<br />tX{C/'IL 1 ,_ C~ <br /> <br />~~n <br /> <br /> <br />August 27, 1993 <br /> <br />Mr. Thomas Muller <br />Chief Executive Officer <br />Advanced Circuits, Inc. <br />15102 Minnetonka Industrial Boulevard <br />Minnetonka, MN 55345 <br /> <br />Dear Tom: <br /> <br />SUBJECT: ACI--ROSEVILLE PLANT NOISE REDUCTION PROGRAM <br /> <br />As you know, the City of Roseville and ACI have been working for <br />over two years on some of the noise problems affecting the <br />residential area to the north of your facility. We appreciate the <br />efforts of your firm to address these concerns, and particularly <br />the response by Dan McCarthy of your staff. However, nearby <br />residents are still being impacted by the noise from your facility <br />and other commercial and industrial properties in the vicinity. <br /> <br />On August 16, the Roseville City Council reviewed the noise <br />reduction plans for your manufacturing buildings located at 1633 <br />and 1725 Terrace Drive. The City Council asked that I meet with <br />you to clarify that the noise reduction program must be <br />accomplished prior to and as a condition of the city's issuance of <br />a Certificate of Occupancy on your new building addition. The <br />primary goal is to contain noise to a level of 50 decibels as <br />heard from the area to the north, and to eliminate objectionable <br />intermittent noises. <br /> <br />The sound consultant jointly engaged by ACI and the City, David <br />Breslau, has recommended the following noise attenuation efforts: <br /> <br />1. New sound baffles and shields will be installed on all <br />equipment with a sound level over 50 decibels to meet the <br />State and City noise standards. A plan for these improvements <br />has been worked on cooperatively by Mr. Breslau and ACI Plant <br />Manager Dan McCarthy. The construction of these improvements <br />is underway. <br /> <br />2. ACI and Dan McCarthy will work with their staff to reduce <br />noise from the doors and overhead garage doors being left <br />open. <br /> <br />2(,()O CIYIC CE:\TER DRIYE · ROSE\-ILLE · ~lI:\:\ESOT.\ · 5511.1-1H99 <br />612--!90-22()O · F.\..~ ()12--!9U-22iO <br />
