Kittitas County Transfer Station <br /> April 2018 Community Meeting Summary <br /> <br />Updated 5/31/2018 <br />4 <br /> <br />above groundwater. We will take the elevation and construction requirements into consideration <br />during the detailed engineering phase. The cement plant site is not located in the 100-year <br />floodplain. <br /> <br />• How do you plan to mitigate climate change? The current designs are based on a 100-year <br />floodplain, which may not be a severe enough standard, given climate change effects. <br />Response: While the 100-year floodplain is the standard for planning, we’ll develop the design once <br />we have detailed analysis of the selected site. The project team will engineer the selected site with <br />consideration for climate change impacts. <br /> <br />• What does the city have in mind for the current transfer station once the new one is complete? <br />Response: Currently, the City of Ellensburg does not have a specific plan for the current site. We will <br />repurpose the area as appropriate. <br /> <br />• Can you tell us more about the liners that will be used in the water collection basins (stormwater <br />ponds)? <br />Response: The stormwater ponds will be lined with a 40 to 60 mil layer of high density polyethylene <br />(HDPE) material. <br /> <br />• Regarding the current site, does Anderson Hay use your compost? <br />Response: Not that we are currently aware of. <br /> <br />• Is there the possibility of contamination seeping downhill onto the neighboring property, say in 10 <br />years from now? <br />Response: Transfer stations are not typically sources of groundwater contamination. For the <br />proposed compost area, monitoring wells will be installed around the site and will be monitored for <br />groundwater contamination. There are statutes and regulations that require environmental <br />monitoring. <br /> <br />• Is there ongoing monitoring for other parts of the site besides the compost facility? <br />Response: Yes. Stormwater will be managed and monitored in accordance with a site specific <br />Stormwater Pollution Prevention program. <br /> <br />• Since you’ve discussed your ability to engineer the strips of floodplain on the Old Highway 10 site, <br />does that mean you can do whatever you like on your property, regardless of floodplain <br />regulations? Will there be downstream or adjacent property impacts as a result of your engineering <br />of the floodplain? <br />Response: Kittitas County has specific requirements when constructing facilities within or adjacent <br />to 100-year floodplains. In addition, the Federal Emergency Management Agency (FEMA) has
