APPLICATION FOR A CERTIFICATE OF ENVIRONMENTAL COMPATIBILITY AND PUBLIC NEED

COMES NOW Entergy Arkansas, Inc. (%AI'' or the "Company"), and for its

Application for a Certificate of Environmental Compatibility and Public Need,

states:

DESCRIPTION OF THE COMPANY

1. EA1 is a corporation organized under the laws of the State of

Arkansas, and is a public utility, as defined by Act 324 of 1935, as amended and

codified at Ark. Code Ann. § 23-1-101 et seq. The Company's property consists

of facilities for the generation, transmission, and distribution of electric power and

energy to retail and wholesale customers. These facilities are located principally

in the State of Arkansas. As of December 31, 2001, the Company provided retail

electrical service subject to the jurisdiction of the Arkansas Public Service

Commission ("APSC" or the "Commission") to a total of 648,226 customers. Of

these customers, 547,980 were residential; 77,503 were commercial; 22,241

were industrial; and 502 were public agencies or institutions.

2. EA1 owns or operates five large oil and gas-fueled steam electric

generation stations, four coal-fueled generating units, four combustion turbine

generating units, one diesel electric unit, two hydroelectric plants, and two

nuclear generating units, for a total owned generating capacity of approximately

5,041 MW.

3. EA1 also owns and operates approximately 935 circuit miles of

extra high voltage transmission line of 345 kV or greater; 260 circuit miles of

transmission line of 230 kV; 3,450 circuit miles of transmission lines of 161 kV

and lower; transmission substations; distribution substations; and associated

facilities necessary to provide electric service.

JURISDICTION AND APPLICABLE LAW

4. EA1 is a public utility subject to the jurisdiction of the Commission.

The proposed facilities that are the subject of this Application constitute a ''major

utility facility" within the meaning of the Utility Facility Environmental and

Economic Protection Act, codified at Ark. Code Ann. Q 23-18-501 et seq. (the

"Major Facilities Act"). This Application is, therefore, being filed pursuant to the

Major Facilities Act and Rules 2, 4, and 7.09 of the Commission's Rules of

Practice and Procedure ("RPP").

PROPOSED ELECTRICAL FACILITIES

5. EA1 proposes to construct and operate a new, 500 kV switching

station, two 500 kV line segments of approximately 1.5 miles in length each

(7,800 feet), and related facilities in Mississippi County, Arkansas (the "Proposed

Electrical Facilities"). The Proposed Electrical Facilities are more fully described

in EA1 Application Exhibits A, B, C, and - D. EA1 Application Exhibit A shows the

route of the transmission line and indicates the location of the Proposed

Electrical Facilities. EA1 Application Exhibit B shows the Proposed Electrical

Facilities along with EAl's local area electrical system. EA1 Application Exhibit C

shows the Proposed Electrical Facilities along with the Company's regional area

electrical system. EA1 Application Exhibit D is a detailed description of the

Proposed Electrical Facilities.

6. The Proposed Electrical Facilities will include a new 500 kV

switching station ("Sans Souci 500 kV Switching Station") to be built on a site

near Osceola, Arkansas at Sans Souci, which site has been secured with a

purchase option by Plum Point Energy Associates, LLC ("PPEA"), an affiliate of

LS Power Development, LLC. Two new connecting segments of 500 kV

transmission line will be built from the new Sans Souci 500 kV Switching Station

to the existing Dell 500 kV Substation to the Shelby 500 kV Substation

Transmission Line (the "Dell-Shelby 500 kV Transmission Line").

7. The Company projects a life expectancy of 40 years for the

Proposed Electrical Facilities based upon periodical depreciation studies that

estimate the remaining life of transmission lines and other facilities depending on

the maintenance and improvements performed on them. If the transmission line

- 3 -

is abandoned, EA1 will remove the conductors and structures from the right of

way. Any salvaged material will be sold as scrap and the right-of-way will revert

to the owners. The estimated cost in current dollars to remove the transmission

line and transmission facilities is approximately $1.5 million, with salvage values

less than $500,000. Reuse of transmission type material is very unlikely due to

possible contamination or possible damage to the material during removal.

PROPOSED AND ALTERNATE ROUTES

8. The transmission line route consists of a corridor, approximately

320 feet in width, extending southwest from the proposed Sans Souci 500 kV

Switching Station, which will accommodate two 500 kV transmission line

segments within the right-of-way, that will connect to the existing 500 kV

transmission grid some 1.5 miles (7,800 feet) southwest of the proposed Sans

Souci 500 kV Switching Station site (the “Proposed Route”). The proposed Sans

Souci 500 kV Switching Station is located in the N% of the NE% of Section 24 at

Township 12 North (“T-l2-N”), Range 10 East (“R-1 0-E”), Mississippi County,

Arkansas. The proposed 500 kV line segments will run southwest and connect

with the existing Dell-Shelby 500 kV Transmission Line in the SEX of the NE% of

Section 26, T-12-N, R-1 0-E, Mississippi County, Arkansas.

The centerline of each 500 kV line segment connecting the proposed

Sans Souci 500 kV Switching Station to the EA1 transmission grid is further

described in more detail in EA1 Application Exhibit D, pages 1 through 3.

The proposed Sans Souci 500 kV Switching Station will encompass

approximately 28 acres. The site is bounded on the east by Ditch No. 11, on the

south by Arkansas State Highway 198, on the west by a defined property

- 4 -

boundary and the Burlington Northern Santa Fe (“BNSF”) mainline railroad track,

and on the north by the BNSF spur track.

9. An alternate transmission line route to the east, measuring

approximately 3.1 miles (16,500 feet), connects to the Dell-Shelby 500 kV

Transmission Line. This route requires the relocation of the proposed 500 kV

Switching Station site to the east of the preferred site and northeast of Arkansas

State Highways 239 and 198. The alternate route parallels drainage ditches for

the most of the way and begins at the alternate Sans Souci 500 kV Switching

Station site located in the SE% of the SEX of Section 18 at T-12-NI R-1 1-E,

Mississippi County, Arkansas. This alternate route is described in more detail in

EA1 Application Exhibit D, pages 3 and 4.

10. The Proposed Route is the shorter route for the Proposed Electrical

Facilities, is the route preferred by the single landowner who would be affected,

crosses the least amount of agricultural land, and parallels the existing linear

features. In addition, all real estate rights for the Proposed Route have been

secured by PPEA from the single landowner.

NEED FOR PROPOSED ELECTRICAL FACILITIES

11. PPEA is developing a new merchant power coal-fired g n rating

station (“Plum Point Energy Station”) in Mississippi County and has requested

interconnecting service with the Company’s transmission grid. The maximum

generating capacity of the Plum Point Energy Station is being designed to

accommodate up to 1,600 MW of output and may include up to two steam

turbine generator sets. The Proposed Electrical Facilities are required to allow

- 5 -

PPEA to export power from the facility to the electrical grid for sale to wholesale

customers. PPEA intends to apply for exempt wholesale generator status, and

EA1 is required by federal law to provide access to the Company's transmission

facilities, upon reasonable terms and conditions, for an exempt wholesale

generator.

COST AND METHOD OF FINANCING

12. The total project cost of the Proposed Electrical Facilities is

estimated to be: $(million)

500 kV Transmission Segments

500 kV Switching Station

Relay and Communications

Corporate Loading

$3.9 8.0 0.2 1.4

Total $20.5

PPEA will reimburse EA1 for the costs of interconnecting its power plant with

EAl's transmission facilities, as provided for in the applicable Federal Energy

Regulatory Commission regulations and in Rule 3.6(a) of the APSC's

Cogeneration Rules, and as specifically agreed to in the Interconnection

Agreement negotiated by PPEA and the Company, which is filed herewith as - EA1

Exhibit JPZ-1 to the Direct Testimony of Mr. John P. Zimmerman. PPEA will pay

EA1 for the cost of the Interconnection Facilities through Contributions in Aid of

Construction so that these facilities will have no effect on EAl's retail rate base or

- 6 -

rates. See, Direct Testimony of Company witness Mr. Gregory R. Zakrzewski,

filed in this Docket.

ECONOMIC IMPACT UPON THE COMMUNITY. ~-

THE COMPANY~ AND ITS CUSTOMERS '

13. Construction of the Proposed Electrical Facilities will have little

direct economic impact upon the local community through increased employment

or through impacts upon agriculture. Construction of a substation or

transmission line requires a specialized crew, and it is not expected that workers

with the appropriate skills and experience will be available from the local

economy for the project. Thus, the construction of the proposed transmission

line will not significantly increase employment opportunities for workers in the

area.

14. Although the Preferred Route will cross active agricultural lands for

all of its length, clearing the lands in this area will be minimal and most of the

route that passes through farmland follows section and quarter-section lines, field

edges, and/or property lines to minimize effects on cultivated fields, farming

operations and crop production. The Proposed Route follows the BNSF mainline

railroad track for its entire length on the west boundary and follows a portion of

U.S. Highway 61 immediately west of the connecting point to the Dell-Shelby 500

kV Transmission Line. However, because transmission line construction is

scheduled to commence in the first quarter of 2005, very little crop loss can be

expected as a result of construction activities. In addition, an agreement

regarding the purchase of real estate is in place between PPEA and the

landowner. More information about the economic impacts on the local

-7-

community are contained in the Environmental Impact Statement ("EIS"), which

is filed with the Direct Testimony of Company witness Mr. Thomas A. Varhol as

EA1 Exhibit TAV-2.

15. The economic impact of the project on EA1 and its customers will

not be significant. The total estimated investment in the Proposed Electrical

Facilities is approximately $20.5 million, which compares to the Company's total

transmission net plant in-service balance of approximately $864 million' as of

December 31, 2001. As noted above, the interconnection costs

associated with the Proposed Electrical Facilities will be borne by PPEA and will

not be reflected in EAl's regulated rates.

16. Although the economic impact of the Proposed Electrical Facilities

may be minimal, they are essential to the operation of the PPEA facility, which

should have a significant positive impact on the local economy. It is anticipated

that up to as many as 800 workers will be employed during the construction of

the facility, which will produce additional funds to be spent locally for labor and

material. Once the plant is in operation, it is anticipated to have up to

approximately 125 employees, resulting in increased spendable income to the

local area for goods and services.

FERC Form No. 1, December 31,2001, at 207 1

ENVIRONMENTAL IMPACT

17. Once operational, the proposed Sans Souci 500 kV Switching

Station and transmission line segments will have little, if any, adverse impacts on

the surrounding environment. The Company retained the services of Black and

Veatch Corporation of Overland Park, Kansas, to review the project

requirements, and to recommend a preferred route from the pre-selected line

routes, and to prepare an EIS for the Proposed Electrical Facilities and alternate

transmission line routes. Additionally, PPEA retained Burns & McDonnell,

Engineers-Architects-Consultants of Kansas City, Missouri, to perform a Phase I

Cultural Resources Investigation. The results of the investigation are discussed

in the EIS and the Direct Testimony of Mr. Eric W. Crawford, the PPEA Project

Manager. The Proposed Route parallels a mainline railroad track and in general

follows property boundary lines and field edges and, therefore, avoids

residences, thereby minimizing the impacts on environmentally sensitive areas.

The Proposed Route also minimizes the visual impact of the line and its impact

on wetlands and forested areas by using modular structure designs.

continues parallel to the southeast property line of the Burlington Northern

Santa Fe Railway (“BNSF”) right-of-way, being located approximately 90

feet southeast of said southeast property line of the Burlington Northern

Santa Fe Railway right-of-way. The proposed western-most line segment

continues southwest for approximately 3,700 feet (0.66 mile) where it

crosses State Highway 198. Approximately 1,500 feet (0.28 miles)

southwest of Arkansas State Highway 198, the line segment crosses

Sandy Bayou (Ditch No. 9). South of the Sandy Bayou crossing, the

western-most line segment then crosses through approximately 1 ,I 00 feet

(0.21 miles) of storage area and, at this point, parallels both the BNSF

railroad track and U.S. Highway 61. The line segment then crosses

another 1,500 feet (0.28 miles) of agricultural land before crossing farm

drainage Ditch No. 16 and intersecting with the tie-in point at a new

structure on the existing Dell-Shelby 500 kV Line located in the SE % of

the NE % of Section 26, T-12-N, R-10-E, Mississippi County, Arkansas.

ditches for the most of the way and begins at the alternate Sans Souci

500 kV Switching Station site located in the SEX of the SEX of Section

18 at T-12-N, R-11-E, Mississippi County, Arkansas. The alternate 500

kV line segments will exit the proposed alternate Sans Souci 500 kV

Substation site to the west and will cross over Brown Bayou and Arkansas

State Highway 239 while running parallel and to the north of the BNSF rail

spur for approximately 3,400 feet (0.6 mile). It then makes a 90-degree

turn to the south at an unnumbered farm ditch. The alternate route then

extends to the south for approximately 10,500 feet (2.0 miles) while

paralleling a portion of Ditch No. 10 and crossing Sandy Bayou (Ditch No.

9) - At the intersection of the south section line of Section 30, the route

then makes a 90-degree turn to the west. It proceeds west along the

section line for approximately 1,200 feet (0.2 mile), where it makes

another 90-degree turn, and proceeds due south for approximately 1,400

feet (0.3 mile) to intersect with EAl’s existing Dell-Shelby 500 kV

Transmission Line located in the NEX of the NE% of Section 36, T-12-N,

R-I 0-E, Mississippi County, Arkansas.

Structures

The 500 kV overhead, three-phase, shielded, single circuit electrical

transmission lines will be sumorted bv two and three Dole. steel structures. These


1 structures will consist of tangent structures and guyed dead-end structures. The

2 attached photographs show the general appearance of these structures. The proposed

3 lines will consist mostly of tangent structures with dead-end structures at each end of

4 each segment. All structures will meet or exceed requirements of the National

5 Electrical Safety Code (‘“ESC”) with applicable overloads.

6 The 500 kV tangent structures will be a two pole, H-frame type structures

7 designed to meet the loading requirements specified above, varying in height

depending on clearance requirements. Each of the three phases will be supported by

polymer V-string insulators, one set of V-string insulators per phase, approximately 14

feet long. The phases will be in a horizontal (flat) configuration on both sections of the

new lines. Each of the 500 kV line segments will have two shield wires supported by

hardware located near the pole tops. The poles will be attached to cylindrical concrete

caisson type foundation embedded in the earth at varying depths depending on soil

conditions and foundation loads. Depending on soil conditions, alternate foundations

such as 20 to 30 foot long piles may be required.

The 500 kV large angle and dead-end structures will be a 3-pole, designed to

meet the specified loading conditions, varying in length, with a polymer post insulator to

support the conductor connections around the pole if required by the line angle. The

shield wire and conductors will be attached directly to the pole with connecting

hardware. Down guys will be utilized as necessary to accommodate the transverse and

longitudinal loads imposed by the conductors and shield wires and to provide structural

stability. Down guys will be attached to an anchoring system designed to

accommodate the guy loads and the soil conditions. The poles will be attached to

cylindrical concrete caisson type foundation embedded in the earth at varying depths

depending on soil conditions and foundation loads.

Insulators

The insulators will be polymer/fiberglass units designed to support the loading

specified by the NESC. V-string (two polymer insulators yoked together in a V shape to

support the conductor) will be used on the tangent structures, and polymer strain

insulators will be used on the dead-ends.

The spans for the 500 kV line will average between 600 and 1100 feet. The

minimum conductor to ground for the 500 kV line will be 40 feet. Where electrical

distribution or communication lines are crossed, a clearance of 20 feet will be

maintained for a conductor operating temperature of 176" F. The 500 kV spans

crossing the railroad will have a minimum conductor to top of rail clearance of 45 feet.

Terminal Point - Sans Souci 500 kV Switching Station

The proposed Sans Souci 500 kV Switching Station facility will be a new 500 kV, 4

breaker switching station constructed immediately adjacent to the Plum Point Energy

Station site, on property to be provided by Plum Point Energy Associates, LLC

("PPEA"). This switching station will be owned and operated by EAI. The switching

station will be configured as a "ring-bus" with 3-phase gas-insulated 5-inch aluminum

pipe bus arranged in a horizontal configuration. Bus phases will be spaced 30 feet apart

horizontally. The proposed switching station will be designed as a low profile facility.

The tallest structures within the fenced switching station will be the dead-end structures

for the 500 kV transmission line terminations and takeoffs, and the lightning shielding

structures. These structures should not exceed 100 feet in height.

The Sans Souci 500 kV Switching Station will have four separate line positions in

the ring bus. One line segment in-coming and one line segment out-going fromlto the

existing EA1 Dell-Shelby Transmission Line, and two lines connecting the PPEA power

plant output feeds. Each line position will be protected by a set of two, 500 kV power

circuit breakers (Le. there will be one circuit breaker between each line position, for a

total of four breakers), in what is commonly called a “ring-bus” protection scheme. A set

of two motor-operated disconnect switches will be installed at each breaker (one on

each side) to provide isolation ability.

A dedicated relay and control building will be constructed in the switching station

to house the power, controls, and monitoring equipment required to operate the

substation locally. Cables to/from the control house to the various equipment

components will be routed via direct buried conduit duct banks and in engineered cable

trenches. Communications between the Sans Souci 500 kV switching Station and the

Dell 500 kV Substation and the Shelby 500 kV Substation will be transmitted via carrier

wave signals on the 500 kV transmission line conductors.

All structures and equipment in the Sans Souci 500 kV Switching Station (with

the exception of the circuit breakers) will be supported on augured pier concrete

foundations. The circuit breakers will be supported on concrete pad foundations.

Equipment and bus within the substation will be supported on galvanized tubular steel

structures, connected via embedded anchor bolts to the augured pier foundations

described above. The entire switching station site will be fenced with an 8-foot chain

link fence. Emergency lighting will be provided in the event maintenance must occur at

night.

contractor crews under the supervision of ESI personnel in a sequential operation of

surveying, clearing, foundation installation, structure erection, conductor installation and

clean-up.

The first operation is to survey the route to establish the centerline, edge of right-

of-way, and profile of the transmission line. Primarily, only men and small items of

equipment will be required for surveying. Centerline staking and profiling may require

cutting some trees and undergrowth, if necessary. No new access roads will be

established for survey crews.

Right-of-way clearing, if necessary, will be performed by EA1 construction crews

or by a contractor under the supervision of EA1 personnel to ensure that the clearing is

done as specified. Trees that may exist outside of the right-of-way which endanger the

safe and reliable operation of the transmission line will be cut to provide necessary

clearance.

Structure installation takes place in three phases: transporting, assembling, and

erecting. Necessary material is transported by flatbed tractor-trailer from a storage yard

to each structure location and is unloaded with a small crane or boom truck. The

structures are assembled, as much as is practical, on the ground; the poles are then set

in augured holes with a tracked or rubber-tired crane. The holes will be backfilled with

concrete. Final hardware connections will then be completed.

Conductor stringing is accomplished with tensioning equipment to keep the

conductor from contacting the ground or other objects which may damage it. A pulling

22 line is installed on the structures in stringing blocks from a puller to the tensioner. The

EA1 Application Exhibit D - U Docket No. 02-

1 reels of conductor are mounted on reel stands and the conductor is threaded through

2 the tensioner and attached to the pulling line. The puller operates to pull the conductor

3 while the tensioner operates to maintain the proper tension.

4 Conductor installation is a critical operation. Many vehicles and items of

5 equipment are required to install the conductor; and, although they may not necessarily

6 proceed down the right-of-way, they must intermittently be positioned on it. As with

7 vehicles and equipment associated with other construction phases, care will be

8 exercised to minimize damage to the terrain.

Re: Proposed 500 kV Sans Souci Switching Station and 500 kV Transmission Lines

IN THE MATTER OF THE APPLICATION OF ENTERGY ARKANSAS, INC. FOR A CERTIFICATE OF ENVIRONMENTAL COMPATIBILITY AND PUBLIC NEED TO CONSTRUCT AND OPERATE THE SANS SOUCl500 KV SUBSTATION AND RELATED 500 KV TRANSMISSION LINE AND ASSOCIATED TRANSMISSION FACILITIES, IN MISSISSIPPI COUNTY, ARKANSAS

Dear [ Title Name 1:

This is to inform you pursuant to Ark. Code Ann. 8 23-18-513 and Rule 3.03(b)(3) and 7.09 of the Arkansas Public Service Commission (APSC) Rules of Practice and Procedure, that on or about Thursday, March 28, 2002 (the Application Filing Date), Entergy Arkansas, Inc. (EM) filed an application with the APSC for permission to construct a 500,000 volt electric transmission line and a related 500 kV switching station (Proposed Electrical Facilities) in Mississippi County, Arkansas. The Proposed Electrical Facilities consist of:

a four-element, 500 kV ring-bus switching station which terminates two generator output source feeds from a new generating station and connects with the EA1 transmission grid through two parallel 500 kV transmission line segments that extend south from the switching station for a total of approximately 1.5 miles (7,800 ft.) located in Sections 24 and 26 in Township 12 North (T-l2-N), Range 10 East (R-lO-E), Mississippi County, Arkansas.

The Proposed Electrical Facilities are more fully described as follows.

Sans Souci 500 kV Switching Station - The proposed Sans Souci 500 kV Switching Station will be a new 500 kV, 4 breaker ring-bus switching station constructed on property immediately adjacent to and westlsouthwest of the Plum Point Energy Station, on property to be provided by Plum Point Energy Associates, LLC (PPEA). This switching station will be owned and operated by EAI. The switching station design will be configured as a "ring-bus" with 3-phase

Letter of Notice (con?) March 28,2002

gas-insulated 5-inch aluminum pipe bus arranged in a horizontal configuration. Bus phases will be spaced 30 feet apart horizontally.

The Sans Souci 500 kV Switching Station will have four separate line positions in the ring-bus. One line segment in-coming and one line segment out-going fromlto the EA1 Dell 500 kV Substation to Shelby 500 kV Substation Transmission Line (Dell-Shelby 500 kV Transmission Line), and two lines connecting the Plum Point Energy Station output feeds. Each line position will be protected by a set of two, 500 kV power circuit breakers (i.e. there will be one circuit breaker between each line position, for a total of four breakers), in what is commonly called a "breaker and a halt" protection scheme. A set of two motor-operated disconnect switches will be installed at each breaker (one on each side) to provide isolation ability.

A dedicated relay and control building will be constructed in the switching station to house the power, controls, and monitoring equipment required to operate the switching station locally. Cables tolfrom the control house to the various equipment components will be routed via direct buried conduit duct banks and in engineered cable trenches. Communications between the Sans Souci 500 kV Switching Station and the Dell 500 kV Substation and the Shelby 500 kV Substation will be transmitted via carrier wave signals on the 500 kV transmission line conductors.

Sans Souci 500 kV Switching Station to the Existing DellShelby 500 kV Transmission Line - The proposed two parallel line segments to be connected from the Sans Souci 500 kV Switching Station to the Dell-Shelby 500 kV Transmission Line, begin at the proposed EA1 Sans Souci 500 kV Switching Station, located in the N% of the NE% of Section 24 in T-12-N, R-lO-E, and exit the switching station to the south and extend southwest for approximately 1.5 miles (7,800 feet) paralleling the southeast property line of the Burlington Northern Santa Fe Railway (BNSF) right-of-way. The two parallel 500 kV transmission line segments are located approximately 90 feet and approximately 230 feet southeast of said southeast property line of the BNSF right-of-way. The proposed 500 kV line segments continue southwest along the BNSF, crossing Arkansas State Highway 198, Sandy Bayou (Ditch No. 9) and Ditch No. 16, and then intersect with the tie-in structure at the existing Dell-Shelby 500 kV Transmission Line located in the SE % of the NE % of Section 26, T-12-N, R-10- E, Mississippi County, Arkansas.

Information related to the Company's application may be obtained from the Secretary of the APSC, 1000 Center Street, Little Rock, Arkansas 72201, during normal business hours. A copy of the Application and related filing documents along with the Environmental Impact Statement associated with this proposed project is included in this notice for your inspection.

The enclosed map portrays the approximate location of the proposed transmission segment routes and the proposed switching station. The sites were selected after careful environmental, economic and engineering consideration. Also enclosed are drawings of the typical transmission line structures that illustrate the appearance of the tubular steel pole structures to be used in the construction of this line.

Letter of Notice (con’t) March 28,2002

The APSC will conduct a hearing in connection with EAI’s Application for a Certificate of Environmental Compatibility and PubIic Need. Interventions and limited appearances for interested persons should be in compliance with provisions of APSC Rule 3.04 and Ark. Code Ann. f j 23-18-517. Petitions for intervention or limited appearance must be filed with the APSC within 30 days after the Application Filing Date unless good cause is shown pursuant to Ark. Code Ann. f j 23-1 8-5 17.

A public hearing date will be set by the APSC not less than 40 days nor more than 90 days after the Application Filing Date. The public hearing will be held at the APSC Building in Little Rock, Arkansas, located at 1000 Center Street. The purpose of the hearing will be for the Commission to hear evidence of the general economic and environmental impact of the proposed project, and to choose the best location with the least generally adverse economic and environmental consequences. In the course of selecting a route location for the proposed transmission facilities, the Commission may modify the proposed location if it is in the public interest. Compensation for any damages will not be awarded by the Commission, but may be awarded by Circuit Court in an eminent domain proceeding, if the applicant and the landowner cannot settle privately.

I would be pleased to provide any additional information you may need concerning the Proposed Electrical Facilities. My telephone number is (50 1) 377-4457.

Sincerely yours,

Steven K. Strickland Vice President, Regulatory Affairs - Arkansas
