I would like to see if we could do the call Tuesday at 9 am rather than 10 am if that works for
you. See below for some additional information regrading your comments.
GENERAL OVERVIEW:
. A reminder to everyone that this stormwater plan is to fulfill the requirements of a 401
Certification issued for this project on February 17, 2014. This certification can be viewed
at: http://its.enr.state.nc.us/WebLink8/DocView.aspx?id=217849. My understanding is that
there is currently a Notice of Violation for this project due to use of the facility before the
implementation of a stormwater management plan as well as deposition of sediment into the
receiving stream. Perhaps Chuck Cranford from the Asheville Regional Office can elaborate
on this when he returns next week.
. You are also requesting that this project be considered as a submittal to the PEP program.
. This submittal must be sufficient to address the programmatic issues associated with the
401 Certification program, resolution of the Notice of Violation and the requirements of the
PEP.

The site currently is under a Notice of Violation. A response was filed with Chuck August 25th. The
sedimentation cleanup is approximately 75% completely and will be completed later this week or
early next week. The site is still very much a construction site with limited asphalt and grading still
active. They did have some shows earlier in July as an introduction to the project and to meet
licensing requirements. It is our expectation that the treatment systems will be installed
immediately upon approval. We are requesting that the project be considered as a submittal to the
PEP program.
PEP REQUIREMENTS:
. Please provide a design narrative that states the design objective, summarizes in words the
design approach, and concludes with the assertion that the design is compliant with the
relevant rules?
• Please provide a QAPP for our review and a commitment to stay the course over 12 months
of testing.
. Pleae provide an agreement to replace or tweak the Isolator Rows if they don't work to
achieve 85% TSS or an effluent concentration of 20 mg/L or less.
We will provide the additional information requested above in conjunction with ADS.
PLEASE EXPLAIN:
Which portions of the site are already built and which areas are paved versus
gravel.
How the Notice of Violation will be resolved and the stream will be restored. It
sounds like the site has caused a significant amount of sediment to be deposited in
the stream.
Please also explain how the Isolator Row devices will be protected from sediment
after their installation, particularly the devices that will be located downslope of
permanently unvegetated areas like horse rings and trails.
Which portions of the stormwater plan you are requesting approval for now and
which areas will be designed/built in the future (if any).

I will provide you with a drawing that indicates what is built and where construction is
continuing. The NOV is in the process of being resolved now. The drawing will indicate what we
are requesting approval for now and what is for the future. Additional information will be provided
to address your other questions.
CALCULATIONS:
Flow calculations were provided for every catch basin and pipe in the storm
drainage network. However, for every drainage area, C was estimated to be 0.5 and
for many inlets, the storm intensity was given to be 0 inch/hour. Please double-
check.
Please provide calculations for the sizing of the Isolator Row systems.
We will review this immediately.
PLANS — PLEASE SHOW:
Drainage easements or deed restrictions for the stormwater control measures.
How the Isolator Row systems will be accessed.
Clear details of the Isolator Row systems, including inlet and outlet details and
elevations.
Dimensions, elevations and pipe sizes for every stormwater diversion device that
will be used with supporting calculations.
• A construction sequence.
We will provide this shortly along with the items below.
MAINTENANCE & MONITORING
Please provide a signed and notarized Operation & Maintenance Agreement for
the stormwater control measures.
4

Please provide a monitoring plan for one of the Isolator Row systems, including
the equipment, procedures and frequencies for cleaning the devices.
Please provide a signed and notarized agreement stating that the Isolator Row
systems will be replaced with another stormwater control measure if monitoring data
show that they are not working effectively.
