PIT AND QUARRY DEVELOPMENT NOTES

1. ALL PITS AND QUARRIES SHALL BE APPROVED IN WRITING BY THE C.O.

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:

- MAXIMUM STUMP HEIGHT SHALL BE IN ACCORDANCE WITH SPECIFICATIONS.

- STABLE TREES UP TO 6" dbh NEED NOT BE CUT IF THEY WILL NOT INTERFERE

WITH BACK SLOPE STABILITY.

- 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. ROCK LOOSENED BY

BLASTING OPERATIONS SHALL BE SCALED FROM FACES PRIOR TO LEAVING

THE SITE. MACHINE SCALING IS REQUIRED.

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. NO MORE THAN 5% BY VOLUME OF OVERSIZE MATERIAL SHALL REMAIN IN

THE QUARRY. ALL OTHER MATERIAL SHALL BE BROKEN DOWN AND USED AS

SPECIFIED IN SPECIFICATIONS 203, 304, AND 611.

10. SEED AND FERTILIZE ALL DISTURBED AREAS SUCH AS OVERBURDEN PILES

AND BENCH SURFACES. SEEDING AND FERTILIZER IS INCIDENTAL TO PIT

AND QUARRY DEVELOPMENT PLAN.

11. PROVISIONS FOR FUTURE QUARRY DEVELOPMENT ACCESS WILL BE

PROVIDED, UNLESS THIS REQUIREMENT IS WAVED BY THE CO.

DEVELOPMENT PLAN

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

THE MUSKEG AS DIRECTED BY COR

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

DEVELOPMENT TYPICAL SHEET.

3. TEST SHOT OF APPROX. 2000 CU. YD. IS PLANNED.

REHABILITATION PLAN

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

ACCESS ROAD 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-IN 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.
