Stormwater System Amendment for 3M Canada - London, Ontario

Official title: 3M Canada Company - Environmental Compliance Approval (sewage)

Closed Regulations & Permits Environment & Climate
3M Canada wants to amend its environmental approval for stormwater management at its London facility. The changes involve storm sewers, a dry pond, three lift stations, and a water treatment unit. This is a routine industrial permit amendment.

Why This Matters

Live or work near 3M's Oxford Street facility? This permit controls how industrial stormwater is managed before it leaves the site. Nearby residents may want to know how runoff is being treated.

What Could Change

If approved, 3M can modify its stormwater infrastructure including sewers, a dry pond, pumping stations, and treatment equipment. The Ministry may add conditions for water quality monitoring or discharge limits.

Key Issues

  • Are the proposed stormwater management works adequate to protect local water quality?
  • Should additional conditions be placed on the amended approval?
