Section 58.01.16.600 - LAND APPLICATION OF WASTEWATER(S) OR RECHARGE WATERSLand application of wastewater or recharge waters is subject to the following requirements:
01.Land Application/Reuse Permit. Idaho Department of Environmental Quality Rules, IDAPA 58.01.17, "Recycled Water Rules," require a permit prior to land application/reuse of certain types of wastewater.02.Applied Waters Restricted to Premises. Wastewater(s) or recharge waters applied to the land surface must be restricted to the premises of the application site. Wastewater discharges to surface water that require a permit under the Clean Water Act must be authorized by the U.S. Environmental Protection Agency.03.Hazard or Nuisance Prohibited. Wastewaters must not create a public health hazard or a nuisance condition.04.Monitoring. Provision must be made for monitoring the quality of the ground water in proximity of the application site. The ground water monitoring program is subject to approval by the Department. All data and reports resulting from the ground water monitoring program must be submitted to the Department upon request. The minimum frequency of monitoring and data submittal will be determined by the Department and in general will be dependent upon:a. The nature and volume of wastewater material or recharge water;b. The frequency and duration of application; andc. The characteristics of the soil mantle on and lithology underlying the application site.05.Basis for Evaluation. The evaluation for an approval to irrigate, either by sprinkling or flooding or surface spreading of wastewater material or by burying wastewater material or recharge water in the upper soil horizon as a method of treatment, must include, but will not necessarily be limited to, consideration of the following items:a. The type and quantity of wastewater(s) proposed for land application. In general, the wastewater(s) organic constituents are to be biologically degradable and inorganic constituents must be utilized by vegetation or those organisms normally present in the soil. Other wastewater(s) or recharge waters will be considered provided it can be shown that land application will not adversely affect beneficial uses of waters of the state.b. The nature of the soils and geologic formations underlying the application site. The entity proposing the activity must provide reasonable assurance that the soils and site geology will provide the required level of treatment and will not allow movement of pollutants into the underlying ground water.c. The ability of the soil and vegetative cover on the application site to remove the pollutants contained in the applied waters through the combined processes of consumptive use and biological and chemical inactivation.Idaho Admin.
