modifcation request received on April 10, 2002, we are forwarding herewith Permit No. WQ0002161, dated July
31, 2002, to Carolina Friends School for the continued operation of the subject wastewater treatment and spray
irrigation facilities, rehabilitation and storage expansion of the existing lagoon and a one time land application of
lagoon solids to the permitted spray field.
This permit shall be effective from the date of issuance until June 30, 2007, shall void Permit No.
WQ0002161 issued November 3, 1999, and shall be subject to the conditions and Iimitations as specified therein.
Please thoroughly read this permit as several conditions have been modifed, removed or added since your

adequate system for collecting and maintaining the required operational information will result in future
compliance problems. Permit conditions 1(2), II(4-5) and 11(8-10) are specifically important to the one time land
application of lagoon solids. Note also that the Groundwater Division has requested permanent abandonment of
the two existing monitoring wells, an updated map and lagoon liner certification as outlined in Section IV of this
permit. Permit condition I1(14) requires that animals not be allowed within the lagoon and sprayfield area at any
time. Permit conditions II(16-18), II1(2) and 111(4) are new conditions related to the wastewater treatment and
disposal system applicable to all Permittee's owning such a system
if any parts, requirements, or limitations contained in this permit are unacceptable, you have the right to
request an adjudicatory hearing upon written request within thirty (30) days following receipt of this permit. This
