IMPLEMENTATION OF SOIL EROSION AND SEDIMENT CONTROL MEASURES

(GENERAL SEQUENCE OF CONSTRUCTION OPERATIONS)

1. NOTIFY MORRIS COUNTY SCD IN WRITING AT LEAST 72 HOURS IN ADVANCE OF ANY

SOIL DISTURBANCE. (1 DAY)

2. REMOVE ANY TREES SO INDICATED WITHIN AREA DESIGNATED "LIMIT OF PROJECT".

(ACTIVITIES ARE LIMITED TO TREE CUTTING AND REMOVAL AND DO NOT CALL FOR

SOIL DISTURBANCE. FURTHERMORE, THE REMOVAL OF TREES SHALL NOT BE

PERMITTED BETWEEN APRIL 1 AND NOVEMBER 15 IN ACCORDANCE WITH

RESTRICTIONS TO PROTECT THE INDIANA BAT, AN ENDANGERED SPECIES;

COORDINATE WITH BASE'S ONSITE BIOLOGIST AS NECESSARY). (WEEKS 1 - 12)

3. PLACE SUPER SILT FENCE, GENERALLY ALONG PERIMETER OF SITE DISTURBANCE.

(WEEKS 1 - 12, CONCURRENT WITH ITEM #2)

4. DEMOLISH EXISTING BUILDINGS AND INFRASTRUCTURE. (WEEKS 12 - 36)

5. CONSTRUCT NEW UTILITIES, STORM SEWER, INLETS AND OUTFALL AS PER

CONSTRUCTION DRAWINGS. (WEEKS 36 - 52)

6. CONSTRUCT NEW BUILDINGS, ROADWAY AND PARKING AS PER CONSTRUCTION

PLANS. (WEEKS 36 - 91, CONCURRENT WITH ITEM #5)

7. INSTALL ANY REMAINING SITE IMPROVEMENTS - i.e., SIGNAGE, TOPSOIL & SEEDING, ETC. - AND REMOVE ANY S.E.S.C. MEASURES FOLLOWING INSPECTION BY MORRIS

COUNTY SCD. (WEEKS 91 - 104).

DURATION OF PROJECT: APPROXIMATELY TWO (2) YEARS OR LESS.

STANDARD FOR TOPSOIL

TOPSOILING ENTAILS THE DISTRIBUTION OF SUITABLE QUALITY SOIL ON AREAS TO BE VEGETATED.

TO IMPROVE THE SOIL MEDIUM FOR PLANT ESTABLISHMENT AND MAINTENANCE.

TOP SOIL SHOULD BE USED WHERE SOILS ARE: SANDS, GRAVELY SOILS, CLAYS, SILTY CLAYS, VERY SHALLOW

OR WHERE THEY ARE EXTREMELY ACID (LESS THAN 4.0) OR SALTY (CONDUCTIVITY GREATER THAN 1.0

MILL MHOS PER CENTIMETER); OR WHERE TOPSOIL IS AVAILABLE ON SITE AND ASSURANCE OF IMPROVED

TOPSOIL SHOULD BE FRIABLE AND LOAMY, FREE OF DEBRIS, OBJECTIONABLE WEEDS AND STONES, AND

CONTAIN NO TOXIC SUBSTANCE THAT MAY BE HARMFUL TO PLANT GROWTH. A PH RANGE OF 5.0-7.5 IS

ACCEPTABLE. SOLUBLE SALTS SHOULD NOT BE EXCESSIVE (CONDUCTIVITY LESS THAN 0.5 MILLIMHOS PER

CENTIMETER). TOPSOIL HAULED IN FROM OFF SITE SHOULD HAVE A MINIMUM ORGANIC MATTER CONTENT

OF 2.75 PERCENT. ORGANIC MATTER CONTENT MAY BE RAISED BY ADDITIVES.

FIELD EXPLORATION SHOULD BE MADE TO DETERMINE WHETHER QUANTITY AND OR QUALITY OF SURFACE

STRIPPING SHOULD BE CONFINED TO THE IMMEDIATE CONSTRUCTION AREA.

WHERE FEASIBLE, LIME MAY BE APPLIED BEFORE STRIPPING AT A RATE DETERMINED BY SOIL TESTS

TO BRING THE SOIL PH TO 6.5. IN LIEU OF SOIL TESTS, SEE LIME RATE GUIDE IN SEEDBED

PREPARATION FOR PERMANENT VEGETATIVE COVER, PAGE 3.2.1.

VEGETATIVE GROWTH IS DESIRED.

DEFINITION

PURPOSE

1. THE CONTRACTOR SHALL PREPARE A PLAN FOR THE PROPER DEWATERING OF

EACH STREAM CROSSING PRIOR TO EXCAVATING THE STREAM BED. PLAN

SHALL BE FORWARDED TO THE ENGINEER AND MORRIS COUNTY SOIL

CONSERVATION DISTRICT FOR APPROVAL. THE DISTRICT SHALL BE NOTIFIED

FOR INSPECTION PRIOR TO EACH STREAM CROSSING CONSTRUCTION.

2. ANY AREAS USED FOR THE CONTRACTOR'S STAGING, INCLUDING BUT NOT

LIMITED TO, TEMPORARY STORAGE OF STOCKPILED MATERIALS ( E.G. CRUSHED

STONE, QUARRY PROCESS STONE, SELECT FILL, EXCAVATED MATERIALS, ETC.),

SHALL BE ENTIRELY PROTECTED BY A SILT FENCE ALONG THE LOW ELEVATION

SIDE TO CONTROL SEDIMENT RUNOFF.

3. PRIOR TO CONSTRUCTION, THE CONTRACTOR SHALL BE RESPONSIBLE FOR

NOTIFYING THE MORRIS COUNTY SOIL CONSERVATION DISTRICT OF ANY

STAGING AND/OR STOCKPILE LOCATION AREAS AND FOR OBTAINING A SOIL

EROSION AND SEDIMENT CONTROL CERTIFICATION FOR THESE AREAS.

4. A CRUSHED STONE, VEHICLE WHEEL-CLEANING BLANKET SHALL BE INSTALLED

AT THE CONTRACTOR'S STAGING YARD AND/OR STOCKPILE AREAS TO PREVENT

OFF-SITE TRACING OF SEDIMENT BY CONSTRUCTION VEHICLES ONTO PUBLIC

ROADS. BLANKET SHALL BE 15 FT. X 50 FT. X 6 IN. (MINIMUM), CRUSHED STONE

2-1/2 INCHES IN DIAMETER. SAID BLANKET SHALL BE UNDERLAIN WITH A

SUITABLE SYNTHETIC SEDIMENT FILTER FABRIC AND MAINTAINED IN GOOD

ORDER.

MORRIS COUNTY SOIL CONSERVATION DISTRICT NOTES FOR ROAD WORK

WOOD - FIBER OR PAPER-FIBER MULCH AT THE RATE OF 1,500 POUNDS PER ACRE MAY BEC.

IMMEDIATELY PRIOR TO TOPSOIL DISTRIBUTION, THE SURFACE SHOULD BE SCARIFIED AND DE-COMPACTED

EMPLOY NEEDED EROSION CONTROL PRACTICES SUCH AS DIVERSIONS, GRADE STABILIZATION

STRUCTURES, CHANNEL STABILIZATION MEASURES, SEDIMENTATION BASINS, AND WATERWAYS. SEE

TOPSOIL SHOULD BE HANDLED ONLY WHEN ITS IS DRY ENOUGH TO WORK WITHOUT DAMAGING SOIL

STRUCTURE; I.E., LESS THAN FIELD CAPACITY ( SEE GLOSSARY).

A UNIFORM APPLICATION TO A DEPTH OF 5 INCHES (UNSETTLED). SOILS WITH A PH OF 4.0 OR LESS OR

CONTAINING IRON SULFIDE SHALL BE COVERED WITH A MINIMUM DEPTH OF 12 INCHES OF SOIL HAVING

EMULSIFIED ASPHALT - (SS-1, CSS-1, CMS-2, MS-2, RS-1, RS-2, CRS-1, AND

APPLY 0.04 GAL./SQ./YD. OR 194 GAL./ACRE ON FLAT SLOPES LESS THAN 8 FEET

HIGH. ON SLOPES 8 FEET OR MORE HIGH, USE 0.075 GAL./SY. YD. OR

SYNTHETIC OR ORGANIC BINDERS - BINDERS SUCH AS CURASOL, DCA-70, PETRO-SET,

AND TERRA-TRACK MAY BE USED AT RATES RECOMMENDED BY THE MANUFACTURER TO

MULCH MATERIAL SHOULD BE UNROTTED SMALL GRAIN STRAW, HAY FREE OF SEEDS, OR SALT HAY TO

BE APPLIED AT A RATE OF 1-1/2 TO 2 TONS PER ACRE (70 TO 90 POUNDS PER 1,000 SQUARE

FEET), EXCEPT THAT WHERE A CRIMPER IS USED INSTEAD OF A LIQUID MULCH-BINDER (TACKIFYING

OR ADHESIVE AGENT), THE RATE OF APPLICATION MUST BE DOUBLED THE LOWER RATE. MULCH

SPREAD UNIFORMLY BY HAND OR MECHANICALLY SO THAT APPROXIMATELY 75% TO 95% OF THE SOIL

SURFACE WILL BE COVERED. FOR UNIFORM DISTRIBUTION OF HAND-SPREAD MULCH, DIVIDE AREA

INTO APPROXIMATELY 1,000 SQUARE FEET SECTIONS AND DISTRIBUTE 70 TO 90 POUNDS, WITHIN EACH

MULCH ANCHORING SHOULD BE ACCOMPLISHED IMMEDIATELY AFTER PLACEMENT TO MINIMIZE LOSS BY

WIND OR WATER. THIS MAY BE DONE BY ONE OF THE FOLLOWING METHODS, DEPENDING UPON THE

PEG AND TWINE - DRIVE 8 TO 10 INCH WOODEN PEGS TO WITHIN 2 TO 3 INCHES OF THE SOIL

SURFACE EVERY 4 FEET IN ALL DIRECTIONS. STAKE MAY BE DRIVEN BEFORE OR AFTER

APPLYING MULCH. SECURE MULCH TO SOIL SURFACE BY STRETCHING TWINE BETWEEN PEGS IN A

CRISS-CROSS AND A SQUARE PATTERN. SECURE TWINE NETTING AROUND EACH PEG WITH TWO

MULCH NETTINGS - STAPLE PAPER, JUTE, COTTON, OR PLASTIC NETTINGS TO THE SOIL

SURFACE. USE A DEGRADABLE NETTING IN AREAS TO BE MOWED.

CRIMPER (MULCH ANCHORING TOOL) - A TRACTOR DRAWN IMPLEMENT, SOMEWHAT LIKE A DISC-

HARROW, ESPECIALLY DESIGNED TO PUSH OR CUT SOME OF THE BROADCAST LONG FIBER MULCH 3

TO 4 INCHES INTO THE SOIL SO AS TO ANCHOR IT AND LEAVE PART STANDING UPRIGHT. THIS

TECHNIQUE IS LIMITED TO AREAS TRAVERSABLE BY A TRACTOR, WHICH MUST OPERATE ON THE

CONTOUR OF SLOPE. STRAW MULCH RATE MUST BE 3 TONS PER ACRES. NO TACKIFYING OR

LIQUID MULCH-BINDER - MAY BE USED TO ANCHOR SALT HAY, HAY OR STRAW MULCHES.

APPLICATION SHOULD BE HEAVIER AT EDGES WHERE WIND CATCHES THE MULCH, IN VALLEYS,

AND AT CRESTS OF BANKS. REMAINDER OF AREA SHOULD BE UNIFORM IN APPEARANCE

OR MORE ROUND TURNS.
