Natural gas leak management

NATURAL GAS LEAK

2. INTRODUCTION
• The Aliso Canyon gas leak (also called Porter Ranch gas leak and Porter Ranch gas
blowout) was a massive natural gas leak that was discovered by SoCalGas employees on
October 23, 2015.
• Gas was escaping from a well within the Aliso Canyon's underground storage facility in
the Santa Susana Mountains near Porter Ranch, Los Angeles.
• This second-largest gas storage facility of its kind in the United States belongs to
the Southern California Gas Company, a subsidiary of Sempra Energy.
• On January 6, 2016, Governor Jerry Brown issued a state of emergency. The Aliso gas
leak's carbon footprint is said to be larger than the Deepwater Horizon leak in the Gulf
of Mexico.
• On February 11, 2016, the gas company reported that it had the leak under control. On
February 18, 2016, state officials announced that the leak was permanently plugged.

3. DETAILS OF THE DISASTER
• An estimated 97,100 tones (95,600 long tons; 107,000
short tons) (0.000097 Gt) of methane and 7,300 tones
(7,200 long tons; 8,000 short tons) of ethane were
released into the atmosphere, The initial effect of the
release increased the estimated 5.3 Gt of methane in the
Earth's atmosphere by about 0.002%, diminishing to half
that in 6-8 years.

4. 1. Improved monitoring
technology and science
We are working with scientists, utilities and technology providers to
validate new mobile monitoring equipment and develop new scientific
methods to translate the data gathered into actionable information. As
part of this project, EDF is analyzing methane data collected from
specially-equipped Google Street View cars and publishing maps that
show both leak location and relative leak size.

5. 2. Better data means better,
safer systems
• More precise and frequent data on the location and relative size of
methane leaks will enable gas companies and regulators to better
prioritize repairs and infrastructure improvements . This information
will also take what has traditionally been a safety issue for utilities
and broaden the focus to include not only safety, but also the
environmental- and climate-consequences of methane leaks.

6. 3. Leak reduction goals
• Setting performance goals is important for achieving any objective.
That’s why we’re asking gas companies, public utility commissions
and other state officials to review current leak repair criteria and
establish voluntary reduction targets for those leaks that are not
already regulated by state or federal requirements, and to
accelerate repair for those leaks that are.

7. 4. Stronger statutory and
regulatory requirements
• A great deal of progress can be achieved on a strictly voluntary
basis. There are programs in a majority of states to facilitate
accelerated risk-based replacement of pipelines in the natural gas
distribution system. But stronger legal and regulatory requirements
to reduce methane emissions from local distribution systems will
ensure more rapid reductions in methane gas released into the
environment.

8. CONCLUSION
Developing countries are becoming increasingly aware of the importance of disaster
management systems, and increasing efforts are being made to streamline
preparedness, response and recovery mechanisms at all levels. It is well known that
many developing countries, including India, are not always well- prepared to deal
with disasters. A lack of well-developed disaster management plans results in a
severe loss of human life, animal life and property, which could be saved if the
necessary mechanisms were in place. A lot needs to be done to improve the
situation, particularly in regard to livestock. This paper describes in detail, with
particular reference to India, what can be done to care for animals when natural
disasters occur. The authors review various types of natural disasters and their
impact on livestock, and outline different preparedness, response, recovery, and
mitigation strategies. The roles of different agencies, including veterinarians, are
also considered.
