4-10 REPORT CENTRAL LAKE ONTARIO CONSERVATION AUTHORITY DATE: August 18, 2011 FILE: IMS: ACAD19 S.R.: 4975-11 APPROVED BY C.A.O. MEMO TO: Chair and Members, CLOCA Board of Directors FROM: Chris Darling, Director, Development Review & Regulation SUBJECT: Amending Ontario Regulation 42/06, Central Lake Ontario Conservation Authority: Regulation of Development, Interference with Wetlands and Alteration to Shorelines and Watercourses Purpose The purpose of this report is to recommend the adoption of amendments to Ontario Regulation (O. Reg.) 42/06 to bring it into conformity with recent amendments made to Ontario Regulation (Generic O. Reg.) 97/04 and to clarify the intent of certain provisions in the Regulation. Background O. Reg. 97/04 under the Conservation Authorities Act is an approved template or generic regulation that dictates the form and content of each individual conservation authorities regulation. Pursuant to S. 28 of the C.A. Act and O. Reg. 97/04, in 2005, CLOCA developed an individual regulation, O. Reg. 42/06 Development, Interference with Wetlands and Alterations to Shorelines and Watercourses Regulations which was approved by the Province in 2006. In March of 2011, the Province approved amendments to O. Reg 97/04 as described below. Each individual conservation authority regulation made under S. 28 of the C.A. Act must be subsequently amended and approved by the Minister of Natural Resources to reflect and enact the new amendments to the O. Reg. 97/04. The amendments are intended to simplify, streamline and clarify the permitting process that conservation authorities undertake. The Ministry proposes three types of amendments for consideration by conservation authorities: 1. CA Act S. 28 regulation amendments to conform to the amended O. Reg. 97/04: Enabling the conservation authority to delegate its powers under the regulation including the power to make positive permit decisions to the conservation authority s executive committee or conservation authority employees. Extending the maximum period of validity of a permit from 24 months to 60 months under certain criteria and conditions. cont d..2
S.R.: 4975-11 August 18, 2011 IMS: ACAD19 Page 2 2. MNR promoted amendments that include: An amendment to clarify the intent of the regulation by deleting a clause that has led to legal interpretations of the regulation inconsistent with legislative intent; 3. Housekeeping Amendments confirmed through a survey of conservation authorities by Conservation Ontario in 2010 and considered eligible by the Ministry. Attachment 1 to this report illustrates the recommended additions and deletions to the current O.Reg. 42/06. Attachment 2 to this report illustrates the final draft of the O.Reg. with all amendments incorporated. Process for Approving and Amending Individual CA Act S. 28 Regulations The Ministry requires a resolution of adoption from the Authority Board of Directors in order for the amended O. Reg. to proceed. Following the adoption, the Ministry will review each amendment and provide written notification as to the outcome of their review. When all conservation authority amendments have been reviewed by the Ministry, the consultation and approval process follows these general steps: MNR posts the 36 individual regulations for public consultation on Ontario s Regulatory Registry for 45 days MNR staff compile comments and submissions received and make recommendations based on comments and may consult conservation authorities as required MNR sends the draft proposed 36 regulations to Legislative Counsel to draft new regulations with new numbers MNR sends to the conservation authorities the Legislative Counsel written regulations for conservation authority board review and resolution to approve the proposed amended Regulation Conservation authorities send their board resolution and signed original proposed regulation to MNR MNR submits an approval package for the Minister s consideration If approved by the Minister, each conservation authority will receive a letter to that effect and the new regulations will come into effect when filed and posted on elaws (approx. March, 2012) Staff Comments 4-11 The amendments illustrated in Attachments 1 and 2 to CLOCA s O-Reg 42/06, Development, Interference with Wetlands and Alterations to Shorelines and Watercourses Regulation have been prepared in conformity with the provisions outlined in Section 28 of the Conservation Authorities Act and the amended Ontario Regulation 97/04, and as per the eligible amendments identified by the Ministry of Natural Resources. The recommended amendments to O.Reg 42/06 will assist in streamlining the approval process and add clarity to the intent of certain provisions in the Regulation. The amendment to allow the delegation of positive decisions to staff is in effect very similar to the current protocol that CLOCA adopted in 2006. Currently, the only permit applications that are referred to the Authority Board for a decision are those that involve alterations to a watercourse and any application considered to be major development within a flood or erosion hazard. All other routine/minor permit applications are issued by staff and later endorsed by the Board at the subsequent meeting. The amendment will formalize CLOCA s current practice and will allow for continued efficiencies and streamlining in processing permit applications. Once the new O.Reg. comes into effect, staff will prepare a subsequent report advising the Board with recommendations for delegated approvals. cont d.3
4-12 S.R.: 4975-11 August 18, 2011 IMS: ACAD19 Page 3 The recommended amendment to allow for extended time periods for permits up to 5 years under specific circumstances will also result in increased efficiency and improved client service while maintaining the integrity of the regulations. Generally, the need to issue a permit beyond two years will be infrequent and will apply to applications such as major infrastructure works spanning over multiple years. All other recommended amendments are meant to clarify the implementation of the regulations and do not alter the intent. For example, the current Regulation contains a provision that has been interpreted incorrectly that development approved under the Planning Act is exempt from requiring permits under the Conservation Authorities Act. The intent was not to allow for a blanket exemption as planning approvals do not necessarily address hydrologic interference and/or site alteration matters. Once the new regulation takes effect, staff will apply the revisions to all permit applications not yet approved. RECOMMENDATION: Whereas a local Conservation Authorities Act Section 28 Development, Interference with Wetlands and Alterations to Shorelines and Watercourses Regulation has been prepared in conformity with the provisions outlined in Section 28 of the Conservation Authorities Act and the amended Ontario Regulation 97/04, and as per the eligible amendments identified by the Ministry of Natural Resources, THEREFORE BE IT RESOLVED THAT the Central Lake Ontario Conservation Authority adopts the proposed amendments to the subject regulation as illustrated in Attachment 1 and 2 to this report, AND THAT the said regulation proposal with eligible amendments be submitted to the Ministry of Natural Resources for review, posting on the Regulation Registry, and depending on the results of the registry posting, for subsequent consideration for approval by the Ministry of Natural Resources, AND THAT a copy of Staff Report #4975-11 be forwarded to the partner municipalities within CLOCA s watershed.
