				determines that those alternative points are more representative of disinfected
				water quality within the distribution system; to seek department approval under
				this paragraph for a system that uses groundwater combined with either surface
				water or GWUDISW, the owner must submit a request for alternate sampling
				locations; the request must include the disinfectant residual sample siting
				plan approved by the department showing each proposed alternative sampling
				location, a narrative rationale for relocation of the sampling site, a
				description or ratio of flow of groundwater and surface water at the proposed
