For the interim <br />50 gpm treatment system, the discharge pipe will be laid at ground surface, except where it crosses <br />the existing access road where it will be properly buried with appropriate bedding or a culvert. At <br />the temporary outfall on Ralston Creek, the pipe will daylight and the flow will be routed onto a rip <br />rap apron to prevent excessive scour and erosion at the outfall. Flow will be visible, measurable, and <br />adequate for sampling at the outfall. <br />4
