1 INTRODUCTION

Alaska Aerospace (AAC), a public corporation of the State of Alaska, was established by Alaska statute as the Alaska Aerospace Development Corporation (AADC) in 1991.

The Pacific Spaceport Complex – Alaska (PSCA), formerly known as the Kodiak Launch Complex, located at Narrow Cape, and operated by Alaska Aerospace, was the nation’s first commercial spaceport not collocated on a federal range.

PSCA is a spaceport licensed by the Federal Aviation Administration Commercial Space Transportation

(FAA/AST) under provisions of the Commercial Space Launch Act (CSLA) Title 51 U.S. Code Chapter 509) to provide orbital and suborbital launch capability.

PSCA is situated on 3,717 acres of state-owned land under an Interagency Land Management

Assignment (ILMA) with the Department of Natural Resources. Under this agreement, AAC can also restrict access to another 7,048 acres surrounding the launch complex to protect the general public from potential operational hazards associated with launch operations at PSCA (see attached map and

ADL 226285). PSCA is proposing to renew this lease for another 30 year term.

1.1 INTERAGENCY LAND MANAGEMENT ASSIGNMENT ADL 226285 DESCRIPTION

This ILMA includes the approximately 3,717 acres of land as approved on May 18, 1994, and amended on February 3, 2003. This revised ILMA request includes the 88 acres of US Coast Guard (USCG) lands already located within the PSCA ILMA area which would increase the total acreage to 3805. These areas are described as:

1.1.1 Core Launch Facility

Township 31 South, Range 19 West, Seward Meridian

All state lands within Sections 31, 32, 33, and 34; and

All state lands within the South ½ of Section 29 and South ½ of Section 30

Township 32 South, Range 19 West, Seward Meridian

All state lands within Sections 3, 4, 5, 6 and 9

This ILMA also includes the approximately 7,048 acres of Ugak Island, Pasagshak Point, and highlands to the north and west of PSCA as safety areas during periods of hazardous and launch operations and does not include the Core Permit Area, as described in the amended ILMA dated October 20, 2008. These lands, along with the original ILMA approved lands, are depicted on the Figure 1 map, and are further described as:

1.1.2 Narrow Cape Safety Zone

State lands to the north and west of the Core Permit Area as defined by the April 19, 2005, ILMA.

Containing approximately 5,581 acres.

Township 32 South, Range 20 West, Seward Meridian

All state lands within Sections 1, 2, 3, 4, plus 9 and 10.

Township 31 South, Range 20 West, Seward Meridian

All state lands within Sections 25 and 34, 35, 36

Township 31 South, Range 19 West, Seward Meridian

All state lands within the South ½ of Sections 19, 20, 21, 22, plus 27 and 28, and the North ½ of

Sections 29 and 30.

1.1.3 Ugak Island Safety Area

All state lands comprise Ugak Island to the south of the Core Permit Area. Containing approximately

1,467 acres.

Township 32 South, Range 19 West, Seward Meridian

All state lands within Sections 23, 24, 25, 26, 27, plus 34 and 35.

1.1.4 Non-Development Areas

These areas marked by the purple borders will be designated as non-development areas. The Narrow Cape area south of Twin Lakes and the established launch areas at PSCA has been recognized as an area of high importance to maintain a natural state, undeveloped, and available for public use. The area will be retained to preclude potential development and/or conflicting uses being created by other agencies or entities.

FIGURE 1: CORE LAUNCH FACILITY & SAFETY ZONE MAP

Core Launch Facility

Narrow Cape & Ugak Island Safety Zone - Public access will be blocked in these areas during hazardous operations.

Kodiak Narrow Cape Public Use Area

Road access will not be permitted past the red point during launches, and the yellow, green, and blue points during testing.

This is further discussed in Section 2.

FIGURE 2: NON-DEVELOPMENTAL AREAS

Areas outlined in Purple will be designated as Non-Development Areas

2 PUBLIC USE AND PUBLIC ROAD CLOSURES

Current public use of the core launch facility and the safety zone land includes the following activities:

- Hiking

- Use of the beaches

- Berry picking/foraging

- Fishing

- Animal watching

Land closures are needed to protect the public from hazardous operations from launching, testing, and chemicals. PSCA’s legally required closure distance is determined by calculating explosive quantity distances established by the Federal Aviation Administration (FAA) by evaluating the amount of the chemicals used on an asset and the type of activity. Closure durations are also based on the type of activity and may range from four to nine hours a day. AAC coordinates closures with the Department of Natural Resources, the Department of Transportation, the Federal Aviation Administration, and the US Coast Guard to ensure all national, regional, and local laws, ordinances, regulations, and other applicable requirements are met. Closures are then communicated to the public by radio, road signs, notices to airmen and mariners, and website updates.

Launches:

Currently, AAC is authorized to have 9 launches per year, although AAC is seeking to increase this number in the near future. During launches, the road will be closed in coordination with the Department of Transportation and Department of Natural Resources at Pasagshak Road, Mile Post (MP) 10, as demonstrated by the red dot in Figure 1. Both the core launch facility and the safety zone would be closed and patrolled to prevent unauthorized entry. The nearby airspace and waterways are closed in coordination with the Federal Aviation Administration and the US Coast Guard.

Testing:

Occasionally AAC will need to host customers that need to conduct rocket testing. In this case, the road will be closed at Spaceport Entrance, Burton Blvd., and/or fossil beach, represented by the yellow, green and blue dot, in coordination with the Department of Natural Resources and the Department of Transportation if necessary. The exact location of the closure is dependent on PSCA legal closure requirements, the launch vehicle type and degree of hazard for the test being conducted. Only core launch facility lands will be closed for these operations.
