Transcription

1 Proposed Revisions to Regulation 22/04

2 PEO/EDA/ESA Issues Wording of 7(1)(b) and 8(4) Assembly by a P. Eng, CET or competent person PEO considers assembly as engineering work Potential Regulatory conflict Potential confusion re delegation of authority

3 Background Policy Intent and Principles Reg. 22/04 is objective based Electrical work forming part of a distribution system shall be based on engineering plans, drawings and specifications Plans, drawings and standard designs must be reviewed by a license holder and if satisfied that the safety objectives are met the licence holder shall provide a report to that fact ESA will rely on the license holder obligations under the PEO Act and Regulations and will consider sealed and signed plans, drawings and specifications as meeting the safety requirements of Reg. 22/04 Based on this ESA deems approval

4 Background Cont d Policy Intent and Principles Before putting a distribution system into use it shall be inspected to confirm that it has been constructed properly and is safe for use ESA deems the installation approved for use based on the licence holder report that an inspection was conducted and that the installation meets the safety objectives

5 Status Reached agreement with PEO on proposed revisions Revisions are based on the PEO/EDA letter to ESA and the Design Working Group input Agreed to replace reference to P. Eng with a licence holder

6 Status Addressed the PEO s concern regarding the potential conflict between PEO Act and Reg. 22/04 by rewording 7(1)(b) and 8(4) Clarified the role of the license holder in preparing a report vs a certificate to document that the safety standards have been met at the plan review stage as well as at the inspection and approval of constructions stage

7 Status Clarified that ESA is the approval authority not the licence holder, based on the licence holders report ESA deems approval

8 New wording of Section 7(1)(a) and (b) Before beginning work on an electrical installation that is or may form part of a distribution system, a distributor shall ensure that the installation work is based. a) On engineering plans that have been approved in accordance with subsections (2) to (7) or; b) On engineering standard design drawings or standard design specifications reviewed and approved in accordance with subsections (2) to (7)

22 Cable Locates Working Group (March 29) Support for the one call concept General agreement that there is merit in a common target No consensus on the UAC Resolution could be reached by the group No recommendation regarding adopting a common industry target can be brought forward to the UAC

23 ESA will Cable Locates Next Steps Review the discussions and output from the working group and UAC meetings Continue to solicit feedback from the industry stakeholders Take all relevant information under advisement to determine what is a reasonable time

24 UAC Resolution The electrical distribution industry support and actively engage in discussions with other stakeholders involved in the underground locate issue with the aim of adopting, by November 11, 2006, a common target for responding to locate requests.

25 Review of Reclosure of Tripped Feeder Practices Survey & Research Document and summarize Canadian and US Distributor Practices when reclosing tripped distribution feeders. What standard practice would be most appropriate for Ontario? For Your Safety

26 Background Issue Raised UAC June Action Item Research Statutes/Regulation Court cases and decisions Conduct Survey Analyze Research & Survey For Your Safety

27 Survey sent to 56 Distributors Canada -16 BC- 2 Alberta 2 ON 10 QUE 1 NS 1 California- 5 Colorado-4 in North America United States- 40 Massachusetts 3 Ohio- 4 New York 5 Tennessee 3 Michigan-4 Georgia-4 Virginia 3 Illinois 5 For Your Safety

28 11 - US Safety Related Regulatory Agencies California PUC Colorado PUC Ohio PUC Pennsylvania PUC Georgia Public Service Illinois commerce Commission Minnesota PUC Missouri Public Service Wisconsin Public Service Commission New York State Public Service Commission Michigan Public Service Commission For Your Safety

29 Survey Responses Inconclusive Only 11 responses 10 Ontario, 1 Alberta If an attempt to reclose is made - typically between 0-60 seconds (6 Distributors) Depends on whether the line is O/H or U/G (5 Distributors). 8 Distributors perform visual inspection and /or sectionalize and reclose tripped feeder. For Your Safety

30 Research Statutes and Regulations No statutes or regulations exist IEEE National Electrical Safety Code C2 Part 4 Section 442 F Restoration of Service After Automatic Trip When circuits open automatically, local operating rules shall determine in what manner and how many times they may be closed with safety For Your Safety

31 Court Cases 8 court cases in Canada and US since 1934 Summary The courts acknowledge the use of reclosures as being a practical necessity Typically ruled in favour of the Distributor For Your Safety

32 Conclusions Inconclusive due to lack of participation 11 responses out of 56 Of the 11 who did respond- reclosure practices vary and depend on whether the system is overhead or underground Most perform visual inspection and sectionalize the feeder prior to restoration of service. For Your Safety
