EROSION CONTROL AND GRADING GENERAL NOTES:
1. THE CONTRACTOR SHALL CONTACT THE MISSOURI ONE CALL SYSTEM. CALL 8-1-1 OR (800) DIG-RITE (344-7483) FOR BURIED UTILITY LOCATION IDENTIFICATION
AND MARKING 72 HOURS BEFORE DOING ANY EXCAVATING ON SITE. CONTRACTOR IS TO COORDINATE UTILITY LOCATIONS WITH SECTION 017000 - EXECUTION
REQUIREMENTS.
2. CONTRACTOR SHALL EMPLOY EROSION CONTROL METHODS AS SHOWN ON PLANS AND AS RECOMMENDED BY THE MISSOURI DNR "FIELD GUIDE TO EROSION
CONTROL, SEDIMENT AND STORMWATER BEST MANAGEMENT PRACTICES FOR DEVELOPMENT SITES IN MISSOURI AND KANSAS".
3. ALL EROSION CONTROL MEASURES SHALL BE ADJUSTED TO MEET FIELD CONDITIONS AT THE TIME OF CONSTRUCTION AND SHALL BE INSTALLED PRIOR TO ANY
GRADING OR DISTURBANCE OF EXISTING SITE CONDITIONS.
4. SEDIMENT FENCE SHALL BE INSTALLED NO CLOSER THAN 10-FEET BEYOND THE TOE OF FILL SLOPES.
5. ALL EROSION CONTROL MEASURES SHALL BE CHECKED FOR STABILITY AND OPERATION AFTER A RAINFALL OF 0.5-INCHES OR MORE, BUT NOT LESS THAN ONCE
EVERY WEEK. ANY NEEDED REPAIRS SHALL BE MADE IMMEDIATELY. EROSION CONTROL MEASURES SHALL BE MAINTAINED ON A CONTINUAL BASIS UNTIL THE
SITE IS PERMANENTLY STABILIZED.
6. EROSION CONTROL MEASURES MUST BE RETURNED TO IN-PLACE CONDITIONS AT THE END OF EACH WORK DAY.
7. WHERE CONSTRUCTION ACTIVITIES HAVE PERMANENTLY CEASED OR HAVE BEEN TEMPORARILY SUSPENDED FOR MORE THAN FOURTEEN DAYS, OR WHEN FINAL
GRADES HAVE BEEN REACHED IN ANY PORTION OF THE SITE, STABILIZATION SHALL BE IMPLEMENTED WITHIN SEVEN DAYS.
8. ALL EXCESS SOIL MATERIALS SHALL BE STOCKPILED AT LOCATIONS APPROVED BY THE CONTRACTING OFFICER'S REPRESENTATIVE PRIOR TO PLACEMENT OF
ANY SOIL MATERIAL. STOCKPILES SHALL BE ENCLOSED WITH SEDIMENT FENCE UNTIL TEMPORARY OR PERMANENT VEGETATIVE COVER IS ESTABLISHED. ANY
STOCKPILE THAT REMAINS LONGER THAN SEVEN DAYS MUST BE STABILIZED BY SEEDING WITH ANNUAL RYE, WHEAT OR OATS AT A MINIMUM.
9. THE REMOVAL OF VEGETATIVE COVER AND EXPOSURE OF THE BARE GROUND MUST BE RESTRICTED TO THE MINIMUM AMOUNT NEEDED FOR CONSTRUCTION.
AREAS WHERE THE SOIL IS EXPOSED MUST BE PROTECTED FROM EROSION BY SEEDING AND MULCHING AS SOON AS POSSIBLE AFTER THE REMOVAL OF THE
ORIGINAL GROUND COVER.
10. EROSION MATS USED SHALL CONSIST ENTIRELY OF BIODEGRADABLE MATERIALS. NO SLOPES STEEPER THAN 4:1 ARE ANTICIPATED WITH THIS PROJECT. TYPE
2.B NETLESS ROLLED EROSION CONTROL BLANKETS SHALL BE USED ON-SITE TO REDUCE RISKS TO WILDLIFE.
11. AFTER THE SITE IS UNIFORMLY STABILIZED ACROSS 80% OF THE SITE AREA, AND AS APPROVED BY THE CONTRACT OFFICER'S REPRESENTATIVE, ALL
TEMPORARY EROSION CONTROL MEASURES MUST BE REMOVED AND DISPOSED OF PROPERLY. THE CONTRACTOR SHALL RESTORE ANY AREAS WHERE EROSION
CONTROL MEASURES HAVE BEEN REMOVED.

COURSES.

WASTEWATER SYSTEM GENERAL CONSTRUCTION NOTES:
1) WASTEWATER SYSTEM DESIGN IS BASED ON A 400 GALLONS PER DAY (GPD) FLOW FOR THE COMPLETED FACILITY AT FULL CAPACITY.
2) ALL NON-PRESSURIZED (GRAVITY) SEWER PIPE SHALL BE SCHEDULE 40 - 4" PVC UNLESS OTHERWISE NOTED.
3) ALL PRESSURIZED PIPING INSIDE THE LIFT STATION SHALL BE SCHEDULE 80 PVC UNLESS OTHERWISE NOTED.
4) ALL PRESSURIZED PIPING FROM THE LIFT STATION TO THE ABSORPTION FIELD MANIFOLD CONNECTION SHALL BE PE4710/SDR11 HIGH DENSITY
POLYETHYLENE (HDPE) UNLESS OTHERWISE NOTED.
5) ALL PRESSURIZED PIPING IN THE ABSORPTION TREATMENT FIELD SHALL BE SCHEDULE 40 PVC UNLESS OTHERWISE NOTED.
6) SYSTEM WILL NOT BE USED DURING FREEZING TEMPERATURES (SEASONAL SYSTEM). THEREFORE DRAIN BACK DURING SEASONAL OPERATION IS NOT
REQUIRED. DRAIN BACK VALVES MUST BE LEFT OPEN AT SYSTEM WINTER SHUT DOWN.
7) CONCRETE SEPTIC/PUMP TANK DIMENSIONS MAY VARY BUT RETAINED SEPTIC VOLUMES SHALL BE 1500 GALLONS TO THE SEPTIC TANK LIQUID LEVEL AND
800 GALLON MINIMUM FROM THE FLOAT OFF LEVEL TO THE INLET INVERT IN THE LIFT STATION TANK. ALL SEPTIC AND PUMP TANKS SHALL BE CONSTRUCTED IN
CONFORMANCE WITH THE STATE OF MISSOURI AND LOCAL/COUNTY REGULATIONS.
8) SEPTIC TANKS CANNOT BE CONSTRUCTED OF MORE THAN TWO SECTIONS. ALL TANK JOINTS/SEAMS, WHETHER MID TANK OR NEAR THE TOP, SHALL BE
WRAPPED WITH A 12" WIDE BUTYL RUBBER MEMBRANE TO PROVIDE A WATER TIGHT SEAL AND TO PHYSICALLY JOIN THE TWO SECTIONS TOGETHER. BUTYL
MATERIAL SHALL ALSO BE USED TO CONNECT THE TWO SECTIONS ON THE CONTACT SURFACE JOINTS OF THE TANK SECTIONS.
9) ALL PIPE PENETRATIONS INTO TANKS SHALL BE WATERTIGHT, FLEXIBLE GASKETED CONNECTIONS.
10) ALL SEPTIC TANK INLET AND OUTLET T'S SHALL BE A SANITARY OR "SWEEP" TEE.

ABSORPTION FIELD CONSTRUCTION NOTES:
ALL CONSTRUCTION SHALL BE IN ACCORDANCE WITH THE STATE OF MISSOURI LAWS
GOVERNING ONSITE WASTEWATER TREATMENT SYSTEMS AS APPLICABLE TO LOW
PRESSURE PIPE (LPP) SYSTEMS. THE CONTRACTOR MUST BE A CERTIFIED SEPTIC
INSTALLER IN THE STATE OF MISSOURI.
THE AREA OF THE WASTEWATER ABSORPTION FIELD CONTAINS TREES AND BRUSH.
VEGETATION LESS THAN 3" IN DIAMETER AS MEASURED 4' ABOVE THE GROUND SHALL BE
COMPLETELY REMOVED. LARGER TREES SHALL BE CUT FLUSH TO THE GROUND AND THE
STUMPS LEFT IN PLACE.
THE CONTRACTOR IS RESPONSIBLE FOR VERIFYING GROUND ELEVATIONS AND SLOPES
AND ABSORPTION SYSTEM LAYOUT ADJUSTMENTS PRIOR TO CLEARING TREES AND
VEGETATION. THE CONTRACTOR MUST CLEARLY MARK THE PROPOSED LOCATION OF THE
MANIFOLD PIPE, LATERAL TRENCHES AND CLEARING LIMITS WITH LATH AND/OR FLAGGING
AND PARTICIPATE IN A SITE MEETING WITH THE COR FOR A FIELD REVIEW PRIOR TO
PROCEEDING WITH ANY GROUND DISTURBING WORK.
ALL TRENCHES FOR THE DISTRIBUTION LATERALS SHALL BE INSTALLED LEVEL. THE DESIGN
ELEVATIONS ARE BASED ON SATELLITE IMAGERY CONTOURS THAT HAVE NOT BEEN FIELD
VERIFIED. THE CONTRACTOR MAY ADJUST THE ELEVATIONS AS NECESSARY TO MEET
EXISTING REAL GROUND ELEVATIONS AS LONG AS THE DESIGN PARAMETERS OF THE
MISSOURI LAWS AND THE DESIGN REQUIREMENTS ARE MET.
DUE TO NATURAL VARIATION IN SITE SLOPE AND LOCALIZED DEPRESSIONS IN THE GROUND,
IT MAY BE NECESSARY TO IMPORT FILL TO MEET THE MINIMUM 4" COVER REQUIREMENT
OVER THE TRENCH ROCK. BORROW FOR COVER SOIL MAY BE AVAILABLE FROM THE
GENERAL SITE GRADING OF THE HELIBASE SITE AT NO COST TO THE CONTRACTOR. COVER
SOIL SHALL BE CLASSIFIED AS LOAM TO MATCH THE EXISTING SITE TOPSOIL AND TO BE
SUITABLE AS A SEED BED FOR ESTABLISHMENT OF GRASS COVER.
INSTALL 4 ADDITIONAL 4"X4" MARKER POSTS
