Dust Management Plans, known formally as Best Management Practice Plans (BMPP), 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).
