Dear Ms. Sanchez -King:
This letter provides the North Carolina Division of Water
Resources (NC DWR), Wilmington Regional Office, with information
in reply to the November 30, 2023, Notice of Violation (NOV)
received by Marine Corps Installations East -Marine Corps Base
Camp Lejeune (MCIEAST-MCB CAMLEJ). The NOV identifies
violations pertaining to Collection System Permit No. WQCS00015
(Permit). Please see the information below and enclosed with
this letter to assist the NC DWR in understanding Camp Lejeune's
commitment to sustaining compliance with the Permit and other
applicable regulatory requirements for controlling and abating
water pollution.
As we previously self -reported, the wastewater collection
system on MCB CAMLEJ suffered a "sanitary sewer overflow" (SSO)
on November 5, 2023. The SSO began after an electrical voltage
spike at the transformer supporting pump/lift station TT99
(TT99) tripped TT99's control panel circuit breaker. After TT99
lost power, the TT99 diesel bypass pump failed to operate after
its priming bulb stuck.
The SSO occurred over approximately three hours before Camp
Lejeune returned TT99 to service and took immediate action to
remediate the site. MCB CAMLEJ estimated that approximately 500
gallons of untreated wastewater reached Northeast Creek. After
conferring with NC DWR, we further remediated the site with lime
and collected upstream, downstream, and outfall water samples in
the creek. Our November 7, 2023, water samples showed no
significant fecal coliform results.
Please see the enclosed "Remedial Actions Information Sheet"
for additional information about Camp Lejeune's current and
proposed actions for eliminating SSOs, sustaining effective
operation and maintenance, and improving Permit Compliance.
