[ARCHIVED] Reduce Dust When Planting Winter Ryegrass

Overseeding News Release

PHOENIX (September 14, 2021) — The Maricopa County Air Quality Department (MCAQD) encourages commercial properties, government agencies, and residents to take dust reduction measures when planting winter ryegrass this fall. Scalping existing Bermuda grass during overseeding can impact air quality by generating dust. Each year the department responds to questions and concerns from landscapers, golf course managers, and residents regarding the dust created during the overseeding process. 

 

The department offers the following tips to help prevent dust during the overseeding process:

 

  • Avoid scalping on windy days and on High Pollution Advisory days. 
  • Don’t over-dry the area prior to scalping. 
  • Apply water to moisten the area prior to scalping. 
  • Reduce the area to be overseeded and the depth of scalping.       
  • Keep dust collection screens and filters in good working condition. 
  • Sweep loose debris from paved surfaces instead of using a leaf blower, see the P-25 Ordinance.
  • Moisten material piles before loading into dumpsters. 

 

Generally, overseeding/scalping projects do not require a dust control permit. However, the dust emissions generated during these projects are still regulated under MCAQD’s Rule 310. Visible dust emissions beyond the property line may result in an air quality violation.      

 

Residents may report air quality concerns or dust control issues by calling the department at 602-372-2703 or filing a report online at Maricopa.gov/2132.
