FOREWORD

Penn Virginia Land Company submitted this site for evaluation for potential

development as an alternative energy facility. The site was evaluated against

preliminary criteria which identifies characteristics beneficial for development of a wind,

solar, biomass, nuclear, or coal-to liquid (CTL)/coal-to-gas (CTG) facility. This site

benefits from a location in the Western Kentucky Coal Fields, access to substantial

water resources and flexible transportation options.

The Penn Virginia Land Company has offered the Area A property to be evaluated as a

potential energy facility. The development of an energy facility, whether for CTL/CTG,

wind, nuclear, solar or biomass, must consider basic common factors which include

assets like access to transportation, general topography, proximity to public access

areas, and available utilities.

GENERAL SITE CONSIDERATIONS

Ownership

The surface and coal under the property are owned by Penn Virginia. Oil wells located

on the site are managed by Continental Resources.

Penn Virginia -Area A – Henderson County Page 1

Size

Penn Virginia offers approximately 1,000 acres of previously mined land in Henderson

County on the Green River, immediately south of the Audubon Parkway (USGS

Spottsville, Reed, Curdsville and Delaware topographic quadrangles). The site is

adjacent to additional property to the northeast available for development, equaling over

2,600 acres. Property to the southwest is currently under development as a coal

gasification facility.

Topography

The proposed site was previously surface mined. The limited residential land use in the

area is not adjacent to the site, and it is not anticipated that other land uses nearby will

pose issues with development of an energy facility as a result of the previous land use.

Significant portions of the property have been surface mined and may have up to 100

feet of mine spoil placed above the residual material. This may present a challenge in

siting those aspects of an alternative energy facility that require substantial foundations.

Floodplain and Wetlands

Some areas of the site located along the Green River and along the west side of the

property were noted to lie within the 100-year floodplain, but the vast majority of the

proposed site is not impacted by floodplains. A small area of wetlands is identified,

associated with the mouth of the stream located on the western edge of the property.

The size and location of the identified wetland should not impede the development of

the site.

Site Hazards

Environmental databases were reviewed to determine if there is regulatory evidence

that the site or a nearby property has been impacted by environmental issues.

According to a 2008 FirstSearch Environmental Database Report, the Penn Virginia

Area A site was not identified on any environmental databases searched nor were any

other facilities identified with the radius search.


Oil and Gas Wells

There are producing oil wells located on the site which are managed by Continental

Resources. These wells are located primarily along ridges above the main

development area and are not expected to pose significant issue for the proposed

development.

Producing oil well

Sensitive Areas

The proximity of non-attainment areas and Class I Visibility Areas to the site was

examined for potential impacts to air quality or limitations on a required air permit for a

CTL/CTG or biomass facility. The nearest air quality non-attainment area is located at

least 20 miles distant in Evansville, Indiana. Careful planning may be required,

however, to assure that development or operation does not adversely impact Mammoth

Cave National Park, a Class I Visibility Area located approximately 75 miles southeast

of the proposed site.


Stream located on proposed site

State water data was searched to determine if designated impaired streams in the area

might affect discharge requirements for an energy facility. The site is not located near

impaired bodies of water which could complicate planning or development by limiting

flexibility with regard to discharge requirements. The proposed site is located along the

Green River (part of Green and Tradewater River Basin). There are no public water

intakes within 25 miles downstream of the site. Use designations for the Green River in

accordance with 401 KAR 10:026 include warm water aquatic habitat, primary contact

recreation, secondary contact recreation, and drinking water source. The Green River

at this location is not on the 303(d) List of Surface Waters for impaired uses.

The site lies within four USGS topographic map quadrangles. The northeastern map,

Reed, documents the potential presence of the Indiana bat as a federally listed

endangered species within the area covered by the map. State threatened or

endangered species identified in the same area include the American Coot, listed as

endangered, and the Indiana bat and the Bald Eagle as state threatened species. The


Northern Harrier is a state listed threatened species which has been reported to be

potentially present within the area covered by the Spottsville map and the Hooded

Merganser (water fowl) is listed as a state threatened species within the Delaware map

area. Additional investigation to assure that alternative energy facility development will

not significantly degrade the habitat of these species may be required associated with

planning activities. However, due to previous mining at the site it is not anticipated that

the proposed development will significantly impact critical habitats.

There are no sites listed on the National Register of Historic Places within 100 meters of

the project area. Nineteen surveyed properties (identified as potential historical/ cultural

resources based on established criteria, but for which no official classification has been

completed) were identified near the proposed site, but are found on the opposite side of

the Green River in Ohio County, suggesting minimal to no impact from development at

the proposed site. Thirteen previously recorded archaeological sites were identified in

the project area, two of which were described as potentially eligible for listing as cultural

resources. A cemetery was identified nearby. If it would be disturbed during

development of the site, it would require prior investigation and planning. Further

investigation is recommended prior to development to ensure that archaeological

resources and the neighboring cemetery are not impacted.

Geological Assets

Siting considerations for a biomass or CTL/CTG process must take into account

available geological assets for potential sequestration. Analysis by the Kentucky

Geologic Survey (KGS) ranked the geologic assets for the site as fair. The following

graphic was prepared by the KGS and depicts certain assets of the proposed site. The

graphic depicts substantial oil production areas, miscible (2,500+ feet deep) and

immiscible (less than 2,500 feet deep) wells surrounding the site, many of which have

been further developed with water flooding. A large area of faulting is located south of

the site. The site is labeled 2.14 on the graphic map.


The primary sequestration target formations for a biomass or CTL/CTG facility in this

locale (Ordovician Knox with the primary seal being the overlying Black River

carbonates and Maquoketa shales) are reported by the KGS to lie immediately beneath

the proposed development site. Deep, un-mineable coal beds are not identified in the


immediate area. The Knox Formation is found an average of 6,900 feet deep at this

location. These assets are somewhat offset by merely adequate seismic stability. The

proximity of faults to a site may impact the development of a nuclear, biomass, or

CTL/CTG facility. A biomass or CTL/CTG facility constructed at the proposed site could

experience amplified ground motion effects if constructed on unconsolidated alluvial

material.

Utilities

Basic electric service is presently available on site, with gas and water service available

in the vicinity. Sewer service is not available in the area necessitating planning for on-

site treatment facilities as part of the development process. It is expected that

broadband Internet access, which is available in the area, will become available to the

site with the development of the adjoining gasification facility.

Transportation

Road access is essential for any large industrial facility and particularly so for an energy

facility that brings in its fuel or trucks out its product. Road access to the site is

adequate for coal and worker transport. This site is accessed by the Audubon Parkway,

a four-lane highway which is listed as a state maintained coal haul route in Henderson

County for approximately 15 miles. Unpaved haul roads are also located throughout

the site and are isolated from public access.

Existing barge facility adjacent to the property

Although not a significant siting consideration for a solar, nuclear or wind facility, a

biomass or CTL/CTG facility will require several transportation options due to the

substantial feedstock required for these technologies. In addition to access via truck

transport, Patriot Coal operates a barge facility adjacent to the proposed site which may

be available to enhance feed stock supply and could be expanded to provide transport

for products. Rail transport is not available at the proposed site.

Transmission Any energy facility will require access to electric transmission points. A 69kV line

should be an adequate capacity to carry generated power from a solar facility in

Kentucky. A nuclear, biomass, wind or CTL/CTG facility would require access to larger

electric transmission points. The nearest existing electricity grid access is located at two

substations located on the Patriot Coal property at the western edge of the site, both

serviced by 69kV lines. The nearest high capacity electric transmission line is located

less than ten miles from the proposed site. Though this line is not immediately present

at the subject site, it is estimated that connection could be made using existing right-of-

way. In addition, development of the adjacent gasification facility will result in high

capacity electric transmission facilities which may be accessible to the proposed site.


69kV transmission lines and substation

Natural gas is used as a feedstock and fuel in CTL/CTG and for some biomass facilities,

making access to a supply important. Additionally, if the facility makes synthetic natural

gas, access to a transmission pipeline will be important in getting products to market.

High capacity natural gas transmission is available at the far side of the adjacent

property to the southwest.

Water Supply


Available water supply is a critical project component for the development of a

CTL/CTG, biomass or nuclear facility. The proposed property is adjacent to the Green

River which offers a mean annual flow at this location of 6,843 million gallons per day

(MGD) or 9.9 trillion gallons per minute (gpm). The low-flow 7Q2 and 7Q10 are 273 and

105 MGD, respectively. The low-flow 7Q10 is the lowest mean flow during seven

consecutive days over a ten-year period. The low-flow 7Q2 is the lowest mean flow

during seven consecutive days over a two year period. If the 7Q10 is less than 3.8

MGD, the amount of water required for a 10,000 barrel per day facility, the stream would

not be recommended as a sole source for dependable year-round water removal. The

nearest USGS monitoring station is located at Calhoun, KY and has recorded the lowest

Page 10

mean annual flow as 3,453 MGD or 5 trillion gpm. Based on this data the Green River

should provide adequate raw water supply for a CTL/CTG facility, which will need in

excess of 2,500 gpm or for a biomass facility that may have cooling water needs. The

Green River may also provide the minimum adequate raw water supply for a nuclear

facility, which would need in excess of 8,000 gpm or 11.5 MGD for cooling purposes.

Workforce Availability

Development of a CTL/CTG, biomass, or nuclear facility would require access to an

adequate supply of construction and skilled labor. The labor market area for the

proposed site would include Henderson, Daviess, McLean, Hopkins, Webster and

Union counties in Kentucky, Gallatin County in Illinois and Gibson, Vanderburgh and

Warrick counties in Indiana. Based on information developed by the Kentucky

Economic Development Cabinet in October 2008, these nine counties have a civilian

workforce of over 250,000. Henderson County labor market

Other General Characteristics The proximity to military sites was reviewed in order to consider the potential impact of

an energy facility to military training routes or long range radar. Based upon information

produced by the Federal Aviation Administration’s Department of Defense Screening

Tool, the proposed site is greater than 5 miles from any military site or long range radar.

Atmospheric extremes, such as tornadoes, are capable of structurally damaging a

facility and must be considered particularly during siting for a solar, nuclear, or wind

facility. Based upon Federal Emergency Management Agency mapping, the site is at a

moderate to high risk for tornado activity.

TECHNOLOGY SPECIFIC CONSIDERATIONS CTL/CTG

In addition to the common factors described above for energy site development, unique

factors specific to a particular technology must be considered. For a CTL/CTG facility,

access to coal resources is important. Penn Virginia A site offers suitable location with

excellent nearby coal resources, road and barge transport accessibility, with adequate

water resources and necessary workforce to construct and operate the facility. Coal

supply would be available from Allied Coal and Phoenix Coal which both operate

nearby, as well as a number of other suppliers operating in Henderson and surrounding

counties. This strong coal supply is a significant asset of the proposed site. Some

additional improvement to basic utility access and connection with high capacity natural

gas and electricity may be required but is possible. The site developer will need to


adequately assess natural and cultural resources and manage the site to avoid negative

impact to those resources.

Solar

Adequate solar radiation is critical to the successful generation of solar power. A

successful site should be relatively free from land cover, and not within a mile of a

corporate city boundary. The Penn Virginia Area A site has an annual direct normal

solar radiation of 3.88 KWh/m2/day and an annual solar radiation for two-axis flat plates

of 6.18 KWh/m2/day. Based upon this average solar radiation, too much cloud cover

and haze is present to be effective as a large scale facility. The property is open land

except for the forested ridges. Solar installations in large mass can be a visual

distraction to local communities; however, this site is greater than a mile from an urban

community.

Wind

The most critical component for a successful wind facility is adequate and consistent

wind speed. In order to generate enough power to be a utility class facility, a mean

average wind speed at 60 meters of 5.6 meters per second (m/s) or greater is required.

Information obtained from AWS Truewind, indicates that the average wind speed at 60

meters for the site is 5.27 m/s. Without adequate wind speed, other factors, such as

foundational concerns, potential visual impacts, telecommunication interference,

impacts to birds and bats, as well as operational concerns such as ice shedding, noise,

blade drop and throw, and flicker are moot. Wind speed measurements to accurately

assess the available resource at any potential development site would be required prior

to final planning.

Mean wind speed – 5.27 m/s


Biomass

An adequate feedstock supply environment includes available crop residues, animal

manure, forest residues from former silviculture or clearing, primary and secondary mill

residues, urban residues (i.e., wood scraps from local business such as lumberyards),

landfill gas, domestic wastewater, or switchgrass. Information obtained from the

National Renewable Energy Laboratory indicates that the total biomass available within

Henderson County is 127,465 tonnes/year. Biomass in Henderson and its surrounding

Counties is 829,150 tonnes/year. These supplies (>500,000 tonnes/year) are expected

to provide an adequate feedstock source. Analysis of the potential in the area to grow

feedstock specifically for a biomass facility should also be part of the planning process.

Nuclear

A limiting factor to the development of a nuclear facility is available water supply. The

lowest mean annual flow for this section of the Green River is 3,453 MGD, which is well

above the required 11.5 MGD to meet basic facility needs.

Safety issues associated with nuclear facilities include ensuring an adequate controlled

buffer zone of at least 2,000’ radius around the facility and an effective emergency plan.

These aspects mean that the best location for a nuclear facility is a rural, or

undeveloped site. The Penn Virginia Area A site has a controlled exclusion zone

greater than 3,000’, but is located 10 miles from a population center of 25,000 persons

or more. The emergency plan should take into account egress limitations that could

potentially impede emergency efforts. No obvious impediments to egress are present

within 50 miles of the site. From the site, egress on the Audubon Parkway can be taken

either east to Owensboro or west to Henderson. From either city, egress can continue

in the same direction or north and south using Hwy 431, Pennyrile Parkway, or Natcher

Parkway.

Atmospheric considerations can be important for a nuclear facility to avoid the possibility

for interaction of the nuclear cooling system plume with a plume containing noxious or


toxic substances from a nearby facility. The nearest air pollutant discharge source is a

source for air emissions six miles from the site.

SUITABILITY

In summary, the Penn Virginia Area A, located within the Western Kentucky Coal Fields,

is a viable site for a potential alternative energy facility, particularly a biomass or

CTL/CTG facility. The site scored a total of 1026 points, representing 86% of the total

available points for a CTL/CTG facility. Similarly, for a biomass facility, the site scored a

total of 1061 points, representing 85% of the total available points, with good

transportation and high biomass availability in the local area. The Penn Virginia A site

offers suitable location with excellent nearby coal resources, road and barge transport

accessibility, with adequate water resources and necessary workforce to construct and

operate the facility. Some additional improvement to basic utility access and connection

with high capacity natural gas and electricity may be required, but is possible. The site

developer will need to adequately assess natural and cultural resources and manage

the site to avoid negative impact to those resources

Due to a low average mean wind speed, this location is not a viable location for a utility

scale wind facility. Additionally, available solar radiation at the site is too low to produce

a significant source of energy for a utility solar facility alone, with a site score of 542

points, representing 58% of the total available points.

The site scored a total of 704 points for a potential nuclear facility, representing 73% of

the total available points. Prior to development of a nuclear facility, foundation concerns

and further geotechnical study would be required for earthquake stability.
