INVITATION FOR MULTI-STEP RE-BID NO.: GPA-066-13

FOR

WIND TURBINE PILOT PROJECT DESIGN AND CONSTRUCTION

Prospective Bidders are hereby notified of the following response to inquiries received from AM Orient Engineering dated October 25, 2013 and Olleh Corporation dated November 08, 2013: AM Orient Engineering dated October 25, 2013: QUESTION:

1. Thank you for taking the time to listen to our concern about the specification for the wind turbine. During the bidders conference, GPA engineer said that the specifications of the wind turbine count not be changed because if we proposed a different wind turbine the NEPA documentation would have to be resubmitted and this would delay the project start. After an extensive research, it appears that the only manufacturer that exactly meets the current specification is Vergnet from France. We have contacted other manufactures that have similar specifications but they don’t match exactly the requested specification. Based on the above, we would like to get a copy of the submitted NEPA to better understand the RFP. Also, could you indicate if GPA would welcome proposals that propose wind turbines with similar but not identical parameters.

Dear Dr. Mehrhoff,

The U.S. Department of the Interior-Office of Insular Affairs (OIA) requests informal consultation with your agency in accordance with Section 7 of the Endangered Species Act (ESA) of 1973, as amended, (16 U.S.C. 1531 et. seq.) and consultation under the Migratory Bird Treaty Act (MBTA) of 1918 (16 U.S.C. 703-712; Ch. 128; July 13,1918; 40 Stat. 755) for the proposed project as described below.

The OIA has awarded a grant to the Guam Power Authority (GPA) to fund construction and subsequent operation by GPA of a single wind turbine as a pilot project that will assist OPA in determining the viability of utilizing larger scale wind turbines as a renewable energy source for Guam under their 2008 Integrated Resource Plan. The proposed project site would be located within and near the southern boundary of the Cotal Conservation Reserve about 100 to150-meters north of Route 17 within the village of Yona, Guam. (See Enclosure 1).

The proposed wind turbine would have a 32-meter rotor diameter with a nominal output of 275-kilowatts. The rotor will be attached to a 55-meter tubular, tilting guy-wired tower system that will be secured to a concrete base and anchor plates which will allow for the lowering and securing of the tower in the event of cyclone conditions. The rotor will have a peak height of 71-meters from its base to the tip of its rotor blades. (See Enclosure 2 for a preliminary project drawing). OPA had earlier funded and installed a 60-meter high meteorological tower at the project site to collect wind and weather data for energy production estimates in support of the pilot project. This tower will be dismantled to make way for constructing the wind turbine in its place.

The following mammalian and avian ESA-listed species are known to occur on Guam: the endangered Little Mariana Fruit Bat (Pteropus tokudae), the threatened Mariana Fruit Bat (Pteropus mariannus mariannus), endangered Mariana Swiftlet (Aerodramus bartschi), Mariana Crow (Corvus kubaryi), Mariana Common Moorhen (Gallinula chloropus guami), Guam Micronesian Kingfisher (Halcyon cinnamomina cinnamomina), Micronesian Megapode (Megapodius laperouse), Guam Bridled White-Eye (Zosterops

conspicillatus conspicillatus), and the Guam Rail (Gallirallus owstoni). The Guam Rail may also be protected under the MBTA. Please advise us if there are additional species on Guanl that are protected under either the ESA or the MBTA. The proposed project site is not located within or near designated critical habitats.

Early and on-going coordination efforts with Ms. Jodi Charrier of your office indicated that of the above species, the following may occur, or could reasonably be expected to occur, in the proposed action area: the threatened Mariana Fruit Bat, the endangered Mariana Common Moorhen and the endangered Mariana Swiftlet.

A biological survey was conducted for construction of the previously mentioned meteorological tower in the fall of2010. The survey was conducted over a two day period encompassing a circular area with a radius of 170-feet centered on the location of the tower (approximately 2-acres). The vegetation/habitat types observed were characterized as IntroducedlDisturbed Forest, Disturbed Savannah and Erosion Badlands. No threatened or endangered flora or fauna species were observed during the survey and existing site conditions were such that they would not provide suitable habitat for the fruit bay, moorhen or swiftlet. The survey report dated November 2010 is provided for your reference as Enclosure 3.

Based on Ms. Charrier's input on the affected species that may occur in the proposed action area and the results from the prior biological survey conducted for the project site, our assessment of the project's potential effects to the Mariana Fruit Bat, Mariana Common Moorhen and the Mariana Swiflet are as follows:

Mariana Fruit Bat. In a·uam, the bats primarily forage and roost in native limestone forests and feeds mostly on fruits. The vegetation, habitat and food sources are not especially attractive to the bat at the project site and it is unlikely that they would occur there, however, they could transit through the site to reach other locations to forage or areas to roost. Therefore, the project may affect, but is not likely to adversely affect the bat.

Mariana Common Moorhen. The moorhen's preferred habitat is wetlands that support about equal amounts of open water and vegetation. Because there are no wetlands in the project site, it is not desirable moorhen habitat and would not support foraging. The project's effect on the moorhen would be negligible and not reach a scale where take could occur. By definition then, the project's effect on the moorhen can be expected to be discountable and insignificant. Transit by the moorhen through the project site is unlikely but is not conclusively determined so the project may affect, but is not likely to adversely affect the moorhen.

Mariana Swiftlet. The Mariana Swiftlet roosts almost exclusively in natural caves, and occasionally in man-made caverns or tunnels. The preferred foraging areas for the swiftlet are along cliff lines, grassy hills and ravines; they also forage in limestone forests and ravine forests. The existing habitat at the project site is not suitable for roosting by the swiflet and they were not observed during the biological survey. They could

potentially transit through the project area to reach more suitable locations to forage and roost. Therefore, the project may affect, but is not likely to adversely affect the swiflet.

In order to make the wind turbine less attractive and more likely to be avoided by birds and bats, the following measures will be included by GPA into the project description:

a. Using a monopole tubular tower to eliminate the potential for perching and nesting;

b. Installing bird diverters/flappers on the guy wires;

c. Restricting construction activities to daylight hours to preclude the need for night time lighting;

d. Using minimal tower lighting with guidance from the Federal Aviation Administration;

e. Using minimal onsite lighting for buildings and operations using light fixtures with shields to direct light downward; and,

f. Limiting onsite vegetation to that which is already established and preventing new growth that would be attractive to the species.

GPA will also initiate an avian and bat mortality plan that will be conducted in two phases; a pre-construction and construction survey phase and a post-construction monitoring phase. Under the survey phase, a pre-construction biological survey will be conducted to encompass a larger area and supplement the information from the prior biological survey. The larger area will correspond with guidelines for wind turbine related mortality monitoring and consist of an area with dimensions twice the height of the pilot wind turbine (142 x 142-meters or approximately 5 acres). Observations will also be made up to and through the construction period from observation points to gather additional data of avian and bat species that may transit through the area during different times of the day and season to address concerns expressed by the Guam Division of Aquatic and Wildlife Resources. Post-construction mortality monitoring would take place once the turbine becomes operational and conducted over a two year period. The specifics of both phases are discussed in the avian and bat mortality plan which has been included as Enclosure 4 for your review.

Based on our assessment, the measures to be included in the project description and the execution of the proposed mortality monitoring plan, we seek and look forward to receiving your concurrence with our determinations that the proposed project may affect, but is not likely to adversely affect the Mariana Fruit Bat, Mariana Con1ll1on Moorhen, and the Mariana Swiftlet within 30 days of this letter.

Ms. Lynda Bordallo Aguon State Historic Preservation Officer Guam Historic Resources Division Department of Parks and Recreation Government of Guam 490 Chalan Palasyo Agana Heights, Guam 96910

Dear Ms. Aguon:

The U.S. Department of the Interior, Office ofInsular Affairs requests initiation of Section 106 coordination and consultation in compliance with the National Historic Preservation Act of 1966, as amended, and implementing regulations 36 CFR Part 800 (NHP A), for its proposed undertaking to fund the construction of a pilot wind turbine project on a I-acre site at Cotal, Guam by the Guam Power Authority (GPA). (See Enclosures 1 and 2 for project location maps). The proposed undertaking will be temporary in nature and its purpose is to assist GP A in determining the viability of larger scale wind turbines as a renewable energy source for Guam. The grantee and proponent for this proposal is the G P A.

The proposed wind turbine will have a 32-meter rotor diameter with a nominal output of 275 kilowatts. The rotor will be attached to a 55-meter tubular, tilting guy-wired tower system which will allow for the lowering and securing of the tower in the event of cyclone conditions. The tower will be secured to a concrete base and anchor plates. Eight additional reinforced concrete pads will be installed for guy wire anchors, winches, tower support, etc. Each of the pads will require excavation into to ground for stability and footings. Geotechnical investigations may alsq be conducted to insure suitable soil conditions for the concrete pads. (See illustrations at Enclosures 3 and 4.) Access to the project site will be via an existing dirt road. The Area of Potential Effect (APE) for the proposed undertaking would include the I-acre project site and the access road.

The Environmental Impact Assessment prepared by GP A (Enclosure 5) indicates that neither archaeological features nor historical sites were noted at the project site by the proponents. Therefore, we believe that the project's APE is devoid of any historic properties and thus a "no effect to historic properties" determination would be appropriate for the proposed project.

In compliance with Section 106 of the NHPA, we respectfully request your concurrence of this determination. If no response is received after 30 days from your receipt of this

letter, we will assume concurrence. A copy of this letter with attachments is also being sent by facsimile or electronically to individual entities identified by your office as interested parties to the Section 106 coordination and consultation.

,If you should have any questions, please contact me at (202) 219-1335, or by email to Faride_Kraft@ios.doi.gov.
