Dear Ms. Gore:
Marine Corps Base Camp Lejeune (MCB CAMLEJ) is taking all
necessary steps to ensure complete compliance with House Bill 1160 of
the Clean Water Act of 1999. This act requires MCB CAMLEJ to provide
the public with an annual report that summarizes its collection
system' s performance over a 12-month period. The enclosure is the
July 2017 - June 2018 MCB CAMLEJ Advanced Wastewater Treatment Plant
System and Wastewater Collection System Performance Report. This
letter certifies that the report is accurate and complete.
Residents were notified of the availability of the report. The
notice was published in the Base newspaper, "The Globe", which also
covers the Marine Corps Air Station New River. The report document is
available on the MCB CAMLEJ website:
http://www.lejeune.marines.mil/OfficesStaff/EnvironmentalMgmt/
AnnualReports .aspx.
If you require additional information or need clarification of the
information provided, please contact Mr. James Marshall-Zank,
Environmental Quality Branch, Environmental Management Division, G-F,
at (910) 451-9122 .
Sincerely,
g. i( /G2�YY�`
