Subject:Onslow Quarry 401 WQC
EXTERNAL MAIL

Gentlemen,

After speaking with Thomas and Phillip last week, I understand that Martin Marietta plans to pursue an
Individual Permit to impact the intermittent stream channel that we discussed last month. The Division believes
that the Nationwide Permit/401 Water Quality Certification issued to impact the ditch upstream of the channel
allowing mining of the stream’s entire watershed would have a direct impact on the hydrology of the
intermittent stream even though the stream itself is avoided. Therefore, the Division believes that it would be
appropriate to rescind General Certification 4092 issued on May 25, 2017 if Martin Marietta does not apply for
an Individual Permit/401 WQC to impact the stream channel within 60 days of this email.

Thanks,
Jennifer
