Rule 403 Dust Control Information

Fugitive dust is particulate matter that is suspended in the air by direct or indirect human activities. Two SCAQMD 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. 

 

SOUTH COAST AIR BASIN LARGE OPERATION NOTIFICATIONS

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 SCAQMD 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 SCAQMD, 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.



COACHELLA VALLEY FUGITIVE DUST CONTROL PLANS 

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 SCAQMD 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 SCAQMD: 
For projects with less than 10 acres of disturbed surfaces, submit:

1. Form 400-A (Application for Permit to Construct and Permit to Operate)
2. Form OD (Ownership Designee)
3. Form A (Fugitive Dust Control Plan Application)
4. Site location map
5. Form DCP (Fugitive Dust Control Plan)

For projects with 10 or more acres of disturbed surfaces, submit:

2. Form OD (Ownership Designee)
3. Form A (Fugitive Dust Control Plan Application)
4. Site location map

Submit a check for the Dust Plan filing and evaluation fee of $311.60.  The current fee is valid for the 2018-2019 fiscal year.  Fees may change on July 1st, 2019.  For more information on Plan Fees, refer to Rule 306.

Once approved by SCAQMD, 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:

 

Projects under an authorized local government agency dust control ordinance: 
If the project is subject to an authorized local government agency dust control ordinance, submit necessary paperwork to the city or County of Riverside.  Once plans are approved, submit 2 copies of the approved dust plan to SCAQMD within 10 days of approval.   

A notification must be made to the authorized local government agency or SCAQMD for projects 10 acres or more, at least 24 hours prior to initiating earth moving activities by submitting: 

  • Form PI (Project Initiation Form)

A notification must be made within 10 days of establishment of final elevations or at the conclusion of the finished grading inspection for projects 10 acres or more, whichever is first, by submitting:
