環(huán)境影響報(bào)告書草案評(píng)估了美國(guó)能源部提議的一項(xiàng)行動(dòng)可能產(chǎn)生的環(huán)境影響，該行動(dòng)旨在為密西西比州肯珀縣的先進(jìn)發(fā)電廠的建設(shè)和運(yùn)營(yíng)提供成本分?jǐn)傎Y金，并可能提供貸款擔(dān)保。該項(xiàng)目是在美國(guó)能源部的清潔煤炭電力倡議下選定的，以演示IGCC技術(shù)。密西西比電力公司也被邀請(qǐng)根據(jù)2005年的能源政策法案提交一份正式的貸款擔(dān)保申請(qǐng)。發(fā)電組件(即在美國(guó)，煤炭氣化爐、合成氣(syngas)清潔系統(tǒng)、聯(lián)合循環(huán)裝置和配套基礎(chǔ)設(shè)施將把煤炭轉(zhuǎn)化成合成氣來(lái)驅(qū)動(dòng)燃?xì)廨啓C(jī)，而燃?xì)廨啓C(jī)排出的熱廢氣將從水中產(chǎn)生蒸汽來(lái)驅(qū)動(dòng)汽輪機(jī)。這三個(gè)渦輪機(jī)合在一起將產(chǎn)生582兆瓦的電力。盡管能源部的資金只會(huì)支持IGCC電廠，但該項(xiàng)目將包括新建輸電線路和升級(jí)一些現(xiàn)有的輸電線路、一個(gè)地表褐煤礦、一條天然氣供應(yīng)管道、一條再生水供應(yīng)管道和一條二氧化碳管道。這些設(shè)施的建造和操作在本“環(huán)境影響報(bào)告書”草案中被視為相互關(guān)聯(lián)的行動(dòng)。
This Draft EIS assesses the potential environmental impacts that would result from a proposed DOE action to provide cost-shared funding and possibly a loan guarantee for construction and operation of advanced power generation plant in Kemper County, Mississippi. The project was selected under DOE’s Clean Coal Power Initiative to demonstrate IGCC technology. Mississippi Power also was invited to submit a formal application for a loan guarantee under the Energy Policy Act of 2005. The power generation components (i.e., coal gasifiers, synthesis gas [syngas] cleanup systems, combined-cycle unit, and supporting infrastructure) would convert coal into syngas to drive gas combustion turbines, and hot exhaust gas from the gas turbines would generate steam from water to drive a steam turbine. Combined, the three turbines would generate a nominal 582 megawatts (MW) of electricity. Although DOE funding would support only the IGCC power plant, the project would include new electrical power transmission lines and upgrades of some existing transmission lines, a surface lignite mine, a natural gas supply pipeline, a reclaimed water supply pipeline, and a carbon dioxide pipeline. The construction and operation of these facilities are considered connected actions in this Draft EIS.
