Explanation: The feature(s) listed above has or have been located on the Soil Survey of Johnston County, North
Carolina or the most recent copy of the USGS Topographic map at a 1:24,000 scale. Each feature that is checked
"Not Subject" has been determined not to be a stream or is not present on the property and is not subject to the
buffer rules. Features that are checked "Subject" have been located on the property and possess characteristics that
qualify it to be a stream and are subject to the buffer rules. There may be other streams located on your property
that do not show up on the maps referenced above but, still may be considered jurisdictional according to the US
Army Corps of Engineers and/or to the Division of Water Quality.
This on-site determination shall expire five (5) years from the date of this letter. Landowners or affected
parties that dispute a determination made by the DWQ or :Delegated Local Authority that a surface water
exists and that it is subject to the buffer rule may request a determination by the Director. A request for a
determination by the Director shall be referred to the Director in writing c/o Cyndi.Karoly , DWQ
Wetlands/401 Unit, 2321. Crabtree Blvd., Raleigh, KC 27604-2260. :Individuals that dispute a determination
by the DWQ or Delegated Local Authority that "exempts" a surface water from the buffer rule may ask for
an ad judicatory (tearing. You must act within 60 days of the date that you receive this letter. Applicants are
