County: Richmond
The purpose of this letter is to notify you that the NCDENR Division of Mitigation Services (DMS) is willing to accept payment for
compensatory mitigation for impacts associated with the above referenced project as indicated in the table below. Please note that this
decision does not assure that participation in the DMS in -lieu fee mitigation program will be approved by the permit issuing agencies
as mitigation for project impacts. It is the responsibility of the applicant to contact permitting agencies to determine if payment to the
DMS will be approved. You must also comply with all other state, federal or local government permits, regulations or authorizations
associated with the proposed activity including G.S. § 143-214.11.
This acceptance is valid for six months from the date of this letter and is not transferable. If we have not received a copy of the
issued 404 Permit/401 Certification/CAMA permit within this time frame, this acceptance will expire. It is the applicant's
responsibility to send copies of the permits to DMS. Once DMS receives a copy of the permit(s) an invoice will be issued based on
the required mitigation in that permit and payment must be made prior to conducting the authorized work. The amount of the in -lieu
fee to be paid by an applicant is calculated based upon the Fee Schedule and policies listed at www.nceep.net.
Based on the information supplied by you in your request to use the DMS, the impacts that may require compensatory mitigation are
summarized in the following table. The amount of mitigation required and assigned to DMS for this impact is determined by
permitting agencies and may exceed the impact amounts shown below.

Upon receipt of payment, DMS will take responsibility for providing the compensatory mitigation. The mitigation will be performed
in accordance with the In -Lieu Fee Program instrument dated July 28, 2010. In accordance with the directive from the February 8,
2011 IRT meeting, non -riparian wetland impacts located in the mountains and piedmont areas of North Carolina will be accepted as
requested, but mitigated utilizing riparian wetland mitigation credits.
Thank you for your interest in the DMS in -lieu fee mitigation program. If you have any questions or need additional information,
please contact Kelly Williams at (919) 707-8915.

RE: Request for Additional Information, Vulcan Lands, Inc. DWR# 02-0408 v2
Ms. Higgins
In response to your letter dated November 16, 2015 requesting additional information for the Vulcan
Materials Company Rockingham Quarry Expansion Project in Richmond County, NC, please find
attached the requested information regarding project avoidance and minimization and mitigation for
impacts. Three copies of the requested documents are attached.
As indicated in your letter,
1. Please provide more details regarding avoidance and minimization of stream impacts for this
project. (15A NCAC 2H .0506(f) and (g)].
• This Office believes that the overburden storage area can be reconfigured to minimize the impacts
to the stream by constructing road crossings for access to utilize all available upland areas of the property.
Please revise the plans to minimize the impacts or provide a detailed explanation of why this plan for the
activity cannot be practically accomplished, reduced or reconfigured to minimize impacts to the stream.
As requested, we reconfigured the overburden fill design to only utilize the available upland
areas of the property; this is shown on the exhibits titles, "5 Year Plan — Alternatives Analysis — Plan
View" and "5 Year Plan — Alternatives Analysis — Profile View".
In plan view there appears to be plenty of room for storage. In reality, the site is comprised of
ridges and stream valleys and is not flat. As such, if the fill only occurs on ridges with side slopes, much
less volume can be stored. The sides of the storage cannot be vertical, they must be gentle slopes to
prevent slope failure. Also, considerable area is occupied by erosion and sediment control structures at
the toe of all slopes as required by the State of North Carolina. As such, this area cannot be used to
accommodate fill volume.
Without impacting Stream HS:S4 or Stream RLS:P5 only two areas on the site are viable to
place any fill. The first area is on the south side of the existing storage area and north of Stream HS:S4.
The second area is located between Streams HS:S4 and RLS:P5. A third area exists on the east side of
Stream RLS:P5, but it is not viable because once the erosion and sediment control structures are
constructed there is no room available for material storage. The two areas shown have a storage
capacity of 4.7 million cy.
The 5 Year Plan overburden storage capacity needs are 2.4 million cubic yards (cy) for soil
overburden removed to expose the mineral and an additional 0.7 million cy for mine waste generated
each year. The total 5 Year Plan storage capacity requirement is 5.9 million cy; and the 20 Year Plan
capacity requirement is approximately 16.5 million cy. This is significant because without filling in
Stream HS:S4 the proposed plan will not even meet the needs of the 5 Year Plan. With filling Stream
HS:S4 the storage capacity needs are only met for approximately 8 or 9 years, assuming given sales
forecasts.
All of the surrounding land is either already developed into small parcels or occurs on the other
side of public roads or railroads that cannot be crossed or used for transport of material to be disposed
of. Therefore, the storage must occur on-site, within both the stream valley(s) as well as on ridges to
accommodate the needed volume.
Additionally,
2. Mitigation is required for losses of greater than 150 linear feet of stream and 1 acre of wetlands.
Please provide a mitigation plan that conforms to the requirements of 15A NCAC 02H.0500 for
2,557 linear feet of stream and .088 acre of wetlands or the amount of unavoidable impacts
remaining after addressing item #1 above. The mitigation plan may invovlve payment to a local
mitigation bank or in -lieu fee program, or on-site mitigation. (15 NCAC 02H .0506(h))
• You have indicated that you plan to restore 100 linear feet of stream on-site and make a payment to the
Division of Mitigation Services (DMS) to satisfy the amount of mitigation required, please provide
documentation from DMS indicating their willingness to accept your request to purchase stream and
wetland credits to mitigate for the proposed stream and wetland impacts listed in your application.
The acceptance letter from the NCEEP (DMS) is attached for the entire amount of mitigation
requested for the project. Vulcan Materials Company plans to pay a mitigation ratio of 2:1 for all stream
and wetlands impacts and a ratio of 1:1 for all man-made open water impacts as advised by the US
Army Corps. Vulcan Materials Company does not plan to take mitigation credit the 100 linear feet of
proposed stream restoration. This activity is only being performed as a part of the project construction to
open the waterway of Long Branch to the free passage and movement of aquatic life as a means of
benefiting the aquatic resource. The stream is presently obstructed by a collapsed and abandoned
highway culvert. Once opened, the banks will be stabilized but the stream segment will not be restored
to standards or monitored for the five-year success criteria period as would a typical stream restoration
proj ect.
Please do not hesitate to contact me if you should have any questions regarding this additional
information or if there is any way in which we can be of any further assistance to you.
