EI maintains a team of experienced industrial hygienists available <br />to provide the scope and quality of services that you require. The following proposal details the needs, sampling <br />methodologies and costs for this noise monitoring project. <br />Statement of Need <br />It is our understanding that Orange County has identified periodic industrial hygiene monitoring needs <br />surrounding noise exposure with their grounds crew, specifically with mowers, blowers and edgers. Personal <br />noise dosimetry measurements are needed to document current exposures and advance the ongoing hearing <br />conservation program. <br />Proposed Scope of Work <br />1. An opening conference will be held with you or your appointed representative to discuss audit procedures <br />prior to the survey. <br />2. Up to five (5) personal samples will be collected to evaluate employee exposure to noise levels using <br />Casella CEL-35x personal noise dosimeters (or equivalent), which will be calibrated before and after use. <br />Noise samples will be evaluated for employees Time Weighted Average (TWA) noise exposure for <br />comparison with the OSHA Action Level (AL) of 85 dB(A) and Permissible Exposure Limit (PEL) of 90 <br />dB(A). <br />3. A closing conference will be held with management at the end of the workday in question to discuss the <br />initial survey findings and observations. <br />4. A detailed written report will be prepared addressing survey findings and will be submitted generally <br />within twenty-one (21) days of the survey date. As necessary, recommendations will be made to assist the <br />client in reducing ambient noise from the servers and to reduce employee exposures approaching or <br />exceeding OSHA Permissible Exposure Limits (PEL). <br />Methodology <br />An experienced EI Industrial Hygienist from our Morrisville, NC office will conduct the proposed <br />assessment/analysis under direct peer review of a board Certified Industrial Hygienist (CIH).
