Proposed Amendment to Class B Airspace; Salt Lake City, UT

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: This action proposes to modify Salt Lake City, UT, Class B 
airspace to contain aircraft conducting Instrument Flight Rules (IFR) 
instrument approach procedures to Salt Lake City International Airport 
(SCL), Salt Lake City, UT. The FAA is taking this action to improve the 
flow of air traffic, enhance safety, and reduce the potential for 
midair collision, while accommodating the concerns of airspace users. 
Further, this effort supports the FAA's national airspace redesign goal 
of optimizing terminal and en route airspace to reduce aircraft delays 
and improve system capacity.

DATES: Comments must be received on or before October 24, 2011.

Background

    In 1989, the FAA issued a final rule establishing the Salt Lake 
City, UT, Terminal Control Area (54 FR 43786). As a result of the 
Airspace Reclassification final rule (56 FR 65638), which became 
effective in 1993, the terms ``terminal control area'' and ``airport 
radar service area'' were replaced by ``Class B airspace area'' and 
``Class C airspace area,'' respectively. The primary purpose of a Class 
B airspace area is to reduce the potential for midair collisions in the 
airspace surrounding airports with high-density air traffic operations 
by providing an area in which all aircraft are subject to certain 
operating rules and equipment requirements.
    The SLC Class B airspace area was last modified in 1995 (60 FR 
48350) using air traffic activity levels from the 1990s, and has not 
been modified since. In recent years, Salt Lake City has completed 
construction projects to modernize, enhance safety, and provide for 
increased capacity at SLC. These projects included the construction of 
a new Runway 16 R/34 L at SLC. The new west runway places departures 
closer to the Oquirrh Mountains southwest of SLC, and these departures 
need to climb to 10,000 feet to safely clear the terrain. This requires 
downwind traffic to level at 11,000 feet to remain above departures, 
which leaves the arrival aircraft outside the Class B airspace.
    Since the SLC Class B airspace area was established, SLC has 
experienced increased traffic levels, a considerably different fleet 
mix, and airport infrastructure improvements enabling simultaneous 
instrument approach procedures. For calendar year 2009, SLC documented 
328,508 total operations and was rated 24th among all Commercial 
Service Airports with 9,903,821 passenger enplanements. Under the 
current Class B airspace configuration, aircraft routinely enter, exit, 
and then reenter Class B airspace while flying published instrument 
approach procedures, which is contrary to FAA Orders. Modeling of 
existing traffic flows has shown that the proposed expanded Class B 
airspace would enhance safety by containing all instrument approach 
procedures, and associated traffic patterns, within the

[[Page 52906]]

confines of Class B airspace and better segregate IFR aircraft 
arriving/departing SLC and Visual Flight Rules (VFR) aircraft operating 
in the vicinity of the SLC Class B airspace area. The proposed Class B 
airspace modifications described in this NPRM are intended to address 
these issues.

Pre-NPRM Public Input

    In 2009, the FAA initiated action to form an Ad Hoc Committee to 
provide comments and recommendations regarding the planned 
modifications to the SLC Class B airspace area. Participants in the 
committee included representatives from National Business Aviation 
Association (NBAA), Aircraft Owners and Pilots Association (AOPA), 
Delta and Sky West Airlines, Soaring Society of America (SSA), Utah 
Hang Gliding and Paragliding Association, Utah General Aviation 
Association, local flight schools, and individuals impacted by SLC 
Class B airspace.
    The Ad Hoc Committee recommended several charting changes for the 
SLC VFR Flyway Chart in order to have fewer ``blue arrow'' routes. This 
would eliminate clutter and draw more attention to the safety issue 
associated with paraglider and hang glider activity located east of 
Interstate 15 (I-15) at Point of the Mountain. The Ad Hoc Committee 
agreed that one ``blue arrow'' would suggest a north-south route on the 
east side of the Salt Lake Valley; and at the south end, the arrow 
would bend around Point of the Mountain. This would encourage pilots to 
fly around the hang gliding/paragliding area. The arrow would recommend 
northbound at 6,500 feet and southbound at 7,500 feet.
    Additionally, the Ad Hoc Committee suggested a bold note warning 
aircraft of the potential for hang gliding/paragliding activity east of 
I-15 at Point of the Mountain. A second ``blue arrow'' would suggest a 
route between the Garfield Stack at the north end of the Oquirrh 
Mountains and Point of the Mountain. The committee also suggested 
placing a ``blue arrow'' south and west of Hill Air Force Base. Since 
the F-16 aircraft depart southwest from Hill Air Force Base and climb 
rapidly to 6,500 feet, it would be safer for VFR aircraft to be at or 
below 6,000 feet when transitioning through this area.
    The Ad Hoc Committee requested a high altitude VFR transition route 
over I-80 be published. The appropriate Air Traffic Control (ATC) 
frequency would be published with a suggested eastbound altitude of 
11,500 feet and westbound altitude of 10,500 feet. Salt Lake TRACON 
would prefer to have more flexibility with the VFR over flights, and 
added ``expect'' to the routing description to indicate flexibility in 
route or altitude assignment.
    As announced in the Federal Register (75 FR 73983), informal 
airspace meetings were held on January 26, 2011, at the Ogden 
Conference Room, Ogden Hinckley Airport Terminal; on February 1, 2011, 
at the Conference Room in the Executive Terminal, West Salt Lake City, 
UT; and on February 3, 2011, at the Utah Valley University Aviation 
Flight Center, Provo, UT. These meetings provided interested airspace 
users with an opportunity to present their views and offer suggestions 
regarding the planned modification of the SLC Class B airspace. All 
comments received as a result of the informal airspace meetings, along 
with the recommendations made by the Ad Hoc Committee, were considered 
in developing this proposal.

Informal Airspace Meeting Comments

    Numerous commenters representing the glider community expressed 
concern with the proposed floor of area L. The glider pilots requested 
that the floor of proposed area L be raised to 10,500 feet to allow 
safer glider operations below Class B airspace along the ridgeline of 
the Wasatch Mountains.
    One commenter, not associated with the glider community and 
regularly transitions through this area, stated that it was unsafe for 
him to cross the ridgeline of the Wasatch Mountains below the proposed 
Class B floor of 10,000 feet.
    After review of the flight tracks through proposed Area L, the FAA 
agrees that the floor of Class B airspace can be raised to 10,500 feet 
in this area and still safely contain instrument procedures.
    One commenter requested that the ceiling of Class B airspace remain 
at 10,000 feet along the eastern edge of Area B over and east of U.S. 
Highway 89 to allow hang glider operations to remain at 10,000 feet and 
fly over the strong canyon winds associated with Weber Canyon.
    The FAA does not agree. A review of Salt Lake City's flight tracks 
shows numerous departures below 12,000 feet in this area. A Class B 
ceiling of 10,000 feet would expose these departures to VFR aircraft 
transitioning through this area west of the Wasatch Mountains. In 
addition, keeping one portion of the Class B airspace at 10,000 feet 
would necessitate adding a new area to the proposed airspace. Designing 
the Class B airspace with multiple ceiling altitudes increases the 
complexity of the airspace design, especially when it is only used in 
one small area. In the interest of reduced complexity, the Class B 
airspace should keep a consistent ceiling altitude of 12,000 feet.
    One commenter requested that the floor of Area E be raised to 7,000 
feet. The commenter stated that there is terrain in the area that is 
difficult to pass over below 6,500 feet, and that there is no logical 
reason for the air carriers to pass over this area below 7,500 feet.
    The FAA does not agree. After conducting a thorough review of Area 
E, the FAA determined that raising the floor of Class B airspace to 
7,000 feet does not safely contain Salt Lake City departure and arrival 
traffic.
    One commenter requested the identification of some visual reporting 
points to help identify Class B airspace northwest of South Valley 
Regional Airport (U42).
    The FAA was able to locate landmarks to identify the boundary 
between the proposed Class B surface area (Area A) and Area E, 
including the Usana Amphitheatre, the intersection of State Route 201 
and S. 8000 West St., and Interstate 15 (I-15). The western boundary is 
located over the foothills of the Oquirrh Mountains and there are no 
good ground references in this area. The FAA used the Wasatch VOR (TCH) 
12-mile DME arc to define the Area E boundary northwest of U42, arcing 
northwest until intercepting the Union Pacific railroad, then following 
the railroad westbound. Other than the western boundary of Area E due 
west of U42, Class B airspace should be easy to identify using 
landmarks and DME.
    Two commenters were concerned with the airspace around Point of the 
Mountain. One commenter requested that the Class B airspace over 
restricted area R-6412 be raised to 8,100 feet to avoid congestion east 
of R-6412 and Point of the Mountain. The other commenter stated that 
VFR aircraft are already funneled into a narrow space and that the new 
proposal will only make the situation worse.
    The FAA does not agree. The airspace around Point of the Mountain 
is a congested area. The finals for runways 34R and 35 at SLC pass 
approximately one mile west of Point of the Mountain. Aircraft on final 
for runway 34L are at, or descending to, 8,000 feet in this area, and 
why the 8,000-foot floor is proposed for Area G. With the current Class 
B design, the floor of Class B airspace is 9,000 feet to the south/
southwest of Point of the Mountain and 7,000 feet to the west/
northwest. The proposal does lower the Class B airspace west/southwest 
of the Point of the Mountain area from 9,000 feet to 8,000 feet, but 
raises the floor of Class B airspace south

[[Page 52907]]

of Point of the Mountain from 9,000 feet to 10,000 feet, and the 
airspace to the west/northwest from 7,000 feet to 8,000 feet. The 
proposed design allows north-and south-bound VFR aircraft along I-15 
and Point of the Mountain to remain 1,000 feet higher, at all times, 
than the present Class B design allows.
    AOPA and three individuals objected to the east to west 
transitioning through the proposed Class B airspace and one individual 
requested the FAA establish a VFR corridor. AOPA also requested 
published recommended altitudes, frequencies, and route of flight on 
the Salt Lake City VFR Flyway chart.
    The FAA does not agree. Salt Lake City's traffic flows and 
altitudes make an established VFR corridor impractical. Salt Lake City 
has only one downwind leg that passes west of the airport, and 
approximately 50 percent of Salt Lake City's traffic also departs to 
the west. These departures would conflict with any VFR corridor design 
that passed over the airport. As recommended by AOPA and the Ad Hoc 
Committee, Salt Lake City will publish frequencies, altitudes, and 
routes on the VFR Flyway chart to mitigate impacts to VFR aircraft. VFR 
aircraft, in contact with air traffic controllers, will continue to be 
able to transition through Class B airspace after receiving a 
clearance.
    One commenter stated that with parachute jump operations at the 
Ogden airport (OGD), there would be delays in receiving approval for a 
jump through Class B airspace and delays for the jump aircraft climbing 
or descending through the proposed Area N.
    The FAA does not agree. The parachute operation currently requests 
permission to jump in this area and the request is approved or denied 
based on traffic below the jump aircraft. If Area N is added to the 
Class B airspace as proposed, there would be no change to the current 
procedures. The jump aircraft can receive a Class B clearance at the 
same time the jumpers receive permission for the jump, and there will 
be no increased delay for the jump aircraft.
    One commenter questioned why it is necessary to have the floor of 
Class B airspace at 9,000 feet in Area H, especially in the southern 
portion.
    When Salt Lake City is in a north flow, IFR arrival traffic is 
regularly at 9,000 feet in this area when aircraft are on downwind, 
base, and final during their approaches. The VFR transition routes 
referenced are departure and arrival routes for VFR aircraft operating 
to and from Salt Lake City International Airport. These routes are 
contained within the Class B surface area. They cross the arrival end 
of the runways, then pass under the downwind westbound. A modification 
of Class B airspace in these areas is not possible. These VFR routes 
exist to benefit VFR aircraft and are designed to provide a shorter 
route to the west. If a pilot does not want to use these routes, he or 
she can always choose to avoid crossing over the water and depart north 
or south along I-15 enroute to the west practice area.
    One commenter stated that local law enforcement has a tracking 
program that currently operates over the top of Class B airspace at 
10,500 feet and that it would make it difficult or impossible to 
continue the tracking program above 12,000 feet. The individual also 
contends that the sensitivity of the equipment does not allow two-way 
radio communication.
    The FAA does not agree. Salt Lake City Tower and Approach control 
has numerous Letters of Agreement with local law enforcement and 
welcomes discussions about creating a new Letter of Agreement to 
support the telemetry-tracking program. The area in which these 
operations occur has numerous aircraft climbing and descending through 
10,500 feet, which reinforces the need for the raised ceiling of class 
B airspace.
    One commenter argued that the Mode C veil has greatly reduced 
general aviation at Cedar Valley Airport (UT10).
    The FAA does not agree. UT10 is located approximately 26 miles 
south of Salt Lake City International and is within the 30 mile Mode C 
veil. The current Class B design has a floor of 9,000 feet, as does the 
proposed design. The UT10 elevation is approximately 5,000 feet and 
should be easily accessible below the 9,000 foot Class B shelf, without 
requiring a Class B clearance. The proposed Class B airspace design, 
and the current Mode C veil, do not limit any aircraft operations at 
UT10 below 9,000 feet.
    Two commenters proposed splitting the proposed Area O into two 
sectors, north and south, with a 6,500 feet area to the north and a 
7,000 feet area to the south. The individuals are concerned about 
commercial aircraft in a continuous flow over their houses.
    The FAA does not agree. FAA Order 7400.2 provides that Class B 
airspace is to be designed to contain all instrument procedures. At the 
southern edge of proposed Area O, there are two fixes on the runway 34L 
and 34R ILS approaches, DUNLP and SCOER. After arrivals cross these two 
fixes, they descend to 6,100 feet to meet the next crossing restriction 
on the arrival. The instrument approaches IFR aircraft are flying will 
not change and raising the floor of Class B airspace above 6,000 feet 
in this area will not contain these two instrument procedures as 
required.
    AOPA contends that raising the ceiling of Class B airspace to 
12,000 feet provides no clear operational safety benefits for any 
specific user, but will have a detrimental impact on general aviation 
safety and efficiency.
    The FAA does not agree. There are approximately 1,000 IFR 
operations a day that operate at and below 12,000 feet within 30 miles 
of SLC. The Ad Hoc Committee extensively discussed raising the ceiling 
to 12,000 feet and a consensus of that group supported the change. The 
general aviation members of the committee endorsed raising the ceiling 
to 12,000 feet, and they are the group most familiar with VFR flight in 
the area.
    It should be noted that FAA Order 7400.2 provides that, ``The outer 
limits of the airspace shall not exceed a 30-nautical mile (NM) radius 
from the primary airport. This 30-NM radius generally will be divided 
into three concentric circles. The floor of the area between 20 NM and 
30 NM shall be at an altitude consistent with approach control arrival 
and departure procedures. It is expected that this floor would normally 
be between 5,000 and 6,000 feet above airport elevation.'' Using this 
criterion, the floor of the Salt Lake City Class B airspace between 20 
and 30 miles should be between 9,227 feet and 10,227 feet. Presently 
the ceiling of the Salt Lake City Class B airspace is 10,000 feet, and 
does not contain existing arrival and departure procedures as required. 
Of the 30 airports with Class B airspace in the United States, SLC has 
the second highest field elevation. The current height of Salt Lake 
City Class B airspace rises 5,773 feet above ground level, the lowest 
of any in the nation. With the requirement to climb departures to 
10,000 feet, this leaves ATC with no available altitudes to contain 
downwind arrivals in Class B airspace. An increase to 12,000 feet would 
increase the Class B airspace to 7,773 feet above ground level, which 
is still lower than the national average of 8,373 feet.
    Commenters from the Soaring Society of America (SSA) stated that 
the vertical extension would require more IFR traffic to exit the side 
of controlled airspace and that the FAA should mandate that all IFR 
aircraft enter and exit through the top of Class B airspace, 
referencing FAA Order 7210.3, section 11-1-5. This section states that 
arrivals and departures should enter and exit the top of Class B 
airspace, not shall enter and exit through the top of Class B airspace. 
A further examination of FAA

[[Page 52908]]

Order 7210.3 defines the terms ``should'' and ``shall''. Shall 
indicates a procedure is mandatory, should indicates a procedure is 
recommended.
    FAA Order 7210.3, section 11-1-5 also states that, ``* * * each 
Class B airspace shall reflect the most efficient and reasonable 
configuration to contain large turbine powered aircraft while achieving 
a higher level of safety.'' A further examination of the arrival 
traffic on January 1, 2011, showed that of the 119 arrivals that were 
at or below 12,000 feet, 74 were large turbine-powered aircraft, or 21 
percent.
    Commenters from the SSA also stated that even a modest increase in 
the ceiling height of the SLC Class B airspace will result in a 
reduction in the number of sailplane flights that are able to 
transition above the Class B airspace.
    The FAA analyzed actual Salt Lake City arrival and departure tracks 
for July 16, 2010, as it was the hottest day of 2010 at 102 degrees. 
The FAA selected that date since aircraft climb slower on hot days and 
this would represent the worst-case departure scenario. Of the 510 
departures on that day, 31 departures exited the side of the proposed 
Class B airspace, which is 6 percent of all departures. The FAA also 
analyzed January 1, 2011, which was the coldest winter day in 2010/2011 
with an average daily temperature of 37.2 degrees. Of the 354 arrivals 
on that day, 119 arrivals were at or below 12,000 feet before they were 
contained in the lateral confines of the proposed SLC Class B airspace, 
which is 32 percent of all arrivals.
    Raising the ceiling of Class B airspace to 12,000 feet means that 
83 percent of all IFR operations, including large turbine powered and 
smaller aircraft will depart and arrive through the ceiling of Class B 
airspace. Raising the ceiling to 12,000 feet is the most efficient and 
reasonable configuration for Salt Lake's Class B airspace.

The Proposal

    The FAA is proposing an amendment to Title 14 of the Code of 
Federal Regulations (14 CFR) part 71 to modify the SLC Class B airspace 
area. This action (depicted on the attached chart) would raise the 
existing ceiling from 10,000 feet to 12,000 feet in order to provide 
additional airspace that is needed to contain aircraft conducting 
instrument approach operations within the confines of Class B airspace. 
Additionally, the proposed modifications would better segregate IFR 
aircraft arriving/departing SLC and VFR aircraft operating in the 
vicinity of the Salt Lake Class B airspace area. The proposed 
modifications to the SLC Class B airspace area are:
    Area A. Area A would be redefined from the surface to 12,000 feet. 
The northern boundary would be moved south an average of 2 miles. This 
would allow VFR aircraft to transition westbound sooner than is 
currently available and will relieve some congestion between the Hill 
Air Force Base (AFB) Class D airspace and Salt Lake City's Class B 
surface area airspace. As recommended by the Ad Hoc Committee, the 
surface area north of the Skypark Airport (BTF) would move to the west 
to relieve congestion between the Class B surface area airspace and the 
Wasatch Mountains to the east. Also, the surface area east of South 
Valley Regional Airport (U42) would be removed and combined with the 
6,000-foot shelf over and to the southeast of U42. IFR arrivals and 
departures at Salt Lake airport are above 6,100 feet in this area and 
would be contained by a 6,000-foot shelf (see Area D).
    Area B. Area B would incorporate portions of existing Areas B and 
J, with a floor at 7,800 feet and the ceiling raised to 12,000 feet. 
The western boundary would change from the I-BNT 25-mile DME arc to the 
TCH 20-mile DME arc. Raising the floor of existing Area B from 7,600 
feet to 7,800 feet matches the existing Class B airspace area over Hill 
AFB, and allows VFR aircraft operating in the area to climb sooner than 
is currently possible.
    Area C. Area C would be a new area in existing Class B airspace, 
with the ceiling raised to 12,000 feet, to reduce congestion in the 
airspace between the Hill AFB Class D airspace area and the SLC Class B 
surface area airspace. This area would incorporate a portion of 
existing Area A, with the floor raised from the surface to 6,000 feet, 
to allow VFR aircraft easier access to transit north of SLC below the 
Class B airspace area.
    Area D. Area D would remain similar to the existing Area D; 
expanded laterally into existing Class B airspace with the ceiling 
raised to 12,000 feet. This area would incorporate a portion of 
existing Area A, raising the floor from the surface to 6,000 feet, to 
allow VFR aircraft easier access to and from U42. The southern boundary 
would ensure aircraft are fully contained within Class B airspace while 
flying Instrument Landing System (ILS) approaches to runways 34L and 
34R.
    The Salt Lake Valley has several areas along the west side where 
the terrain penetrates the floor of existing Class B airspace, making 
the airspace in those areas unuseable by IFR traffic. As such, the 
western boundary of the Class B airspace in those areas could be moved 
to the east without compromising flight safety. The following 
descriptions of proposed areas E, F, G and H reflect this boundary 
shift to the east. Since there are not convenient visual landmarks in 
this area, the western boundaries of the proposed Class B airspace sub-
areas are best defined using longitude 112[deg]07'00'' W.
    Area E. Area E would combine two existing Class B airspace sub-
areas (Areas C and K) into one with the floor established at 6,500 feet 
and the ceiling raised to 12,000 feet. The southern boundary would 
extend south slightly using the TCH 16-mile DME arc. The southwest 
portion of Class B airspace boundary would be relocated east slightly 
using the TCH 12-mile DME arc to eliminate terrain penetrating the 
floor of Class B airspace. The western boundary defined by the TCH 
13.5-mile DME arc instead of the I-BNT 13-mile DME arc, to the to 
contain IFR departures.
    Area F. Area F would be a new area in existing Class B airspace 
(Area E), with the ceiling raised to 12,000 feet and the northern 
boundary defined by the TCH 16-mile DME arc instead of the I-BNT 11 DME 
arc. The southern boundary would move south slightly to fully contain 
the runway 34L and 34R ILS approaches.
    Area G. Area G would combine the current Areas F and G into one 
with the floor established at 8,000 feet and the ceiling raised to 
12,000 feet. The southern boundary would be established approximately 
four miles south of the existing southern boundary of existing Areas F 
and G to allow IFR traffic during Simultaneous Independent ILS 
approaches to join final closer to the airport and improve efficiency. 
The terrain in this area is mostly below 7,000 feet and shouldn't 
restrict VFR aircraft from climbing south bound below the Class B 
airspace area.
    Area H. Area H would remain similar to the current Area H with the 
floor at 9,000 feet, but the ceiling raised to 12,000 feet. This area 
would also expand slightly to the west to use the same longitude for 
its boundary as is used in Area G description, for simplicity, and 
would redefine the southern boundary further north by using the TCH VOR 
33 DME arc.
    Area I. Area I would be a new area east of area H, with a floor of 
10,000 feet and a ceiling of 12,000 feet, designed to capture arrivals 
from the southeast. This would be a commonly used corridor for north 
arrivals, and would aid air traffic control in sequencing.

    Area J. Area J would be a new area over the north end of the 
Oquirrh Mountains with the floor established at 11,000 feet and the 
ceiling at 12,000 feet. This area would contain IFR departure traffic 
climbing southbound, as well as contain arrival traffic being vectored 
to the downwind.
    Area K. Area K would be a new area redefining a portion of the 
current Area B. This area would raise the floor of Class B airspace to 
8,600 feet and raise the ceiling to 12,000 feet to provide more 
altitudes for VFR aircraft.
    Area L. Area L would redefine a portion of the current Area I to 
allow for north-flow departures from SLC to climb and turn eastbound on 
course. Area L would be established with a floor raised to 10,500 feet 
and the ceiling raised to 12,000 feet. Currently, there are two 
geographically separate airspace areas, 9,000 feet to 10,000 feet, that 
collectively comprise area I. One area is located northeast of SLC 
Airport, and the other area is located to the southeast. Both of these 
existing Class B airspace areas have terrain that penetrates the floor 
of the areas, with the southeastern area actually having terrain that 
extends through the ceiling of the area as well. Since the southern 
portion of existing Area I is only occasionally used for IFR aircraft, 
and is almost never used for large turbo jet aircraft, this portion of 
Area I would be deleted completely without impact to flight safety. 
Additionally, the eastern boundary of this new area would be moved to 
the west along the ridgeline of the Wasatch Mountains and still contain 
IFR departures turning eastbound.
    Area M. Area M would remain similar to the existing Area M, with 
the floor lowered to 9,000 feet and the ceiling raised to 12,000 feet. 
The lateral boundaries would extend slightly with the northern boundary 
extended north to the TCH 26-mile DME arc and the western boundary 
extended west one mile to ensure the runway 16L/1R downwind is 
contained within Class B airspace during Simultaneous Independent ILS 
approaches.
    Area N. Area N would be a new area, with the floor established at 
10,000 feet and the ceiling at 12,000 feet, intended to contain 
aircraft flying instrument approaches to SLC runway 17. Runway 17 is 
used extensively, often designated as a main arrival or departure 
runway, in the various SLC runway use plans. Aircraft are regularly 
established on a runway 17 final 30 miles from the airport and 
descending through 12,000 feet in this area.
    Area O. Area O would be a new subarea description that would lower 
a portion of existing Class B airspace in this area from 7,600 feet to 
7,500 feet. Lowering the Class B airspace area floor in this area would 
allow aircraft flying the runway 16R and 16L ILS approaches to descend 
to 7,500 feet and provide containment for them throughout the 
instrument approach procedures. Area O would also incorporate airspace 
north and east of SLC, currently Area L.

Paperwork Reduction Act

    The Paperwork Reduction Act of 1995 (44 U.S.C. 3507(d)) requires 
that the FAA consider the impact of paperwork and other information 
collection burdens imposed on the public. We have determined that there 
is no new information collection requirement associated with this 
proposed rule.

Economic Summary

    Changes to Federal regulations must undergo several economic 
analyses. First, Executive Order 12866 and Executive Order 13563 direct 
that each Federal agency shall propose or adopt a regulation only upon 
a reasoned determination that the benefits of the intended regulation 
justify its costs. Second, the Regulatory Flexibility Act of 1980 (Pub. 
L. 96-354) requires agencies to analyze the economic impact of 
regulatory changes on small entities. Third, the Trade Agreements Act 
(Pub. L. 96-39) prohibits agencies from setting standards that create 
unnecessary obstacles to the foreign commerce of the United States. In 
developing U.S. standards, the Trade Act requires agencies to consider 
international standards and, where appropriate, that they be the basis 
of U.S. standards. Fourth, the Unfunded Mandates Reform Act of 1995 
(Pub. L. 104-4) requires agencies to prepare a written assessment of 
the costs, benefits, and other effects of proposed or final rules that 
include a Federal mandate likely to result in the expenditure by State, 
local, or tribal governments, in the aggregate, or by the private 
sector, of $100 million or more annually (adjusted for inflation with 
base year of 1995). This portion of the preamble summarizes the FAA's 
analysis of the economic impacts of this proposed rule.
    Department of Transportation Order DOT 2100.5 prescribes policies 
and procedures for simplification, analysis, and review of regulations. 
If the expected cost impact is so minimal that a proposed or final rule 
does not warrant a full evaluation, this Order permits that a statement 
to that effect and the basis for it to be included in the preamble if a 
full regulatory evaluation of the cost and benefits is not prepared. 
Such a determination has been made for this proposed rule. The 
reasoning for this determination follows:
    After consultation with a diverse cross-section of stakeholders 
that participated in the Ad Hoc Committee to develop the 
recommendations contained in this proposal, and a review of the 
recommendations and comments, the FAA expects that this proposed rule 
would result in minimal cost. The FAA is taking this action to improve 
the flow of air traffic, enhance safety, and reduce the potential for 
midair collision in the SLC Class B airspace.
    This NPRM would enhance safety, reduce the potential for a midair 
collision in the SLC area and would improve the flow of air traffic. As 
such, we estimate a minimal impact with substantial positive net 
benefits. The FAA requests comments with supporting justification about 
the FAA determination of minimal impact. FAA has, therefore, determined 
that this proposed rule is not a ``significant regulatory action'' as 
defined in section 3(f) of Executive Order 12866, and is not 
``significant'' as defined in DOT's Regulatory Policies and Procedures.

Regulatory Flexibility Determination

    The Regulatory Flexibility Act of 1980 (Pub. L. 96-354) (RFA) 
establishes ``as a principle of regulatory issuance that agencies shall 
endeavor, consistent with the objectives of the rule and of applicable 
statutes, to fit regulatory and informational requirements to the scale 
of the businesses, organizations, and governmental jurisdictions 
subject to regulation. To achieve this principle, agencies are required 
to solicit and consider flexible regulatory proposals and to explain 
the rationale for their actions to assure that such proposals are given 
serious consideration.'' The RFA covers a wide-range of small entities, 
including small businesses, not-for-profit organizations, and small 
governmental jurisdictions.
    Agencies must perform a review to determine whether a rule will 
have a significant economic impact on a substantial number of small 
entities. If the agency determines that it will, the agency must 
prepare a regulatory flexibility analysis as described in the RFA.
    However, if an agency determines that a rule is not expected to 
have a significant economic impact on a substantial number of small 
entities, section 605(b) of the RFA provides that the head of the 
agency may so certify and a regulatory flexibility analysis is not 
required. The certification must include a statement providing the 
factual basis for this determination, and the reasoning should be 
clear.

[[Page 52910]]

    The FAA believes the proposal would not have a significant economic 
impact on a substantial number of small entities as the economic impact 
is expected to be minimal. We request comments from the potentially 
affected small businesses. Therefore, the FAA certifies that this 
proposed rule would not have a significant economic impact on a 
substantial number of small entities.

International Trade Impact Assessment

    The Trade Agreements Act of 1979 (Pub. L. 96-39), as amended by the 
Uruguay Round Agreements Act (Pub. L. 103-465), prohibits Federal 
agencies from establishing standards or engaging in related activities 
that create unnecessary obstacles to the foreign commerce of the United 
States. Pursuant to these Acts, the establishment of standards is not 
considered an unnecessary obstacle to the foreign commerce of the 
United States, so long as the standard has a legitimate domestic 
objective, such the protection of safety, and does not operate in a 
manner that excludes imports that meet this objective. The statute also 
requires consideration of international standards and, where 
appropriate, that they be the basis for U.S. standards. The FAA has 
assessed the potential effect of this proposed rule and determined that 
it would enhance safety and is not considered an unnecessary obstacle 
to trade.

Unfunded Mandates Assessment

    Title II of the Unfunded Mandates Reform Act of 1995 (Pub. L. 104-
4) requires each Federal agency to prepare a written statement 
assessing the effects of any Federal mandate in a proposed or final 
agency rule that may result in an expenditure of $100 million or more 
(in 1995 dollars) in any one year by State, local, and tribal 
governments, in the aggregate, or by the private sector; such a mandate 
is deemed to be a ``significant regulatory action.'' The FAA currently 
uses an inflation-adjusted value of $140.8 million in lieu of $100 
million. This proposed rule does not contain such a mandate; therefore, 
the requirements of Title II of the Act do not apply.
