may vary at discretion of Landscape Architect depending on weather conditions.)
G. Soil Preparation.
1. Soil surface must be free of rocks, debris, and other foreign materials.
2. Soils must have proper moisture control to assure proper germination and growth.
3. Soil surface must be compacted to a depth of at feast 6 Inches.
4. Soil preparation depends on soil conditions at time of s Various tools
eeding.
may be necessary to achieve surface finish.
5. Surface of soil shall be level and large voids eliminated to applying fertilizer, lime and seed.
H. Applying fertilizer, lime and seed.
1. Work fertilizer and lime into soil to a depth of 2 - 3 inches.
2. Apply seed carefully and cover seed with 1/4 Inch soil, apply seed carefully
and avoid covering seed more than 1/4 Inch.
3. A ply mulch at rate of 2 tons per acre following seeding.
4. Water as necessary to ensure adequate moisture for germination and growth.
5. Reseed as necessary until a good stand of grass is achieved.

D. Water as necessary to ensure adequate growth and development.
*Maintenance fertilizer - apply 200 Ibs of 12 -12 -12 or equivalent.
Erosion and Sediment Control Sequence
1. Assign an on -site person trained in erosion control proceedures with the daily responsibility
and authority to ensure that erosion /sediment control practices are installed according to this
sequence schedule. 327 IAC 15 -5 requires that a Pollution Prevention Plan monitoring log
and permit information be posted at the project site.
2. Contact Indiana Underground Planned Protection Systems, Inc. ( "Holey Moley") for
underground Utility locations. (1- 800 - 382 -5544)
3. Before opening up the site, first evaluate, mark and protect important trees and associated
root zones, unique areas to be preserved (i.e. wetlands), or existing vegetation suitable for use
as filter strips especially in perimeter areas).
4. Install sediment basins or traps around the perimeter of the site and diversions above the
site to direct water from undisturbed areas away from the sediment traps while conveying
sediment -laden runoff from disturbed areas to the traps.
5. Install an adequate and stable construction entrance / exit drive from the construction site
to keep mud and sediment off public roads. Dust shall be kept to a minimum by utilizing
sprinkling, Calcium Chloride, vegetative cover, spray on adhesives or other approved methods.
6. Install the main runoff conveyance system with inlet and outlet protection devices to convey
storm runoff through the site without creating gullies and to prevent damage to open channels.
Sides of Swales, mounds and ponds to be seeded and mulched upon completion. Temporary
seeding shall be required for all swales and disturbed areas that connot be final seeded within
a time period that will prevent slope erosion. For temporary seeding, the contractor shall utilize
a fast growing seed of either oats, annual rye grass, wheat or rye depending on time of year.
Disturbed areas shall be kept to a minimum at all times.
7. As soon as the storm drain system is functional, install drain inlet protections, which trap
sediment on -site in shallow pools while allowing high water flows to enter the system.
8. Once erosion and sediment control measures are in place, begin land clearing followed
immediately by grading. Do not leave large areas unprotected for more than 7 days.
9. As grading progresses, install additional traps, silt fences, slope drains, temporary
diversions, and other runoff control measures -at appropriate locations to keep sediment
contained on -site.
10. Immediately after grading, apply surface stabilization practices on all graded areas, using
permanent measures in accordance with the erosion control plan. However, if weather delays
permanent stabilization, temporary seeding and /or mulching may be necessary as a stop -qop
measure. Also stabilize (using temporary seeding /mulching or other suitable means) any
disturbed area where active construction will not take place for 30 working days.
11. After construction and final grading, landscape and permanently stabilize all disturbed
sites, including borrow and disposal areas. Also remove temporary runoff control structures
and any unstable sediment around them, and vegetate those areas.

ADDITIONAL STORMWATER POLLUTION PREVENTION MEASURES
CRIPTION AND PURPOSE
TO PREVENT OR REDUCE THE AMOUNT OF CONTAMINATION TO STORMWATER RESULTING FROM
VEHICLE AND EQUIPMENT MAINTENANCE BY MAINTAINING A "DRY AND CLEAN SITE'. THE BEST
PRACTICE WOULD BE TO PERFORM MAINTENANCE ACTIVITIES AT AN OFFSITE FACILITY WHENEVER
POSSIBLE. IF THIS OPTION IS NOT FEASIBLE, THEN WORK SHOULD BE PERFORMED ONLY IN
DESIGNATED AREAS, WHILE PROVIDING ADEQUATE COVER FOR MATERIALS STORED OUTSIDE,
ROUTINELY CHECKING FOR LEAKS AND SPILLS, AND CONTAINING AND CLEANING UP ALL SPILLS
IMMEDIATELY.
SUITABLE APPLICATIONS
THESE PROCEDURES ARE APPUCABLE FOR ALL CONSTRUCTION PROJECTS WHERE AN ONSITE
STAGING YARD AREA IS NECESSARY FOR THE STORAGE AND MAINTENANCE OF HEAVY
CONSTRUCTION EQUIPMENT AND VEHICLES.
LIMITATIONS
VEHICLE AND EQUIPMENT MAINTENANCE SHOULD ONLY BE PERFORMED ONSITE WHEN IT IS
IMPRACTICAL TO SEND THEM OFFSITE FOR MAINTENANCE AND REPAIR. TRANSPORTING VEHICLES
AND /EQUIPMENT OFFSITE SHOULD BE DONE ONLY AT THE STABILIZED CONSTRUCTION
ENTRANCE /EXff. VEHICLE STORAGE AND EQUIPMENT MAINTENANCE PROVIDES FOR A
POTENTIALLY SIGNIFICANT SOURCE OF STORMWATER POLLUTION. ONSITE ACTIVITIES THAT CAN
CONTAMINATE STORMWATER INCLUDE GENERAL MAINTENANCE SUCH AS CHANGING OR
REPLACEMENT OF FLUIDS AND FILTERS, ENGINE REPAIR AND SERVICE, AND OUTDOOR
EQUIPMENT STORAGE OR PARKING (FROM SOURCES SUCH AS THE ENGINE, OIL, FUEL, OR
HYDRAULIC FLUID LEAKS).
IMPLEMENTATION
IF MAINTENANCE MUST OCCUR ONSITE, WORK SHOULD BE DONE ONLY IN DESIGNATED AREAS
LOCATED AWAY FROM DRAINAGE COURSES. DEDICATED MAINTENANCE AREAS SHOULD BE
PROTECTED FROM STORMWATER INFILTRATION AND RUNOFF. THE MAINTENANCE AREA SHOULD
BE LOCATED AT LEAST 50 FEET FROM DOWNSTREAM DRAINAGE FACILITIES, WATERWAYS, AND
FLOOD PLAINS.
STORE AN ADEQUATE AMOUNT OF SPILL CLEANUP MATERIALS ONSITE WHERE THEY CAN BE
READILY ACCESSIBLE.
DRIP PANS OR ABSORBENT PADS SHOULD BE USED DURING VEHICLE AND EQUIPMENT
MAINTENANCE WORK THAT INVOLVES FLUIDS, UNLESS THE MAINTENANCE WORK IS PERFORMED
OVER AN IMPERMEABLE SURFACE WITHIN THE DEDICATED MAINTENANCE AREA
USE ABSORBENT MATERIALS ON SMALL SPILL AREAS. REMOVE THE CONTAMINATED ABSORBENT
MATERIALS PROMPTLY AND DISPOSE OF THEM PROPERLY.
ALL FUELING TRUCKS AND FUELING AREAS SHALL HAVE SPILL KITS AND /OR USE OTHER
ADEQUATE SPIU. PROTECTION DEVICES.
INSPECT ONSITE VEHICLES AND EQUIPMENT DAILY AT THE BEGINNING OF EACH DAY FOR LEAKS
AND REPAIR IMMEDIATELY.
KEEP VEHICLES AND EQUIPMENT CLEAN; DO NOT ALLOW EXCESSIVE BUILD -UP OF OIL, GREASE
OR SILT MATERIALS THAT MAY CONTAMINATE OTHER PORTIONS OF THE SITE.
EMPLOYEES AND SUBCONTRACTORS SHALL BE TRAINED IN PROPER MAINTENANCE AND SPILL
MEDIATION PROCEDURES.
PROPERLY DISPOSE OF USED OILS, FLUIDS, LUBRICANTS, AND SPILL CLEANUP MATERIALS PER
LOCAL AND STATE LAWS.
SEPARATE AND RECYCLE WASTES SUCH AS GREASES, USED OIL, HYDRAUUC FLUID, OIL
FILTERS, ANTIFREEZE, CLEANING SOLVENTS, BATTERIES, AND TRANSMISSION FLUIDS. IF THESE
MATERIALS ARE STORED ONSITE, PROVIDE ADEQUATE SECONDARY CONTAINMENT AND COVERS.
DO NOT PLACE USED OIL IN AN UNAPPROVED DUMPSTER, POUR INTO A STORM DRAIN OR
WATERCOURSE, OR POUR ONTO THE GROUND.
DRIP PANS OR PLASTIC SHEETING SHOULD BE PLACED UNDER ALL VEHICLES AND EQUIPMENT
PLACED ON WATERWAY DOCKS, BARGES, OR OTHER STRUCTURES LOCATED OVER WATER BODIES
WHEN THE VEHICLE OR EQUIPMENT IS ANTICIPATED TO BE IDLE FOR MORE THAN ONE HOUR.
DO NOT BURY OR BURN USED TIRES.
SOLID WASTE MANAGEMENT
DESCRIPTION AND PURPOSE
SOLID WASTE MANAGEMENT PROCEDURES AND PRACTICES ARE DESIGNED TO PREVENT OR
REDUCE THE POTENTIAL FOR DISCHARGE OF POLLUTANTS TO STORMWATER FROM SOLID OR
CONSTRUCTION WASTE BY PROVIDING DESIGNATED WASTE COLLECTION AREAS AND CONTAINERS,
ENSURING REGULAR DISPOSAL, AND TRAINING OF EMPLOYEES AND SUBCONTRACTORS.
SUITABLE APPUQ90NS
THIS PRACTICE IS APPUCABLE FOR CONSTRUCTION SITES WHERE THE FOLLOWING WASTES ARE
GENERATED OR STORED:
SOUD WASTE GENERATED FROM DEMOLITION ACTIVITIES SUCH AS TREES OR SHRUBS,
DEMOLITION OF EXISTING STRUCTURES, AND NEW BUILDING CONSTRUCTION MATERIALS
INCLUDING CONCRETE, MASONRY, WOOD, METAL, GLASS, RUBBER, STYROFOAM, PAPER, PLASTIC,
PIPE, ELECTRICAL COMPONENTS, AND PACKAGING MATERIALS.
DOMESTIC WASTES INCLUDE: FOOD CONTAINERS, BEVERAGE CONTAINERS, COFFEE CUPS, PAPER
BAGS, PLASTIC WRAPPERS, STYROFOAM, AND CIGARETTES.
CONSTRUCTION WASTES INCLUDING BRICK, MORTAR, TIMBER, STEEL AND METAL SCRAPS, PIPE
AND ELECTRICAL CUTTINGS, NONHAZARDOUS EQUIPMENT PARTS, STYROFOAM AND OTHER
MATERIALS SEND TRANSPORT AND PACKAGE CONSTRUCTION MATERIALS,
IMPLEMENTATION
THE FOLLOWING STEPS WILL AID IN KEEPING THE SITE CLEAN AND REDUCE THE POTENTIAL
FOR STORMWATER POLLUTION:
SELECT A DESIGNATED WASTE COLLECTION AREA ONSITE THAT IS DOWNSTREAM FROM THE
STORMWATER COLLECTION SYSTEM AND AT LEAST 50 FEET AWAY FROM ALL WATERWAYS AND
FLOOD PLAINS.
INFORM THE TRASH - HAULING CONTRACTOR THAT ONLY WATERTIGHT DUMPSTERS FOR ONSITE
USE WILL BE ACCEPTED.
INSPECT DUMPSTERS WHEN THEY REACH THE SITE FOR LEAKS. REJECT ANY DUMPSTER THAT
IS NOT WATERTIGHT OR IS DEFECTIVE.
PROVIDE AN ADEQUATE NUMBER OF CONTAINERS WITH UDS OR COVERS TO KEEP RAINWATER
OUT AND TO PREVENT LOSS OF MATERIALS DUE TO WINDY CONDITIONS.
ALLOW FOR ADDITIONAL DUMPSTERS OR MORE FREQUENT PICKUPS DURING THE DEMOLITION
PHASE OF CONSTRUCTION TO INSURE TRASH MATERIALS DO NOT GET STORED ON THE
GROUND.
HAVE SITE TRASH COLLECTED DAILY. DURING RAINY AND WINDY CONDITIONS IT MAY BE
NECESSARY TO COLLECT TRASH MORE THAN ONCE A DAY.
REMOVE SOUD WASTE MATERIALS PROMPTLY FROM THE SITE SINCE EROSION AND SEDIMENT
CONTROL MEASURES TEND TO COLLECT TRASH WHICH HINDERS THE EFFECTIVENESS OF THE
EROSION CONTROL MEASURES.
INSURE THAT TOXIC UQUID WASTES SUCH AS USED OILS, SOLVENTS, AND PAINTS AND
CHEMICALS SUCH AS ACIDS, PESTICIDES, ADDITIVES, AND CURING COMPOUNDS ARE NOT
DISPOSED OF IN DUMPSTERS DESIGNATED FOR CONSTRUCTION DEBRIS BUT ARE PROPERLY
DISPOSED OF ACCORDING TO LOCAL AND STATE LAWS.
DO NOT WASH OUT DUMPSTERS ON THE CONSTRUCTION SITE. DUMPSTER CLEANING SHOULD
BE THE RESPONSIBIUTY OF THE TRASH HAULING CONTRACTOR.
ARRANGE FOR REGULAR WASTE COLLECTION BEFORE DUMPSTERS OVERFLOW. DO NOT PILE
MATERIAL ABOVE THE DUMPSTER SIDE OR ALLOW MATERIAL TO DRAPE OVER THE SIDES.
IMMEDIATELY CLEAN UP DUMPSTER SHOULD A SPILL OCCUR.
MAKE SURE THAT CONSTRUCTION WASTE IS COLLECTED, REMOVED, AND DISPOSED OF IN A
TIMELY MANOR BY AN AUTHORIZED DISPOSAL CONTRACTOR.
INJeLGI ILAI AIVU NINN i LNMIIIVL
INSPECT AND VERIFY THAT PRACTICES ARE IN PLACE PRIOR TO THE START OF EACH ASSOCIATED
ACTIVITY. WHILE ACTIVITIES ARE IN PROGRESS, INSPECT EACH PRACTICE WEEKLY TO VERIFY
CONTINUED IMPLEMENTATION.
KEEP ADEQUATE SUPPUES OF SPILL CLEANUP MATERIALS ONSITE. INSURE THAT ALL EMPLOYEES
ARE AWARE OF MATERIAL STORAGE LOCATIONS AND ACCESS CAN BE OBTAINED TO THE
MATERIALS.
MAINTAIN FLUID WASTE CONTAINERS IN LEAK PROOF CONDITION. REMOVE AND REPLACE ANY
CONTAINERS FOUND TO BE DEFECTIVE.
VEHICLES AND EQUIPMENT SHOULD BE INSPECTED AT THE START OF EACH DAY. IMMEDIATELY
REPAIR ALL LEAKS, IT IS PREFERRED THAT THE PROBLEM VEHICLE OR EQUIPMENT BE REMOVED
FROM THE PROJECT SITE FOR REPAIRS TO MINIMIZE ONSITE IMPACTS.
INSPECT EQUIPMENT FOR DAMAGED HOSES AND LEAKY GASKETS DAILY. IMMEDIATELY REPAIR OR
REPLACE FAULTY COMPONENTS.
PTRI
DES ION AND PURPOSE
VEHICLE AND EQUIPMENT FUELING PROCEDURES AND PRACTICES ARE DESIGNED TO PREVENT
FUEL SPILLS OR LEAKS AND REDUCE OR EUMINATE CONTAMINATION OF SOILS AND STORMWATER.
THIS CAN BE ACCOMPLISHED BY USING OFFSTTE FACILITIES, FUELING IN DESIGNATED ONSITE
AREAS ONLY, ENCLOSING OR COVERING STORED MATERIAL, UTIUZING SPILL CONTROLS, AND
TRAINING EMPLOYEES AND SUBCONTRACTORS IN PROPER FUELING
PROCEDURES.
UMfTATION
ONSITE VEHICLE AND EQUIPMENT FUELING SHOULD ONLY BE DONE WHEN IT IS NOT FEASIBLE TO
SEND VEHICLES AND EQUIPMENT OFFSITE FOR FUELING, VEHICLES AND EQUIPMENT ENTERING
AND EXITING THE SITE SHOULD ALWAYS BE DONE AT THE STABILIZED CONSTRUCTION
ENTRANCE /EXIT.
IMPLEMENTATION.
THE USE OF OFFSITE FUEUNG STATIONS IS ENCOURAGED WHENEVER FEASIBLE. THESE FACILITIES
ARE EQUIPPED TO HANDLE FUEUNG AND SPILLS PROPERLY. PERFORMING THIS WORK OFFSITE
MAY BE MORE ECONOMICAL BY EUMINATING THE NEED FOR A SEPARATE DESIGNATED FUEUNG
AREA AND CONTAINMENT MEASURES ONSITE.
DISCOURAGE EMPLOYEES FROM 'TOPPING -OFF" FUEL TANKS TO PREVENT UNNECESSARY SPILLS.
ABSORBENT SPILL CLEANUP MATERIALS AND SPILL KITS SHALL BE AVAILABLE IN ONSITE FUEUNG
AREAS ANO ON MOBILE FUELING TRUCKS. PROPERLY DISPOSE OF USED MATERIALS AFTER USE.
ABSORBENT PADS OR DRIP PANS SHOULD BE USED DURING VEHICLE AND EQUIPMENT FUEUNG
UNLESS THE FUEUNG IS PERFORMED OVER AN IMPERVIOUS SURFACE WITHIN A DEDICATED
FUELING AREA.
ABSORBENT MATERIALS FOR SMALL SPILLS SHALL BE USED. DO NOT WASH OR BURY THE SPILL
MATERIAL AS THIS ONLY RESULTS IN ADDITIONAL REMEDIATION REQUIREMENTS. REMOVE THE
CONTAMINATED ABSORBENT MATERIALS PROMPTLY AND DISPOSE OF PROPERLY ACCORDING TO
LOCAL AND STATE LAWS.
AVOID FUEUNG OF CONSTRUCTION EQUIPMENT AT VARIOUS LOCATIONS AROUND THE SITE.
TRANSPORT THE VEHICLE OR EQUIPMENT TO DESIGNATED ONSITE FUELING AREAS WHERE
ADEQUATE PREVENTION AND SPILL CONTAINMENT MATERIALS ARE LOCATED.
EMPLOYEES AND SUBCONTRACTORS SHOULD BE TRAINED IN PROPER FUEUNG AND CLEANUP
PROCEDURES.
DEDICATED FUELING AREAS SHOULD BE PROTECTED FROM STORMWATER INFILTRATION AND
RUNOFF, AND SHODU) BE LOCATED AT LEAST 50 FT AWAY FROM DOWNSTREAM DRAINAGE
FACILITIES, WATERWAYS, AND FLOOD PLAINS. FUELING MUST BE PERFORMED IN A LEVEL AREA.
PROTECT FUEUNG AREAS WITH BERMS OR DIKES TO PREVENT INFILTRATION, RUNOFF, AND TO
CONTAIN SPILLS.
NOZZLES USED IN VEHICLE AND EQUIPMENT FUELING SHOULD BE EQUIPPED WITH AN AUTOMATIC
SHUTOFF TO CONTROL SPILLS AND DRIPS. FUELING OPERATIONS SHOULD BE MONITORED BY THE
FUELING OPERATOR AT ALL TIMES.
FEDERAL, STATE, AND LOCAL REQUIREMENTS SHOULD BE OBSERVED FOR ANY TEMPORARY ABOVE
GROUND STORAGE TANKS.
COLLECTION STORAGE. AND DISPOSAL OF MATERIALS
LITTERING ON THE PROJECT SITE IS PROHIBITED.
TO PREVENT CLOGGING OF THE STORM DRAINAGE SYSTEM LITTER AND DEBRIS SHOULD BE
REMOVED FROM DRAINAGE GRATES, TRASH RACKS, AND DITCHES DAILY.
TRASH RECEPTACLES SHOULD BE PROVIDED IN THE CONSTRUCTION STAGING AREAS, FIELD
TRAILER AREAS, AND AREAS UTIUZED FOR LUNCH AND BREAK PERIODS.
DOMESTIC TRASH FROM WORK AREAS WITHIN THE CONSTRUCTION UMITS OF THE SITE SHOULD
BE COLLECTED AND PLACED IN WATERTIGHT DUMPSTERS WEEKLY AT A MINIMUM. DOMESTIC
TRASH SHOULD BE COLLECTED FROM THE SITE REGARDLESS OF THE SOURCE. COLLECTED
UTTER AND DEBRIS SHOULD NOT BE PLACED IN OR NEXT TO THE STORMWATER DRAINAGE
SYSTEMS OR WATERWAYS.
DUMPSTERS OF SUFFICIENT SIZE AND QUANTITY SHOULD BE PROVIDED TO CONTAIN THE SOUD
WASTE GENERATED BY THE PROJECT.
DUMPSTERS SHOULD BE REMOVED FROM THE PROJECT SITE ONCE THEY BECOME FULL AND
THE CONTENTS DISPOSED OF BY THE TRASH HAULING CONTRACTOR.
CONSTRUCTION DEBRIS AND WASTE SHOULD BE REMOVED FROM THE SITE WEEKLY OR MORE
FREQUENTLY AS REQUIRED. THE CONTRACTOR SHOULD USE THEIR BEST JUDGEMENT IN
ANTICIPATING WHEN A DUMPSTER WILL BE FULL AND SCHEDULE A PICKUP IN ADVANCE OF
THE DUMPSTER BEING FULL TO PREVENT OVER TOPPING OF THE DUMPSTER OR PLACEMENT
OF EXCESS MATERIAL ON THE GROUND.
CONSTRUCTION MATERIAL VISIBLE TO THE PUBLIC SHOULD BE STORED OR STACKED IN AN
ORDERLY MANNER AWAY FROM THE STORM DRAINAGE SYSTEM, WATERWAYS, AND FLOOD PLAIN.
STORMWATER RUNOFF SHOULD BE DIVERTED FROM STORED SOLID WASTE THROUGH THE USE
OF BERMS, DIKES, OR OTHER TEMPORARY DIVERSION STRUCTURES OR THROUGH THE USE OF
MEASURES TO ELEVATE THE WASTE COLLECTION DUMPSTER.
SOUD WASTE STORAGE AREAS SHOULD NOT BE LOCATED IN AREAS PRONE TO FLOODING OR
PONDING AND SHOULD BE LOCATED AT LEAST 50 FT FROM STORM DRAINAGE SYSTEMS AND
WATERWAYS.
INSPECTION AND MAINTENANCE
INSPECT AND VERIFY THAT ACTMN -BASED PRACTICES ARE IN PLACE PRIOR TO THE START OF
CONSTRUCTION IN THAT AREA. INSPECT EACH PRACTICE WEEKLY TO VERIFY IMPLEMENTATION.
INSPECT CONSTRUCTION WASTE COLLECTION AREA REGULARLY TO INSURE ALL WASTE MATERIALS
ARE BEING DISPOSED OF PROPERLY.
ARRANGE FOR REGULAR WASTE COLLECTION WITH A TRASH HAUUNG CONTRACTOR.
NRY WASHY AR
THE FOLLOWING STEPS WILL HELP REDUCE STORMWATER POLLUTION FROM CONCRETE AND
MASONRY WASTES: DISCUSS THE CONCRETE MANAGEMENT TECHNIQUES DESCRIBED, SUCH AS
HANDLING OF CONCRETE WASTE AND WASHOUT AREAS WITH THE READY -MIX CONCRETE
SUPPUER BEFORE ANY DEUVERIES ARE MADE. DISCUSS MASONRY WASTE MANAGEMENT
TECHNIQUES WITH THE MASONRY CONTRACTORS FOR THE CONTROL OF CEMENT MIXER
WASHOUT AREAS.
INCORPORATE REQUIREMENTS FOR CONCRETE AND MASONRY WASTE MANAGEMENT INTO
MATERIAL SUPPUER AND SUBCONTRACTOR AGREEMENTS.
STORE DRY AND UQUID MATERIALS IN A COVERED AREA AWAY FROM DRAINAGE AREAS.
PREVENT MASONRY SAND STOCKPILE FROM WASHING INTO STREETS, STORM DRAINAGE
SYSTEMS, AND WATERWAYS.
AVOID MIXING EXCESS AMOUNTS OF FRESH CONCRETE OR MORTAR.
PERFORM WASHOUT OF CONCRETE TRUCKS OFFSITE OR IN DESIGNATED AREAS ONLY.
PERFORM MORTAR MIXER WASHOUT IN ONE DESIGNATED AREA FOR THE DURATION OF THE
PROJECT.
DO NOT WASH OUT CONCRETE TRUCKS OR MORTAR MIXERS INTO STORM DRAINS, OPEN
DITCHES, STREETS, OR WATERWAYS.
DO NOT ALLOW EXCESS CONCRETE OR MORTAR TO BE DUMPED ONSITE, EXCEPT IN
DESIGNATED AREAS.
FOR ONSITE WASHOUT AREAS:
- LOCATE WASHOUT AREA AT LEAST 50 FEET FROM STORM DRAINS, OPEN DITCHES, OR
WATERWAYS.
-DO NOT ALLOW RUNOFF TO LEAVE THE DESIGNATED AREA BY CONSTRUCTING A TEMPORARY
PIT OR BERMED AREA LARGE ENOUGH FOR UQUID AND SOLID WASTE.
-WASH OUT WASTES INTO THE TEMPORARY PIT WHERE THE CONCRETE CAN SET, BE BROKEN
UP, AND BE DISPOSED OF PROPERLY.
-AVOID CREATING UNNECESSARY RUNOFF BY DRAINING WATER FROM THE WASHOUT AREA INTO
A BERMED, LEVEL AREA WHEN WASHING CONCRETE TO REMOVE FINE PARTICLES AND EXPOSE
THE AGGREGATE.
-DO NOT WASH SWEEPINGS FROM EXPOSED AGGREGATE CONCRETE INTO THE STREET OR
STORM DRAIN SYSTEM. COLLECT AND RETURN SWEEPINGS TO AGGREGATE BASE STOCKPILE OR
DISPOSE OF PROPERLY.
