The existing Personal Wireless Services Facility (PWSF) was granted Use Process III approval under File No: 02-101491,and was modified under Use Process I File No: 03-104778. The current Use Process I application is hereby approved. The modification consists'of replacing the existing close -mount two -antenna apparatus with a structure comprised of three 13-foot T-arms, each supporting three antennas whose dimensions are similar to the existing antennas. The proposed modified antenna structure would be mounted at an elevation of 80 feet on the monopole. This is the same elevation as the existing AT&T antennas. The monopole currently supports a similar Verizon nine -antenna array structure at an elevation of 100 feet. No new equipment cabinets are proposed with this application. The site is zoned multi -family (RM3600). Pursuant to Federal Way City Code (FWCC) Section 22-681, PWSFs are permitted in this zone, pursuant to Use Process III review. However, pursuant to FWCC Section 22-32.2, improvements and/or additions to an existing developed site that are exempt from State Environmental Policy Act review, shall be processed as a Process I, when meeting the criteria set forth in this code section. The proposed minor modifications meet the exemption criteria identified in Washington Administrative Code (WAC) 197-11-800(27), and the criteria of FWCC Section 22-32.2, and as such this project has been reviewed as a Process 1. The applicant shall contact the Planning Division of the Department of Community Development Services for a final inspection of the PWSF. In conjunction with the inspection, the applicant shall submit an affidavit to the Planning Division that verifies the PWSF has been installed in accordance with the approved plans for the application. The antennas must be of a non -reflective color that will be neutral and unobtrusive. This approval does not exempt the project from other local, state, and federal permit requirements. Pursuant to FWCC Section 22-972, within six months of issuance of the permit for the facility, you must submit a project implementation report providing cumulative field measurements of radio frequency (EMF) per densities of all antennas installed at the site. This approval is also subject to five- and ten-year permit limitations identified in FWCC Section 22-974 (enclosed). - - L.": -. Ms. Telsdhow January 7, 2005 Page 2 This decision shall not waive compliance with future City of Federal Way codes, policies, and standards relating to this project site. The effective date of this decision is January 10, 2005. Pursuant to FWCC Section 22-355, any person who received notice of the decision may appeal the administrative decision to the Hearing Examiner by January 24, 2005. In that you are the only party of record for this application, you may waive your right to appeal. The City must receive this waiver in writing. If you choose to waive your right to appeal, you could begin work on the proposal on January 10, 2005, provided you have obtained an electrical permit for the proposal by that date.

Yroposed A W a xr summary There is an existing AWS wireless communications facility located on the 100'± monopole at 2101 South 324ffi Street, in Federal Way, WA. AWS is proposing to make the following antenna modifications to the facility: swap out each existing Allgon 7580.00 antenna with two Allgon 7721.00 antennas, and one Kathrein 739 684 antenna. The proposed Allgon antennas have a horizontal beam width of 65°, while the proposed Kathrein antenna has a horizontal beam width of 68°; all proposed antennas are to be mounted at the radiation center specified in table 1 above. There will be no proposed equipment installation, as AWS houses sufficient equipment to accommodate the antenna swaps. In addition to the AWS wireless facility, there is 1 additional 1900 MHz PCS carrier on the monopole. Figure 1 below shows an aerial view of the proposed facility. Figure 1. Aerial view of the proposed facility Federal Way East (SS67) October 20, 2004, Rev. 0 ENGIM1FeERING Page 2 PROTOCOL: This study, and the calculations performed therein, is based on OET Bulletin 651. In particular, equation 10 from section 2 of the guideline is used as a model (in conjunction with known antenna 1 radiation patterns) for calculating the power density at different points of interest. This information will be used to judge the RF exposure level incident upon the general population, and any employee present in the area. It should be noted that ground reflection of RF waves has been 1 taken into account. ENVIRONMENTAL EVALUATION: According to Table 2 in Appendix A of Bulletin 65, a broadband PCS facility is subject to routine environmental evaluation if the height above ground level to the lowest point on a non -building mounted antenna is less than 10m, and the total power of all channels in a given sector is in excess of 2000W ERP. The height above ground level to the lowest point of the antenna in question is 77'-10"± (23.7 m); therefore, this facility is exempt from routine environmental evaluation. FCC's MAXIMUM PERMISSIBLE EXPOSURE (MPE) LINUT: In order to evaluate the RF exposure level, the power density at several locations of interest will be determined. Equation 10 from Bulletin 65 is reproduced here as equation 1: S _ 33.4F2ERP (1) R2 Where: S = Power density [,uW/cm2] ERP = Effective radiated power [W] R = Distance [m] F = Relative fieldfactor (relative numeric gain) NOTE: At the time of this investigation the name of the additional carrier along with the relevant antenna information is unknown. As a result, the following assumptions are made in order to facilitate our calculations: 1. The analysis will be performed assuming a worst -case per -sector ERP value of 2000W 2. A worst -case relative field factor value will be assumed for each scenario based on j previous experience 3. The sector azimuths for the unknown carrier are assumed to coincide with those of AWS in 1 order to imitate a worst -case scenario J Scenario 1: Standing beside the monopole JA six-foot tall person standing beside the monopole will be approximately 74'-0" (22.6 m) below the AWS radiation center, and 94'-0" (28.6 m) below carrier 1's radiation center. Analyzing the J worst -case scenario, we utilize the assumptions stated in the `note' above, and also assume that each carrier is transmitting the maximum number of channels, with each channel at its maximum 1 Cleveland, Robert F, et al.

Worst -case predicted values for scenario 1. The Maximum Permissible Exposure (MPE) limit for general population/uncontrolled exposure is 1000 µW/cm2 for 1900 MHz facilities, and 567 µW/cm2 for 850 MHz facilities2. At this location, the total power density for the proposed and existing PCS facilities is calculated to be 0.29% of the MPE limit, and was calculated by adding the four values in the last column of table 2. Scenario 2: Standing on the rooftop of the nearby house beneath sector A main beam } Another location where the general public may experience a higher level of RF exposure is on the rooftop of a nearby house located approximately 82' north of the monopole. A six-foot tall person i standing on this rooftop would be approximately 5F-0" (15.5 m) below the AWS radiation center, and 71'-0" (21.6 m) below carrier l's radiation center. Again, we perform an analysis of the worst -case scenario by utilizing the assumptions stated in the `note' above, and assuming that each antenna is radiating the maximum number of channels, with each channel at its maximum power level. Please refer to scenario 2 in appendix A for the complete geometry. The calculations for this location are shown In table 3below. Carrier Max.

Worst -case predicted values for scenario 2. The total power density at this location was calculated to be 0.82% of the MPE limit. _ l Under "worst -case" conditions, the calculations shown above predict that the maximum possible RF exposure is 0.82% of the MPE limit. Therefore, the proposed AWS antenna modifications co - locating with the existing facilities will comply with the general population/uncontrolled limit. FCC COMPLIANCE: JOnly trained persons will be permitted to climb the monopole and access the facility. They will be made fully aware of the potential for RF exposure and can choose to exercise control over their exposure that is within the occupational/controlled limits. The general population/uncontrolled exposure near the facility including persons on the ground level, inside or on existing buildings, and in nearby open areas will have RF exposure much lower than the "worst -case" scenario, which is only a small fraction of the MPE limit. 2 Ibid., page 67.
