PROJECT SUMMARY
Consideration of a Conditional Use Permit for an unmanned wireless facility (cell tower) located on the east side of Ward Avenue, approximately 500 feet north of the intersection of West Las Palmas Avenue, APN 048-048-010. The facility would include an 84.9' tall decorative bell tower, an 8'x8' pre-cast concrete shelter, and a 30 KW generator, enclosed by a solid wall. A draft Negative Declaration has been prepared noting that the project Would not have a significant impact on the environment under the California Environinental
APPLICANT AND SITE INFORMATION
Applicant: New Cingular Wireless PCS
Property Owner: City of Patterson
Environmental Review: Draft Negative Declaration
Location: East side of Ward Avenue, approximately 500
feet north of West Las Palmas Avenue
Assessor Parcel Numbers: 048-048-010
Project Size: Approximately 900 sq. ft., excluding an access and utility easement
General Plan Designation: HR, High-density Residential
Zoning Designation: HR, High-density Residential
Present Use: Existing Vacant Space
Surrounding Land Uses: Single family housing
PROJECT DESCRIPTION AND ANALYSIS
Conditional use permit review is used to determine whether a land use is, and will continue to be, compatible with the current and potential surrounding land uses and to ensure that the use will not become a nuisance to the surrounding land uses. Cell towers typically require a conditional use permit, due to the potential for aesthetic and maintenance issues associated with a structure of this height and mass.
The project is an unmanned wireless facility, consisting of an 84.9' tall decorative bell tower, an 8' × 8' pre-cast concrete shelter, and a 30 KW generator, enclosed by a solid wall. The project would be located near the southwest corner of the noted lot, on a 900 square foot area. An access easement would be extend from Ward Avenue to provide all- weather access to the site.
1 The project site is located on City-owned property purchased in 2019 and approved for the Centennial Park project. This park is a joint effort between the City and the Patterson Joint Unified School District. The site would include facilities such as a community center, the school district's performing arts theater, playgrounds, sport courts, and other recreation facilities.
Aesthetics
To conceal antennas and equipment as much as possible, the Municipal Code requires that all equipment shall be obscured from view or disguised, so as not to appear as telecommunication equipment. The City typically pursues towers disguised as palm trees, related to this requirement, however, in this instance, such a "mono-palm" may look out of place. The proposed project includes a tower disguised as a decorative bell tower, and a solid wall to screen the ground equipment from view. The bell tower design was selected to blend with the proposed architecture found in the community generally, and with the planned Centennial Park proposal specifically. The bell would be for aesthetic purposes only and would not be used to generate sound
To further reduce the potential aesthetic impact of cell towers on the skyline, co-location, or the placement of additional equipment on existing towers is encouraged through a staff level approval process. The proposed project includes space allowing for such co-location.
Noise
The project includes a generator to serve the facility during power outages. A noise analysis was prepared and reviewed as part of the environmental review. This study determined that the project would not generate noise levels that are considered significant.
Height
The municipal code allows tower to project a maximum of 15 feet above the maximum height outlined in the zoning district where it is located. The maximum height allowed in the High Density Residential Zone, where the project is located, is 45'. The 15' projection would allow a maximum height of 60°. As noted, the applicant is requesting an 84.9° tower. The municipal code also includes provisions, specific to wireless communications towers, allowing the Planning Commission to approve additional height, as long as the tower meets specific criteria:
1) The project is required to show that the additional height is required to provide a more efficient coverage pattern. The applicant has provided information illustrating the existing coverage gap in the localized area and how the tower would fill that gap. 2) The municipal code requires that only facilities that are totally enclosed within a permitted building shall be allowed within two hundred percent of the fall zone of the facility to any existing residential district within the City. The fall zone is considered to be equivalent to the maximum height of the tower. In this case, the nearest residence is more than 200 feet from the tower site, well over the required distance. 2 ENVIRONMENTAL REVIEW
An initial study prepared for this project concludes that the project will not have a significant impact on the environment and a draft negative declaration has been prepared reflecting this.
ALTERNATIVE ACTIONS
1. Determine that the findings for the Negative Declaration, Conditional Use Permit and Variance can be made, and motion to adopt Negative Declaration #2021-02 and approve Conditional Use Permit #2020-03 subject to the conditions recommended in the staff report.
2. Determine that the findings for the Negative Declaration, Conditional Use Permit and /ariance can be made, and motion to adopt Negative Declaration #2021-02 anc approve Conditional Use Permit #2020-03 subject to the conditions recommended ir the staff report with changes/revisions as may be submitted by the Commission.
3. Determine that the findings for the Negative Declaration, Conditional Use Permit cannot be made and deny Conditional Use Permit #2020-03.
FINDINGS
To adopt the Negative Declaration, the Planning Commission must find the following:
1. The project will not have a significant adverse effect on water or air quality or increase noise levels;
2. The project will not have a significant adverse impact on the flora and fauna of the area;
3. The project will not degrade the aesthetic quality of the area;

c. Create impacts for a project which are individually limited, but cumulatively considerable;
d. Create environmental effects which will cause substantial adverse effects on human beings, either directly or indirectly;
3 6. The Negative Declaration was prepared in compliance with CEQA and the CEQA Guidelines.
To approve the conditional use permit, the Planning Commission must find the following:
1. That the requested conditional use permit is consistent with the city general plan and the zoning code.
2. That the establishment, maintenance, or operation of the proposed use or structure will conform to the requirements and intent of the zoning code; and that such proposed use or structure will not, under the circumstances of the particular case or as conditioned, be injurious or detrimental to the health, safety, or general welfare of persons or property in the vicinity of the proposed use, or to the general welfare of the city.

II. Project Description
The project assessed by this initial study considers the construction and operation of an unmanned wireless facility, consisting of an 84.9' tall decorative bell tower, an 8'x8 pre- cast concrete shelter, and a 30 KW generator, enclosed by a solid wall. The project site is located in High Density Residential Zone, on a site approved for a community park.
Environmental Setting
The project site is generally vacant and is part of an undeveloped section of the Centennial Park project, a joint project between the City of Patterson and the Patterson Joint Unified School District. The Centennial Park plan includes a future community center, an under-construction, school district performing arts theater, and various other outdoor recreation uses. Development bordering the site includes single family housing to the west, the Patterson Community Complex to the southwest, and generally vacant land, with some residences located to the north, east, and south. See Figure 1. No off-site work is planned. See Figure 2.

CITY OF PATTERSON, INITIAL STUDY OF ENVIRONMENTAL IMPACT 4 III. Initial Study Environmental Checklist
This section discusses potential environmental impacts associated with approval of the proposed project.
The following guidance, adapted from Appendix I of the State CEQA Guidelines, was followed in answering the checklist questions:
1. A brief explanation is required for all answers except "No Impact" answers that are adequately supported by the discussion. A "No Impact" answer is adequately supported if the discussion shows that the impact simply does not apply to projects like the one involved (e.g., the project falls outside a fault rupture zone). A "No Impact" answer should be explained when it is based on project-specific factors as well as general standards (e.g., the project will not expose sensitive receptors to pollutants, based on a project-specific screening analysis).
2. All answers must take account of the whole action involved, including offsite as well as onsite, cumulative as well as project-level, indirect as well as direct, and construction as well as operational impacts.
3. All analyses must be based on a comparison between conditions that would occur if the project were implemented and existing conditions (also known as baseline conditions).
4. "Potentially Significant Impact" is appropriate if there is substantial evidence that an effect is significant. If there are one or more "Potentially Significant Impact" entries when the determination is made, an EIR is required.
5. "Potentially Significant unless Mitigation Incorporated" applies where the incorporation of mitigation measures has reduced an effect from "Potentially Significant Impact" to a "Less-Than-Significant Impact." The lead agency must describe the mitigation measures, and briefly explain how they reduce the effect to a less-than-significant level (mitigation measures from earlier analyses may be cross-referenced).
6. Earlier analyses may be used where, pursuant to the tiering, program EIR, or other CEQA process, an effect has been adequately analyzed in an earlier EIR or negative declaration (State CEQA Guidelines Section 15063|c|[D]). Earlier analyses are discussed in the project description above under "Previous Environmental Documents and Site-Specific Information".
CITY OF PATTERSON, INITIAL STUDY OF ENVIRONMENTAL IMPACT 5 The discussion that follows each section of checklist questions:
analyzes previously certified environmental analysis and/or mitigation relevant to the issue, including the potential for each effect to be significant and adverse and standard requirements and measures that will preclude adverse impacts; • describes proposed measures that will preclude adverse impacts; • analyzes the potential for residual or remaining significant adverse impacts following implementation of the project and all previously identified, standard, and proposed requirements and measures; and
• summarizes the applicable mitigation measures established by the various support documents and project-specific measures that will reduce the impacts to a less-than- significant level.
Identification of the potential for residual significant adverse environmental impacts would trigger the need for preparation of an EIR. For issue areas in which no significant adverse impact would result or impacts would be reduced to a less-than-significant level by mitigation, further analysis is not required.

Setting/
The project consists of a wireless communication facility consisting of an 84.9' tower and associated equipment within the High Density Residential General Plan District and the High Density Residential Zone.
Discussion
a,c. "Communication and Equipment Buildings" are permitted with a conditional use permit in the High Density Residential Zone. The municipal code allows communication equipment to reach a maximum height of 60' in the High Density Residential Zone, however, does allow the Planning Commission to approve an exception where additional height above the maximum may be approved, provided that the applicant provides information demonstrating that the increased height is necessary for a more efficient development and coverage pattern. In this instance, the applicant is requesting an exception to allow the additional 24.9' in height with information showing that the increased height adequately serves coverage gaps in the City of Patterson. The code also includes provisions related to minimum distances for towers from residences and residential zones. The project is located at least 180 feet from the nearest existing residence, sufficiently distant to meet required "fall distance" criteria and, while the project is located in the high density residential zone, the City has purchased the land and the City Council has approved the Centennial Park plan for the entire site, effectively removing any potential for residential development in the immediate area.
CITY OF PATTERSON, INITIAL STUDY OF ENVIRONMENTAL IMPACT 7 The project has been designed with the look of a decorative bell tower, both to screen the cell tower use and to blend in with the surrounding development contemplated as part of the Centennial Park project.
Conclusion
The proposed project is not anticipated to significantly impact agricultural land or land use compatibility.

Setting
Currently, the San Joaquin Valley Air Basin is classified as a "Severe non-attainment" area for both the federal and State standards for ozone and a "serious" non-attainment area for the federal standard for respirable particulate matter (PMro, or particles 10 microns or smaller in diameter). Emissions of these air pollutants, and their precursors, will increase as a result of motor vehicle trips generated by the project, and from grading and onstruction operations. Together, these activities may hinder efforts to achieve an‹ maintain air quality standards established by federal and State laws.
Discussion
a. Development of the project site will result in short-term air pollutant emissions and dust generation from construction activities. Such activities will generate short-term fugitive dust and vehicle exhaust emissions as a result of excavation, grading, and construction- related vehicle trips.
Construction Emissions
A project's construction phase produces many types of emissions, but PM-10 is the pollutant of greatest concern. PM-10 emissions can result from a variety of construction activities, including excavation, grading, demolition, vehicle travel on paved and unpaved surfaces, and vehicle exhaust. Construction-related emissions can cause substantial increases in localized concentrations of PM-10, as well as affecting PM-10 compliance with ambient air quality standards on a regional basis. Particulate emissions from construction activities can lead to adverse health effects as well as nuisance concerns such as reduced visibility and soiling of exposed surfaces.
The SJVUAPCD's approach to CEQA analyses of construction impacts is to require implementation of effective and comprehensive control measures rather than to require CITY OF PATTERSON, INITIAL STUDY OF ENVIRONMENTAL IMPACT 12 detailed quantification of emissions. PM-10 emitted during construction can vary greatly depending on the level of activity, the specific operations taking place, the equipment being operated, local soils, weather conditions, and other factors, making quantification difficult. Despite this variability in emissions, experience has shown that there are a number of feasible control measures that can be reasonably implemented to significantly reduce PM-10 emissions from construction. The SJVUAPCD has determined that compliance with Regulation VIII for all sites and implementation of all other control measures as appropriate, depending on the size and location of the project site will constitute sufficient mitigation to reduce PM-10 impacts to a level considered less-than- significant.
San Joaquin Valley Unified Air Pollution Control District air quality mitigation measures are already included as mitigations for all projects as standard procedure to address these issues. Additionally, appropriate policies are dealt with in the 2010 General Plan EIR:
The City shall require all of the following as a condition of project approval of future development projects:
• All disturbed areas, including storage piles, which are not being actively utilized for construction purposes, shall be effectively stabilized of dust emissions using water, chemical stabilizer/suppressant, covered with a tarp or other suitable cover or vegetative ground cover.
• All on-site unpaved roads and off-site unpaved access roads shall be effectively stabilized of dust emissions using water or chemical stabilizer/suppressant. • All land clearing, grubbing, scraping, excavation, land leveling, grading, cut & fill, and demolition activities shall be effectively controlled of fugitive dust emissions utilizing application of water or by presoaking.
• With the demolition of buildings up to six stories in height, all exterior surfaces of the building shall be wetted during demolition.
• When materials are transported off-site, all material shall be covered, or effectively wetted to limit visible dust emissions, and at least six inches of freeboard space from the top of the container shall be maintained.
• All operations shall limit or expeditiously remove the accumulation of mud or dirt from adjacent public streets at the end of each workday. (The use of dry rotary brushes is expressly prohibited except where preceded or accompanied by sufficient wetting to limit the visible dust emissions.) (Use of blower devices is expressly forbidden.) • Following the addition of materials to, or the removal of materials from, the surface of outdoor storage piles, said piles shall be effectively stabilized of fugitive dust emissions utilizing sufficient water or chemical stabilizer/suppressant. • Within urban areas, track-out (earth material deposited on City streets by construction equipment) shall be immediately removed when it extends 50 or more feet from the site and at the end of each workday.
• Any site with 150 or more vehicle trips per day shall prevent carryout and track-out. • Limit traffic speeds on unpaved roads to 15 mph;
CITY OF PATTERSON, INITIAL STUDY OF ENVIRONMENTAL IMPACT 13 • Install sandbags or other erosion control measures to prevent silt runoff to public roadways from sites with a slope greater than one percent. • Install wheel washers for all exiting trucks, or wash off all trucks and equipment leaving the site;
• Install wind breaks at windward side(s) of construction areas; • Suspend excavation and grading activity when winds exceed 20 mph; and Limit area subject to excavation, grading, and other construction activity at any one time. Regardless of wind speed, an owner/operator must comply with Regulation VIII's 20 percent opacity limitation.
a. Impacts associated with the project are related to construction activities. Such impacts are temporary and have been addressed through the listed measures. As a result, no significant impact is anticipated.
Conclusion
The project will not result in significant impacts to air quality.

Setting/Discussion
Endangered, threatened, or rare species in the Patterson area include the San Joaquin Kit Fox (Vulpes macrotis mutica), Swainson's Hawk (Buteo swainsoni), Western Pond Turtle (Clemmys marmorata), and Burrowing Owl (Athene cunicularia). The San Joaquin Kit Fox's preferred habitat is grassland and rolling hills. Swainson's Hawk and Burrowing Owl both prefer grasslands.
The project is located on vacant land, previously used for agricultural purposes in an otherwise urbanized area. Potential impacts associated with biological resources were addressed in the 2010 General Plan EIR.

Where the location of outdoor activity areas is unknown, the exterior noise level standard shall be applied to the property line of the receiving land use.
As determined for a typical worst-case hour during periods of use. 3 Where it is not possible to reduce noise in outdoor activity areas to 60 Db Ldn/CNEL or less using a practical application of the best available noise reduction measures, an exterior noise level of up to 65 Db Ldn/CNEL may be allowed. provided that available exterior noise level reduction measures have been implemented and interior noise levels are in compliance with this table.
Noise is typically expressed in decibels (dB). The decibel scale is logarithmic because of the physical characteristics associated with noise transmission and reception. For example, a
3.0 decibel (dB) increase in noise levels normally results in a doubling of noise energy; however, because of the structure of the human auditory system, a 10-decibel increase is required to perceive a doubling of noise. A 1- to 2-decibel change in ambient noise levels is CITY OF PATTERSON, INITIAL STUDY OF ENVIRONMENTAL IMPACT 19 generally not perceptible to the human ear. The A-weighted decibel (dBA) incorporates the human ear's sensitivity to sounds of different frequencies. On this scale, the sound level of normal talking is about 60 to 65 dBA.
Noise levels diminish (or attenuate) as distance from the source increases based on an inverse square rule, but the rate constant varies with the type of sound source. Sound from point sources, such as industrial facilities, attenuates at a rate of 6 dBA per doubling of distance. Heavily-traveled roads with few gaps in traffic behave as continuous line sources with an attenuation rate of 3 dBA per doubling of distance. Otherwise, roads typically have an attenuation rate of 4.5 dBA.
Construction work is the main source of noise as a result of the project.
A noise study was prepared for the project which reviewed predicted noise levels associated with operation of the facility. The study determined that the project's noise exposure would be less than the City's required noise generation maximum requirements.
No ongoing significant noise impacts are expected as a result of this project.
Discussion
a., b. Noise levels on the project site will increase as a result of construction activities associated with the project. Such noise is temporary and is not considered significant. Noise from the generator is not expected to exceed noise standards outlined in the 2010 General Plan EIR. No significant ongoing impacts are anticipated.
Conclusion
Noise levels resulting from construction and operation of the project have been addressed and can be mitigated per the 2010 General Plan EIR.

Introduction
The CVL01687 Patterson 2 AT&T Wireless Unmanned Telecommunications Facility Project (project) proposes the installation of cellular equipment within a lease area located at 15421 North gth Street in Patterson, California (APN: 048-048-010). The externally mounted HVAC unit of a pre-manufactured concrete walk-in cabinet and an emergency diesel standby generator have been identified as the primary noise sources associated with the project. The project overall site plan is shown on Figure 1. The studied site drawings are dated September 16, 2020.
Bollard Acoustical Consultants, Inc. (BAC) has been contracted by Complete Wireless Consulting, Inc. to complete an environmental noise assessment regarding the proposed project cellular equipment operations. Specifically, the following assessment addresses daily noise production and exposure associated with operation of the project emergency generator and HVAC equipment.
Please refer to Appendix A for definitions of acoustical terminology used in this report. Appendix B illustrates common noise levels associated with various sources.
Criteria for Acceptable Noise Exposure
City of Patterson General Plan
The Health and Safety Element of the City of Patterson General Plan establishes performance standards for non-transportation (stationary) noise sources, such as those proposed by the project. The non-transportation noise level limits contained in the General Plan have been reproduced and are provided below in Table 1.

HVAC Equipment Noise Source and Reference Noise Level
The project proposes the installation of a pre-manufactured concrete walk-in cabinet equipped with one (1) externally mounted HVAC unit within the equipment lease area illustrated on Figure
1. According to the project site plan, the HVAC unit assumed for the project is a Marvair Airxcel, Inc. Model ECUA18ACA. Based on reference noise level data obtained from the manufacturer (Marvair Airxcel, Inc.), this specific HVAC unit model has a reference noise level of 62 dB at a distance of 5 feet. The manufacturer's noise level data specification sheet for the proposed HVAC equipment is provided as Appendix C.
Generator Noise Source and Reference Noise Level
The project also proposes the installation of an emergency standby diesel generator within the lease area to maintain cellular service during emergency power outages. Based on the project site plans, the generator assumed for this project is a Generac Industrial Power Systems Model SDO30. It is further assumed that the proposed generator will be equipped with the Level 2 Acoustic Enclosure resulting in a reference noise level of 68 dB at a distance of 23 feet. The manufacturer's noise level data specification sheet for the proposed generator and acoustical enclosure is provided as Appendix D.
The generator which is proposed at this site would only operate during emergencies (power outages) and brief daytime periods for periodic maintenance/lubrication. According to the project applicant, testing of the generator would occur twice per month, during daytime hours, for a duration of approximately 15 minutes. The emergency generator would not operate at night, except during power outages. It is expected that nighttime operation of the project emergency generator would be exempt from the city's exterior noise exposure criteria due to the need for continuous cellular service provided by the project equipment.
Predicted Facility Noise Levels at the Nearest Noise-Sensitive Property Lines According to footnote 1 of Table 1, the city's noise standards are to be applied at the property line of a noise-sensitive land use. The nearest noise-sensitive uses have been identified as low- density residential uses located west of the project. According to the project site plans, the proposed cellular facility lease area maintains a separation of approximately 208 feet from the nearest residential property line to the west, APN: 021-036-043. Assuming standard spherical spreading loss (-6 dB per doubling of distance), project equipment noise exposure at the property line of the nearest residential use was calculated and the results of those calculations are presented in Table 2. Satisfaction of the city's noise criteria at the nearest residential use would ensure for satisfaction of the criteria at residential uses located farther away.

Because the proposed HVAC unit could potentially be in operation during nighttime hours, the operation of the HVAC unit would be subject to the General Plan nighttime noise level standard of 45 dB Leg (Table 1). As indicated in Table 2, the predicted HVAC equipment noise level of 30 dB Leq at the property line of the nearest noise-sensitive use (low-density residential) would satisfy the General Plan 45 dB Leq nighttime noise level limit by a wide margin. As a result, no further consideration of HVAC equipment noise mitigation measures would be warranted for the project.
Because the project generator would only operate during daytime hours for brief periods required for testing and maintenance, and because generator noise is assumed to be exempt during emergency operations, noise from the generator would be subject to the General Plan daytime noise level standard of 70 dB Lmax. As shown in Table 2, the predicted generator noise level of 49 dB Lmax at the property line of the nearest noise-sensitive use (low-density residential) would satisfy the General Plan 70 dB Lmax daytime noise level standard by a wide margin. As a result, no further consideration of emergency generator noise mitigation measures would be warranted for the project.
Conclusions
Based on the equipment noise level data and analyses presented above, project-related equipment noise exposure is expected to satisfy the applicable City of Patterson General Plan noise level criteria at the closest noise-sensitive uses. As a result, no further consideration of project equipment noise mitigation measures would be warranted for this project.
This concludes our environmental noise assessment for the proposed CVL01687 Patterson 2 AT&T Cellular Facility in Patterson, California. Please contact BAC at (916) 663-0500 or [email protected] with any questions or requests for additional information.

Appendix A
Acoustical Terminology
Acoustics The science of sound.
Ambient The distinctive acoustical characteristics of a given space consisting of all noise sources Noise audible at that location. In many cases, the term ambient is used to describe an existing or pre-project condition such as the setting in an environmental noise study.
Attenuation The reduction of an acoustic signal.
A-Weighting A frequency-response adjustment of a sound level meter that conditions the output signal to approximate human response.
Decibel or dB Fundamental unit of sound, A Bell is defined as the logarithm of the ratio of the sound pressure squared over the reference pressure squared. A Decibel is one-tenth of a Bell.
CNEL Community Noise Equivalent Level. Defined as the 24-hour average noise level with noise occurring during evening hours (7 - 10 p.m.) weighted by a factor of three and nighttime hours weighted by a factor of 10 prior to averaging.
Frequency The measure of the rapidity of alterations of a periodic signal, expressed in cycles per second or hertz.
Lon Day/Night Average Sound Level. Similar to CNEL but with no evening weighting.
Leg Equivalent or energy-averaged sound level.
Lmax The highest root-mean-square (RMS) sound level measured over a given period of time.
Loudness A subjective term for the sensation of the magnitude of sound.
Masking The amount (or the process) by which the threshold of audibility is for one sound is raised by the presence of another (masking) sound
Noise Unwanted sound.
Peak Noise The level corresponding to the highest (not RMS) sound pressure measured over a given period of time. This term is often confused with the Maximum level, which is the highest RMS level.
RTen The time it takes reverberant sound to decay by 60 dB once the source has been removed.
Sabin The unit of sound absorption. One square foot of material absorbing 100% of incident sound has an absorption of 1 sabin.
SEL A rating, in decibels, of a discrete event, such as an aircraft flyover or train passby, that compresses the total sound energy of the event into a 1-s time period.
Threshold The lowest sound that can be perceived by the human auditory system, generally of Hearing considered to be 0 dB for persons with perfect hearing.
Threshold Approximately 120 dB above the threshold of hearing of Pain

EXECUTIVE SUMMARY
Purpose of Report
EnviroBusiness Inc. (dba EBI Consulting) has been contracted by AT&T Mobility, LLC to conduct radio frequency electromagnetic (RF-EME) modeling for AT&T Site CVL01687 located at 15421 N 9th Street in Patterson, California to determine RF-EME exposure levels from proposed AT&T wireless communications equipment at this site. As described in greater detail in Section I.0 of this report, the Federal Communications Commission (FCC) has developed Maximum Permissible Exposure (MPE) Limits for general public exposures and occupational exposures. This report summarizes the results of RF-EME modeling in relation to relevant FCC RF-EME compliance standards for limiting human exposure to RF-EME fields.
This report contains the RF EME analysis for the site, including the following:
• Site Plan with antenna locations
• Graphical representation of theoretical ME fields based on modeling • Graphical representation of recommended signage and/or barriers This document addresses the compliance of AT&T's transmitting facilities independently and in relation to all collocated facilities at the site.
Statement of Compliance
A site is considered out of compliance with FCC regulations if there are areas that exceed the FCC exposure limits and there are no RF hazard mitigation measures in place. Any carrier which has an installation that contributes more than 5% of the applicable MPE must participate in mitigating these RF hazards.
As presented in the sections below, based on worst-case predictive modeling, there are no modeled exposures on any accessible ground walking/working surface related to ATT's proposed antennas that exceed the FCC's occupational and/or general public exposure limits at this site.
As such, the proposed AT&T installation is in compliance with FCC regulations upon proper installation of recommended signage and/or barriers.
AT&T Recommended Signage/Compliance Plan
AT&T's RF Exposure: Responsibilities, Procedures & Guidelines document, dated October 28, 2014, requires that:
1. All sites must be analyzed for RF exposure compliance;
2. All sites must have that analysis documented; and
3. All sites must have any necessary signage and barriers installed.
Site compliance recommendations have been developed based upon protocols presented in AT&T's RF Exposure: Responsibilities, Procedures & Guidelines document, dated October 28, 2014, additional guidance provided by AT&T, EBl's understanding of FCC and OSHA requirements, and common industry practice. Barrier locations have been identified (when required) based on guidance presented in AT&T's RF Exposure: Responsibilities, Procedures & Guidelines document, dated October 28, 20/4.

• Yellow CAUTION 2B sign posted at the base of the faux water tank near the climbing ladder.
The signage proposed for installation at this site complies with AT&T's RF Exposure: Responsibilities, Procedures & Guidelines document and therefore complies with FCC and OSHA requirements. Barriers are not recommended on this site. To reduce the risk of exposure and/or injury, EBl recommends that access to the faux water tank or areas associated with the active antenna installation be restricted anc secured where possible. More detailed information concerning site compliance recommendations is presented in Section 4.0 and Appendix B of this report.

1.0 FEDERAL COMMUNICATIONS COMMISSION (FCC) REQUIREMENTS The FCC has established Maximum Permissible Exposure (MPE) limits for human exposure to Radiofrequency Electromagnetic (RF-EME) energy fields, based on exposure limits recommended by the National Council on Radiation Protection and Measurements (NCRP) and, over a wide range of frequencies, the exposure limits developed by the Institute of Electrical and Electronics Engineers, Inc (IEEE) and adopted by the American National Standards Institute (ANSI) to replace the 1982 ANSI guidelines. Limits for localized absorption are based on recommendations of both ANSI/IEEE and NCRP.
The FCC guidelines incorporate two separate tiers of exposure limits that are based upon occupational/controlled exposure limits (for workers) and general public/uncontrolled exposure limits for members of the general public.
Occupationallcontrolled exposure limits apply to situations in which persons are exposed as a consequence of their employment and in which those persons who are exposed have been made fully aware of the potential for exposure and can exercise control over their exposure. Occupational/ controlled exposure limits also apply where exposure is of a transient nature as a result of incidental passage through a location where exposure levels may be above general public/uncontrolled limits (see below), as long as the exposed person has been made fully aware of the potential for exposure and can exercise control over his or her exposure by leaving the area or by some other appropriate means.
General public/uncontrolled exposure limits apply to situations in which the general public may be exposed or in which persons who are exposed as a consequence of their employment may not be made fully aware of the potential for exposure or cannot exercise control over their exposure. Therefore, members of the general public would always be considered under this category when exposure is not employment-related, for example, in the case of a telecommunications tower that exposes persons in a nearby residential area.
Table | and Figure I (below), which are included within the FCC's OET Bulletin 65, summarize the MPE limits for RF emissions. These limits are designed to provide a substantial margin of safety. They vary by frequency to take into account the different types of equipment that may be in operation at a particular facility and are "time-averaged" limits to reflect different durations resulting from controlled and uncontrolled exposures.
The FCC's MPEs are measured in terms of power (mW) over a unit surface area (cm2). Known as the power density, the FCC has established an occupational MPE of 5 milliwatts per square centimeter (mW/cm?) and an uncontrolled MPE of | mW/cm2 for equipment operating in the 1900 MHz frequency range. For the AT&T equipment operating at 850 MHz, the FCC's occupational MPE is 2.83 mW/cm? and an uncontrolled MPE of 0.57 mW/cm?. For the AT&T equipment operating at 700 MHz, the FCC's occupational MPE is 2.33 mW/cm? and an uncontrolled MPE of 0.47 mW/cm?. These limits are considered protective of these populations.

RF-EME Compliance Report
EBI Project No. 6220005716 15421 N 9th Street, Patterson, California Personal Communication (PCS) facilities used by AT&T in this area operate within a frequency range of 700-1900 MHz. Facilities typically consist of: I) electronic transceivers (the radios or cabinets) connected to wired telephone lines; and 2) antennas that send the wireless signals created by the transceivers to be received by individual subscriber units (PCS telephones). Transceivers are typically connected to antennas by coaxial cables.
Because of the short wavelength of PCS services, the antennas require line-of-site paths for good propagation, and are typically installed above ground level. Antennas are constructed to concentrate energy towards the horizon, with as little energy as possible scattered towards the ground or the sky.
This design, combined with the low power of PCS facilities, generally results in no possibility for exposure to approach Maximum Permissible Exposure (MPE) levels, with the exception of areas directly in front of the antennas.
2.0 AT&T RF EXPOSURE POLICY REQUIREMENTS
AT&T's RF Exposure: Responsibilities, Procedures & Guidelines document, dated October 28, 2014, requires that:
I. All sites must be analyzed for RF exposure compliance;
2. All sites must have that analysis documented; and
3. All sites must have any necessary signage and barriers installed.
Pursuant to this guidance, worst-case predictive modeling was performed for the site. This modeling is described below in Section 3.0. Lastly, based on the modeling and survey data, EBl has produced a Compliance Plan for this site that outlines the recommended signage and barriers. The recommended Compliance Plan for this site is described in Section 4.0.
3.0 WORST-CASE PREDICTIVE MODELING
In accordance with AT&T's RF Exposure policy, EBl performed theoretical modeling using RoofMaster ™ communications services. Using the computational methods set forth in Federal Communications (FCC) Office of Engineering & Technology (OET) Bulletin 65, "Evaluating Compliance with FCC Guidelines for predicted power density in a scalable grid based on the contributions of all RF sources characterized in the study scenario. At each grid location, the cumulative power density is expressed as a percentage of the FCC limits. Manufacturer antenna pattern data is utilized in these calculations. RoofMaster T models consist of the Far Field model as specified in OET-65 and an implementation of the OET-65 Cylindrical Model (Sula9). The models utilize several operational specifications for different types of antennas to produce a plot of spatially-averaged power densities that can be expressed as a percentage of the applicable exposure limit.
For this report, EBl utilized antenna and power data provided by AT&T and compared the resultant worst-case MPE levels to the FCC's occupational/controlled exposure limits outlined in OET Bulletin 65.
The assumptions used in the modeling are based upon information provided by AT&T and information gathered from other sources. There are no other wireless carriers with equipment installed at this site.
Based on worst-case predictive modeling, there are no modeled exposures on any accessible ground walking/working surface related to ATT's proposed antennas that exceed the FCC's occupational and/or general public exposure limits at this site.
EBI Consulting • 21 B Street • Burlington, MA 01803 • 1.800.786.2346 RF-EME Compliance Report USID No. 294157 Site No. CVL0I687 EBI Project No. 6220005716 1542| N 9th Street, Patterson, California At the nearest walking/working surfaces to the AT&T antennas on the ground, the maximum power density generated by the AT&T antennas is approximately 0.34 percent of the FCC's general public limit (0.07 percent of the FCC's occupational limit). The composite exposure level from all carriers on this site is approximately 0.34 percent of the FCC's general public limit (0.07 percent of the FCC's occupational limit) at the nearest walking/working surface to each antenna.
A graphical representation of the RoofMaster ™ modeling results is presented in Appendix B.
Microwave dish antennas are designed for point-to-point operations at the elevations of the installed equipment rather than ground-level coverage. Based on AT&T's RF Exposure: Responsibilities, Procedures & Guidelines document, dated October 28, 2014, microwave antennas are considered compliant if they are higher than 20 feet above any accessible walking/working surface. There are no microwaves installed at this site.

5.0 SUMMARY AND CONCLUSIONS
EBl has prepared this Radiofrequency Emissions Compliance Report for the proposed AT&T telecommunications equipment at the site located at 1542l N 9th Street in Patterson, California.
EBI has conducted theoretical modeling to estimate the worst-case power density from AT&T antennas to document potential MPE levels at this location and ensure that site control measures are adequate to meet FCC and OSHA requirements, as well as AT&T's corporate RF safety policies. As presented in the preceding sections, based on worst-case predictive modeling, there are no modeled exposures on any accessible ground walking/working surface related to ATT's proposed antennas that exceed the FCC's occupational and/or general public exposure limits at this site.
To reduce the risk of exposure and/or injury, EBl recommends that access to the faux water tank or areas associated with the active antenna installation be restricted and secured where possible. Signage is -ecommended at the site as presented in Section 4.0 and Appendix B. Posting of the signage brings the site into compliance with FCC rules and regulations and AT&T's corporate RF safety policies.

Introduction
AT&T Mobility is seeking to improve communications services to residences, businesses, public services, and area travelers in the City of Patterson, California. AT&T maintains a strong customer base in Patterson and constantly strives to improve coverage for both existing and potential customers. This project will expand AT&T's existing network and improve call quality, signal strength, and wireless connection services within both the City and the County, benefitting residents, travelers, public services, and roadway safety in the area.

Facility Design and Description
AT&T Mobility proposes the installation of a new wireless communications facility at the above-referenced address in order to improve coverage and capacity of the existing AT&T network. The facility has been designed as an 84.9' tall stealth bell tower, which will serve to provide AT&T with the necessary antenna centerline of 74' while also screening the antennas from public view. The tower, along with all of the necessary ground equipment, will be placed within a 30' × 30' ground lease area and surrounded by a 6' CMU wall with a 12' wide corrugated steel access gate.
Details of the site layout include:
• A 30' x 30' lease area enclosing:
• An 84.9' faux bell tower with antennas mounted at a centerline of 74'. • 1 walk-in equipment cabinet
• 130kw standby diesel generator with a 190 gallon fuel tank • A 6' CMU wall with a 12' corrugated steel access gate.
Please see the attached site plans, elevations and photosimulations for further information regarding the layout and nature of the proposed facility.
Location Selection and Need for Facility
AT&T seeks to improve wireless communication services in the City of Patterson and greater Stanislaus County. Presently, the targeted area of southern Patterson suffers from poor wireless coverage and low capacity levels, which can cause lack of overall network connectivity, recurring lost calls and ineffective service. The need for this proposed facility is due to complaints from AT&T customers, business, and travelers in this area. To remedy these problems, AT&T proposes this facility, which will bring improved service and capacity coverage to AT&T subscribers and emergency services in the area, as well as close the significant gap in coverage that currently exists.
Below, please see the comparison of the two maps. The first map shows the target area currently lacking wireless coverage on the AT&T network. The second map shows what the coverage will be like upon activation of the proposed facility. Please note that a significant geographic area without any indoor or transit coverage will receive significantly improved coverage following activation of the proposed facility within the targeted coverage area.

Findings
1. The requested Conditional Use is Consistent with the City of Paterson General Plan and Zoning Ordinance:
The City's General Plan provides a vision for Patterson's future, and this vision encompasses large scale residential and economic development due in significant part to "spill-over" from Bay Area expansion. It is inarguable that wireless infrastructure is a necessary and integral part of everyday life in today's day and age, and will continue to be for any contemplated future growth.
Additionally, this is a stealth facility, and while AT&T is seeking to exceed the overall height limit of the underlying zone in order to reach the necessary antenna centerline, the facility has been designed to comply with all other facets of the City of Patterson's Municipal Code.
2. The establishment, maintenance, or operation of the proposed use or structure will conform to the requirements and the intent of this title; and that such proposed use or structure will not, under the circumstances of the particular case or as conditioned, be injurious or detrimental to the health, safety, or general welfare of persons or property in the vicinity of the proposed use, or to the general welfare of the City:
This proposal will conform for all requirements of this title, and will at all times comply with all local, state and federal design, construction and safety standards.
Safety Benefits of Improved Wireless Service
AT&T offers its customers multiple services such as voice calls, text messaging, mobile email, picture/video messaging, mobile web, navigation, broadband access, V CAST, and E911 services. Mobile phone use has become an extremely important tool for first responders and serves as a back-up system in the event of a natural disaster.
Operations & Maintenance
The site is unmanned and requires no on-site personnel. Visitation to the site by a service technician for routine maintenance may occur up to once per week. The proposed site is entirely self-monitored and connected directly to a central office where sophisticated computers alert personnel to any equipment malfunction. Because the wireless facility is unmanned, there are no regular hours of operation and no impacts to existing local traffic patterns. No water or sanitation services will be required
Compliance with FCC Standards
AT&T Wireless complies with all FCC rules governing construction requirements, technical standards, interference protection, power and height limitations and radio frequency standards. An RF report has been prepared by independent licensed engineering firm Hammett & Edison, Inc., demonstrating that the ATT facility has been designed to, comply with FCC requirements. In addition, AT&T complies with all FAA rules on site location and operation.
Notice of Actions Affecting This Development Permit
In accordance with California Government Code Section 65945(a), AT&T Mobility requests notice of any proposal to adopt or amend the: general plan, specific plan, zoning ordinance, ordinance(s) affecting building or grading permits that would in any manner affect this development permit. Any such notice may be sent to 2009 V Street, Sacramento, CA 95818.

COMMENTS TO REQUEST FOR REVIEW FOR THE NEGATIVE DECLARATION, AT&T WIRELESS TOWER - CENTENNIAL PARK PROJECT, SCH#2021110279,
STANISLAUS COUNTY
Pursuant to the State Clearinghouse's 18 November 2021 request, the Central Valley Regional Water Quality Control Board (Central Valley Water Board) has reviewed the Request for Review for the Negative Declaration for the AT&T Wireless Tower - Centennial Park Project, located in Stanislaus County.
Our agency is delegated with the responsibility of protecting the quality of surface and groundwaters of the state; therefore our comments will address concerns surrounding those issues.
I. Regulatory Setting
Basin Plan
The Central Valley Water Board is required to formulate and adopt Basin Plans for all areas within the Central Valley region under Section 13240 of the Porter-Cologne Water Quality Control Act. Each Basin Plan must contain water quality objectives to ensure the reasonable protection of beneficial uses, as well as a program of implementation for achieving water quality objectives with the Basin Plans. Federal regulations require each state to adopt water quality standards to protect the public health or welfare, enhance the quality of water and serve the purposes of the Clean Water Act. In California, the beneficial uses, water quality objectives, and the Antidegradation Policy are the State's water quality standards. Water quality standards are also contained in the National Toxics Rule, 40 CFR Section 131.36, and the California Toxics Rule, 40 CFR Section 131.38.
The Basin Plan is subject to modification as necessary, considering applicable laws, policies, technologies, water quality conditions and priorities. The original Basin Plans were adopted in 1975, and have been updated and revised periodically as required, using Basin Plan amendments. Once the Central Valley Water Board has adopted a Basin Plan amendment in noticed public hearings, it must be approved by the State Water Resources Control Board (State Water Board), Office of Administrative Law (OAL) and in some cases, the United States Environmental DENISE KADARA, ACTING CHAIR | PATRICK PULUPA, EXECUTIVE OFFICER 11020 Sun Center Drive #200, Rancho Cordova, CA 95670 | www.waterboards.ca.gov/centralvalley AT&T Wireless Tower - 2- 20 December 2021
- Centennial Park Project
Stanislaus County
Protection Agency (USEPA). Basin Plan amendments only become effective after they have been approved by the OAL and in some cases, the USEPA. Every three (3) years, a review of the Basin Plan is completed that assesses the appropriateness of existing standards and evaluates and prioritizes Basin Planning issues. For more information on the Water Quality Control Plan for the Sacramento and San Joaquin River Basins, please visit our website:
http://www.waterboards.ca.gov/centralvalley/water issues/basin plans/ Antidegradation Considerations
All wastewater discharges must comply with the Antidegradation Policy (State Water Board Resolution 68-16) and the Antidegradation Implementation Policy contained in the Basin Plan. The Antidegradation Implementation Policy is available on page 74 https://www.waterboards.ca.gov/centralvalley/water issues/basin plans/sacsir 2018 In part it states:
Any discharge of waste to high quality waters must apply best practicable treatment or control not only to prevent a condition of pollution or nuisance from occurring, but also to maintain the highest water quality possible consistent with the maximum benefit to the people of the State.
This information must be presented as an analysis of the impacts and potential impacts of the discharge on water quality, as measured by background concentrations and applicable water quality objectives.
The antidegradation analysis is a mandatory element in the National Pollutant Discharge Elimination System and land discharge Waste Discharge Requirements (WDRs) permitting processes. The environmental review document should evaluate potential impacts to both surface and groundwater quality.
Il. Permitting Requirements
Construction Storm Water General Permit
Dischargers whose project disturb one or more acres of soil or where projects disturb less than one acre but are part of a larger common plan of development that in total disturbs one or more acres, are required to obtain coverage under the General Permit for Storm Water Discharges Associated with Construction and Land Disturbance Activities (Construction General Permit), Construction General Permit Order No. 2009-0009-DWQ. Construction activity subject to this permit includes clearing, grading, grubbing, disturbances to the ground, such as stockpiling, or excavation, but does not include regular maintenance activities performed to restore the original line, grade, or capacity of the facility. The Construction General Permit requires the development and implementation of a Storm Water Pollution Prevention Plan (SWPPP). For more information on the Construction General Permit, visit the State Water Resources Control Board website at:
http://www.waterboards.ca.gov/water issues/programs/stormwater/constpermits.sht ml

Stanislaus County
Industrial Storm Water General Permit
Storm water discharges associated with industrial sites must comply with the regulations contained in the Industrial Storm Water General Permit Order No. 2014- 0057-DWQ. For more information on the Industrial Storm Water General Permit, visit the Central Valley Water Board website at:
http://www.waterboards.ca.gov/centralvalley/water issues/storm water/industrial ge neral permits/index.shtml
Clean Water Act Section 404 Permit
If the project will involve the discharge of dredged or fill material in navigable waters or wetlands, a permit pursuant to Section 404 of the Clean Water Act may be needed from the United States Army Corps of Engineers (USACE). If a Section 40 ermit is required by the USACE, the Central Valley Water Board will review the permit application to ensure that discharge will not violate water quality standards. If the project requires surface water drainage realignment, the applicant is advised to contact the Department of Fish and Game for information on Streambed Alteration Permit requirements. If you have any questions regarding the Clean Water Act Section 404 permits, please contact the Regulatory Division of the Sacramento District of USACE at (916) 557-5250.
Clean Water Act Section 401 Permit - Water Quality Certification If an USACE permit (e.g., Non-Reporting Nationwide Permit, Nationwide Permit, Letter of Permission, Individual Permit, Regional General Permit, Programmatic General Permit), or any other federal permit (e.g., Section 10 of the Rivers and Harbors Act or Section 9 from the United States Coast Guard), is required for this project due to the disturbance of waters of the United States (such as streams and wetlands), then a Water Quality Certification must be obtained from the Central Valley Water Board prior to initiation of project activities. There are no waivers for 401 Water Quality Certifications. For more information on the Water Quality Certification, visit the Central Valley Water Board website at:
https://www.waterboards.ca.gov/centralvalley/water issues/water quality certificatio n/
Waste Discharge Requirements - Discharges to Waters of the State If USACE determines that only non-jurisdictional waters of the State (i.e., "non- federal" waters of the State) are present in the proposed project area, the proposed project may require a Waste Discharge Requirement (WDR) permit to be issued by Central Valley Water Board. Under the California Porter-Cologne Water Quality Control Act, discharges to all waters of the State, including all wetlands and other waters of the State including, but not limited to, isolated wetlands, are subject to State regulation. For more information on the Waste Discharges to Surface Water NDES Program and WDR processes, visit the Central Valley Water Board website at: https://www.waterboards.ca.gov/centralvalley/water issues/waste to surface wat er/
