Subject: Draft NPDES Stormwater Permit
Permit No. NCS000373

Dear Mr. Matthews:
Enclosed with this letter is a copy of the draft stormwater permit for your facility. Please review the draft
very carefully to ensure thorough understanding of the conditions and requirements it contains.
The draft permit contains the following significant changes from this facility's current permit:
• Total Suspended Solids (TSS) monitoring has been removed from Part II, Sec. B.
• All analytical monitoring has changed from annual to semi-annual (once in the spring and once
in the fall). This change is based on the Division's revised strategy for stormwater monitoring in
renewal permits and makes stormwater discharge sampling frequency consistent with qualitative
monitoring. Please note that analytical monitoring mast still be performed during a
representative storm event (whereas qualitative does not).
Instead of "cut-off concentrations," the Division has incorporated benchmark values into the
permit. These benchmarks are not permit limits but should be used as guidelines for your
facility's Stormwater Pollution Prevention Plan (SPPP). If any measurements exceed benchmark
values, your facility should evaluate the effectiveness of its Best Management Practices (BMPs),
review and/or update its SPPP, and document any efforts to address stormwater contamination
(see Part 11, Sections B and D).
Total Flow monitoring has been removed. The permit still requires Total Rainfall amount and
Rainfall Event Duration be recorded for each sampling event. This change is also based on the
Division's revised strategy for stormwater monitoring in renewal permits. Please note that the
Stormwater Pollution Prevention Plan (SPPP) site map must include drainage area for each
outfall in acres and the percentage of each drainage area that is impervious (see Part 11, Sec. A).
Please submit any comments to me no later than thirty (30) days following your receipt of the draft.
Comments should be sent to the address listed at the bottom of this page. If no adverse comments are
received from the public or from you, this permit will likely be issued in about two months.
If you have any questions or comments concerning this draft permit, contact me at [phone] x 529 or
[e-mail].

2. Stormwater Management Plan. The stormwater management plan shall contain a
narrative description of the materials management practices employed which control or
minimize the exposure of significant materials to stormwater, including structural and
nonstructural measures. The stormwater management plan, at a minimum, shall
incorporate the following:
a. Feasibility Study. A review of the technical and economic feasibility of changing
the methods of operations and/or storage practices to eliminate or reduce exposure
of materials and processes to stormwater. Wherever practical, the permittee shall
prevent exposure of all storage areas, material handling operations, and
manufacturing or fueling operations. In areas where elimination of exposure is
not practical, the stormwater management plan shall document the feasibility of
diverting the stormwater runoff away from areas of potential contamination.
b. Secondary Containment Schedule. A'sche"dule to pr de secondary containment
for bulk storage of liquid materials, storage of Section 313 of Title III of the
Superfund Amendments and Reauthorization Act (SARA) water priority
chemicals, or storage of hazardous substances to prevent leaks and spills from

connected directly to storm I atericonveyance systems, the connection shall be
controlled by manually activated` elves or other similar devices [which shall be
secured with a locking gmechanism] and any stormwater that accumulates in the
containment area shall beat a minimum visually observed for color, foam, outfall
staining, visible sheens and'dry weather flow, prior to release of the accumulated
stormwater. Accumulated stormwater shall be released if found to be
uncontaminated by the material stored within the containment area. Records
\Z._ </
documenting theindividual making the observation, the description of the
accumulated stormwater and the date and time of the release shall be kept for a
period of five years.
C. BMP Summary. A narrative description shall be.provided of Best Management
Practices (BMPs) to be considered such as, but not limited to, oil and grease
separation, debris control, vegetative filter strips, infiltration and stormwater
detention or retention, where necessary. The need for structural BMPs shall be

of pollutants to stormwater discharges and data collected through monitoring of
stormwater discharges.
Spill Prevention and Response Plan. The Spill Prevention and Response Plan (SPRP)
shall incorporate an assessment of potential pollutant sources based on a materials
inventory of the facility. Facility personnel (or team) responsible for implementing the
SPRP shall be identified. A responsible person shall be on -site at all times during facility
operations that have the potential to contaminate stormwater runoff through spills or
exposure of materials associated with the facility operations. The SPRP must be site
stormwater specific. Therefore, a SPCC plan may be a component of the SPRP, but may
not be sufficient to completely address the stormwater aspects of the SPRP. The common
elements of the SPCC with the SPRP may be incorporated by reference into the SPRP.
