DESIGN DATA - ADMINISTRATION BUILDING

1. FLOW: TEN (10) WORKERS @ 25 GALLONS PER DAY (GPD) PER WORKER = 250

GALLONS PER DAY (GPD). FLOW IS BASED ON BUSINESSES/OFFICES/FACTORIES AT

15 GPD PER EMPLOYEE/SHIFT PLUS 10 GPD PER EMPLOYEE FOR SHOWERS.

2. SEPTIC TANK: SEPTIC TANK SIZE = 1.5 X PEAK FLOW = 1.5 X 250 GPD = 375 GPD.

USE 1 - 1,500 - GALLON SEPTIC TANK.

3. SUBSURFACE WASTEWATER INFILTRATION SYSTEM:

LONG TERM ACCEPTANCE RATE = 0.3 GPD PER SQUARE FOOT

250 GPD/0.3 GPD/SQUARE FOOT = 834 SQUARE FEET

FOR A THREE (3) FOOT WIDE TRENCH = 278 LINEAR FEET

INFILTRATOR QUICK FLOW CHAMBERS - 25% REDUCTION = 209 LINEAR FEET

USE A DISTRIBUTION BOX WITH 2- 108-FOOT LINES, 216 FEET TOTAL

2. SEPTIC TANK: SEPTIC TANK SIZE = 1.5 X PEAK FLOW = 1.5 X 845 GPD = 1,267.5 GPD.

USE 1 - 1,500 - GALLON SEPTIC TANK.

3. SUBSURFACE WASTEWATER INFILTRATION SYSTEM:

LONG TERM ACCEPTANCE RATE = 0.3 GPD PER SQUARE FOOT

845 GPD/0.3 GPD/SQUARE FOOT = 2,817 SQUARE FEET

FOR A THREE (3) FOOT WIDE TRENCH = 939 LINEAR FEET

INFILTRATOR QUICK FLOW CHAMBERS - 25% REDUCTION = 705 LINEAR FEET

EROSION CONTROL NOTES

1. EROSION CONTROL MEASURES SHALL BE INSTALLED PRIOR TO BEGINNING CLEARING

AND/OR GRADING OPERATIONS.

2. STABILIZATION MEASURES SHALL BE INITIATED AS SOON AS PRACTICABLE IN

PORTIONS OF THE SITE WHERE CONSTRUCTION ACTIVITIES HAVE TEMPORARILY OR

PERMANENTLY CEASED, BUT IN NO CASE MORE THAN FOURTEEN (14) DAYS AFTER WORK

HAS CEASED. WHERE CONSTRUCTION ACTIVITY ON A PORTION OF THE SITE IS

TEMPORARILY CEASED, AND EARTH-DISTURBING ACTIVITIES WILL BE RESUMED WITHIN

14 DAYS, TEMPORARY STABILIZATION MEASURES DO NOT HAVE TO BE INITIATED ON

THAT PORTION OF THE SITE.

3. ALL SEDIMENT AND EROSION CONTROL DEVICES SHALL BE INSPECTED ONCE EVERY

SEVEN (7) DAYS. IF SITE INSPECTIONS IDENTIFY BMPS THAT ARE DAMAGED OR ARE NOT

OPERATING EFFECTIVELY, MAINTENANCE MUST BE PERFORMED AS SOON AS PRACTICAL

OR AS REASONABLY POSSIBLE AND BEFORE THE NEXT STORM EVENT WHENEVER

PRACTICABLE.

4. PROVIDE SILT FENCE AND/OR OTHER CONTROL DEVICES, AS MAY BE REQUIRED, TO

CONTROL SOIL EROSION DURING UTILITY CONSTRUCTION. ALL DISTURBED AREAS SHALL

BE CLEANED, GRADED, AND STABILIZED WITH GRASSING IMMEDIATELY AFTER THE

UTILITY INSTALLATION.

5. ALL EROSION CONTROL DEVICES SHALL BE PROPERLY MAINTAINED DURING ALL

PHASES OF CONSTRUCTION UNTIL THE COMPLETION OF ALL CONSTRUCTION ACTIVITIES

AND ALL DISTURBED AREAS HAVE BEEN STABILIZED. REMOVE DEPOSITED SEDIMENT

COLLECTED BY SEDIMENT CONTROL MEASURE (SILT FENCE) WHEN THE DEPOSITED

SEDIMENT REACHES 1/3 THE HEIGHT OF THE ABOVE-GROUND PORTION OF THESE BMPS.

6. ADDITIONAL CONTROL DEVICES MAY BE REQUIRED DURING CONSTRUCTION IN ORDER

TO CONTROL EROSION AND/OR OFFSITE SEDIMENTATION. ALL TEMPORARY CONTROL

DEVICES SHALL BE REMOVED ONCE CONSTRUCTION IS COMPLETE AND THE SITE IS

STABILIZED.

7. THE CONTRACTOR MUST TAKE NECESSARY ACTION TO MINIMIZE THE TRACKING OF

MUD ONTO PAVED ROADWAY(S) FROM CONSTRUCTION AREAS AND THE GENERATION OF

DUST. THE CONTRACTOR SHALL DAILY REMOVE MUD/SOIL FROM PAVEMENT, AS MAY BE

REQUIRED.

8. LITTER, CONSTRUCTION DEBRIS, OILS, FUELS, AND BUILDING PRODUCTS WITH

SIGNIFICANT POTENTIAL FOR IMPACT AND CONSTRUCTION CHEMICALS THAT COULD BE

EXPOSED TO STORM WATER MUST BE PREVENTED FROM BECOMING A POLLUTANT

SOURCE IN STORM WATER DISCHARGES.

9. PREVENT THE DISCHARGE OF POLLUTANTS FROM SPILLS AND LEAKS AND IMPLEMENT

CHEMICAL SPILL AND LEAK PREVENTION AND RESPONSE PROCEDURES AS NEEDED.
