2. CONSTRUCT CHANNEL AT A MINIMUM GRADE OF 0.5%.

3. DO NOT CONSTRUCT WITH LONGITUDINAL JOINTS IF USING A PLASTIC LINER OR IMPERMEABLE GEOTEXTILE

MEMBRANE. BURY THE UPSTREAM EDGE OF THE LINER A MINIMUM OF 6' DEEP AND SECURE WITH RIPRAP

OR SANDBAGS.

4. ALL PUMPS WILL HAVE A SCREENED FOOT VALVE IN ACCORDANCE WITH CONTRACT REQUIREMENTS.

5. TREAT ALL TURBID WATER FROM SUMP PUMP OPERATIONS BEFORE IT RE-ENTERS THE STREAM BY USE OF

FILTERS EITHER VEGETATION OR MANMADE, SETTLING PONDS, FLOCCULENT SOCKS ETC.

6. THE CONTRACTOR SHALL SUBMIT A WRITTEN DEWATERING PLAN TO THE CO FOR APPROVAL 30 DAYS IN

ADVANCE OF CONSTRUCTION.

7. ALL REPLACEMENT SITES REQUIRE DEWATERING FACILITIES AND A SUMP PUMP TO BYPASS WATER AND

REMOVE WATER FROM WITHIN THE WORK SITE. THE DESIGN OF THE DEWATERING OPERATIONS MUST

ALLOW 1 TRAVEL LAND BYPASS ACROSS THE SITE FOR PUBLIC ACCESS VEHICLES.

8. THE CONTRACTOR SHOULD EXPECT AND PREPARE FOR A WIDE RANGE OF FLOW CONDITIONS AT SE

ALASKA WORK SITES.

9. TEMPORARY CULVERT CAN BE USED IN PLACE OF PLASTIC LINED OR RIPRAP LINED DIVERSION CHANNELS.

ALL TEMPORARY CULVERT DIVERSIONS MUST BE APPROVED BY THE CO 30 DAYS PRIOR TO

CONSTRUCTION.

2. THE CO MAY REQUIRE ADJUSTMENTS TO ACTUAL LENGTHS OR

LOCATIONS TO FIT FIELD CONDITIONS.

3. INSPECT SILT FENCES AFTER EACH RUNOFF EVENT AND

IMMEDIATELY REPAIR ALL EROSION ALONG EDGES AND BOTTOM.

4. ACCUMULATED DEPTH OF SEDIMENT SHALL NOT EXCEED ONE

HALF OF THE ORIGINAL HEIGHT OF THE SILT FENCE.

5. IN AREAS DESIGNATED FOR BRUSH BARRIERS, LIMIT CLEARING

TO TREES, SHRUBS AND PLANTS LESS THAN 4" IN DIAMETER.

GRUBBING SHALL NOT BE PERFORMED IN THOSE AREAS.

6. BRUSH BARRIER SHALL BE CONSTRUCTED APPROXIMATELY

PARALLEL TO ORIGINAL GROUND CONTOUR. USE

WELL-INTERMINGLED MASS OF BRUSH, TRESS, TRIMMINGS ETC.

BARRIER SHALL BE POROUS ENOUGH TO ALLOW WATER TO

FILTER THROUGH. SECURE BY PLACING MATERIAL (TREES, LOGS

ETC) ON TOP OF AND THROUGHOUT THE BRUSH.

7. ADJOIN BRUSH BARRIER WITH ROADWAY SLOPE ON THE LOW END

AS NEEDED TO CONTAIN SEDIMENTS.

NOTES

1. ALL PITS AND QUARRIES SHALL BE APPROVED IN WRITING BY THE CO PRIOR TO

EXPLORATION, CLEARING OR DEVELOPMENT.

2. REMOVE ALL OVERBURDEN TO SOLID ROCK FOR A MINIMUM DISTANCE OF 15' FROM

THE WORKING FACE.

3. SLOPE THE CUT BANK OF THE OVERBURDEN TO THE NATURAL ANGLE OF REPOSE BUT

IN NO CASE STEEPER THAN 1:1.

4. WITHIN THE CLEARING LIMITS:

4.1. MAXIMUM STUMP HEIGHT SHALL BE IN ACCORDANCE WITH SPECIFICATIONS.

4.2. STABLE TREES UP TO 6" (DBH) NEED NOT BE CUT IF THEY WILL NOT INTERFERE

WITH BACK SLOPE STABILITY.

4.3. STUMPS AND BRUSH MAY BE LEFT IN PLACE, EXCEPT THAT ALL STUMPS THAT

PROTRUDE FROM EXCAVATED BANKS OR THAT HAVE THE POTENTIAL TO BECOME

DISLODGED AT ANY LATER DATE SHALL BE REMOVED.

5. DISPOSE OF OR STOCKPILE FOR LATER USE ALL OVERBURDEN, CLEARING,

MERCHANTABLE TIMBER AND GRUBBING DEBRIS AS SHOWN ON THE QUARRY

DEVELOPMENT PLAN.

6. FELL ALL DEAD TREES AND SNAGS WHICH ARE SUFFICIENTLY TALL TO REACH THE

WORK AREA.

7. LEAVE THE PIT/QUARRY IN A NEAT, ORDERLY AND WELL-DRAINED CONDITION.

REMOVE ALL OVERHANGS AND LOOSE ROCK.

8. AFTER EXCAVATION IS COMPLETE CLEAN THE AREA AND LEAVE AS SHOWN ON THE

QUARRY DEVELOPMENT PLAN. TREAT ANY ACCESS ROAD AS SHOWN ON THE QUARRY

DEVELOPMENT PLAN.

9. TEST SHOTS OF 1300 TO 2600 CY ARE REQUIRED AT ALL QUARRY SITES IF DESCRIBED

IN THE SPECIFICATIONS.

10. LEAVE NO MORE THAN 5% BY VOLUME OF OVERSIZE MATERIAL IN THE QUARRY.

BREAK DOWN ANY MATERIAL OVER THIS VOLUME AND USE AS SPECIFIED IN SECTIONS

651.

11. PROVISIONS FOR FUTURE QUARRY DEVELOPMENT ACCESS WILL BE PROVIDED,

UNLESS THIS REQUIREMENT IS WAVED BY THE CO.

12. INSTALL AND MAINTAIN A COMMERCIALLY AVAILABLE RAIN GAUGE MEASURING IN

UNITS OF INCHES AND FRACTIONS OF INCHES IN ACCORDANCE WITH SECTION 205.08.

13. HAUL WILL NOT BE ALLOWED BEYOND DESIGNATED SOURCES UNLESS OTHERWISE

SHOWN ON THE DRAWINGS OR AGREED TO BY THE CO.

DEVELOPMENT PLAN

1. ALL MERCHANTABLE TIMBER WILL BE REMOVED FROM THE QUARRY SITE AND DECKED IN THE

MUSKEG LEFT OF XX+XX

2. OVERBURDEN WILL NOT BE PLACED IN THE SMALL STREAM BORDERING THE QUARRY.

3. DEVELOPMENT WILL COMPLY WITH THE GENERAL NOTES SHOWN ON THE PIT & QUARRY

DEVELOPMENT TYPICAL SHEET.

4. TEST SHOT OF APPROXIMATELY XXXX CY IS PLANNED.

REHABILITATION PLAN

1. THE ACCESS ROAD WILL BE OBLITERATED BY CUTTING A DITCH AT THE JUNCTION OF THE

ACCESS ROAD WITH ROAD NO. XXXX AND BY ROUGHING UP THE ACCESS ROAD SURFACE.

2. ALL OVERSIZE ROCK WILL BE PLACED AGAINST THE SIDES OF THE QUARRY NEXT TO THE

BACKWALL BENCH.

3. A MINIMUM OF 12" OF OVERBURDEN WILL BE EVENLY SPREAD OVER THE QUARRY FLOOR.

4. ALL DISTURBED AREAS, SUCH AS OVERBURDEN PILES, BENCH SURFACES, AND ACCESS ROAD

SURFACES WILL BE SEEDED AND FERTILIZED IN ACCORDANCE WITH SPECIFICATIONS.

5. PROVISIONS FOR FUTURE QUARRY ACCESS WILL BE PROVIDED UNLESS THIS REQUIREMENT IS

WAIVED BY THE COR.
