NOTES

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

EXPLORATION, CLEARING OR DEVELOPMENT.

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

FROM THE WORKING FACE.

SLOPE THE CUT BANK OF THE OVERBURDEN TO THE NATURAL ANGLE OF REPOSE

BUT IN NO CASE STEEPER THAN 1:1.

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.

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

MERCHANTABLE TIMBER AND GRUBBING DEBRIS AS SHOWN ON THE QUARRY

DEVELOPMENT PLAN.

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

WORK AREA.

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

REMOVE ALL OVERHANGS AND LOOSE ROCK.

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.

TEST SHOTS OF 1300 to 2600 CUBIC YARDS ARE REQUIRED AT ALL QUARRY SITES

IF DESCRIBED IN THE SPECIFICATIONS.

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.

PROVISIONS FOR FUTURE QUARRY DEVELOPMENT ACCESS WILL BE PROVIDED,

UNLESS THIS REQUIREMENT IS WAVED BY THE CO.

INSTALL AND MAINTAIN A COMMERCIALLY AVAILABLE RAIN GAUGE MEASURING IN

UNITS OF INCHES AND FRACTIONS OF INCHES IN ACCORDANCE WITH SECTION

205.08.

HAUL WILL NOT BE ALLOWED BEYOND DESIGNATED SOURCES UNLESS OTHERWISE

SHOWN ON THE DRAWINGS OR AGREED TO BY THE CO.

SEED AND FERTILIZE ALL DISTURBED AREAS SUCH AS OVERBURDEN PILES AND

BENCH SURFACES IN ACCORDANCE WITH SECTION 625.

NOTES:

SILT FENCE CONSISTS OF WOVEN WIRE FENCE FABRIC WITH A MAXIMUM 6 INCHES MESH, MINIMUM HEIGHT

30 INCHES.

THE CO MAY REQUIRE ADJUSTMENTS TO ACTUAL LENGTHS OR LOCATIONS TO FIT FIELD CONDITIONS.

INSPECT SILT FENCES AFTER EACH RUNOFF EVENT AND IMMEDIATELY REPAIR ALL EROSION ALONG EDGES

AND BOTTOM.

ACCUMULATED DEPTH OF SEDIMENT SHALL NOT EXCEED ONE HALF THE ORIGINAL HEIGHT OF THE SILT FENCE.

IN AREAS DESIGNATED FOR BRUSH BARRIERS, LIMIT CLEARING TO TREES, SHRUBS AND PLANTS LESS THAN 4

INCHES IN DIAMETER. GRUBBING SHALL NOT BE PERFORMED IN THESE AREAS.

BRUSH BARIER SHALL BE CONSTRUCTED APPROX. PARALLEL TO ORIGINAL GROUND CONTOUR. USE WELL-INTERMINGLED MASS OF BRUSH, TREES, TRIMMINGS, ETC. BARRIER SHALL BE POROUS ENOUGH TO ALLOW WATER TO FILTER THROUGH. SECURE BY PLACING HEAVIER MATERIAL (TREES, LOGS, ETC.) ON TOP

OF AND THROUGHOUT THE BRUSH.

ADJOIN BRUSH BARRIER WITH ROADWAY SLOPE ON THE LOW END AS NEEDED TO CONTAIN SEDIMENTS.
