Environmental and Sustainability Practices Flashcards

What is the primary greenhouse gas concern associated with natural gas distribution systems?

Answer: Methane emissions from pipeline leaks (fugitive emissions)

Methane, the primary component of natural gas, is a potent greenhouse gas; fugitive emissions from leaks in distribution systems are a significant environmental concern.

What is a 'Leak Detection and Repair' (LDAR) program?

Answer: A systematic program to find and fix gas leaks in the distribution system to reduce fugitive methane emissions

LDAR programs use periodic surveys and monitoring technology to identify and promptly repair gas leaks, reducing both safety hazards and methane emissions to the atmosphere.

What does 'renewable natural gas' (RNG) refer to in the context of gas distribution?

Answer: Biogas (methane) produced from organic waste sources that is upgraded to pipeline quality

RNG is pipeline-quality methane derived from the decomposition of organic materials such as landfill gas, wastewater biogas, or agricultural waste, reducing reliance on fossil fuels.

Which federal agency regulates air emissions from natural gas compressor stations and processing facilities?

Answer: EPA (Environmental Protection Agency)

The EPA regulates air emissions including methane, VOCs, and NOx from natural gas facilities under the Clean Air Act.

What is the purpose of 'reduced emissions completions' (green completions) at natural gas wells?

Answer: To capture gas that would otherwise be vented or flared during well completion, reducing emissions

Green completions capture gas and liquids that flow back during well completion rather than venting or flaring them, significantly reducing methane and VOC emissions.

What is 'pipeline integrity management' and how does it relate to environmental protection?

Answer: A systematic program to assess and maintain pipeline safety that also reduces leaks and associated emissions

Integrity management programs identify and address pipeline risks, reducing the likelihood of leaks and failures that could harm both people and the environment.
