Everyone
As I read the DSO, {"The reservoir shall be maintained in a totally drained condition that prevents discharge of sediment
until repair, alteration, reconstruction or breaching is accomplished pursuant to plans and specifications developed by a
licensed engineer and approved by Danny Smith, Director, Division of Energy, Mineral, and Land Resources."] this plan
must be approved by Dam Safety prior to their work. Therefore, it is being forwarded to you all for review. Please let us
know who to send comments to - will it be Sue?
Also, recall the DSO includes the following:
The dam owners shall within 91 days of the issuance of this order, submit to this office plans, specifications, and
supporting data developed by a professional engineer for the necessary maintenance, repair, alteration, or
reconstruction to this dam or for the breach of this dam in such a manner that will preclude the washing of sediment
downstream.
And the 91 days (from January 24th) ended April 25th _
Thanks

Melissa,
Please find attached an interim plan to develop a dewatering pipe for the Lady Marion reservoir. The reservoir levels are
decreasing and we would like to implement the next stage of the dewatering plan. NCDEQ-Water Quality and ACOE
have been notified of the fill placement within the reservoir. Please note that the owner is planning to permanently
dewater the facility and restore the reservoir to a stream and overflow wetlands.
Thank you,
Chris

GENERAL SEEDING SPECIFICATIONS
DEFINITION
CONTROLLING RUNOFF AND EROSION ON DISTURBED AREAS BY ESTABLISHING PERENNIAL
VEGETATIVE COVER WITH SEED.
PURPOSE
TO REDUCE EROSION AND DECREASE SEDIMENT YIELD FROM DISTURBED AREAS, AND TO
PERMANENTLY STABILIZE SUCH AREAS IN A MANNER THAT IS ECONOMICAL, ADAPTS TO SITE
CONDITIONS, AND ALLOWS SELECTION OF THE MOST APPROPRIATE PLANT MATERIALS.
SPECIFICATIONS
SEEDBED REQUIREMENTS
ESTABLISHMENT OF VEGETATION SHOULD NOT BE ATTEMPTED ON SITES THAT ARE
UNSUITABLE DUE TO EXCESSIVE SOIL COMPACTION, INAPPROPRIATE SOIL TEXTURE, POOR
DRAINAGE, CONCENTRATED OVERLAND FLOW, OR STEEPNESS OF SLOPE UNTIL MEASURES
HAVE BEEN TAKEN TO CORRECT THESE PROBLEMS.
TO MAINTAIN A GOOD STAND OF VEGETATION, THE SOIL MUST MEET CERTAIN MINIMUM
REQUIREMENTS AS A GROWTH MEDIUM. THE EXISTING SOIL SHOULD HAVE THESE CRITERIA:
• ENOUGH FINE-GRAINED (SILT AND CLAY) MATERIAL TO MAINTAIN ADEQUATE MOISTURE
AND NUTRIENT SUPPLY (AVAILABLE WATER CAPACITY OF AT LEAST .05 INCHES WATER
TO 1 INCH OF SOIL).
■ SUFFICIENT PORE SPACE TO PERMIT ROOT PENETRATION.
• SUFFICIENT DEPTH OF SOIL TO PROVIDE AN ADEQUATE ROOT ZONE. THE DEPTH TO
ROCK OR IMPERMEABLE LAYERS SUCH AS HARDPANS SHOULD BE 12 INCHES OR MORE,
EXCEPT ON SLOPES STEEPER THAN 2.1 WHERE THE ADDITION OF SOIL IS NOT FEASIBLE.
■ A FAVORABLE PH RANGE FOR PLANT GROWTH, USUALLY 6.0 - 6.5.
• FREE FROM LARGE ROOTS, BRANCHES, STONES, LARGE CLODS OF EARTH, OR TRASH OF
ANY KIND. CLODS AND STONES MAY BE LEFT ON SLOPES STEEPER THAN 3:1 IF THEY
ARE TO BE HYDRO SEEDED.
IF ANY OF THE ABOVE CRITERIA ARE NOT MET - I.E., IF EXISTING SOIL IS TOO COARSE, DENSE,
SHALLOW OR ACIDIC TO FOSTER VEGETATION - SPECIAL AMENDMENTS ARE REQUIRED. THE
SOIL CONDITIONERS DESCRIBED BELOW MAY BE BENEFICIAL OR, PREFERABLY, TOPSOIL MAY
BE APPLIED.
SEEDBED PREPARATION
INSTALL NECESSARY MECHANICAL EROSION AND SEDIMENTATION CONTROL PRACTICES
BEFORE SEEDING, AND COMPLETE GRADING ACCORDING TO THE APPROVED PLAN.
LIME AND FERTILIZER NEEDS SHOULD BE DETERMINED BY SOIL TESTS. DIRECTIONS, SAMPLE
CARTONS, AND INFORMATION SHEETS ARE AVAILABLE THROUGH COUNTY AGRICULTURAL
EXTENSION OFFICES. TESTING IS ALSO DONE BY COMMERCIAL LABORATORIES.
WHEN SOIL TESTS RESULTS ARE NOT AVAILABLE, FOLLOW RATES SUGGESTED IN THE
SEEDING SPECIFICATIONS SHOWN BELOW. APPLICATION RATES USUALLY FALL INTO THE
FOLLOWING RANGES:
• GROUND AGRICULTURAL LIMESTONE:
LIGHT -TEXTURED, SANDY SOILS: 1 TO 1-112 TONSIACRE
HEAVY -TEXTURED. CLAYEY SOILS: 2-3 TONS/ACRE
■ FERTILIZER:
GRASSES: 800-1200 LB/ACRE OF 10-10-10 (OR THE EQUIVALENT)
GRASS -LEGUME MIXTURES: 800-1200 LB/ACRE OF 5-10-10 (OR THE EQUIVALENT)
APPLY LIME AND FERTILIZER EVENLY AND INCORPORATE INTO THE TOP 4-6 INCHES OF SOIL
BY DISKING OR OTHER SUITABLE MEANS. OPERATE MACHINERY ON THE CONTOUR. WHEN
USING A HYDRO SEEDER, APPLY LIME AND FERTILIZER TO A ROUGH, LOOSE SURFACE.
:1f111e3:I:1ii6ill;;UUT41:92uVisl i[6)6y:1 =19]LLei
COMPLETE SEEDBED PREPARATION BY BREAKING UP LARGE CLODS AND RAKING INTO A
SMOOTH, UNIFORM SURFACE (SLOPES LESS THAN 3:1). FILL IN OR LEVEL DEPRESSIONS
THAT CAN COLLECT WATER. BROADCAST SEED INTO A FRESHLY LOOSENED SEEDBED THAT
HAS NOT BEEN SEALED BY RAINFALL.
SEEDING
SEEDING DATES GIVEN IN THE SEEDING MIXTURE SPECIFICATIONS ARE DESIGNATED AS
"BEST" OR "POSSIBLE". SEEDINGS PROPERLY CARRIED OUT WITHIN THE "BEST" DATES HAVE
A HIGH PROBABILITY OF SUCCESS. IT IS ALSO POSSIBLE TO HAVE SATISFACTORY
ESTABLISHMENT WHEN SEEDING OUTSIDE THESE DATES. HOWEVER, AS YOU DEVIATE FROM
THEM, THE PROBABILITY OF FAILURE INCREASES RAPIDLY. SEEDING ON THE LAST DATE
SHOWN UNDER "POSSIBLE" MAY REDUCE CHANGES OF SUCCESS BY 30-50%. ALWAYS TAKE
THIS INTO ACCOUNT IN SCHEDULING LAND -DISTURBING ACTIVITIES.
USE CERTIFIED SEED FOR PERMANENT SEEDING WHENEVER POSSIBLE.
LABELING OF NON -CERTIFIED SEED IS ALSO REQUIRED BY LAW. LABELS CONTAIN
IMPORTANT INFORMATION ON SEED PURITY, GERMINATION, AND PRESENCE OF WOOD
SEEDS. SEEDS MUST MEET STATE STANDARDS FOR CONTENT OF NOXIOUS WEEDS. DO NO
ACCEPT SEED CONTAINING "PROHIBITED" NOXIOUS WEED SEED.
INOCULATE LEGUME SEED WITH THE RHIZOBIUM BACTERIA APPROPRIATE TO THE SPECIES
OF LEGUME.
APPLY SEED UNIFORMLY WITH A CYCLONE SEEDER, DROP -TYPE SPREADER, DRILL,
CULTIPACKER SEEDER, OR HYDRO SEEDER ON A FIRM, FRIABLE SEEDBED.
WHEN USING A DRILL OR CULTIPACKER SEEDER, PLANT SMALL GRAINS NO MORE THAN 1
INCH DEEP, GRASSES AND LEGUMES NO MORE THAN 112 INCH. EQUIPMENT SHOULD BE
CALIBRATED IN THE FIELD FOR THE DESIRED SEEDING RATE.
WHEN USING BROADCAST -SEEDING METHODS, SUBDIVIDE THE AREA INTO WORKABLE
SECTIONS AND DETERMINE THE AMOUNT OF SEED NEEDED FOR EACH SECTION. APPLY
ONE-HALF THE SEED WHILE MOVING BACK AND FORTH ACROSS THE AREA, MAKING A
UNIFORM PATTERN: THEN APPLY THE SECOND HALF IN THE SAME WAY, BUT MOVING AT
RIGHT ANGLES TO THE FIRST PASS.
MULCH ALL PLANTINGS IMMEDIATELY AFTER SEEDING.
HYDRO SEEDING
SURFACE ROUGHENING IS PARTICULARLY IMPORTANT WHEN HYDRO SEEDING, AS A
ROUGHENED SLOPE WILL PROVIDE SOME NATURAL COVERAGE FOR LIME, FERTILIZER, AND
SEED. THE SURFACE SHOULD NOT BE COMPACTED OR SMOOTH. FINE SEEDBED
PREPARATION IS NOT NECESSARY FOR HYDRO SEEDING OPERATIONS: LARGE CLODS,
STONES, AND IRREGULARITIES PROVIDE CAVITIES IN WHICH SEEDS CAN LODGE.
RATE OF WOOD FIBER (CELLULOSE) APPLICATION SHOULD BE AT LEAST 4,000 LBIACRE.
APPLY LEGUME INOCULANTS AT FOUR TIMES THE RECOMMENDED RATE WHEN ADDING
INOCULANT TO A HYDRO SEEDER SLURRY.
IF A MACHINERY BREAKDOWN OF 112 TO 2 HOURS OCCURS, ADD 50% MORE SEED TO THE
TANK, BASED ON THE PROPORTION OF THE SLURRY REMAINING. THIS SHOULD COMPENSATE
FOR DAMAGE TO SEED. BEYOND 2 HOURS, A FULL RATE OF NEW SEED MAY BE NECESSARY.
LIME IS NOT NORMALLY APPLIED WITH A HYDRAULIC SEEDER BECAUSE IT IS ABRASIVE. IT
CAN BE BLOWN ONTO STEEP SLOPES IN DRY FORM.
IF, Fill I'Llri:RlFill r.l:�
GENERALLY, A STAND OF VEGETATION CANNOT BE DETERMINED TO BE FULLY ESTABLISHED
UNTIL SOIL COVER HAS BEEN MAINTAINED FOR ONE FULL YEAR FROM PLANTING. INSPECT
SEEDED AREAS FOR FAILURE AND MAKE NECESSARY REPAIRS AND RESEEDINGS WITHIN THE
SAME SEASON, IF POSSIBLE.
RESEEDING --IF A STAND HAS INADEQUATE COVER, RE-EVALUATE CHOICE OF PLANT
MATERIALS AND QUANTITIES OF LIME AND FERTILIZER. RE-ESTABLISH THE STAND AFTER
SEEDBED PREPARATION OR OVER- SEED THE STAND. CONSIDER SEEDING TEMPORARY,
ANNUAL SPECIES IF THE TIME OF YEAR IS NOT APPROPRIATE FOR PERMANENT SEEDING.
IF VEGETATION FAILS TO GROW, SOIL MUST BE TESTED TO DETERMINE IF ACIDITY OR
NUTRIENT IMBALANCE IS RESPONSIBLE.
FERTILIZATION --ON THE TYPICAL DISTURBED SITE, FULL ESTABLISHMENT USUALLY
REQUIRES RE -FERTILIZATION IN THE SECOND GROWING SEASON. FINE TURF REQUIRES
ANNUAL MAINTENANCE FERTILIZATION. USE SOIL TESTS IF POSSIBLE OR FOLLOW THE
GUIDELINES GIVEN FOR THE SPECIFIC SEEDING MIXTURE.
