As the relief wells inched closer, a BP video circulated talking about
the success BP has had with its last 40 relief wells. If
these two work, BP will cutoff the flow in August.
See the videos at BP's site. On July 4th tar balls made it into Lake Pontchartrain thru the
Rigolets. The state closed fishing east of the Highway 11 bridge. The
worst case scenario seemed to be unfolding before our eyes.
On
July 15 BP was able to install a new capping stack on the blow out
preventer and stop the flow of oil into the Gulf. By the 16th it was
clear that pressures inside the well were above critical levels but
lower than BP and National Incident Commander Adm. Thad Allen wanted.
Debate ensued. Did the low pressure indicate a leak or was it just a
sign that three months of flow had depleted the reservoir. The well
remained capped and the decision emerged that it could remain that way
until the well could be killed. On August 5th BP completed cementing the well from the top in a procedure BP calls static kill.
By July 15, 230,000,000 gallons of oil had been released into the Gulf
at the rate of 60,000 bbls per day. (Later 205,000,000 gallons will become the official spill volume.) By comparison, the Exxon Valdez
released 11,000,000 gallons. The 1979 Ixtoc spill was about half as
large as the Deepwater Horizon spill. Its less than a drop in the bucket as the Gulf contains 643 quadrillion gallons of water to which we have now added 0.3 ppb oil.
A Coast Guard report
released July 20th indicated that 50% of the leaked oil
had evaporated or biodegraded. 15% had been contained or had washed
ashore; 5% had been burned;
and 2% had been captured by skimmers. This leaves 28% of the leaked oil
or about 70,000,000 gallons still floating around out there.
On
July 16 the state reopened recreational fishing. Local anglers were
ecstatic. Fishing was the best it had been in years. Everyone was
catching their limit. Commercial fishing remained closed. Oyster beds
may have had the worst of it. The state had opened the freshwater
diversions to protect and flush the marsh. Affected by the change in
salinity, oysters died by the billions.
July wasn't quite over.
On July 23 TS Bonnie crossed Miami before arriving in New Orleans as a weak Tropical Depression. Bonnie had just enough energy to stir the oil in the Gulf and interfere with repair operations before it wet down the city.
The
good news is that New Orleans has not flooded to any extent in the past
five years.
Around New Orleans the wetlands are
still dying. Opening the diversions may be the best news we've heard lately. Keeping them open permanently could be better yet. The river remains full of fertilizer laden silt
and fresh water needed to keep the wetlands vital. Coastal destruction is a problem that would be solved by a rational
population. Shouldn't we?
On the national economic scene the big
issues are still energy and education. Although answers are available
for both problems (if you are curious dig though this site for my
ideas), our stubbornness continues to prevent us from acting on either.
