<br />., <br /> <br />2.4 The 340 kv emergency generator would be located directly behind and connected to the <br />existing NSP transformer and new transfer unit. The emergency generator is approximately <br />16 feet long by 10 feet wide and ~tands approximately 11 feet tall. As a self-contained <br />emergency generator it is designed with a 600 gallon fuel storage unit and a 900 gallon safety <br />sub-tank for capturing fuel in the unlikely event of a leak or rupture. This emergency <br />generator, with its 600 gallon diesel fuel capacity, could run up to 54 hours. The walls of the <br />generator unit are designed with sound absorption material that are 10-5/8 inches thick and <br />were re-engineered to reduce noise reverberation by 50%. The generator will create 73 <br />decibels of sound when operating at full capacity. Because it is emergency equipment noise <br />regulations do not apply. The generator unit will be setback a minimum of six feet from all <br />existing exterior walls to meet the fire code spacing requirement. No detached outdoor fuel <br />storage tank will be installed. <br /> <br />2.5 The self-contained emergency generator shell will be painted white to match the building and <br />will appear to be an attachment to the building. <br /> <br />2.6 In conjunction with this request, the following has been provided for reVIew and <br />consideration: <br /> <br />. project narrative <br />. existing conditions/site plan <br />. emergency generator diagrams <br />. transfer unit and generator elevations <br />. photos of proposed location <br /> <br />3.0 Staff Comment And Findings <br /> <br />3.1 Because of the :&agile nature of the residents and their dependence on uninterrupted electrical <br />service, an emergency generator can be defined as on essential emergency service. <br /> <br />3.2 The proposed emergency generator is self-contained, including the fuel storage cell. <br /> <br />3.3 The City Code does not specifically address self-contained emergency electrical generators. <br /> <br />3.4 Due to the low flammability of diesel fuel the Fire Marshal prefers a diesel fuel operated <br />emergency generator as opposed to one operated by natural gas or liquid petroleum. <br /> <br />4.0 Staff Recommendation <br /> <br />4.1 The staff recommends approval of the request by Rosewood Estates for a permit to allow <br />installation of an emergency generator with a self-contained fuel storage cell within the front <br />yard of property located at 2750 Victoria Street North. <br /> <br />PF3106 - RCA (03/22/99) - Page 2 of 3 <br />
