ABSTRACT
This report presents an analysis of aerial photography covering the approximate
1,210 acre Mountain Pine Pressure study area, located south of Plainview, Arkansas,
in the west central part of the state. Thirteen selected dates of black-and-white,
and one date of conventional color aerial photography acquired over a 51-year
(1938-1988) period were used to perform the analysis. This analysis was performed
to monitor and document physical conditions and activities that could lead to the
contamination of the surrounding environment; specifically surface and/or ground
water.
The lumber mill was first observed to be operational on the 1960 photography,
and remained active through the 1984 photo coverage. Flooding was visible in the
southern portion of the study area on the 1973, 1974', and 1984 photos. The small
pond, which was first observed on the 1967 photo, and the probable preserving unit,
which was first observed on the 1966 photo, had staining associated with them
throughout most photo coverages. The largest pond, which had sheen and possible
seepage on the 1988 photo, was first observed on the 1973 photo. The first on-site
disposal of solid waste was noted on the 1973 photo, and this practice continued
through the 1988 coverage. Expansion and new construction at the lumber mill was
noted on the photo coverages of 1966 and 1973. The 1988 photo coverage showed the
lumber mill was no longer operational, as indicated by the lack of finished and raw
materials, the dilapidated facilities, and active filling of the pond.
The U.S. Environmental Protection Agency's Environmental Monitoring Systems
Laboratory in Las Vegas, Nevada, prepared this report for the Agency's Environmental
Services Division in Region 6 at Dallas, Texas and the Office of Emergency and
Remedial Response in Washington, D.C.

INTRODUCTION
This report presents an analysis of aerial photography covering the Mountain
Pine Pressure study area located south of Plainview, Arkansas (Figures 1 and 2).
Thirteen selected dates of black-and-white panchromatic, and one date of
conventional color aerial photography (Table 1) acquired over a 51-year period
(1938-1988) were used to perform the analysis. These analyses were performed to
monitor physical conditions and activities that could lead to contamination of the
surrounding environment; specifically surface and/or ground water.
The study area outlines portrayed on the map and photos were provided by the
Region and do not necessarily reflect legal property boundaries.
The U.S. Environmental Protection Agency's Environmental Monitoring Systems
Laboratory in Las Vegas, Nevada, prepared this report for the Agency's Environmental
Services Division in Region 6 at Dallas, Texas and the Office of Emergency and
Remedial Response in Washington, D.C.

METHODOLOGY
Stereoscopic pairs of current and historical aerial photographs are used to
perform the analysis. Stereo viewing enhances the interpretation because it allows
the analyst to observe the vertical as well as horizontal spatial relationships of
natural and cultural features. Stereoscopy is also an aid in distinguishing between
various shapes, tones, textures, and colors that can be found within the study area.
Evidence of waste burial is a prime consideration when conducting a hazardous
waste analysis. Leachate or seepage resulting from burial and dumping of hazardous
materials might threaten existing surface or ground-water sources. Pools of
unexplained liquid are routinely noted because they can indicate seepage from buried
wastes that may enter drainage channels and allow contaminants to move off the
site. An excellent indicator of how well hazardous materials are being handled at a
site is the presence or absence of spills, spill stains, and vegetation damage.
Trees and other forms of vegetation that exhibit a marked color difference from
surrounding members of the same species are labeled "dead," "stressed," or "damaged"
based upon the degree of noticeable variation. Vegetation is so labeled only after
consideration of the season in which the photographs were acquired.
The U.S. Environmental Protection Agency's Statement of Procedures on
Floodplain Management and Wetlands Protection (Executive Orders 11988 and 11990,
respectively) requires EPA to determine if removal or remedial actions at hazardous
waste sites will affect wetlands or floodplains and to avoid or minimize adverse
impacts on those areas. To aid in compliance with these orders, significant wetland
areas located within and adjacent to the sites have been identified and delineated.
However, the sites have not been visited to verify the accuracy of wetland
identification.
Drainage analysis determines the direction a spill or surface runoff would
follow. Direction of drainage is determined from analysis of the photographs and
from U.S. Geological Survey topographic maps. Whenever they are available,
7.5-minute quadrangle maps (scale 1:24,000) are used to show site location and to
provide geographic and topographic information.

ANALYSIS SUMMARY
The Mountain Pine Pressure study area is located in the west central part of
Arkansas on the south side of Plainview. The approximate 1,210 acre area is
basically flat farmland with a slight southerly slope. Porter Creek located just
outside the study area's west boundary, Prairie Creek located in the western portion
of the area, and an unnamed intermittent stream located in the eastern portion of
the area provide the drainage from the study area. Most of area C is subject to
flooding as evidenced by the inundation on the photo coverages of 1984, 1974, and
1973.
The photo coverages of 1938 and 1950 showed the study area prior to
construction of the lumber mill on the souther edge of Plainveiw. The photo
coverage of 1960 displayed a fully operational lumber mill at this location,
including a small unlined pond and mounded material near the northern drainage into
Porter Creek. There was no significant change noted on the photo coverage of 1962.
The 1966 photo coverage showed the expansion of facilities at the lumber mill
including the enlargement of several buildings, the construction of new buildings,
and expansion of open storage space. Small amounts of standing liquid and stains
were present throughout the facility. The 1967 photo showed a new unlined pond and
minor construction activity at the lumber mill. There was no significant change in
the remainder of the study area. The February 1973 photography again showed no
changes in the study area, except at the lumber mill where several new buildings had
been constructed, the unlined pond had been enlarged, a new pond built, and a small
amount of solid waste was located near the new pond. Staining was visible at the
preserving unit and on the bank of the smaller pond. The March 1973 photo showed
flooding of the study area's southern portion. Stains were still visible near the
pond and the preserving unit, and the pile of solid waste had increased in size.
The 1974 photography showed no change from the previous coverage. The 1979 photo
showed the southern portion of the study area again inundated. The largest pond may
have overflown its southern wall, and the small pond had been enlarged. Solid waste
dumping continued near the largest pond. Expansion of the wood preserving unit was
5
-------
noted to include additional tanks and kilns. The 1983 photographs showed once again
the only change to occur in the study area was in the lumber mill where a probable
wood preserving unit was observed and a T-head pier type structure had been
constructed in the largest pond. The January 1984 photography showed the study area
had not changed. Staining was again noted at the same locations, on site solid
waste disposal continued, and the unlined ponds still contained dark liquid. The
1988 photography indicated the lumber mill was no longer operational, and clean-up
activity was in progress. The pond which had staining on most photo coverages was
being filled with dirt obtained from a mound located just north of the solid waste
dump. Also located at the mill were seven horizontal and four vertical uncontained
tanks, and four contained vertical tanks, of which one had collapsed. The largest
pond had sheen along its bank and possible seepage was noted at its southeast wall.
The remainder of the study area was virtually unchanged since first observed on the
1938 photography.

DECEMBER 16, 1960 (FIGURE 6)
This photo shows an operational lumber mill located at the northern edge of
area A on the southwest edge of Plainview. The mill consists of a sawhouse and
green chain (Annotation 1), an incinerator (Annotation 2), a curved roof building
(Annotation 3), a group of three connected quonset huts (Annotation 4), a small flat
roofed building (Annotation 5), a small administrative buildings (Annotation 6), and
open storage. There is a small unlined waste pond, and mounded material that
appears to be wood chips/saw dust, located along the northern drainage into Porter
Creek. All surface runoff from this area would travel northwest into Porter Creek
then south to Fourche La Fave River. Surface runoff south of Annotation B will
follow the natural drainage pattern of Prairie Creek or the unnamed intermittent
stream along the areas eastern boundary which travel south to Fourche La Fave River.

OCTOBER 20, 19 66 (FIGURE 9)
No significant changes are noted in the area C area of the Mountain Pine
Pressure study area since the 1960 photo coverage. The following changes are noted
in the northern portions of areas A and B.
Annotation 3:
This building has been enlarged with an addition along its
south side, and the small building which is connected to the
north has also been enlarged.
Annotation 4:
What appears to be a covered loading dock has been constructed
on the west side of the quonset huts, and a small addition
built onto its north end.
Annotation 7:
This is a new building, probably a preserving unit. There is
a drainage ditch beginning near the buildings southeast
corner, where ground staining is present, and extends west
around the edge of the open storage area to the natural
drainage leading to Porter Creek.
Annotat ions
8 and 9:
These are new small flat roofed administrative type buildings,
Annotation 10:
This is an area previously occupied by a residential structure
that has been razed and the area is now being used for open
storage.
Annotation 11:
This is a new building with an aerial conveyor to the
incinerator.
The open storage area has more than tripled in size, and there are small
amounts of standing liquid and stains located throughout.

FEBRUARY 20, 1973 (FIGURES 12 AND 13)
These photos show no significant change to the area C area of the Mountain
Pine Pressure study area since the photo coverage of 1960. The following changes
are visible in the lumber mill at area B and the northern portion of area A.
Annotation 3: This building has been remodeled and now has a gable roof.
Annotation 5: The building previously located here, has been razed and a new
smaller building constructed in its place.
Annotation 7: An addition has been constructed at the east end of this
building, and there are two cylindrical tank like objects
connecting the buildings. A small amount of staining is
visible on the west side of the building, where two kilns are
also noted.
Annotation 12: This is an area in the natural drainage pattern that has been
filled.
Annotations 13,
14, 15, and 16: These are new buildings, the functions of which are
indeterminate.
Annotation 17: This unlined pond has been enlarged to about double its
previously observed size. There is dark staining on the east
bank, and on the north bank where lumber is stacked. The
drainage ditch along the south side of the pond now begins
near the southeast corner of the building at Annotation 8, and
a small area of disturbed ground is noted near the end of the
ditch.
Annotation 18: This is a newly created pond that is not lined and contains
liquid.
Annotation 19: This is a pile of solid waste that may be the result of the
clearing activity in the area.

MARCH 21, 1973 (FIGURE 14)
This photo shows no significant change in area C of the Mountain Pine Pressure
study area since the February 20, 1973 photo coverage. The southern portion of the
area and the Porter Creek basin are inundated. The numerous small wet areas
located throughout the lumber mill were most likely caused by heavy rainfall.
Dark staining is again visible at the west end of this
building.
Staining is again noted on the northern bank of this pond
where lumber is stacked, and in the ponds southwest corner.
This pile of solid waste has slightly increased in size.

MARCH 6, 1979 (FIGURE 16)
This photo shows no significant change has occurred in the area C of Mountain
Pine Pressure study area since the 1973 photo coverage. Once again the southern
portion of this area, and the Porter Creek basin are inundated. The following
changes are noted at the lumber mill located in areas A and B.
Annotation 3:
This building has been partially dismantled. Sections from
the east and south sides of the building have been removed.
Annotation 7:
A new section, a kiln, and three vertical tanks have been
constructed to the north side of the original building, and
there are now five horizontal tanks between the two
buildings. Staining is still present on the west side of the
building.
Annotation 14: The northern portion of this building is being dismantled.
Annotation 17:
This unlined pond has been enlarged and approximately half of
the liquid contained in the pond is very dark colored.
Annotation 18:
This pond is filled to capacity and may have overflown its
southeastern wall prior to this photo. Beginning at the
southeast edge of the pond and extending in a southeast
direction into and around a small impoundment, most of the
vegetation has the appearance of being pushed to the ground by
flowing water.
Annotation 19:
This solid waste dumping area has increased in size. There
are light, medium, and dark toned materials being dumped in
the area then mixed and spread.

FEBRUARY 24, 1988 (FIGURE 22)
The visible activity at this installation indicates the facility is no longer
operational. There are no finished products in the open storage, no raw materials
storage, one of the ponds is being filled, and the buildings are in a poor state of
repair.
Annotation 3: The roof and western walls of this dilapidated building have
collapsed.
Annotation 7: This wood treatment unit is non-operational. The four
vertical and four horizontal tanks have no secondary
containment. Product spillage from these tanks would enter
the drainage ditch along the building's south side. This
ditch leads directly to Porter Creek on the west side of the
study area. The ditch now has a temporary earthen dam holding
back mud colored liquid immediately south of the filling
activity at Annotation 17.
Annotation 17: The unlined pond previously at this location is being filled.
It appears the fill dirt is obtained from the excavation of
the mound just north of the solid waste dumping (Annotation
19). The fill dirt is being stockpiled at three locations
around the pond which is approximately two-thirds filled.
Cover soil is being spread over what appears to be a white
lining covering the filled eastern portion of the pond. Two
open-topped tanks are located at the southern edge of the pond
area being filled. Black material is mounded at the base of
the tanks arid extends down the slope into the fill area. A
small earthen dam has been built across the drainage ditch
located along the south side of this area. This portion of
the ditch, which contains muddy colored liquid, has been
dredged and the material placed along its southern bank.
46
-------
Annotation 18: There is a small amount of sheen at two locations along the
eastern bank of this pond. The track activity near the pier
and two other locations along the western edge of the pond
appears to be the beginnings of bank improvements. The
vehicle tracks on top of the wall around the southern portion
of the pond, end at a location where there are three small
areas of possible seepage from the pond.
Annotation 19: Solid waste dumping has continued in the northern portion of
this area where old tires and other debris are visible. Most
of the piles of solid waste in the southern portion are
becoming overgrown. A dozer has graded the top soil back from
around the excavation north of the dumping area.
Annotation 20: This facility no longer appears operational. One of the four
vertical tanks on the east side of the building has collapsed
and the hard surfaced open storage yard is empty. A makeshift
drainage ditch extends west from the south side of the
building and connects to the main ditch south of the pond.
