters.

Protesters are asked to call or email the

person listed in the

FOR FURTHER

INFORMATION CONTACT

section to

coordinate protest activities so that your

message can be received without

jeopardizing the safety or security of

people, places, or vessels.

V. Public Participation and Request for

We view public participation as

essential to effective rulemaking, and

will consider all comments and material

received during the comment period.

Your comment can help shape the

outcome of this rulemaking. If you

August 8, 2014 (‘‘2014 FIP’’).

The

provisions of the 1991 action are

codified in the Code of Federal

Regulations (CFR) at 40 CFR 52.145(d),

the provisions of the 2010 action are

codified at 40 CFR 49.5513(a) through

(i), and provisions of the 2014 action are

codified at 40 CFR 49.5513(j). We refer

collectively to the provisions from the

1991, 2010, and 2014 actions as the

‘‘FIP’’ or the ‘‘NGS FIP.’’ The NGS FIP

includes federally enforceable emissions

limitations that apply to the fossil fuel-

fired steam generating equipment,

designated as Units 1, 2, and 3,

equipment associated with the coal and

ash handling, and the two auxiliary

steam boilers at NGS. These emissions

limitations apply to emissions of

particulate matter (PM), sulfur dioxide

(SO

), and oxides of nitrogen (NO

), and

opacity. The EPA is proposing to

rescind the NGS FIP and remove the

provisions of the FIP from 40 CFR

52.145(d) and 40 CFR 49.5513.

B. Facility

NGS was a coal-fired power plant that

ceased operation in 2019, located on the

reservation lands of the Navajo Nation,

just east of Page, Arizona, and

approximately 135 miles north of

Flagstaff. NGS was co-owned by several

entities and operated by Salt River

Project Agricultural Improvement and

Power District (‘‘SRP’’).

The facility

operated three units, each with a

capacity of 750 megawatts (MW) net

generation, with a total capacity of 2250

MW. Operations at the facility produced

air pollutant emissions, including

emissions of SO

, NO

, and PM.

Existing pollution control equipment at

NGS included wet flue gas

desulfurization units for SO

and PM

removal, electrostatic precipitators for

PM removal, and low-NO

burners with

separated over-fire air to reduce NO

formation during the combustion

process. Had the facility not ceased

operations, the owner or operator of

NGS would have taken steps by

December 31, 2019 to reduce emissions
