1.0 Executive Summary f

Aero-Data Corporation (ADC) has contracted with the Entergy River Bend Station to conduct a photo mission covering at least a five mile radius around.the facility near St. Francisville, Louisiana. ADC has been l providing annual plant site documentation of the facility since 1985.

! This year ADC was requested to produce photographs of the facility, and a I photomosaic. The current photography was compared to the previous years photography in order to identify any changes in the number of wellheads and/or pipelines surrounding the site. Changes in vegetation within the l facility boundary were also identified.

l The deliverables for this project include contact prints of each frame (23), a color plot showing the 1995-1996 changes, a color plot containing the frame center for each of the photographs from the current flight, and l

l this interpretation repon.

1 1.1 Methods and Materials The current photo mission was flown on September 23,1996 at a scale of 1"=1,500' using false color infrared (CIR) film. The coverage area of the ,

l I

flight increased from the previous year to five miles around the reactor.

In order to easily cover the increased area, the flightlines were changed slightly. Therefore, the frame centers' of the 1996 photographic coverage differ slightly from those flown by ADC in 1994 and 1995. The previous l

photo mission was flown on October 6,1995 also at a scale of 1"=1,500' l and using CIR film. ADC's flight planning was simplified with the use of a Geographic Information System (GIS) software package which aided in the alignment of the flight lines. Using this system, seven flightlines were selected and 91 frames of film were shot for this photo mission.

Navigation was conducted using GPS navigation and moving map equipment.

Contact prints for the current photomission were produced at a scale of 1 "=1,500' . The prints for the current and 1995 dates were analyzed on a large mirror stereoscope for change detection.

The change map of the River Bend facility was produced using a Geographic l

Information System. The GIS incorporated computer scanned imagery of

the 1995 and 1996 photo missions as well as digitized vector data.

Comparison of the current photography with the 1995 photography by photointerpretation revealed no new changes regarding pipelines or wellheads. No significant ground vegetation removal was detected.

1 ADC also constructed a map showing the frame centers, frame numbers, end latitude / longitude coordinates of each frame. This map was created l

from 1990 TIGER digital line data acquired from the U.S. Department of I Commerce, Bureau of the Census in CD-ROM format. The Tiger data is useful for reference purposes, supplementing the.optdated U.S. Geological Survey 7.5 minute quadrangle map data available for the area of interest I (the Port Hudson quad map was last updated in 1980; the St. Francisville

quad in 1972). In terms of accuracy, the scale of TIGER data is 1:100,000 and may be anywhere from 50 to 140 feet off; whereas the 7.5 minute quads have a scale of 1:24,000 and may be up to 40 feet off.

i Aero-Data can map the area from the current photography and produce a l

current map which will surpass the accuracy of USGS quadrangle sheets should it be requested. The above referenced map should be used to select the specific frames which provide coverage within the site area. l l 1.2 Summary of Preliminary Findings No changes in the number or size of wellheads, pipelines or transmission line right-of-ways were identified during the interpretive phase of this project. There are no significant changes in vegetation in the area immediately surrounding the cooling towers. The vegetation in the area surrounding the cooling towers has not changed significantly in the last 5 years. Some construction activities are visible to the east of the immediate plant area. This construction appears to be a parking area and

a new building. Aside from this construction, the area surrounding the Entergy River Bend facility has not changed significantly since the 1995 photomission.
