Attachments State SW Plan Revision Submittal Package to Linda Lewis - 07-06-07 pdf
Hi Steve,
I'm still digging for some additional documentation and will have to pull some of our files out of archive but I found the
following email in my archives for 2007
We originally submitted this as a plan revision to Mr Norris's modification to the Odell Williamson stormwater permit to
include the Athletics & Aquatics Center permit # SW8 910501
In the modification for the Aquatics & Athletic Center, Mr Norris had 40,921sf of future impervious allotted Later we filed
a plan revision with Linda (see below & attached) which used 25,846sf of the future allotment leaving a balance of
15,075sf of future allotment At that time, plan revisions were handled by a simple submittal of an updated plan and
evidence that we were still in conformity with the current permit, i e revised calculations This should bring us up to the
current proposed modification
As I said I am going to dig through our files in the archives and get copies of the permits etc for our meeting on the 29`"
but this is what I could find at my fingertips Hopefully this helps
Thanks

Subject RE BCC INFRASTRUCTURE PLANS
Dean,
I reviewed the drawings, the permit, and the calculations and did not find any reference to this drawing, sealed by Phil
Norris on 7/5/07, or to the subject "existing parking lot" The latest modification and plans are dated 12/22/06
Therefore, the permittee is in violation for failure to modify the permit before installing impervious area To correct this
problem, you need to include the parking lot in your accounting of impervious for this modification Why did the
parking area go up by 25,846 sf, as shown on the application page 3 of 4?
Also, please provide the additional information requested by Aisha on April 20, updated as follows
-1 Please provide area of the bottom of the pond
�2 Please provide details for additional buildings, parking, sidewalks, future area, and any other BUA on the plans,
includin.- widths, radii, dimensions, and slopes
-"3 Please provide hatching to delineate what areas are asphalt, concrete, etc , and note this on the legend
4Please show all existing drainage (piping, swales, ditches, etc ) as well as clearly delineating all drainage areas
✓ 5 Please show the aimensioned project / property boundary line with bearings and distances
We request that you submit your response no later than June 29, 2010, or the application will be returned as
incomplete
If you have any questions, please don't hesitate to call

Hello Dean,
I'm sending this reply to my coworker Steve Pusey because he has inherited this project from me as
a result of my position being eliminated effective 7/8/10 due to a reduction In force caused by the
worst state budget In about 30 years

He will be the one preparing a response for you once he has had a chance to look at the project, and
any future correspondence regarding this project should be directed toward him as well
Take care,

College — Odell Williamson Auditorium / Athletic
The Wilmington Regional Office received and accepted a modified State Stormwater
Management Permit Application for Brunswick Community College — Odell Williamson
Auditorium / Athletic Field Addition on March 5, 2010 A preliminary in-depth review of
that information has determined that the application is not complete The following
information is needed to continue the stormwater review
1 Please provide the area of the bottom of the pond Despite this not having
been a required field when the permit was initially obtained, it is a
measurement that should be readily available to provide
,/ 2 Please provide details for all roads, parking, and other BUA on the plans,
/� including widths, radii, dimensions, and slopes The areas provided are
difficult to verify without this information In particular there is a parking lot
labeled "Existing Parking Lot' that is located Northwest of the pond, that does
not appear to have been incorporated as a modification previously

NKT Project No 10004

11/JC7cT.A190q
DESCRIPTION
The project site is a 163 8 acre tract located in Supply, NC on the Brunswick
Community College Campus The sods of the site consist of lightly vegetated -
moderately wooded - sandy - topsoil and grades ranging from 0% to 5%
Approximately 10 acres will be graded to allow construction of tennis courts and
baseball Field The runoff from the site is estimated using the rational method 10-year
design storm and rainfall data for the area Construction is scheduled to begin as soon
as all permits and approvals are obtained
The project consists of new tennis courts and baseball field Approximately 10
acres will be disturbed and 1 52 acres (15 2%) will be covered by impervious surfaces
EROSION CONTROL MEASURES
The attached plans and specifications outline the requirements for erosion
control measures Silt fencing will be provided along each side of the entrance drive
where stormwater would be expected to sheet flow from disturbed areas directly to
adjacent property Gravel check dams will not be provided unless the Contractor has to
temporarily discharge into an open ditch instead of the proposed storm drain outfall
The detention pond will be used as a silt basin during construction and restored to its
design contours prior to completion A gravel construction entrance will be constructed
adjacent to the tennis courts along College Road entrance Maintenance will be
provided by the grading contractor and developer
STORMWATER MANAGEMENT MEASURES
The project site is located in Brunswick County Land disturbing on the site will
exceed one acre, which requires the site to comply with the Brunswick County and ,
State Regulations The stormwater runoff from the development will be directed to the
Odell Williamson Auditorium stormwater detention pond The stormwater detention
pond was designed to accommodate this site at 49% impervious area lot coverage
CONSTRUCTION SEQUENCE
The Contractor will install the gravel construction entrance and silt fence prior to
beginning any clearing and grading operations Additional silt fence will be installed
when and if conditions warrant during construction The detention pond/silt basin will
be constructed immediately after that portion of the site is cleared, and outlet structure

EROSION CONTROL NOTES AND MAINTENANCE PLAN
1 All erosion and sediment control measures will be checked for stability and
operation following every runoff -producing rainfall, but in no case, less than once
every week and within 24 hours of every half -inch rainfall
2 All points of egress will have construction entrances that will be periodically top -
dressed with an additional 2 inches of #4 stone to maintain proper depth They
will be maintained in a condition to prevent mud or sediment from leaving the
site Immediately remove objectionable material spilled washed or tracked onto
the construction entrance or roadways
3 Sediment will be removed from hardware cloth and gravel inlet protection, block
and gravel inlet protection, rock doughnut inlet protection and rock pipe inlet
protection when the designed storage capacity has been half filled with
sediment Rock will be cleaned or replaced when the sediment pool no longer
drains as designed Debris will be removed from the rock and hardware cloth to
allow proper drainage Silt sacks will be emptied once a week and after every
ram event Sediment will be removed from around beaver dams, dandy sacks
and socks once a week and after every rain event
4 Diversion ditches will be cleaned out immediately to remove sediment or
obstructions from the flow area The diversion ridges will also be repaired
Swales must be temporarily stabilized within 21 calendar days of cease of any
phase of activity associated with a swale
5 Sediment will be removed from behind the sediment fence when it becomes half
filled The sediment fence will be repaired as necessary to maintain a barrier
Stakes must be steel Stake spacing will be 6 feet max with the use of extra
strength fabric, without wire backing Stake spacing will be 8 feet max when
standard strength fabric and wire backing are used If rock filters are designed at
low points in the sediment fence, the rock will be repaired or replaced if it
becomes half -full of sediment, no longer drams as designed or is damaged
6 Sediment will be removed from sediment traps when the designed storage
capacity has been half filled with sediment The rock will be cleaned or replaced
when the sediment pool no longer drams or when the rock is dislodged Baffles
will be repaired or replaced if they collapse, tear, decompose or become
ineffective They will be replaced promptly Sediment will be removed when
deposits reach half the height of the 15t baffle Floating skimmers will be
inspected and kept clean weekly
7 Sediment will be removed from the sediment basin when the design storage
capacity has been half filled with sediment Rock will be cleaned or replaced
when the sediment pool no longer drains or if the rock is dislodged Baffles will

be repaired or replaced if they collapse, tear, decompose or become ineffective
They will be replaced promptly Sediment will be removed from baffles when
deposits reach half the height of the 1st baffle Floating skimmers will be
inspected weekly and will be kept clean
8 All seeded areas will be fertilized, reseeded as necessary and mulched
according to specifications in the vegetative plan to maintain a vigorous, dense
vegetative cover All slopes will be stabilized within 21 calendar days All other
areas will be stabilized within 15 working days
9 Flocculants will be used to address turbidity issues The pumps, tanks, hoses
and inject systems will be checked for problems or turbid discharges daily

Subject. RE Stormwater question
Jody
Under Section 2 (d)(5) of Session Law 2008-211, which replaced Section 1005 in the stormwater rules, minor
modifications to a project are exempt from having to comply with the newer rules

A minor modification in the 2008 rules is defined as one that does not increase the net amount of built -upon
area or does not increase the overall size of the previously permitted stormwater controls
Because you have increased the drainage area, and will I assume, have more BLIA, that BLIA has to be
accounted for at the newer 2008 applicable design storm The old existing BLIA would continue to use the
previously permitted design storm However, if a previously permitted pond can accommodate that additional
BLIA (both in the pond area and volume) without having to be "increased" in size, i e , no enlargement of the
surface area is needed or the pond doesn't have to be deepened) then the pond doesn't have to provide all the
newer bells and whistles like forebays and vegetated shelves Tweaking the elevations of the orifice and
temporary pool slightly, without having to excavate the pond, to gain extra area and/or design volume is OK
If you have to increase the pond surface area via excavation, or deepen the pond, or if the existing elevations
had to be more than just "tweaked" a bit, then the pond would have to be redesigned using average depth, and
would need a forebay and a vegetated shelf if neither was present or if either was not sized per today's
standards For example the vegetated shelf slope was 6 1 and there was no minimum specified width in 1995,
so any existing ponds with a shelf slope at 6 1 or a shelf width less than 10', would be required to now provide
a 10 1 slope and a 10' shelf width
Another point of confusion is the difference between a minor modification under the 2008 rules and a minor
modification for Express The Express program used the term minor modification first to determine what fee to
charge "minor' modifications of projects The term minor modification under the 2008 rules is only to determine
if a project modification can be permitted under the rule it was previously permitted under or not You can see
how this might be confusing Because you're adding more drainage area and more BLIA to an existing pond,
the project is a full modification from the standpoint of the Express fee ($4000 00) The fee in the regular
program for this modification is the standard $505 00

Hi Linda,
I hope you are doing well on this soggy day I have a stormwater question for you
Phil and John Tunstall both have projects coming up that have old existing permitted ponds designed for the 1" storm
Both of these projects will require that we add additional drainage area to each pond Both ponds do not appear to be to
the current cross sectional requirements It appears that the additional volume created by the additional drainage area can
be accommodated by the pond with an adjustment to the outlet structure Will this be acceptable? When would an
upgrade to the cross section typically be required

Thanks,
Jody Bland

The files you attached are the submittal I received on July 6 In an email to Joe
dated July 19, 2007, I indicated that I was confused by that July 6 submittal
because it appeared to propose new ponds, but did not have an application or a
check with it In response, you indicated that I had inadvertently received a full
set of plans when I was supposed to receive plans for the new parking lot only
Additionally, you indicated that a second package for the new ponds had been
submitted a few days later The follow-up submittal is the package that has not
been received There is no record of receiving it at the front desk Was the second
package mailed or hand -delivered? What day was it delivered? Did it have a check
and a completed application with it for the new ponds If so, has the check
cleared> If it has cleared, please give me the permit number from that check

parking lot We submitted that revision letter on 7th and the a few days
later we submitted a full application package with all the necessary info
for the two new ponds on the 9th which will require a full review So please
excuse our goof and just pay attention to the additional impervious Let me
know if you need anything
