is critical. It's important to look in person, not just on paper, it's a challenging spot for trucks <br /> with other traffic. Tom Fudala asked if we need a second entrance for the fire department, <br /> Anastasia Rudenko answered no. Joe Lyons said a potential other entrance could be off Meeting <br /> House road. <br /> There was discucssion about putting up a fence around the proprerty. Joe Lyons asked if we were <br /> legally required to put up a fence, Kent Nichols said right now it's a federal requirement. Joe <br /> Lyons said he is firmly against planting,would rather build a 6-8 foot berm. It would insulate <br /> sound,hide view from neighbors, it would naturally fill in and there is no maintenance. Tom <br /> Fudala disagreed and would rather have plantings. <br /> Kent Nichols said one thing to really put some critical thought into is the collection process/odor <br /> control. May want to consider one common dumpster system. It's very operator intensive to <br /> have them combine everything into one dumpster, and if that dumpster isn't in the building <br /> where the odor control is, you've created a second source for odor control. Lenna Quackenbush <br /> and said right now what they're looking at for collection system is a hygenic bagging system, <br /> essentially like a trash bag. That often helps with odors. Tom Fudula asked how many bags per <br /> day, Val Peter said it really depends on the volume that's coming in. He recommended a public <br /> outreach for proper disposal, like a"sewer savvy" flyer. <br /> Lenna Quackenbuch said as far as the number of screens, after discussing,they would want full <br /> redundancy. There would be a cost comparison of more screens vs. life of membranes. Tom <br /> Fudala asked if there were any issues if one screen were out for a while, Lenna Quackenbush <br /> replied that each screen can handle the whole thing. <br /> Kent Nichols said one of the things he'd like to point out from an odor control point is that <br /> sometimes you'd need to pull out the membranes to do maintenance on them, it's best to be <br /> enclosed so they can do that in all weather and maintain odor control. One thing he would <br /> challenge is covering certain areas with something that would be a little more efficient so that we <br /> don't enclose areas where there is no function. <br /> In regards to screens, Kent Nichols said it's crucial to put careful thought in. He suggests <br /> oversizing racks long term or lean towards 3"instead of 2 membranes. If there was a long term <br /> problem with one membrane, you'd still have 2 operational membranes. Joe Lyons asked about <br /> keeping an extra one as a reserve, Kent Nichols advised against that because they will degrade if <br /> out of service. Keep all in service, and take out in rotation to clean and service. Use all 3 <br /> normally, but have 50%more that you need, it extends life. Lenna Quackenbush said they <br /> designed so that l membrane can handle peak size for one day. It's a good point and they will <br /> continue to look at it. <br /> Kent Nichols said it's a really important point when you're trying to keep things cost effective <br /> and make sure things actually operate efficiently, when you get into your later phases and you <br /> have excess units you're trying to keep in service when you have larger flows, it actually works <br /> against you. Ultimately, start with a couple blowers,then two bigger blowers in the second phase <br /> instead of more blowers of the same size. Anastasia Rudenko said that this is a very conservative <br /> design,they will continue to refine this. Tom Fudala said it's important to remember that this is <br />
