Idaho Admin. Code r. 58.01.16.600 - LAND APPLICATION OF WASTEWATER(S) OR RECHARGE WATERS
Land application of wastewater or recharge waters is subject to the following requirements: (3-31-22)
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. (3-31-22)
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.
(3-31-22)
03.
Hazard or
Nuisance Prohibited. Wastewaters must not create a public health hazard
or a nuisance condition. (3-31-22)
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: (3-31-22)
a.
The nature and volume of wastewater material or recharge water;
(3-31-22)
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 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: (3-31-22)
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. (3-31-22)
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. (3-31-22)
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. (3-31-22)
