		(2) the design or design criteria for the following parameters meet the requirements of 18 AAC 72.220:  
			(A) design flows, conduit velocities, and pipe materials;  
			(B) hydraulic grade line considerations associated with pressurized portions of a sewer line;  
			(C) vacuum sewer lift segments;  
			(D) pump station, collection station, or holding tank capacities;  
			(E) overflows, alarms, solids handling, provisions for servicing, and emergency operations;  
			(F) manhole or cleanout placement, and methods for cleaning the collection system;  
			(G) siting with respect to health hazards, nuisance potential, stream crossings, and flooding;

		(7) the size of pipe for sewer lines complies with 18 AAC 72.040(b)(4) unless a waiver is granted under 18 AAC 72.040(c); and  
		(8) the collection and pumping system is proposed to discharge to an existing collection or disposal system, and adequate documentation shows that the
