Key Environmental Issues Associated with Shale Gas Development
Primary environmental risks associated with shale gas development
1. Contamination of groundwater aquifers with drilling fluids or natural gas
2. On-site surface spills of drilling fluids, fracture fluids and wastewater
3. Contamination as the result of inappropriate off-site wastewater disposal
4. Excessive water withdrawals for use in high-volume fracturing operations
5. Excessive road traffic and degraded air quality

• For optimum long-term development, need to improve understanding of shale gas science and technology
– Government-funded fundamental research– Industry/govt collaboration on applied research– Should also cover environmental research
• Determine and mandate best practice for gas well design and construction
• Create transparency around gas development– Mandatory disclosure of frac fluid components– Integrated water usage and disposal plans
• Continue to support research on methane hydrates

27 MIT Future of Natural Gas study
For buildings, a move to full fuel cycle efficiency (site vs. source) metrics will improve how consumers, builders, policy makers choose among energy options (especially natural gas and electricity).
Efficiency metrics need to be tailored to regional variations in climate and the electricity supply mix.

The potential for gas to reduce oil dependence could be increased by its conversion…into liquid fuels…methanol is the only one that has been produced from natural gas for a long period at large industrial scale.
The US government should implement an open fuel standard, requiring tri-flex-fuel capability for light-duty vehicles.

Nationwide, coal generation displacement with surplus NGCC would:
reduce CO2 emissions from power generation by 20% reduce CO2 emissions nationwide by 8% reduce mercury emissions by 33% reduce NOx emissions by 32% cost roughly $16 per ton/CO2
The displacement of coal generation with NGCC generation should be pursued as the only practical option for near term, large scale CO2 emissions reductions

Large Scale Penetration of Intermittent Wind in Short Term for ERCOT

The principal impacts of increased deployment of intermittent renewable energy sources in the short term are –
• the displacement of NGCC generation• increased utilization of operating reserves• more frequent cycling of mid-range or even base load
plants.

Policy and regulatory measures should be developed to facilitate adequate levels of investment in gas generation capacity needed for large scale penetration of intermittent renewables.
Large Scale Penetration of Intermittent Wind in Long Term
The development or expansion of electric system models is needed to inform the design of policies that would mandate large amounts of solar or wind generation (important for both short and long-term impacts).

DOE and EPA should co-lead a new effort to review and update methane emission factors associated with gas systems, focusing on actual fugitive emissions measurements and cost effective mitigation. Effort should also include oil and coal.
