Through: Ed Beck, Regional Supervisor, DWQ, SWPS, Wilmington Regional Office (WiRO)
Date: November 12, 2008
SUBJECT: Shelter Creek Quarry Mine Expansion
This Office has reviewed the mine expansion application for an Individual Permit (IP) for additional wetland
impacts. We have the following concerns:
1) The IP application dated 10/13/08 requests 46.92 acres of wetland impacts, the map labeled as
Attachment 6 shows the total wetland impact area as approximately 33.46 acres. The map identified as
enclosure # 42 has a chart that shows 47.45 acres of approximate wetland impact. Please state the correct
amount of wetlands proposed for impact and correct all the maps and Written descriptions so they are
consistent. Please identify which wetlands have been identified as isolated and include them in the
calculated wetland impacts and narrative for the State.
2) Please show on an overall map, the wetlands to be impacted and in what phases and also identify the
required 50 foot undisturbed buffer by the Land Quality Section from the property line and/or wetlands.
3) The maps indicate there will be a proposed "future" ditch on the northwestern side of the property (Phase
IA). There are wetlands shown to abut this property line. Please indicate how this proposed ditch will
not impact/drain additional wetlands offsite.
4) There are onsite and offsite wetland monitoring wells. Please show the previously collected data and
provide a summary of these findings.
5) The proposed compensatory mitigation does not meet the requirements described in 15A NCAC
2H.0506(h) (1)-(7). Please give a detailed compensatory mitigation plan that will meet the State's
requirements. If there is onsite restoration/creation proposed, please detail what will be required to
accomplish this, the planting plan and the monitoring plan that will also be required.
6) In the narrative accompanying the IP application on page 14/27 states "that Phases IA and IIB, as
permitted would be mined out in 12 to 14 years". Please clarify if this should be Phase IA and IIA.
7) A really good overall site plan identifying the wetlands (isolated vs jurisdictional), which wetlands will be
impacted in each phase, monitoring well locations, buffer limits etc. would be beneficial to this reviewer.
