Produced
Water from Coal Beds
"Produced
water" can kill the environment. The Minster of Energy
and Mines, Richard Neufeld, didn't exactly say that when
he delivered the opening salvo during the March 14th staged
cabinet meeting, but he did say "Produced water
is disposed of under strict guidelines set out in the Waste
Management Act. In some cases, this water is potable. In
fact, we have some of that in B.C. today. It can be used
for communities and for irrigation or livestock, but the
appropriate disposal method is determined after an exhaustive
study and review." Neither Neufeld nor his colleague
Joyce Murray provided any specifics about any "exhaustive
studies or reviews". They did suggest that environmental
protection would depend on a voluntary "code of conduct"
rather than on statute and regulation.
"Produced
water" is the enormous volume of water that is pumped
out of coal beds in order to reduce the water pressure and
release the methane gas. Unlike natural gas which is on
top of oil, which in turn is on top of water, coal bed methane
requires the pumping out of enormous volumes of water in
order to release the gas. The water may be "potable"
but it may also be toxic. In the United States, they have
found (often too late) that the "produced water"
is toxic.
In response
to Neufeld, the Minister of Water, Land and Air Protection,
Joy Murray, said "As Dick mentioned, this water can
be discharged either into the ground or on the surface.
Some of it is quite clean, and some of it is not. It has
compounds in it." "Compounds in it" is another
way of saying poisons! BC does not have a Ministry of the
Environment that will act as an advocate against the poisoning
of our water and land. Minister Murray went on to say "The
kinds of things that will be in this code of practice include
analyzing the quantity of water from a particular set of
wells, the quality of water, the location to which that
water would be discharged and the part of permitting that
the Oil and Gas Commission will do. We'll review and analyze
those issues and follow the code of practice so that we
do prevent and mitigate impacts on the environment."
BC's
environment requires legal protection, but the Campbell
government is offering nothing more than a "code of
practice" for companies who want to pump polluted waters
onto our lands, into our streams, or back into our underground
aquifers.
There
is a reason that the Campbell government chose to lead its
March 14th staged cabinet meeting with yet another rant
about coal bed methane. That reason is probably related
to the enormous threat coal bed methane extraction presents
for our environment.
According
to the US Geological Survey (http://pubs.usgs.gov/fs/fs123-00/fs123-00.pdf)
"To produce methane from coal beds, water must be drawn
off first, lowering the pressure so methane can flow out
of the coal and to the well bore. This water, which is commonly
saline but in some areas can be potable, must be disposed
of in an environmentally acceptable manner. Surface disposal
of large volumes of potable water can affect streams and
other habitats, and subsurface reinjection makes production
more costly. In addition, methane is a greenhouse gas; in
the atmosphere it acts to trap heat and thus contributes
to global warming."
The
US federal representative for the Secretary of the Interior
in Montana has alleged that firms exploiting coal bed methane
have violated the US Clean Water Act (http://www.deq.state.mt.us/CoalBedMethane/pdf/Complaint5-01.PDF).
In Wyoming,
an advocacy group's website
asserts that "
Wyomingites will loose more in
the dollar value of the water pumped on to the landscape
and lost forever, than what the state will get in tax dollars."
Over 12,000 wells have been developed in Wyoming, and that
number is expected to quadruple over the next ten years.
Residents fear environmental degradation as the coal bed
methane industry is given "guidelines" as opposed
to the statutory framework under which coal mines must operate.
British Columbians should have the same concerns as government
discusses "codes of conduct" rather than strict
statutes and regulations for environmental protection.
