Attention: Mr. Bradley Bennett
This letter is to follow-up on your conversation with Grant Oxendine, our new Site EHS
manager, on April 23, 2015. As discussed during that call, the Lumberton Cellulose LLC Mill has
completed a thorough review and update of its existing SPPP. This has resulted in the revision
of several documents that were submitted as part of the permit renewal application that was
mailed to your office on March 3, 2015. As such, we are providing the following revised
documents to amend our previously submitted permit renewal application and to promptly
submit such newly identified information in accordance with Part III.E.11 of our current NPDES
permit:
A new Site Map from the updated SPPP (attached as Figure B-2). We are adding two
new outfalls identified as outfalls No. 9 and No. 10, to our storm water
sampling/monitoring plan. As a result of adding these new outfalls, we have updated
the drainage area descriptions in Table 1 of our updated SPPP accordingly. In addition,
we have also revised our sampling locations for outfalls Nos. 2 and 4. Current conditions
around these discharge points have rendered them inaccessible during wet periods due
to sedimentation, vegetation growth and submerged discharge conditions. As a result,
our updated SPPP shows that we will sample these locations at the closest catch basins
upstream of these outfalls. This sampling strategy will also be applied to the new outfall
identified as No. 9.
2. A new Stormwater Pollution Prevention Plan Development and Implementation
Certification.

Dear Mr. Bennett:
This letter is to follow-up on your conversation with Grant Oxendine, our new Site EHS
manager, on April 23, 2015. As discussed during that call, the Lumberton Cellulose LLC Mill has
completed a thorough review and update of its existing SPPP. This has resulted in the revision
of several documents that were submitted as part of the permit renewal application that was
mailed to your office on March 3, 2015. As such, we are providing the following revised
documents to amend our previously submitted permit renewal application and to promptly
submit such newly identified information in accordance with Part III.E.11 of our current NPDES
permit:
A new Site Map from the updated SPPP (attached as Figure B-2). We are adding two
new outfalls identified as outfalls No. 9 and No. 10, to our storm water
sampling/monitoring plan. As a result of adding these new outfalls, we have updated
the drainage area descriptions in Table 1 of our updated SPPP accordingly. In addition,
we have also revised our sampling locations for outfalls Nos. 2 and 4. Current conditions
around these discharge points have rendered them inaccessible during wet periods due
to sedimentation, vegetation growth and submerged discharge conditions. As a result,
our updated SPPP shows that we will sample these locations at the closest catch basins
upstream of these outfalls. This sampling strategy will also be applied to the new outfall
identified as No. 9.

Certification.

Also, on April 24, 2014, the Mill reported total suspended solids (TSS) benchmark exceedances
for Outfalls No. 6 and No. 7 and subsequently notified your regional office about the
implementation of several structural improvements to the stormwater management system,
which included:
• The installation of curbing around the storm drains associated with Outfalls 6 and 7, and
• The installation and maintenance of filters in the storm drains associated with Outfalls 6
and 7.
Since that time, we concluded that these two structural changes did not provide a significant
benefit and did not warrant the associated maintenance burdens. The Mill discontinued the use
of these two structural changes early in 2015 and TSS results have remained well below the
benchmark values. The other stormwater management system improvements previously
reported will be maintained such as the installation of a retainer wall to prevent sediment from
washing down from an upslope area and to promote the growth of grass in that area.
Thank you for your support in this matter. Should you have any questions, please feel free to
contact me at 910-737-3231 or Grant Oxendine, our EHS Manager, at 910-737-3283.
Sincerely,
Chuck Oxendine
General Manager
