On January 15, 2016, EPA issued a proposed rule to amend 30 subparts under the Mandatory Greenhouse Gas Reporting Rule (MRR). There are a total of 46 subparts under the rule. The proposed rule is expected to be finalized in 2016; therefore the upcoming annual report due on March 31, 2016 covering reporting year (RY) 2015 greenhouse gas (GHG) emissions will not be affected by the proposed rulemaking.
The proposed amendments address several types of changes including:
- Streamlining implementation
- Improving data quality and consistency
- Updating provisions to better reflect certain industries' processes and emissions
- Amend confidentiality provisions related to the proposed amendments
The changes range from minor corrections and clarifications to significant changes regarding applicability and emission calculation and monitoring methodologies. EPA intends to phase-in the applicability of the amendments over multiple years, RY 2016 through 2018, according to the subpart affected (see table below).
|Subparts Affected||Reporting Year Affected||Annual Report Affected|
|RY 2016||March 31, 2017|
|RY 2017||March 31, 2018|
|RY 2018||March 31, 2019|
