Agree on most points CB. I'd also read about the prior blow out. At some point continued discharge is inevitable, and what I've learned in digging around is that saturating some pyritic soils, whether disturbed or undisturbed, might slow or stop oxidation and reduce metal leaching.
I know you hate hearing about what California does well, but an obvious question occurred to me. How successful have previous efforts been, what have we learned from them, and how much improvement can we expect? I doubt that anyone knows.
Here in the Bay area we have a monitoring program, the Regional Monitoring Program, that is intended to answer that question. http://www.sfei.org/programs/sf-bay-regional-monitoring-program
A tool like this gives you some idea of the effectiveness and cost-effectiveness of what you are doing. Nobody learns from their mistakes unless they take them out and look at them. |

There is an organization called the Mountain Studies Institue. I have worked as a consultant for them, and have also been a supporter. They have been monitoring water for awhile. In addition, the stake holders group is serious about seeing what they are accomplishing.
But, this is new science, and the vastness, and diversity, of the region cannot be overstated. Remember these sites are buried in snow, often in extremely hazardous avalanche prone drainages, for 9 months out of the year. So, identifying the offending source is very difficult.
And, our snow pack water content can vary dramticAlly by year and by basin depending on the direction of the storms. Groundwater can take a significant time to find its way out. Sort of like global warming data...it fluctuates on its own.
I am surprised you heard of the Silver Lake blowout. This a very high alpine lake that had a huge mine that was accessible by a tram that is miles long. It is a major hike to get to. off the beaten path. This was the first I had heard about the "possible" blowout. I may hike up there this weekend.
The blowout you may have heard about is recapped here.

Jonathon is a little bit of a liberal, but does report pretty accurately...he was my neighbor in Silverton for awhile.
Sunday, I revisited Lake Emma...you can drive to it in a robust 4x4. Amazing site. And you are, literally, standing on a 2000 ft high mine below. |

CB--thanks, best coverage I've read yet. That is the blow-out I read about.
I think it will be interesting to watch the Congressional inquiry into this. I would vote for one if I was in Congress; despite my push-back on the right wing craziness, I'm not willing to give EPA a pass. Having overseen a slew of clean-ups, of much less significance, when I worked for the Port of Oakland, it seems to me that they did not have the level of skill needed in their project manager. (This is not unusual--most governmental agencies establish parameters for clean-ups, few oversee them. They rely on public-private partnerships, and the skill of contractors, which is usually the right way to go.)
The most fundamental need on any clean up is a health and safety plan. The potential for exposure of workers to toxic materials is always the starting point, but hydraulic dangers should also be part of that. We will eventually see both the health and safety plan, and the issues raised by the contractor. It will be interesting. |

I do remember the pious claims from the Exxon apologist about how transparent they must be, and how they must avoid paying off foreign powers. Usually known as bribery. They just don't want anyone to know what they actually do. They have been fighting regulations under the Dodd Frank Act--as well as fighting the Act and anything that the Administration does to reduce carbon emissions. They just lost in their battle with Oxfam.
Quote: | A federal judge ruled Wednesday that the Securities and Exchange Commission must finally complete a long-delayed rule that would force oil, gas, and mining companies to reveal how much they’re paying governments in countries where they extract resources.
The ruling in favor of Oxfam America is a partial victory for activists who have been dismayed at the SEC’s sluggish pace in writing the regulation, which is required under the 2010 Dodd-Frank law but has been trapped in legal and bureaucratic limbo for years.
But the order stops short of setting a specific timeline that Oxfam had sought in the lawsuit filed last year, instead telling the SEC to provide the court an “expedited schedule” for completing the rule.
It’s the latest twist in a fierce, years-long legal and lobbying battle over the regulations that have pitted anti-poverty groups against some of the world’s biggest oil companies.
The rule is designed to chip away at the “resource curse” of corruption, conflict, and poverty in energy-rich nations in Africa and elsewhere. It would force SEC-listed oil, natural gas, and mining companies to file reports with regulators that disclose payments to governments in nations where they have projects, such as money for production licenses, taxes, royalties, and more.
Major oil companies such as Exxon have sought to weaken requirements, contending that making detailed payment information public will hobble Western companies competing against state-controlled Russian and Chinese firms that aren’t bound by the rule.
But high-profile activists, including George Soros and Bono, have advocated for the measure. Oxfam and a suite of other groups united under the Publish What You Pay coalition say the flexibility that industry wants, such as keeping specific companies’ disclosure filings out of public view, would gut the rule.
The rule has taken far, far longer than the 270-day deadline in the Dodd-Frank law.
“The Court concludes … that the SEC’s delay in promulgating the final extraction payments disclosure rule can be considered ‘unlawfully withheld’ as the duty to promulgate a final extraction payments disclosure rule remains unfulfilled more than four years past Congress’s deadline,” states Wednesday’s order by Judge Denise J. Casper of the U.S. District Court for the District of Massachusetts.
The SEC completed a version of the rule in August 2012, but the American Petroleum Institute, the U.S. Chamber of Commerce, and other groups challenged the measure in court.
A federal judge sided with industry and threw out that version in mid-2013, prompting the SEC to decide to rewrite it. The SEC previously said that the process could drag well into 2016.
“Today’s ruling compels the SEC to move quickly to provide relief to citizens and investors who have been waiting for strong transparency requirements for more than five years. The task before the Mary Jo White’s SEC is now crystal clear: a rule must be issued urgently,” said Ian Gary, senior policy manager of Oxfam America’s extractive industries program.
An SEC spokesman said the agency is reviewing the decision. |

Would good corporate citizens spill 11 million gallons of crude oil by tolerating an alcoholic skipper? Would that oil still be doing damage decades later? Would apologists try to focus on anything else?
Quote: | By DAN JOLING, Associated Press
ANCHORAGE, Alaska (AP) — Federal scientists have determined that extremely low levels of crude oil spilled by the Exxon Valdez caused heart problems in embryonic fish, a conclusion that could shape how damage is assessed in other major spills.
In a study published Tuesday in the online journal Scientific Reports, researchers from the National Oceanic and Atmospheric Administration found that embryonic herring and salmon exposed to low levels of crude oil developed misshapen hearts.
"Metabolically, they're different," said John Incardona, a research toxicologist at the Northwest Fisheries Science Center in Seattle. "They can't grow as well. They can't swim as fast."
The defects and subsequent vulnerability may explain why the herring population crashed several years after the spill in Alaska's Prince William Sound and has not recovered, scientists said.
The 986-foot Exxon Valdez struck a charted Bligh Reef at 12:04 am March 24, 1989, spilling 11 million gallons of crude oil. At the time, it was the largest spill in U.S. history. Oil extensively fouled shoreline spawning habitat of herring and pink salmon, the two most important commercial fish species in Prince William Sound.
Fish larvae sampled close to high concentrations of oil were found with abnormalities. Little was known in the early 1990s, however, about effects of low-level crude oil exposure on fish in early life stages, according to the study.
Pink salmon declined but recovered. The herring population collapsed three to four years after the Exxon Valdez ran aground and the role of the spill, NOAA Fisheries scientists acknowledged, remains controversial.
The silvery fish is a key species because it is eaten by salmon, seabirds and marine mammals from otters to whales. Four years after the spill, the estimated herring population based on modeling shrunk from 120 metric tons to less than 30 metric tons.
For the study, the scientists temporarily exposed herring and salmon embryos to low levels of Alaska North Slope crude oil before placing them back into clean water. The threshold for harm in herring was remarkably low, Incardona said.
"Herring in particular, they are really, really very sensitive," in part because their eggs and yolk sacs are so much smaller.
After exposure, scientists transferred fish embryos to clean water, let them grow for seven to eight months and tested them in swim tunnels.
Scientists used swimming speed as a measure of cardiorespiratory fitness. Fish exposed to the highest levels of oil swam slowest, likely making them easier targets for predators. He compared the damaged herring to infant children born with heart defects.
"The child doesn't grow well. It's called 'failure to thrive,'" a condition that can be corrected by a heart surgeon.
"That doesn't happen with fish," he said.
According to water samples collected in Prince William Sound during the 1989 herring spawning season, 98 percent of the samples had oil concentrations above the level that caused heart development problems among herring in the study. Juvenile salmon with heart defects, swimming more slowly and not pumping blood as efficiently as an unharmed fish, would be more vulnerable to predators and disease. It's not much of a leap, he said, to conclude that more juvenile mortality would have an effect on how many herring survive to be spawning adults.
The findings should contribute to more accurate assessments of other spills, such as the Deepwater Horizon disaster, which replaced the Exxon Valdez spill as the largest in U.S. history.
"And not just other spills," Incardona said. "For us down here in Puget Sound, one of our big concerns is just urbanization, and the little, tiny oil spills that happen every day as non-point source pollution. Certainly for both — large spills and everyday chronic pollution from fossil fuel use — are potentially producing the same kinds of effects." |

EXTRA! EXTRA!
EPA caught covering up environmental impact of Animas River mine waste spill.
Pick your favorite news source and Read All About It!
I happened to catch it in a left wing McClatchey news release.
I hope some Republican ... ANY Republican ... turns out the lights on that obstreperous dinosaur of an agency. |

If Isobars had posted a link, he might have actually made an effort to communicate.... |

As you know, there is way more to this story than an edited video of the reaction of the EPA contractor in the field at the time of the blowout.
There is plenty of blame to go around. I find it very interesting to watch how those with special interests begin to spin the parts of the issue that meet their narrative. |

CB--true that. I would actually like to see some press coverage of the hearings. I remember a Congress that actually held hearings and solved problems. |
