美國能源部（DOE）編制了本環(huán)境評估報(bào)告（EA），以評估向Viresco Energy，LLC（Viresco）提供財(cái)政援助以建設(shè)和運(yùn)營位于猶他州卡納布的煤炭和生物質(zhì)燃料試點(diǎn)工廠的潛在影響。該工廠將位于猶他州學(xué)校和機(jī)構(gòu)信托土地管理局租賃給Viresco的土地上。該試點(diǎn)工廠占地約1.5英畝，占地10英畝，位于卡納布猶他市區(qū)南部約2.5英里處。2010財(cái)政年度能源和水資源開發(fā)及相關(guān)機(jī)構(gòu)撥款法案（公法111-85）包括當(dāng)時(shí)猶他州參議員貝內(nèi)特為“猶他州煤和生物質(zhì)燃料試驗(yàn)工廠”贊助的250萬美元專項(xiàng)撥款。根據(jù)該專項(xiàng)撥款，能源部將向Viresco提供財(cái)政援助，以支持其設(shè)計(jì)，中試規(guī)模蒸汽加氫氣化設(shè)施的建造和測試。根據(jù)一項(xiàng)多邊協(xié)議，能源部將提供2404000美元（約占研究開發(fā)項(xiàng)目總成本的80%），Viresco將貢獻(xiàn)剩余的601000美元。試點(diǎn)工廠將由Viresco建造、擁有和運(yùn)營。Viresco負(fù)責(zé)獲得項(xiàng)目所需的許可證和其他授權(quán)；DOE對項(xiàng)目或其運(yùn)營沒有監(jiān)管權(quán)。根據(jù)合作協(xié)議，Viresco將運(yùn)營該試驗(yàn)工廠，并在數(shù)月內(nèi)收集一系列總計(jì)30天的試運(yùn)行數(shù)據(jù)；在能源部的財(cái)政援助結(jié)束后，Viresco計(jì)劃為繼續(xù)運(yùn)營尋求額外資金。Viresco提出的項(xiàng)目的目標(biāo)是對蒸汽加氫氣化反應(yīng)（SHR）過程進(jìn)行中試評估。試驗(yàn)工廠將是一個(gè)小型設(shè)施，旨在評估利用蒸汽加氫氣化將煤和生物質(zhì)（如農(nóng)業(yè)或木材加工廢料）轉(zhuǎn)化為合成氣（合成氣）并最終轉(zhuǎn)化為清潔燃料（如替代天然氣、無硫費(fèi)托柴油、噴氣燃料）的技術(shù)可行性，二甲醚和甲烷。該SHR氣化技術(shù)的中試成功運(yùn)行，將為開發(fā)該工藝的商業(yè)化途徑提供所需的工程信息。該項(xiàng)目支持能源部以高效和環(huán)境可接受的方式開發(fā)和利用國內(nèi)煤炭和可再生資源的目標(biāo)。這項(xiàng)技術(shù)采用先進(jìn)的氣化工藝，生產(chǎn)清潔燃料。向煤炭原料中添加生物質(zhì)還可減少溫室氣體凈排放量。環(huán)境評估發(fā)現(xiàn)，Viresco擬議項(xiàng)目最顯著的潛在變化將出現(xiàn)在以下領(lǐng)域：土地利用、美學(xué)、空氣質(zhì)量、固體和危險(xiǎn)廢物、公用事業(yè)和社會(huì)經(jīng)濟(jì)。在分析這些潛在變化時(shí)，沒有發(fā)現(xiàn)明顯的環(huán)境影響。
The U.S. Department of Energy (DOE) prepared this Environmental Assessment (EA) to evaluate the potential impacts of providing financial assistance to Viresco Energy, LLC, (Viresco) for its construction and operation of a Coal and Biomass Fueled Pilot Plant, that would be located in Kanab, Utah. The plant would be located on land leased to Viresco by the Utah School and Institutional Trust Lands Administration. The Pilot Plant would occupy approximately 1.5 acres of a 10-acre site located approximately 2.5 miles south of the downtown area of Kanab, Utah. The Fiscal Year 2010 Appropriations Act for Energy & Water Development and Related Agencies (Public Law 111-85) included a $2,500,000 earmark sponsored by then Senator Bennett of Utah for the “Utah Coal and Biomass Fueled Pilot Plant.” In accordance with the earmark, DOE would provide financial assistance to Viresco to support its design, construction, and testing of a pilot-scale steam hydrogasification facility. Under a costsharing agreement, DOE would provide $2,404,000 (approximately 80 percent of the total cost of the research and development project) and Viresco would contribute the remaining $601,000. The Pilot Plant would be constructed, owned, and operated by Viresco. Viresco is responsible for obtaining the permits and other authorizations needed for the project; DOE would have no regulatory authority over the project or its operation. Under the cooperative agreement, Viresco would operate the Pilot Plant and collect data for a series of test runs totaling 30 days of operation over a period of months; after DOE’s financial assistance ends, Viresco plans to seek additional funding for continued operations. The objective of Viresco’s proposed project is to conduct a pilot-scale evaluation of the Steam Hydrogasification Reaction (SHR) process. The Pilot Plant would be a small-scale facility designed to evaluate the technical feasibility of using steam hydrogasification to convert coal and biomass (such as agricultural or wood processing waste) into synthesis gas (syngas), and ultimately into clean fuels such as substitute natural gas, sulfur-free Fischer-Tropsch diesel, jet fuel, dimethyl ether, and methane. The successful operation of this SHR gasification technology at a pilot scale would provide engineering information needed to develop a commercialization pathway for this process. This project supports DOE’s goal of developing and using domestic coal and renewable resources in an efficient and environmentally acceptable manner. This technology uses an advanced gasification process and produces clean fuels. The addition of biomass to the coal feedstock also reduces net greenhouse gas (GHG) emissions. The EA found that the most notable potential changes from Viresco’s proposed project would occur in the following areas: land use, aesthetics, air quality, solid and hazardous wastes, utilities, and socioeconomics. No significant environmental effects were identified in analyzing these potential changes.
