The paperwork submitted to the Planning Department for this project was reviewed by Craig Valentine for the University Area CC. We are submitting them from the Community Council. They are talking about an 8MW plant of 2 MW generators. This gives them a plant with 6MW of ‘prime power” (power available with one single largest generator down). They probably sized the plant by using the Corps of Engineers technique of counting up the breaker ratings; they didn’t say but they did but they do say the 6MW of prime power is sufficient to carry the UMed load. Therefore the load could be grossly overestimated. If the plant is pulling slightly over 4MW of load then they will have one 2MW generator struggling to stay on line because it doesn’t have enough load (generators should be loaded to at least 80%). Therefore 2 1MW generators in lieu of the 4th 2MW generator might be a better mix. They are calling for the fuel line to be 3’ below grade. Military standard is 7’ to guard against military aggressor action (bombs, etc). The guys might want to check advised depth with Homeland Security Lastly tankage. The mandated 4 day supply until refill is required is a bit over the top (the Air Force—unofficially I admit—considered a 3 day supply as a good rule of thumb). The plan calls for a 7 day supply and rounds up from there. They only need approx 57,000 gallons of fuel (for 4 days) not 140,000 gallons. I assume there is a sump somewhere and pump to take care of the inevitable water ponding in the containment. That is not something that engineers forget about but it ought to be located near the equipment pad so that a guy doesn’t have to wade through knee deep water to activate the pump. And then It needs to go through a filter system. Alternatively you might consider putting a cover across the entire containment area Intended landscaping might make the Fire Department unhappy. I see the plan has a gated access to the tanks—excellent. We need to have ability to bring in heavy machinery when tank maintenance is called for (every few years). Be sure say 12’ is kept clear around the tanks.
