14Criterion III.A also applies to Fuel Cycle 

Facilities. 

15High-consequence events for facilities licensed 

under 10 CFR part 70 are those that could seriously 

harm the worker or a member of the public in 

accordance with 10 CFR 70.61. The integrated 

safety analysis (ISA) conducted and maintained by 

the licensee or applicant of 10 CFR part 70 fuel 

cycle facilities identifies such hazards and the 

safety controls (10 CFR 70.62(c)) applied to meet 

the performance requirements in accordance with 

10 CFR 70.61(b) through (d). Fuel cycle facilities 

licensed under 10 CFR part 40 or certified under 10 

CFR part 76 have licensing basis documents that 

describe facility specific hazards, consequences, 

and those controls utilized to prevent or mitigate 

the consequences of such accidents. For these 

facilities, a high-consequence event would be a 

release that has the potential to cause acute 

radiological or chemical exposures to a worker or 

a member of the public similar to that defined in 

NUREG–1520, Revision 2, Appendix A to Chapter 

3, Section A.2, under ‘‘Consequence Category 3 

(High Consequences)’’ (see http://www.nrc.gov/

16Criteria III.A.2, III.A.3, and III.A.4 also apply to 

medical licensees. 

(generic incidents) that raise a major safety 

concern. 

B. Fuel Cycle Facilities 14

1. Absence or failure of all safety controls 

(engineered and human) such that conditions 

were present for the occurrence of a highconsequence event involving an NRCregulated hazard (radiological or chemical).15

2. An NRC-ordered safety-related or 

security-related immediate remedial action. 

C. Events Involving the Medical Use of 

Radioactive Materials in Patients or Human 

Research Subjects 16

1. A medical event, as defined in 10 CFR 

35.3045, which results in a dose that: 

(a) Is equal to or greater than 1 Gray (Gy) 

(100 rad) to a major portion of the bone 

marrow or to the lens of the eye; or equal or 

greater than 2.5 Gy (250 rad) to the gonads; 

or 

(b) exceeds, by 10 Gy (1,000 rad), the 

expected dose to any other organ or tissue 

from the administration defined in the 

written directive; and 

2. A medical event, as defined in 10 CFR 

35.3045, which involves: 

(a) A dose or dosage that is at least 50 

percent greater than that prescribed, or 

(b) a prescribed dose or dosage that 

(i) uses the wrong radiopharmaceutical or 

unsealed byproduct material; or 

(ii) is delivered by the wrong route of 

administration; or 

(iii) is delivered to the wrong treatment 

site; or 

(iv) is delivered by the wrong treatment 

mode; or 

(v) is from a leaking source or sources; or 

(vi) is delivered to the wrong individual or 

human research subject. 

Appendix B: Other Events of Interest 

This appendix discusses other events of 

interest that do not meet the AO criteria in 

Appendix A. The Commission may 

determine that events, other than AOs, may 

be of interest to Congress and the public and 

should be included in an appendix to the AO 

report as ‘‘Other Events of Interest.’’ Such 

events may include, but are not necessarily 

limited to, events that do not meet the AO 

criteria but that have been perceived by 

Congress or the public to be of high health 

and safety significance, have received 

significant media coverage, or have caused 

the NRC to increase its attention to or 

oversight of a program area, or a group of 

similar events that have resulted in licensed 

materials entering the public domain in an 

uncontrolled manner.

SUPPLEMENTARY INFORMATION: 

Authority for This Rulemaking 

The FAA’s authority to issue rules 

regarding aviation safety is found in 

Title 49 of the United States Code. 

Subtitle I, Section 106 describes the 

authority of the FAA Administrator. 

Subtitle VII, Aviation Programs, 

describes in more detail the scope of the 

agency’s authority. This rulemaking is 

promulgated under the authority 

described in Subtitle VII, Part A, 

Subpart I, Section 40103. Under that 

section, the FAA is charged with 

prescribing regulations to assign the use 

of the airspace necessary to ensure the 

safety of aircraft and the efficient use of 

airspace. This regulation is within the 

scope of that authority as it would 

restructure the restricted airspace at the 

Stennis Space Center, MS, to enhance 

aviation safety and accommodate 

essential NASA and Naval Special 

Warfare Command (NSWC) 

requirements.

Background 

On July 10, 2014, the FAA published 

in the Federal Register an NPRM 

proposing to redesignate and expand 

restricted area R–4403, Gainesville, MS, 

to support missions of the National 

Aeronautics and Space Administration 

(NASA) and the Naval Special Warfare 

Command (NSWC) (79 FR 39344). Eight 

comments were received; two 

commenters supported the proposal, 

four commenters posed limited 

concerns, and the remaining two 

commenters objected to the proposal. 

Subsequent to publication, both 

NASA and NSWC revised their airspace 

proposal by changing certain restricted 

area boundaries, eliminating some 

proposed activities and increasing the 

proposed times of use of the airspace. 

The changes are described in the next 

section, below. 

Since these changes to the proposal 

are significant, the FAA has determined 

it is necessary to reopen the comment 

period to provide additional 

opportunity for public comment. The 

FAA will dispose of all the comments 

to the NPRM and SNPRM when it issues 

its final determination on the proposal. 

Differences From NPRM 

The southern boundary of R–4403B 

and R–4403C is shifted slightly to the 

north to address a comment that the 

restricted areas were too close to 

Interstate I–10, which is used by some 

pilots as a visual flight reference. 

The NPRM proposed to establish R– 

4403C, extending from the surface up to 

but not including 6,000 feet MSL; and 

to establish R–4403D, with the same 

lateral boundaries as R–4403C, and 

extending above R–4403C from 6,000 

feet MSL up to 10,000 feet MSL. This 

SNPRM proposes to combine R–4403C 

and R–4403D into a single restricted 

area extending from the surface up to 

10,000 feet MSL. This combined area 

would be designated R–4403C and the 

formerly proposed designation ‘‘R– 

4403D’’ would not be used. 

The NPRM proposed the time of 

designation for restricted areas R– 

4403C, D, E and F as ‘‘Intermittent, 1800 

to 2400 local time, as activated by 

NOTAM at least 24 hours in advance; 

other times by NOTAM with air traffic 

control (ATC) approval.’’ The SNPRM 

would revise the time of designation for 

R–4403C, E and F to ‘‘Intermittent, 2000 

to 0500 local time, as activated by 

NOTAM at least 24 hours in advance; 

and 1800 to 2000 local time, November 

1 to March 1, as activated by NOTAM 

at least 24 hours in advance, not to 

exceed 20 days per year.’’ The new 

times would expand the basic time 

frame during which the restricted areas 

could be activated from six hours per 

day to nine hours per day. Further, it 

would add a provision allowing for 

additional activation during the hours 

1800 to 2000 local time between 

November 1 and March 1. However, use 

of the 1800 to 2000 time frame between 

November 1 and March 1 would be 

limited to a maximum of 20 days per 

year. The provision in the NPRM 

allowing for activation of R–4403C, E 

and F at ‘‘other times by NOTAM with 

ATC approval’’ is removed from 

consideration in this proposal. 

The NPRM proposed the use of R– 

4403E and F for delivery of air-toground munitions at a ground target by 

aircraft, including AC–130 gunships and 

armed helicopters. The NSWC 

determined that the area is too small to 

contain the weapons safety footprint, so 

R–4403E and F would only be used to 

contain air-to-ground firing of non-eyesafe lasers. Ground forces would use 

lasers that are eye-safe in R–4403E and 

F to signal military aircraft operating 

overhead. 

The southeastern-most point of the R– 

4403E boundary (where it intersects the 

Stennis International Airport Class D 

airspace boundary (at lat. 30°20′22′′ N., 

long. 89°31′43′′ W.) would be shifted 

northward by approximately 2.5 NM to 

intersect the Class D airspace area at lat. 

30°22′35′′ N., long. 89°32′06′′ W. The 

airspace south of the new line would 

become a part of R–4403C. 

The Proposal 

The FAA is proposing an amendment 

to 14 CFR part 73 to remove restricted 

area R–4403, Gainesville, MS, and 

redesignate and expand the airspace to 

consist of five subareas: R–4403A, B, C, 

E and F, Stennis Space Center, MS. The 

FAA is proposing this action at the 

request of NASA and the NSWC to 

confine activities that potentially 

present hazards to nonparticipating 

aircraft. The existing airspace is too 

small to fully contain NASA activities 

and the proposed expansion would also 

enable NSWC to conduct realistic 

Special Operations Force training. 

R–4403A and B would continue be 

used for NASA activities, such as rocket 

engine testing and untethered space 

vehicle propulsion system testing. The 

NSWC would use the proposed R– 

4403C, E and F for integrated Special 

Operations Forces training. The 

proposed restricted areas are described 

below. 

R–4403A would be used by NASA to 

test rocket engine technology. It would 

consist of that airspace within a 2.5 NM 

radius of lat. 30°21′51′′ N., long. 

89°35′39′′ W., centered on the rocket 

engine test complex. R–4403A would 

extend from the ground to 12,000 feet 

MSL. It would replace R–4403 with an 

expanded area to more fully contain 

rocket engine testing hazards. This area 

remains as proposed in the NPRM. 

R–4403B would be used by NASA for 

untethered autonomous space vehicle 

testing. The area would extend upward 

from the ground to 6,000 feet MSL. 

These vehicles are utilized to explore 

planets and asteroids. Testing of these 

vehicles involves potential hazards 

since failure of the vehicle, its 

propulsion system or propellant tanks 

can result in explosion of the vehicle. 

The propensity for this to occur is 

greater with these vehicles than with a 

standard aircraft because of the 

extremely volatile nature of the 

propellants and the poor aerodynamic 

characteristics of the vehicle during 

earth-based operation. Proposed R– 

4403B is designed to contain the flight 

profiles of these vehicles as well as any 

potential hazards to nonparticipating 

aircraft. Except for the slight adjustment 

of the southern boundary, as described 

mstockstill on DSK4VPTVN1PROD with PROPOSALS

Federal Register / Vol. 80, No. 158 / Monday, August 17, 2015 / Proposed Rules 49183 

above, this area remains as proposed in 

the NPRM. 

R–4403C would be used for Special 

Operations Forces Integration Training. 

The NPRM proposed R–4403C to extend 

from the ground to 6,000 feet MSL. This 

SNPRM would expand R–4403C to 

extend from the ground to 10,000 feet 

MSL, incorporating the airspace from 

6,000 feet MSL to 10,000 feet MSL, 

which was formerly proposed as R– 

4403D. The designation ‘‘R–4403D’’ will 

no longer be used. R–4403C would 

contain air-to-ground live-fire training 

for AC–130 gunships, armed helicopters 

and tilt-rotor (CV–22) aircraft and 

surface-to-surface weapons firing. R– 

4403C would contain two impact areas 

for air-to-ground munitions employment 

(up to 105mm), and air-to-ground noneye-safe laser firing. Ground forces 

would use lasers that are eye-safe to 

signal military aircraft operating 

overhead. Anticipated use of R–4403C is 

100–120 days per year. 

R–4403D designation is removed from 

the proposal as described above. 

R–4403E would also be used for 

Special Operations Forces Integration 

Training. It would extend upward from 

the ground to 10,000 feet MSL. It would 

contain a ground target to be used only 

for air-to-ground firing of non-eye safe 

lasers. The proposal in the NPRM to use 

this area for air-to-ground munitions 

delivery is eliminated. Ground forces 

would also use lasers that are eye-safe 

to signal military aircraft operating 

overhead. 

R–4403F would extend upward from 

4,000 feet MSL to 10,000 feet MSL. R– 

4403F would wrap around the northeast 

corner of R–4403E and would be used 

in conjunction with R–4403E. 

R–4403E and F would always be 

activated together for AC–130 air-toground firing of non-eye-safe lasers. The 

two areas could be activated separately 

from R–4403C, but typically would be 

used in conjunction with R–4403C. 

The proposed time of designation for 

R–4403A and R–4403B is ‘‘Intermittent, 

1000 to 0300 local time, as activated by 

NOTAM at least 24 hours in advance.’’ 

This time frame is the same as proposed 

in the NPRM. The proposed time of 

designation for R–4403C, E and F is 

‘‘Intermittent, 2000 to 0500 local time, 

as activated by NOTAM at least 24 

hours in advance; and 1800 to 2000 

local time, November 1 to March 1 (not 

to exceed 20 days per year).’’ The times 

for R–4403C, E and F are changed from 

those in the NPRM as explained in the 

‘‘Differences from NPRM’’ section, 

above. 

Note: The term ‘‘Intermittent’’ is used 

to indicate occasional, irregular, or 

changeable use periods. 

During periods when the restricted 

areas are not needed by the using 

agencies, the airspace would be 

returned to the controlling agency for 

access by other airspace users. 

A revised color chart depicting the 

proposed restricted areas will be posted 

on the www.regulations.gov Web site 

(search Docket No. FAA–2014–0370). 

Regulatory Notices and Analyses 

The FAA has determined that this 

proposed regulation only involves an 

established body of technical 

regulations for which frequent and 

routine amendments are necessary to 

keep them operationally current. 

Therefore, this proposed regulation: (1) 

Is not a ‘‘significant regulatory action’’ 

under Executive Order 12866; (2) is not 

a ‘‘significant rule’’ under Department of 

Transportation (DOT) Regulatory 

Policies and Procedures (44 FR 11034; 

February 26, 1979); and (3) does not 

warrant preparation of a regulatory 

evaluation as the anticipated impact is 

so minimal. 

Since this is a routine matter that will 

only affect air traffic procedures and air 

navigation, it is certified that this 

proposed rule, when promulgated, will 

not have a significant economic impact 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act. 

Environmental Review 

This proposal will be subject to an 

environmental analysis in accordance 

with FAA Order 1050.1E, 

‘‘Environmental Impacts: Policies and 

Procedures,’’ prior to any FAA final 

regulatory action.

I. Introduction 

On August 5, 2015, the Postal Service 

filed a petition pursuant to 39 CFR 

3050.11 requesting that the Commission 

initiate an informal rulemaking 

proceeding to consider changes to 

analytical principles relating to the 

Postal Service’s periodic reports.1

Proposal Seven is attached to the 

Petition and proposes an analytical 

method change relating to the avoided 

costs for Flats Sequencing System (FSS) 

workshare discounts. Petition at 1. 

This Petition was filed in response to 

Order No. 2472, which directed the 

Postal Service ‘‘to file a proposed 

methodology for determining the costs 

avoided for the Presorted FSS 

workshare discounts, as described in the 

body of [Order No. 2472], within 90 

days of the date of [Order No. 2472].’’ 2

II. Summary of Proposal 

Under Proposal Seven, the Postal 

Service seeks to address the avoided 

costs relating to FSS mail. Petition, 

Proposal Seven at 1. The Postal Service 

bifurcates Proposal Seven into the Mail 

Processing and the Delivery elements of 

the avoided costs for FSS workshare 

discounts. Id. 

A. Section One: Proposed Method for 

Calculating Mail Processing Cost 

Avoidances 

The Postal Service seeks to modify the 

modeling methodology used in the 

USPS–FY14–11 (Docket No. ACR2014) 

Standard Mail Flats Mail Processing 

Cost Model to estimate the mail 

processing cost avoidances of FSS 

presorted Standard Flats. Petition, 

Proposal Seven, Section One at 1. The 

Postal Service expands the Standard 

Mail Flats Mail Processing Cost Model 

to identify the unique characteristics 

and flows of FSS-prepared Standard 

Flats. Id. As part of Library Reference 

USPS–RM2015–16/1 filed with the 

Petition, the Postal Service provides 

three models supporting this section of 

Proposal Seven. Id. The Postal Service 

also proposes changes to the USPS– 

FY14–11 (Docket No. ACR2014) 

Periodicals Flats Mail Processing Cost 

Model. Id. at 4.3

There are nine modifications 

proposed by the Postal Service in 

Section One of Proposal Seven, all of 

which apply to the Standard Mail Flats 

Cost Model. Petition, Proposal Seven, 

Section One at 4. Two of the proposed 

modifications also apply to the 

Periodicals Model. Id. 

1. Revision of the Methodology Used To 

Estimate the Proportion of Flats 

Processed in Mechanized Incoming 

Secondary Operations (Modification 

One) 

The Postal Service presents a process 

to estimate the proportion of flat-shaped 

mail processed in mechanized incoming 

secondary operations. Id. at 4–8. 

Although over 98 percent of flats 

destinate in the service territories of 

plants that have mechanized equipment, 

certain facilities choose to perform the 

incoming secondary sortation manually 

for a variety of reasons, including low 

volume, service commitments, and
