Re: Bermuda Bay Owners Association II
Dear Crouse:
Brian S. Edlin
[e-mail]
Fax:[phone]
As you know, this Firm represents the interest of Bermuda Bay Owners Association I1
("Association"). A few weeks ago, I forwarded you the Stormwater Management System
Maintenance Compliance Inspections (NCDEQ Permit #SW7040910) report ("the Report").
My understanding is that the Stormwater devices are in need of maintenance. Your clients,
BB Southampton Mews, LLC and BB Hamilton Cay took assignments of declarant rights at
various times. For instance, BB Southampton Mews, LLC agreed to "accepted such transfer and
assume the obligations of `Declarant"' under the Declaration of Devonshire Place Condominium
recorded at book 1648, page 13 of the Dare County Register of Deeds. BB Hamilton Cay, LLC
agreed to "accepted such transfer and assume the obligations of `Declarant"' under the Declaration
of Hamilton Cay Condominium recorded at book 1709, page 133 of the Dare County Register of
Deeds.
The Bermuda Bay development is less than 50% built -out. And, under N.C.G.S. §143-
214.7 (c2), we do not believe the permit for these devices should therefore be transferred to the
Association now. Further, some of the areas identified on the Report are not formally part of
Bermuda Bay in any event. Therefore, we believe your clients have responsibility for the items
mentioned in the Report. As I understand it, the permit needs to be renewed 15 October 2018, so
please review and contact me to discuss at your earliest convenience.
Sincerely,
AN PRICE WALL GRAY JONES & CARLTON

Re: Bermuda Bay - Stormwater Management System
My File No. 105 89-013
Dear Brian:
Phone [phone]
Fax [phone]
I am in receipt of your letter dated July 16, 2018. I apologize for the delay in responding.
I think the most important operative fact is that, at this stage, and for the last number of years,
it is my understanding that the Stormwater Permit No. SW7040910 is in the name of the Bermuda
Bad' Owners Association. As the permitee, your client has agreed to maintain all of the Stormwater
Management Facilities. It is your client that is responsible to the State of North Carolina for the
proper maintenance, repair and management of the Stormwater Management Facilities.
To be candid, I am not sure I understand your argument pursuant to N. C.G.S. § 143-214.7(c2).
I certainly acknowledge that portions of the existing Stormwater Management Facilities are located
on properties owned by my client. However, your client is the permitee. The fact that Bermuda Bay
Development is less than. 50% built out is immaterial. Your client requested and obtained a transfer
of the original permit into their name. N.C.G.S. §143-214.7(c2) is not applicable.
Your letter was unclear, but I am assuming that you are not arguing that my client has any
responsibility for issues concerning the Stormwater Management Facilities on lands that are not
owned by my client. If I understand your argument to be that since we own lands upon which
portions of the existing Stormwater Management Facilities are located, we therefore have an
obligation to maintain those items. Certainly, we are not the only party that obtained an assignment
of Declarant Rights. Furthermore, based on your argument that we have an obligation to maintain
those Stormwater Management Facilities, does that also mean we have the right to remove them

from our property?
Let me also refer you to the original Declaration for Bermuda Bay, as recorded in Deed Book
1648,Page 10, as amended, hereinafter the "Declaration". Section 7.1 of the Declaration provides
in part "The Association shall be responsible for management and Upkeep of all of the Common
Elements, the cost of which shall be assessed against all lots as a common expense."
The Declaration defines the term"Upkeep" to mean care, inspection, maintenance, operation,
repair, repainting, remodeling, restoration, improvement, renovation, alteration, replacement and
reconstruction.
Further, under the Definitions, Section 1.1 defines the term "Common Element" to mean,
among other items, "the Permit or Permits for stormwater facility assigned by the Declarant to the
Association or otherwise procured or acquired by the Association [emphasis added]. Your client
procured or acquired the permit. Therefore, it is a Common Element. Therefore, your client is
responsible for its upkeep.
If you will farther review Article 8 dealing with transfer of the permit and responsibilities,
it clearly indicates that "from and after the transfer of the permit from the Declarant to the
Association, the oversight, supervision, management and administration of the permit shall be the
sole responsibility of the Association. The Association's duties with respect to the permit shall be
carried out in accordance with the terms of the Association documents and the permit." Articles 8
clearly indicates that the transfer of the permit to the Association could occur prior to the total build
out and therefore, the Association would have an obligation to maintain all of the Stormwater
Management Facilities, irrespective if those lands were still owned by the original developer.
Therefore, the assertion that my clients have responsibility for the items mentioned in the
report is rejected.
With best wishes, I am
C sally yo ,

RE: [External] FW: Bermuda Bay; File No. 10589-013 : SW7040910
Roger,
This pertains to the Declarant transfer from the original development. It is probably why our letter was answered how it
was. The declarant went bankruptcy. The HOA in the transfer no longer exists and the declarant responsibilities were
moved to the new owners through purchase of the properties we talk about in our letter. It is our contention that the
developers, until their properties are developed, are responsible for maintenance until the 50% development of the
PUD. There is no transfer of the maintenance responsibility to the current HOA we can find. How does the state look
upon bankruptcy issues such as this and follow on responsibilities? As stated in the letter, we do not own the land upon
which the majority of storm water management facilities exist. The declarant, Mr Anderson, owned the land and
therefore could maintain the areas. Owners should maintain their properties. We are in a trespass situation should we
maintain their properties as we have no easements associated with these lands.

Stormwater Management Permit SW7040910
Sunset Bay PUD
Dare County
A Division of Energy, Mineral, and Land Resources file review has determined that Stormwater
Permit SW7040910 for a stormwater treatment system consisting of infiltration basins and wet
detention ponds serving Sunset Bay PUD expires on October 7, 2018. This is a reminder that
permit renewal applications are due 180 days prior to expiration. We do not have a record of
receiving a renewal application.
Please submit a completed permit renewal application along with a $505.00 fee for permit
renewal. Permit application forms for renewal can be found on our website at
https:/Ideg. nc.govlabout/divisions/energy-mineral-land-resources/energy-mineral-land-
ruleslstormwater-programlpost-construction. North Carolina General Statutes and the Coastal
Stormwater rules require that this property he covered under a stormwater permit. Failure to
maintain a permit subjects the owner to assessment of civil penalties.
If you have questions, please feel free to contact me at [phone]. I will be glad to discuss
this by phone or meet with you.

completed Name/Ownership Change Form within 30 days of procuring a developer, lessee or
purchaser for the property. I understand that failure to operate and maintain the stormwater
treatment facility in accordance with the permit is a violation of NC General Statue 143-215.1, and
may result in appropriate enforcement action including the assessment of civil penalties of up to
$25,000 per day, pursuant to NCGS 143-215.6.

Thank you for your response. I have met with the Developer to review your guidance on how to best move forward. l
will be coordinating with Mike Robinson, Glenda Wolfe, and the Developer to make sure we have all forms and
applications filled out and in your hands by the end of February. At that time, I will also present to you a clear schedule
for the physical maintenance in and around the basins and ponds.
Please call if you have any questions.
Thank you

Thank you for sending these forms.
have instructed Michel W Robinson PE,PLS to begin working on the Designer Certification Form.

I have a few questions before I can proceed with the possible transfer of the Stormwater Permit into the name of the
Bermuda Bay Homeowners Association. And of course, the signer of the Operation and Maintenance Agreements will
be subject to the answers to these questions.
One of the requirements of The Change of Ownership Form is that ownership of all the common areas has been
transferred to the HOA. This, in fact, has not occurred. Some of the common areas have been transferred, but some are
still retained in the name of Bermuda Bay, LLC. Transfer of ownership was always planned to be a staged process.
When the market stalled, so did development as well as the process of transfer of common areas.
If someone other than the property owner(s) will be applying for the permit, the property owners must either legally
transfer ownership to the Bermuda Bay I-IOA OR provide documentation of le fal agreement allowing the Bermuda I3ay
-IOA to accept the responsibility on behalf of the property owners for constructing and/or operating and maintaining, the
permitted stormwater management system.
The Maintenance Agreements state "The legally responsible party should not be a homeowners association unless more
than 50% of the lots have been sold and a resident of the subdivision has been named the president". Neither of these
have occurred.
This requirement will be waived for your situation. However, the person signing on behalf of the HOA must be
Pres/VP/or member -manager level.
I think we all are in agreement that the logical course of action is to have the permit ownership as well as the
maintenance agreements transferred into the name of the association, however due to the reasons outlined above, I do
not know if these transfers are possible. We may need to keep the permits in the name of Bermuda Bay, LLC and
change the Signing Official's name and address. I will await your feedback on this.
The 50% rule was set up to prevent the situation where only one or two homeowners are present in a 25 lot or greater
subdivision and are forced to be responsible for the entire development. Clearly, this is not the case at Bermuda Bay.
Please continue to fill out these forms and send to my attention. This does not create a conflict for DWQ
In the mean time, I have walked the site with the developer and discussed the physical maintenance issues involved with
the various basins and ponds. As soon as we get into some warmer, drier weather, we will begin. Our hope is to begin
the work in April and be completed by early summer,
I look forward to hearing from you. Please call with any questions. My cell phone number is 252-305-2400.

Permit Condition Violations
Stormwater Management Permit No. SW704091
Bermuda Bay, Dare County
Dear Ms Adams:
Thank you for taking the time to speak with me yesterday. As I mentioned in our conversation,
the notice of violation has just come to our attention. The addressee of your certified letter was
DS Russotto at 7578 Carotoke Highway in Jarvisburg, NC. This address is no longer associated
with Bermuda Bay nor is Mr. Russotto actively involved with Bermuda Bay.
The officers of the HOA Board are Leroy (Andy) Anderson, President, David Weybright,
See/Treas. and Glenda Wolfe is the onsite Manager. For all future communication please use the
Bermuda Bay HOA mailing address which is PO Box 7750, Kill Devil Hills, NC 27948 which is
also the mailing address for all of the above parties. The physical location is 1101 Cambridge
Rd., Kill Devil Hills, NC. You can also always email me or Glenda for faster communication:
�.wolfe r�,bermudabayhoa.or�, or dove bri Pub a minds. rin g.com
One item we would like to discuss with you is the possibility of transferring the Stormwater
Management Permit into the name of the Bermuda Bay HOA.
We were unaware of the fact you had no Designer's Certification on file. I have met with Mike
Robinson of Robinson Engineering and Surveying who was with Bissell and Associates in the
design and permitting phase of the Stormwater Management Plan. Mike will be working with us
to provide the Certification.
Addressing your concern about any parcels within Bermuda Bay having been transferred to
outside parties, we can assure you the various LLC's found in the tax records are all related
parties and there have been no transfers of any parcels to outside parties. The only transfers of
property that have occurred are the sale of individual condominium units within the community.
Perhaps having the permit transferred to the Bermuda Bay HOA would alleviate this concern.
We welcome your thoughts on this.

Amy, I look forward to your email with a proposed date or two that we can get together on site to
discuss the physical maintenance measures we need to take to return our Stormwater
Management System to optimal levels.
Sincerely,
David Weybright

4. Infiltration basin 96b does not appear to have been created. However, there is no impervious surface yet installed on this portion
of the development. Please remember the stormwater controls must be in place before the construction of any built -upon area
except roads.
5. Infiltration basin 46a and #5 are overgrown. The vegetation should be mowed/maintained at a height of approximately 6" and
any bare areas should be stabilized and seeded.

vegetation of the aquatic shelf along the perimeter of the pond.
9. Wet Detention pond 92 is overgrown and appears to have accumulated some sediment, Please evaluate how much sediment has
accumulated in this pond. In addition, algae covers a significant portion of the basin. This should be immediately addressed.
The outlet structure also appears to have developed a small erosional area and should be evaluated. The vegetation is also
overgrown and should be mowed/maintained at a height of approximately 6" and any bare areas should be stabilized and seeded.

separation to be reduced and may compromise the ability of the system to perform as designed. Reinoved
sediment shall be disposed of in an appropriate manner and shall riot be handled in a manner that will
adversely impact water quality (i.e. stockpiling near a stormwater treatment device or stream, etc.).
A benchmark shall be established in the pretreatment unit. The benchmark wi':1 document the original
design depth so that accurate sediment accumulation readings can be taken. The measuring device Lased to
determine the depth at the benchmark shall be such that it will give an accurate depth reading and not
readily penetrate into accumulated sediments.
When the design depth reads feet in the pretreatment unit; the sediment shall be
removed from both the pretreatment unit and the infiltration basin.
5. If the Division determines that the system is failing, the system will immediately be repaired to original
design specif"tcations. If the ystem cannot: be repaired to perform its design function, other stormwater
control devices as allowed by NCAC 2H A000 must be designed, approved and constructed.
I acknowledge and agree by my signature below that I am responsible for the performance of the five
maintenance procedures listed above. I agree to notify DWQ of any problems with the system or prior to any

documentation is attached. If the' applicant has designated an agent in the Stormwater Nlanagement Permit
Application Form, the agent may initial below. Attach justification if a requirement has not been (net.
Applicants Initials
DMR a. System is located 50 feet from class SA waters and 30 feet from other surface waters.
bMM b. System is located at least 100 feet from water supply wells.
DMlz c. Bottom ot'system is at least 2 feet above the seasonal high water table.
t)MVZ d. Bottom of the system is 3 feet above any bedrock. or impervious soil horizon.
�M2 e. System is not sited on or in fill material or DWQ approval has been obtained.

Drainage area for the device is less than 5 acres.
DM2 h.
Soils have a minimum hydraulic c6nductivity of 0.52 inches per hour and soils report is
attached.
�Mt2 i.
System captures and infiltrates the runoff from the first 1.0 inch of rainfall (1.5 inch event for
areas draining to SA waters ). Design volume and infiltration calculatio:s attache(;.
bme j_
System is sized to take into account the runoff at the ultimate built -out potential from all
surfaces draining to the system, including any off -site drainage. Calculations attached.
DMM k. All side slopes stabilized with vegetated cover are no steeper than 3:1 (1-r:V).
DMP_ ' 1. A pretreatment device such as a catch basin, grease trap, filter strip, grassed swale or
sediment trap is provided.
�lN2 m. Bottom of the device is covered with a layer of clean sand to an average depth of 4 inches or
pRavip�b dense vegetative cover is provided.

IV. INFILTRATION BASIN OPERATION AND MAINTENANCE AGREEMENT
1. After every runoff producing rainfall event and at.l.east monthly inspect the infiltration system for erosion,
trash accumulation, vegetative cover, and general condition.
2. Repair eroded areas immediately, re -seed as necessary to maintain adequate vegetative cover, mow
vegetated cover to maintain a maximum height of six inches, and remove trash as needed.
3. After every runoff producing rainfall event and at1,least monthly inspect the bypass, inflcw and overflow
structures for blockage and deterioration. Remove any blockage and repair thtt structure to approved design
specifications.
4. Remove accumulated sediment from the pretreatment system and infiltration basin annually or when depth
in the pretreatment unit is reduced to 75% of the original design depth. The systern shall be restored to the
original design depth without over -excavating. Over -excavating may cause the required water table
separation to be reduced and may compromise the ability of the system to perform as designed. Removed
sediment shall be disposed of in an appropriate manner and shall not be handled in a manner that will
adversely impact water quality (i.e. stockpiling near a stormwater treatment device or stream, etc.).
A benchmark shall be established in the pretreatment unit. The benchmark will document the original
design depth so that accurate sediment accumulation readings can be taken. The measuring device used to
determine the depth at the benchmark shall be such that it will give an accurate depth reading and not
readily penetrate into accumulated sediments.
When the design depth reads feet in the pretreatment unit, the sediment shall be
removed from both the pretreatment Unit and the infiltration basin.
S. If the Division determines that the system is failing, the system will immediately be repaired to original
design specifications. If the system cannot: be repaired to perform its design function, other stormwater
control devices as allowed by NCAC 2I-I.1000 must be designed, approved and constructed.
i acknowledge and agree by my signature below that I am responsible for the performance cf the five
maintenance procedures listed above. I agree; to notify DWQ of any problems with the system or prior to any
changes to the system or responsible party.

IV. INFILTRATION BASIN OPERATION AND MAINTENANCE AGREEMENT
1. After every runoff producing rainfall event and at.least monthly inspect the infiltration system for erosion,
trash accumulation, vegetative cover, and general condition.
2. Repair eroded areas immediately, re -seed as necessary to maintain acicquatc vegetative cover, mow
vegetated cover to maintain a maximum height of six inches, and remove trash as needed.
3. After every runoff producing rainfall event and tit',least monthly inspect the bypass, inflow and overflow
structures for blockage and deterioration. Remove any blockage anti repair thte structure: to approved design
specifications.
4. Remove accumulated sediment from the pretreatment system and infiltration basin annually or when depth
in the pretreatment unit is reduced to 75% of the original design depth. The system shall be restored to the
original design depth without over -excavating. Over -excavating may cause the requires, water table
separation to be reduced and may compromise the ability of the system to perform as designed. Removed
sediment shall be disposed of in an appropriate manner and shall not be handled in a manner that will
adversely impact water quality (i.e. stockpiling near a stormwater treatment crevice or stream, etc.).
A benchmark shall be established in the pretreatment unit. The benchmark will document the original
design depth so that accurate sediment accumulation readings can be taken. The meas�inng device used to
determine the depth at the benchmark shall be suAh that it will give an accurate depth reading and not
readily penetrate into accumulated sediments.
When the design depth reads (0'56 feet in the pretreatment unit, the sediment shall be
removed from both the pretreatment unit and" the infiltration basin.
5. If the Division determines that the system is failing, the system will immediately be repaired to original
design specifications. If the system cannot. be repaired to perform its design function, ol.her stormwater
control devices as allowed by NCAC 2H ACOO must be designed, approved and constructed. .
I acknowledge and agree by my signature below that I am responsible for the performance of the five
maintenance procedures listed above. I agree to notify DWQ of any problems with the system or prior to any
changes to the system or responsible party.

Footnotes:
t When using the Division 5A/DA tables, the correct SA/DA ratio for permanent pool sizing should be computed based upon the.
actual impervious % and permanent pool depth. Linear interpolation should be employed to determine the correct value for nom-
standard table entries.
2 In the 20 coastal counties, the requirement for a vegetative filter may be waived if the wet detention basin is designed to provide
90% TSS removal. The NCDENR BMP manual provides design tables for both 85% TSS removal and 90% TSS removal.

A formal overflow device has not been provided for in this basin
based upon the fact that the storage volume ratio provided is approximately 7 times
that of the required storage. Additionally, the basin is in close proximity to the adjoining
surface waters of Colington Creek that draw down will occur hydraulically through the
permeable soils into the wetlands that transistion into the adjoining surface waters
Basin 9A & 913 will be utilized as a combination vegetative filterlforebay device to accommodate
sediment collection. The volume of this measure has not. been included in the overall storage
calculations based upon its sole ability for sediment collection. (See volume calculations below)

Footnotes:
When using the Division SA/DA tables, the correct SrVDA ratio for permanent pool sizing should be computed based upon the
actual impervious % and permanent pool depth. Linear interpolation should be employed to determine the correct value for nam-
standard table entries.
2 In the 20 coastal counties, the requirement for a vegetative filter may be waived if the wet detention basin is designed to provide
90% TSS removal. The NCDENR BMP manual provides design tables for both 95% TSS removal and 90%TSS removal.
II. REQUIRED ITEMS CHECKLIST
The following checklist outlines design requirements per the Stormwater Best Management Practices Manual
(N.C. Department of Environment, Health and Natural Resources, February 1999) and Administrative Code
Section: 15 A NCAC 2H .100&.
Initial in the space provided to indicate the following design requirements have been met and suppoirting
documentation is attached. If the applicant has designated an agent in the Stormwater Management Permit
Application Form, the agent may initial below. If a requiirenaent has not been met, attach justirication.
Applicants Initials
E>mrZ a. The permanent pool depth is between 3 and 6 feet (required minimum of 3 feet).
WA b. The forebay volume is approximately equal to 20% of the basin volume.
DRAM c. The temporary pool controls runoff from the design storm event.
DARE d. The temporary pool draws down in 2 to 5 days.
AJ A e. If required, a 30-foot vegetative filter is provided at the outlet (include non -erosive flow
calculations)
bmm f. The basin length to width ratio is greater than 3:1.
bMfL g. The basin side slopes above the permanent pool are no steeper than 3:1.
AMR h. A submerged and vegetated perimeter shelf with a slope of 6:1 or less (show detail).
b#AV- i. Vegetative cover above the permanent pool elevation is specified.
NLA j. A trash rack or similar device is provided for both the overflow and orifice.
IUIL k. A recorded drainage easement is provided for each basin including access to nearest right-
of-way.
N/A 1. If the basin is used for sediment and erosion control during construction, clean out of tote
basin is specified prior to use as a wet detention basin.
/A na. A mechanism is specified which will drain the basin for maintenance or an e.trrtergency_.
III. WET DETENTION BASIN OPERATION AND MAINTENANCE AGREEMENT
The wet detention basin system is defined as the wet detention basin, pretreatment including forebcays and the
vegetated filter if one is provided.
This system (check one) fl does `d does not incorporate a vegetated linter at the outlet.
This system (check one) g does 0 does not incorporate pretreatment other than a forebay.
Form S W U- l02 Rev 3.99 Page 2 of d

Maintenance activities shall be performed as follows:
After every significant runoff producing rainfall event and at least monthly:
a. Inspect the wet detention basin system for sediment accumulation, erosion, trash accumulation,
vegetated cover, and general condition.
b. Check and clear the orifice of any obstructions such that drawdown of the temporary pool occurs within
2 to 5 days as designed.
2. Repair eroded areas immediately, re -seed as necessary to maintain good vegetative cover, mow vegetative
cover to maintain a maximum height of six inches, and remove trash as needed.
3. Inspect and repair the collection system (i.e_ catch basins, piping, swales, riprap, etc.) quarterly to maintain
proper functioning.
4. Remove accumulated sediment from the wet detention basin system semi-annually or when depth is
reduced to 75% of the original design -depth (see diagram below). Removed sediment shall be disposed of
in an' appropriate manner and shall be handled in a manner that will not adversely impact water quality (i.e.
stockpiling near a wet detention basin or stream, etc.).
The measuring device used to determine the sediment elevation shall be such that it will give an accurate
depth reading and not readily penetrate into accumulated sediments.

t When using the Division SA/DA tables, the correct SA/DA ratio ror permanent pool sizing should he computes[ based upon the
actual impervious %n and permanent pool depth. Linear interpolation should be employed to determine the correct value for nam-
standard table entries.
In the 20 coastal counties, the requirement for a vegetative filter may be waived it the wet detention basin is designed to provide
90% TSS removal. The NCDENR BMP manual provides design tables for both 85% TSS removal and 90% TSS removal.

Maintenance activities shall be performed as follows:
After every significant runoff producing rainfall event and at least monthly. -
a, Inspect the wet detention basin system for sediment accumulation, erosion, trash accumulation,
vegetated cover, and general condition.
b. Check and clear the orifice of any obstructions such that drawdown of the temporary pool occurs within
2 to 5 clays as designed.
2. Repair eroded areas immediately, re -seed as necessary to maintain good vegetative cover, now vegetative
cover to maintain a maximum height of six inches, and remove trash as needed.
3. Inspect and repair the collection system (i.e. catch basins, piping, swales, riprap, etc.) quarterly to maintain
proper functioning.
4. Remove accumulated sediment from the wet detention basin system semi-annually or when depth is
reduced to 75% of the original design depth (see diagram below). Removed sediment shall be disposed of
in an appropriate manner and shall be handled in a manner that will not adversely impact water duality (i.e.
stockpiling near a wet detention basin or stream, etc.).
The measuring device used to determine the sediment elevation shall be such that it will give an accurate
depth reading and not readily penetrate into accumulated sediments.
When the permanent pool depth reads -'0.1 ' feet in the main pond, the sediment shall be removed.
i
When the permanent pool depth reads P feet in the forebay, the sediment shall be removed.

IV. INFILTRATION BASIN OPERATION AND MAINTENANCE AGREEMENT
1. After every runoff producing rainfall event and at least monthly inspect the infiltration system for erosion,
trash accumulation, vegetative cover, and general condition.
2. Repair eroded areas immediately, re -seed as necessary to maintain adequate vegetative cover, mow
vegetated cover to maintain a maximum height of six inches, and remove trash as needed.
3. After every runoff producing rainfall event and at least monthly inspect the bypass, inflow and overflow
structures for blockage and deterioration. Remove any blockage and repair thstructure to approved design
specifications.
4.. Remove. accumuIate d sediment from the pretreatment system and infiltration basin annually or when depth
in.the pretreatment unit: is reduced to 75% of the original design deptl -.,The system shall be restored to the,
original design depth without over -excavating. Over -excavating may cause the required water table
separation to be reduced and may compromise the ability of the system to perform as designed. Removed
sediment shall be disposed of in an appropriate manner and shall not he handled in a manner that will
adversely impact water quality (i.e. stockpiling near a stormwater treatment Device or stream, etc.).
A'benchmark shall be established in the pretreatment unit. The benchmark will document the original
design depth so that accurate sediment accumulation readings can be'taken. The measuring device used to
determine the depth at the benchmark shall be such that it will give at,, accuntte depth reading and not
readily penetrate into accumulated sediments.
Wh.en the design depth reads ,50 feet in the pretreatment unit, the sediment shall be
removed from both the pretreatment unit and the infiltration basin.
5. If the Division determines that the system is failing, the system will it;smediately be repaired to original
design specifications. If the system cannot be repaired to perform its design function, otter stormwater
control devices as allowed by NCAC 2H .1000 must be designed, approved and constructed.
I acknowledge and agree by my signature below that I am responsible for the performance of the five
maintenance procedures listed above. I agree to notify DWQ of any problems with the syste;,A or prior to any
changes to the system or responsible party.
