According to the City of Surrey Erosion & Sediment Control Bylaw, the ESC Supervisor

In accordance with the By-law the professional acting as the ESC Supervisor must meet the following criteria:
“ An engineer, biologist, geoscientist, applied scientist, or technologist who is registered and in good standing in British Columbia with a professional organization constituted under an Act, acting under the association’s code of ethics and subject to disciplinary action by that association...”
1.1.1. Role of the ESC Supervisor
The ESC Supervisor is retained by the Developer to monitor, provide advice, and report on the site’s performance under the ESC Permit.
The primary duties of the ESC Supervisor are:
  • Review the proposed ESC Plan, signing off on the validity of the proposed ESC concept to adequately
  • address expected issues on-site 
  • Monitor to ensure ESC facilities are implemented according to the ESC Plan; particularly at the commencement of clearing and grubbing
  • Liaise with the various contractors to co-ordinate the implementation of ESC Facilities in a proactive and diligent manner
  • Conduct site inspections as needed in accordance with this document and on-site construction scheduling to ensure measures are implemented and maintained appropriately
  • Submit site reports to the City in accordance with section 7 of this document
  • Advise the Engineer of Record/Owner of any ESC deficiencies or actions required to be implemented to adapt to changing site conditions or unforeseen problems that arise regarding erosion and sediment control
  • Keep a detailed record of any changes to the ESC Plan and coordinate plan revisions with the plan designer as dictated by the performance of the site
  • Co-ordinate the removal of ESC measures with site operations
  • Monitor and report on the parameters identified in this document
  • Liaise with the City regarding the management of the site under the ESC Permit, and 
  • Provide confirmation reports to the City to facilitate the release of held securities.

It is an obligation of the permit holder to retain the services of an ESC Supervisor at all times. Should this not be the case, then the Permit will be deemed in non-compliance.

1.1.2. Changing the ESC Supervisor on an ESC Permit
The ESC Supervisor registered against a ESC Permit can be reassigned to another individual as long as:
  • The person to whom the role is being designated to meet s the minimum requirements set forth in the ESC Bylaw 
  • The developer submits a new Schedule “D” document completed by the new ESC Supervisor accompanied by a letter acknowledging the change of the ESC Supervisor.
Ensure that the request clearly references the ESC Permit number and that that the change is being made for and that a separate Schedule “D” document is submitted for each ESC Permit that the request is being made for.
Once this information has been received and reviewed; upon approval the City will update the ESC Permit accordingly. Until the changes have been made in the system the previous ESC Supervisor will remain the acting ESC Supervisor unless otherwise agreed to by the City.
1.1.3. Withdrawing services as the ESC supervisor
Should the ESC Supervisor choose to withdraw their services against an ESC Permit, the ESC Supervisor must submit written notification to the City advising of this decision. Until the notification has been received and process ed by the City, the ESC Supervisor is still deemed responsible for the carrying out of the ESC Supervisor’s duties under active permits.
