Sanitary and Stormwater

The Ministry of the Environment, Conservation and Parks (MECP) has recently introduced a modernized approach to the Environmental Compliance Approval application process, now called the Consolidated Linear Infrastructure Environmental Compliance Approval (CLI ECA). This approach is intended to reduce the burden on municipalities, developers and the ministry, while imposing a consistent set of conditions intended to improve environmental protection.

About this process

Our CLI-ECA approval process covers most alterations that meet the preauthorized MECP requirements for the Sanitary Sewage System and Stormwater Management System owned and operated by the Town of Grimsby.

Development projects no longer need to submit individual pipe-by-pipe MECP applications for future alterations; however, they will need to ensure that they:

If the project does not meet the MECP design criteria, the project may still be approved, but requires a direct submission to the MECP.

When to request an alteration

There are two types of alterations related to CLI ECA applications:

  • Sanitary (sewage) collection system: all connected sewage collection works within the Town of Grimsby and owned and/or operated by the Town of Grimsby.
  • Stormwater management system: all connected stormwater management works within the Town of Grimsby and owned and/or operated by the Town of Grimsby,

You need to request a CLI ECA alteration for the following types of projects:

Stormwater Infrastructure Alteration Projects – Additions, Modifications, Replacements and Extensions as defined under CLI ECA 065-S701.

  • Alterations to Storm Sewers, Ditches, or Culverts
  • Alterations to Stormwater Management Facilities
  • Alterations for Third Pipe Collection System

* Reference CLI-ECA 065-S701 for more details on the specific alteration types.

 

Wastewater (Sanitary) Infrastructure Alteration Projects - Additions, Modifications, Replacements and Extensions as defined under CLI ECA 065-W601.

Exemptions to the CLI-ECA Approval Process

You are not required to apply for a CLI ECA alteration for privately owned sewage works on industrial, institutional or commercial land.

For these projects, you may still need an individual ECA from the MECP, or building permit.   

* Exemptions are listed in the respective CLI-ECA’s.
