Dear Mr. Kotis:
In accordance with your request for renewal and modification received July 31, 2002, and subsequent
additional information received October 23, 2002; June 26, 2003; October 10, 2003; and December 1, 2003, we
are forwarding herewith Permit No. WQ0013808, dated January 23, 2004, to Kotis Properties, Inc. for the
modification to, and continued operation of the subject wastewater treatment and surface irrigation facilities.
This permit shall be effective from the date of issuance until December 31, 2008, shall void Pen -nit No.
WQ0013808 issued April 3, 2001, and shall be subject to the conditions and limitations as specified therein.
Please pay particular attention to the monitoring requirements in this permit. Failure to establish an adequate
system for collecting and maintaining the required operational information will result in future compliance
problems.
Please note that this permit is being issued as a renewal of the 1,700 GPD existing wastewater
treatment system. In addition, approval for construction of modifications to the wastewater treatment,
storage, and disposal system are being approved to increase the approved flow to 3,600 GPD. The request
for approval to increase the flow to 2,700 GPD without modification to the system is not being approved.
Storage needs for a 2,700 GPD system are not met by the existing system. However, when the approved
modifications to the storage system are completed the flow may be increased to 2,700 GPD prior to
modifications to the rest of the wastewater treatment and irrigation system being completed.
Please note Condition H. 1 and Condition H. 3 carefully. During inspections by Division staff in
July 2003 and in November 2003 it was noted that the drip fields have not been properly maintained.
Vegetative growth had been removed by chemical addition, leaving bare soil in many areas. In addition,
drip lines were in disrepair with breaks and holes in the distribution lines. Failure to properly maintain
the irrigation areas as well as the drip irrigation equipment shall be considered a violation of this permit
and subject to violations and enforcement actions by the Division.
