To whom it may concern:
The purpose of this letter is to notify the state of SCM Metal Products' intent to install a new process at our
facility. In 2016 I had submitted a permit renewal form for SCM Metal Products, Inc., permit No. NCS000050.
We have not received the renewed permit to date, and we are currently operating within the parameters of our
previous permit as instructed by the state. However, there is a plan to install a new process in June of this year
in which antimony ingots will be processed into antimony powder. We would like for the state to include this
process in our permit during the renewal process.
This process will include crushing, milling, and screening operations. The process will be located indoors in the
previous location of our tin powder production area, which is no longer in operation. The process will be
connected to a baghouse that will be located outside of the building as a control device for air quality. There are
no floor drains associated with this process that are connected to any of our storm drains. This process will be
located in the area of our storm water site reap that is directed to outfall #1. We do not anticipate any emissions
that would affect storm water quality. We will update our storm water pollution prevention plan accordingly to
include this process.
If you have any questions or require additional information please contact me at
[e-mail], and I can be reached direct at [phone].
Sincerely,
Westley Riscili

SIGNIFICANT CHANGES IN INDUSTRIAL ACTIVITIES
In March of 2013, the Brazing Manufacturing Process was moved into the main facility from an outside
building. This relocation of this process has helped eliminate the transfer of materials between buildings.
In December of 2013, the Tin Manufacturing Process was discontinued at the RTP facility. This product is now
produced at a sister facility.
Most additives are stored indoors, with the exception of some drums of flammable liquids, which SCM is
required to store outdoors by the fire department. These drums are stored on secondary containment pallets
and are covered with tarps.
SCM intends to install an Antimony Powder Process at our RTP facility. This process includes the crushing of
antimony ingots, and the grinding/milling and screening of antimony powder. This process is planned to be
installed in June of 2019. The Storm Water Pollution and Prevention Plan will be updated accordingly.
