Dust Control — Arizona
Jenterra applies plant-based, non-chloride dust suppressants to disturbed soil, haul roads and unpaved lots across Arizona, and builds the trackout controls that keep sites compliant with Maricopa County Rule 310 and equivalent county requirements. Suppressants are manufacturer-formulated for bind and reapplication interval — we apply to spec, not by eye.
Why chloride-based control isn't the default here
Arizona's dust rules exist because PM10 is a real regional air-quality problem, and enforcement is active — Maricopa County's Rule 310 governs dust from earthmoving, disturbed surfaces and unpaved haul roads, with dust control plans and stabilized entrances required on most active sites. We apply plant-based, non-chloride suppressants because they bind fines at the surface without the corrosion, vegetation damage and runoff concerns that come with chloride products, and because manufacturers of the products we use publish application rates and reapplication intervals we follow rather than guess at.
What we build and apply
Dust control on an active site is a combination of suppressant application and physical controls, not one or the other.
- Plant-based suppressant application on disturbed soil, stockpiles and staging areas
- Stabilized construction entrances sized to Rule 310 requirements
- Haul road treatment for aggregate base, gravel and dirt access roads
- Trackout control and street sweeping coordination at site exits
- Reapplication scheduling tied to traffic volume and weather rather than a fixed calendar
Haul roads, lots and long-duration sites
A haul road that sees loaded trucks all day breaks down a suppressant film faster than a perimeter stockpile that's rarely disturbed, so we treat different site zones on different schedules rather than one blanket application. For long-duration lots and staging yards, we build in periodic reapplication so the site stays compliant through the full project, not just at inspection.
Wind events matter as much as traffic. Arizona's spring wind season and pre-monsoon outflow winds can strip a marginal application in one afternoon, so we watch forecasts on active accounts and get ahead of high-wind days when we can.
Documentation for inspectors
Rule 310 compliance is judged on visible dust and on paperwork — dust control plans, application logs and stabilized-entrance maintenance records. We keep application dates, products and rates documented so that record is ready if a county inspector shows up.
Frequently asked questions
- Are your dust suppressants safe near vegetation and drainage?
- We use plant-based, non-chloride suppressant products, applied per the manufacturer's rate, specifically to avoid the vegetation damage and salt loading associated with chloride-based dust control near landscaping and drainage features.
- Do you handle Rule 310 dust control plans?
- We install and maintain the physical controls and suppressant application a dust control plan requires and coordinate with the plan preparer or site's compliance contact. We recommend confirming plan-specific requirements with Maricopa County or the applicable county agency.
- How often does a haul road need to be re-treated?
- It depends on traffic volume, product used and weather — a heavily trafficked haul road may need reapplication far sooner than a lightly used access road. We set a schedule based on observed wear rather than a single fixed interval.
