MEMORANDUM FOR RECORD
SUBJECT: Pee Dee Mitigation Site - NCIRT Comments during 30 -day Mitigation Plan Review
June 13, 2019
PURPOSE: The comments listed below were provided during the 30 -day comment period in accordance with
Section 332.8(g) of the 2008 Mitigation Rule.
NCDMS Project Name: Pee Dee Mitigation Site, Montgomery County, NC
USACE AID#: SAW -2012-01077
NCDMS #: 95350
30 -Day Comment Deadline: May 30, 2019
Todd Bowers, EPA:
In general, I agree with all responses and approaches to adaptive management that RES proposes to correct site
deficiencies and resume credit release at the Pee Dee site. My only comment is that RES should clearly state the
stream mitigation units that the proposed action will release or those that are no longer being sought such as the
Thompson 1 old pond bottom that is not being reworked for credit (due to budgetary constraints).
As an IRT member, I encourage RES to continue to monitor the site and provide the IRT with adaptive
management needs as they arise in order to minimize any time between problem identification and correction.
Mac Haupt/Erin Davis, NCDWR:
I am ok with the proposed Modification Plan. However, I would like some clarification as to how they are
measuring stream flow given the placement of the flow gauges. I am assuming they are adjusting the elevation
to the riffle above or below, since they are all located in pools.
Kim Browning, USA CE:
I question the flow, and functional uplift, of including the reach above the cracked pond bottom. I generally agree
with the adaptive management plan, especially the need for flow gauges on the reach above the pond and the
privet treatment.
