Reduce dust when planting winter rye grass

(PHOENIX, AZ) — Maricopa County Air Quality Department (MCADQ) encourages commercial properties and residents to reduce dust this fall when switching to winter rye grass. The process, known as overseeding, impacts air pollution due to dust generated when scalping existing Bermuda grass. Each year, the department responds to questions and concerns from landscapers, golf course managers and residents doing their best to reduce the dust while working to maintain a grass filled landscape.

 

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

 

• Reduce the area to be overseeded

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 depth of scalping      

Keep dust collection screens and filters in good working order

Hand rake, when possible; learn about leaf blower restrictions: 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 (permitted source) or Rule 300 (unpermitted source), which states that the emissions cannot exceed 20 percent opacity. In addition, visible emissions cannot travel beyond the property line.

 

According to MCAQD, a commercial property owner and/or operator must also keep a record of the control measures used to reduce dust. Examples of dust control measures include, but are not limited to, water application, track out control devices and street sweeping.

 

The Air Quality Department relies on citizens to help improve air quality. Residents may report air quality violations or dust control issues by calling the department at 602-372-2703 or filing a report online at www.maricopa.gov/aq under the “Contact Us” tab.
