New Version of ERCBH2S Available for Testing and Feedback and Implementation Plan for Directive 071 - October 1, 2009
The Energy Resources Conservation Board (ERCB) announces the release of an updated version of ERCBH2S (Version 1.20 Beta), available on the ERCB Web site page for Directive 071: Emergency Preparedness and Response Requirements for the Petroleum Industry for testing until November 13. Feedback is requested to be sent by e-mail to directive071@ercb.ca. A finalized Version 1.20 will be released after feedback has been assessed.
In addition, the ERCB has released EnerFAQs 13: Emergency Response Preparedness in the Energy Industry, which is available on the ERCB Web site www.ercb.ca, as well as in print from Information Services, 640 – 5 Avenue SW, main floor; telephone: 403-297-8311; fax: 403-297-7040;

A new draft of Directive 071 is expected to be released for stakeholder comment in early 2010.Once the 2010 edition of Directive 071 is finalized and issued, existing sour production facilities currently operating under the 2005 edition of Directive 071 must revise and submit required emergency response plans (ERPs) to the ERCB’s Emergency Planning and Assessment section within two years of date of issuance.
For more information on the release of the ERCB H2S model, please refer to Bulletin 2009-32 and its attachments.
Companies may use Version 1.20 Beta to calculate EPZ sizes and create ERPs. However, the results must be verified by the finalized Version 1.20 when it is released, and any changes to EPZ sizes identified must be revised in the ERP.
Important Notice Concerning ERCBH2S – July 3, 2008
The ERCB has released a revised version of the ERCBH2S program, along with an updated Technical Reference Document and User Guide. All ERCB submissions must be made using the most current version of the software. Program changes are identified in a file titled ‘What’s New’ available with the new program.
Users are strongly encouraged to keep all existing modelling scenarios as ERCBH2S export files (.csv format) using the batch file export process exactly as described in Chapter 3 or Chapter 8 of the ERCBH2S User Guide. If users made use of the blank ‘Notes’ page in ERCBH2S and wish to retain these notes, the pages must be saved separately. The ERCBH2S batch export process does not save this information as part of the .csv file.
When using a new version of ERCBH2S, existing scenarios (properly saved as ERCBH2S export files) can be imported to a blank Batch page in the new version. ‘Reading’ these scenarios to the new Inputs page will reveal any fields with missing or invalid user entries. This must be done prior to activating the ‘Calculate EPZ’ or ‘Batch Calculate EPZ’ program command in the new version. Note that because a new row/column has been added for the liquid well H2S release rate, copying and pasting existing spreadsheets for input to the new version is not recommended. Instead utilize the batch export/import process discussed earlier in this message.
Calculation results imported from previous versions of ERCBH2S are not valid until they have been verified by ‘re-running’ the inputs through the new version.

The ERCBH2S Model and its User Guide may be updated from time to time on the ERCB’s website. Checking the version numbers and update dates currently shown on the ERCB’s website against the version you are using will reveal if a newer version should be downloaded. Uninstalling previous versions of the ERCBH2S Model is not necessary – the new version automatically removes the old version. If the user installed the previous ‘test’ version 119 beta of the model (it was the xla and xls files ONLY), it can only be deleted by the user – it is not automatically overwritten with installation of the new program.
