Mandatory GHG Reporting - Petroleum and Natural Gas Systems Guidance
This page updated June 11, 2013
These guidance documents are provided solely for informational
purposes to assist reporters in
meeting the requirements of the Regulation for the Mandatory Reporting
of Greenhouse Gas Emissions. Please read the Legal Disclaimer for Guidance
Documentation as it pertains to the posted documents.

GHG reporting home
The petroleum and natural gas systems reporting requirements are found in subarticle 5 of the Regulation for the Mandatory Reporting of Greenhouse Gas Emissions (MRR). Below are documents to assist reporters subject to the petroleum and natural gas systems requirements as outlined subarticle 5 of the MRR.
Natural Gas Systems (Subarticle 5) Guidance
- Subarticle 5 - Emissions Guidance: Provides guidance on emissions reporting for subarticle 5. It includes information on common pipe, best available monitoring methods, and compressors.
- Subarticle 5 - Product and Benchmarking Data Guidance: Includes reporting guidance on data elements outlined in section 95156 of the MRR.
- Subpart W Reporting Guidance (under revision): Summarizes the reporting process for onshore petroleum and natural gas production reporters. Gives a detailed overview of the emissions that need to go in the Subpart W xml upload file and the emissions that need to be reported in Subpart C of Cal e-GGRT. Discusses the combustion emission sums that need to be associated with each particular thermal and other than thermal production value.
- Facility Definition for Petroleum and Natural Gas: Companies that produce petroleum and natural gas, and process, distribute, or store natural gas have complex "facility" configurations, making it challenging to determine which activities are included within distinct facilities for the purposes of reporting. This guidance describes how activities for these reporters should be aggregated and reported.
- Subpart W
Source Applicability Matrix:
Summarizes which source types must be reported by each Subpart W
Industry Sector (e.g., onshore petroleum and natural gas production,
LNG storage, etc.)
- Calculating Emissions from Leaks: ARB is extending the use of population counts for leak emission calculations for the onshore petroleum and natural gas production industry segment.
ARCHIVE for 2011 Data Reporting Only
- Corrections to Calculation Methods: Updates the typographical errors in the November 30, 2010 version of Subpart W. Please note that the computational errors were also corrected in the calculator spreadsheet located on the Cal e-GGRT help page.
Methods Regulatory Advisory: ARB
is extending the use of best available monitoring methods (BAMM) for
specified parameters used to calculate greenhouse gas emissions for
petroleum and natural gas systems as described in the regulatory
