ERCBH2S – Calculating Emergency Response and Planning Zones for Sour Wells and Sour Pipelines (pursuant to Directive 071)
Current Status
Revised Directive 071 – Emergency Preparedness and Response Requirements for the Petroleum Industry includes a requirement for applicants to use the ERCBH2S computer software for calculating emergency response and planning zones.
ERCBH2S, its user guide and other associated documents are available below.
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. |

Stakeholders are encouraged to read the document entitled “Preface to ERCBH2S Computer Software - Calculating Emergency Planning Zones for Sour Wells, Sour Pipelines and Sour Production Facilities”. This document explains the concepts behind the new requirements and the benefits of the new calculation process. A comprehensive user guide is also available that defines computer system requirements, install procedure and using the software. Comments on ERCBH2S can also be submitted via email to Directive71@ercb.ca (put ERCBH2S in the subject line).
