Certification Statement: i I Matthew Tribett,CFPUA Eng.Mgr certify to the best of my knowledge that the addition of the volume of wastewater to be permitted in this project has been evaluated along the route to the receiving wastewater treatment facility and that the flow from this project is not anticipated to cause any capacity related sanitary sewer overflows or overburden any downstream pump station en route to the receiving treatment plant under normal circumstances, given the implementation of the planned improvements identified in the planning assessment where applicable. This analysis has been performed in accordance with local established policies and procedures using the best available data. This certification applies to those items listed above in Sections I and II plus all attached planning assessment addendums for which I am the responsible party.

The following applies: I i i I i i i Therefore: Given reasonably expected conditions and planning information,there is sufficient justification to allow this flow to be permitted,without a significant likelihood of over-allocating capacity in the system infrastructure.
