6. CONTRACTOR MUST PROVIDE HORIZONTAL AND VERTICAL LOCATIONS OF UTILITIES ENCOUNTERED OR ABANDONED ON

RECORD DRAWINGS AT THE COMPLETION OF WORK.

IT IS THE CONTRACTOR'S RESPONSIBILITY TO CONTROL DUST THROUGHOUT THE CONSTRUCTION PERIOD. DUST CONTROL METHODS MUST INCLUDE, BUT BE NOT LIMITED TO, SPRINKLING WATER ON EXPOSED AREAS, COVERING LOADED DUMP TRUCKS LEAVING THE SITE, AND TEMPORARY MULCHING. DUST CONTROL MEASURES MUST BE UTILIZED SO AS TO PREVENT THE MIGRATION OF DUST FROM THE SITE TO ABUTTING AREAS. FUGITIVE DUST MUST BE CONTROLLED IN ACCORDANCE WITH NHDES EROSION AND SEDIMENTATION CONTROL BEST PRACTICES.

DUST CONTROL:

1. THE CONCRETE CONTRACTOR SHOULD BE ENCOURAGED WHERE POSSIBLE, TO USE WASHOUT FACILITIES AT THEIR OWN PLANT

OR DISPATCH FACILITY.

ANTICIPATED WASHOUT WATER.

3. WASHOUT AREAS MUST ALSO BE PROVIDED FOR PAINT AND STUCCO OPERATIONS.

4. ATTEMPTS MUST BE MADE TO LOCATE WASHOUT AREA A LEAST 50 YARDS AWAY FROM STORM DRAINS AND WATER WAYS

WHENEVER POSSIBLE.

5. INSPECT WASHOUT FACILITIES DAILY TO DETECT LEAKS OR TEARS AND TO IDENTIFY WHEN MATERIALS NEED TO BE REMOVED.

CONCRETE WASHOUT AREA:

1. DISCHARGES FROM FIRE-FIGHTING ACTIVITIES

2. FIRE HYDRANT FLUSHINGS

3. WATERS USED TO WASH VEHICLES WHERE DETERGENTS ARE NOT USED

4. WATER USED TO CONTROL DUST

SEQUENCE OF MAJOR ACTIVITIES

THE CONSTRUCTION SEQUENCE MUST LIMIT THE DURATION AND AREA OF DISTURBANCE.

1. CONSTRUCT TEMPORARY AND PERMANENT SEDIMENT, EROSION CONTROL MEASURES. EROSION AND SEDIMENT CONTROL MEASURES MUST BE INSTALLED PRIOR TO ANY EARTH MOVING OPERATIONS THAT MUST INFLUENCE STORMWATER RUNOFF SUCH AS

- NEW CONSTRUCTION

- EXCAVATION WORK

2. CLEAR AND DISPOSE OF DEBRIS.

3. ALL ROADS AND PARKING AREAS MUST BE STABILIZED WITHIN 72 HOURS OF ACHIEVING FINISHED GRADE.

4. BEGIN PERMANENT AND TEMPORARY SEEDING AND MULCHING. ALL CUT AND FILL SLOPES MUST BE SEEDED AND MULCHED WITHIN 72 HOURS OF

ACHIEVING FINISHED GRADE.

5. DAILY, OR AS REQUIRED, CONSTRUCT TEMPORARY BERMS, DRAINS, DITCHES, SILT FENCES, SEDIMENT TRAPS, ETC., MULCH AND SEED AS REQUIRED.

6. INSPECT AND MAINTAIN ALL EROSION AND SEDIMENT CONTROL MEASURES.

7. COMPLETE PERMANENT SEEDING AND LANDSCAPING.

8. REMOVE TRAPPED SEDIMENTS FROM COLLECTOR DEVICES AS APPROPRIATE AND THEN REMOVE TEMPORARY EROSION CONTROL MEASURES.

EROSION AND SEDIMENT CONTROLS AND STABILIZATION PRACTICES

A. STABILIZATION MUST BE INITIATED ON ALL LOAM STOCKPILES AND DISTURBED AREAS WHERE CONSTRUCTION ACTIVITY MUST NOT OCCUR FOR MORE

THAN TWENTY ONE (21) CALENDAR DAYS. BY THE FOURTEENTH (14TH) DAY AFTER CONSTRUCTION ACTIVITY HAS PERMANENTLY OR TEMPORARILY CEASED

IN THAT AREA. STABILIZATION MEASURES TO BE USED INCLUDE:

1. TEMPORARY SEEDING

2. MULCHING

B. DURING CONSTRUCTION, RUNOFF MUST BE DIVERTED AROUND THE SITE WITH EARTH DIKES, PIPING OR STABILIZED CHANNELS WHERE POSSIBLE. SHEET RUNOFF FROM THE SITE MUST BE FILTERED THROUGH HAYBALE BARRIERS AND SILT FENCES. ALL STORM DRAIN BASIN INLETS MUST BE PROVIDED WITH FLARED END SECTIONS AND TRASH RACKS. THE SITE MUST BE STABILIZED FOR THE WINTER BY NOVEMBER 15.

C. AN AREA MUST BE CONSIDERED STABLE WHEN ONE OF THE FOLLOWING HAS OCCURRED:

1. BASE COURSE GRAVELS HAVE BEEN INSTALLED IN AREAS TO BE PAVED.

2. A MINIMUM OF 85% VEGETATED GROWTH HAS BEEN ESTABLISHED.

3. A MINIMUM OF 3" OF NON-EROSIVE MATERIAL SUCH STONE OR RIPRAP HAS BEEN INSTALLED.

4. EROSION CONTROL BLANKETS HAVE BEEN PROPERLY INSTALLED.

D. WINTER STABILIZATION PRACTICES (NOVEMBER 15TH THROUGH MAY 1ST):

1. ALL PROPOSED POST-DEVELOPMENT VEGETATED AREAS WHICH DO NOT EXHIBIT A MINIMUM OF 85% VEGETATED GROWTH BY NOVEMBER 15TH, OR

WHICH ARE DISTURBED AFTER NOVEMBER 15TH. MUST BE STABILIZED BY SEEDING AND INSTALLING EROSION CONTROL BLANKETS ON SLOPES GREATER THAN 4:1, AND SEEDING AND PLACING 3 TO 4 TONS OF MULCH PER ACRE, SECURE WITH ANCHOR NETTING, ELSEWHERE.

2. ALL DITCHES OR SWALES WHICH DO NOT EXHIBIT A MINIMUM OF 85% VEGETATIVE GROWTH BY OCTOBER 15TH, OR WHICH ARE DISTURBED AFTER OCTOBER 15TH, MUST BE STABILIZED WITH STONE OR EROSION CONTROL BLANKETS APPROPRIATE FOR THE DESIGN FLOW CONDITION.

3. AFTER NOVEMBER 15TH, INCOMPLETE ROAD OR PARKING SURFACES MUST BE PROTECTED WITH A MINIMUM OF 3-INCHES OF CRUSHED GRAVEL PER NHDOT ITEM 304.3, OR IF CONSTRUCTION IS TO CONTINUE THROUGH THE WINTER SEASON BE CLEARED OF ANY ACCUMULATED SNOW AFTER EACH

STORM EVENT.

OFF SITE VEHICLE TRACKING

THE CONTRACTOR MUST CONSTRUCT STABILIZED CONSTRUCTION ENTRANCE(S) PRIOR TO ANY EXCAVATION ACTIVITIES. DEBRIS AND SEDIMENT TO BE CLEARED

FROM STABILIZED CONSTRUCTION ENTRANCE VICINITY DAILY.

INSTALLATION- MAINTENANCE AND INSPECTION PROCEDURES OF EROSION AND SEDIMENT CONTROLS

A. GENERAL

THESE ARE THE GENERAL INSPECTION AND MAINTENANCE PRACTICES THAT MUST BE USED TO IMPLEMENT THE PLAN.

1. ALL SWALES MUST BE STABILIZED PRIOR TO DIRECTING FLOW TO THEM.

2. THE SMALLEST PRACTICAL PORTION OF THE SITE MUST BE DENUDED AT ONE TIME. UNDER NO CIRCUMSTANCES MUST MORE THAN 5.0 ACRES OF THE

PROJECT SITE BE UNSTABILIZED AT ONE TIME.

F. MULCHING

1. TIMING

IN ORDER FOR MULCH TO BE EFFECTIVE, IT MUST BE IN PLACE PRIOR TO MAJOR STORM EVENTS. THERE ARE TWO (2) TYPES OF

STANDARDS WHICH MUST BE USED TO ASSURE THIS:

a. APPLY MULCH PRIOR TO ANY STORM EVENT. IT WILL BE NECESSARY TO CLOSELY MONITOR WEATHER PREDICTIONS, USUALLY BY

CONTACTING THE NATIONAL WEATHER SERVICE IN CONCORD, TO HAVE ADEQUATE WARNING OF SIGNIFICANT STORMS.

b. REQUIRED MULCHING WITHIN A SPECIFIED TIME PERIOD. THE TIME PERIOD CAN RANGE FROM 14 TO 21 DAYS OF INACTIVITY ON A

AREA, THE LENGTH OF TIME VARYING WITH SITE CONDITIONS. PROFESSIONAL JUDGMENT MUST BE USED TO EVALUATE THE INTERACTION OF SITE CONDITIONS (SOIL ERODIBILITY, SEASON OF YEAR, EXTENT OF DISTURBANCE, PROXIMITY TO SENSITIVE RESOURCES, ETC.) AND THE POTENTIAL IMPACT OF EROSION ON ADJACENT AREAS TO CHOOSE AN APPROPRIATE TIME RESTRICTION.

2. APPLICATION RATE

MULCH MUST BE APPLIED AT A RATE OF BETWEEN 1.5 TO 2 TONS PER ACRE, OR 90 TO 100 POUNDS PER 1000 SQUARE FEET. THE MINIMUM MULCH REQUIREMENT, REGARDLESS OF APPLICATION RATE IS THAT SOIL MUST NOT BE VISIBLE.

3. GUIDELINES FOR WINTER MULCH APPLICATION.

WHEN MULCH IS APPLIED TO PROVIDE PROTECTION OVER WINTER (PAST THE GROWING SEASON) IT MUST BE AT A RATE OF 6.000 POUNDS OF HAY OR STRAW PER ACRE. A TACKIFIER MAY BE ADDED TO THE MULCH. NO MULCH IS TO BE APPLIED OVER MORE THAN TWO (2) INCHES OF SNOW. IF SNOW DEPTH IS GREATER THAN TWO (2) INCHES IT MUST BE REMOVED BEFORE MULCHING.

4. MAINTENANCE

ALL MULCHES MUST BE INSPECTED PERIODICALLY, IN PARTICULAR AFTER RAINSTORMS, TO CHECK FOR RILL EROSION. IF LESS THAN 90X OF THE SOIL SURFACE IS COVERED BY MULCH. ADDITIONAL MULCH MUST BE IMMEDIATELY APPLIED.

EXCELSIOR MATTING, OR APPROVED EQUAL, MUST BE USED IN PLACE OF MULCH ON ALL SLOPES STEEPER THAN 3:1.

6. SLOPES

ALL SLOPES GREATER THAN 15% DURING THE REGULAR CONSTRUCTION SEASON ARE TO HAVE NETTING OVER MULCH OR COMBINATION EROSION CONTROL MAT USED (MULCH AND NET). THIS APPLIES TO ALL SLOPES GREATER THAN 8% AFTER OCTOBER 1. MULCHING IS

REQUIRED OVER HYDROSEEDING.

APPLYING FERTILIZER, LIME AND SEED.

c. APPLY SEED UNIFORMLY BY HAND. CYCLONE SEEDER, OR HYDROSEEDER (SLURRY INCLUDING SEED AND FERTILIZER).

HYDROSEEDINGS, WHICH INCLUDE MULCH,MAY BE LEFT ON SOIL SURFACE. SEEDING RATES MUST BE INCREASED 10% WHEN

HYDROSEEDING.

3. MAINTENANCE

TEMPORARY SEEDINGS MUST BE PERIODICALLY INSPECTED. AT A MINIMUM, 95% OF THE SOIL SURFACE SHOULD BE COVERED BY VEGETATION. IF ANY EVIDENCE OF EROSION OR SEDIMENTATION IS APPARENT, REPAIRS MUST BE MADE AND OTHER TEMPORARY

MEASURES USED IN THE INTERIM (MULCH, FILTER BARRIERS, CHECK DAMS, ETC.).

H. PERMANENT MULCHING

1. TIMING

a. APPLYING PLANT RESIDUES OR OTHER SUITABLE MATERIALS THAT RESIST DECOMPOSITION SUCH AS WOOD CHIPS OR CRUSHED STONE TO THE SOIL SURFACE WHERE VEGETATION STABILIZATION IS EITHER IMPRACTICAL OR DIFFICULT TO ESTABLISH.

b. WINTER STABILIZATION MUST MEET OR EXCEED THE FOLLOWING REQUIREMENTS.

2. CONSIDERATIONS

NOT INTENDED FOR AREAS OF CONCENTRATED FLOWS.

b. IF WOOD CHIPS ARE USED IN LANDSCAPED AREAS (TREES & SHRUBS). A SUPPLEMENTAL APPLICATION OF CHEMICAL FERTILIZER SHOULD BE APPLIED AT A RATE OF TWO POUNDS OF 5-10-5 PER 100 SQUARE FEET OF MULCH.

c. IF CRUSHED STONE IS USED, A PLASTIC FILTER CLOTH MUST BE PLACED BETWEEN THE GROUND AND THE STONE.
