Proposal summary
We are proposing a technical bulletin for assessing emissions from continuous and batch material drop operations for the aggregate sector. The technical bulletin describes methods for assessing emissions from these sources and provides Ontario-specific data that can be used in these assessments.
Proposal details
The Ministry of the Environment, Conservation and Parks is posting a draft Technical Bulletin regarding approaches for assessing emissions from continuous and batch material drop operations. Continuous and batch material drop sources are activities in which material is dropped, resulting in fugitive dust emissions. Batch material drop activities become a potential source of emissions during discrete material transfer events, such as unloading material from a delivery truck into a storage bin. Continuous material drop activities become a potential source of emissions during ongoing operations, such as transferring material from a conveyer onto a storage pile.
Fugitive dust is a contaminant under the Environmental Protect Act, and the ministry frequently receives dust complaints related to aggregate sector operations.
The purpose of this posting is to seek feedback on the draft Technical Bulletin (technical bulletin included in the supporting material below).
