Send in all available U.S. militia to the gulf region now.

Point every boat to the region as we initiate the creation of volunteer citizen action teams.

Pursue all efforts to involve best practices and safe containment, cleaning and remediation for all stages of oil damage on all fronts, especially now as it continues to grow and before hurricane season.

Create a plan for immediate deployment from other war efforts. Pull out troops for redeploy. Get traction now.

Make this important choice to save the environment of our country and take responsibility for what has happened by declaring war on the Deepwater Horizon oil spill.

The spill and this moment in time require strategic, orchestrated, positive and focused action now!

Here’s the post from MendoCoastCurrent in the Citizen’s Briefing Book at President-elect Barack Obama’s change.gov site:

Renewable Energy Development (RED) federal task force

Immediately establish and staff a Renewable Energy Development (RED) federal task force chartered with exploring and fast-tracking the development, exploration and commercialization of environmentally-sensitive renewable energy solutions in solar, wind, wave, green-ag, et al.

At this ‘world-class incubator,’ federal energy policy development is created as cutting-edge technologies and science move swiftly from white boards and white papers to testing to refinement and implementation.

Mendocino Energy:

Renewable energy incubator and campus on the Mendocino coast exploring nascent and organic technology solutions in wind, wave, solar, green-ag, bioremediation and coastal energy, located on the 400+ acre waterfront G-P Mill site.

Mendocino Energy may be a Campus in Obama’s Renewable Energy Development (RED) federal task force.

Vision:

Mendocino Energy is located on the Mendocino coast, three plus hours north of San Francisco/Silicon Valley.  On the waterfront of Fort Bragg, a portion of the now-defunct Georgia-Pacific Mill Site shall be used for exploring best practices, cost-efficient, environmentally-sensitive renewable and sustainable energy development – wind, wave, solar, bioremediation, green-ag, among many others. The end goal is to identify and engineer optimum, commercial-scale, sustainable, renewable energy solutions.

Start-ups, universities (e.g., Stanford’s newly-funded energy institute), the federal government (RED) and the world’s greatest minds working together to create, collaborate, compete and participate in this fast-tracked exploration.

The campus is quickly constructed of green, temp-portable structures (also a green technology) on the healthiest areas of the Mill Site as in the past, this waterfront, 400+ acre created contaminated areas where mushroom bioremediation is currently being tested (one more sustainable technology requiring exploration). So, readying the site and determining best sites for solar thermal, wind turbines and mills, wave energy, etc.

ANNIE CORREAL, The New York Times, April 27, 2008

FORT BRAGG, Calif. — On a warm April evening, 90 people crowded into the cafeteria of Redwood Elementary School here to meet with representatives of the State Department of Toxic Substances Control.

The substance at issue was dioxin, a pollutant that infests the site of a former lumber mill in this town 130 miles north of San Francisco. And the method of cleanup being proposed was a novel one: mushrooms.

Mushrooms have been used in the cleaning up of oil spills, a process called bioremediation, but they have not been used to treat dioxin.

“I am going to make a heretical suggestion,” said Debra Scott, who works at a health food collective and has lived in the area for more than two decades, to whoops and cheers. “We could be the pilot study.”

Fort Bragg is in Mendocino County, a stretch of coast known for its grand seascapes, organic wineries and trailblazing politics: the county was the first in the nation to legalize medical marijuana and to ban genetically modified crops and animals.

Fort Bragg, population 7,000, never fit in here. Home to the country’s second-largest redwood mill for over a century, it was a working man’s town where the only wine tasting was at a row of smoky taverns. But change has come since the mill closed in 2002.

The town already has a Fair Trade coffee company and a raw food cooking school. The City Council is considering a ban on plastic grocery bags. And with the push for mushrooms, the town seems to have officially exchanged its grit for green.

The mill, owned by Georgia-Pacific, took up 420 acres, a space roughly half the size of Central Park, between downtown Fort Bragg and the Pacific Ocean. Among several toxic hot spots discovered here were five plots of soil with high levels of dioxin that Georgia-Pacific says were ash piles from 2001-2, when the mill burned wood from Bay Area landfills to create power and sell it to Pacific Gas & Electric.

Debate remains about how toxic dioxin is to humans, but the Department of Toxic Substances Control says there is no safe level of exposure.

Kimi Klein, a human health toxicologist with the department, said that although the dioxin on the mill site was not the most toxic dioxin out there, there was “very good evidence” that chronic exposure to dioxin caused cancer and “it is our policy to say if any chemical causes cancer there is no safe level.”

Fort Bragg must clean the dioxin-contaminated coastline this year or risk losing a $4.2 million grant from the California Coastal Conservancy for a coastal trail. Its options: haul the soil in a thousand truckloads to a landfill about 200 miles away, or bury it on site in a plastic-lined, 1.3-acre landfill.

Alarmed by the ultimatum, residents called in Paul E. Stamets, author of “Mycelium Running: How Mushrooms Can Help Save the World.”

Typically, contaminated soil is hauled off, buried or burned. Using the mushroom method, Mr. Stamets said, it is put in plots, strewn with straw and left alone with mushroom spawn. The spawn release a fine, threadlike web called mycelium that secretes enzymes “like little Pac-Mans that break down molecular bonds,” Mr. Stamets said. And presto: toxins fall apart.

In January, Mr. Stamets came down from Fungi Perfecti, his mushroom farm in Olympia, Wash. He walked the three-mile coastline at the site, winding around rocky coves on wind-swept bluffs where grass has grown over an airstrip but barely conceals the ash piles. It was “one of the most beautiful places in the world, hands down,” he said.

Quick to caution against easy remedies — “I am not a panacea for all their problems” — he said he had hope for cleaning up dioxin and other hazardous substances on the site. “The less recalcitrant toxins could be broken down within 10 years.”

At least two dioxin-degrading species of mushroom indigenous to the Northern California coast could work, he said: turkey tail and oyster mushrooms. Turkey tails have ruffled edges and are made into medicinal tea. Oyster mushrooms have domed tops and are frequently found in Asian food.

Local mushroom enthusiasts envision the site as a global center for the study of bioremediation that could even export fungi to other polluted communities.

“Eventually, it could be covered in mushrooms,” said Antonio Wuttke, who lives in neighboring Mendocino and describes his occupation as environmental landscape designer, over a cup of organic Sumatra at the Headlands Coffeehouse.

The proposal is not without critics, however.

“There still needs to be further testing on whether it works on dioxin,” said Edgardo R. Gillera, a hazardous substances scientist for the State Department of Toxic Substances Control. “There has only been a handful of tests, in labs and field studies on a much smaller scale. I need to see more studies on a larger scale to consider it a viable option.”

On April 14, at a packed City Council meeting, an environmental consultant hired by the city voiced skepticism, citing a study finding that mushrooms reduced dioxins by only 50 percent. Jonathan Shepard, a soccer coach, stood up and asked: “Why ‘only’? I think we should rephrase that. I think we should give thanks and praise to a merciful God that provided a mushroom that eats the worst possible toxin that man can create.”

Jim Tarbell, an author and something of a sociologist of the Mendocino Coast, said the enthusiasm for bioremediation showed a change in the culture at large.

“We are trying to move from the extraction economy to the restoration economy,” Mr. Tarbell said. “I think that’s a choice that a broad cross-section of the country is going to have to look at.”

At the April 14 meeting, Georgia-Pacific promised to finance a pilot project. Roger J. Hilarides, who manages cleanups for the company, offered the city at least one 10-cubic-yard bin of dioxin-laced soil and a 5-year lease on the site’s greenhouse and drying sheds for mushroom testing. And the City Council said it would approve the landfill but only if it came with bioremediation experiments.

So, sometime later this year, Mr. Stamets is scheduled to begin testing a dump truck’s load of dioxin-laced dirt in Fort Bragg.

“One bin. Ten cubic yards. That’s a beginning,” said Dave Turner, a Council member. “I have hope — I wouldn’t bet my house on it — but I have a hope we can bioremediate this.”
