  1. SPANDEX: ACS Cable System Project Presented by: Steve Gebert, ACS Director for PMO Sherrie Greenshields, NHTI Marko Radonich, CH2MHILL Dale Patrick, ACS OSP Manager

  2. Purpose of Briefing • Purpose: • Provide overview of project for permitting authorities and other interested agencies • Ensure all questions and requests for information are addressed so that project can proceed according to agencies’ satisfaction, and according to schedule

  3. Overview • Overview: • SPANDEX highlights and route overview • Key objectives of route selection and installation techniques • List of primary construction activities • Route specifics by area (walkthrough of route) • Critical Contractual Deadlines • Permits roll call • Questions and answers • Points of Contact

  4. SPANDEX: What it Brings to Alaska • $100M fiber-optic cable system linking Alaska to Lower 48 • Unique route – high emphasis on diversity from existing cables • Landing in Oregon – highly diverse from other AK cables • Huge capacity (bandwidth) • Initial capacity: Over 500,000 simultaneous calls • Max capacity: Over 33,000,000 simultaneous calls • 25-year service life • Cutting-edge technology • Target Service Date: December 31, 2008

  5. Overview of Marine Segments

  6. Overview of Main Terrestrial Segments Cable Station

  7. Key Objectives of Route Selection • Diversity from existing systems • Redundancy on terrestrial routes • Best marine and terrestrial conditions for landings • Maximum use of existing facilities, easements, RoW, developed areas • Maximum avoidance of heavy fishing, anchoring, and other sensitive areas

  8. Impact Mitigation Techniques • Expertise and Experience • Extreme diligence in selecting contractors with extensive experience—including AK cable projects (drawing on all lessons learned) • Marine segment burial depth • Spec is 1.2m burial depth in all areas of water depth less than 1500m • Extensive sonar survey to find route that best supports burial • Very slow ship speed (1-2 kts when pulling plow) • Horizontal Direction Drilling (HDD) • Extremely expensive but minimizes/eliminates impact on coastal areas – ACS feels its well worth the cost

  9. Impact Mitigation Techniques (cont.) • Construction Timing • Earliest possible construction where able to avoid impact on wetlands, bird nesting season, tourist season, etc. • Need your help with this—permits are critical path in schedule

  10. Primary AK Construction Activities • Marine segments • Anchorage to Nikiski • Homer to Oregon • Terrestrial segments (Outside Plant– OSP) • Anchorage • Nikiski to ACS N. Kenai Wire Center • Ninilchik to Homer • Homer • Landings – Bore (HDD) and Beach Manhole (BMH) • Anchorage • Nikiski • Homer (also Ocean Ground Bed – OGB) • Cable Stations • Homer

  11. Marine Schedule

  12. Marine Schedule (and key sensitive areas)

  13. Route Specifics -- Anchorage • HDD from ocean side of Coastal Wildlife Refuge to BMH • Minimal impact on wildlife • No closure of Coastal Trail • OSP route max use of easements/Row • Tesoro easement • Airport fence line • Along road in Kincaid • Rasp. Rd. • Cable Shelter at Rasp. and Sand Lake • Small hut • Collocated with ATT cell site

  14. Route Specifics -- Anchorage

  15. Anchorage HDD

  16. Route Specifics -- Nikiski • HDD from BMH to 6m water depth • BMH in Marathon Oil easement area • New build from BMH to existing ACS Wire Center • Max use of RoW and easements

  17. Nikiski HDD

  18. Route Specifics – Nikiski to Homer • New build from BMH to ACS N. Kenai Wire Center • Existing plant to Ninilchik • New build from Ninilchik to Homer • Max use of RoW, easements, aerial routes

  19. Route Specifics -- Homer • New Cable Station and Retail Store • OSP to BMH – RoW/Easements • HDD to beach headwall (buried) at high water mark • Trenched in to low water mark • OGB – located in Ohlson Ln.

  20. Typical OGB

  21. Homer HDD

  22. Critical Contractual Deadlines • Anchorage and Nikiski build complete: 8/19/08 • Nikiski to Homer build complete: 8/19/08 • Homer build complete: 8/19/08 • Homer to OR segment ready for testing: 9/18/08 • System ready for customers: 12/31/08 • Ready to start ASAP to minimize seasonal impacts • Permits are currently driving timeline • Greatly appreciate your support!

  23. Permits Roll Call • Any required permits that we have not yet applied for? • Any additional agencies that we should contact?

  24. Questions and Answers

  25. Points of Contact • Steve Gebert, ACS • 907.564.1244 • sgebert@acsalaska.com • Sherrie Greenshields, NHTI • 907.761.6057 • sgreenshields@nhtiusa.com • Marko Radonich, CH2MHILL • 907.646.0332 • marko.radonich@ch2m.com • Dale Patrick, ACS • 907.564.1582 • dale.patrick@acsalaska.com
