Associated actions include the planned subsidence of much of the mined area, the construction of five Bleeder Shaft Facilities, and the processing of the coal at an existing Coal Preparation Plant. Type of document: Final Environmental Impact Statement Lead agency: Tennessee Valley Authority Cooperating agency: U.S. Environmental Protection Agency To request information, contact: Elizabeth Smith Tennessee Valley Authority 400 West Summit Hill Drive, WT11B Knoxville, Tennessee 37902-1499 E-Mail: [email protected] Abstract: TVA evaluates a No Action and Action Alternative in this EIS. The Action Alternative consists of TVA approving the extraction of TVA-owned coal from an area of approximately 12,125 acres, the construction and operation of five Bleeder Shaft Facilities, and the planned subsidence of the ground surface above the extracted coal. Connected actions include processing, storing, and transporting the extracted coal via existing and proposed facilities. Under the No Action Alternative, TVA would not approve the extraction of the TVA-owned coal, and extracting, processing, storing, and transporting other coal in the area would continue. The Action Alternative is preferred due to being economically feasible, having similar environmental impacts to other alternatives, and meeting the purpose and need. Final Environmental Impact Statement i This page intentionally left blank Summary EXECUTIVE SUMMARY Purpose and Need for Action TVA owns the coal reserves beneath the Project Area and executed a coal lease agreement in July 2002 with Sugar Camp Energy, LLC (Sugar Camp) to mine TVA-owned coal in Franklin, Hamilton, and Jefferson counties, Illinois. The purpose of the coal lease agreement is to facilitate the recovery of TVA-owned coal reserves in an environmentally sound manner. The Proposed Action would implement the terms of the existing coal lease agreement and recoup TVA’s investment. Under the terms of the coal lease agreement, Sugar Camp may not commence mining of TVA-owned coal reserves until completion of all environmental reviews required for compliance with applicable laws and regulations. In fulfillment of its responsibilities under the National Environmental Policy Act (NEPA), TVA has prepared this Final Environmental Impact Statement to consider whether TVA will approve the proposed plan to extract TVA-owned coal within a 12,125-acre shadow area permitted under Significant Boundary Revision (SBR) Number (No.) 6 of Illinois Underground Coal Mine (UCM) Permit No. 382 and process the TVA-owned coal at existing and proposed facilities within the surface effects area of Sugar Camp Mine No. 1. Alternatives In this environmental impact statement (EIS), TVA evaluates a No Action Alternative and Action Alternative. The Action Alternative would consist of TVA approving the plan to extract TVA- owned coal reserves within a 12,125-acre portion of the overall SBR No. 6 shadow area (hereafter, the Shadow Area). The Action Alternative would involve the associated construction and operation of five Bleeder Shaft Facilities in different locations within the Shadow Area, together totaling approximately 27 acres. Planned subsidence (controlled sinking of the ground at the surface) of approximately 10,549 acres within the Shadow Area would result. Connected actions include processing of the extracted TVA-owned coal at an existing Coal Preparation Plant within an existing 2,420-acre surface effects area; treatment of the byproducts at both existing facilities and one new facility, known as the East Refuse Disposal Area; surface storage of coal; and offsite transport of processed coal via an existing rail loop. These facilities also process, store, and transport privately owned coal mined without TVA approval. Together, the 12,125-acre Shadow Area and the 2,420-acre surface effects area compose the Project Area. TVA’s analysis of the Action Alternative takes into account the proposed mining plan in addition to the effects associated with ongoing mining operations. Under the No Action Alternative, TVA assumes that Sugar Camp would continue the previously approved mining of approximately 25,847 acres of TVA-owned coal and privately owned coal (hereafter, the private/TVA-approved shadow area). In addition, Sugar Camp would continue processing, storing, and transporting the previously approved TVA-owned and privately owned coal. Affected Environment The Sugar Camp Mine No. 1 is located in Hamilton and Franklin counties in Illinois. The regional character is mostly rural, with agricultural and pasture fields, flat terrain with rolling hills, forested areas, and generally small towns and communities. The Project Area is located east of the City of Benton. Current land use within much of the surface effects area is heavy industrial and includes operation of existing facilities for the processing, storage and transport of coal. Within the Shadow Area, current land use is primarily rural agricultural with some scattered residences. Nine historical archaeological sites, one Final Environmental Impact Statement iii Sugar Camp Energy, LLC Mine Number 1 – Boundary Revision 6 Precontact period archaeological site, and three potentially historic buildings have been recorded within the Project Area or vicinity. The other buildings in the vicinity of the Project are residential and/or farmstead buildings. Five churches and three cemeteries of unknown age are present within the Shadow Area. The Shadow Area is located in the southern portion of the Illinois Basin coalfield. The Herrin No. 6 coal seam, which is proposed to be mined, lies from 650 feet to more than 900 feet below ground. Seven named streams, Granny Creek, Carlton Branch, Web Hill Branch, Sugar Camp Creek, Campbell Branch, Sullivan Branch, Ewing Creek, and Middle Fork Big Muddy River as well as multiple unnamed tributaries and creeks flow through the Shadow Area and surface effects area. The majority of the Project Area is characterized by a heavily fragmented landscape dominated by early successional habitat, such as pastures and hayfields. Forested areas and wetlands are scattered throughout and support a variety of plants and animals. Environmental Consequences Coal mining activities would occur under either the No Action Alternative or the Action Alternative. Reasonably foreseeable greenhouse gas emissions, including downstream emissions, are quantified. Other environmental consequences associated with either alternative, including the Action Alternative, have been deemed not significant and, for the most part, would be temporary due to minimization and mitigation efforts required in Illinois Department of Natural Resources (IDNR) permit conditions. Minor, temporary impacts to soils, groundwater, floodplains, surface waters and wetlands, vegetation, wildlife, and aquatic life would occur with either alternative. Other resources that would be temporarily affected under either alternative include prime farmland, water quality and supply, natural areas, land use, transportation, utilities, noise, and visual. These impacts would be minimized or mitigated per IDNR permit requirements. Under either alternative, permanent changes to geology would occur due to the removal of a portion of the Herrin No. 6 coal seam. Construction of the East Refuse Disposal Area, which constitutes an expansion of the existing surface effects area under either alternative, would result in permanent impacts to utilities, North Bobtail Road, wetlands, and land use. These impacts would be offset through required minimization and mitigation efforts. Solid and hazardous waste and human health and safety impacts would be avoided due to compliance with relevant regulations and avoidance and mitigation measures under either alternative. Relative beneficial effects on socioeconomics would occur with either alternative. Environmental justice impacts would be avoided due to compliance with IDNR permit requirements to avoid, minimize, or mitigate the adverse effects of mining operations. Under the Action Alternative, TVA would require appropriate consultations with the pertinent federal and state agencies to ensure impacts associated with the Bleeder Shaft Facilities to cultural resources and to federally and state-listed species are avoided, minimized, or mitigated. Generally, these consultations are also required under the No Action Alternative, per IDNR permit conditions. iv Final Environmental Impact Statement Contents Table of Contents CHAPTER 1 – PURPOSE AND NEED FOR ACTION ...................................................................... 1-1 1.1.

  • A Floristic Study of a Southern Illinois Swampy Area
    No. 2 NEW SPECIES OF CTENICERA 89 A FLORISTIC STUDY OF A SOUTHERN ILLINOIS SWAMPY AREA ROBERT H. MOHLENBROCK Department of Botany, Southern Illinois University, Carbondale, Illinois In the western part of Union County in southwestern Illinois is a unique area of swamps and woodlands of low ground. This paper is an endeavor to discuss floristic relationships of the species of vascular plants which occur in this area. These swamps of Union County occur in the following sections of T 11 S, R 3 W: 9, 16, 17, 21, 28, and 33. * A small portion of T 12 S, R 3 W, sections 3 and 4 is also included (fig. 1). Within this area, numerous habitat types are found. This study deals only with the floristics of the swamp-inhabiting plants. A high range of hills forms the eastern border of the swamp. At the western limits of these hills, massive limestone bluffs which once bordered the Mississippi River are exposed. These often nearly vertical bluffs are in places almost 350 feet high. They are dissected by numerous east-west ravines which are covered with dense vegetation. Hill prairies are located along the western-facing edges of many of these bluffs. These treeless areas are minute replicas of prairies to the west. The swamp vegetation is found in an area from one-eighth of a mile to nearly a mile wide and for a length of about six miles. The southern end of the area is occupied by a finger-shaped lake known as Wolf Lake. The lake extends for nearly two miles, becoming shallower at its northern end where it gives rise to a deep swamp.

  • Chapter 3: Affected Environment
    Chapter 3:Affected Environment Chapter 3: Affected Environment 3.1 Introduction Chapter 3 provides an overview of Crab Orchard National Wildlife Refuge and the resources it pro- vides in terms of habitat, wildlife and people. 3.2 Physical Environment 3.2.1 Physiography The physiography of the northern and southern portions of the Refuge is quite different. The terrain of the northern portion of the Refuge is character- ized by low relief, broad valleys, and relatively well- developed drainage systems while the southern por- tion of the Refuge is uplands with narrow ridges dis- sected by deep, narrow valleys with steep slopes and numerous sandstone outcrops. The northern portion of the Refuge is covered with a heterogeneous mixture of rock fragments ranging in size from clay to boulders deposited by glaciers on bedrock. Generally the slopes in the area are less than 3 percent. The southern portion of the Refuge is part of a continuous ridge extending from Prairie restoration, Crab Orchard NWR Battery Rock on the Ohio River to Horseshoe Bluff overlooking the Mississippi River. The hills are highly dissected uplands with little flat land and 3.2.2 Geology nearly all of the area has steep slopes, most in The bedrock underlying the Refuge is of Pennsyl- excess of 10 percent slope. vanian age. In the northern part of the Refuge, the The Refuge's elevation ranges from less than 380 bedrock is covered by a thin layer of glacial till of feet above mean sea level at Crab Orchard Creek in Illinoian age. During the Wisconsin glacial age, the Jackson County to over 740 feet at the southeast weathered Illinoian glacial till was covered by the corner of the Refuge in Union County.

  • Illinois Prairies 101
    Illinois Department of Natural Resources Division of Education One Natural Resources Way Springfield, IL 62702 ENTICE – Environment and Nature Training Institute for Conservation Education Illinois Prairies 101 Part I Geology Many factors interact to determine the vegetation of any site, regardless of size. Bedrock geology, glacial history, soils, moisture, climate, grazing animals, and fire have combined to directly influence the distribution of prairies and forests within Illinois. With a different climate, glacial history or fire history, the vegetation of Illinois would have been vastly different from that observed and described by the French explorers when they arrived in the late 1600s. Some of these factors, such as bedrock, are largely obscured in Illinois by a thick layer of till deposited by the action of glaciers many thousands of years ago. The only places where bedrock is exposed are along the deeply incised valleys of the Illinois, Mississippi, Ohio and Wabash rivers and their tributaries, or along fault lines at various locations throughout the state. The bedrock of Illinois resulted from the deposition of marine organisms during the Paleozoic and Mesozoic eras in the period 65 to 570 million years ago. Bedrock from these two geologic time periods differs not just in age, but also in location and thickness. Paleozoic bedrock, the most widely distributed, is present throughout much of Illinois. Its maximum thickness is approximately 14,000 feet compared to the maximum thickness of only 500 feet for Mesozoic era bedrock present in southern Illinois. The most common and probably best-known type of bedrock in Illinois is limestone, a sedimentary rock formed at the bottom of ancient seas mostly by the deposition of shells, coral skeletons, and secretions from certain types of algae.

  • Longwall MINING UNDER a PUBLIC LAKE and WILDLIFE REFUGE: PLANNING for SUBSIDENCE IMPACTS
    LoNGWALL MINING UNDER A PUBLIC LAKE AND WILDLIFE REFUGE: PLANNING FOR SUBSIDENCE IMPACTS by Daniel Barkley' Abstract: Rend Lake is a man-made water body in south central Illinois completed by the Corps of Engineers in 1972. Approximately 18,900 acres of water and 20,000 acres of managed land encompass the project. The lake serves as a significant public water supply for the region and also provides outdoor recreation opportunities such as camping, swimming, boating, fishing and hunting. Over the past two decades, several coal companies have conducted both high extraction retreat and longwall mining operations under and adjacent to Rend Lake. The resulting surface subsidence has altered shoreline locations and increased water depths. Mitigation of subsidence impacts has been achieved by a combination ofland acquisition to expand the project as well as site specific mitigation techniques to restore existing capabilities and uses. The last surviving company is currently conducting longwall operations under a State of Illinois managed wildlife refuge located on the Nason Point Peninsula. The longwall operations will inundate a portion of the peninsula's land surface and could potentially impact the existing habitats of the refuge. Issues at stake are potential impacts to shore birds and the migratory Canada goose. Several state and federal agencies have come together to work with the coal company to develop an acceptable mitigation plan. This paper provides an overview of the permitting process, public concerns raised and the efforts to arrive at an acceptable mitigation plan. Modeled changes in topography and potential impacts on the management of the refuge are examined.

  • Big & Little Muddy Rivers Report
    AERIAL ASSESSMENT REPORT FOR Big and Little Muddy Rivers Jackson County November 2005 Prepared by Wayne Kinney for IL. Department of Agriculture 1 The Big Muddy River watershed TMDL final report list only segment N12 (Fig. 1) as impaired. This eight mile reach is impacted by manganese, sulfates, pH and DO. The TMDL report has determined the manganese and sulfates are potentially from groundwater contamination caused by abandoned coal mines and the likely source of the DO impairments in this reach is a lack of aeration caused by stagnant stream conditions and elevated in stream temperatures. N 12 Fig. 1 Map of Aerial Assessment of Big and Little Muddy Rivers and TMDL Segment Assessment Procedure Low level geo-referenced video was taken of the Big and Little Muddy Rivers in March, 2004. Video taping was completed by Fostaire Helicopters, Sauget, IL, using a camera mounted beneath a helicopter to record data from just above tree top level in DVD format for further evaluation and assessment. Video mapping began near Sand Ridge where the Big Muddy enters the Mississippi River Bottoms approx. 4 miles southwest of Murphysboro, IL. The mapping progressed upstream to the confluence with the Little Muddy River east of De Soto, IL and then followed the Little Muddy River to a point 2 approximately 1 mile above the Jackson County line southeast of DuQuoin, IL. Aerial video of tributaries was not part of the project, regardless of the stream size or vegetation. After videotaping the stream, the DVD tapes were processed by USGS to produce a geo- referenced DVD showing flight data and location.
