(7) A discussion of the relationship between the affected aquifers of the site to
local and regional geologic and hydrogeologic features;and
(8) A discussion of the groundwater flow regime of the site focusing on the
relationship of the plume and remediation system to groundwater receptors,
groundwater discharge features, and groundwater flow media.
D. Demonstration of Hydraulic Control. As specified in 15A NCAC 02T.1604(d), computer
modeling or predictive calculations based on site-specific conditions shall be provided to the
Division by the applicant to demonstrate that operation of the system will not cause or

showing all facility-related structures and fences within the treatment,storage
and disposal areas;
(2) Locations of all test auger borings or inspection pits;
(3) The location of all wells (including usage and construction details if available),
designated wellhead protection areas,streams(ephemeral, intermittent,and
perennial), springs, lakes,ponds,other surface drainage features,and any other

Subject: Site 1083 Annual Report Extension Request for NCDEQ UIC Branch
Mr. Rogers,
MCAS Cherry Point requests an extension for the Site 1083 Annual Report in association with the surfactant recirculation
activities.
In accordance with the Groundwater Remediation Permit Number WQ0035748 aboard Marine Corps Air Station, Cherry
Point NC, effective on April 1,2014, an annual report is generally submitted in the April/May time frame. Mobile
surfactant recirculation activities were completed during 2015 and the post-recirculation monitoring activities are
underway(first quarterly sampling event conducted in February 2016). It has been decided that no additional injection
or recirculation activities will be performed at this site in 2016;therefore, we are planning to conduct another quarterly
sampling event in May 2016 . The current deadline of the annual report(approximately May) coincides with the
proposed final sampling activities to complete the previous round of surfactant recirculation monitoring activities. In
order to provide a comprehensive annual report with analytical results from both quarterly sampling events (February
and May 2016), it is requested that the deadline for the annual report be extended Until late June/early July 2016 .
Please let us know if this extension is a possibility. We are happy to address any questions or concerns you may have
regarding this extension.
Respectfully,

Dear Mr.Rogers: Water Quality regional
Operations Section
Enclosed for your review is the Annual Report(March 2015-May 2016)for the Surfactant
Recirculation Project,Building 1083,Marine Corps Air Station(MCAS)Cherry Point,North Carolina.
The goal of the surfactant recirculation events is to remove residual free-phase product and reduce
groundwater contamination in order to reduce the site risk classification to Low.
Surfactant recirculation events took place between May 5, 2015 and November 6,2015 in Areas A
and B. The events consisted of extracting groundwater that was treated and mixed with a surfactant
solution and re-injected into targeted wells. Manual surging followed the re-injections before the final
extraction and disposal of contaminated water. Additionally, a nutrient and bacteria solution was injected
into targeted wells before field activities were completed. Monthly gauging of select monitoring wells for
depth to water and free-phase product thickness continued as part of the MCAS Closure and Management
Program(CAMP). Groundwater`-sampling-of se Tecteonitoring wells followed the completion of the
recirculation activities for two consecutivequarterse(Februaiy`201:6=anc-11VIayd2a 16). Results indicate free-
phase product thicknesses at the site have been diminished since surfactant recirculation activities began,
however current elevated groundwater table elevations at the site may be preventing mobile free-phase
product from being detected. Nia additionaLsur-factant-zecirculation acti ifs es$'are sche-duledTbutahe site will
continue to be gauged monthly and monitored semiannually as part of the CAMP program.
If you have questions or require additional information,please contact Ms.Elizabeth Harrison at(252)

Dear Mr. Slusser:
Enclosed for your review is the first Interim Report (December 2013-
February 2015) for the Surfactant Recirculation Project, Building 1083, Marine
Corps Air Station (MCAS) Cherry Point, North Carolina.
During t.- aforementioned time period, no surfactant related activities
were conducte. . -•wever, we are submitting this report per the requirements of
the Groundwat-r Remediation Permit for Building 1083 Area Remediation Sites,
Permit Number . Q0035748 Monitoring and sampling was conducted under another
project during - is p-. iod which indicated an increase in thickness and extent
of free-phase pro.. in Areas A and B. It is suspected that the previously
conducted surfactant recirculation activities liberated free-phase product
trapped in the subsurface, causing it to mobilize and accumulate in the
recovery wells. Due to the recurrence of the free-phase product, Cherry Point
is currently conducting an additional surfactant injection at Areas A and B.
If you have questions or require additional information, please contact
Ms. Elizabeth Harrison at (252) 466-4562 or by email at
[e-mail].
Sincerely,
