Re: Notice of Exempt Modification – Antenna Swap and RRU Add Property Address: 699 Old Main St. Rocky Hill, CT 06067

Applicant: AT&T Mobility, LLC Dear Ms. Bachman:

On behalf of AT&T, please accept this application as notification pursuant to R.C.S.A.

§16-50j-73, for construction that constitutes an exempt modification pursuant to R.C.S.A. §16- 50j-72(b) (2).

AT&T currently maintains a wireless telecommunications facility consisting of nine (9) wireless telecommunication antennas at an antenna center line height of 105-feet on an existing 150-foot monopole, owned by Crown Castle at 12 Gill St. Suite 5800, Woburn, MA 01801. AT&T now intends to swap (3) 4’ Powerwave 7770s for (1) 6’ Quintel QS66512-2 and (2) 8’ CCI TPA-65R-LCUUUU-H8 panel antennas in position [4] all sectors. AT&T would also like to relocate (3) existing 8’ CCI HPA-65R-BUU-H8 Panel Antennas from position [3] to position [2], all sectors. AT&T also wishes to add (1) RRUS-32 and (1) RRUS-32 B2 on position [4] all sectors, for a total of (6) RRUs 32s being added. Lastly, AT&T also intends to add (1) Raycap Squid as well as (2) DC Cables and (1) Fiber Cables to their configuration. All of the changes will take place on the existing antenna mount.

Per the attached Final Certificate of Zoning Compliance, the construction of the monopole was approved on November 5th, 1999, by the Zoning Board of the Town of Rocky Hill, CT. In addition, attached is a summary of the planned modifications including power density calculations reflecting the change in AT&T’s operations at the site. Also included is documentation of the structural sufficiency of the tower to accommodate the revised antenna configuration.

Please accept this letter pursuant to Regulation of Connecticut State Agencies §16-50j-73, for construction that

constitutes an exempt modification pursuant to R.C.S.A. § 16-5I0j-72(b) (2). In accordance with R.C.S.A., a copy of this letter is being sent to Kim Ricci, Zoning Enforcement Officer & Town Planner, Town of Rocky Hill, 761 Old Main St. Rocky Hill, CT 06067 and Claudia Baio, Town of Rocky Hill, 761 Old Main St. Rocky Hill, CT 06067. The land owner is the Town of Rocky Hill, and per above, they are being notified. In addition, a copy if being sent to the tower company, Crown Castle, 3 Corporate Park Drive, Suite 101, Clifton Park, NY 12065.

The following is a list of subsequent decisions by the Connecticut Siting Council:

EM-AT&T-119-120820 – AT&T Mobility notice of intent to modify an existing telecommunications facility located at 699 Old Main Street, Rocky Hill, Connecticut.

EM-AT&T-119-140210- American Telephone & Telegraph (AT&T) notice of intent to modify an existing telecommunications facility located at 699 Old Main Street, Rocky Hill, Connecticut.

EM-AT&T-119b-150320 – AT&T Mobility notice of intent to modify an existing telecommunications facility located at 699 Old Main Street, Rocky Hill, Connecticut.

EM-AT&T-119-170125 - AT&T notice of intent to modify an existing telecommunications facility located at 699 Old Main Street, Rocky Hill, Connecticut.

Page2

The planned modifications to AT&T’s facility fall squarely within those activities explicitly provided for in R.C.S.A. §16-50j-72(b) (2).

1. The proposed modifications will not result in an increase in the height of the existing tower. AT&T’s replacement antennas will be installed at the 105-foot level of the 150-foot monopole.

2. The proposed modifications will not involve any changes to ground-mounted equipment and, therefore, will not require and extension of the site boundary.

3. The proposed modifications will not increase the noise levels at the facility by six decibels or more, or to levels that exceed state and local criteria.

4. The operation of the modified facility will not increase radio frequency (RF) emissions at the facility to a level at or above the Federal Communications Commission (FCC) safety standard. A cumulative worst-case RF emissions calculation for AT&T’s modified facility is provided in the RF Emissions Compliance Report, included in Tab 2.

5. The proposed modifications will not cause a change or alteration in the physical or environmental characteristics of the site.

6. The tower and its foundation can support AT&T’s proposed modifications. (See Structural Analysis Report included in Tab 3).

For the foregoing reasons, AT&T respectfully submits that the proposed modifications to the above referenced telecommunications facility constitutes an exempt modification under R.C.S.A. §16-50j-72(b) (2).

NOTE: X, Y and Z indicate relative position of the bottom of the antenna to the origin location on the site, displayed in the model results diagram.Specifically, the Z reference indicates the bottom of the antenna height above the ground level unless otherwise indicated. The distance to the bottom ofthe antenna is calculated by subtracting half of the length of the antenna from the antenna centerline. Effective Radiated Power (ERP) is provided by theoperator or based on Sitesafe experience. The values used in the modeling may be greater than are currently deployed.

Note: Other operators exist on site but were not considered for this modeling because Sitesafe had no information on them.

4 Emission PredictionsIn the RF Exposure Simulations below all heights are reflected with respect to main site level. Inmost rooftop cases this is the height of the main rooftop and in other cases this can be groundlevel. Each different height area, rooftop, or platform level is labeled with its height relative tothe main site level. Emissions are calculated appropriately based on the relative height andlocation of that area to all antennas.

The Antenna Inventory heights are referenced to the same level.

Appendix B – Regulatory Background InformationFCC Rules and Regulations

In 1996, the Federal Communications Commission (FCC) adopted regulations for theevaluating of the effects of RF emissions in 47 CFR § 1.1307 and 1.1310. The guidelinefrom the FCC Office of Engineering and Technology is Bulletin 65 (“OET Bulletin 65”),Evaluating Compliance with FCC Guidelines for Human Exposure to Radio FrequencyElectromagnetic Fields, Edition 97-01, published August 1997. Since 1996 the FCCperiodically reviews these rules and regulations as per their congressional mandate.

FCC regulations define two separate tiers of exposure limits: Occupational or“Controlled environment” and General Public or “Uncontrolled environment”. TheGeneral Public limits are generally five times more conservative or restrictive than theOccupational limit. These limits apply to accessible areas where workers or thegeneral public may be exposed to Radio Frequency (RF) electromagnetic fields.

Occupational or Controlled limits apply in situations in which persons are exposed as aconsequence of their employment and where those persons exposed have beenmade fully aware of the potential for exposure and can exercise control over theirexposure.

An area is considered a Controlled environment when access is limited to these awarepersonnel. Typical criteria are restricted access (i.e. locked or alarmed doors, barriers,etc.) to the areas where antennas are located coupled with proper RF warningsignage. A site with Controlled environments is evaluated with Occupational limits.

All other areas are considered Uncontrolled environments. If a site has no accesscontrols or no RF warning signage it is evaluated with General Public limits.

The theoretical modeling of the RF electromagnetic fields has been performed inaccordance with OET Bulletin 65. The Maximum Permissible Exposure (MPE) limits utilizedin this analysis are outlined in the following diagram:

OSHA StatementThe General Duty clause of the OSHA Act (Section 5) outlines the occupational safetyand health responsibilities of the employer and employee. The General Duty clause inSection 5 states:

(a) Each employer –(1) shall furnish to each of his employees employment and a place of

employment which are free from recognized hazards that arecausing or are likely to cause death or serious physical harm to hisemployees;

(2) shall comply with occupational safety and health standardspromulgated under this Act.

(b) Each employee shall comply with occupational safety and health standards andall rules, regulations, and orders issued pursuant to this Act which are applicable tohis own actions and conduct.

OSHA has defined Radiofrequency and Microwave Radiation safety standards forworkers who may enter hazardous RF areas. Regulation Standards 29 CFR § 1910.147identify a generic Lock Out Tag Out procedure aimed to control the unexpectedenergization or start up of machines when maintenance or service is being performed.


Page 14

Appendix C – Safety Plan and ProceduresThe following items are general safety recommendations that should be administeredon a site by site basis as needed by the carrier.

General Maintenance Work: Any maintenance personnel required to workimmediately in front of antennas and / or in areas indicated as above 100% of theOccupational MPE limits should coordinate with the wireless operators to disabletransmitters during their work activities.

Training and Qualification Verification: All personnel accessing areas indicated asexceeding the General Population MPE limits should have a basic understanding ofEME awareness and RF Safety procedures when working around transmitting antennas.Awareness training increases a workers understanding to potential RF exposurescenarios. Awareness can be achieved in a number of ways (e.g. videos, formalclassroom lecture or internet based courses).

Physical Access Control: Access restrictions to transmitting antennas locations is theprimary element in a site safety plan. Examples of access restrictions are as follows:

Locked door or gate Alarmed door Locked ladder access Restrictive Barrier at antenna (e.g. Chain link with posted RF Sign)

RF Signage: Everyone should obey all posted signs at all times. RF signs play animportant role in properly warning a worker prior to entering into a potential RF Exposurearea.

Assume all antennas are active: Due to the nature of telecommunicationstransmissions, an antenna transmits intermittently. Always assume an antenna istransmitting. Never stop in front of an antenna. If you have to pass by an antenna,move through as quickly and safely as possible thereby reducing any exposure to aminimum.

Maintain a 3 foot clearance from all antennas: There is a direct correlation betweenthe strength of an EME field and the distance from the transmitting antenna. The furtheraway from an antenna, the lower the corresponding EME field is.

Site RF Emissions Diagram: Section 4 of this report contains an RF Diagram that outlinesvarious theoretical Maximum Permissible Exposure (MPE) areas at the site. Themodeling is a worst case scenario assuming a duty cycle of 100% for each transmittingantenna at full power. This analysis is based on one of two access control criteria:General Public criteria means the access to the site is uncontrolled and anyone cangain access. Occupational criteria means the access is restricted and only properlytrained individuals can gain access to the antenna locations.


Page 15

Appendix D – RF EmissionsThe RF Emissions Simulation(s) in this report display theoretical spatially averagedpercentage of the Maximum Permissible Exposure for all systems at the site unlessotherwise noted. These diagrams use modeling as prescribed in OET Bulletin 65 andassumptions detailed in Appendix E.

The key at the bottom of each RF Emissions Simulation indicates percentages displayedreferenced to FCC General Public Maximum Permissible Exposure (MPE) limits. Colorcoding on the diagram is as follows:

Areas indicated as Gray are predicted to be below 5% of the MPE limits. Grayrepresents areas more than 20 times below the most conservative exposure limit.

Green represents areas are predicted to be between 5% and 100% of the MPElimits. Green areas are accessible to anyone.

Blue represents areas predicted to exceed the General Public MPE limits but areless than Occupational limits. Blue areas should be accessible only to RF trainedworkers.

Yellow represents areas predicted to exceed Occupational MPE limits. Yellowareas should be accessible only to RF trained workers able to assess currentexposure levels.

Red represents areas predicted to have exposure more than 10 times theOccupational MPE limits. Red indicates that the RF levels must be reduced prior toaccess. An RF Safety Plan is required which outlines how to reduce the RF energy inthese areas prior to access.


Page 16

Appendix E – Assumptions and DefinitionsGeneral Model Assumptions

In this site compliance report, it is assumed that all antennas are operating at full powerat all times. Software modeling was performed for all transmitting antennas located onthe site. Sitesafe has further assumed a 100% duty cycle and maximum radiatedpower.

The modeling is based on recommendations from the FCC’s OET-65 bulletin with thefollowing variances per AT&T guidance. Reflection has not been considered in themodeling, i.e. the reflection factor is 1.0. The near / far field boundary has been set to1.5 times the aperture height of the antenna and modeling beyond that point is thelesser of the near field cylindrical model and the far field model taking into account thegain of the antenna.

The site has been modeled with these assumptions to show the maximum RF energydensity. Areas modeled with exposure greater than 100% of the General Public MPElevel may not actually occur, but are shown as a prediction that could be realized.Sitesafe believes these areas to be safe for entry by occupationally trained personnelutilizing appropriate personal protective equipment (in most cases, a personal monitor).

Use of Generic AntennasFor the purposes of this report, the use of “Generic” as an antenna model, or“Unknown” for an operator means the information about a carrier, their FCC licenseand/or antenna information was not provided and could not be obtained while on site.In the event of unknown information, Sitesafe will use our industry specific knowledge ofequipment, antenna models, and transmit power to model the site. If more specificinformation can be obtained for the unknown measurement criteria, Sitesaferecommends remodeling of the site utilizing the more complete and accurate data.Information about similar facilities is used when the service is identified and associatedwith a particular antenna. If no information is available regarding the transmittingservice associated with an unidentified antenna, using the antenna manufacturer’spublished data regarding the antenna’s physical characteristics makes moreconservative assumptions.

Where the frequency is unknown, Sitesafe uses the closest frequency in the antenna’srange that corresponds to the highest Maximum Permissible Exposure (MPE), resulting ina conservative analysis.

Definitions

5% Rule – The rules adopted by the FCC specify that, in general, at multiple transmittersites actions necessary to bring the area into compliance with the guidelines are theshared responsibility of all licensees whose transmitters produce field strengths or powerdensity levels at the area in question in excess of 5% of the exposure limits. In otherwords, any wireless operator that contributes 5% or greater of the MPE limit in an areathat is identified to be greater than 100% of the MPE limit is responsible taking correctiveactions to bring the site into compliance.

Compliance – The determination of whether a site is safe or not with regards to HumanExposure to Radio Frequency Radiation from transmitting antennas.

Decibel (dB) – A unit for measuring power or strength of a signal.

Duty Cycle – The percent of pulse duration to the pulse period of a periodic pulse train.Also, may be a measure of the temporal transmission characteristic of an intermittentlytransmitting RF source such as a paging antenna by dividing average transmissionduration by the average period for transmission. A duty cycle of 100% corresponds tocontinuous operation.

Effective (or Equivalent) Isotropic Radiated Power (EIRP) – The product of the powersupplied to the antenna and the antenna gain in a given direction relative to anisotropic antenna.

Effective Radiated Power (ERP) – In a given direction, the relative gain of a transmittingantenna with respect to the maximum directivity of a half wave dipole multiplied bythe net power accepted by the antenna from the connecting transmitter.

Gain (of an antenna) – The ratio of the maximum intensity in a given direction to themaximum radiation in the same direction from an isotropic radiator. Gain is a measureof the relative efficiency of a directional antennas as compared to an omni directionalantenna.

General Population/Uncontrolled Environment – Defined by the FCC, as an area whereexposure to RF energy may occur to persons who are unaware of the potential forexposure and who have no control of their exposure. General Population is alsoreferenced as General Public.

Generic Antenna – For the purposes of this report, the use of “Generic” as an antennamodel means the antenna information was not provided and could not be obtainedwhile on site. In the event of unknown information, Sitesafe will use our industry specificknowledge of antenna models to select a worst case scenario antenna to model thesite.

Isotropic Antenna – An antenna that is completely non-directional. In other words, anantenna that radiates energy equally in all directions.

Maximum Measurement – This measurement represents the single largest measurementrecorded when performing a spatial average measurement.

Maximum Permissible Exposure (MPE) – The maximum levels of RF exposure a personmay be exposed to without harmful effect and with acceptable safety factor.

Occupational/Controlled Environment – Defined by the FCC, as an area where RadioFrequency Radiation (RFR) exposure may occur to persons who are aware of the

3.1) Analysis Method

tnxTower (version 7.0.5.1), a commercially available analysis software package, was used to create athree-dimensional model of the tower and calculate member stresses for various loading cases.Selected output from the analysis is included in Appendix A.

3.2) Assumptions

1) Tower and structures were built in accordance with the manufacturer’s specifications.2) The tower and structures have been maintained in accordance with the manufacturer’s

specification.3) The configuration of antennas, transmission cables, mounts and other appurtenances are as

specified in Tables 1 and 2 and the referenced drawings.4) In accordance with discussions with CCI Corporate Engineering: Based on the assumption that

the monopole manufacturer (PiRod) has designed the flange plates at splices to adequatelydevelop the full capacity of the unreinforced shaft section using unpublished and/or proprietarymethodologies, we are assuming that if our analysis shows that both the existing shaft and theexisting flange bolts are at a usage capacity of 100% or less, then the existing flange plates areat a usage capacity of 100% or less and no additional analysis of the flange plate is required.

5) Monopole has been reinforced in conformance with the referenced modification documents.

This analysis may be affected if any assumptions are not valid or have been made in error. Paul J.Ford and Company should be notified to determine the effect on the structural integrity of the tower.
