APPLICABLE STATE AND/OR LOCAL WASTE DISPOSAL, SANITARY SEWER OR

SEPTIC SYSTEM REGULATIONS AND PROVIDE FOR THE PROPER DISPOSAL

OF CONTAMINATED SOILS TO THE EXTENT THESE ARE LOCATED WITHIN

THE PERMITTED AREA.

2. HANDLING CONSTRUCTION CHEMICALS. PERFORM MIXING, PUMPING,

TRANSFERRING OR OTHER HANDLING OF CONSTRUCTION CHEMICALS

SUCH AS FERTILIZER, LIME, ASPHALT, CONCRETE DRYING COMPOUNDS,

AND ALL OTHER POTENTIALLY HAZARDOUS MATERIALS IN AN AREA AWAY

FROM ANY WATERCOURSE, DITCH OR STORM DRAIN.

3. THE FOLLOWING GOOD HOUSEKEEPING PRACTICES WILL BE FOLLOWED ON

SITE DURING THE CONSTRUCTION PROJECT:

A. AN EFFORT WILL BE MADE TO STORE ONLY ENOUGH PRODUCT REQUIRED

TO DO THE JOB.

B. ALL MATERIALS STORED ON SITE WILL BE STORED IN A NEAT, ORDERLY

MANNER IN THEIR APPROPRIATE CONTAINERS AND, IF POSSIBLE, UNDER

A ROOF OR OTHER ENCLOSURE.

C. PRODUCTS WILL BE KEPT IN THEIR ORIGINAL CONTAINERS WITH THE

MANUFACTURER'S LABEL. SUBSTANCES WILL NOT BE MIXED WITH ONE

ANOTHER UNLESS RECOMMENDED BY THE MANUFACTURER.

D. WHENEVER POSSIBLE, ALL OF A PRODUCT WILL BE USED UP BEFORE

DISPOSING OF THE CONTAINER.

E. THE MANUFACTURER'S RECOMMENDATIONS FOR PROPER USE AND

DISPOSAL WILL BE FOLLOWED.

4. AT NO TIME WILL CONSTRUCTION VEHICLES BE ALLOWED TO ENTER AREAS

OUTSIDE THE LIMIT OF DISTURBANCE BOUNDARIES SHOWN ON THE PLAN

MAPS. THESE AREAS MUST BE CLEARLY MARKED AND FENCED OFF

BEFORE CLEARING AND GRUBBING OPERATIONS BEGIN.

5. PROPERLY MAINTAIN ALL EROSION AND SEDIMENT BMPS UNTIL THE SITE IS

PERMANENTLY STABILIZED. MAINTENANCE MUST INCLUDE INSPECTIONS

WEEKLY BASIS. ALL PREVENTATIVE AND REMEDIAL MAINTENANCE WORK,

INCLUDING CLEANOUT, REPAIR, RE-PLACEMENT, RE-GRADING,

RE-SEEDING, RE-MULCHING, AND RE-NETTING MUST BE PERFORMED

IMMEDIATELY. IF THE E&S BMPS FAIL TO PERFORM AS EXPECTED,

REPLACEMENT BMPS, OR MODIFICATION OF THOSE INSTALLED WILL BE

REQUIRED.

6. IMMEDIATELY UPON DISCOVERING UNFORESEEN CIRCUMSTANCES POSING

THE POTENTIAL FOR ACCELERATED EROSION AND/OR SEDIMENT

POLLUTION, IMPLEMENT APPROPRIATE BEST MANAGEMENT PRACTICES TO

ELIMINATE THE POTENTIAL FOR ACCELERATED EROSION AND/OR

SEDIMENT POLLUTION.

7. KEEP A SUPPLY OF EROSION CONTROL MATERIAL (SILT FENCE, JUTE MESH,

RIP RAP, ETC.) ON-SITE FOR MAINTENANCE AND EMERGENCY REPAIRS.

8. OBTAIN ALL REGULATORY AGENCY PERMITS REQUIRED FOR THE SITE

LOCATIONS.

10. PERMANENTLY STABILIZE BY SEEDING PER PLANS. SPOILS TO BE PLACED

AROUND EXISTING STRUCTURES AND EQUIPMENT.

11. ANY OFF-SITE BORROW AND WASTE REQUIRED FOR THIS PROJECT MUST

COME FROM A SITE WITH AN APPROVED EROSION CONTROL PLAN, A SITE

DEMOLITION ACTIVITIES OR GENERATED BY ANY ACTIVITIES ON SITE MUST

BE DISPOSED OF AT A FACILITY REGULATED BY THE DIVISION OF SOLID

WASTE MANAGEMENT OR PER DIVISION OF SOLID WASTE MANAGEMENT

OR DIVISION OF WATER RESOURCES RULES AND REGULATIONS.

12. ADDITIONAL MEASURES MAY BE REQUIRED. THE CONTRACTOR IS

RESPONSIBLE FOR THE CONTROL OF SEDIMENT ON-SITE. IF THE

APPROVED EROSION AND SEDIMENTATION CONTROL MEASURES PROVE

INSUFFICIENT, THE CONTRACTOR MUST TAKE THOSE ADDITIONAL STEPS

NECESSARY TO STOP SEDIMENT FROM LEAVING THIS SITE.

13. PROVIDE EROSION AND SEDIMENT CONTROL FOR UTILITY CONSTRUCTION

IN ACCORDANCE WITH APPROVED PLANS. UTILITY CONSTRUCTION MUST

NOTES:

WHERE VEGETATIVE STABILIZATION TECHNIQUES MAY CAUSE STRUCTURAL INSTABILITY OR ARE OTHERWISE UNOBTAINABLE, ALTERNATIVE STABILIZATION TECHNIQUES MUST BE EMPLOYED. THESE TECHNIQUES MAY INCLUDE MULCHING OR EROSION MATTING.OR NO MORE THAN 90 CALENDAR DAYS

(WHICHEVER IS SHORTER).

1. INSTALL EROSION AND SEDIMENT CONTROL (E&SC) DEVICES IN

ACCORDANCE WITH THE PLAN DRAWINGS.

2. THE NPDES CONSTRUCTION PERMIT REQUIRES EROSION CONTROL

INSPECTIONS AND MAINTAIN RECORDS UNTIL THE AREA HAS STABILIZED

EVIDENT BY 95% VEGETATIVE GROWTH FOR AREAS PROVIDED SEEDING.

TO FACILITATE RAINFALL MONITORING, A RAIN GAUGE IS REQUIRED TO

BE ON SITE. ADDITIONALLY THE CONTRACTOR IS RESPONSIBLE FOR

CONDUCTING "SELF-INSPECTIONS INDICATING THE DATE BMPS ARE

INSTALLED AND STABILIZATION MEASURES (SEEDING/MULCHING/ OR

SOD) ARE INITIATED. BOTH INSPECTIONS ARE RECORDED ON THE SAME

REPORT FORM AND MUST BE MAINTAINED BY THE CONTRACTOR AT THE

ONSITE OFFICE. ONCE STABILIZATION HAS BEEN ACCOMPLISHED

INSPECTION RECORDS ARE TO BE FORWARDED TO EAD AND ALL

TEMPORARY EROSION/SEDIMENTATION CONTROL DEVICES REMOVED.

7. REMOVE SEDIMENT AND RESTORE SEDIMENT TRAPS TO ORIGINAL

DIMENSIONS WHEN THE SEDIMENT HAS ACCUMULATED TO ONE-HALF

THE DESIGN DEPTH OF THE TRAP. PLACE SEDIMENT IN DESIGNATED

DISPOSAL AREA, AND REPLACE GRAVEL FACING THAT IS IMPAIRED BY

SEDIMENT. CHECK THE STRUCTURE FOR DAMAGE FROM EROSION OR

PIPING. ENSURE SPILLWAY REMAINS A MINIMUM OF 1.5 FEET BELOW THE
