Providing You With Effective Dust Management Solutions

Dust Management Plans, known formally as Best Management Practice (BMP) Plans, are effective tools at helping Ontario businesses manage fugitive emissions of particulate matter. Best management practice plans are generally prepared in support of Environmental Compliance Approval (ECA) applications, or to support construction activities where nearby control of dust is required.

Dust Management Plans in support of ECA applications are prepared for Ontario facilities with significant onsite road dust emissions, most commonly from unpaved roads or haul roads. Certain industries such as aggregate steel and recycling can also track out significant road dust from paved roads. In addition to dusty roadways, Best Management Practice Plans also cover outdoor storage piles which are subject to wind erosion.

Preparing a Dust Management Plan or BMP is advantageous in that fugitive dust emissions from roads and storage piles can be excluded from the emission summary and dispersion modelling (ESDM) report. This can be a significant compliance tool for the industry provided:

  • the nature of the dust emissions are not likely to pose a health risk
  • there is a formalized fugitive dust control plan in place

In general, this means that Ontario facilities are able to remove all contaminants from the ESDM report associated with road dust and storage pile releases. However, certain industries, while not required to consider particulate matter as a release, are required to consider individual metals which may be released from these fugitive dust sources. Those industries are the Mining Sector, Primary Metal Manufacturing (NAICS 331), and Fabricated Metal Product Manufacturing (NAICS 332).

Controlling Fugitive Dust

At the heart of a Dust Management Plan is how a facility intends to control fugitive dust emissions from roads and storage piles.

Common ways of controlling road dust:

  • Reducing vehicle speed by posting speed limits of 5 or 10 km/hr
  • Wet sweeping with water or chemical dust suppressants
  • Combining wet sweeping with vacuum truck operations

Things to consider when developing a road dust control plan.

  • Precipitation – generally dust control on roads during rainy days or when there is snow cover is not required
  • Sweeping frequency – more often on hotter days as the evaporation rate is higher
  • Silt loading analysis – high traffic areas should have low silt material
  • Minimizing track out – utilize or create a tire washing station

Controlling wind erosion from storage piles:

  • Minimize the drop height for load/unloading
  • Wind shield
  • Surface wetting
  • Onsite transport through closed vacuum conveying systems

The Ministry of Environment and Climate Change (MOECC) requires that at a minimum the following information be provided in a Best Management Plan for fugitive dust:

  • Identify the sources of fugitive dust emissions within the facility
  • Review the composition and size range of the fugitive dust (assessment of health risks)
  • Describe how fugitive dust will be controlled from each identified source
  • Contain a schedule by which the plan will be implemented
  • Describe how the plan will be implemented, including training of facility personnel
  • Describe inspection and maintenance procedures; and
  • Describe methods of monitoring and record-keeping to verify compliance with the plan.

How Rubidium Environmental Can Help

Rubidium has extensive experience designing practical Dust Management Plans that take into account the operating realities of your facility. Combining the process and capital considerations, our Best Management Practice Plans will help you mitigate public complaints from nuisance dust related issues. Our engineers can assist you in creating the appropriate dust control solutions. Each facility is different, and our dust control solutions are custom tailored to your operations.

Pits and Quarry operations are subject to specific requirements under the Aggregate Resources Act (ARA). Specifically, section 3.1 requires that “dust will be mitigated on site”. Rubidium Environmental can assist facilities in designing and implementing effective dust control strategies. One of the challenges with controlling dust is determining where the most probable points of impact are. More often than not, we see ‘overkill’ solutions being applied. While these ‘overkill’ tactics may produce an adequate result, they are not considered to be the most effective, or cost conscious solution. However, by focussing our efforts on the high volume impact points that need to be controlled, operators can efficiently eliminate the nuisance complaints, at a lower cost to the company.

Construction Dust Control

Controlling fugitive dust from construction operations can be challenging, but our engineers can help simplify the problem. The most common concern that stems from construction dust is silica (quartz), as it is a known carcinogen. While most construction workers in dusty environments are outfitted with proper personal protective equipment (PPE), construction companies must exercise due-care in minimizing dust emissions off of their construction site(s).

Control of dust from construction sites is regulated by the Ministry of Environment and Climate Change and the Ministry of Labour. Certain construction projects may require ambient air quality monitoring if the work is being done in or near urban spaces. The use of dispersion modelling can assist in determining the most impacted areas. Part of effective dust management in construction sites involves the use of wind speed and direction. More and more often are we now seeing construction sites with weather stations that monitor the wind speed and direction. Administrative controls can be placed on certain high dust operations when the wind speeds reach a certain threshold, and are oriented in specific directions.

Every summer we see construction sites get stop work orders because of nuisance dust issues. Rubidium can help you prevent this from happening to your operation by developing dust control techniques specific to your project. We can even develop an ambient air quality monitoring program if necessary.
