Proposed Gas STAR Gold Program
Proposed Gas STAR Gold Protocols
EPA proposes that facilities will achieve Gas STAR Gold status by implementing all applicable proposed Gas STAR Gold protocols at a facility. In cases where multiple technologies or practices are identified under a specific protocol, they are proposed in rank order based on applicability.
The proposed Gas STAR Gold protocols are intended to address high-emitting methane emissions sources using readily available cost-effective technologies and practices.
EPA proposes that, in order to achieve Gas STAR Gold status, each facility would need to implement 100 percent of applicable protocols in a given year unless there is an exemption clarified in the protocol—for example, for safety or emergency reasons. Facilities would document their achievement through annual reporting of relevant supporting data to EPA annually.
View the Proposed Protocols
The proposed Protocols would apply to emission sources in the following segments of the petroleum and natural gas industry:
Off P – offshore production
On P – onshore production
GB – gathering and boosting
Pc – onshore natural gas processing
T – onshore natural gas transmission
S – onshore natural gas storage
LNG S – LNG storage
LNG I&E – LNG import & export
D – natural gas distribution
The proposed protocols are available in the Gas STAR Gold Program: Proposed Framework (PDF) (17 pp, 375K, About PDF), Appendix A (page 9). EPA will soon release a detailed technical background document to provide further information on the proposed protocols, implementation practices, definitions and data elements to be submitted to EPA annually to achieve and maintain Gas STAR Gold status for each facility.
Implementation of the Gas STAR Gold program is intended to ensure that facilities provide credible, transparent and consistent reporting with minimal partner burden by leveraging existing information and programs to the extent possible. For example, EPA proposes to streamline reporting requirements for facilities seeking Gas STAR Gold status by using existing facility definitions from the petroleum and natural gas systems source categories (Subpart W) of the Greenhouse Gas Reporting Program (GHGRP) and leveraging data reported to the GHGRP to the extent practicable.
This table provides a summary of the major sources proposed under the Gas STAR Gold program and their associated oil and gas industry sectors.
