ADDITIONAL REGIONAL STAFF REVIEW ITEMS NCDEQ does not currently have specific guidelines addressing site characteristics for fill systems. If the WQ permit is issued before the fill project takes place the WQ permit is being issued for an area that is currently unsuitable for wastewater disposal. This office recommends that this permit be issued for construction only and that an additional soils report certifying the fill system be required once site improvements have been completed. The additional soils report should address the following: Soil compaction being adequate and stable for the proposed irrigation Saturated hydraulic conductivity of the least permeable layer Soil fertility report for fill material and amendments (if any) that were added to fill material Verification of fill suitability and depth of fill (and to the SHWT) across the field This office recommends that only after review of the additional soils report by Division staff should the permit be reissued for operation. The proposed disposal field is in a wooded area. The following modifications to the provided Fill Application Plan are also recommended: Clear and grub site by hand in such a manner as to minimize native soil loss and compaction. ace and least five (5) feet beyond the proposed wetted area on all sides. The fill material should extend at least five (5) feet beyond the wetted area and blend into the natural contours of the area. Remove vegetation less than 8 inches in diameter from the disposal area. Avoid placing fill material under the drip line of any trees that are to be left within the disposal area to prevent tree death (an arborist can provide more guidance on tree protection). The application area Fill Plan will need to be modified to compensate for any area removed from the proposed application area for tree protection. FORM: WQROSSR 04-14 Page 5 of 5
