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
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).
Oiled Road Maintenance
In 2020, the oiled road inventory was reduced from approximately 12 miles to 5.7 miles. Roads identified to be removed from the oiled road inventory will be transitioned to a gravel surface road as they dehydrate. A maintenance program for patching, rip/relaying, seal coat application, snow plowing, and sanding is used to maintain a safe driving surface.
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
- 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.
In 2020, a 2.75-mile section of pavement (ATCO Electric Access Road – Township Road 410 from Secondary Highway 855 east to Range Road 154) will be removed by milling the pavement. The budget for this project is $93,000. This section of road has and continues to have issues with heaving and rutting due to settling of reclaimed land from a previously mined area. Once completed, this section of roadway will be maintained as a gravel surface.
The following roadways are designated pavement roads:
|ATCO Power Plant Road||Twp Rd 410 to ATCO Power Plant||1.75 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|
