A Yolo County biomass company was ordered Friday to pay a multi-million dollar penalty as result of civil settlement reached in an environmental protection action.

Woodland Biomass Power was sentenced by Yolo County Superior Court Judge Samuel McAdam to pay $4.22 million for penalties, costs and remediation.

The action was filed by district attorneys from Yolo, Solano and San Joaquin counties.

[NEWS] County-by-County Variability of Bioenergy Crop Yields in the U.S.

Using corn and soybeans as their testing ground, researchers at Pacific Northwest National Laboratory devised methods to peer into the mechanisms that modulate crop yield variability. They used statistical models to examine how climate variability impacts yields of these popular bioenergy crops at the county level. Among climate factors, the team showed that temperature is predominant in corn-growing counties, both by volume and percentage of production. Precipitation has a similar impact. The amount of energy from the sun, or radiation, has a much smaller effect USA-wide on both soybeans and corn.

[NEWS] Is Wood a Green Source of Energy? Scientists Are Divided

Drax Biomass (Daily Mail)

It took half a century for an acorn to grow into the 20-meter-tall oak tree standing here in a North Carolina hardwood forest near the banks of the Northeast Cape Fear River. But it takes just seconds to turn the oak into fuel for the furnace of a European power plant.

A logging machine—a cross between a tank and a one-armed crab—grabs the tree with a metal claw. With a screech, a spinning blade bites through the trunk. Ultimately, the thickest bits of this tree and hundreds of others from this forest will be sliced into lumber. But the limbs from large trees like this, along with entire small or crooked trees, go to a specialized mill to be squeezed into tiny wood pellets. Shipped across the Atlantic Ocean, they will likely end up fueling a giant power plant in the United Kingdom that supplies nearly 10% of the country’s electricity.

[NEWS] Dead Trees Mean New Life for Fresno, California Biomass Facility

Dead trees will continue being turned into electricity near Fresno for another five years after a biomass plant in Malaga got a contract to supply Southern California Edison.

The contract ends concerns that the facility, which employs 25 workers and has a $3.5 million annual payroll, could close soon. The plant’s contract was extended twice this year because of dead trees cut down in the Sierra.

The 24-megawatt plant was supposed to close Dec. 31 without a new contract. Utilities no longer were going to pay for electricity generation from biomass plants because the fixed price that supported the plants was expiring.

Biomass plants in Delano, Mendota, Dinuba, Terra Bella and Firebaugh have closed in recent years because of expired power purchasing agreements.

[EXCLUSIVE] Forest Service Studies Soil Impacts of Bioenergy Logging

– by Josh Schlossberg, The Biomass Monitor

A recent study from the U.S. Forest Service’s (USFS) Rocky Mountain Research Station investigates the potential impacts on forest productivity from logging for biomass energy. While the study focuses primarily on the Northern Rockies region—where only a handful of small combined heat and power and biomass heating facilities operate—many of the findings may be applied to western forests.

The study, Impact of Biomass Harvesting on Forest Soil Productivity in the Northern Rocky Mountains, by Woongsoon Jang and Christopher Keyes from the University of Montana, and Deborah Page-Dumroese with the Rocky Mountain Research Station in Moscow, Idaho, assesses one of the main environmental concerns surrounding an expansion of bioenergy, the impact on forest soil productivity.

USFS defines forest productivity as the “integration of all environmental factors encompassing soil productivity, climate, topography, geology, vegetation, and the history of natural disturbances and anthropogenic interventions.” Ultimately, the question is whether logging for bioenergy may impair future forest growth.

Logging for bioenergy involves removing more organic matter from the forest than conventional logging for lumber alone. The practice of whole-tree logging extracts not just merchantable tree trunks for lumber, but also treetops, branches, and other logging byproducts, and has a “substantial impact on live vegetation,” according to study authors.

Though whole tree logging is not typically employed in the western U.S. forests, the authors predict that forests will “likely be managed more intensively in the future,” in part for biomass energy.
