working days or 90 calendar days, whichever is shorter.
MINIMUM EROSION CONTROL MEASURES
1, SUBMIT SEDIMENTATION AND EROSION CONTROL PLAN ALONG WITH FINANCIAL
RESPONSIBILITY FORM TO OBTAIN TOWN APPROVAL. APPROVAL REQUIRED BEFORE
PROCEEDING WITH LAND DISTURBING ACTIVITIES. REFERENCE TOWN CODE 153.071 FOR
ADDITIONAL INFORMATION.
2. INSTALL SILT FENCING IN LOCATIONS NOTED ON PLAN SHEET 2. USE METAL FENCE
POSTS AND TRENCH IN TOE OF FENCING IN 6" MINIMUM FOR MAXIMUM EFFICIENCY AND
DURABILITY.
3. PLACE CLEAN TYPE 1 SAND FILL TO ELEVATIONS NOTED ON STORMWATER AND GRADING
PLAN SHEET 2.
4. FILL SLOPES SHALL MAINTAIN 3:1 OR FLATTER.
5. INSTALL CONSTRUCTION ENTRANCE PAD AS DEPICTED ON STORMWATER PLAN, LOCATION
MAY BE ADJUSTED TO MEET BUILDERS NEEDS.
6. INSTALL FINAL STABILIZATION WITHIN 15 WORKING DAYS OF FINAL COMPLETION. FULL
STABILIZATION MUST BE ACCOMPLISHED WITH 90 DAYS OF PROJECT COMPLETION.
7. IF THE PROJECT IS DELAYED INSTALL TEMPORARY STABILIZATION WITHIN 15 WORKING
DAYS.
8, FINAL STABILIZATION SHALL BE BERMUDA SOD OR OUTER BANKS COMPATIBLE SEED
BLEND. IRRIGATE AS REQUIRED TO ESTABLISH A VIABLE STABILIZING CROP, SILT FENCING
SHALL REMAIN IN PLACE UNTIL FULL STABILIZATION IS ACHIEVED.
9. INSPECT ALL SEDIMENTATION AND EROSION CONTROL MEASURES DURING CONSTRUCTION
PARTICULARLY FOLLOWING SIGNIFICANT STORMWATER EVENTS. REPAIR ALL EROSION
GULLIES ALONG WITH SILT FENCING IMMEDIATELY.
10. ADDITIONAL MEASURES MAY BE REQUIRED IF EXCESSIVE STORMWATER RUNOFF OR
EROSION OCCURS PARTICULARLY THAT WHICH AFFECT ADJOINING PROPERTIES.

Relation of Water Mains to Sewers
( a ) Lateral Separation of Sewers and Water Mains. Water mains shall be laid at least 10 feet
laterally from existing or proposed sewers, unless local conditions or barriers prevent a 10-foot
lateral separation --in which case:
(1) The water main is laid in a separate trench, with the elevation of the bottom of the water
main at least 18 inches above the top of the sewer; or
(2) The water main is laid in the same trench as the sewer with the water main located at one
side on a bench of undisturbed earth, and with the elevation of the bottom of the water
main at least 18 inches above the top of the sewer.
( b ) Crossing a Water Main Over a Sewer. Whenever it is necessary for a water main to cross
over a sewer, the water main shall be laid at such an elevation that the bottom of the water main is
at least 18 inches above the top of the sewer, unless local conditions or barriers prevent an 18 inch
vertical separation --in which case both the water main and sewer shall be constructed of ferrous
materials and with joints that are equivalent to water main standards for a distance of 10 feet on
each side of the point of crossing.
( c ) Crossing a Water Main Under a Sewer. Whenever it is necessary for a water main to cross
under a sewer, both the water main and sewer shall be constructed of ferrous materials and with
joints equivalent to water main standards for a distance of 10 feet on each side of the point of
crossing. A section of water main pipe shall be centered at the point of crossing.

SYSTEM
ONNER NOTIFICATION REGARDING OPERATION AND MAINTENANCE REQUIREMENTS:
1. IN ACCORDANCE WITH 15A NCAC 18A.1961 THIS WASTEWATER SYSTEM HAS A TYPE IV
SYSTEM CLASSIFICATION WHICH REQUIRES A CONTRACT FOR OPERATIONS FROM A
PUBLIC MANAGEMENT ENTITY WITH A CERTIFIED OPERATOR OR A CONTRACT FOR
OPERATIONS WITH A PRIVATE CERTIFIED OPERATOR. THE OPERATOR SELECTED SHALL
BE IN GOOD STANDING WITH THE DARE COUNTY HEALTH DEPARTMENT.
2. THIS SYSTEM REQUIRES INSPECTIONS BY THE CONTRACT OPERATOR AT A MINIMUM OF
TWICE PER YEAR.
3, THIS SYSTEM REQUIRES REPORTING TO THE DARE COUNTY HEALTH DEPARTMENT ON A
YEARLY BASIS. ALL REPORTS SHALL BE SUBMITTED DIRECTLY BY THE OPERATOR TO
THE DARE COUNTY HEALTH DEPARTMENT WITH REPORT COPIES PROVIDED TO THE
PROPERTY OWNER.
4. THE REQUIRED INSPECTIONS SHALL AT A MINIMUM INCLUDE THE FOLLOWING:
A. OPERATOR SHALL MAINTAIN A WRITTEN LOG OF ALL INSPECTIONS
INCLUDING DATE AND TIME OF INSPECTION AND ALL SYSTEM FINDINGS.
THE LOG SHALL BE MADE AVAILABLE TO THE OWNER, DARE COUNTY
HEALTH DEPARTMENT AND ENGINEER UPON REQUEST.
B. TWICE YEARLY -VISUALLY INSPECT THE DRAINFIELD AREA TO CHECK FOR
EVIDENCE OF SURFACED WASTEWATER INCLUDING DEBRIS, PONDING OR
EXCESSIVELY GREEN VEGETATION AREAS. NOTIFY PROPERTY OWNER IF
VEGETATION AND LANDSCAPING HAS BEEN ALLOWED TO ENCROACH ONTO
THE DRAINFIELD.
C. TWICE YEARLY -MANUALLY OPERATE ALL FLOATS AND CONTROLS TO
ENSURE BOTH PUMPS ARE FUNCTIONING, DUPLEX ALTERNATING DOSING IS
OCCURRING AND ALARMS ARE FUNCTIONING AS DESIGNED,
D. YEARLY - MEASURE THE SLUDGE DEPTH IN THE SEPTIC TANK AND PUMP
TANK AND PUMP BOTH TANKS AS REQUIRED WHEN SLUDGE LEVELS
REACH Y3 LIQUID DEPTH IN THE SEPTIC TANK.
E. YEARLY - THE DRAINFIELD LATERALS SHALL BE FLUSHED UNTIL ALL
SLUDGE AND DEBRIS IS CLEAR. AFTER FLUSHING THE LATERALS, RESET
THE PRESSURE HEAD AT THE DRAINFIELD. MEASURE THE DRAW DOWN
RATES WITHIN THE PUMP TANK. THE DRAW DOWN RATES SHALL BE
COMPARED TO DESIGN RATES. SOME CREEP IN RATES IS EXPECTED AS
THE SYSTEM AGES BUT NOTIFY DARE COUNTY HEALTH DEPARTMENT,
OWNER AND ENGINEER IF RATES VARY SUDDENLY OR SIGNIFICANTLY.
