Hey Brion! Yes, it’s been busy and 6 months? Really? Time files! Below are my answers to yourquestions. 1)    We do not plan to inject anything in these wells. I just listed any permit numbersthat exist for the site as the permit requests. The purpose of the two monitoringwell are horizontal definition of the plume.2)    Anticipated construction (may vary depending on lithology encountered duringdrilling, but gravel pack typically 3 feet above screen, and 2 to 3 feet of bentoniteseal, then grout to land surface:11-MW17: 7 feet casing, 13 feet screen, gravel pack 10-20’ BLS, bentonite 8-10’BLS, grout 0-8’ BLS11-MW17D: 40 feet casing, 10 feet screen, gravel pack 37’ – 50’ BLS, bentonite5’-37’ BLS, grout 0’-5’ BLS3)    I do not know of any other sources of possible contamination within 500’ of the site.All properties are on town sewer, and I do not know or any agricultural or industrialcontamination sites within 500 feet.

Subject: NCDOT Site No. 11 - Monitoring Well Permit Application - Additional information Needed

Hi Katie,

I hope things have been going well for you, hard to believe it has been six months since I left GMA.

I have briefly looked over the monitoring well application that you submitted, I additional
information for a couple of things:

-          We will need the original copy with the “wet” signature of the applicant, without the ”wet”
signature we cannot issue the permit.
-          I need additional information on the proposed well construction, including interval for the
gravel pack, bentonite seal and grout.
-          Also under the “Additional Information” Section e. of the permit, let me know if any of these
sources are present within 500 feet.

Please feel free to call me if you have any questions.

Thank you,
Brion
