If yes, please explain:
2. List any items that you would like the NPDES Unit or Non -Discharge Unit Central Office to obtain through an
additional information request:
Item
Reason
Revise site plans
Site plans depict a 3BR house and application is for a 4BR house. Will
footprint of house change with addition of a bedroom? Revise site plans to
depict 4BR and verify that setbacks and location of house and systems remain
the same.
3. List specific permit conditions recommended to be removed from the permit when issued:
Condition Reason
4. List specific special conditions or compliance schedules recommended to be included in the permit when issued:
Condition
Reason
Specifications of fill
Potential that some fill will needed to be brought it during system installation.
material
Acceptable fill needs to be used.
Certification from Soil
Scientist regarding suitable
Certification from soil scientist stating that suitable fill as outlined in permit has
fill and depth to SHWT
been used and that required vertical separation to SHWT has been met.

V. ADDITIONAL REGIONAL STAFF REVIEW ITEMS
A site visit was conducted on 4/7/20. Borings were conducted in the area of the proposed irrigation areas. Borings were consistent
with those depicted in the soils report. Depth to SHWT was greater than 12 inches. There were some small areas that had ruts that
may require some additional fill. If fill is used in these areas, then it needs to have specific conditions as outlined in permit and the
soil scientist needs to certify that fill and depth to SHWT. The proposed loading rate of 20.58 inches/year appears to be appropriate
based off the Ksat data as well as site conditions.
Site plans depict a 3 BR house. Application is for a 4BR house. Will the footprint of the 4BR house impact the setbacks of the
system to house and other components? Revised site plans need to be submitted that depict accurate footprint of house.
RRO recommends that conditions be put in the permit requiring specific fill criteria and a soil scientist certification regarding the fill
and the depth to SHWT.
