Dust Suppressant


Strategic locations are targeted for dust suppressant application, which helps reduce the frequency of maintenance and improves safety while mitigating the nuisance of dust to residents and minimizing environmental impact.

Application forms for residential dust suppressant can be found below.

The dust suppressant program consists of the following:

  • MG 30
  • Oil Surface Products
  • Test Products
  • Pavement

MG 30

MG 30 is a water-soluble dust suppressant product, which also has road surface stabilization characteristics that bind aggregate materials, increasing grade strength and thus keeping aggregate on the road. MG 30 has also proven to help reduce washboard, grader maintenance and the frequency for gravelling, thus extending the life of our gravel sources.

In 2020, the use of MG 30 as a dust suppressant product on Arterial Routes has been discontinued. Residents who live on Arterial Routes have the option for MG 30 to be applied in front of their residences for 200 meters, free of charge, during the spring dust suppressant application.

As well, strategic locations will be treated with MG 30 to help reduce the frequency of maintenance; these locations include hills and at intersections.

Residential Dust Suppressant

Flagstaff County will apply MG 30 as a dust suppressant for citizens at the following lengths of applications:

2020 MG 30 Rates
Application Rate – 2 litres/sq. metre
100 m x 7 m Wide = $418.95
200 m x 7 m Wide = $837.90
300 m x 7 m Wide = $1,256.85
400 m x 7 m Wide = $1,675.80
(All prices include GST)

Applications must be received by June 1 (spring application) and August 1 (fall application).

Application form for Spring Application can be found HERE.
Application form for Fall Application can be found HERE.

Oil Surface Products

With the approval of the Rural Road Study, the oiled road inventory was eliminated and oiled roads will be transitioned back to gravel roads. Council's objective to transition oiled roads back to gravel is to be accomplished by 2022. The transitioning roads are maintained by one full-time grader operator. A maintenance program for pot hole patching and rip/relay ensures a safe driving road surface. As oil surface roads deteriorate and patching is no longer cost effective, ripping and relaying is performed. If an oil surface road contains sufficient residual oil, then the surface will be repacked. Once an oil surface road has dehydrated to the point where the oil doesn't bind to the aggregate and the clay from the sub-grade is exposed, this road is then maintained as if it were a gravel road.

Roads remaining with an oil surface:

Specific roads are designated, in procedure, to be maintained with an oil surface treatment to help reduce the frequency of maintenance.

Rge Rd 151, north from Hwy 13 0.4 miles
Rge Rd 425A, south from Hwy 13 1.75 miles
Rge Rd 103, south from Twp Rd 425 1.0 mile
Twp Rd 442, east from Rge Rd 130 2.0 miles
Rge Rd 130, north of Hwy 13 0.2 miles

The oiled surface road, Twp Rd 442, east from SH 869 for 0.4375 miles will follow the same road ban posting as a gravel road.

*** Year round road bans will remain on these roads. ***

50% in the spring, 75% in the summer and fall, and 90% in the winter.


Annually new dust suppressant products are tested to determine whether they are effective, affordable, and environmentally suitable.

In 2019, a test product called Formula 35 was applied to Twp Rd 442:

  • For 3.0 miles, from Rge Rd 170 to Rge Rd 163, at an application rate of 1.5 L/m2.

Formula 35 is a calcium chloride product with a corrosion inhibiter that is sold by the manufacturer as an equivalent to MG 30.

Products that have been tested, evaluated, and have been eliminated are: 

  • No Dust Enviro
  • No Dust
  • Dust Lynx
  • Canola Oil
  • Durasoil
  • Earth Glue
  • Magnesium Chloride

Flagstaff County continues to consult with industry and municipalities to seek out new and alternative products. We also continue to perform testing on new dust suppressant products in search of solutions.


The following roadways are designated pavement roads:

ATCO Power Plant Road Twp Rd 410 to ATCO Power Plant 4.5 miles
County Airport Road Rge Rd 131, north of Hwy 13 0.75 miles
Galahad Access Road Twp Rd 412, west of Hwy 36 4.0 miles
