Current through Register Vol. 42, No. 11, August 30, 2024
All applications to land apply any permitted septage shall
include the following information:
(1)
A plat map showing the exact location of the proposed facility, indicating the
total acreage and the setback distances from key natural and man-made features
referenced in Rule
420-3-6-.14 Sites for Land
Application Facilities that are within 1,000 feet of the
facility.
(2) A High Intensity Soil
Map, prepared by a professional soil classifier, that shall meet the following:
(a) The map scale shall be 1-inch equals 100
feet or larger.
(b) A minimum of
four borings per acre is required to define the soils. When a grid system is
not used, boring location shall be dictated by the landscape or in a manner to
best define the soils that occur. All borings shall be flagged and
numbered.
(c) Soil surveys or maps
shall conform to the National Cooperative Soil Survey (NCSS)
Standards.
(d) Soils shall be
classified according to U.S. Soil Taxonomy to the series level and map units
shall generally consist of consociations. Complexes may only be used under very
limited conditions when two or more dissimilar soils or soils and rock outcrops
cannot be separated.
(e) Soil
series boundaries shall be plotted on a map.
(f) A High-Intensity Soil Map requires a
carefully prepared base map on which the professional soil classifier shall
accurately locate soil boundaries. A minimum of a 2-foot contour interval
topographic base map is required-
(g) The following information is required for
all maps:
1. A title block or caption that
states the project or client name.
2. The date of the survey.
3. A north arrow for orientation.
4. The scale of the map.
5. The soil mapping intensity.
6. The signature, stamp or seal, address, and
telephone number of the professional soil classifier.
7. A special symbols legend, if needed,
defining special features identified on the survey map (i.e., springs, rocky
outcrops, wells, sinkholes, gullies, etc.).
(h) The information listed below shall
accompany or be provided on maps in table form with detailed maps for each
boring:
1. The name of the soil series (or
closest series with similar interpretations).
2. The percent slope or slope range
class.
3. The depth to
ASHES.
4. The depth to other
restrictive layer(s) or horizon(s).
5. The assigned or adjusted loading rate.
6 Additional notes and information
as appropriate.
7. Soil
group.
(i) Soil maps
shall be color-coded to differentiate between map units and/or soil
groups.
(4) A hydrogeological report,
performed by a hydrogeologist, relating to the area of the proposed facility,
verifying that the application of septage or septage mixed with other permitted
waste over the area of the proposed facility will not pose a threat to the
groundwater and aquifer, to surface waters, or to any public or private
drinking water wells.
