Dear Mr. Cone:
The Wilmington Regional Office received previously requested information for the Stormwater
Management Permit Application for Cardinal Motors on March 10, 1997. A preliminary review of that
information has determined that the application is not complete. The following information is needed to
continue the stormwater review:
1. The sediment pit detail indicates a top width of 14, a bottom width of 5, a depth of 3' and a
2:1 slope on the sides. Using a 2:1 slope results in a top width of 17'. Please revise.
2. Even with the 17' width, the 1800 ft3 of storage provided in the basins is short by about 700
ft3. The volume required to be stored in the basins is calculated from the first inch over the
drainage area, just as any other control is designed. Please revise the basins to provide the
required storage.
3. The sediment pits are permanent stonnwater control devices and must be labelled as such.
4. Please show the relevant elevations for the basins on the detail. Show the top and bottom
elevations, the riser outlet structure elevations, pipe invert elevations, etc..

Dear Ms. Lewis:
In response to your February 26, 1997 letter, the following information is
provided (responses follow the order of your letter):
1. No on -off elevations are required. The pumping of stormwater in
this application is different from a typical sewage lift station design. A sump
pump will be provided in a junction box to pump stormwater at a calculated
rate to allow discharge from the storage area within the required two to five
day period. The sump pump is activated by a float switch attached directly to
it. When water is present, it will pump. When water is not present, the float
switch will deactivate the pump. Since the design is based on storing a
calculated volume of water, flows in excess or that calculated amount will
bypass once the storage volume is achieved. There are no on -off elevations
such as you would have with a sewage lift station.
2. Calculations for the sediment pit are included on the revised
drawing. The sediment basin has been revised showing dimensions and
depths.

We trust the above information answers your concerns. As you know, the
approval process for this project has taken an extraordinary amount of time.
Your assistance in review/approval as soon as possible would be greatly
appreciated. if there are further questions, please contact me at the above

Dear Ms. Lewis:
In response to your January 27, 1997 letter, the following information is
provided (responses follow the order of your letter):
1. The proposal has been modified to reflect use of an STC 1800
Model Stormceptor. This model stormceptor is capable of 85% TSS removal
for the drainage area designated. The following analysis is provided:
a.) Refer to Figure 6 (Stormceptor Sizing Guideline) in the Technical
Manual (page 19). To obtain 85% suspended solids removal, a Stormceptor
storage capacity of 175 cf/acre is required.
b.) Based on a 1.075 acre drainage area, the required storage capacity
is 188 cf/acre (1.075ac X 175 cf/acre).
c.) Using 188 cf as the required storage capacity for 85% suspended
solids removal, refer to Table 4 (Stormceptor Capacities) in the Technical
Manual (page 15). The STC 1800 Stormceptor has a sediment capacity of
195 cubic feet ( > 188 cf), adequate to provide 85% suspended solids
removal.

STORMWATER MANAGEMENT PLAN n E C E I V E D
CARDINAL MOTORS SITE lUuuf
WESTERN BLVD FEB 101997
JACKSONVILLE, N.C.
. PROJ k—Z8_ q(aU3�
NOTE: THIS IS A PROPOSED MODIFICATION TO A tirvD.
PREVIOUSLY PERMITTED STORMWATER MANAGEMENT
PLAN FOR THIS SITE.
The proposed site has been developed for use as a car dealership. Construction consists
of a building, paving, curbing, and landscaping. The site was previously permitted using
a combination of grass swales and dry detention for stormwater control. This
modification proposes to retain the permitted stormwater measures for the eastern
drainage area of the site, but to utilize a new product by Stormceptor for stormwater
control on the western drainage area of the site. This proposal to utilize the Stormceptor
product is based on the following:
1) Studies of the Stormceptor structure (1994, Ontario Ministry of Natural
Resources) show the device removed 80 to 95 % of all sediments.
2) The same study showed the Stormceptor has the added advantage of removing
60-80% of oil and grease and also removes 88% of the phosphorus load.
3) The Stormceptor structure is ideal for use in areas where land is unavailable
for more conventional wet detention ponds and other accepted methods.
4) The stormwater structure is easy to design and construct.
5) The percentage of annual flow being treated is 83 to 97% for impervious areas
of 2.5 acres or less (as in this case).
6) Cleaning and disposal costs are low. Maintenance is fast and efficient. By use
of grated inlets (as noted on the plans) control of large debris is provided. Maintenance
of the Stormceptor is generally done 1 time per year. Twelve inch inspection ports are
provided on the access way of the Stormceptor for maintenance purposes. Maintenance
is simple, quick and does not require physical entry into the unit.
7) The Stormceptor product has been used successfully in Maryland and other
parts of the country.

8) The Stormceptor product was recently approved and installed for use at a
McDonald's Site in James City. We have attached several documents that contain
additional information and test data regarding the Stormceptor. We feel, particularly on
this site, that this product provides a credible alternative for stormwater management.
Due to the limitations and advantages noted above, the owner is proposing the use of an
innovative design in accordance with Section .1008 of 15A NCAC 2H. Specifically, the
use of Stormceptors developed by Hydro Conduit (see attachment) is being proposed as
an alternative best management practice in accordance with North Carolina's Stormwater
Management rules. The Stormceptor is a new product designed to remove NPS pollution
and provide significant water quality control of urban and industrial non -point source
pollution. In addition to trapping and retaining urban pollutants, the Stormceptor device
includes a built-in diversion (by-pass) structure that allows the first flush 80% to 90% of
all rains to enter the treatment chamber, but diverts the problem flushing storms.
The stormwater design also provides for storage of the first V of rainfall and subsequent
discharge over a 2-5 day period. Storage is provided via 18" and 48" pipes buried below
the parking lot. Discharge over a 2-5 day period is provided by a sump pump. Storage
calculations are provided as follows:
Runoff From V Rainfall:
47,000SF x .9 x 1/12in/ft = 3,525 CF
75 LF of 18" Pipe: VOL. = (3.142) (.75) (75) = 133 CF
2
273 LF of 48" Pipe: VOL. = (3.142) (2.0) (275) = 3,456 CF
TOTAL STORAGE PROVIDED 3,589 CF
CALCULATE DISCHARGE RATE:
3,589 CF
Q2 =---------- = 0.021 CFS
172,000S
3,589 CF
Q5 =----------- = 0.008 CFS
432,000S
SET SUMP PUMP DISCHARGE RATE AT 0.02 CFS (9gpm)
USE MEYERS S-25 (1/4 HP SUBMERSIBLE SUMP PUMP)
SET DISCHARGE RATE AT 9 GPM

r fi''.

The Stormceptor device provides an economical, effective, extensively tested method of
treating runoff pollutants. Recent field tests of the Stormceptor structure by the Ontario
Ministry of Natural Resources found that the device removed 80 to 90% of all sediment;
60 to 80% of oil and grease; and removed 88% of the phosphorus load during wet
weather flows. Additional data and test results are attached for your review.
The western drainage area of the site has impervious area totalling 1.08 acres. Based on
recommended design criteria in the attached Technical Manual, the following
Stormceptor Device is recommended:
Stormeeptor STC 1800 (w/32" insert)
By-pass Flow - 27.6 cfs
Maximum treatment flowrate - 285 gal/min
The proposed Stormeeptor is rated by maximum GPM flowrate prior to bypassing.
Based on a V rainfall, the volume of runoff for the proposed area draining to the
Stormceptor is calculated as follows (assume 100% runoff):
Vol. = 1.08ac X 43,560ft/ac X 1 " X 1712" = 3920 of
Assuming a 1" rainfall over a two hour period, the following average discharge rate
would be developed from the drainage area:
3920 cf
DA 1: Q =---------- X 7.48 gal/cf= 244 gal/min
120 min
The expected peak flow from this site is calculated as follows:
Q = CIA = (.9) (7) (1.08) = 6.8 cfs
[a]IT4A!itT�IKY.
Refer to Technical Manual Figure 6 Page 19:
Stormceptor Sediment Storage Capacity to Achieve 85% SS Removal = 175 cf/ac
Minimum Storage Capacity = 175 cf/ac X 1.08 ac = 189 cf
Refer to Technical Manual Table 4- Page 15:
Use Stormceptor STC 1800 (195 of Sediment Capacity)
Based on Stormceptor Sizing Guidelines (see attached technical data), we propose
to use one model STC 1800 for the drainage area. Installation and maintenance would be
provided in accordance with manufacturer's recommendation. In comparison to the

above flow calculations, the Stormceptor (STC 1800) is capable of a maximum treatment
flowrate of 285 gal/min without bypassing, well above the calculated 244 gal/min
flowrate expected from a a typical 1", 2 hour storm. It can handle maximum by-pass
flows of 27.6 cfs, well above the expected peak flow of 6.8 cfs for this site. In addition,
it is capable of removing 85% of TSS.
We feel that the proposed Stormceptor product offers a credible option for stormwater
management and request that use of the product be approved for this location.

Dear Mr. Cone:
The Wilmington Regional Office received previously requested information for the modification to
the Stormwater Management Permit Application for Cardinal Motors on January 10, 1997. A preliminary
review of that information has determined that the application is not complete. The following information
is needed to continue the stormwater review:
1. The proposed design still does not address how the 85% minimum required TSS removal will
be achieved. The Stormwater Management Plan still only indicates a removal efficiency range
of 80% to 95%. Please indicate where in the literature it states that the Series 2400 will
remove a minimum of 85% TSS for a drainage area of 1.075 acres.
2. The previously approved sediment pit calculations were insufficient, but due to the generous
volume provided in the previously approved basins, the sediment pit was approved. Now that
the Stonnceptor is being used, excess volume is no longer available. The sediment pit area
must be enlarged or you may provide another Stormceptor unit for that runoff as well.
3. Please revise the Operation and Maintenance Plan to include the sediment pit maintenance,
if the sediment pit will be enlarged.
4. Delineate all wetlands on site, or note on the plans that none exist.

Dear Ms. Lewis:
In response to your November 21, 1996 letter, the following information is
provided (responses follow the order of your letter):
1. The design has been modified to provide storage for the first 1" of
rainfall with discharge between 2-5 days. Storage is provided by use of pipes
below grade in the parking lot.
2. The Stormceptor has been proven to be an effective stormwater
treatment device. Recent testing by the Ontario Ministry of Natural
Resources indicates the device removes 80-95% (mean of 87.5%) of all
sediment, 60-80% of oil and grease, and 88% of phosphorus load. Although
data that would support a guarantee of 85% tss removal is not available, data
is attached that indicates the device provides sediment control that on average
exceeds 85% - with the added benefit of oil, grease, and phosphorus removal.
Although no direct comparison to a conventional wet detention pond is
available, a case could be made that the Stormceptor product is
environmentally more effective than a detention pond.
3. Revised calculations are sealed.

Dear Mr. Cone:
The Wilmington Regional Office received a Stormwater Management Permit Application for Cardinal
Motors Expansion on November 12, 1996. A preliminary review of that information has determined that
the application is not complete. The following information is needed to continue the stormwater review:
1. Alternative design criteria located at NCAC 2H.1008 (h) (1) and (2) require demonstration
that either the 1" volume is detained for 2-5 days, or the post -development discharge rate is
equal to or less than the pre -development rate discharge for the 1 year, 24 hour storm
(approximately 3" of rain.).
2. Alternative design criteria also require that a minimum of 85% TSS be removed. The
narrative indicates that the lower threshold for the Stormceptor is 80%. How do you propose
to guarantee 85 %?
3. The calculations must be sealed.
4. The narrative submitted indicates that a building will be constructed. The plans and
application form indicate only parking lot to be constructed.
5. Delineate all wetlands on site, or note on the plans that none exist.
6. No additional information (ie., technical data) was submitted..

Here are the Stormceptor news flashes from around the world
8 Stormceptor has been selected for the Boston Central Artery/Tunnel Project, which was designed by
Bechtel/Parsons Brinkerhoff. Numerous federal, state and environmental commissions have
approved the use of Stormceptor for water quality control on the Boston Central Artery/Tunnel
Project which drains to the Charles River. A total of 20 units are planned for this large capital

Enclosed is summary information on Stormceptor. As the former Director of the State of Maryland's,
Sediment and Stormwater Administration, I am always looking for new, innovative and economical methods to
control nonpoint source (NPS) pollution. You may want to utilize Stormceptor water quality devices at new
and existing private and public development sites instead of concrete Oil -Grit Separators, especially in light of
the Metropolitan Washington Council of Governments' report (April 1993) that showed poor characteristics and
poor performance of Oil -Grit Separators.
Stormwater Management for water quality control and pretreatment can be a difficult and lengthy problem for
design professionals, a costly problem for developers and a bureaucratic headache for regulators. A new
innovative tool for the environmental design professional is now available to solve these problems.
Stormceptor has been extensively tested and monitored and many studies continue to be conducted in all parts
of the United States, all results have been positive. Stormceptor has received approval from many federal,
state and local agencies and is being used on large projects like the Boston Central Artery Project, The EPA
Resource Recovery Site in Stratford, Connecticut and for many small development projects throughout the
Chesapeake Bay Watershed and the United States.
Stormceptor is a precast structure that installs in a few hours and provides long term reliability and fits into a
new or existing storm drain system and effectively removes high percentages of oil, sediment and other urban
pollutants from storm water runoff. Its unique design prevents the resuspension or scouring of previously
collected pollutants, even during peak storm water flow periods. Yearly maintenance is simple, less frequent
and less costly than for all other BMP practices.
Stormceptor can be used as a Primary Water Quality Device, as a Pretreatment Device, as a Spill Control
Device, as a Coastal Zone Management Device or as an NPDES Stormwater Device. For additional technical
information contact me at Stormceptor Corporation at 1-800-763-4703 or Fax at 301-762-4190.

Subject Use of Stormceptor Units at Raymark
Dear Mr. Brunetti:
This letter is to confirm our earlier discussions concerning the use of Stormceptor Units at the
Raymark Industries Facility Superfund Site located in Stratford Connecticut.
The United States Environmental Protection Agency (EPA,) is currently involved in the
rernediation of the hazardous site conditions at the Raymark facilities. These efforts are being
conducted pursuant to the Comprehensive Environmental Responsive, Compensation, and
Liability Act (CERCLA) of 1980 as amended by the Superfund Amendment and Reauthorizadon
Act (SARA), more commonly know as "Superfund". As part of this effort, EFA as entered into
an Interagency Agreement (IAG) with the U.S. Army Corps of Engineers (Corps) to oversee the
re.mediation (a.k.a.: clean-up) activities. The Corps, in turn, as contracted with Foster Wheeler
Environmental Corporation (FWENI C) to perform the actual work.
As part of the work, FWENC will need to install a stormwater collection and management
system. It is my understanding that as part of this system Foster Wheeler has selected
approximately sixteen of Hydro Conduit's Stormceptor units to control oil and sediment resulting
from the site. Selection of the Stormceptor units was made in conjunction with technical
requirements and discussions. with the State's stormwater personnel.
As always, should you have any additional questions or issues be do not hesitate to contact me.

Water Management and Water Quality Controls hap: //v .srormcepror.ca/
Enclosed is the latest information on Stormceptor®. As the former Director of Maryland's, Sediment and
Stormwater Administration, I am always looking for new, innovative and economical methods to control
nonpoint source (NPS) pollution. The new federal NPDES stormwater regulations, state and local stormwater
laws, sensitive area laws and coastal zone management laws are requiring us to utilize every opportunity to
reduce and clean-up nonpoint source runoff from all new and existing land uses as part of our "Pollution
Prevention" strategies. I recently became associated with a new product that was developed in Canada called
Stormceptor which can greatly reduce NPS pollution and I think will excite you as much as it has excited me.
This device provides significant water quality control of urban and industrial nonpoint source pollution. The
application of Stormceptor at new and existing private and public development sites rather than using the
concrete oil/grit separator or sand filter should be evaluated carefully, especially in light of the Metropolitan
Washington Council of Governments' report (April 1993) on Oil -Grit Separators. I am enclosing some
information on the Stormceptor. for your evaluation. This device has and is being approved by the District
of Columbia, in Virginia by; Falls Church, Fairfax, Alexandria and Herndon: in Maryland by;
Annapolis and Baltimore City and Montgomery, Prince Georges, Anne Arundel, Baltimore, Howard,
Carroll, Harford, Cecil, Allegany and Frederick Counties for numerous project sites.
The Stormceptor is a unique patented design that traps and retains urban NPS pollutants and is installed at
over 550 sites in the Toronto, Brampton, Ottawa and Winnipeg areas in Canada and at 150 sites in the
Washington -Baltimore Region. The Stormceptor device, includes a built-in diversion (by-pass) structure that
allows the first flush (80% to 90% of all rain hours) to enter the treatment chamber, but diverts the problem
causing flushing storms (10% to.20% of all rain hours) around the treatment chamber. The diversion feature
allows the unit to have a smaller volume as compared to flush through devices. A half inch rainfall (which
is greater than 60% to 70% of all storm events), six hour storm (average storm duration for all storm events) is
fully treated through the device. Long term phosphorus removal for Stormceptor is estimated to be 25% or
greater.
The Stormceptor design also includes a water locking feature that prevents trapped hydrocarbons (VOC's,
floating oils and gasoline) from being resuspended or easily volatilizing into the atmosphere. In urban areas it is
estimated that millions of gallons of petroleum products are washed into streams and creeks each year.
The Stormceptor is made as a precast concrete structure, which appears and installs like a precast concrete
manhole, a fiberglass version is also available. The Stormceptor itself can be reused if the site application
changes, such as when a temporary parking lot is built prior to the construction of a permanent building or
structure. The Stormceptor design flexibility allows it to be used in -place of a manhole or bend structure and
in situations where drainage grade lines are restricted due to topography, high groundwater or utility conflicts.
The unit needs only 1 inch of fall through the structure.

The Stormceptor has undergone extensive testing at Canada's National Water Research Institute in Burlington,
Ontario (Canada's largest fresh water research facility) and Final Reports are now complete, also a Computer
Modeling Report has been completed. The Final Reports and the Modeling Report are available from our office,
upon request.
On the basis of the Institute's laboratory data (1993) the unit appears to have high trapping effectiveness for
oils (nearly 100%) and solids (10% to 80% for grit and sand, and 30% to 50% for silt and loam) and retains
the materials without resuspension and mixing. The unit works best when large debris (large jugs, lumber,
bundles of paper, etc.) are screened out of the stormwater entering the unit. The Stormceptor can be installed
in traffic or non -traffic bearing areas. Recently (1994), the Ontario Ministry of Natural Resources
conducted initial field monitoring of the Stormceptor structure and found it removed 80 to 95% of all
sediment; 60 to 80% of oil and grease; and removed 88% of the phosphorous load, during wet weather
flows. A copy of this report is available upon request
The Stormceptor owners and I have met with numerous stormwater officials in the Washington -Baltimore
Metropolitan Area. The counties and cities in this area are now approving the use of the Stormceptor when
submitted. The installation is much simpler than any of the other types of separator devices, since it has modular
components, and normal installation takes several hours to 1/2 a day for a concrete unit.
The cost of the unit has recently been set and the total cost of the Stormceptor (unit, connectors, frame and
cover, extension collar and steps) is significantly less than an Oil -Grit Separator or Sand Filter. A typical unit
treats a 1/2 to 5 acres of impervious drainage area. Units for larger and smaller applications (1/2 to 11.25
acres), as well as specialized designs, are available. The Stormceptor also provides long term reliability and
will not become a pollution source, as compared to other types of water quality devices being used.
The Stormceptor like all water quality separators requires periodic maintenance. Typical water quality inlet
maintenance is recommended to be done 4 or more times a year, but the Stormceptor requires less frequent
maintenance due to its unique design. Maintenance of the Stormceptor is generally done 1 time a year.
Maintenance is simple, quick and does not require physical entry into the unit, using conventional vacuum truck
equipment.
I would like to request that your agency or firm carefully evaluate the use of the Stormceptor System for
Water Quality Treatment and when found acceptable to utilize this innovative device. I hope you find this
information useful and that you will approve the use of the Stormceptor device for the many private and public
projects you plan, design and approve. So that everyone hears about Stormceptor we ask that you share this
information with your colleagues. If you need further assistance, additional information, a slide presentation or a
short video tape, do not hesitate to call me personally at [phone] or 1-800-762-4703.

DIVISION OF ENVIRONMENTAL MANAGEMENT
MEMO TO: Rick Shiver
FROM: Linda Lewis
DATE: September 18, 1996
SUBJECT: SW8 960326 Cardinal Motors-Onslow County
SW8 960210 Golden Corral -Carteret County
Rick,
On September 16, 1996, I visited the Golden Corral site in Morehead City. The project was
approved as a combination of a redeveloped site and a detention pond. The existing impervious area was
allowed to sheet flow as previously existed, with the excess impervious area collected and sent to a
detention pond. Upon inspection, I discovered that an additional parking bay, approximately 60' x 211'
had been added to the project, and this addition had not been sent to this Office for review. Pending a
review of the revised project, it appears that a portion of the additional parking is collected and sent to
the pond, while the remaining area is collected and sent into the existing street system.
The Engineer's Certification for the Golden Corral has not been received. A Notice of Violation
was issued to Mr. Ronnie Smith of the Outer Banks Development Corporation on September 17, 1996,
copied to both Mr. Fred Cone, P.E., and Mr. John Pierce, R.L.S.
As concerns Cardinal Motors, Mr. Pierce called me about 2 weeks ago and spoke about the
possibility of using "StormCeptors" for the Cardinal Motors site. I questioned Mr. Pierce as to why the
approved stonnwater controls had not been constructed yet, since the project had been approved on May
29, 1996, over three months ago. I have neither visited the site since approval, nor received a revised
application for the Cardinal Motors site. The Engineer's Certification has not been received due to the
fact that the system has not been constructed.
In the case of the Golden Corral, Mr. Pierce has obviously misled this Office as to the scope of
the project. The detention pond is undersized for the drainage area, therefore water quality is an issue.
In the case of Cardinal Motors, it will be difficult to prove Mr. Pierce's involvement in any decisions
concerning delay of construction of the permitted stormwater system that the owner of the site has made
concerning compliance with his permit.

Mr. Scott Monteith, Director

Toronto, Ontario M9C 5K1
Dear Mr, Monteith:
The Peace Bridge Authority has recently completed re -construction of our Canadian Truck
Processing yard, which includes a storm water management system consisting of standard catch
basins, a series of stormceptor tanks and finally motorized sluice gates complete with remote control.
August 19, 1996 a truck sent into Canada Customs for Secondary Inspe"ion developed an oil leak
which ran into our storm drainage system.
The sources of the leak was quickly cut off however some of the oil ran into our storm system and
therein was trapped by our newly installed stormceptor tanks.
In the case of this spill the weather conditions were dry and the stormceptor tanks were of a size to
compiete'v contain the oil leak, without the use of our sluice bates.
The spill was quickly cleaned up including the stormceptor tanks, thus allowing reuse of the parking
area (note: this parking lot is congested at the best of times). To say the least we were pleased at the
ease of cleanup and our return to normal operations.
very truly yours,
Robert A. Smith
Construction Superintendent
