This Noise Study includes a discussion of applicable regulatory criteria, measured ambient sound levels, predicted sound levels at adjacent property lines, and assessment of compliance with codified sound level limits. SUMMARY Based on the analysis outlined in this report, no noise mitigation is required to comply with codified sound level limits. NOMENCLATURE Decibel The auditory response to sound is a complex process that occurs over a wide range of frequencies and intensities. Decibel levels, or "dB," are a form of shorthand that compresses this broad range of intensities with a convenient numerical scale. The decibel scale is logarithmic. For example, using the decibel scale, a doubling or halving of energy causes the sound level to change by 3 dB; it does not double or halve the sound loudness as might be expected. The minimum sound level variation perceptible to a human observer is generally around 3- dB. A 5-dB change is clearly perceptible, and an 8 to 10 dB change is associated with a perceived doubling or halving of loudness. The human ear has a unique response to sound pressure. lt is less sensitive to those sounds falling outside the speech frequency range. Sound level meters and monitors utilize a filtering system to approximate human perception of sound. Measurements made utilizing this filtering system are referred to as "A weighted" and are called "dBA'. Common sound"pressure levels are reported below in Table 1.

Metrics Sound Pressure Level, SPL Sound pressure level correlates with what is heard by the human ear. SPL is defined as the squared ratio of the sound pressure with reference to 20 pPa. Sound pressure is affected by distance, path, barriers, directivity, etc. Sound Power Level, L*A Sound power is the amount of energy per second generated by a source, measured in watts. The sound power level (L*A) is a decibel representation with a reference value of 1 pico-watt (pW). Sound power is independent of distance, path, or influence from any nearby surfaces.

Review of audio files collected during the measurements indicate that traffic remained the dominant sound source throughout the measurement period. Other sound sources included aircraft noise, birds, and other nature sounds. ACOUSTICAL MODEL The primary tool used to predict sound levels at neighboring property lines from the proposed mechanical equipment was a 3-D computer noise model. Cadna/A 3-D Noise Model The computer noise model uses the acoustic modeling software Cadna/A. Cadna/A utilizes the CADNA (Control of Accuracy and Debugging for Numerical Applications) computation engine developed by the Pierre et Marie Curie Universig of Paris. The model uses the lnternational Organization for Standardization 9613 Part ll algorithms, implemented in the Cadna/A software, which accounts for the effects of distance, topography, and surface reflections on sound levels. Model Development The locations of the buildings were determined from drawings provided to our office by Outback Bud Company.

These predicted sound levels do not include contributions from the existing or future ambient noise environment. Table 7. Predicted Sound Levels at Pro dBA As shown in Table 7, predicted sound levels produced by the proposed mechanical equipment comply with daytime and nighttime codified sound levels. ln order to determine the "impact" to the community, this analysis relies on guidelines presented in the EPA Region X document entitled "Environmental lmpact Statement Guidelines" (EPS Region X, 1973.) ln the published document, increases in noise are discussed in relation to expected community response to the introduced noise source. The responses are described as follows: . Up to 5 dB increase - few complaints if gradual increase. 5 to 10 dB increase - more complaints, especially during sleeping hours. Over 10 dB increase - substantial number of complaints Generally, no mitigation is recommended if the increase is less than 5 dB. Some mitigation should be considered for increases of 5 to 10 dB. lncreases greater than 10 dB would be considered serious and would warrant close attention. The EPA guidelines are not standards and do not have the force of law but do serve as useful indicators for potential noise impacts of projects undergoing evaluation. The anticipated increases to the existing ambient sound environment are shown in Table 8. As shown in Table I sound level near the measurement location are anticipated to increase.

MLA1 8.OO I 02 NOISE REPORT 1 Noise Report and Analysis Property Location: 860 Old Coyle Road Jessie Williamson [tt- A L B- oo LoL zoyw -060 77 FEB 2 7 20t9 JEFFERSON COUNTYDCD 2 Abstract 1no This report covers the proposed Cannabis producing and processing located on Ef€€{d Road and its projected noise levels. Included in the report will be the equipment used in the building. The equipment used and the disciple levels produced will be compared to the Environmental Protection Agency (EPA) Region 10 Noise Program, it will determine the impact on the community. J Noise Report and Analysis Existing and Anticipated Land Uses Near Site Zorung of the proposed project on 860 Old Coyle Road Quilcene, WA is rural residential. It is an ideal location due to the low impact it will have on the surrounding areas. The site borders two undeveloped lots on parallel sides. The back side of the property borders commercial forest land while the front of the property borders Coyle Road. There are no established residences bordering the 5.48-acre parcel that the proposed building would be on. Across the road on Blueberry Hill there are a few residences. The general area is sparse with residential homes, a large quantity of land in this area is commercial forestry. Existing Noise Levels The property is 5.48 acres of undeveloped land and the majority of surrounding are4 including all land bordering the site is undeveloped forested land. The forest and vegetation act as a natural sound buffer and disrupt the sound waves. Coyle Road provides most of the sound, from occasional cars passing. Coyle Road is the main road out on the Tornados Peninsula. When logging occurs, the sound levels increase due to trees falling, chainsaws, and log trucks hauling the trees. The average chainsaw is 120 dB. Anticipated Noise Levels Each building will have two fans, one intake and one exhaust. The fans will be located on either side of the building, allowing the air from one side to be pulled in and circulated through the building and exit through the exhaust fan. There will be two 24" ES Shutter fan, (HI 5,850 cfm/ LOW 3475 cfm), one on each end of the building. The noise of these fans is HI60 dB/ LOW 55 dB (J&D). When the second building is constructed, it will have the same design. Each 4 exhaust system is managed using an electronic environmental controller. The fans will circulate the air in the building for about an hour every morning. Noise and sound studies vary depending on where and who is collecting the data. A decibel is defined as "a unit used to measure the intensity of a sound or the power level of an electrical signal by comparing it with a given level on a logarithmic scale" (Webster). To give a reference of what decibel relate to here are a few examples l0 dB is normal breathing, 50 dB is average home noises, 60 dB is conversational speech, and 110 dB is a baby crying. To see more decibels and what they relate to see figure 1. EPA Regulations The Environmental Protection Agency (EPA) was established to ensure that all Americans can operate free from noise that adversely affects their welfare and health. EPA Region I0 Noise Guidelines for Environmental Impact Statement have deJined the of "impact" as below(airconco): - 0-5 dB (A) inuease is considered slight impact -5-10 dB (A) increase is considered significant impact -Over l0 dB (A) increase is considered very serious impact Noise Abatement Noise abatement is used to reduce the noise and vibration from a given source. There are many ways that noise abatement can be put into action. We plan on keeping a natural vegetation buffer 43" in front of the property and25" from all other sides. The natural foliage will help absorb the sound. The fans we will purchase will also be designed with quiet technology and will not exceed the established limits. 5 Conclusion In conclusion, our fans will not be a nuisance or disrupt the community. We plan on blending into the surroundings and only using our fans in the momings to circulate air. When construction is finishedo we will reassess our sound and take further action. The fans we are looking to install on HI only emit 60dB. The principle of sound says that as the distance increases from the source, the amount of area covered by the sound waves increases. This means that the same amount of energy is spread over a greater urea, so the loudness and intensity of the sound is less. Between the principal of sound, quiet fan technology, and our noise abatement there will be no impact on the surrounding community. 6 Refrences hups ://www.airconco.com/info graphic/decibel-scale/ http://wwwairdistributor.neVimages/pdfl/o2Ofiles/InOutESshutterWcord.pdf https ://www.merriam-webster. com/dictionary/decibel 7 Sound Level Change Relative to Loudness Sound Level Change Acoustic Energy Loss Relative Loudness 0 dB 0 Reference -3 dB 50o/o Perceptible Change -10 dB 90o/o Half as Loud -20 dB 99%1/4 as Loud -30 dB 99.9%1/8 as Loud -40 dB 99.99%1/16 as Loud 8 Figure 1 Decibel Noise Source Decibel Effect Level Jet take-off (at 25 meters) Recommended product Outdoor Noise Barriers 150 Eardrum ruplure Thunderclap, chain saw.
