Please take time to review this permit thoroughly. Of special interest are the following items:
General Items:
* Note within permit text, that the "Division" refers to Division of Water Quality.
Note that both Permittee Project Name, and mailing address, have been changed to reflect the
submitted current information, received by the Division, on May 1, 2001,

systems initiated after December 31, 1983, is established at either (1) 250 feet from the waste
disposal area, or (2) 50 feet within the property boundary, whichever is closest to the waste
disposal area. An exceedance of Groundwater Quality Standards at or beyond the Compliance
Boundary is subject to immediate remediation action in addition to the penalty provisions
applicable under North Carolina General Statute 143-215.6A(a)(1).

discharge into the infiltration gallery. The treated water that is discharged into the infiltration
gallery must not violate the Class GA Groundwater Quality Standards for any constituent beyond

prior to discharge into the infiltration gallery. If the treatment system fails to consistently achieve
this standard, additional treatment units, or changes in operational methods, may be required.
13. Isoconcentration (lines connecting points of equal concentration) maps in both the vertical and
horizontal directions shall be developed using the SeRtember sroundwater monitoring data, for
benzene. A water level contour map must also be developed on a yearly basis. Two copies of

4718), of the occurrence and as a written submission within five days of the occurrence (3800
Barrett Drive, Suite 101, Raleigh, NC 27609; fax [phone]). The written submission shall
contain the following information: A description of the noncompliance and its cause, the period
of noncompliance, including exact dates and times; and if the noncompliance has not been
