Mandatory GHG Reporting 
Guidance Documents

This page updated March 7, 2013

Overview

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 (MRR), effective January 1, 2013. Please read the Legal Disclaimer for Guidance Documentation as it pertains to the posted documents. Additional information is available at the GHG reporting home page.

• Applicability of 2012 MRR Revisions for 2013 and 2014 reporting
     -  Attachment 1 - Sortable spreadsheet listing revisions to regulation
• Unit Aggregation: Requirements for unit aggregation when reporting stationary combustion sources and how to enter unit data into the Cal e-GGRT system.
• Missing Data Substitution Provisions: Requirements and guidance for using alternate data when primary required data are not available.
• Electricity Generation and Cogeneration: Regulatory requirements and detailed examples for reporting.
• Fuel Suppliers: Guidance on determining applicability, data reporting, and covered emissions calculations for transportation fuel, natural gas, and other fuel suppliers.
• Refinery Product Data: Guidance describing the product data reporting requirements for refineries and Attachment 1 spreadsheet.

Emissions Data Metering and Calibration

• Meter Calibration and Accuracy (coming soon): Describes the current requirements for measurement accuracy, calibration, field accuracy, and other information. Note that requirements for meter calibration and measurement accuracy were different for the first year of reporting (2011 data reported in 2012) versus current reporting.

• Rule Applicability (under revision): Determine if a facility or entity is subject to reporting under the GHG reporting rule.
• Applicability Quick Reference (under revision):  Diagram and Table
• Reporting Dates and Applicability (under revision): Submittal dates for regular and abbreviated reports, stationary combustion only applicability, what to do if below 10,000 tons CO2e, reporting 2011 versus 2012 data.
• Cessation of Reporting (under revision): What to do if emissions drop below the reporting threshold, there is a permanent facility shutdown, or there are no electricity imports or exports (for electric power entities).
• Fuel versus Emissions Table - To assist with applicability determinations, this table provides the approximate quantities of fuel that need to be burned to produce either 10,000 or 25,000 metric tons of CO2 emissions. Values provided are only approximations and the full requirements of section 95101 of the regulation must be evaluated to make a definitive applicability analysis.
• Fuel Supplier Applicability Calculator - By entering fuels supplied, this spreadsheet provides an estimate of the CO2 emissions produced from the complete oxidation of the fuels, which can assist in determining if GHG reporting is required under the regulation.
• Minimum Allowable Tiers (Methods) Under Section 95115  - This table and flow chart describe which emission estimation tiers may be used for estimating emissions from stationary fuel combustion sources under the ARB regulation. The ARB requirements for tier selection in section 95115 differ from the U.S. EPA requirements in Subpart C.

Product Data

• Product Data Reporting Guidance (under revision).  This guidance describes the differences and outlines the product data requirements for 2011 data, and 2012 data and onward.

Electric Power Entities

• Electric Power Entity Guidance: Includes a variety of resources for Electric Power Entities.
• Qualified Export Adjustment Calculation: This guidance document gives an overview of the accepted method to calculate the Qualified Export adjustment.

Petroleum and Natural Gas Systems (Subparticle 5 - Subpart W)

• Guidance Page (REVISED 2013): Resources to assist in reporting data required for petroleum and natural gas systems.

REGULATORY ADVISORY

Product Data Reporting - Regulatory Advisory and Guidance

• Product Data Reporting Requirements: Product data requirements are different for initial 2011 data than for subsequent data submissions, as described in the product data regulatory advisory.
