PLEASE READ AND FILL OUT THIS DOCUMENT APPROPRIATELY. EVEN SMALL PROJECTS MUST
DO THEIR PART. PMDUST (POWDERY DUST OF 10 MICRONS OR SMALLER DIAMETER) HAS
BEEN IDENTIFIED AS X POTENTIALLY SERIOUS HEALTH THREAT. THIS FINE DUST CAN LODGE
DEEP /N THE LUNGS AND HAS BEEN ASSOCIATED WITH BRONCHITIS AND OTHER RESPIRATORY
ILLNESSES. DESERT DUST CAN BE PARTICULARLY UNHEALTHFUL, BEING ASSOCIATED WITH
DESERT LUNG SYNDROME" AND LUNG INFECTIONS CAUSED BY FUNGAL SPORES CARRIED IN
DESERT DUST CHILDREN, THE ELDERLY, AND PERSONS WITH RESPIRATORY CONDITIONS, ARE
PARTICULARLY SENSITIVE TO FINE DUST BUT EVERYONE IS ADVERSELY AFFECTED BY THE
RELATIVELY HIGH LEVELS OF Pb110 THAT OCCUR IN THE COACHELLA VALLEY. LARGER SAND
PARTICLES CAN BE TURNED INTO THIS DUST THROUGH THE GRINDING ACTION OF TIRES ON
ROADWAYS AND THROUGH REPETITIVE PLOWING AND DISKING OPERATIONS.

5. THE TIRES OF VEHICLES BEING USED ON -SITE SHOULD BE INSPECTED AND WASHED 1F
NECESSARY TO STOP TRACKING OF DIRT ONTO PUBLIC STREETS. IF EXTENSIVE EXPORT OR
IMPORT OF DIRT IS TO BE DONE, A PAVED OR GRAVELED WHEEL WASHING AREA AT LEAST 12'
WIDE BY 100' LONG SHOULD BE PROVIDED AT THE EXIT, TO FACILITATE THE INSPECTION AND
CLEANING OF TIRES. RUMBLE STRIPS" MADE FROM LUMBER, RAILROAD TRACK,OR SIMILAR
MATERIALS CAN HELP REDUCE THE MUD GETTING ONTO THE CLEANING AREA. STREET SWEEPING
AND WASHING IS STILL TYPICALLY REQUIRED, BUT MAY BE REDUCED BY PROPER USE OF A
"WHEEL WASHING AREA" LIKE THIS. THEY ARE REQUIRED ON PROJECTS OVER 5 ACRES OR WITH
OVER 5,000 CUBIC YARDS OF IMPORT OR EXPORT
6. A STANDARD SIGN WITH THE FOLLOWING INFORMATION MUST BE POSTED ON THE SITE,
AT LEAST ONE SIGN PER FRONTING STREET. THE SIGN MUST INCLUDE. THE GRADING PERMIT
NUMBER, THE PROJECT NAME, MAP NUMBER /F APPROPRIATE, THE AUTHORIZED DUST CONTROLLER
PHONE NUMBER(S), THE CITY PHONE NUMBER, AND THE SOUTH COAST AIR QUALITY MANAGEMENT
DISTRICT (SC.A.Q.M.D.) PHONE NUMBER.
7. 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
ON PROJECTS OVER 5 ACRES TO IMPROVE COMPLIANCE.
8. WHEN WIND SPEEDS EXCEED 25 MPH, BY CONTINUOUS ANEMOMETER READING, OR IN GUSTS AT
LEAST TWICE WITHIN A THIRTY MINUTE PERIOD, MEASURED ON THE SITE, VEHICULAR ACTIVITY ON

8. OTHER PRELIMINARY WORK:
PHASE "B". ROUGH GRADING (MASS GRADING OF STREETS, PADS, RET. BASINS)
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 CITY ENGINEER FOR ANY APPLICABLE TRANSPORT
PERMITS PRIOR TO ITS USE. ALL HAULING TRUCKS SHALL HAVE A COPY OF THESE
PROVISIONS WITH THEM AT ALL TIMES.
THE IMPORT OR EXPORT SITE MUST HAVE A VALID GRADING PERMIT AND SHOULD
BE COMPLYING WITH ALL APPROPRIATE DUST MITIGATION MEASURES.
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. ALL STRIPPED, GRADED OR OTHERWISE DISTURBED AREAS SHALL BE STABILIZED
BY SOME APPROPRIATE MEANS. AREAS ACTIVELY BEING GRADED CAN USUALLY BE
STABILIZED BY APPLYING L07S OF WATER. DISTURBED AREAS NOT ACTIVELY BEING
WORKED MAY BE EFFECTIVELY TREATED WITH SOME MORE DURABLE SOIL STABILIZER,
SUCH AS HYDROMULCH, TO AVOID CONSTANT WATERING. THE PREFERRED METHOD OF
SITE WATERING IS BY SPRINKLER, ESPECIALLY AROUND THE PERIMETER. SPRINKLERS MUST
BE SET TO RUN ON WEEKENDS AND EVENINGS WHEN WATER TRUCK DRIVERS ARE NOT
AVAILABLE. A TYPICAL WATER TRUCK CAN ONLY HANDLE WELL ABOUT 4 ACRES PER HOUR.

MUST BE CLEARED WITH THE CITY AND REGIONAL WATER QUALITY CONTROL BOARD.
PHASE "D'.• FINISH GRADING (LANDSCAPING)
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 CERTIFICATIONS.
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 STILL BE USED ON THE BUILDING SITE FOR
DUST CONTROL PRIOR TO THE BEGINNING OF FRAMING. TREATMENT WITH A BIODEGRADABLE
OIL" APPROVED FOR DUST CONTROL IS RECOMMENDED WHERE IT /S DIFFICULT TO WATER.
J. ESTABLISHING THE LANDSCAPE AND SPRINKLER SYSTEM AROUND THE PERIMETER OF
LARGE PROJECTS SHOULD BE DONE AT THIS STAGE. PLANTINGS AROUND THE
PERIMETER SERVE AS A WIND BUFFER AND COLLECTION SYSTEM FOR DUST AND SAND.
IT /S 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
4. DISTURBED AREAS AROUND BUILDINGS SHOULD BE WATERED BY HAND FOR DUST
CONTROL UNTIL SUCH TIME THAT THE SPRINKLER SYSTEM IS FULLY FUNCTIONAL
AND GROUND COVER ANDVOR LANDSCAPING IS ESTABLISHED. IF WATERING IS DIFFICULT
DUE TO BUILDING INTERF RENCE, CHEMICAL OR MULCH TREATMENTS ARE AVAILABLE
THAT CAN STABILIZE THE SOIL WITHOUT FREQUENT WATERING.
5. 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,
CONCENTRATIONS OF CONSTRUCTION DUSTS CAN RESULT FROM WASHING OF
EQUIPMENT AND SHOULD BE PROPERLY DISPOSED OF BEFORE THEY CAN DRY OUT
AND BLOW OR BE WASHED ACROSS PROJECT BOUNDARIES.
6. NOTE THAT SWALES SHOULD BE INSPECTED BY CITY PRIOR TO SETTING OF PERMANENT
GROUND COVER OR OTHER PLANTS.

ABATEMENT OF DUST MITIGATION FAILURE
AN IRREVOCABLE LICENSE IS HEREBY GRANTED OR CAUSED TO BE GRANTED TO PERMIT THE CITY OR
THEIR DESIGNEE TO ENTER UPON THE SITE UNDER THE FOLLOWING CIRCUMSTANCES
A. IN THE EVENT THAT WIND SPEEDS /N EXCESS OF 25 M.P.H. ARE FORECAST TO OCCUR BY
THE SOUTH COAST AIR QUALITY MANAGEMENT DISTRICT (S.C.A.Q.M.D.) FOR A PARTICULAR DAY-
B. IN THE EVENT OF AN ON -SITE ANEMOMETER THAT CONFORMS TO ALL S.C.A.Q.M.D. STANDARDS
REGISTERING 2 WIND GUSTS IN EXCESS OF 25 M.P.H. WITHIN A CONSECUTIVE 30 MINUTE
PERIOD; OR
C. IN THE EVENT FUGITIVE DUST EMISSIONS ARE VISIBLE FOR A DISTANCE OF 50 FEET FROM
ANY BOUNDARY LINE, OR
D. THE CITY IS UNABLE, BY TELEPHONE, TO ESTABLISH A PERSONAL CONTACT WITH THE
AUTHORIZED DUST CONTROLLER" AFTER A 60 MINUTE CONSECUTIVE PERIOD WHICH SHALL
START WITH THE FIRST TELEPHONE CALL, WHETHER ANSWERED OR NOT, THEN THE CITY WILL
UNDERTAKE TO INITIATE ONE OR ALL OF THE BELOW LISTED ACTIONS.
1. THE CITY WILL CAUSE THE CESSATION OF ANY ON -SITE ACTIVITY, INCLUDING BUT NOT
LIMITED TO EARTH MOVING, CONSTRUCTION, DEMOLITION OR VEHICULAR MOVEMENT AND
MANEUVERING. ANY WATER TRUCKS OR VEHICLES SERVICING SPRINKLERS WOULD CONTINUE.
2. IN THE EVENT THAT AN ON -SITE IRRIGATION SYSTEM IS NOT INSTALLED AND/OR OPERATIONAL,
THE CITY WILL CAUSE THE SITE TO BE WATERED OR TREATED WITH DUST CONTROL CHEMICALS.
THE DUST CONTROL SECURITY WILL BE UTILIZED FIRST TO COVER ANY COSTS INCURRED.
IF COSTS EXCEED ANY DUST CONTROL SECURITY REMAINING, ADDITIONAL COSTS MAY BE ASSESSED
AGAINST THE OWNER OF THE PROJECT.
J. IN THE EVENT AN ON -SITE IRRIGATION SYSTEM /S INSTALLED, BUT ITS CONTROL CLOCK HAS NOT
TURNED THE SYSTEM ON WHEN NEEDED, THE CITY MAY TAKE ALL NECESSARY STEPS TO TURN ON
THE SYSTEM. IF IT IS INACCESSIBLE BEHIND LOCKED GATES OR LOCKED CONTROL BOXES, AND THE
CITY CAN NOT FIND THE APPROPRIATE KEYS, THE CITY MAY CUT OR BREAK LOCKS AS NECESSARY.
E. IF, IN THE OPINION OF THE CITY ENGINEER OR HIS DESIGNEE, THE INTENSITY, FREQUENCY OR
DURATION OF FUGITIVE DUST EMISSIONS FROM THE SITE CONSTITUTES A HAZARD TO THE SAFETY OF
THE PUBLIC, BY INTRUSION BEYOND THE PROJECT BOUNDARY, THE CITY ENGINEER OR HIS DESIGNEE OR
AGENT MAY IMMEDIATELY ENTER UPON THE SITE OR IMMEDIATELY TAKE OTHER SUCH ACTION AS MAY BE
NECESSARY TO REMEDY THE HAZARD, SUCH AS, BUT NOT LIMITED TO COMMENCING WATERING ON THE SITE
OR ORDERING THE CESSATION OF ANY EMISSION -GENERATING ACTIVITY OCCURRING ON -SITE
F. ANY OF THE ABOVE ACTIONS MAY BE CONSTRUED AS AN ABATEMENT FOR WHICH THE CITY
WILL "BACK CHARGE" THE GENERAL CONTRACTOR, DEVELOPER, AND/OR THE OWNER
