Ex. E <br />3) Predicted Equipment Sound Levels <br />The proposed cell tower site has an equipment room filled with noise making communication <br />equipment. SSA noise report does not include how loud noise levels build up in the room and <br />how much noise leaks out of the equipment room. There is a second room earmarked for <br />additional future communication equipment and no evaluation of this second room has been <br />included in the SSA noise study. <br />To cool the first equipment room, two exterior wall mounted air conditioning units are installed <br />on the east end of the equipment room. No mention of cooling the second future equipment <br />room was made in SAS report. The air conditioners <br />To supply backup power, a motor/generator set will be installed on site, in a small room located <br />between the two communication equipment rooms. There will be large openings in the generator <br />room to allow for air exchange and the engine exhaust pipe will also emit noise to the outside. <br />The generator runs intermittently except for power outages. <br />The SSA report addresses the generator and the two air conditioners. It does not address the <br />noise made by the communication equipment nor does it address the impact made by adding <br />more communication equipment in the second communication equipment room. It does not <br />include the addition of a new pair of wall mounted air conditioners which would be needed to <br />cool down the second communication room. <br />A) 24-Hour Operation Equipment <br />There are two kinds of 24-Hour equipment used on site. The actual communication equipment is <br />housed in an equipment room which is located at the south east corner on the back side of the <br />church building. The noise buildup in this room is not discussed in the SSA report. The heat <br />buildup in this room is cooled by 2 wall mounted air conditioning systems, which comprise the <br />only 24-hour noise source for this proposed cell tower installation. <br />(a) Simultaneous Operation Oversight <br />operations so that both units get the same wear. SSA claims (top paragraph page 2) that this lead <br />lag system means that neither unit will run while the other is running and proceeds to develop a <br />noise impact based on either one unit or the other unit running alone. <br />brochure which can be found at: <br />http://ieeco.net/Documents/HVACs/MarvairComstat3Controller.pdf <br />Here it clearly states that the lead lag system is designed so that units alternate in service and that <br />both units are operated at the same time whenever the cooling load requires. This means that <br />both units do operate at the same time, contrary to SAA claims. <br />4 <br />
