(Wood), has prepared this Project Description and Justification letter on behalf of Ford Motor Company (Ford) for the Bayridge Park Homeowners Association (HOA; also known as Parcel 10), located in Newport Beach, California, in support of an application for a Limited Term Permit. This letter describes and justifies a project to remediate volatile organic compounds (VOCs) vapors present in the soil below residential homes in Parcel 10. Parcel 10 is adjacent to and north of the Former Ford Aeronutronics Facility (Former Facility). The project location is shown on Figures 1 and 2. The VOCs in soil vapor are believed to be related to historic operations at the Former Facility. Wood is the environmental consultant working on behalf of Ford on the design and implementation of the project. The lead regulatory agency for the Former Facility and related off-site areas is the Santa Ana Regional Water Quality Control Board (Water Board). The design of a soil vapor extraction system to remediate the soil is described in a Remedial Design and Implementation Plan (RDIP) which was approved by the Water Board on January 28, 2022. The system consists of vapor extraction wells, piping, and a treatment system housed in a prefabricated building with a floor area of 240 square feet. Using a vacuum pump (also known as a “blower”), the treatment system will extract vapor from soil through the wells and deliver it to the treatment system where granular activated carbon removes the VOCs and then clean vapor is discharged to the Wood Environment & Infrastructure Solutions, Inc. 555 12th Street, Suite 215 Oakland, California 94607 USA T: 1-510-663-4100 F: 1-833-778-3465 www.woodplc.com PA2022-0180 Makana Nova Community Development Department August 10, 2022 Page 2 atmosphere under a permit to be obtained from the South Coast Air Quality Management District. The soil vapor extraction and treatment system will be operational until the concentrations of VOCs in soil reach target remedial objectives, at which time the treatment system will be removed. The RDIP is available through the Water Resources Control Boar’s GeoTracker system website at: https://documents.geotracker.waterboards.ca.gov/esi/uploads/geo_report/4708529472/SL188023848.PDF All documents related to the site are available on GeoTracker at the following address: https://geotracker.waterboards.ca.gov/profile_report.asp?global_id=SL188023848 During the first half of 2022, Wood finalized the design of the system which consists of 13 soil vapor extraction wells, 2,400 feet of piping, and the treatment system. The layout of the system is shown in Figure 3. Selected engineering drawings (Drawings) showing the overall system and the treatment system site are included in Attachment 1. As a result of discussions in late 2021 and early 2022 with the Bayridge Park HOA and Makana Nova, of the Planning Division of the City’s Community Development Department, it was agreed that the best location for the treatment system building would be within the Parcel 10 property boundary but outside of the residential area, as shown on Figure 4 and on the Drawings. This was identified as the most feasible location given the steep hillside and landscaping to the north and south, and the HOA’s desire for the system to be visually hidden from residents’ sight as much as possible. To help blend into the surroundings, the treatment system building, measuring 20 feet long by 12 feet wide by 10 feet high, will be clad in siding matching the surrounding buildings. Elevations of the building are shown on Drawing C-4. On completion of the building, landscaping will be restored around it and will provide further screening. Since the proposed building is closer to the residence at 94 Hartford Drive than the City’s allowable structure separation of 8-feet, a Variance to the Community District Regulations1 is required. In early July 2022, Makana Nova recommended that Wood apply for a Limited Term Permit since the treatment system building is a temporary structure. If the system is expected to operate past the expiration of the Limited Term Permit, Wood will apply for a Variance. The City has requested that the project team prepare an acoustic evaluation of the treatment system to demonstrate that the noise it produces will not impact nearby residents. This is presented as Attachment 2. The conclusion is that the system will not produce noise greater than 50 dB at a distance of 3-feet from the building. This approximates to the sound produced by a refrigerator. The City’s Exterior Noise Standards requires that the exterior sound in a Zone I – Single, two-or multiple family residential type of land use shall not exceed an Allowable Exterior Noise Level (Equivalent Noise Level, Leq) of 55 decibels (dB) between 7 a.m. to 10 p.m. and 50 dB between 10 p.m. and 7 a.m. The treatment system will therefore comply with the Exterior Noise Standards. In summary, the Water Board has mandated the construction and operation of the proposed SVE system because it is 1 See Aeronautic Ford, Planned Community District Regulations, Amendment No. 2006-004(PA2006-173) PA2022-0180 Makana Nova Community Development Department August 10, 2022 Page 3 important to the protection of human and environmental health, and the project is consequently requesting the granting of a Limited Term Permit.

The remediation is approved by the Santa Ana Regional Water Board. As part of the permitting process for the project, the City of Newport Beach (the City) has requested the project apply for a Limited Term Permit. The objective of this document is to demonstrate how the treatment system equipment which is part of the project will comply with the City’s noise regulations. PROJECT BACKGROUND The SVE system will consist of 13 vapor extraction wells, 2500 feet of piping, and a soil vapor treatment system that will suck vapor from the soil and treat it through carbon vessels. The layout of the system is shown on Figure 1. The remediated vapor will be discharged under a permit to be issued by the South Coast Air Quality Management District. The treatment system will be housed in a prefabricated building which will measure be 20-feet by 12-feet (240 square feet), by 10-feet high. Its location is shown on Figure 2. One corner will sit 1.5-feet from the exterior of the property at 94 Hartford Drive. The treatment system and building will be delivered to the site as a single unit and anchored to a concrete slab to be constructed as part of the project. In the following sections we describe how an Acoustic Audit will be conducted to ensure compliance. OVERVIEW OF CITY NOISE REGULATIONS The City’s noise regulations are codified in Chapter 10.26 – Community Noise Control of the Municipal Code.https://www.codepublishing.com/CA/NewportBeach/#!/NewportBeach10/NewportBeach1026.ht PA2022-0180 Makana Nova Community Development Department August 10, 2022 Page 2 ml#10.26 Section 10.26.025, Exterior Noise Standards requires that the exterior sound in a Zone I – Single, two-or multiple family residential type of land use shall not exceed an Allowable Exterior Noise Level (Equivalent Noise Level, Leq) of 55 decibels (dB) between 7 a.m. to 10 p.m. and 50 dB between 10 p.m. and 7 a.m. TREATMENT SYSTEM NOISE CONTROL MEASURES The primary noise producing components of the treatment system are four “blowers” which generate the vacuum required by the soil vapor extraction system. The manufacturer’s specification for this blower is attached. According to this, the blower produces a consistent sound level of 74 dB. Note that four blowers together will not produce 4-times this noise level since decibels are not additive. The combined decibel level will be approximately 80 dB. The aim of noise control measures is to attenuate the blower noise to less than 50 dB at the exterior wall of 94 Hartford Drive, in accordance with the City’s Exterior Noise Standards. To achieve this the following elements the supplier of the system has incorporated the following elements into the design of the treatment system and building. • Selection of the quietest available blower, with integral silencers • Locating the blower on the opposite side of the building to the residence (see Figure 2) • Minimum R13 insulation plus 2-inches of sound foam on the walls and ceiling of the building • Spray-on sound foam insulation on the underside of the building • Hanging sound blankets in the interior of the building on critical sound areas for further damping The supplier has fabricated several similar systems which have complied with strict noise requirements. To demonstrate compliance with the City’s standards, Acoustic Audits will be performed. ACOUSTIC AUDIT An Acoustic Audit of the prefabricated building and treatment system unit will be conducted before leaving the factory in accordance with the City’s Equivalent noise level (Leq) requirement which involves measurement of a steady state noise level over 15 minutes. The unit will not be shipped from the factory until the 15-minute Leq is less than or equal to 50 dB. If required, additional sound reduction measures will be implemented to achieve the required level. Documentation of the Acoustic Audit can be provided to the City before startup of the treatment system. As a final confirmation, a second Acoustic Audit will be conducted after anchoring of the building and connection of permanent power. PA2022-0180 Makana Nova Community Development Department August 10, 2022 Page 3 It should be noted that the existing residential air conditioning unit adjacent to the treatment system may produce more noise, since the noise limit even for new AC system is 55 dB per the City’s noise ordinance. CONCLUSION It is our professional opinion that the treatment system equipment and enclosing building will be suitably engineered to reduce the emitted noise to less than 50 dB, in accordance with the City’s noise regulations. And this will be checked by a rigorous Acoustic Audit. Sincerely, Wood Environment & Infrastructure Solutions, Inc.
