Land Application Of Wastewaters Or Recharge Waters

Land application of wastewater or recharge waters is subject to the following: (7-1-26) 01. Reuse Permit. IDAPA 58.01.17, “Recycled Water Rules,” govern when a permit prior to land application or reuse of certain types of wastewater is necessary. (7-1-26) 02. Applied Waters Restricted to Premises. Wastewaters or recharge waters applied to the land surface must be restricted to the premises of the application site. (7-1-26) 03. Hazard or Nuisance Prohibited. Wastewaters or recharge waters must not create a public health hazard or a nuisance condition. (7-1-26) 04. Monitoring. Provision must be made for monitoring the quality of the groundwater in proximity of the application site. The groundwater monitoring program is subject to approval by the Department. All data and reports resulting from the groundwater monitoring program must be submitted to the Department upon request. To determine the frequency of monitoring and data submittal, the Department will consider the following: (7-1-26) a. The nature and volume of wastewater or recharge water; (7-1-26) b. The frequency and duration of application; and (3-31-22) c. The characteristics of the soil mantle on and lithology underlying the application site. (3-31-22) 05. Basis for Evaluation. The evaluation for an approval to irrigate, either by sprinkling or flooding or surface spreading of wastewater or recharge water in the upper soil horizon as a method of treatment, must include, but will not be limited to, consideration of the following: (7-1-26) IDAHO ADMINISTRATIVE CODE IDAPA 58.01.16 Department of Environmental Quality Wastewater Rules Section 650 Page 54 a. The type and quantity of wastewaters or recharge water proposed for land application. In general, the organic constituents are to be biologically degradable and inorganic constituents must be utilized by vegetation or those organisms normally present in the soil. Other wastewaters or recharge waters will be considered provided it can be shown that land application will not adversely affect beneficial uses of waters. (7-1-26) 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 groundwater. (7-1-26) 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.
