New Hanover County
Dear Mr. Pearce:
On behalf of Exxon Chemical Americas, Law Engineering and Environmental Services,
Inc. (LAW) is providing this letter requesting approval of the modification of the
groundwater remediation facility at Exxon Terminal #4380. The remediation system
currently operates according to Non -Discharge Permit No. WQ0008129, renewed
October 14, 1998.
We plan to install two additional recovery wells to connect to the existing pump and treat
system. (Please see Figure 2 for proposed recovery well locations.) The purpose of these
wells is to capture and mitigate the migration of the para-xylene plume present at the site.
Each of the two recovery wells will be provided with a submersible pneumatic pump at 3
gpm to 5 gpm rates, like the existing 24 recovery wells. The treatment system is
permitted to operate at 144,000 GPD (100 gpm). Because the system operates at an
average flow rate of 40 gpm, the additional wells and subsequent additional flow will still
be well below the permitted flow in the existing permit.
Based on conversations between Mr. Ed Beck of Wilmington Regional Office, Division
of Water Quality, yourself, and Ms. Ashley Shaver of LAW, it is our understanding that
the aforementioned modifications may be implemented without a formal permit
modification application submittal. It is also our understanding, therefore, that your
approval of this letter of will also serve as your approval of the system modification.
