Woody Biomass Use Doesn’t Have to be Controversial

This month’s theme, woody biomass, has caused quite a stir as more projects that intend to utilize the resource to produce power and heat emerge.

One of the main concerns people have about using woody biomass as a power source is that it will decimate our nation’s forests. I understand why this is a concern, but I maintain that the use of woody biomass can be sustained by concentrating on the planting of fast-growing tree species on marginal land, replanting tree stands as they are harvested, which is already being done, and focusing on wood residue that isn’t used by the wood products industry, such as insect and disease-damaged trees and forest residue that’s removed to prevent fi res.

I recently read about a great example of how a group of forest managers, the forest prod-ucts industry, environmentalists, economic developers and other interested parties in Arizona have worked together to sustainably use woody biomass from national forestlands. The White Mountain Stewardship Project, which involves the Apache and Sitgreaves National Forests in East-Central Arizona, was created to provide a long-term, reliable supply of woody biomass for the wood products industry, reduce the risk of wildfi res and stimulate the local economy, according to the article. The project, now in its fi fth year, has succeeded in maintaining and improving forest health, creating jobs, supporting the local timber industry and the economy, and producing energy. The article “Contract Brings Jobs, Energy, and Healthier Forests” by Steve Wilent was published in the December issue of The Forestry Source.

The article talks about the project, its benefi ts and the effort it took to make it successful. As you may have guessed, a lot of hard work and compromise went into this project. As with any large-scale project involving several different people and entities—all with their own agendas and goals—there are challenges and disagreements, but the fact that they could all come to some sort of agreement is something that should be celebrated. And, as one of the sources in the articles pointed out, it didn’t happen overnight. “That’s one of the bigger lessons that we try to impart to other national forests who come out here and ask how they can make this happen on their forests,” says Sue Sitko, The Nature Conservancy’s White Mountain program manager. “You can’t simply decide you’re going to implement a stewardship project and expect everything to fall in line. There has to be a lot of work up front before that happens.”

Anna Austin writes about the development and optimization of fast-growing trees for bio-energy production in her feature “Cream of the Coppice.” She also provides an outsider’s view of the Biomass Crop Assistance Program as the industry awaits defi nitions and details about how it will be administered, in the feature titled “BCAP: New and (Maybe) Improved.”

Lisa Gibson’s “Pacifi c West Profi le” feature details the myriad of biomass resources in the Pa-cifi c West that have yet to be fully tapped, including woody biomass, crop residue, animal waste, munici-pal solid waste, and food and bev-erage plant waste.

Happy New Year and happy new Congress.The 112th Congress begins its fi rst session later this

month. As all are aware, the Republicans have wrested control of the House away from the Democrats.

How will these changes in Washington affect the biomass industry?

The short answer is that things will probably change to some extent, but probably not a whole lot. Below are a few areas where we can expect to see differences from the Democratic reign. But, rest assured, the Biomass Power Association will be working closely with our team in Washington to continue to keep the biomass industry and our legislative issues front-and-center for new and old members alike.

Renewable energy standard: During the 111th Congress, many in the renewable energy sector had high hopes for the passage of a renewable energy standard, which would likely have resulted in extra incentives for renewable energy forms over more traditional forms of energy production. The Republican majority in the House may not have the same appetite for aggressive federal stimulus for the renewable sector. That said, clean energy is a bipartisan issue, so stay tuned.

Taxes: Since Republicans tend to vote heavily in fa-vor of business interests—especially small business—we are hopeful that the 1603 tax extenders will be enacted at the beginning of the new Congress (if they were not enacted during the December lame duck session). Tax extenders would give many new and existing facilities some room in the budgets for updating equipment, hir-ing extra help and many other expenses that are essential to effectively running a biomass facility. Many other renewable energy associations are similarly hopeful for a near-term 1603 passage. As this column is going to press, the fate of the production tax credit for existing facilities is very much uncertain.

Jobs: Jobs and the economy will likely take a place of prominence during the start of the new Congress. If your district elected a new member of Congress, we

urge you to write a letter of introduction to your new representative. Ideally, the purpose of your letter would be threefold: explaining what biomass energy is, listing the number of jobs that your biomass facility provides to the district’s economy and describing the many economic and environmental benefi ts of biomass energy.

As we all know, many states are taking a growing interest in our industry. The state level traditionally has been where the biomass industry fi ghts some of its most challenging battles, and we do not expect this to change. Some states, like California, have been highly supportive of biomass throughout the industry’s short existence. Others, like Massachusetts, have proven to be more dif-fi cult to win over.

As more biomass facilities are built across the coun-try, we will continue to work closely with state and local offi cials to ensure they have a good understanding of the many potential benefi ts offered by biomass.

Meanwhile, the U.S. EPA has announced a few policy changes that will positively affect the industry, either immediately or sometime in the future. It appears increasingly likely that the agency will correctly classify biomass as environmentally friendly or carbon neutral in the new year.

BCAP: Finally, there is BCAP, which remains a signifi cant program for the biomass industry. All of us will have to work hard in the coming year to make sure Congress funds BCAP at acceptable levels. While our job will be made extra challenging in this era of fi scal restraint, biomass deserves the same level of support provided to other forms of agriculture. It’s up to us to make sure that happens.

We wish each and every one of you a Happy New Year, and we look forward to working with you to continue to educate Americans and our elected offi cials about our industry.

Technologies for biobased heat and power, and the resulting economic and environmental ben-efi ts, may vary because of the regional availability of resources and needs. In Maine, for instance, the Manomet Center for Conservation Sciences has pub-lished a report that fi nds burning of whole trees for electricity production may not be as carbon neutral as once thought and that it will take 40 years for the carbon balance to catch up.

This study does, however, conclude that trees used for combined heat and power (CHP) have a much more positive effect on effi ciency and carbon balance. The Manomet study makes assumptions about the use of forest assets that can tend to make the projections less favorable for trees used for heat and power. This study is also an example of the re-gional differences in application of biomass for heat and power and the assumptions that must be made to project the effi cacy of individual biomass technolo-gies.

In contrast to Maine, the type of biomass ap-plications you would fi nd in the Central Plains states of the United States are quite different. In the Plains states, agriculture residues and energy crops would be the primary source of biomass for use in heat and power generation.

Biomass feed systems, burner retrofi ts and emis-sions control will be different for agricultural residues or energy crops compared to the use of trees.

Recent studies at the Energy & Environmen-tal Research Center have shown that cocombusting woody biomass with coal has the potential to remedi-ate some of the fouling issues in the furnace, thereby enhancing the overall plant effi ciency, but this will

depend on the type of woody biomass and the com-bustion conditions.

Cofi ring sawdust can reduce the amount of inor-ganic material or ash that will be available in the fur-nace to impact heat-transfer surfaces and reduce the cause of fouling and slagging issues, while cofi ring bark or hog fuel with inherent higher inorganic ash content may not reduce fouling and slagging issues.

For agricultural residues such as wheat straw, cofi ring can also be problematic because of very small silica phytoliths that are contained in the plant material to give rigidity. These phytoliths are an amouphous form of silica, can have low melting temperatures, and will mix with other inorganic ele-ments in the ash to produce sticky ash material that will adhere to heat-transfer surfaces reducing thermal effi ciency of the furnace. This can be overcome by adjusting the design of the furnace and the way the straw is combusted.

EERC pilot testing shows that it is imperative to match technology applications with resources to properly utilize the vast biomass resources available in the United States to offset our fossil fuel use and reduce overall carbon emissions.

In the end, smart planning, matching biomass technologies with biomass resources, and learning from the experience of others will ensure the contin-ued growth of biomass and U.S. energy security while reducing carbon emissions.

Biomass is one of the oldest energy sources, and there are compelling arguments for its use to generate electricity. First, unlike fossil fuels, the regenerative capacity of biomass provides for a renewable fuel source. Second, a signifi cant amount of viable feedstock is considered waste, the use of which serves the dual purposes of energy production and waste management. Third, the use of sustainable biomass displaces the use of fossil fuels. Though both fuel sources emit CO2, the CO2 emitted by biomass would occur any-way through the process of decomposition, so there is a net reduction in CO2 emissions. Finally, the combustion of bio-mass also reduces methane emissions associated with the naturally occurring process of decomposition.

Despite the signifi cance and potential of biomass as an energy source, development of a reliable feedstock sup-ply chain has not occurred. Developers understand that a stable, long-term feedstock agreement is essential to procur-ing fi nancing for any biomass project. Demonstrating to a landowner or farmer that the economic and other benefi ts of producing biomass (the production of which is often a multi-year commitment) outweigh the current land use can be a challenge without an established demand for the feed-stock. Current land use, such as row crops, hunting habitat or Conservation Reserve Program acres, competes with biomass crops. Creating demand for feedstock also requires construction of conversion facilities, which require fi nanc-ing in addition to the fi nancing of the generation facilities. And, in the true spirit of the chicken and the egg conun-drum, lenders and investors require a reliable, long-term feedstock source before fi nancing a project.

Prohibitively high costs are often cited as a major driver behind decisions to abandon biomass projects. Research into cost saving processes is currently underway. For ex-ample, it has been shown that denser fuel pellets offer cost savings but the drawback is that often the pelletization pro-cess results in signifi cant feedstock loss. At the same time, the storage and transportation costs of denser pellets are signifi cantly lower than other densifi cation options, such as baling. Efforts to integrate biomass with traditional agricul-ture, for example through the use of crop rotation and agri-cultural intensifi cation may lead to yield increases and price reductions. Sustainable harvesting techniques, such as one-

pass harvesting, can reduce harvest site fuel consumption signifi cantly. Further, developing synergies between harvest and transport, for example by using self-compacting wag-ons for both harvesting and transportation, may also pro-vide cost savings.

Satellite processing may save costs by allowing certain preprocessing of the biomass to occur before transporta-tion to the conversion facility. Drying and densifi cation of the feedstock with mobile equipment that can be located close to the feedstock can reduce transportation costs. The establishment of regional processing centers that aggregate, process, store and supply biomass to the region could also provide signifi cant cost reductions. In addition to drying and densifi cation, regional centers could perform other pre-processing procedures to homogenize feedstock from sev-eral sources. Developers could decrease expenses associated with having multiple feedstock contracts. The aggregator, given its size, should be able to provide a more reliable sup-ply, as a result of the large quantities it can handle.

According to the chief executive offi cers of several major biofuel companies, advanced biofuel commercial-ization is only a few years away, even though many argue that this is overly optimistic. Biomass projects will need to fi nd the right combination of the type and location of feed-stock, cost effective harvest and transportation methods and demand for output.

With an increasing number of states adopting or ex-panding their renewable portfolio standards, utilities can help drive demand for biomass projects. Often utilities as-sign more value to biomass projects because unlike wind or solar, it is base-load power. As technology evolves, we will see maturation of the supply chain through the intro-duction of satellite and regional processing facilities. These advances, in conjunction with more effective harvest tech-niques, the development of high-yield energy crops and ad-vancements in processing and conversion technology can all work to move the industry forward.

project in North America. As the world’s agricultural and waste management in-dustries seek cleaner and greener tools for curbing global warming and saving valu-able organic resources, this company has perfected heat capture from organic waste through, static, aerobic composting. The newest installation is on a dairy heifer calf raising facility near Albany, N.Y. The facil-ity maintains 2,000 head when full. The composting and heat recovery system will virtually eliminate the farm's dependence on propane, while dramatically reducing diesel, electric and grid-based energy dependence. Forty percent volume reduction will save on equipment, fuel and man-hours to fi eld apply compost.

Martin Engineering offers new conveyor cleaning blade

A new cleaning blade for use on vulcanized conveyor belts features a special polyurethane blend and tungsten carbide tip to deliver service life two to three times longer than conventional urethane blades. Designed to provide excellent cleaning per-formance immediately, avoiding any break-in period, the QCM #1 MT Pre-Cleaner from Martin Engineering maintains consis-tent tension without frequent adjustment, requiring retensioning just twice a year in most applications. The blade can be used at belt speeds up to 900 feet per minute (4.6 meters per second) and there is no

limitation to the type of material on which it can be used.

HEI unveils new AD technologyHoffl and Environmental Inc. has

introduced a unique piece of heat recovery equipment that optimizes the output of biogas from anaerobic digesters. Called the “hougulay,” it is a piece of proprietary process equipment that is used to facilitate high production of biogas. The hougulay was fi rst developed and used at HEI’s hog-manure-to-biogas-to-electricity plant located on the island of Cyprus where agricultural waste is used to generate 1 megawatt of power. The size of a hougulay, its internal design and components, its fl ow rates—both the heat and material balances across the unit—are optimized features that are esoteric to any kind of feedstock entering the plant. Critical to the design and engi-neering of the hougulay is an understanding of basic heat transfer equations including thermal transient analysis. Also, hougulay optimization depends upon knowledge (and on-line measurement) of the specifi c heat and/or heat capacities of the feedstock components.

Natural Power enters biomass industry

International renewable energy con-sultancy Natural Power recently announced the company’s move to the biomass sector, further adding to its products and ser-vices provided in the wind, wave and tidal markets. A team of professionals across the biomass and associated industries have joined Natural Power’s renewable energy ex-perts at its global headquarters in Scotland. The biomass team led by Dan Gates, who has a forestry background with engineering and project management experience, joined Natural Power earlier this year and work has already been secured including due diligence

services on a 15-megawatt biomass plant in England. Other projects range from private estates and large public sector clients to established developers who require develop-ment support across the biomass project life cycle.

Bandit-sponsored race carfinishes strong in Kansas

NASCAR nationwide sensation Parker Kligerman delivered a valiant effort at the Kansas Lottery 300, taking the Bandit Industries/GetMoreVacations.com Team 42 Dodge Charger to 24th position despite a spinout on the fi nal lap of the race. The number 66 car of Steve Wallace was the guilty party, tapping Kligerman on the fi nal lap and sending him backward into the wall. Kligerman had been running in 11th spot after fi ghting back from being a lap down. He qualifi ed seventh but fell back early on. Kligerman remained consistent through the run, holding near the end of the lead lap for most of the event.

Closing the Cottonwood LoopBiomass supply service offers a closed-loop approach to cottonwood feedstock.

Energy crops have yet to reach their full potential in the U.S., but a new dedicated woody crop supply service could help them gain popularity. It offers a closed-loop solution to a continuous supply of cottonwood feedstock, managed from start to fi nish by one company.

Virginia-based C2Invest LLC (C2I) is a project develop-ment and management company that added the supply service to its portfolio a year ago. “What we do is purely afforestation and high-density plantations,” says Page Gravely, senior director for C2I. “If you’ve got a utility looking for a dedicated, sure supply of feedstock, we go out and secure the acres and oversee the specifi c planting of those trees for a specifi c volume over a preferred long-term agreement.”

Many feedstock supply companies hand off the seed to a grower, who takes the responsibility of growing and often deliver-ing the biomass to the end user. C2I, however, is involved in the entire life cycle until it gets to the end-user's door. “Our design is to be more turnkey and full service,” says Carey Crane, a C2I founder. The company secures the land for planting, has a hand in the cutting supply, designs spacing for the plantations, and over-sees quality control of planting, growth, harvesting and delivery. “We’re not only the supplier, but the project manager, if you will, for that entire supply chain,” Crane says, adding that C2I works with landowners to secure acreage.

The crops planted currently are in Louisiana, but prime cot-tonwood growing soil is predominantly in the Mississippi Delta, beginning where the Mississippi and Ohio rivers split in Illinois and extending to the Gulf of Mexico. The regions include eastern Louisiana, eastern Arkansas, western Mississippi and western Ken-tucky. In those areas, cottonwood can grow 12 to 15 feet per year, allowing for a biennial harvest, Gravely says. “One of the natural benefi ts of cottonwood is that they coppice,” he says. “It is truly and literally a renewable tree that regrows when it’s harvested.”

Growing biomass coppice is an old practice and in Europe incentives for dedicated energy crops often surpass that of forest materials. So pellets or briquettes manufactured using such crops will bring in a higher price. “It’s a huge benefi t,” says Karl-Heinz Schulz, vice president of technology and engineering for BiEnergy Group LLC, an engineering and consulting company. “The utili-ties can pay more for the pellets than if the feedstock was from [forest-based] woody biomass.”

BiEnergy Group works with energy-from-biomass projects such as district heating and combined heat and power, but also does feasibility, construction, engineering, project development

and equipment acquisition for biomass pellet and briquette opera-tions. About 90 percent of pellet manufacturers in the U.S. ship their product to Europe, where the market is better established and incentivized, Schulz says.

C2I has no contracts in place for the supply service currently, but is in negotiations with several entities. It’s no secret that secur-ing a feedstock supply can be one of the toughest aspects of a project, especially in markets experiencing a rise in competition for material. “One of the rubs has been how do you have a security of supply?” Gravely says. “How do you have a consistent sup-ply? That’s where closed-loop really checks a lot of those boxes.” —Lisa Gibson

Invented by David Mooney of Roswell, Ga.-based REM Engineering Inc., Enginuity Energy’s Ecoremedy biomass gasifi cation system is slated for commercial deployment in the spring. This mile-stone will be reached at an energy nutrient recovery facility in Pennsylvania, following several years of development and testing.

Ecoremedy was awarded a patent in 2005, two years after initial alpha testing. Beta testing contin-ued through 2007, with advanced pilot plant opera-tions taking place at Tyson Foods Bolivar Feed Mill in Fairmount, Ga., through 2008. Since deploy-ment at Tyson, the technology has been success-fully operated at Illinois State University and other confi dential private corporations, according to Rich Madeira of Enginuity Energy.

Madeira says Ecoremedy is advanced but simple to operate and doesn’t require higher skill sets than those required to operate and maintain conventional boiler technology. Once the biomass is transferred from storage, it enters a gasifi er cham-ber and is heated on advanced conveyor technology. Gases from the heated biomass are forced upward, and hot air ignites the gas to create a fi reball that heats the boiler and creates steam. The steam is used to generate thermal energy and/or electric power generation, and the exhaust gases pass through an air heater. Ambient air is heated before being sent to the gasifi er to continuously fuel the fi reball, and before being cir-culated under the conveyor belt to heat the biomass. Exhaust goes through fi lters to separate fi ne particulates that are captured and processed as part of the recovered nutrient, which is processed and then can be used as a fertilizer, feed supplement or biochar.

Madeira emphasizes the value of the additional component of the technology besides heat and power generation—recovery of the nutrients within agricultural byproducts such as poultry lit-ter, manures, spent mushroom substrate and more. “The materials the system focuses on using as feedstocks are readily and overly abundant and possess high levels of nutrient content,” he says. “This combination offers the opportunity for no- or low-cost pro-curement of the feedstocks with a signifi cant resale value once the nutrients have been recovered via the gasifi cation process.”

In addition, the system isn’t hindered by the need for uniform size, shape or moisture content of the fuel, as it allows up to 65 percent moisture content, 80 percent ash, and varied moisture and size. The energy output varies with the material used, Madeira explains.

The smallest Ecoremedy unit can be mounted on a 53-foot fl at-bed trailer and process several hundred thousand pounds of material per hour. A 2.5 megawatt (MW) plant can be constructed on a 1-acre site, and the largest designed plant of 22 MW requires less than fi ve acres.

The 2011 business activity outlook for Enginuity seems to be healthy. “We have a 22-MW plant designed and a letter of intent on a 2.5-MW power plant that will annually convert 85,000 tons of egg laying manure into energy and recover 13,000 tons of nutrients,” Ma-deira says. During this particular installation, all of the carbon will be removed so nutrients can be recycled as an animal feed supplement. “However, the output could be regulated to increase carbon content to create a biochar product,” he says.

Recently, Enginuity constructed a new Ecoremedy research and development facility on the Harrisburg Area Community Col-lege campus in Harrisburg, Pa., that will serve to advance biomass gasifi cation testing, evaluate new materials for their application as fuel and evaluate nutrient content for use as fertilizer or feed supplement. Madeira adds that in January, Enginuity, working in conjunction with the American Mushroom Institute and the Pennsylvania Department of Agriculture, will use the Ecoremedy system to prove that spent mushroom substrate is a viable source of clean energy and recover-able nutrients. Live demonstrations will be held in conjunction with the Pennsylvania Farm Show in January. —Anna Austin

A study initiated by Greene County, N.Y., to evaluate its biomass resources and potential has found that the county could lead the state in biomass fuel production, given its vast amount of underutilized resources, location and transportation infrastructure. The study concluded that to get the ball rolling, however, public support must be built through multiple steps.

Dan Conable of study co-conductor Cato Analytics LLC says familiarizing local businesses, residential consumers and the log-ging industry with fi rewood as a source of heat, in lieu of fuel oil, would be a good starting point.

In Greene County roughly 70 percent of residences and small commercial/institutional heating comes from fuel oil, Conable says. The county has less than 50,000 people and spends about $2 million dollars monthly on imported fuel oil in the winter, he says. “For New York state, the heating oil bill comes to more than $5 billion per year.”

Since many homes and businesses are heated with fuel oil, there is a real opportunity for wood heat in Greene County—as is the case with most of the Northeast—even though petroleum prices have been depressed by the economic crisis of the past few years. Although the Btu value of wood is competitive with fuel oil, without any form of subsidy, a large barrier remains—the relatively high up-front cost of an effi cient pellet stove or two-stage wood furnace, Conable says. These units have better than 75 percent thermal effi ciency and acceptable emissions levels.

To help with up-front costs, the report recommends includ-ing biomass energy in the state’s Property Assessed Clean Energy program to set the stage for a pilot program. PACE eliminates the up-front cost for energy improvements by allowing property owners to pay for the improvements over 15 to 20 years through an increase in their annual property taxes.

Forest sustainability and harvest practices are also addressed

in the Greene County study. “One unique aspect of Cato Analyt-ics’ analysis was that it moved away from the net growth approach to modeling forest biomass availability,” Conable says. “We call that the ‘haircut approach,’— as long as you do not cut it faster than it is growing, you’ll never grow bald. The problem with that approach, as far as forests are concerned, is that it assumes that the only threat to forest health is over-cutting. In fact, the big threats to good forest management are invasive species and the pattern of har-vesting known in this part of the world as ‛high-grading.’”

Generations of over-harvesting the best hardwood species, including removal of trees at sub-optimal diameters, has left Greene County with degraded forests domi-nated by low-value trees. “In Greene County, business as usual, which is continued high-grading, might give us about 50,000 tons of low-grade wood chips harvested each year, assuming adequate local markets,” Conable says.

If landowners had the incentive to regenerate their forests by removing a signifi cant percentage of undesirable tree species, then coming back for a pre-commercial thinning 15 or 20 years later, there would be two important results, from Conable’s perspective. “For about 40 years, we would quadruple the supply of avail-able biomass, assuming regeneration cutting of 5 percent of the county’s forest every year,” he says. “After 40 years, we’d be look-ing at a forest not unlike the hardwood forests of Europe, pro-ducing a higher percentage of prime hardwood logs than we’ve been able to harvest in this country for several generations, and a much lower percentage of biomass. That would be fi ne, given the likelihood that genetic improvements will make cropped biomass a lower-cost source of lignin and cellulose than natural forest, very likely within the next 15 years.” —Anna Austin

Slightly larger than the continental U.S. with a drastically smaller population, Australia seems to offer great potential in the growth of biomass crops. At the same time, the biomass resources the country already possesses are vastly underutilized.

According to the Australian Clean Energy Council, in 2008, biomass and biogas accounted for less than 1 percent of electric-ity generation in Australia. The small fraction of biomass energy produced is mainly derived from bagasse, wood and wood waste at about 50 facilities nationwide, and nearly all of those plants are sugar production plants in Queensland. Notably, only about 50 percent of the cane biomass available for use is collected.

Aside from bagasse, Bio-energy Australia Manager Steve Schuck says wood waste is one of the most underutilized resources in the country. Bioenergy Aus-tralia is a government-industry forum, formed in 1997 to foster and facilitate the development of biomass for energy, liquid fuels and other value-added biobased products.

Interest and activity in growing new biomass crops for energy generation is coming around, Schuck says. He points out, in par-ticular, that Delta Electricity, one of Australia’s largest utilities, is embarking on an AUD $200 million project to grow oil mallee eu-calypts as an energy crop in central New South Wales. “They wish to produce energy pellets from coppiced mallee, and then cofi re at 20 percent rates at Wallerawang Power Station initially,” he says. “So far they have engaged 10 farmers, and also conducted a trial burn at this level. The units are 500 megawatts (MW), so this equates to 100 MW of biomass per unit.”

Regarding suitable, available land for growing energy crops, approximately 70 percent of Australia is desert/semi-arid land, but Schuck believes there is suffi cient land, pointing out that mallees are adapted to grow in arid conditions.

Unfortunately, there aren’t any biomass-specifi c government incentives in the country, as they generally target renewable energy, Schuck points out. “Our main driver is the Renewable Energy Target, which supports the target of 20 percent renewable energy—essentially electricity—by 2020. This requires 41,000 gigawatt hours

of new renewable electricity by that year.” Besides that market mechanism, there are few specifi c incen-

tives for bioenergy. “At a state level in New South Wales, there is an incentive for diverting wastes from landfi lls, where the mate-rial would be converted to methane,” Schuck says. “One plant, a 3-MWe digester in Sydney, takes advantage of this incentive under the New South Wales Greenhouse Gas Abatement Scheme.”

So what are some current hurdles that need to be overcome, and how does Australia compare to the U.S.? “The wholesale price of electricity has fallen by a third over the past 18 months, mainly due to a drought breaking in Queensland, freeing up cooling water for large, effi cient coal-fi red power,” Schuck says. “Also, the REC (renewable energy credit) price is volatile and depressed, due to un-intended consequences of a PV (photovoltaic) and solar hot water stimulus measure.”

The [Australian biomass] industry is probably behind the U.S., he adds, but the hurdles aren’t all that unique in comparison. “Many [hurdles] are economic and social,” Schuck says. “Issues such as food verses fuel, land use competition, and water resources will remain issues, even though I believe there is enough land for both food and fuel.” —Anna Austin

Using a torch, University of Northern British Columbia President George Iwama fi red up the school’s combined-heat-and-power (CHP) biomass gasifi cation system in November. Supplied by Nexterra Inc., the system will heat all of UNBC’s core build-ings, replace its fossil fuel usage by 85 percent—an energy savings of $800 per year—and reduce its greenhouse gas emissions by 3,500 metric tons per year.

Fuel for the gasifi er is woody biomass provided by a local family-owned sawmill, Lakeland Mills, according to Robert van Adrichem, UNBC’s vice president of external relations.

The gasifi er is currently running intermittently for testing, and a grand opening will be held in mid-March.

The CHP system and a small pellet plant on campus are part of UNBC’s Bioenergy Center for Innovation. “It’s an idea to connect the university, students and researchers to the bioenergy industry, economic development organizations and the govern-ment to determine what the ingredients are to make this viable, economic and sustainable industry of value to this community, region, province and country,” van Adrichem says.

The pellets produced in the facility are used to heat the campus’s forestry lab. “We use them to heat a building that’s grow-ing trees and doing forest research, and then using that product to heat the building,” van Adrichem says. “Initial work was on analyzing the difference between using wood pellets verses natural gas, which is what we’ve used for fuel to date on campus, and some other research projects there now are related to emissions and the use of ash as a soil additive.”

These projects are being done primarily because bioenergy is emerging as a signifi cant industry in the region, according to van Adrichem. “Because bioenergy has never been a big part of

the forest industry here—we’re a world leader in lumber produc-tion—it’s a whole new thing,” he says. “This program provides a new opportunity for the university to work with the community, region and forest industry on fundamental questions surrounding bioenergy—not just ‘who is going to buy my pellets when I make them,’ but a look at more foundational questions around forest land base sustainability, emissions, moisture content and energy performance.”

UNBC hopes to use the biomass gasifi er and the pellet plant as showcases for the local industry, as well as platforms for ap-plied research and education. —Anna Austin

The cost of using propane to fuel a grain dryer can be astronom-ical for farmers and grain elevators, especially if the dryers are run-ning 24 hours a day in the fall, which is often the case. A Bismarck, N.D., furnace company says its biomass retrofi t can slash that cost by 90 percent. Not only that, but the system’s heat recovery application is essentially 100 percent effi cient, according to the company.

“What we’ve done is displaced the propane burner with a combined system and heat exchanger that blows hot air the same way, but doesn’t use super expensive fuel,” says King Coal Furnace Corp. President and CEO Mike Robb. Farmers can use the residues and waste products from their crops, such as sunfl ower screenings, soybean trash and spent grain, to fuel the biomass burner.

King Coal can build portable systems between 1 million Btu (MMBtu) and 10 MMBtu, and on-site systems up to 50 MMBtu. Robb declined to release a cost for the dryers, but said the company is currently building two for seed company locations in Minnesota and South Dakota.

With propane costs at $1.50 per gallon, those operations can spend up to $16.50 per MMBtu, whereas sunfl ower screenings at current prices of $30 per ton and 9,000 Btu per pound, would mean a cost of only $1.65 per MMBtu, Robb says. “That’s a 90 percent reduction,” he says.

The cost is only one advantage. “The real neat thing about this is this system does not have a chimney,” Robb says. It takes gases through a proprietary dust collection system and then redirects it back into the furnace. “So the million or so Btus that would be wasted up the chimney go right back into the drying process,” he emphasizes.

“Essentially, we’ve developed a 100 percent effi cient heat recovery system.”

King Coal has a 2 MMBtu prototype at its Bismarck location to demonstrate the system’s function. The company has been building coal-fi red air heaters for years with the same type of technology.

The modular, self-cleaning and automated system leaves only the responsibility of loading the fuel bin to the operator. Robb expects the fi rst installation to be ready in Minnesota next year. —Lisa Gibson

Drying Crops with Crop ResiduesKing Coal says its biomass burner can replace propane in grain dryers and save cash.

COST-CUTTING DRYER: North Dakota-based King Coal has built a prototype of its biomass burner that burns crop residue instead of costly propane.

Envio Energi LLC had six biomass power plant projects in the works when the U.S. EPA’s proposed Industrial Boiler Maximum Achievable Control Technology (IB MACT) rule was released. Then everything came to a screeching halt, says CEO Roland Fjallstrom. Now, he's unsure of the fate of those projects and his business.

Fjallstrom, born and raised in Sweden, is a pioneer of biomass combined-heat-and-power systems and has worked in the forest products industry most of his life. In 2009, he obtained a license from KMW Energi, the largest supplier of wood bioenergy plants in Sweden and expanded into the U.S. market.

Fjallstrom, also a wood chemist, has been compiling carbon footprint data (see chart) since the IB MACT proposed rule release. His research included turning to the EU Commission for clarifi cation on its modeling for carbon footprints, which utilizes the ISO 14000 ac-credited Life Cycle Assessment. This is a method that’s used to analyze the cumulative environmental impact of a process or product through all stages of its life, from equipment manufacturing to construction to operation and maintenence.

Fjallstrom also acquired data from a study done by the British government in 2006 and updated its harvesting information. “A big portion of carbon footprint calculations is the physical harvesting,” he says. “What they’ve done with modern machines today is about half of what it used to be in 2005 and 2006. This needs to be displayed to the public and the U.S., at least within this industry, because the EPA’s cur-rent approach is ridiculous.”

The ISO certifi cation of various biomass LCA methods is well-established in Europe, Fjallstrom says. “The biogenic carbon cycle of woody biomass proves that it consumes and absorbs more carbon dioxide in its life cycle than it would ever emit in a reasonable combus-tion process. It is carbon neutral, if not carbon negative.”

“I’ve gone through GHG life cycles many times, and now I’m seeing studies that more or less suggest that [the U.S.] cannot use the science the Europeans have used over the past 50 years, rather we must reinvent it,” Fjallstrom adds. “An individual biomass source consumes and absorbs more CO2 in its life cycle than it will ever emit. There can be no re-sciencing of that—it has already been proven.” —Anna Austin

Northern Maine has about $6 million in Recovery Act fund-ing that will go toward six different biomass boiler installations. In light of the volume of current projects, the Mobilize Northern Maine Biomass Action Team for Wood Supply organized a tour in early December of four biomass-related facilities, to not only di-rect agencies already committed to installing biomass boilers, but also to inform and educate any that might still be on the fence.

Tour stops included a Seven Islands Land Co. chipping operation near Ashland; Boralex Inc.’s wood-fi red Ashland Power Station; a Maine Woods Co. sawmill in Portage Lake; and Northeast Pellets in Ashland. About 35 people took advantage of the free tour opportunity, exceeding organizers’ expectations of 25. “It generated a lot more interest than we expected,” says Bill Greaves, member of the action team and a Forest Protection Division Northern Regional ranger for the Maine Forest Service, which administers the Recovery Act funding. Attendees repre-senting organizations that received project grants included school superintendents, university presidents, hospital managers and even custodians who will be operating the boilers once installed, he says.

“They had a lot of questions about what kind of fuel they need for these boilers,” he recalls. “They were able to talk with engineers who were installing the boilers and designing the boiler systems. And they were able to talk to the fuel providers.” At the Seven Islands stop, participants learned from a forester how the biomass material is harvested, chipped and sold. Another destina-tion, Maine Woods, has a biomass boiler at its sawmill so manager Don Tardie was able to speak to tour attendees about both mill and biomass boiler operations.

The Mobilize Northern Maine Initiative, the action team’s parent group, aims to convert 4,500 households to biomass heat

by 2015. The initiative also hopes to see 10 commercial establish-ments convert, and is well on its way at nine.

The Mobilize Maine Initiative is statewide, but split into six regions and only the northern and eastern groups have begun to roll out their strategies. The program, which was announced by Gov. John Baldacci and supporting agencies in April 2009, is designed to spur community and economic development after a decline over the past decade in traditional manufacturing and commodity-based industries. “The idea is for the six regions in Maine to embrace this initiative and go about implementing Mo-bilize Maine in each of their regions,” says Walter Elish, president and CEO of the Aroostook (County) Partnership for Progress, the lead agency for Mobilize Northern Maine. —Lisa Gibson

The Oregon Biomass Producer or Collector Tax Credit program was passed in 2007 and administered by the State Depart-ment of Revenue to incentivize biomass supply options for the state’s rapid renew-able energy development. In 2009, however, administration of the law was passed to the Oregon Department of Energy, requir-ing the credits be certifi ed and mandating changes to the program.

After input from industry stakehold-ers and the public, the state DOE released its fi nal certifi cation rules Nov. 2, outlining eligibility and the application process. “So our rules are really designed to administer the certifi cation program and they describe how to apply for the tax credits, what type of documentation there is and how the department will act on those,” says Matt Krumenauer, senior policy analyst for the Oregon DOE. “The change in the certifi ca-tion program was driven partly by industry request and partly by the Department of Revenue because one of the features of this program is that the tax credits are transfer-rable.”

The credit offers $10 per green ton of eligible biomass to be used in energy gen-eration and Krumenauer says it has done its duty in spurring biomass production. “It’s been quite a popular program, primarily

on the woody biomass side,” he says. “We put some criteria in there to target more effi cient uses of woody biomass in particu-lar.” Those criteria include a cogeneration effi ciency standard of 40 percent. Eligible applicants are agricultural producers or bio-mass collectors; have a title to the biomass at the time it is delivered to the bioenergy producer; produce or collect the biomass in Oregon, directly or indirectly and including through agents or employees; and deliver or facilitate delivery of the biomass to be used as biofuel or to produce biofuel in the state. The rules apply to tax years beginning on or after Jan 1, 2010, and before Jan. 1, 2012.

The state started the rule-making process in December 2009 with committee meetings of stakeholders, and released tem-porary rules in July. “The temporary rules allow us to administer the program, learn from it, fi nd out exactly how it works for us, and how it works for our stakeholders and customers,” Krumenauer says. The fi nal rules released in November had only minor changes from the temporary ones, he added.

The program is designed to promote anaerobic digestion, biofuel production, and electricity and heat generation, Krumenauer says, adding that thus far, the credits have been used mainly by those supplying bio-mass for power and thermal applications.

In the past three years since the credit was implemented, numerous companies devoted solely to the removal of forest residues have cropped up in the state. “So I think it has gone to support job growth, es-pecially in rural areas,” he says. —Lisa Gibson

The BioBusiness Alliance of Min-nesota has released a paper with four recommendations designed to ensure long-term availability of forest biomass, foster development of new markets and maintain logging industries.

The state’s forest products indus-tries have not been immune to the global economic downturn and three of its fi ve oriented strand board mills have shut down since 2007, dropping wood consumption by 20 percent, or 1 million tons. That brings the state’s surplus to 3.2 million green tons, according to the paper, “Minnesota’s Forest Biomass Val-ue Chain: A System Dynamics Analysis.” “We’re at a point where a lot of wood isn’t being used,” says Tim Welle, Bio-Business Alliance of Minnesota project manager. “We need industries to come in and use that so there’s an incentive to continue to manage the forests.”

Forest management is a prerequisite for successful long-term growth in any forest-based industry, so the fi rst recom-mendation is to rely on it, as well as in-creased utilization, to ensure a long-term supply of raw materials. Underutilization

of the forests is threatening the state’s logging infrastructure, the paper says.

The second recommendation is to support effi cient utilization of that for-est wood for heat and power generation, which would also help develop markets for the timber industry. The alliance recommends changes to existing policy tools, including an expansion of the Conservation Improvement Program to include credit for biomass-fi red com-bined-heat-and-power facilities. The pro-gram mandates utilities meet an ongoing annual 1.5 percent energy savings, but Welle says it’s getting harder and harder for them to meet that standard year after year. The recommendation also states that tax credits for expenditures on wood energy equipment should be comparable to tax credits for other types of renew-able technologies. In 2009, the state had 41 facilities using wood for heat and electricity, some cofi ring, for a total con-sumption of 1.8 million green tons.

“Recommendations one and two are to keep loggers working to keep the infrastructure that we have today and really maintain it so that we can continue

to manage forestry and can continue to rely on our forests for our economy,” Welle says.

The other two recommendations focus on the state’s next-generation high-value opportunities that can serve as the bellweather of the economy for the next 100 years. “We’re really trying to grow the pie,” Welle says. Recom-mendation three is to actively pursue emerging high-value opportunities such as advanced biofuels and biochemicals that can sustain themselves in the longer term. And recommendation four is to foster cooperation in the implementation of all the recommendations. “Enormous potential exists if Minnesota can manage its forest biomass supply chain in such a way that creates opportunity for both traditional and emerging forest-based industries,” the paper states.

“The quick story we want to tell is the forest is in a position that we need to act now to keep our communities vibrant, to make sure that we have the employment infrastructure to have a healthy forest-based economy in Minne-sota,” Welle says. —Lisa Gibson

Biobased Bounce Back Group recommends Minnesota maintain its logging infrastructure and grow its forest-based products industry.

The Pacifi c West is known for its abundant woody biomass, but numerous other resources hold opportunities and enormous potential. The scale of development varies greatly, however, from state to state.BY LISA GIBSON

Pacific West Biomass Profile

Biomass potential in the Pacifi c West goes far beyond the well-known forestry resources. From urban wood waste to dairy manure and agricultural waste, the Pacifi c states

of Nevada, Oregon, Idaho, Washington and California have a lot to offer.

But even with such vast opportunities, development has been slower in some states than in others because of complica-tions such as the lack of forest products industries, the need for a centralized biomass collection system, or the absence of a market for the biomass material.

Nevada Needs Infrastructure Nevada is no stranger to such barriers. It is home to about

9 million acres of juniper and pinyon trees that are susceptible to extensive forest fi res, drought and climate change, according to Dusty Moller, wood utilization manager for the Small Busi-ness Development Center at the University of Nevada, Reno.

“It’s an extremely serious condition,” Moller says of the risk that he calls a climax envi-ronmental situation. “Something really needs to be done.” The state is in desperate straits, he says, because it never had a primary wood products industry that would have allowed for the processing and removal of biomass mate-rial from forests. “When you don’t have that lumber product to pay for that equipment and pay those wages, you really have a problem,” he emphasizes.

In addition to its forest resources, the state also could make use of the tremendous volume of urban wood waste that is landfi lled each year. In Clark County alone, home of the Las Vegas strip, more than 230,000 tons of urban wood waste is buried annually, Moller says.

But Nevada has not seen the develop-ment boom it can support with such extensive resources and only has one operating biomass facility: a combined-heat-and-power (CHP) plant located at the White Pine County School District in Ely, part of the U.S. Forest Service Fuels for Schools program. “It’s a chicken-and-egg kind of thing,” Moller says, adding that agencies are working together to establish a framework for biomass use. He says the pin-yon and juniper plots could provide around 6 tons of biomass per acre at a cost of about $300 per acre, but without a market, that mate-rial gets burned or chipped and applied back

to the land. “You can put a little bit back, but in the desert, you’ll come back 20 years later and it will still be sitting there because without water, it won’t decompose,” he says.

Plenty of scenarios could jump-start Ne-vada’s biomass industry, currently in limbo, and be included in the equation to help the state reach its renewable portfolio standard (RPS) of 25 percent by 2025. “If we had a CHP plant or if coal-fi red power plants would get onboard and start cofi ring coal with this avail-able biomass, then you could start to develop some markets,” Moller explains. “If we had a market, if the coal-fi red people would cofi re, if we could increase the Fuels for Schools projects, if we could get a biomass power gen-erator, then we could have a market that would be a pull situation. So we can pull that biomass off that land. Once you get that started, it’s just kind of like a sustainable, stable industry.”

Oregon Offers IncentivesOn the opposite end of the spectrum sits

Oregon, with its 14 operational wood-fi red CHP plants collectively making use of between 3 million and 4 million tons of woody biomass per year, according to Matt Krumenauer, senior policy analyst for the Oregon Department of Energy. It should come as no surprise that the state makes use of its abundant forest biomass resources and Krumenauer says the existing sawmill industry has been crucial to biomass

development. Two-thirds to three-fourths of woody biomass used currently in Oregon is mill residuals. In fact, most of the biomass facilities are at lumber or sawmill operations, with the exception of one independent plant in the southern part of the state that generates only electricity. “It certainly is a resource we’re going to explore and try to utilize much more of,” Krumenauer says. “We do have a number of projects either under construction, in devel-opment, or in operation in the state.”

A study commissioned by the Oregon Forest Research Institute found that treatment of about 4.25 million acres, 15 percent of the state’s forestland, would provide about 20 mil-lion bone-dry tons, with an additional 1 million annually for the next 20 years, not including merchantable saw timber. About 29 percent of the 4.25 million eligible acres are privately owned, the rest dominantly federal. Other than fuel treatment of overstocked forestlands, the largest source of forest biomass is 3.6 million acres of juniper in 14 eastern counties. Urban wood waste is another biomass resource avail-able for use in the state, as citizens discarded more than 500,000 tons in 2004, according to the state DOE.

But like other Pacifi c West states, woody biomass does not represent the only biomass opportunity in Oregon. In 2004, Oregonians disposed of about 3 million tons of munici-pal solid waste (MSW), 70 percent of which

Page 29: Biomass Power & Thermal - January 2011

JANUARY 2011 | BIOMASS POWER & THERMAL 29

could have been used for energy generation, according to the state DOE. Oregon also sup-ports biogas operations at wastewater treat-ment plants that generate heat or electricity. Still, the DOE estimates that about 36 percent of the biogas produced at wastewater treat-ment facilities is unused. In addition, biogas from more than 100 dairy farms large enough to install digesters could produce about 13 megawatts (MW) of electricity if used to its full potential.

Oregon also has a well-established grass seed industry, freeing up tremendous amounts of grass straw residue. The state DOE es-timates that in 2003, a total of 1.5 million bone-dry tons of material was available from farming operations and capable of producing about 213 MW. “We’re fi nding ways to use that either in digesters or in pellets or in etha-nol production,” Krumenauer says.

Oregon offers a number of incentives for renewable energy generation including tax credits for the production and collection of biomass material for use in bioenergy or bio-fuels. The program offers $10 per green ton of biomass material and helps reduce open burning while helping leverage forest steward-ship work, Krumenauer says. “It’s been quite a popular program, primarily on the woody biomass side.”

With such incentives and an existing framework boosting so many projects, Or-

egon seems to be well on its way to reaching its RPS of 25 percent by 2025 for larger utili-ties and between 5 and 10 percent for smaller

ones. Idaho Eyes Dairy Waste

U.S., Idaho has made a push to utilize waste materials and has fi ve operating dairy digest-ers. “We’re a huge dairy state,” says John Crockett, senior energy specialist for the Ida-ho Offi ce of Energy Resources. “There’s a huge potential there.” Idaho is home to more than 600,000 dairy animals and about 70 per-cent of them, along with 126 of the largest farms, reside in the south-central portion of the state dubbed the Magic Valley, according to an Idaho Strategic Energy Alliance Task Force report. The report estimates that the Magic Valley alone could produce more than 34 billion Btu per day from dairy waste.

As in most populated areas, MSW could serve as another resource for bioenergy and the task force report estimates about 1.08 million pounds were discarded in 2006. That volume could produce enough landfi ll gas to generate about 1,482 MW and power about 120 homes. The state supports two landfi ll gas-to-energy projects and has identifi ed 49 food and beverage facilities that are candi-dates for anaerobic digestion. Eight already employ the process to treat wastewater, yield-ing a total annual energy production value of

542 billion Btu and accounting for 39 percent of the biogas potential from the entire 49, the report says.

Still, Idaho is experiencing an increased interest in woody biomass utilization and al-ready has three wood-fi red power plants, with another on the verge of securing a power purchase agreement, Crockett says. “Our big-gest resource is wood,” he says. According to task force reports, the state’s forest biomass, including thinning and residues, amounts to about 1.3 million dry tons annually, enough to generate about 130 MW. The report points out, however, that the material is at logging sites and would need to be harvested and transported.

The report recommends the state help spur development of woody biomass facili-ties through creation of a business tax credit, expansion of the Fuels for Schools program, creation of a biomass removal incentive, an increase in Forest Service funding for forest restoration, a change in the federal defi nition of biomass, and an increase in community support. Idaho is also the sole Pacifi c West state without an RPS.

In addition, Idaho is home to a number of citizen working groups pushing for the use of the available woody materials, Crockett says, including one that spans four counties, another in the central part of the state and one in the north. “We’re hoping to try to get those groups working together if we can,” he says.

Washington Wipes Out WasteSuch teamwork is almost perfected in

Washington, where many state agencies are forging ahead with strategies aimed at increas-ing biomass use. The most recent biomass in-ventory for the state found it produces about 16.4 million tons of underutilized dry equiva-lent biomass each year, capable of producing more than 1,700 MW, about 50 percent of an-nual residential electricity consumption. Not surprisingly, forestry makes up 49 percent of that total, but is complemented by crop resi-dues, animal waste, food processing residues and municipal wastes. “What we’ve demon-strated is there’s a lot of material out there, but what we also know is it’s not really orga-nized,” says Mark Fuchs of the Washington

Department of Ecology Waste 2 Resources program and author of the report, “Biomass Inventory and Bioenergy Assessment: An Evaluation of Organic Material Resources for Bioenergy Production in Washington State.” “This industry is ripe for entities to come in and organize.”

Work is being done to collect broadly dis-tributed feedstocks at centralized locations, he says, but that chore is just beginning. Fuchs' assessment does not put an economic factor on collection of biomass material and roughly one-third of it already goes through some sort of system and would need further refi ning to recover energy nutrients, he says. The state is now home to 13 signifi cantly sized wood-fi red facilities, 12 of which are CHP, according to Peter Moulton, senior energy policy specialist for the state Department of Commerce.

Following forestry, municipal waste ac-counts for 24 percent of the 16.4 million tons; fi eld residues come next at 14 percent; and ani-mal waste represents 11 percent, according to the report. Fuchs makes note of the fact that a 2005 study by the U.S. DOE and USDA, “Bio-mass as Feedstock for a Bioenergy and Bio-

products Industry: The Technical Feasibility of a Billion-Ton Annual Supply,” also known as the Billon-Ton Report, seems to have under-estimated Washington’s organic material avail-ability at 9 million tons. “We think we’re closer to 16 million,” he says. “That’s a 76 percent increase.” He adds that reports due out in the next few months will likely fi nd even more bio-mass material potential.

To help utilize all that tonnage, the Waste 2 Resources program has established the Be-yond Waste plan, which has a 30-year vision of transitioning to a society that views waste as in-effi cient and where most wastes and toxic sub-stances have been eliminated, Fuchs says. The state also has an RPS of 15 percent by 2020.

recent inventory found that biomass in the state totaled 83 million gross bone dry tons in 2007, and is expected to increase to 98 mil-lion by 2020, according to “An Assessment of Biomass Resources in California, 2007.” The report specifi es, though, that technically sustainable resources, which amounted to 32 million bone dry tons in 2007, are expected to increase to 40 million in 2020. The current technical potential includes 8 million tons in agriculture, 14 million from forestry and 9 million tons from MSW excluding waste in landfi lls and biomass in sewage. Dedicated crops are being grown mostly on an experi-mental basis and are not included in the total for 2007, the report clarifi es.

Gross electrical generation potential from biomass in 2007 was near 9,500 MWe with more than 1,900 MWe from agriculture, 3,500 from forestry and 3,900 from MSW including landfi ll and sewage digester gas. Technical generating potential is closer to 3,820 MWe. A gross capacity of 985 MW could be reached collectively in California from about 30 existing solid fuel combustion facilities, 60 landfi ll-gas-to-energy systems,

20 wastewater treatment plants, and 22 ani-mal and food waste digesters, according to research by Rob Williams, development engi-neer for the University of California, Davis’ California Biomass Collaborative. Roughly 5,000 gigawatt hours per year are produced through direct combustion of about 5 mil-lion bone dry tons of solid fuels such as for-est biomass, urban wood, agricultural and food processing materials, and MSW, he adds. Landfi ll gas, wastewater digester gas and manure digesters produce another 2,600 gigawatt hours or so per year.

But expansion of biogas from manure development has come to a halt because of a limit of 9 parts per million on nitrogen oxide emissions by the state Air Resources Board, according to Mark Jenner, plant sci-ences analyst at UC Davis and member of the California Biomass Collaborative.

Policies and standards could be a bar-rier in the way of other biomass plant devel-opment, too. “The debate over moving the build up of fuel out of the forests to prevent wild fi res versus leaving it within the forest to preserve habitat and reduce disturbance is

as active in California as it is anywhere else,” Jenner says. “Wildfi res destroy thousands of acres each year and are expensive to fi ght. They destroy lots of resources and emit lots of particulate matter, VOCs (volatile organic compounds) and CO2 (carbon dioxide). Bio-fuels and biopower could serve as potential drivers to pay for the removal, but the poli-cies need to be coordinated before that can happen.”

Resources in the Pacifi c West are by no means in short supply and such policy analy-sis and change could mean a better environ-ment for their use in bioenergy development.

USDA made signifi cant changes to the Biomass Crop Assistance Program in its fi nal rule, many involving woody biomass utilization, but the jury is still out on how the changes will be implemented. BY ANNA AUSTIN

BCAP: New and (Maybe) Improved

Page 36: Biomass Power & Thermal - January 2011

Critics of USDA’s Biomass Crop As-sistance Program, a federal program designed to jump-start the use of

biomass for bioenergy production, caught the attention of USDA offi cials when they questioned whether certain woody biomass should be included as eligible material in the program.

Their criticism proved to be true when, after the original Notice of Funding Avail-ability in April 2009, some woody biomass suppliers sold their materials to eligible biomass-based heat, power, fuel or chemical producers allowing them to receive matching BCAP payments, rather than selling to their traditional customers. In most cases, that led to higher prices for customers who weren’t eligible to participate in BCAP, such as parti-cleboard makers, and therefore distorted es-tablished markets. This caused a suspension of the program so the federal agency could make necessary modifi cations.

Anna Dirkswager, biomass program coordinator for the Minnesota Depart-ment of Natural Resources Forestry Di-

vision, said that that particular loophole defi nitely affected Minnesota, which has 16.7 million acres of forestland. “With a strong forest products industry in Minne-sota, there were a lot of folks upset with round wood or whole trees being chipped and going to combined-heat-and-power facilities, because those materials were eligible,” she says. "In some areas where we have collapsed markets, we would like to see those trees cut, the forests man-aged and that material indeed being used as biomass," she says.

Though initial BCAP rules many not have been crafted as meticulously as they could have been, the USDA has altered them with the intent to safeguard materi-als already being used. At the same time, the door has been left open for qualifi -cation of residuals with no local higher value market while endorsing responsible forest management/thinning practices.

USDA has not yet determined who will decide whether there is a local, high-er-value market for some wood material.

The job may be handed to foresters or Farm Service Agency personnel. While FSA agents know their way around corn and soybean fi elds, there are concerns that they may not have enough knowl-edge about wood markets to make these determinations. Dirkswager says she doesn’t think the majority of FSA agents have a particularly good understanding of wood markets, but she is hopeful that FSA will work with her and other state offi cials, and the forest products industry, to determine certain program details such as what constitutes an acceptable Forest Stewardship Plan.

Making a Plan The 2008 Farm Bill defi nes a For-

est Stewardship Plan as a site-specifi c plan that addresses one or more resource concerns on land where forestry-related conservation activities or practices will be planned and applied.

The plan must be prepared by a for-ester with a bachelor’s degree in forest

proved, funded and scheduled, it only takes him about two weeks from beginning the fi eldwork to preparing the completed plan. The cost will depend on the tract size and the ownership objectives. “As a rule of thumb, it’s safe to say that rates run about $8 to $12 per acre with a minimum fee of $600,” Schatski says.

He says he expects his workload to in-crease moderately when the BCAP is fully implemented. “My expectation is we’ll still

be managing the same base resource, but we’ll be looking at capitalizing on harvest residues that currently have no good mar-ket,” he says.

The verdict is still out, however, on what constitutes an acceptable plan, as well as what defi nes a higher value mar-ket. “We’re trying to be proactive here in Minnesota and work with FSA to sug-gest how it might defi ne these and several other program defi nitions that haven’t

BCAP Basics

BCAP is designed to support the establish-ment and production of biomass crops for conversion to bioenergy in selected areas, and to assist agricultural and forest landowners and operators in supplying eligible material to biomass conversion facilities.

Collection, harvest, storage and transport payments: CHST payments are the fi rst of two different types of fi nancial assistance BCAP offers, providing matching payments to eligible biomass material owners (EMOs) in the amount of $1 per $1 paid per ton up to $45 per dry ton delivered to a qualifi ed biomass conversion facility (BCF), for a time limit of two years after the fi rst payment is made. An EMO is a producer of an eligible crop, or a person or entity with the legal right to collect or harvest the eligible material; a BCF is a facility that will use the material to produce power, heat, biobased products, advanced biofuels or any combination.

Establishment/annual payments: The second funding component of BCAP covers up to 75 percent of the costs of establishing and producing a biomass crop. Biomass produc-ers in BCAP project areas can receive annual payments for fi ve to 10 years, depending on the crop.

yet been defi ned,” Dirkswager says. “For higher value markets, is it going to be from the logger’s home area of residence, or is it a procurement radii? Wood chips are eli-gible only without an existing higher value market and when a result of an ecosystem restoration service, but we don’t know what ecosystem restoration will be defi ned as. We’ve got a variety of things we would like to suggest, but it is diffi cult to have a go-to person to make these suggestions to.”

Once a Forest Stewardship Plan has been established, it’s important to note that eligible woody material must be di-rectly harvested or collected from the land, meaning it cannot be collected or harvested after transport and delivery, nor collected or harvested by separating from that of a higher value material in order to be used for heat, power, biobased products

or biofuels. If the material comes from outside of a BCAP project area, it must be a byproduct of preventive treatments to reduce hazardous fuels, to reduce or contain disease or insect infestation, or for ecosystem restoration.

Tom Kimmerer, senior scientist at Moore Ventures and a BCAP specialist, gives the following example: A logging contractor runs a fl ail de-barker in the woods, which strips off bark and chips the wood for pulp. The bark can be deliv-ered to a biomass facility and it will be eli-gible for matching payments. However, if there is an established market in the area for bark, such as bark mulch, the bark may not be eligible; that’s up to the discretion of the local FSA offi ce. If that same log-ging contractor delivers whole trees to a paper mill, which strips the bark off and chips the wood for pulp, the bark can be delivered to a biomass facility but will not be eligible for matching payments.

Along with the changes made to the woody biomass eligible materials, there were also modifi cations to the annual pay-ment component of BCAP that were not implemented with the original NOFA.

More ChangesAnnual payments are now paid on

a tiered model based on the end-use of the material, a component that favors cellulosic ethanol and advanced biofu-els over biopower or bioheat. Upon sale of the crop, if used for heat, power or biobased products, payment is reduced by 40 percent, compared to a 1 percent reduction for cellulosic ethanol and 10 percent for advanced biofuels. “These payments [for biopower/bioheat] are still signifi cant, but one reason for incentiviz-ing advanced biofuels may be because un-der the [renewable fuel standard 2] there’s an aggressive congressional mandate for advanced biofuels and so far, we’re well short,” says Gregory Lynch, managing partner with Michael Best & Friedrich LLP. “The [U.S.] EPA has been lowering that over the past couple of years by a

start looking at planning how they can take advantage of BCAP.”

In order to ensure that all program par-ticipants are in compliance with the modi-fi ed or new rules, everyone must apply, even those who had previously qualifi ed and were already receiving matching collection, har-vest and storage payments.

Though the necessary federal notices have yet to be issued, Lynch says some ad-ditional clarifi cation can be expected soon. “Sometime later this month USDA plans to issue additional guidance in what they’ll look for in establishing BCAP designated project areas, and they’re looking at doing a fairly aggressive education program for industry participants,” he says. “The fi rst tentative meetings will be held in early January, and USDA will give presentations on interpret-ing the new BCAP rules, as well as provid-

ing guidance to interested parties on how to certify project areas.”

BCAP’s past trial-and-error period and collaboration with experienced and relevant state agencies could result in a well-crafted, successful program. Dirkswager says her department has already been working with Minnesota’s FSA on BCAP-related issues. “The [USDA] was able to work with us in being able to get some of the systematic hurdles resolved, but I think the creation of the fi nal rules was a polite way of writing off the forest products industry,” she adds. “But perhaps a necessary one, with the mar-ket diversion it was creating.”

fairly signifi cant amount, and I think this is one of the policy tools USDA is using to try to promote that.”

Related-party transactions, if in accor-dance with USDA defi nitions, are also al-lowed, meaning that a group or party can be both the eligible material owner and the biomass conversion facility, which would include closed-loop bioenergy production models. Additionally, several new feed-stocks were added to the eligible materials list, including algae, jatropha, energy cane and pongamia.

While the industry waits for clarifi ca-tion of the new rules, an old concern is still swirling that BCAP funding demands will be much higher than anticipated, and that some eligible participants may miss out. “If ecosystem restoration is considered a thin-ning or something that’s restoring forest health and quality, that’s a great opportu-nity to subsidize work we’d normally have a hard time paying for,” Dirkswager says. “But given that $430 million is allocated for fi scal 2011 and only $130 million of that pot is available for the matching payment portion nationwide, we have concerns over how much of that money will actually reach Minnesota. Many of the necessary program pieces that must come together to receive funding are not yet in place and I fear that we’ll get ready and it’ll be gone. If we did actually get matching payments funds, there are good opportunities to subsidize forest management work.”

A signifi cant majority of the $243 million in matching payments already dis-tributed or committed under the original NOFA went to woody resources. “[Forest-ers] are all curious about how it will ulti-mately shake out,” Schatzski adds. “Last year's experience indicated that there was signifi cantly more demand for BCAP fund-ing than was originally thought.”

Now is a unique time for BCAP, as in the past 18 months there’s been a lot of stopping and starting, Lynch says. “But the next 30 to 60 days is really the time that companies, especially wood producers or pulp and paper companies should seriously

Hybrid poplar, willow and eucalyptus are highly adaptable, fast-growing and easy to regenerate, but will landowners grow them if they can’t reap instant rewards? BY ANNA AUSTIN

Cream of the Coppice

A healthy, harvest-ready stand of hybrid poplar can yield four to 10 tons of biomass per acre annually. Each tree is capable of growing more than 60 feet in six seasons, with little maintenance beyond the

fi rst planting year. Though short-rotation trees such as poplar, willow and eucalyptus already possess impressive growth characteristics, researchers are working to optimize them as the potential for their use as bioenergy feedstock materializes.

Timothy Volk, who leads State University of New York’s short-rotation woody crops program, and his team are concentrating their ef-forts on willow, mainly because disease issues associated with poplar in the Northeast have limited its use there. Research at SUNY has included breeding, optimum plant spacing, nutrient requirements, rotation lengths and other crop management issues in and beyond the region, in order to test the trees across a broad range of conditions.

Growing WillowThe main impetus behind willow research is to determine how to

economically grow the trees on marginal land, Volk says. “Much of our region tends to have a high clay content and poor drainage,” he says, add-ing that this is land that traditional row crops would not typically grow well on.

“The fi rst step in the planting process is to control existing vege-tation—if it’s an old fi eld you need to kill it off and plow it in a fairly traditional fashion.” If that’s done in the fall, Volk recommends planting a winter cover crop to control soil erosion. “The following spring we’d plant in late April and early June, putting in just under 6,000 unrooted dormant plant cuttings per acre, which is done with a planting machine pulled by a tractor,” he says.

Page 42: Biomass Power & Thermal - January 2011

42 BIOMASS POWER & THERMAL |JANUARY 2011

Volk says his team has relied on equipment designed in Europe, where willow trees are more commonly grown as a bioenergy feedstock. “There are probably about 30,000 to 40,000 acres, largely in Sweden and the U.K. right now,” he says. The imported equipment is modifi ed to work more effectively for growing conditions in the Northeast. The problem is that shipping the machines is expensive, and getting new parts or supplies in a timely fashion can cause problems. “If something breaks and it takes a while to get here, the planting season is half gone,” Volk says. Fortunately, an upstate New York fi rm has recently obtained a license to manufacture one of the European planters for the North American market, which should help, he adds.

After the seedlings are in, the focus of the fi rst year is on weed control. “Typically after the fi rst year, the leaves drop and then we cut them down,” Volk says. “We work with willow’s ability to resprout ef-fectively. In the fi rst year you might have two to four stems per plant per year, and after coppicing it during the dormant season it’ll sprout back the next spring and you’ll get a lot more stems coming back, anywhere

from six to 15 stems per plant.” At that point, the trees look like bushes or shrubs.

Harvest should occur after three or four growing seasons. “The only thing you do during the next rotation is put a little fertilizer on in the spring as it’s sprouting, cut it again and let it grow for another three or four years,” Volk says. “If you run on a three-year cycle for example, you’ll put it in the ground once and harvest seven times.”

Currently, researchers are harvesting 4 to 5 dry tons per acre each year, but new varieties in SUNY’s breeding program are showing yield increases of 20 to 25 percent. “That’s very initial work, but I think we’ll be able to increase that steadily over time,” Volk says.

Across the U.S. in the Pacifi c West, Greenwood Resources Inc. is also selecting and breeding short-rotation woody crops, zeroing in on hybrid poplar.

Planting PoplarGreenwood manages 35,000 acres of poplar in Oregon and Wash-

ington, which are being used for biomass energy and saw and pulp logs. Jake Eaton, Greenwood’s managing director of acquisitions and resource planning, says the company believes poplar and woody crops such as eucalyptus will become the feedstock choice for biomass energy, whether for heat and power generation, gasifi cation or advanced liquid biofuels.

Greenwood’s business model is to partner with an energy or tech-nology company, identify a growing area, analyze the potential invest-ment, take the project to investors to get funding for plantation develop-ment, and then sell the feedstock to the customers.

As poplar is the most widely adapted tree species in the world, Greenwood has extended its reach into China, Europe and South America, including operations in Chile to provide feedstock to power stations, Eaton says.

Ideal locations for poplar plantations are in temperate regions of the globe. “Good conditions for poplar are deep, well-drained soils, moderate heat and sunshine, and access to water either through ground water or adequate precipitation,” he says, adding that they are grown intensively with timely weed and pest control, and fertilizer if necessary. “The production systems for biomass require 12- to 15-year rotations within which we have four to fi ve coppice cycles where the tree is har-vested,” he says.

In the Southern U.S., South Carolina-based Arborgen Inc. is de-veloping high-yielding, short-rotation crop seedlings including poplar, but its highest yielding crop is its freeze-tolerant eucalyptus, which was approved for fi eld testing by the USDA last summer.

Quantifying Eucalyptus Field testing of Arborgen’s freeze-tolerant eucalyptus has shown

the trees can survive temperatures as low as 15 degrees Fahrenheit and can therefore be planted in Florida, southern Alabama, Mississippi, Georgia, Louisiana and southern Texas.

Arborgen Product Development Manager Jeff Wright says an average 25-megawatt (MW) power plant would require about

Page 44: Biomass Power & Thermal - January 2011

44 BIOMASS POWER & THERMAL |JANUARY 2011

137,700 bone dry short tons (BDT) per year, assuming a heat rate of 11,000 Btu per kilo-watt hour, 90 percent capacity factor and a heat content of 8,000 Btu per pound. “Most woody biomass is delivered shortly follow-ing harvest, and the 25-MW power facility would require 250,400 green short tons at a moisture content of 45 percent,” he says. “To supply 100 percent of the woody bio-mass requirements in southern Georgia would require approximately 19,600 acres of plantation eucalypts on seven-year rota-tions (7 BDT per acre per year, planting and harvesting 2,800 acres annually).”

To supply all of the woody biomass requirements in south Florida would re-quire 11,500 acres of plantation eucalypts on fi ve-year rotations (yielding 12 BDT per acre per year, planting and harvesting 2,300 acres annually). “However, at present, it is unlikely that a 25-MW power facility would be supplied solely by purpose-grown trees given availability of harvest, mill and urban biomass sources not presently utilized,” Wright adds.

Challenges and the Future The system for growing willow trees at

a meaningful or commercial scale for bio-

energy needs to be further optimized, Volk says. “But it’s at a stage where it can start be-ing deployed and, as long as we learn as we go, we can improve it over time,” he says.

Brad Hunter, Greenwood business development analyst, says the company is seeing increased demand for commercial applications in Europe, and while there is interest from utilities and others in the U.S., regulatory uncertainty is weighing on the biomass market. “In the areas where these wood pellet, cellulosic ethanol and electric-ity companies are operating, there’s increas-ing demand for purpose-grown trees and management systems,” Hunter says. The demand for these trees in the U.S., however, will largely depend on permitting and engi-neering developments in bioenergy facilities, Wright says, and also continued fi nancing.

Another challenge is the upfront estab-lishment cost of tree farms. “If we’re put-ting in or near 6,000 [willow] plants per acre, we’re probably spending $800 to $1,000 an acre to get the crop established,” Volk says. “Landowners look at that and see it as a big outlay, not getting any money back for four years until the fi rst harvest.”

To help alleviate these costs, Arborgen will provide landowners an opportunity to

grow both pine biomass for bioenergy and a higher value pine for saw timber. “The anal-ysis undertaken would suggest that fi nancial returns to the landowner will be higher for the fl ex stand than either biomass or saw timber in separate plantations,” Wright says.

SUNY has done some economic model-ing of the willow production system, which, using seven three-year rotations, predicts a return of 5 to 5.5 percent. “That doesn’t sound so bad for an ag crop, but that’s over 21 years,” he says. “When you run a cash-fl ow analysis, the upfront establishment in-vestment doesn’t get paid back until about year 12 or so, about mid-way through the rotation. The last three or four harvests is when you’re making your money.”

The Biomass Crop Assistance Program should reduce establishment cost, making it much more attractive for landowners, according to Volk. When SUNY’s model is run with BCAP incentives plugged in—cost share and annual rental payments—the upfront establishment costs are recovered at fi rst harvest and cash fl ow is positive af-ter that. “The return on investment then is about 35 percent, so it makes it attractive,” Volk says. “I’m actually a little concerned that it’ll be overly attractive. In Sweden in the early ’90s, they over-incentivized willow and in a couple years they planted 20,000 or 30,000 acres but much of it was poorly es-tablished and had poor yields. There was this initial boost with the incentives, but it stalled out the program longer term.”

Hunter says Greenwood is working with several conversion facilities to apply for the BCAP. “We think it is a good opportu-nity to share the establishment risk, but we’re still waiting for more clarity from local [Farm Service Agency] staff on how it will be im-plemented,” he says.

Right now, Volk believes the cropping system is ready for deployment if a package can be put together. “That’s the way to make it work—to link those pieces together and share the risk,” he says.

GHG Emissions Trigger New AirQuality Permitting RequirementsBiomass plant operators and developers need to be aware how the U.S. EPA’s Tailoring Rule was developed and to keep track of important dates and trigger levels.BY BRIAN PATTERSON AND GEOFF SCOTT

T he U.S. EPA has recently promul-gated environmental regulations for greenhouse gas (GHG) emis-sions that will impose significant

new air quality permitting requirements on both new and existing industrial fa-cilities and projects. For new projects in particular, these requirements could substantially affect the associated cost, design, and permitting timelines.

On Dec. 7, 2009, the U.S. EPA issued

its Endangerment Finding, which deter-mined that the current and projected concentrations of the six key GHGs—carbon dioxide (CO2), methane, nitrous oxide, hydrofluorocarbons, perfluoro-carbons, and sulfur hexafluoride—in the atmosphere threaten the public health and welfare of current and future gen-erations.1 As a result of this and subse-quent rulemaking, these GHGs became “regulated pollutants” under a number

of air quality regulatory programs. Be-cause of the special nature of GHGs, including the much larger mass of emis-sions required to have an environmental impact relative to traditional air pollut-ants, the EPA has since been working to clarify how these new pollutants will be regulated under existing air quality per-mitting programs.

On June 3, the U.S. EPA published the “Prevention of Significant Deterio-

ration and Title V Greenhouse Gas Tai-loring Rule,”2 clarifying how GHGs are to be treated under these two existing air quality permitting programs (this is known as the Tailoring Rule).

As a result, existing facilities and new projects will need to consider the potential applicability of the Prevention of Significant Deterioration and Title V permitting programs (discussed further below) due to GHG emissions. In some cases, one or both of these programs may apply due solely to GHG emissions, whereas they would not have applied pri-or to issuance of the Tailoring Rule.

Of interest to the readers of Biomass Power & Thermal, as part of the Tailoring Rule, the EPA has solicited further in-formation about issues surrounding the degree of carbon neutrality that might be applied to GHG emissions resulting from the combustion of biomass fuels. Although the fact that additional infor-mation is being solicited suggests that the EPA may apply different criteria to biomass combustion GHGs in the fu-

ture, currently the Tailoring Rule does not treat these GHGs differently than the GHGs emitted from fossil fuels.

One way that GHG emissions will need to be quantified in order to assess applicability of the PSD and Title V per-mitting programs is to estimate the sum of each individual GHG annual emis-sion rate multiplied by its global warm-ing potential (GWP); this sum is known as the CO2 equivalent emission rate, or CO2e.3 For biomass combustion sources, the value for CO2e will be determined primarily by CO2 emissions. The current applicability of GHG emissions to the PSD and Title V permitting programs, based on CO2e emission levels, are de-scribed below.

Changes to Title V PermittingThe Title V permitting program pro-

vides the top tier of air quality operating permits for existing facilities and is ap-plicable only to facilities with relatively large emissions of regulated air pollut-ants. Compared to lower tier permitting,

Title V permits typically require a higher level of compliance monitoring and in-cur higher annual permitting fees. At the time of this writing, Title V permitting requirements generally apply only to fa-cilities that have the potential to emit greater than 100 tons per year (tpy) of a regulated pollutant, or 10/25 tpy of an individual/all combined hazardous air pollutants. Going forward, GHG emis-sions will trigger the need for a Title V permit as described in Table 1.

As shown in Table 1, existing facili-ties not subject to Title V permitting pri-or to July 1 will become subject to Title V permitting on that date if the facility has the potential to emit over 100,000 tons per year of CO2e and 100 tons per year of GHG on a mass basis (i.e., not accounting for GWPs). For these facili-ties, a Title V permit application must be submitted within 12 months of becom-ing subject to these requirements.

For reference, a single wood-fi red boiler with a heat input capacity of rough-ly 110 million Btu per hour (MMBtu/hr)

that has no permit restrictions on annual hours of operation would have the poten-tial to emit 100,000 tons per year CO2e.

Changes to MajorNew Source Review

The PSD new source review (NSR) permitting program provides air quality construction permits for projects at rela-tively large facilities with signifi cant in-creases of air pollutant emissions located in areas that attain national ambient air quality standards. Unlike the potential Ti-tle V permitting requirements for GHG emissions, which can apply to existing fa-cilities not making any changes, the PSD NSR permitting requirements can only be triggered by new facilities, the addition of new emission units to existing facilities, or the modifi cation of existing emission units at existing facilities (i.e., something has to change at a facility that results in a signifi cant increase in emissions).

Under the Tailoring Rule, many projects for new and modifi ed facilities that wouldn’t have previously been af-fected will be pulled into the PSD per-mitting program. Prior to the new rule, only those facilities with total emissions of greater than 250 tons per year (or 100

tons per year for certain types of facili-ties) of a regulated air pollutant could potentially be subject to PSD permitting requirements. These levels of emissions are typically indicative of a relatively large industrial facility or process. For example, a new biomass-fi red boiler emitting a reasonably low 0.20 pounds per MMBtu of nitrogen oxides (NOx) would need to have an average heat input rate of at least 285 MMBtu/hr before exceeding the 250 ton per year threshold for regulation un-der the PSD permitting program (assum-ing it was the only stationary NOx-emit-ting source at a facility with the 250 tpy threshold). With emission controls, even much larger biomass-fi red industrial boil-ers could avoid the PSD program.

Under the new GHG regulations, relatively small facilities with combustion sources will be subject to PSD review for GHGs and, likely, for other pollutants as well. The new GHG PSD applicability thresholds will phase in as shown in Table 2.

These GHG emission thresholds ap-ply to all new and modifi ed sources com-bined at a facility. In addition, starting July 1, if a facility (new or existing) has to-tal GHG emissions exceeding 100,000 tpy

CO2e, and new emissions (due to adding new sources or modifying existing sourc-es) of other pollutants exceeding their associated Signifi cant Emission Rates (SERs), the project will be subject to PSD NSR requirements for those pollutants as well, even if facility-wide emissions of no other pollutants exceed 100/250 tpy (SERs for many regulated pollutants fall in the range of 10 to 40 tpy). As an exam-ple, a new biomass power plant consisting of a 150 MMBtu/hr wood-fi red boiler, steam turbine, and ancillary fuel handling equipment could have the following max-imum potential annual emissions:

• 25 tpy of particulate matter less than 10 microns (PM10) (SER of 15 tpy)

• 130 tpy of NOx (SER of 40 tpy)• 136,000 tpy of CO2e (SER of

75,000 tpy)Prior to July 1, this project would

not be subject to PSD NSR permitting requirements because emissions of each non-GHG pollutant are less than 250 tpy. Starting July 1, such a project would be subject to PSD NSR requirements for PM10, NOx, and GHGs because CO2e emissions exceed 100,000 tpy and maxi-mum potential emissions of all three pol-lutants exceed their associated SER, likely

increasing the cost of the project sig-nifi cantly.

The PSD NSR permitting program includes potential requirements such as:

• Use of Best Available Control Technology for control of air pollutant emissions.

• Dispersion modeling to dem-onstrate compliance with ambient air quality standards and PSD increments.

• Dispersion modeling to demon-strate potential impacts to visibility and deposition within Class I protected ar-eas.

• Pre- or post-construction moni-toring of ambient air pollutants.

Compliance with these additional requirements under the PSD NSR pro-gram can range from tens of thousands to millions of dollars, depending on the project.

In November 2010, the EPA re-leased a guidance document for imple-mentation of the new GHG regulations. Among other topics, this document discusses potential approaches to eval-uating BACT for GHGs. Briefl y, some of the guidance provided is as follows:

• BACT for new facilities will need to evaluate energy effi ciency measures for the emission unit itself as well as overall energy effi ciency of all aspects of the facility pertaining to the energy produced by the facility and used at the facility site (e.g., steam and/or electricity).

• BACT for modifi ed existing fa-cilities only need to evaluate energy ef-

HURST BOILER& WELDING CO., INC

fi ciency measures for the new or modifi ed emission units themselves.

• Energy effi ciency improvements to be evaluated include changes to the emis-sion unit design, but not wholesale chang-es to the fundamental business purpose for the proposed emission unit or facil-ity. For example, a proposed wood-fi red boiler need not consider replacement with

a natural gas boiler. However, the guid-ance document gives the specifi c example of a subcritical steam pressure boiler that would need to evaluate the improved en-ergy effi ciency provided by a supercritical steam pressure boiler, which is likely to be a cost-effective change relative to associ-ated reductions in GHG emissions.

• Capture and use (or sequestration)

In this new era of federal regulation of GHGs, the Tailoring Rule provides what is likely to be only the first step in a program of air quality permitting requirements aimed at reducing overall GHG emissions from industrial sources.

¦EMISSIONS

biomass facilities might get pulled into the PSD NSR permitting program.

In addition to evaluating the po-tential applicability of these permitting programs under the new rules, facil-ity operators and developers should track future GHG rulemaking resulting from:

• The EPA’s future determina-tions concerning the degree of carbon neutrality associated with combusting biomass-derived fuels. This could alter the applicability of the permitting pro-grams discussed in this article to emis-sion units combusting biomass-derived fuels and/or specifi c source categories.

• The EPA’s indication in the Tai-loring Rule that they intend to eventu-ally lower the GHG emissions thresh-olds for applicability of the permitting programs discussed in this article, pulling in even smaller facilities. These changes will be fi nalized no later than July 1, 2012, with implementation fol-lowing one year later. However, the EPA committed in the Tailoring Rule that no facilities with GHG emissions (or emission increases) below 50,000 tpy CO2e would be pulled into these programs before April 30, 2016.

In this new era of federal regula-tion of GHGs, the Tailoring Rule pro-vides what is likely to be only the fi rst step in a program of air quality permit-ting requirements aimed at reducing overall GHG emissions from industrial sources.

of GHGs should at least be considered and evaluated within the framework of the BACT determination process.

In general, if PSD NSR requirements for GHGs are triggered, all BACT op-tions that would reduce GHG emissions to the atmosphere must be considered as part of the evaluation process and either dismissed on the basis of technical infea-sibility, dismissed on the basis of adverse environmental impact, dismissed on the
