• Dewatering - in order to optimize design/space for the solids handling building expansion, there is enough difference in the footprints for the different technologies (screw press, fan press) where it would help if the City could indicate a preferred technology and/or manufacturer.
• Equipment and lab/office buildings. Information from the City's analysis for required rooms/space needed for these facilities. Some associated issues that we discussed that you should consider in furnishing this info to us:
  • The lab component will be the most expensive $/sq ft, so recognition that a big lab will impact $.
  • Current proximity of the lab/office to the MBR support building. If the MBR support building gets classified as "H-4" building occcupancy type, which it likely could if all chemicals were stored inside, then we would be looking at 2-hour fire walls or a 20 to 30 foot required setback to the lab/office or other structure. That might make the space available to the property line on the east side (unacquired Future Admin area) too small to fit the building while maintaining the setback. Storage of the hypochlorite outside should probably be considered if it avoids that occupancy class. Again, the lab/office was shown as a separate bldg so that employees could have separation from noise, mostly from the blowers. From the noise standpoint, we could look at switching the lab/office to the south and equipment building to the north, but again probably not enough room for the 4 bays that are desired with the equipment bldg.
• Direction on backup power/emergency generation. City discussion with the PUD to determine if the City is going to buy and operate the unit, or if a shared purchase/ownership with the PUD will be sought. Also, our rough electrical load calcs at the moment show the potential need for a 1.5 megawatt unit. Would the City consider utilizing the plants existing 250 kW generator to help meet this load and/or would the City consider staggering the backup power supply, such that a 1 megawatt unit is furnished initially, and a 500 kW is added at a later date. The disadvantage to installing a full 1.5 megawatt generator is the large fuel tanks that would be required with it and the need to exercise the unit/turn over the fuel.
• Gas service. We don't believe any of the current plant receives gas supply from the local provider. Would there be a desire to run a gas supply to new facility for building heating purposes?

Thanks -
