Today I took the ferry across the bay from Puerto Santa Maria to Cadiz.  Took a bike and rode around the city sea-wall and around the old city center.  It is a great ride around the sea-wall.  It reminds one of the age of some engineering works. For here we have fortifications that have been four hundred years in the making.  I saw forts and castles built three hundred years ago to defend the city from the French, the Brits, and the Dutch, who attacked at different times.

It reminds us that closure of tailings facilities for 100 or even 200 years is but the outcome of the short history of North America, and not something founded in a profound perspective of real long-term history.  Clearly we can build facilities that last four-hundred years.  The people of Cadiz did.

True defense of their small city was a survival issue.  And true that closure of most mine tailings facilities is not anybody’s defense or survival issue.  I accept that social  utility may be the basis of a rejection of a long closure performance period.  But after seeing what I saw today, I cannot accept the reason too often given: we do not know how and cannot do it.

I have spent the past few weeks in Rota, Spain with my son and family.  The sun shines on the house patio—most times. Athough some days the mist endures all day and it is cold.   Today the sun overcame the mists by about eleven a.m., and it was fun to sit in the sun and read John Grisham’s book The Last Juror.Sometimes I come inside and work on the computer.  I read what is written on Mt Polley and update an EduMine course that I am writing on Risk Assessment, Decision Making, and Management of Mine Geowaste Facilities.  For the failure of Mt Polley tailings facility is the best possible current example of the failure of risk assessment, decision making, and management of geowaste facilities we know of.

We grow old.  Let us live in excess and expire in a whirlwind of pleasure.  Let us go from joy to joy and die in contentment.  Let us forget the past and love each new day in the intensity of life well lived.  Let us fade into the mist of a faint fall. And recall past springs and enjoy all new springs.  For life is summer, albeit winter will come. (more…)

This evening I watched the Mariinsky version of Prokofiev’s Romeo & Juliet.  This is the only ballet I like.  Mostly because of the music.  And, I suspect, because once I could recite the entire Shakespeare play.  (I was Friar Lawrence in the  high school production.)  And now in the ballet I can hear the words of every emotion.

The Tyee, a local Vancouver e-newspaper with a decidedly liberal bent today published an article on peer review of Mt Polley.  David Ball is the author of the piece.  I think he did a good job in balancing the opinions. I admit to being hopelessly prejudiced in this opinion.  For if you read David’s piece, you will note that he quotes me and Nordie Morgenstern.  David called me a while ago and asked how I would have gone about preventing Mt Polley and how I would go about preventing future Mt Polleys.  We talked long about peer review.  To his credit he checked what I was telling him by contacting Nordie Morgenstern.  He also established that there is currently only one tailings facility in BC that has a peer review board.

This picture and the others in this posting were taken by me at Knotsberry Farm in California.
A great place to visit and enjoy a terrifying ride along the raging river of insanity.

If you seek a thorough and intelligent analysis of dealing with uranium mill sites (and particularly the tailings facility) take a look at the following–it is an amazingly comprehensive document–and should be required reading for all involved in mine management, regardless of whether the mine is uranium, copper, gold, or something else.

The PowerPoints of presentations from the Tailings and Mine Waste Conference in Keystone are now available.  At least the PowerPoints of those authors who gave permission.  See this link.

They are all interesting, so choose those that interest you.

I recommend the presentation by Steve Vick who is one of the reviewers of the failure of the Mt Polley tailings facility.  He assures me that he compiled the presentation before the failure and there is no connection between what he says in his presentation and what he might say in the panel findings.

The presentation by Franco Oboni touches on the same topics as Vick’s but takes a different approach.

I particularly like the presentation by Craig Benson on the hydrologic performance of final covers.  He concludes that we can and have constructed covers to last for at least 1,000 years.

I am sure there is much to say about these presentations and indeed the other presentations, so please comment.
