Pursuant to SB 1371, Leno - Natural gas: leakage abatement, the California Public Utilities Commission (CPUC) requests that the following information be transmitted to the CPUC and the State Air Resources Board (ARB):
Note - Definitions in Data Request Pacific Gas and Electric R15-01-008 2017 June Report
The following question in the above mentioned data request is answered using the spreadsheets in this Appendix (#3):(6) Calculable or estimated fugative emissions and non-graded gas leaks, as defined in Data Request Pacific Gas and Electric R15-01-008 2017 June Report.
Notes:
Use a formula-derived value with the formula used in the Annual Emissions column. Do not use a copy and paste-as-value.
At the end of Annual Emissions Column, add a summation total in a cell for a column total, and then highlight orange.The emissions captured on this tab represent the emissions associated with the operational design and function of the compressor. Any intentional release of natural gas for safety or maintenance purposes should be included on the Blowdowns worksheet.

PG&E does not track emission associated with unintentional leaks at a Compressor level that if repaired would not be leaking. Leaks and Emission are tracked at the Component Level only
Sum Total - Provided as an example.
The emissions captured on this tab represent the emissions associated unintentional leaks that if repaired would not leaking. If the Compressor is releasing gas or "bleeding" as a result of
its design or function then it is not to be captured in this tab.

Pursuant to SB 1371, Leno - Natural gas: leakage abatement, the California Public Utilities Commission (CPUC) requests that the following information be transmitted to the CPUC and the State Air Resources Board (ARB):
Note - Definitions in Data Request Pacific Gas and Electric R15-01-008 2017 June Report
The following question in the above mentioned data request is answered using the spreadsheets in this Appendix (#3):(6) Calculable or estimated fugative emissions and non-graded gas leaks, as defined in Data Request Pacific Gas and Electric R15-01-008 2017 June Report.
Notes:
Use a formula-derived value with the formula used in the Annual Emissions column. Do not use a copy and paste-as-value.
At the end of Annual Emissions Column, add a summation total in a cell for a column total, and then highlight orange.
The emissions captured on this tab represent the emissions associated with the operational design and function of the component. Any intentional release of natural gas for safety or maintenance purposes should be included on the Blowdowns worksheet.
