3 Final Summary Report 1.1 INTRODUCTION The Middlebury State Airport, located on the outskirts of the Village of East Middlebury, Vermont, serves the general aviation market, caters primarily to single engine aircraft, and is home to J&M Aviation, the sole Fixed Based Operator (FBO) located on the airfield (see Exhibits 1.1 and 1.2). Middlebury is a town of 8,400 people (estimated 2007 population) in Addison County. Major industries in the county include dairy farming and Middlebury College, an exclusive liberal arts college of 2,450 undergraduate students. The Middlebury Airport is located approximately 30 miles south of the Burlington International Airport and 40 miles north of the Rutland State Airport. The airfield consists of a single paved runway (1-19), which is 50 feet wide and 2,500 feet in length, approximately 87,000 square feet of apron, nine hangars, a combine terminal and maintenance building, and a full length parallel taxiway (see Exhibit 1.3). The approaches to both runways are visual. URS Corporation (URS) reviewed the Master Plan Update (2003) for the Middlebury State Airport to determine the design parameters for the proposed runway extension. Current aircraft traffic is generally small single engine aircraft, which lead to the Master Plan Update selection of the Cessna 172 as the predominant aircraft (2001). Both Federal Aviation Administration (FAA) Form and the Master Plan Update cite aviation activity in calendar year 1999 at 35,000 operations with the Master Plan forecast for moderate growth to 37,500 operations for 2004 and 40,200 operations in Historically, Middlebury State Airport has been one of the busier general aviation airports in the Vermont State System and these numbers appear reasonable. The Master Plan Update noted that the existing runway was adequate for the based aircraft. The Airport generally conforms to Aircraft Reference Code (ARC) A-I standards; however, the Master Plan noted the following non-conforming conditions: TABLE 1: NON-CONFORMING CONDITIONS EXISTING CONDITIONS ARC A-1 STANDARD Runway Width 50 feet 60 feet RSA - Runway feet wide x 150 feet beyond threshold 120 feet wide x 240 feet beyond threshold RSA - Runway feet wide x 200 feet beyond threshold 120 feet wide x 240 feet beyond ROFA - Runway feet wide x 200 feet beyond threshold 250 feet wide x 240 feet beyond threshold Source: Master Plan Update (March 2003). 2.1 OBSTRUCTION REMOVAL, RSA, AND OFA ANALYSIS The existing 14 Code of Federal Regulations (CFR) Part 77 Approach Drawings in the Master Plan Update revealed the following: RUNWAY 1: There are at least eight obstructions within the approach to Runway 1 (Exhibit 2.1). The obstructions in the Runway 1 approach appear to consist of solitary or groups of trees. Based on an understanding of the Airport property line and limits of the existing avigation easements, at least seven of these trees can be removed (cut down).

4 Final Summary Report RUNWAY 19: The existing approach to Runway 19 was found to be clear (Exhibit 2.2). There are no obstructions on existing Airport property. RUNWAY TRANSITIONAL SURFACES: Based on a review of the 14 CFR Part 77 Surfaces Plan in the Master Plan Update, there is at least one hangar north of the existing terminal that protrudes into the Transitional Surface. RUNWAY HORIZONTAL AND CONICAL SURFACES: The 14 CFR Part 77 Imaginary Surfaces Plan in the Master Plan Update notes ground obstructions on the east side of the airfield. These ground obstructions are caused by the Green Mountains, which rise to a height of 2,000 feet MSL, approximately 1.6 miles east of the airfield. Also, the Master Plan Update revealed the following non-conforming Runway Safety Area (RSA) and Runway Object Free Area (OFA) conditions: RSA: Runway 1-19, which is included under ARC Design Group I, requires a RSA 120 feet wide (60 feet on either side of the runway centerline) and 240 feet in length beyond the runway threshold. The current RSA for Runway 1 is 120 feet in width, which meets standards, however, given the topography off the runway end and the presence of a wetland, the RSA is only 100 feet in length beyond the runway threshold. Therefore, the ALP lists the existing Runway 1 RSA as a non-conforming condition. OFA: FAA design standards require an OFA that is 250 feet wide and 240 feet beyond the runway end. As noted in the Master Plan Update, Runway 1 OFA is 250 feet in width; however it only extends 200 feet beyond the Runway 1 end due to existing obstructions (trees) OBSTRUCTION REMOVAL, RSA, AND OFA ALTERNATIVES To clear the existing obstructions to the Runway 1 14 CFR Part 77 surfaces and to provide a standard RSA and OFA for Runway 1, two alternatives were developed to determine the ideal location of the Runway 1 threshold. ALTERNATIVE 1: This alternative would relocate the Runway 1 threshold 140 feet in order to provide a RSA (120 feet by 240 feet) and OFA (250 feet by 240 feet) (see Exhibit 2.3). This alternative would not impact wetlands and, therefore, would not require wetland permitting [US Army Corps of Engineers (ACOE) or Conditional Use Determination (CUD)]; however, it will require obtaining additional easements to clear obstructions #8 and #9. ALTERNATIVE 2: This alternative would relocate the Runway 1 threshold 341 feet, which would provide a standard RSA (120 feet by 240 feet) and OFA (250 feet by 240 feet) and would clear all existing 14 CFR Part 77 obstructions off-airport property (Exhibit 2.4). This alternative would not impact wetlands or require additional easements. Middlebury State Airport April Runway 1-19 Extension Analysis

5 Final Summary Report 3.1 RUNWAY EXTENSION ANALYSIS The Master Plan Update recommended widening the existing runway from 50 feet to 60 feet and extending the runway from 2,500 feet to 3,700 feet. These parameters were selected based on the Master Plan Update forecast of the critical or design aircraft as aircraft in ARC B-I. Examples of aircraft in this ARC include: Beechcraft (King Air B-100, Baron), Cessna [Businessliner (402), Golden Eagle (421)], Mitsubishi (MU-2), Piper (Navajo, Cheyenne, Aerostar), and Rockwell (Turbo Commander). All of these aircraft are currently in use and are frequent visitors to airports in the Northeast. Many of these (or similar) aircraft are currently using the Middlebury Airport, albeit, under ideal weather conditions and at reduced weight. The FBO has indicated the larger aircraft often depart with less than a full load of fuel to reduce weight during takeoff. The Vermont Airport System Plan (VASP), which was prepared by SH&E in July 1973, designated the Middlebury State Airport as an economic development airport. Standards developed under this Plan recommended that economic development airports have a minimum length of 4,000 feet and width of 100 feet. The VASP was revised in September Middlebury State Airport is now classified as a Local Service Airport. The VASP recommends that Local Service Airports serve aircraft in ARC B-1, with minimum standards to include a runway 75 feet wide and 4,000 feet in length. Requirements for Small Airplanes with fewer than 10 Passenger Seats identified in FAA Advisory Circular 150/5325-4B (July 2005) indicate that runway length for aircraft in ARC B-1 should be between 3,100 and 3,700 feet. A length of 3,100 feet will handle approximately 95% of the aircraft feet in ARC B-1, while a runway length of 3,700 feet will handle 100% of the ARC B-I fleet. The Airport provides aeronautical services for businesses and visitors to the area, which includes the Middlebury College Campus. Based on the Master Plan Update and the VASP recommendations, the present runway length of 2,500 feet is inadequate for many aircraft operations, and does not serve the recommended role for the Airport. Both of these documents recommended widening and extending Runway RUNWAY EXTENSION ALTERNATIVES The alternatives were developed with the assumption that additional easements would not be obtained to clear obstructions (#8 and #9 cited above) within Runway 1 14 CFR Part 77 surfaces and that the Runway 1 threshold would then be relocated 341 feet at Station to provide for a standard RSA and OFA as well as clear 14 CFR Part 77 surfaces (see Exhibit 2.4). ALTERNATIVE 1: This alternative would relocate the Runway 19 threshold approximately 1,194 feet at a gradient of 0.00% (Exhibit 3.1). This alternative will require tree clearing on Airport property and acquisition of additional avigation easements to clear trees north of existing Airport property. This alternative will have a minor impact on area wetlands and will require ACOE and CUD permitting. With relocating the threshold 341 feet, the resultant runway length would be 3,359 feet.

6 Final Summary Report ALTERNATIVE 2: This alternative would relocate the Runway 19 threshold approximately 935 feet at a gradient of 0.2% (Exhibit 3.2). This alternative will require tree clearing on Airport property, but no acquisition of additional easements or wetland impacts. With relocating the threshold 341 feet, he resultant runway length would be 3,100 feet. ALTERNATIVE 3: This alternative would relocate the Runway 19 threshold approximately 1,050 feet at a gradient of 0.7% (Exhibit 3.3). This alternative will require clearing of on Airport obstructions, but will clear the trees north of the Airport property. This alternative should have not require ACOE permits but will require a CUD from the Agency of Natural Resources for temporary work within the wetland buffer areas. With relocating the threshold 341 feet, the resultant runway length would be 3,215 feet. ALTERNATIVE 4: This alternative would relocate the Runway 19 threshold approximately 1,535 feet at a gradient of 2% (Exhibit 3.4). The 2% gradient will be required to clear the obstructions off Airport property. Note that 2% is the maximum allowable gradient for aircraft in Design Groups I and II; however, FAA Advisory Circular 150/ indicates that minimum longitudinal grades are desirable. A 2% gradient will also result in a threshold elevation approximately 45 feet above the existing ground elevation. Clearing will still be required on Airport property. With relocating the threshold 341 feet, the resultant runway length would be 3,700 feet. ALTERNATIVE 5: This alternative takes Alternative 4 above and applies the use of Declared Distances (see Exhibit 3.5). This alternative would relocate the Runway 19 threshold approximately 1,535 feet at a gradient of 2%. This option will provide 3,900 linear feet of runway pavement. Initially, the Runway 1 threshold will be placed at Station to allow a 20:1 clear approach to the south. The Runway 19 threshold will be placed at Station to provide a 20:1 clear approach to the north. Both Runways 1 and 19 will be displaced as shown on Exhibit 3.5. Displacing the thresholds as shown will provide the following usable runway lengths: TABLE 2: RUNWAY LENGTH AVAILABLE (FEET) RUNWAY 1 RUNWAY 19 LANDING 3,700 3,300 TAKEOFF 3,900 3,900 The displaced thresholds could be removed after easements are acquired and the obstructions removed. The resultant runway will be 3,900 feet in length. 4.1 FAA COMMENTS At a meeting with Vermont Agency of Transportation (VTrans) in May 2006, the FAA responded stating that extending Runway 1-19 from its current length of 2,500 feet to 3,700 feet was not satisfactorily justified in the 2003 Master Plan. Page 4-2 of this document stated: it is recommended that the necessary studies for the extension be carried out at the end of the short-term period to verify that the current aircraft fleet and operations warrant such an extension. From this statement, the FAA indicated Middlebury State Airport April Runway 1-19 Extension Analysis

7 Final Summary Report that the forecasts provided in the Master Plan do not support this proposed runway extension. In order to justify this extension, the runway length acceptable for ARC B-1 aircraft needed to be identified as well as a verification of the number of operations. As a result, action items from this meeting included the installation of acoustical (REMS) counters for Runway 1-19 by VTrans staff and the acquisition of letters of support from the community AVIATION FORECASTS As a result of the acoustical data and letters of support received, forecasts were updated prior to the preparation of the Purpose and Need and Environmental Assessment. REMS data received for the month of July 2006 recorded 483 aircraft takeoffs, which prorate to 11,592 annual operations. This number correlates reasonably with an accepted forecasting formula (based aircraft x 259 = 12,423 annual operations). Table 3 summarizes the aviation forecasts developed in the Master Plan and includes the 2006 REMS data.

J&M Aviation, the FBO, verified that there were 48 aircraft, including jet and multi-engine piston aircraft such as the Fougere Magistere, Piper Aztec, Cessna Citation and Cessna 310 based at the Airport in This number of existing based aircraft compared well with the Fleet Mix Forecasts in the Master Plan (2003), which is included in Table 4. In addition to the aircraft currently based on the airfield, other multi-engine and jet aircraft operating at Middlebury State Airport include the Piper Navaho, Piper Aztec, Piper Cheyenne, Cessna 402, and Beechcraft Baron.

The existing Master Plan forecasted the annual traffic growth at approximately 1.5% annually over the twenty year plan. Air traffic operations at the neighboring Rutland State Airport have increased approximately 2% annually since the year TABLE 5: PREFERRED AVIATION FORECASTS ( ) Actual Forecast Based Aircraft Local Operations 28, Itinerant Operations 7, Operations 35,000 11, Forecast Operations (Method A) ,800 14,000 Forecast Operations (Method B) ,468 14,763 Preferred Forecasts ,000 14,200 Airport Reference Code A-1 B-1 B-1 B-1 Source: URS Corporation (2007). 1 Airport Master Plan Update (March 2003). Using the 2006 data, URS developed the Aviation Forecasts cited in the Table 5 using two separate methodologies. The first methodology assumes that aviation growth at the Airport will continue at 2% annually. The second methodology assumes that the forecasts will increase in direct proportion to the based aircraft times 259. Since the results of both forecasts are similar, we are recommending the preferred forecast, as shown in Table 5. Both forecast methodologies assumed that the existing runway dimensions remain constant. These forecasts were reviewed and accepted by VTrans in February Middlebury State Airport April Runway 1-19 Extension Analysis

9 Final Summary Report LETTERS OF SUPPORT Letters in support of the recommendation for a runway extension to 3,700 feet have been received from the local community and business leaders as well as from aviation users (see Appendix). While some of these letters are of a generic content that simply imply support for the Airport; however, note that at least three of these letters are from potential Airport users, who cannot operate on the airfield due to the short runway. These operators include Worth Mountain Capital Partners, who currently charter aircraft that require a 3,700 foot runway, Eastway Aviation, a jet aircraft charter firm that serves the East coast, and Heritage Flight in Burlington, which operates King Air and Citation Aircraft. Each of these firms is unable to operate out of the Middlebury State Airport due to the limited runway length. In addition, Middlebury is home to Middlebury College, an exclusive liberal arts college. Many of its students, faculty, and trustees have access to high performance aircraft that cannot operate on the existing runway. While it is impossible to quantify this traffic potential, there would be numerous other air traffic that would use this Airport if the runway were long enough. There are many airports serving resort areas in the North Country that have better facilities and lack the traffic that currently exists at the Middlebury State Airport. Some of these airports are listed in Table 6. It would appear reasonable to expect traffic at Middlebury to mirror traffic at Morrisville-Stowe within the five to ten year time frame following construction of an extension to 3,700 feet. TABLE 6: AIRPORT COMPARISON Airport Runway Width & Length ARC Operations Based Aircraft Caledonia County State 60 x 3300 B-I 2, Parlin Field 50 x 3450 B-1 2, Middlebury State 50 x 2500 B-I 11, Morrisville-Stowe State 75 x 3701 B-II 18, Mount Washington Regional 75 x 4001 B-II 7, Lake Placid Municipal 60 x 4200 B-II 20, Ticonderoga Municipal 60 x 4040 B-I/B-II 11, Source: FAA Airport Master Record Form (1/18/07). Based on the existing traffic, potential traffic, forecast data, and support from the community, there is adequate evidence of existing unmet demand for a longer runway at the Middlebury State Airport. Construction of an extension to 3,100 feet (minimum for ARC B-I aircraft) will allow for some of the additional traffic to use this runway; however, there is doubt that this length will be sufficient to service all potential users, whereas an extension to 3,700 feet has the support of all users. 5.1 CONCLUSION The FAA indicated that they would support a 3,200 foot runway as the maximum recommended length for the Middlebury State Airport, based on the existing aviation forecasts, while both VTrans and the Middlebury Airport Committee have endorsed the Preferred Alternative (refer back to Exhibit 3.5) Middlebury State Airport April Runway 1-19 Extension Analysis

10 Final Summary Report On June 1, 2007, URS forwarded a letter to Richard Doucette requesting that the Environmental Assessment continue as originally scoped for Runway 1-19 with an ultimate length of 3,700 feet. In an response, the FAA has concurred in this request; however, the FAA has concluded that at this time they are not obligating the FAA to commit funding a runway extension beyond 3,200 feet.
