I there is a scene that epitomizes the West in early
movies and song, it is that o the dusty trail. Cattle
drives and wagon trains are accompanied by
prevalent, pervasive dust. I there is anything that
can be readily created in the West, it is dust.
Today, dust (also known as particulate matter)
is an unwelcome and unhealthy eature o poor
stewardship o our lands. While dust rom disturbed
lands is predictable, it is also preventable.
The Maricopa County Air Quality Departments
(department) Rule 310Fugitive Dust rom Dust-Generating Operations is a comprehensive set o
regulations that, when properly implemented, will
dramatically reduce dust emissions and improve
air quality. The need or improved air quality or
particulates is urgently important in Maricopa
County.
While air quality is oten good to excellent, the
number o days that do not meet or approach the
particulate air quality standard established by the
United States Environmental Protection Agency
(EPA) are ar too many and leave the region in non-
attainment. The result o unhealthul air quality
on ar too many days is the imposition o stringent
controls designed to curtail and control emissions.
Rule 310 is a critical element in Maricopa Countys
strategy to achieve improved air quality, and broad
compliance with the Rules provisions is essential.
The department has instituted an aggressive
program to monitor compliance with the Rule,
and strict enorcement is leading to reduced dust
emissions.
Every approach to improving air quality comes with
a learning curve. Rule 310 imposes requirements
and opportunities or interpretation under avariety o scenarios. In developing this handbook,
the department has reached out to those most
aected and asked or and received their input. The
intent o this handbook is to crat a practical guide
oering a comprehensive overview o how the Rule
310 is interpreted that will be useul and useda
document that will become dog-eared and tattered
through requent reerence.

The PM-10 nonattainment area includes a
substantial portion o Maricopa County that
includes most o the metropolitan Phoenix area.
This area has been deemed a nonattainment
area or air quality by the EPA and the Arizona
Department o Environmental Quality (ADEQ).The PM-10 nonattainment area exceeds the
acceptable national standard or PM-10 pollution
levels. PM-10 (particulate matter 10 microns, or
smaller, in diameter) includes dust, soot, and other
tiny bits o solid material that are released into
and move around in the air. PM-10 is produced by
many sources, including exhaust rom cars, trucks,
buses, and planes; industrial sources like power
plants; ugitive dust sources like construction,
mining, and agricultural activities; as well as uel
combustion like the operation o replaces and
wood stoves.
Area A diers rom the PM-10 nonattainment area.
Within Area A, clean-burning gasoline measures
(emissions testing; summer and winter uel
ormulations) are applicable. The boundary has
been used by many other state statues, rules, and
PM-10 Nonattainment Area
PM-10 Nonattainment Area Map showing Area A
ordinances (such as residential wood-burning) as the
area o applicability or those respective regulations.
Coverage of Rule 310
Although Indian communities are ound within the
borders o Maricopa County, the department has no
jurisdiction over them, because they are considered
sovereign nations.
This handbook does not apply to developments in Pinal
County.
Additionally, normal agricultural practices are under
the jurisdiction o ADEQ, not Maricopa County.
Construction activities on agricultural land are subject
to Rule 310.
Rule 310 applies to all o Maricopa County regardless
o whether a site is located in the PM-10 nonattainment
area or Area A (two related but distinct designations).

The purpose o this handbook is to provide a practical
guide oering a comprehensive overview o the
departments policies and interpretations o Rule 310.
The intent is that this guide will be useul and used.
The handbook is organized to respond to topical
questions and it is structured to provide answers to themost commonly encountered compliance challenges.
The department has also produced the Dust Abatement
Field Guide for the Construction Industry, a pocket-sized,
quick reerence designed to provide inormation about
how to comply with Rule 310 in the eld. While not
as comprehensive as this handbook, the Field Guide
is a durable, reliable, and brie summary o the most
important points that designated site representatives
and workers in the eld should know about Rule 310.

This Dust Abatement Handbookand the related FieldGuide are provided to assist in better understanding
the provisions o Maricopa County Air Quality
Departments Rule 310Fugitive Dust From Dust-
Generating Operations. The contents o this handbook
and the Field Guide should not be viewed as the
denitive statement o the Rule and how to achieve
compliance. Where the clear language o Rule 310 and
any ormally issued policy related to Rule 310 conicts
with this handbook or the Field Guide, Rule 310 and the

This handbook and the related eld guide were developed in 2009 in a collaborative eort between the regulated community
and the Maricopa County Air Quality Department. The basic document was developed by an internal working group within the
Department and review and comment was provided by an external working group. The external working group was comprised
o members o the regulated community who will rely on the contents o this handbook and eld guide to improve compliance
with Rule 310. Additional support was provided by Logan Simpson Design, Inc., working under contract with the department.

Why Rule 310?
Because air quality in the greatermetropolitan Phoenix area does notmeet air quality standards or PM-10, it
is necessary to a have a comprehensiveprogram to control PM-10 air pollution.Maricopa Countys Rule 310 - FugitiveDust rom Dust-Generating Operations,was developed to provide part o thiscomprehensive program.
Coverage of Rule 310
Rule 310 is a county-wide rule andcan be enorced in any portion oMaricopa County. Rule 310 also appliesregardless o whether a site is located
in the PM-10 Nonattainment Areaor Area A (two related but distinctdesignations).
Rule 310 applies to any constructionactivity that results in soil disturbance.While a ew activities are exempt,a good rule o thumb is to assumethat the activity you are planning iscovered by Rule 310 until you conrmotherwise.
The ollowing activities are denitelycovered: Land clearing using
mechanized equipment, earthmoving,weed abatement by discing or blading,excavation, construction, demolition,bulk material handling, storageand or transporation operations,operating outdoor equipment, usingstaging areas, parking areas, haul
and access roads, disturbing suraceareas associated with a project siteand installing initial landscapingor landscape maintenance usingmechanized equipment.
Rule 316 - Nonmetallic MineralProcessing is another rule thatapplies a separate set o dust controlrequirements on specic activities.Although many eatures are similar,there are distinct dierences.
Whats Not Covered?
Although tribal communities are oundwithin the borders o Maricopa County,the department has no jurisdictionover them because they are legally
considered sovereign nations. Note:check with tribal governments assome have their own dust controlrequirements.
This handbook does not apply todevelopments in Pinal County.Additionally, normal agriculturalpractices are under the jurisdictiono the Arizona Department oEnvironmental Quality (ADEQ), notMaricopa County.
Does Rule 310 Apply?
I you are engaged in a dust-generatingactivity covered by Rule 310, the rulerequirements apply at all times (24/7).Even if you do not need to have a permit,
the dust control provisions of Rule 310
still apply to your project.
Is a Permit Required?
The threshold or a permit is based onthe amount o surace area disturbedby a project. I the area disturbed will
meet or exceed 0.1 acre (4,356 squareeet) then a permit is required.
Construction activities thattake place on agricultural landsare subject to Rule 310. Forexample, construction o a newood processing warehouse
on armland would be coveredand a permit required i thesurace area disturbed metor exceeded 0.1 acre. Also,trackout originating romagricultural lands is coveredunder Rule 310 and is subjectto enorcement.
Getting Started
Helpful HintI in doubt, ask us. Departmentsta are available to answer yourquestions and a good place tostart is to contact the Desk DutySupervisor at (602) 506-6734.
A tenth o an acre is a relativelysmall amount o land. Mostcustom home residentialprojects will easily all underthe criteria to have a permit.
The opacity o dust emissionsrom dust-generatingoperations, as pictured at let,cannot exceed 20%.

create dust.
3 Dont start a project that disturbsgreater than or equal to 0.1 acreuntil you have obtained a dustcontrol permit. Include paths, oottrac areas, and all other areasthat are anticipated to result in soildisturbance, in your calculations todetermine the size o the project.
3 Plan ahead to ensure you receive yourdust control permit beore you start

is deemed complete. Also, actor intime or postal delivery o the permit.
3 As part o the permit applicationprocess, you will be required to llout an application which includesthe Dust Control Plan. The approvedpermit and the plan must be on sitebeore you start work.
3 Read and understand yourapproved Dust Control Plan. Duringpreconstruction meetings inorm allproject workers o Dust Control Planrequirements and ensure a successulproject start-up.
3 Request a courtesy inspection by anair quality inspector or their presenceat the preconstruction meeting toanswer questions. One courtesyinspection is allowed or eachproject phase (generally, these aredemolition, land development, andvertical construction).
3 Familiarize yoursel with Rule 310 andthis handbook. The Rule containsimportant details and requirementsthat may not be addressed in thehandbook. Develop a working
knowledge o the dust controlrequirements and related challenges.
3 I your project is 1 acre or larger in
size, your application must identiythe soil texture ound at the site. Thesoil texture is generally ound in asoils report prepared or the projectsite (alternatively, Appendix F o the
departments rules and regulationscontains a map o soil descriptions).

From the departments perspective, the approved Dust Control Plan is a
contract between the permit holder and the departmentits terms areenorceable, even against subcontractors working on a site. The measures
included in the Dust Control Plan are the measures that inspectors will expectyou to apply to your site.
Primary controls listed in the plan are to be used rst. Contingency measuresare to be used when the primary controls are not efectively controlling dustemissions.
I primary controls or contingency measures dont result in efective
control, the approved Dust Control Plan must be revised. The obligation isclearly on the permit holder to control dust emissions. I emissions cannot
be adequately controlled using all available measures, the project will be inviolation o Rule 310 and subject to enorcement by the department.

3-1 March 2010
What Training is
Required?
Rule 310 requires certain personnel at
a permitted site to receive training ondust control and emission reduction
strategies. The level o required
training and which personnel must
be trained depends on the amount o
acreage disturbed within the permitted
area. The table below shows who must
be trained and the level o training
required by size o the disturbed area.
Who Can Provide Training?
The department has established an
approved training program to certiyindividuals who have successully
completed required training. Training
must be given by a trainer who has
been approved by the department.
A list o approved trainers is available
on the departments website at
www.maricopa.gov/aq/divisions/
compliance/dust/dust_control_
training/deault.aspx.
Trainer ProgramInterested in becoming a trainer?
Contact the department or inormation
on the process.
Certifcations
There are two levels o certication:
basic and comprehensive.
Basic CertifcationTo earn basic certication, individualsmust complete the three-hour training
course. As indicated in the table,
water truck and water haul drivers are
required to earn basic certication.
On projects that disturb more than 1.0
acre, the permit holder must designate
a site representative who has earned
basic certication.
In addition, a Dust Control Block Permit
holder is required to have at least one
individual who has received the basicdust training certication on those sites
on which there is greater than one acre
o surace disturbance.
Employees required to have the basic
dust training must renew their training
certication once every three years.

Coordinator who has the level o
training required based on the area
disturbed by the project (see table on
page 3-1). I a site representative or
Dust Control Coordinator is required
based on the size o the project, he or
she must be given the authority to act
to control dust by the permit holder.
This means the site representative or
Dust Control Coordinator must be able
to direct actions within an area coveredby a permit to ensure compliance
with Rule 310including ceasing
operations, i necessary, to ensure that
dust is not generated.

Project Information Signs (Rule 310 308)
Information to Include
For sites permitted at ve acres or more,
the project inormation sign must
contain the inormation shown below
(using text size o at least our inches)and be placed at the main entrance o
the site:
3 project name.
3 permit holders name.
3 current dust control permit number.
3 name and local phone number o
person(s) responsible or dust control.
In addition, your sign must include the
ollowing text:
Dust Complaints?Call Maricopa County Air Quality
Department
(602) 372-2703
Should the ocial complaint phone
number ever change, the department
will send a notice to all permit holders
providing the new number.
When to Update the Sign
You must change your project
inormation sign to refect changes to
the dust control permit or Dust Control
Plan, such as:
3 a new contact name or phone
number.
3 a change in the project name.
3 a new permit number.
Where to Post the Sign
The main entrance to a site is that
which would normally be used by
employees and subcontractors when
gaining site access. As a projectmatures, an additional entrance may be
established.
The purpose o the signage
requirement is to provide the
public with inormation about the
permit status o the project, and the
sign should be posted where that
inormation is most prominently
observed by members o the public.
The project sign requirement is based
on the original acreage permitted. A
sign is still required even i a project isreduced to under ve acres.

Dust Abatement Handbook-Section 4 Permit Signage and Recordkeeping
4-2 March
What Records are
Required?
3 The dust control permit and all
updates (must be on site).
3 The Dust Control Plan and all updates
(must be on site).
3 Dust control logs documenting dust
control measures used each day (must
be available within 48 hours).
Each day a self-inspecon by the
permit holder must be conducted
with notes taken to document
observaons. This is an importantdocument and can be used to
show that site condions have
been carefully controlled. Crical
informaon that is required by
Rule 310 includes:
3 observations o damp and crusted
soil.
3 trackout conditions and actions taken
to clean up trackout.
3 daily water usage (note how water is
applied, how oten, and the amount -
a rough approximation is acceptable).
3 dust suppressant application.
3 when street sweeping occurred.
3maintenance o trackout controls
(what kind and when installed).
3 what kind and when contingency
measures in the Dust Control Plan
were used.
3 what subcontractors were on site,
include registration numbers.
3 a list o employees who have
completed dust control training,
the date o the class, and the name
o the company or person who did
the training. Keep copies o training
certicates on le.
3 all supporting documentation (e.g.,
street sweeping or water truck
receipts).
3 types and results o all test methods
conducted.
Document Retention
Records must be retained consistent
with the following meframes and
whichever is longer will apply:
3 two years rom the date the record
was initiated, as long as operations
are ongoing. For example, a ve-year
project only needs a two-year record
log.
3
all records must be retained orsix months ollowing termination o
site operations.
Recordkeeping
(Rule 310 502)
Helpful Hints3While no exact ormat is prescribed or recordkeeping, a three-ring binder is recommended or paperrecords.
3 Electronic recordkeeping, used by some permit holders, is a valid orm o recordkeeping.
3 A scanned copy o the Dust Control Permit accessible on a computer is an acceptable way to maintain an
on site copy.

Dust Abatement Handbook-Section 5 Accessible Areas
5-1 March 2010
Areas that are Accessible to the Public
The denition o areas accessible to
the public is any paved parking lot
or paved roadway that can be entered
or used or public travel primarily
or purposes unrelated to the dust
generating operation. To determinewhether an area meets this denition,
consider the ollowing:
3 any paved area with local non-
construction trac is considered
accessible to the public.
3 to ensure that an area is closed to
the public it must be clearly posted
(i.e., by using a sign that states
Construction Trac Only). Any
place on a site where the area under
construction and the area open to the
public is indistinct will be considered
an area accessible to the public.
sidewalks are considered paved areas
accessible to the public, unless they
are barricaded or marked of with
signage. Trackout on sidewalks will
not be included in the cumulative
distance trackout calculation;however, trackout on sidewalks
must be removed by the end o the
workday.
3 parking lots, including those in
strip malls and churches, are always
considered areas accessible to the
public unless marked otherwise with
signage to restrict public access.
The use o signs/barricades/ropes/
ences can help to dene a controlled
area. While the use o yellow ropeor tape to separate the area is notrequired, it has practical value in
ensuring that the area is seen to be
separate rom other areas where the
public has ready access.
Helpful HintThe public is considered to have
access to any paved area on your
site unless access is clearly and
efectively restricted. A sign and
physical restrictions (e.g., rope
barriers, cones) may be needed to
ensure that the public will avoid
an area.
Signage restricting access to paved area
Helpful HintTrackout extending rom your
project onto paved areas of site is
a common violation.
I an area is restricted and trackout
is present, it will not be cited as a
trackout violation.

6-1 March
Subcontractors
Subcontractor
Registration
Subcontractors are hired by a permit
holder to perorm various tasks on aconstruction site. The department
requires that subcontractors accessing
sites covered by a dust control permit
obtain registration. This applies to
any subcontractor engaged in dust-
generating activities (e.g., driving on
roads, landscaping, carpentry, etc.)
Registrations are good or one year
rom the date the registration is
approved/issued.
While the permit holder is responsible
or all site activities that may resultin a violation o the provisions o
Rule 310, subcontractors may, under
certain circumstances, also be held
accountable.
Displaying Subcontractor
Registration NumbersAnyone who enters an area that
is subject to a Rule 310 dust
control permit must obtain and a
subcontractor registration number
and ollow the requirements o each
projects dust control permit and Dust
Control Plan.
The subcontractor registration number
must be displayed on a jobsite. Methods o
displaying the subcontractor number may
include:
3 a sign at the project entrance.
3 painting it on a vehicle.
3 a paper sign axed to the vehicle or
equipment.
3 a magnet sign axed to the vehicle, e.g.,
on the door or bumper.
3 a rear view mirror hanger.
Subcontractors are
Subject to Enforcement
A subcontractor is required to abide by the
provisions o the dust control permit and
Rule 310 and subcontractors will be cited or
violations o Rule 310. Potential violations
may include:
3 not using a trackout control device.
3 grading when opacity exceeds 20%.
3 loading/unloading when opacity exceeds
20%.
Subcontractor registration number located on vehicle bumper
3wet utility/dry utility installation
when opacity exceeds 20%.
3 removal o barricades to avoid use
a trackout control.
3
untarped trucks exiting a site ontopaved areas accessible to the publi
3 truck reeboard limit exceeded and
spillage while crossing a public are

3 creating visible emissions beyond
property lines.
While a subcontractor will be held
responsible or their compliance
with Rule 310, the responsibility o
the permit holder and the actions o
a subcontractor can be dicult toseparate. Factors that will be taken i
account in determining which party
responsible include, but are not limit
to whether the:
3 subcontractor was inormed o the
obligations by the permit holder.
3 subcontractors actions can be clea
documented.
3 subcontractor acted in disregard o

Subcontractors (contd)
Subcontractor registration
is not required for the
following activities:
3 lunch trucks or ood vendors
3 waste management trucks
3 vendor/supplier delivery
trucks (except import, export
and stacking operations and
operations using ancillarymotorized equipment, such as
a orklit)
3 regulatory agencies
A permit holder cannot delegate primary obligations of the
permit to a subcontractor to avoid compliance responsibility.A permit holder may secure a subcontractor to perorm activities within
a permit area that are considered to be primary permit obligations. For
example, a subcontractor may be hired to install or maintain a trackout
control device. In the event that a violation occurs (or example, the trackout
control device is ound to be improperly maintained such that it is no longer
efectively controlling trackout) and the violation is due to the inaction or
untimely action o the subcontractor, the permit holder is responsible or
compliance and subject to the penalties authorized by law. The permit
holder is responsible for ensuring that onsite operations are being conductedin compliance with the permit. This obligation cannot be transferred to a
subcontractor.
Note: utilities are not considered to be subcontractors when operating under
their own block permit.
is essential to avoid the issuance o
an NOV to the permit holder. For
example, a subcontractor who has
removed a barricade to avoid going
over a trackout control device would
be issued a NOV. The inspector wouldhave to observe the violation occurring
in order to issue the NOV to the
subcontractor. In the above scenario,
i the subcontractor was not observed
and the surace was no longer stable as
a result o the subcontractors actions,
then the permit holder would be
issued a violation or unstabilized soil
(assuming the soil ailed the applicable
stability standard).
Ultimately, a permit holder is responsible
or all activity that occurs within a
permitted areaincluding activities
that are perormed by subcontractors.
While the permit holder is responsible
or the actions o subcontractors and
ensuring they conorm to department
rules when acting on their behal,
the department reserves the right to
pursue enorcement action against the
subcontractor and/or the permit holder
depending on the circumstances and
available evidence.
Helpful HintsAlthough not required by the
rule, subcontractors are encour-
aged to have their employees
complete the comprehensive
dust control training (six-hour
course).
Coordinate with the department
to schedule a dust control
presentation.
Permit holders are encouraged
to ensure that their contractual
agreements with subcontractors
include:
3 provisions or the
subcontractors to conduct theiractivities in a manner that is in
compliance with department
rules.
3 provisions that hold the
subcontractor liable or
any penalties issued by the
department that may be the
result o subcontractor activity.
Helpful HintsIt is also helpul to review the
approved Dust Control Plan, aswell as the controls that have been
established, with subcontractors
prior to starting work.
Clear communication with
subcontractors and active
monitoring o their on-site activity
can be efective methods to avoid
creating conditions that could
result in the issuance o an NOV.
A courtesy inspection could
be held in conjunction with a
meeting where subcontractors areinvited.

Dust Abatement Handbook-Section 6 Subcontractors and Block Permits
6-3 March
The purpose o the block permit is to
allow municipalities, governmental
agencies, and utilities to conduct
similar activities at multiple sites across
the county. Covered activities include
routine operation and maintenanceo urban inrastructure, as well as
the expansion or extension o that
inrastructure such as roads, utilities
(e.g., pipelines and electric substations)
and other public rights-o-way. This
category o permit can only be issued
to municipalities, governmental
agencies, and utilities. While the
permit is held by the authorized block
permit holder, subcontractors to the
authorized permit holder may operate
under the cover o the permit as would
the employees o the permit holder.The block permit will apply to those
locations that are listed in the permit
application. To conduct work at a
location not listed in the application,
the block permit holder must notiy
the department o the intent to work
in a new location at least three days
in advance o the planned activity.
The notice must include inormation
describing the location and the
anticipated start date o the work.
New construction o inrastructurethat is not an extension o an existing
system must be covered under a new
dust control permit.
Activity Occurring at
Locations Not in the Block
PermitFor any project not listed in the DustControl Block Permit application, the
applicant is required to notiy the
department at least three working days
in advance o initiating the activity.
Similarly, at new subdivisions or
commercial developments, a utility
will operate under its block permit and
is required to notiy the department
o its intention to work on a specic
property. As with other areas, a block
permit holder is required to provide
the department with noticationo its intent to operate at a location
