In forming its opinion as to the acceptability of these wastes, the City and Health District will give consideration to such facts as the quantities of subject wastes in relation to flows and velocities in the sewers, materials of construction of the sewers, nature of the sewage process, capacity of the sewage disposal system, degree of treatability of wastes in the sewage disposal system and other pertinent factors. The substances prohibited are those items listed as hazardous wastes by the Environmental Protection Agency (EPA) in the EPA priority pollutant list, or other substances deemed acceptable by the City, the North Central Health District or the Idaho Department of Health and Welfare, Division of Environment.
