NPDES WHEN ONE ACRE OR MORE IS BEING DISTURBED
1. CONSTRUCTION SITE BEST MANAGEMENT PRACTICES (BMPS) FOR THE MANAGEMENT OF STORM
WATER AND NON- STORMWATER DISCHARGES SHALL BE DOCUMENTED ON THE GRADING PLAN
WHICH THEREBY BECOMES THE SITE STORM WATER POLLUTION PREVENTION PLAN (SWPPP).
ARRANGEMENTS SHALL BE MADE BY THE DEVELOPER TO RETAIN THE SWPPP ON THE JOBSITE
THROUGHOUT THE TIME OF CONSTRUCTION. THE IMPLEMENTATION AND MAINTENANCE OF SITE
BMPS IS REQUIRED TO MINIMIZE JOBSITE EROSION AND SEDIMENTATION. CERTAIN BMPS MAY
BE REQUIRED TO REMAIN IN PLACE THROUGHOUT THE YEAR TO MINIMIZE EROSION AND
SEDIMENTATION. ARRANGEMENTS SHALL BE MADE BY THE DEVELOPER TO MAINTAIN THOSE
BMPS THROUGHOUT THE TIME OF CONSTRUCTION.
2. EROSION CONTROL BMPS SHALL BE IMPLEMENTED AND MAINTAINED TO MINIMIZE THE
ENTERTAINMENT OF SOIL IN RUNOFF FROM DISTURBED SOIL AREAS ON CONSTRUCTION SITES.
3. SEDIMENT CONTROL BMPS SHALL BE IMPLEMENTED AND MAINTAINED TO MINIMIZE THE
TRANSPORT OF SOIL FROM THE CONSTRUCTION SITE.
4. GRADING SHALL BE PHASED TO LIMIT THE AMOUNT OF DISTURBED AREAS EXPOSED TO THE
EXTENT FEASIBLE.
5. AREAS THAT ARE CLEARED AND GRADED SHALL BE LIMITED TO ONLY THE PORTION OF THE
SITE THAT IS NECESSARY FOR CONSTRUCTION. THE CONSTRUCTION SITE SHALL BE MANAGED
TO MINIMIZE THE EXPOSURE TIME OF DISTURBED SOIL AREAS THROUGH PHASING AND
SCHEDULING OF GRADING AND THE USE OF TEMPORARY OR PERMANENT SOIL STABILIZATION.
6. ONCE DISTURBED, SLOPES (TEMPORARY OR PERMANENT) SHALL BE STABILIZED IF THEY WILL
NOT BE WORKED WITHIN 21 DAYS. DURING THE STORM SEASON, ALL SLOPES SHALL BE
STABILIZED PRIOR TO A PREDICTED STORM EVENT. CONSTRUCTION SITES SHALL BE
REVEGETATED AS EARLY AS FEASIBLE AFTER SOIL DISTURBANCE.
7. STOCKPILES OF SOIL SHALL BE PROPERLY CONTAINED TO ELIMINATE OR REDUCE SEDIMENT
TRANSPORT FROM THE SITE TO STREETS, DRAINAGE FACILITIES OR ADJACENT PROPERTIES VIA
RUNOFF, VEHICLE TRACKING OR WIND.
8. CONSTRUCTION SITES SHALL BE MAINTAINED IN SUCH A CONDITION THAT A STORM DOES NOT
CARRY WASTES OR POLLUTANTS OFF THE SITE. DISCHARGES OTHER THAN STORMWATER
(NON - STORMWATER DISCHARGES) ARE PROHIBITED, EXCEPT AS AUTHORIZED BY AN INDIVIDUAL
NPDES PERMIT, THE STATEWIDE GENERAL PERMIT - CONSTRUCTION ACTIVITY. POTENTIAL
POLLUTANTS INCLUDE BUT ARE NOT LIMITED TO: SOLID OR LIQUID CHEMICAL SPILLS; WASTES
FROM PAINTS, STAINS, SEALANTS, SOLVENTS, DETERGENTS, GLUES, LIME, PESTICIDES,
GERVICIDES, FERTILIZERS, WOOD PRESERVATIVES, AND ASBESTOS FIBERS, PAINT FLAKES OR
STUCCO FRAGMENTS; FUELS, OILS LUBRICANTS, AND HYDRAULIC, RADIATOR OR BATTERY FLUIDS;
CONCRETE AND RELATED CUTTING OR CURING RESIDES; FLOATABLE WASTES, WASTES FROM
ENGINE /EQUIPMENT STEAM CLEANING OR CHEMICAL DEGREASING; WASTES FROM STREET
CLEANING, AND SUPER - CHLORINATED POTABLE WATER FROM LINE FLUSHING AND TESTING.
DURING CONSTRUCTION, DISPOSAL OF SUCH MATERIALS SHOULD OCCUR IN A SPECIFIED AND
CONTROLLED TEMPORARY AREA ON -SITE PHYSICALLY SEPARATED FROM POTENTIAL STORMWATER
RUNOFF, WITH ULTIMATE DISPOSAL IN ACCORDANCE WITH LOCAL, STATE AND FEDERAL
REQUIREMENTS.
9. RUNOFF FROM EQUIPMENT AND VEHICLE WASHING SHALL BE CONTAINED AT CONSTRUCTION
SITE AND MUST NOT BE DISCHARGED TO RECEIVING WATERS OR THE LOCAL STORM DRAIN
SYSTEM.
10. APPROPRIATE BMPS FOR CONSTRUCTION - RELATED MATERIALS, WASTES, SPILLS OR RESIDUES
SHALL BE IMPLEMENTED TO ELIMINATE OR REDUCE TRANSPORT FROM THE SITE TO STREETS,
DRAINAGE FACIUTIES, OR ADJOINING PROPERTIES BY WIND OR RUNOFF.
11. ALL CONSTRUCTION CONTRACTORS AND SUBCONTRACTORS PERSONNEL ARE TO BE MADE
AWARE OF THE REQUIRED BMPS AND GOOD HOUSEKEEPING MEASURES FOR THE PROJECT SITE
AND ANY ASSOCIATED CONSTRUCTION STAGING AREAS.
12. DISCHARGING CONTAMINATED GROUNDWATER PRODUCED BY DEWATERING GROUNDWATER THAT
HAS INFILTRATED INTO THE CONSTRUCTION SITE IS PROHIBITED. DISCHARGING OF
CONTAMINATED SOILS VIA SURFACE EROSION IS ALSO PROHIBITED. DISCHARGING
NON - CONTAMINATED GROUNDWATER PRODUCED BY DEWATERING GROUNDWATER ACTIVITIES MAY
REQUIRE A NATIONAL POLLUTANT DISCHARGE ELIMINATION SYSTEM ( NPDES) PERMIT FROM THE
REGIONAL WATER QUALITY CONTROL BOARD.
13. BMPS SHALL BE MAINTAINED AT ALL TIMES. IN ADDITION, BMPS SHALL BE INSPECTED PRIOR
TO PREDICTED STORM EVENTS AND FOLLOWING STORM EVENTS.
14. AT THE END OF EACH DAY OF CONSTRUCTION ACTIVITY, ALL CONSTRUCTION DEBRIS AND WASTE
MATERIALS SHALL BE COLLECTED AND PROPERLY DISPOSED OF IN TRASH OR RECYCLE BINS.

ROUGH GRADING ':A':• SITE PREP. & MOBILIZATION
GENERAL REQUIREMENTS
1. PRE - WATERING SHALL COMMENCE AT LEAST THREE (3) DAYS PRIOR TO ACTUAL
GRADING USING A TEMPORARY ON -SITE IRRIGATION SYSTEM. CONNECT70N TO
ANY EXISTING WATER SYSTEM SHALL BE DONE IN COMPLIANCE WITH C. V. W. D.
TEMPORARY WATER LINES SHALL BE INSTALLED WITH A MINIMAL DISTURBANCE
OF ANY OFF -SITE AREAS THEY PASS THROUGH.
2. WRITTEN AND NOTARIZED PERMISSION LETTERS SHALL BE SUBMITTED TO THE
COUNTY ENGINEERING DEPT. FROM ANY ADJACENT LAND OWNERS WHOSE PROPERTY
WILL BE USED IN ANY MANNER FOR CONSTRUCTION, STAGING, ACCESS, ETC.
J. PUBLIC ACCESS TO THE GRADING SITE SHALL BE RESTRICTED AS MUCH AS
POSSIBLE, TO REDUCE AND CONTROL VEHICULAR ACTIVITY, AND TO REDUCE
THE POTENTIAL FOR VANDALISM AND /OR INJURY.
4. ACTIVITY AREAS SUCH AS EQUIPMENT STORAGE AREA, MATERIALS STORAGE
AREA, TEMPORARY OFFICE TRAILERS, AND EMPLOYEE PARKING, SHOULD BE
LOCATED IF POSSIBLE ON EXISTING PAVED SURFACES, IF TRAFFIC WOULD
NOT BE AFFECTED. IN LIEU OF EXISTING PAVING, A SOIL STABILIZER THAT
DOES NOT REQUIRE CONSTANT WATERING, SUCH AS AN AGGREGATE BASE OR
GRAVEL COULD BE USED FOR INITIAL STAGING AREA.
ROUGH GRADING A" CONTINUED.
S THE TIRES OF VEHICLES BEING USED ON -SITE SHOULD BE INSPECTED AND WASHED
IF NECESSARY TO MINIMIZE TRACKING OF DIRT ONTO PUBLIC STREETS IF EXTENSIVE
EXPORT OR IMPORT OF DIRT IS TO BE DONE, A PAVED WHEEL WASHING AREA AT
LEAST 24' WIDE BY 50' LONG SHOULD BE PROVIDED AT THE EXIT, TO FACIL ?ATE
THE INSPECTION AND CLEANING OF TIRES. THE COST OF THIS PAVING SHOULD BE
WEIGHED AGAINST THE COST OF INCREASED STREET SWEEPING PROVIDED BY THE

GENERAL REQUIREMENTS
1. HAULING PROCEDURES.
ALL VEHICLES GOING FROM DIRT AREAS ONTO PAVED STREETS SHALL HAVE TIRES AND
WHEELS INSPECTED AND WASHED IF NECESSARY TO AVOID 'TRACKING -OUT" DIRT.
TRUCKS HAULING DIRT ON PAVED STREETS SHALL MAINTAIN AT LEAST A HALF FOOT
FREEBOARD" FROM RIM TO DIRT, AND COVER ALL DIRT OR DUSTY DEBRIS LOADS
WITH AN APPROPRIATE TARP.
THE HAUL ROUTE SHOULD BE SHOWN HEREON OR ON AN ATTACHED SHEET, AND
SHALL BE CLEARED WITH THE COUNTY ENGINEER FOR ANY APPLICABLE TRANSPORT
PERMITS PRIOR TO ITS USE. ALL HAULING TRUCKS SHALL HAVE A COPY OF THESE
PROVISIONS WI774 THEM AT ALL TIMES.
THE IMPORT OR EXPORT S17£ MUST HAVE A VALID GRADING PERMIT ALSO, AND SHOULD
BE COMPLYING WITH ALL APPROPRIATE DUST MITIGA77ON MEASURES ALSO.
WHEN PRACTICAL, TRUCKS AND EQUIPMENT, SHOULD SHUT OFF ENGINES RATHER THAN
IDLING FOR EXTENDED PERIODS, TO MINIMIZE EXHAUST EMISSIONS AND NOISE. THIS
BECOMES MORE CRITICAL AS THE SIZE AND NUMBERS OF VEHICLES INCREASES.
2. VEHICLES TRAVELING ON DIRT AND /OR ON UNPAVED ROADS SHOULD RESTRICT THEIR
SPEED TO 15 M.P.H. MAXIMUM. SIGNS TO THAT EFFECT SHOULD BE PLACED AT THE
PROJECT ENTRANCE OR OTHER APPROPRIATE SPOT TO IMPROVE COMPLIANCE.
J. ALL STRIPPED, GRADED OR OTHERWISE DISTURBED AREAS SHALL BE STABILIZED
BY SOME APPROPRIATE MEANS. AREAS ACTIVELY BEING GRADED CAN USUALLY BE
STABILIZED BY APPLYING LOTS OF WATER. DISTURBED AREAS NOT ACTIVELY BEING
WORKED MAY BE EFFEC77VELY TREATED WITH SOME MORE DURABLE SOIL
STABILIZER, SUCH AS HYDROMULCH, TO AVOID CONSTANT WATERING.
THE PREFERRED METHOD OF SITE WATERING IS BY SPRINKLER, IF THEY DO NOT
INTERFERE WITH THE GRADING VEHICLES.
4. IF PERIMETER BLOCK WALLS ARE TO BE BUILT THEY SHOULD BE GIVEN A HIGH
PRIORITY SINCE THEY WILL HELP TO CATCH BLOWS4ND AND COULD THEREBY
REDUCE THE AMOUNT OF STREET SWEEPING REQUIRED.

OTHERWISE STABILIZED OR COVERED TO HELP COUNTERACT THEIR HIGH PROFILE
EXPOSURE TO THE WIND.
2. ALL PREVIOUSLY ROUGH GRADED AREAS THAT WILL BE INAC77VE IN THIS PHASE
SHOULD BE TREATED WITH A DURABLE SOIL STABILIZER OR GROUND COVER SYSTEM.
IF A VEGETATED GROUND COVER IS UTILIZED IT IS ONLY NECESSARY TO GET IT
INITIALLY ESTABLISHED. THE ROOT SYSTEM AND TOP STUBBLE MAY BE SUFFICIENT
TO HOLD THE DUST EVEN IF WATERING IS DISCONTINUED.
J. FOR TRACTS, MUL77PLE PARCELS, AND EXTENSIVE COMMERCIAL SITES PAVED
ACCESS TO THE BUILDING S17ES WILL BE REQUIRED PRIOR TO FRAMING OF THE
BUILDINGS THIS CONSTRUCTION STAGE USUALLY INDICATES AN INCREASE IN THE
NUMBERS OF WORKERS AND THEIR VEHICLES. ALSO, THE PAVED ACCESS IS
RECOMMENDED FOR FIRE FIGH77NG PURPOSES. IF PAVING IS DESIRED BEFORE
ALL U77LI77ES AND /OR LA7ER4LS ARE INSTALLED, THE BASE LIFT OF ASPHALT
IS SUFFICIENT FOR ACCESS. THE A.C. CAN BE CAPPED" LATER, LEAVING A FINAL
SURFACE THAT IS FREE OF U77LITY CUTS AND PATCHES.
4. AS PAVED ACCESS IS EXTENDED, THE STAGING AREA CAN BE MOVED CLOSER
TO THE BUILDING SITES THE STORAGE AND OFFICE TRAILERS, EQUIPMENT,
AND EMPLOYEE PARKING CAN BE MOVED ONTO PAVED PORTIONS OF THE SITE.

GENERAL REQUIREMENTS
1. ALL INACTIVE AREAS SHOULD HAVE BEEN STABILIZED BY THIS STAGE. IF PREVIOUSLY
COVERED, THE ACTUAL BUILDING PADS MAY NOW NEED TO BE STRIPPED, SCARIFIED,
AND RECOMPACTED FOR BUILDING PAD COMPACTION AND ELEVATION CER77RC477ONS.
DUST WOULD BE KEPT DOWN BY WATERING, USUALLY BY TEMPORARY SPRINKLERS.
2. TRENCHING FOR BUILDING UTILITIES, DRYWELL CONSTRUCTION, POOLS, AND TENNIS
COURT CONSTRUCTION FORM THE BULK OF EARTHWORK AFTER THE PADS HAVE BEEN
CERTIFIED. TEMPORARY SPRINKLERS MAY S77LL BE USED ON THE BUILDING SITE FOR
DUST CONTROL PRIOR TO THE BEGINNING OF FRAMING.
J. ESTABLISHING THE LANDSCAPE AND SPRINKLER SYSTEM AROUND THE PERIMETER OF
LARGE PROJECTS SHOULD BE DONE AT THIS STAGE. PLAN7NGS AROUND THE
PERIMETER SERVE AS A WIND BUFFER AND COLLECTION SYSTEM FOR DUST AND SAND.
IT IS GOOD TO HAVE DUST AND SAND WELL UNDER CONTROL PRIOR TO THE BUILDING
PHASE FOR THE SAKE OF CERTAIN GLUING AND PAINTING PROCESSES THAT CAN BE
RUINED BY BLOWSAND OR DUST.

AND GROUND COVER AND /OR LANDSCAPING IS ESTABLISHED.
2. CONSTRUCTION DUST SUCH AS FROM CEMENT, PLASTER, PAINT OVERSPRAY, WOOD
CUTTING, GRINDING OPERATIONS, ETC., SHOULD BE MINIMIZED ALSO. A PERIMETER
BARRIER OF SPRINKLERS AND PLANTINGS CAN SERVE TO CATCH SOME OF THIS
POTENTIALLY HAZARDOUS MATERIAL AS WELL AS NATURAL DUST AND BLOWSAND,
CONCENTR477ONS OF CONSTRUCTION DUSTS CAN RESULT FROM WASHING OF
EQUIPMENT AND SHOULD BE PROPERLY DISPOSED OF BEFORE THEY CAN DRYOUT
AND BLOW OR BE WASHED ACROSS PROJECT BOUNDARIES.
