(1) Activities conducted in public parks,public playgrounds, and public or private school grounds, including but not limited to school athletic and school entertainment events; (2) Any mechanical device, apparatus,or equipment used,related to,or connected with, emergency activities or emergency work; (3) Noise sources associated with construction,provided such activities do not take place before 6:00 a.m. or after 9:00 p.m. on any day; (4) Noise sources associated with the maintenance of residential property located in a residential zone, provided such activities shall take place between the hours of 8:00 a.m. and 9:00 p.m. on any day; (5) Noise sources emanating from any agricultural operation, including activities associated with the processing or transportation of crops when such activities are conducted on agriculturally zoned lands; (6) Noise sources associated with residential air conditioning equipment,provided such equipment is in good repair; (7) Noise sources associated with work performed by private or public utilities in the maintenance or modification of its facilities; (8) Noise sources associated with the collection of waste or garbage; (9) Any activity whose regulation has been preempted by state or federal law. (d) Acoustical Study.The Review Authority shall require the preparation of an acoustical study in instances where it has [been] determined that a project may expose existing or proposed noise sensitive land uses to noise levels exceeding the noise standards specified in Table 9-1025.9 (Table 4.4-5). This determination shall be based on the existing or future sixty-five(65) dB L&noise contour in the General Plan,the proximity of new noise sensitive land uses to known noise sources, or the knowledge that a potential for adverse noise impacts exists. The study shall be paid for by the applicant and shall be prepared by a person or persons selected by the Director. The Director shall select the consultant from the County's consultant list. The acoustical study shall include the following information: (1) A general description of the project,with appropriate maps, and the noise sources of concern; (2) description of the methodology that will be used to assess noise impacts, including a listing of all assumptions and data used in any computer models. (A)Computer models that will be used for noise predictions shall be standard versions approved by the FHWA,FAA(Federal Aviation Administration), Caltrans,or other government agencies. (B) For traffic noise studies,the computer models, SOUND32 or other proprietary models based on the 1978 "FHWA Highway Traffic Noise Prediction Model(FHWA-RD-77-108)" shall be used. The FHWA's new"Traffic Noise Model"(TNM) shall be used after its phase-in date. For aircraft noise studies,the latest version of the FAA's"Integrated Noise Model(INM)" shall be used.
