What is the environmental benefit of replacing cast iron or bare steel gas mains with plastic pipe?
Answer: Plastic pipe eliminates corrosion-related leaks, reducing fugitive methane emissions and improving safety
Old cast iron and bare steel mains are prone to corrosion and joint leaks; replacing them with polyethylene pipe reduces fugitive methane emissions and eliminates safety hazards.
What is the role of a 'methane emissions inventory' for a gas distribution company?
Answer: To quantify and report greenhouse gas emissions from system operations for regulatory compliance and emission reduction planning
An emissions inventory systematically measures and reports methane releases from all sources in the distribution system, enabling regulatory compliance and targeted reduction efforts.
What does EPA Subpart W require of natural gas distribution companies?
Answer: Annual reporting of greenhouse gas emissions to the EPA
EPA 40 CFR Part 98 Subpart W requires natural gas distribution companies to annually report greenhouse gas (primarily methane) emissions to the EPA's Greenhouse Gas Reporting Program.
What is 'directed inspection and maintenance' (DI&M) in the natural gas industry?
Answer: A targeted leak detection and repair approach that prioritizes fixing the largest emission sources first for maximum environmental benefit
DI&M focuses resources on identifying and repairing the largest leaks first, maximizing emission reductions per dollar spent compared to uniform leak survey programs.
What environmental advantage does natural gas have over coal and oil when burned for energy?
Answer: Natural gas combustion produces significantly less CO2 per unit of energy and nearly no particulate matter or sulfur dioxide compared to coal or oil
Natural gas combustion emits roughly 50% less CO2 than coal and 30% less than oil per unit of energy, with negligible sulfur dioxide and much lower particulate emissions.
What is the purpose of 'atmospheric monitoring' near natural gas compressor stations or storage facilities?
Answer: To detect and quantify methane or other emissions to ensure compliance with air permits and protect community air quality
Atmospheric monitoring around gas facilities measures pollutant concentrations to verify compliance with air quality permits and provide early warning of equipment leaks or malfunctions.
