Rule 403 Dust Control Information

Fugitive dust is particulate matter that is suspended in the air by direct or indirect human activities. Two South Coast AQMD rules were adopted with the purpose of reducing the amount of fugitive dust entrained as a result of human activities.  Rule 403 applies to any activity capable of generating fugitive dust.  Rule 403.1 is supplemental to Rule 403 and applies only to fugitive dust sources in Coachella Valley.  Rule 403.2 is another supplemental rule to Rule 403 designed to mitigate dust from large roadway projects close to sensitive receptors throughout South Coast AQMD.



The following applies to projects not located in the Coachella Valley.  For projects in the Coachella Valley, please see the Coachella Valley Fugitive Dust Control Plan section.

Rule 403 requires the implementation of best available dust control measures (BACM) during active operations capable of generating fugitive dust. This rule also requires activities defined as “large operations” to notify the South Coast AQMD by submitting specific forms.  A large operation is defined as any active operation on property containing 50 or more acres of disturbed surface area; or any earth moving operation with a daily earth-moving or throughput volume of 3,850 cubic meters (5,000 cubic yards), three times during the most recent 365 day period. 

Large Operations must submit the following forms: 

  • Form 403N (Large Operation Notification)- must be submitted within 7 days of qualifying as a large operation.  Include a site location map. Once approved by South Coast AQMD, the notification is valid for one year.  Alternatively, you may submit a site specific Dust Plan with the associated fee.           

  • Form 403NC (Statement of No Change)- must be submitted at least 30 days prior to the expiration date of the Large Operation Notification.  The submittal of this form will represent resubmittal of a large operation notification if conditions will not change for the upcoming year.

  • Form 403C (Notice of Completion)- must be submitted within 30 days of no longer qualifying as a large operation.

Submit all forms to:


Rule 403.1 is a supplemental rule to Rule 403 and is applicable to man-made sources of fugitive dust in Coachella Valley.  The purpose of this rule is to reduce fugitive dust and resulting PM10 emissions from man-made sources in the Coachella Valley.  Rule 403.1 requires a Fugitive Dust Control Plan approved by South Coast AQMD or an authorized local government agency prior to initiating any construction/ earth-moving activity.  These requirements are only applicable to construction projects with 5,000 or more square feet of surface area disturbance.

If submitting a Dust Control Plan to South Coast AQMD: 
For projects with less than 10 acres of disturbed surfaces, submit:

1. Form 400-A (Application for Permit to Construct and Permit to Operate)

4. Site location map

6. Receipt of payment or check- please see the Filing and Evaluation Fee section below

Once approved by South Coast AQMD, the plans are valid for one year from the date of approval.  If a project will extend beyond one year and if all sources of fugitive dust and control measures are the same as in the originally approved plan, the operator can extend the plan for an additional year by submitting:
