Wells Foundry Limited - Approval to register for a technical standard for air pollution (industry standard)

This proposal is to amend an existing registration under the Technical Standards Registry – Air Pollution (Technical Standards Registry) in respect of the Foundries – Industry Standard under the Local Air Quality Regulation (O. Reg. 419/05).

Wells Foundry Limited is a grey and ductile iron foundry facility which manufactures a range of castings such as pump covers, manhole covers and impellers and is located at 1250 Florence Street, London, Ontario. The facility is part of a class identified by the primary North American Industry Classification System (NAICS) code 331511 (Iron Foundries).

The facility is already registered for: suspended particulate matter, various metals and metal compounds, volatile organic compounds, nitrogen oxide and sulphur dioxide (see EBR Registry Number: 012-9065). This application is to add new contaminants to their existing registration. Please see the additional information section for the full list of contaminants in the application.

Registration to a technical standard means that this facility must adhere to all technical and operational requirements in the Foundries - Industry Standard (see link to this notice) for the contaminants they are currently registered for.

Technical standards ensure that facilities are managing impacts on an airshed by installing best available technology. These requirements would replace the air standards for the contaminants that are registered for this facility.

Registration to the Technical Standards Registry is a compliance approach under the Local Air Quality Regulation. It requires that the company demonstrate compliance on an ongoing basis through applicable technical standard requirements set out in the Foundries – Industry Standard. Registration to the Technical Standards Registry does not exempt the facility from the requirements under section 9 of the Ontario Environmental Protection Act, which regulates alterations to plant infrastructure and processes. Therefore a company required to install equipment under the Foundries – Industry Standard is still required to have approval under Part II.1 of the Ontario Environmental Protection Act for that equipment.

The Technical Standards Registry is available on the Ministry of the Environment, Conservation and Parks’ website and sets out the names of all facilities registered in the Registry.
