REQUEST FOR ADDITIONAL INFORMATION
Stormwater Project No. SW8 970531 Modification
Carrera
Brunswick County
Dear Mr. Anderson:
The Wilmington Regional Office received a Stormwater Management Permit Application for Carrera
on December 15, 1999. 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. Please provide a more detailed vicinity map, in accordance with the rules. Please label Industrial
Boulevard, major roads such as 17/74, and highlight the site.
2. Please delineate the 0.5 acres of future impervious, if known. If not known, a modification to
add this to the site plan must be permitted prior to construction, and may not be approved. The
new site's density is already at 34%, but taking all of the site area into account, the project
meets low density. Please be aware that the location and grading of the future impervious will
be the determining factors as to whether or not the future area is approved.
3. Please show some additional spot elevations in the south parking lot. It appears that the 39
contour runs along the edge of the sidewalk, but it is not picked up on the west side. Please
continue the proposed 39 contour.
4. According to the rules, the application must be signed by the president or vice-president of the
entire company. As a general manager, you do not qualify to sign the application. Please either
have the application signed by the appropriate person, or provide a signed letter of authorization
from the president or vice president, authorizing you to sign on the company's behalf.
5. Please provide the mailing address of the company's headquarters, not the local office. The local
office address is listed in Section I, Part 5 of the application. Of course, if the two are the same,
then you show the same address in both places.

NARRATIVE
^ESCRIPTION
The site is a 11.13 acre tract located in the Leland Industrial Park consisting of
moderately wooded, sandy clay topsoil and grades ranging from 0.5% to 2.0%.
Approximately 5 acres will be graded to allow construction of a new manufacturing
facility with paved parking and paved access. 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.
EROSION CONTROL MEASURES
The attached plans and specifications give the requirements for erosion control
measures. A temporary silt trap will be installed at the outfall from the property. A gravel
construction entrance will be constructed at the entrance. Rip rap energy dissipators will
be provided at outlets with velocities exceeding 2.0 feet per second. Maintenance will be
provided by the grading contractor and developer.
CONSTRUCTION SEQUENCE
The Contractor will install the gravel construction entrance and silt trap prior to
beginning any clearing and grading operations. Silt fence will be installed when and if
conditions warrant during construction. Disturbed areas will be landscaped or seeded upon
completion.
STORMWATER MEASURES
The project is a low -density project as less than 30% of the land area will be covered
by impervious surfaces. Runoff will sheet flow to grassed swales before leaving the site.

MAINTENANCE PLAN
A. All ero5i-- aria sediment controi practices will be checked for stability and operation
following every runoff -producing rainfall but in no case less than once every week. Any
needed repairs will be made immediately to maintain all practices as designed.
2. The sediment basin will be cleaned out when the level of sediment reaches 2.0 ft below
the top of the riser. Gravel will be cleaned or replaced when the sediment pool no longer
drains properly.
3. Sediment will be removed from the sediment trap and block and gravel inlet protection
device when storage capacity has been approximately 50% filled. Gravel will be cleaned or
replaced when the sediment pool no longer drains properly.
4. Sediment will be removed from behind the sediment fence when it becomes about 0.5 ft
deep at the fence. The sediment fence will be repaired as necessary to maintain a barrier.
5. Check ditches, swales, pond banks, and other seeded areas for erosion and
sedimentation after runoff -producing rains. 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. Sediment producing areas should be treated
immediately.
6. Inspect gravel construction roads, entrances, and parking areas periodically for
sediment build-up on surface. Topdress with new gravel as needed.

SECTION 02920
SOIL EROSION AND SEDIMENTATION CONTROL
i. GENERAL

the erosion of soil and the sedimentation of streams, lakes, reservoirs, other water
impoundments, ground surfaces, or other property as required by State and Local
regulations.
1.2 The Contractor shall install all required silt fences, sediment basins, check dams, and
construction entrances at the initiation of work, and have these measures reviewed and
approved by the local permit authority prior to clearing and grading operations.
1.3 The Contractor shall, within 15 working days or 30 calendar days of suspension or
completion of land disturbing activities, provide permanent protective covering for disturbed
areas. Temporary and permanent erosion control measures shall be coordinated to assure
economical, effective, and continuous erosion and siltation control throughout the
construction and post -construction period. Use the specified seed for both temporary and
permanent seeding.
2. PRODUCTS
2.1 Asphalt for anchoring mulch shall be Type SS-1 Emulsion.
2.2 Fertilizer shall be 10-10-10 grade or equivalent.
2.3 Lime shall be dolomitic agricultural ground limestone containing not less than 10
percent magnesium oxide.
2.4 Mulch shall be small grain straw, hay, wood chips, asphalt emulsion, jute or other
suitable material free of undesirable weed seed.
2.5 Phosphate shall be 20 percent superphosphate or equivalent.
2.6 Seed for temporary and permanent applications shall
Bermuda, 20% turf Fescue, 10% Creeping Red Fescue,
Bermuda seed shall be hulled for wane weather planting a
planting. Purity of seed shall be a minimum of 98 percent
minimum of 85 percent

2.7 Silt fence shall consist of NCDOT Class A fabric supported by wood or metal posts
spaced not more than 6 feet on center. The bottom of the fabric shall be buried a minimum
of 6 inches.
2.8 Gravel for check dams shall be #57 washed stone.
2.9 Aggregate for construction entrance shall be #4 washed stone.
2.10 Stone rip rap for check dams and erosion control shall be NCDOT Class A or B as
shown.
3. EXECUTION
3.1 General: Take every practicable measure during construction or suspension to work to
minimize erosion and siltation. Measures should include good construction practices,
temporary physical barriers to sediment travel, settling basins for new ditches, and
establishment of vegetative cover.
3.2 Construction Practices
3.2.1 Avoid dumping soil or sediment into any wetland or watercourse.
3.2.2 Maintain an undisturbed vegetative buffer where possible between a natural
watercourse and trenching and grading operations.
3.2.3 Avoid equipment crossings of streams, creeks, and ditches where practicable.
3.2.4 Grade all cut, fill and ditch slopes to minimum slope of 3:1, unless otherwise shown
or directed.
3.3 Temporary Physical Barriers are required where sedimentation on off site property or
excessive erosion is a problem.
3.3. i Mulch shall be used for temporary stabilization of areas subject to excessive erosion
and for protection of seed beds after planting where required.
1. Apply grain straw and hay at a rate of 75 to 100 pounds per 1000 square feet and
wood chips at a rate of 500 pounds per 1000 square feet. Jute and mesh should be
installed as per manufacturer's instructions.
W

2. Asphalt emulsion for slope stabilization should be applied at a rate of 1000
gallons per acre. Asphalt emulsion used for anchoring straw should be applied at a
rate of 150 gallons per ton of straw.
3.3.2 Silt Fences shall be used at the base of slopes to restrict movement of sediment from
the site.
3.3.3 Stone Check Dams, placed at the discharges of creeks, ditches, and swales, shall
consist of Class A rip rap at minimum two feet high and three feet thick across the
watercourse, with a one foot thick layer of gravel on upstream side.
3.4 Vegetative Cover. Establish permanent vegetative cover on all unpaved areas
disturbed by the work.
3.4.1 .Preparation of Seedbed: Areas to be seeded shall be scared to a depth of 4 inches
and until a firm, well pulverized, uniform seedbed is prepared. Lime, phosphorous and
fertilizer shall be applied during the scarification process in accordance with the following
rates:
Lime: 45 pounds per 1000 square feet
Phosphorous: 20 pounds per 1000 square feet
Fertilizer: 17 pounds per 1000 square feet
3.4.2 Seeding: Disturbed areas shall be seeded with 2 to 3 pounds per 1000 square feet of
the specified seed mixture. Seed shall be worked into the bed to a depth of 1/4 inch.
3.4.3 Mulch all areas immediately after seeding. Mulch shall be applied and anchored as
specified hereinbefore.
3.5 Construction Entrance: Provide an aggregate drive, 25 feet wide by 50 feet long by 6
inches thick at each entrance to the site used by construction vehicles, until such time as
the permanent roadway is constructed.
3.6 Maintenance: The Owner and Contractor shall be responsible for maintaining all
temporary and permanent erosion control measures. Temporary structures shall be
maintained until such time as vegetation is firmly established in the area protected by the
structure. Permanent streambank protection and grassed areas shall be maintained until
completion of the project. Areas that fail to show a suitable stand of grass or which are
damaged by erosion shall be immediately repaired.
