The results of the sound testing found that the trash compactor is in full compliance with MPCA standards. However, the Generator exceeded noise standards at one monitoring point (east property line ). Lowe's is currently pursuing options to reduce the noise levels to be within the MPCA guidelines. One of the options proposed by the generator manufacturer is a Level i sound housing enclosure, however, the lead time for design fabrication and installation would be approximately 12 weeks. Several other options are also under consideration that would reduce the noise output, I expect Lowe's to finalize a sound reduction plan shortly and will send you an update as soon as this occurs, Feel free to give me a call with any questions or concerns you may have.

(Terracon) has completed a noise survey at the above referenced site. The purpose of this letter is to present the results of the noise survey. Project Information Terracon completed a noise survey at the request of Collins Electrical Construction Co, /convergent Media for an electrical generator and trash compactor located on the exterior of the Lowe's store in Oak Park Heights, Minnesota. The noise survey was conducted in general acco rdance with the Minnesota Pollution control Agency (MPGA) Noise Pollution Control Standards as set forth in Minnesota Rules Chapter 7030 and A Gtficle to Noise Coiitrof it) Minnesota issued by the MPcA and dated March 1999 (Noise Control uidance). The purpose of the survey was to measure the noise level created by a generator and trash compactor at a property adjacent and east of the site where residential town hornes are to he constructed. Noise Survey A Terracon representative conducted a brief survey of the propert adjacent to the site in order to select the most appropriate monitoring location, Based on a telephone conversation with Eric Joh of the City o f Oa k Park Heights, the monitoring loc -rations were tirnited t o points on the site property itself and not on adjacent propertie - -s. The Terracon representative selected two monitoring points on the property line of the site. Point 1 was located near the southwest corner of the property approximately 175 feet west and 35 feet south of the trash compactor. Point 1 was selected for its proximity to the trash compactor and for its distance f rom a harrier wall that has been erected on the southern property line. Point 2 was located on the eastern property line approximately 239 feet east and 59 feet south of the generator. Point 2 was selected for its proximity to the generator and an a djacent property tc 111e east that eventually support town homes. A sketch of the site and the monitoring points is provided can Delivering success tQr Clients and Employees Since 1965 4 of 25 Moro T han 80 office& nationwide Lo e' l oak Park Heights, MN Noise Survey Project # #41 067051 January 8, 2006 Irurracon the noise survey form attached. According to Minnesota Rules 7030,0050, the site has a Noise Area Classification (NAG) of 2 for retail trade facilities. Sound lev measurements were taken using a Quest 1200 sound level meter equipped with a wind screen attachment. The sound level meter was set to the "A" weighted scale used for measuring sounds wi thin the range of h uman hearing and all measurements were taken using the "FAST" response setting. The sound level meter was mounted on a tripod at a height of approximately 3.5 feet above the ground surface. Prior to conductir)g measurements, the sound level meter was calibrated using a calibration attachment. The calibration information was recorded on the attached noise survey fora. For the background noise level, several measurements were take over a period of 1 0 rninutes and averaged. The background noise level was estimated at approximately 50 decibels (dBA). Generator Monitoring Monitoring of the gener noise level was conducted for one hour monitoring points 1 and from 1:30 pr i to 3:30 pm. A sound level reading was made even 10 seconds during the hour for a total of 360 readings for each monitoring point, The sound levels were recorded on the manual rponitoring data sheet attached. A light breeze of approximately three to five miles per hour was observed from the north an the temperature was approximately 45 `)1 . Using the method described in the noise Control Guidance, the 10 "' and 50' percentile noise levels (L10 and t..50, respectively) were estimated using the results recorded on the attached manual monitoring data sheets, The L10 and 1...,50 for the generator at monitoring points and the noise standard for the NAC are listed below in Table 1 .

Terracon conducted measurements at monitoring points 1 and 2 while the trash compactor was operated once by itself and once while the generator was in operation. In each case, the compactor operated for approximately one minute, which allowed N - tiP 100)7 351 -BU'W fee) 0A dDO 2 . 5 of 25 Lowe's / Oak Park Heights, MN Noise Survey Project #41067051 January 8, 2806 1f"v i n for six measurements. No change in sound level was observed at the monitoring points while the trash compactor was operated at the same time as the generator; therefore the measu rements were not recorded, Table 2 below lists the measurements trade while only the trash compac operated, Because the sound level measurement varied by less than one dB during the compactor operation cycle at each monitoring point, only one measurement value is listed. The sound levels measured are shown on the attached manual monitoring sheets. Table 2 — Trash compact No ise Location 0onitoring Point 1 Vlonitoring Point 2 Sound Level 1 F c 54 Conclusions The L10 and 1-50 values from Table 1 and the measurements from Table 2 were compared to the noise standards in Minnesota RUIes 7030,0040 for NAC 2. The measurements f or the trash compactor at paints 1 and 2 listed in Table 2 did not exceed either the L10 or the L50 standard. The L10 and L50 values estitriated for the generator at point- 1 did riot exceed the NA 2 standards; however, both the L10 and L50 values estimated for the generator at point 2 exceeded the NAG 2 standards (See Table 1). Minnesota R ule 7030.0030 states that exceedances of noise standards for an NAC r not be violated upon establishment of land use within the NAC, Based on the noise s tandard exceedances observed at point 2 during operation of the generator, noise abatement measures may be necessary depending on the application of noise standards by the local municipal authority. The City of Oak Park heights should be consulted to determine if noise abatement measures should be implemented. S incerely, TERRACON J n U P, G, Environmental Scientist David J. Wol #gra�i�i, f',EE.
