I have forwarded this email onto the Division Bridge Manager to inform him of the regulatory requirements and will let
you know when the precon for the project is scheduled.

Thank you

Trish,
Thank you so much for the documentation you provided concerning the site assessment at Johnstown Road. Based on
the results contained in that report, it appears the constituents found in the groundwater sample from the bore pit are
below the 2L standards, except 1-Methylnapthylene. The result was 3.6 micrograms with the 2L groundwater standards
at 1 microgram. There were no constituents found in the surface water samples from Mill Creek. The soil sample result,
submitted as sample ‘B1-A, SS-17, 3’-5.5’, which contained 3800 mg/kg of diesel petroleum, appears to be a surface spill
with no further migration into the groundwater or surface water. Based on the presented information, no stream
impacts or exceedances of surface water standards are expected from the pumping and discharging of groundwater
from the structure pits/shafts to Mill Creek.

I have forwarded the report you sent me yesterday to Ron Taraban, Supervisor for the Division of Waste Management-
UST Section, Mooresville Regional Office and Dan Graham, Hydrogeologist for Lincoln County. Based on the
conversations I had with Mr. Taraban and Mr. Graham, I expect some limited involvement from their Section. Mr.
Graham can be more clear with DWM’s specific expectations. It is my understanding he is going to issue a letter stating
the need for proper soil disposal, which DOT was already planning. He is copied on this email for ease of
communication. Mr. Taraban is the issuer for on-site soil remediation permits and is in this office.

With the current information, and although this is a NW3 permit and no written concurrence is required, I would like to
attend the precon as well as observe the groundwater discharge from any pits/shafts constructed on site. Please be
advised that all contaminated soil must be properly disposed of and not stockpiled on site, either in the right of way or
streamside. Please contact Mr. Taraban for an on-site disposal permit for the adjacent farm should that be the desired
method of disposal. If the soil is to be hauled off and properly disposed of at another site, it must be stored in a leak
proof container that ensures either no exposure to contact with stormwater or no discharge from contact with
stormwater. Although it was included in the submittal that the contractor is responsible for any contaminated soil
permits, please be advised that NC DOT is the permittee as pertains to the construction stormwater permit, ROW
owner, and NCS000250 permit and therefore will be viewed as the responsible party by DWR should there be an illicit
discharge of petroleum contaminated water to Mill Creek.

I am more than happy to spend any extra time required to aid DOT in site compliance regarding this site. Please forward
to all interested parties in Division 12.

Please let me know if you have any questions.

Thank You,
Donna Hood

Subject: RE: Johnstown Rd bridge project

Hi Trish,
Thanks for the follow-up. Concerning the Johnstown Road bridge replacement, there will be at least one other agency
involved—NC Division of Waste Management-Underground Storage Tank Section. They are in charge of underground
petroleum contamination. I have not had a chance to talk with them in depth yet, so I would ask that you give me that
chance before moving forward. I am on vacation today through next Tuesday, a staff meeting in Raleigh on next
Wednesday, and return to the office next Thursday.

The issues at this site could be several: source of the contaminated soil, removing contaminated soil, proper disposal of
the soil, and pumping (and subsequent treatment and disposal) of any contaminated groundwater from the bridge
installation.

At this point, in my profession experience, the hardest problem to address is the potentially contaminated groundwater
which cannot be discharged to the stream—unless a huge problem is unearthed as the source.

Let me know if you need any other clarification. I will get back to you next Thursday.

Have a great weekend,
Donna

Donna,

I spoke with Steve Rackley, the division bridge manager, this morning regarding the possibility of dealing with
contaminated groundwater during the construction of the new bridge. When you get a chance could you send me an
email reiterating the problem and what other agencies might be involved in dealing with contaminated water being
pumped out while constructing the bridge supports?

Thanks
Trish
