1.0 SUMMARY
Vicinity Property No. CA-401
Remedial action was completed on Vicinity Property CA-401. A total of
752.6 cubic yards of material was removed from the property.
Radiological surveys conducted following removal of contaminated
materials, but before property restoration, demonstrate that the property
has been cleaned up to the EPA standards. This completion report
recommends certification of the property as having been cleaned up to
below the EPA standards.
2.0 OPERATIONS SUMMARY
2.1 Remedial Action Plan
The basic remedial action on this property was performed according to
the Remedial Action Plan. A total of 752.6 cubic yards of material
was removed from the property, compared with an estimated excavation
of 280 cubic yards.
2.2 Previously Unidentified Contamination
Areas B, C, N, and N were larger than estimated, and Area N required
excavation to greater depths than estimated.
2.3 Unanticipated Items During Remedial Action
No unanticipated items occurred during remedial action on this
property.
3.0 VERIFICATION SUMMARY
3.1 Radiological Survey Data
All survey data were acquired according to approved procedures.
3.1.1 Pro-Remedial Action Survey
The results of the survey defining the contaminated area
requiring remedial action are presented on Drawing
CA-401-015.
3.1.2 Pro-Restoration Survey
Exterior:
After removal of contamination, and prior to backfilling, a
soil sample survey was conducted in the excavated areas.
Soil samples were aliquoted from each of the 25
verification grids and analyzed by gamma spectroscopy with
the opposed crystal system in accordance with Health
Physics Procedure 015. The radium concentrations in these
soil samples ranged from less than 1.3 to 5.9 pCi/g, as
described in Table 3.1.
5345F -4-
^ .: . 4 .- ^. ., „ , __ ^

Vicinity Property No. CA-401
Outdoor gamma readings in the excavated area ranged from 11
to 13 micro R/hr. The readings are given in Table 3.2.
Drawings CA-401-020, CA-401-021, and CA-401-022 show the
actual areas of excavation.
These results confirm that exterior contamination has been
reduced to levels below the EPA standards for radium in
soil. Background for the Canonsburg site is 8 to 11 micro
R/hr and 1.2 pCi/g.
Interior:
Remedial action was performed indoors only in Building 14A
on this property. A gamma scan in the excavated regions
showed gamma levels up to a maximum of 12 micro R/hr, which
is less than the EPA standard of background plus 20 micro
R/hr. These results are described in Table 3.2.
"Grab" radon daughter concentration (RDC) measurements were
made in 4 locations, as described in Table 3.4. These
measurements were made under standard conditions as
described in the VPMIM. Measurements were not made in
Building 14A as close-up conditions cannot be met.
3.2 Recommendation for Certification
3.2.1 Exterior:
3.2.2 Interior:
Fourteen areas of contamination were identified and
removed. Soil samples after excavation and prior to
backfilling indicate that the limits of 5 pCi/g in the
surface 15 cm. and 15 pCi/g in any 15 cm. layer below the
surface are not exceeded. Based on this information, we
recommend that the exterior of this vicinity property be
certified to be in compliance with EPA standards for the
UNTRA Project.
Remedial action was conducted in the structure. All gammu
readings taken in the structure following remedial action
were less than the 20 micro R/hr above background limit.
Radon daughter concentrations are below the 0.01 WL limit
for grab samples. Based on this information, we reconmend
that the interior be certified to be within the limits of
the EPA standards for the UNTRA Project.

The enclosed report of the V.C.A. milling practice and
development for carnotite ores at Naturita and Mexican Hat
has been written from the V.C.A. report submitted to your
office, from personal notes and also personal observations
during my term of service with the V.C.A.
I have endeavored to present an unbiased report and to present
the data and observation in the best light possible.
M.any of the troubles and problems incidental to test work
have not been mentioned and as nearly as possible the fiscal
results of the V.C.A. work and developments presented.
I have drawn freely upon the technical reports you left in
Grand Junction on scrubbers and their use in comparison of
the ¥teirni scrubber with other known scrubbers.
It is my opinion that if the investment atiounts mentioned
by V.C.A. as being spent on tie concentration process were
compared with those stated in their concentration report, it
Aould be found that a large proportion of the EifiOunt was
invested in the form of rehabilitation of their salt roast-
*.G soda leach vanadium plant at Naturita which is being operated
specifically for raw ore treatment.
Do you wish to have V.C.A.'s report returned to you in Washington?

SUMARiY OF MILIJNG OPkiATIONS rLY V.U.A.
The Vanadium Corporation of America conduc ted sandl slilbe concentration tests
at the Naturita plant fronm July, 1946 to May, 1947. The essentials of the
method used were crushing carnotite ores, grindinrt the ore in pebble mills
or rod mills, scrubbing the ground ores in an attrition machine developed by
Mr. A.J. Weinig, separating the sands and slimes by conventiontal cassi' fiCa.tioln
methods, settling the slimes and filtering the slimes. The above method used
by the V.C.A. is commonly known as the sand-slime concentration of carnotite
ores .
The Vanadium Corporation of America constructed and used two concentration
plants usini the sand-sli.me concentration method. The metallurtjical results
from both of these plants did not achieve the recoveries end ratios of concentration
indicated by test work and pilot plant work.
The concentrator at Naturita treated both carnotite ores and roscoelite ores,
and the mletallurgical results were a 3:1 ratio of concentration with a 75%
recovery of the vanadium. This concentrator was dismantled and the parts
sh.ipped to Mexican ilat, Utah where a similar concentrator was erected. The
plant at .,!exican ib.t treated ores from tht% Navajo Reservation. The carnotite
in this region occurs in the shinarump conglomerates which for efficient concenltyrtion
require a ntodified treatnrent from t}hat cf the method used on the
uniforrm size sai.nd grair ores treated at Naturita. However, tU:e plant at ?,lexican
Hat is virtually a duplication of the Naturita plant. The mietallurgical results
frowm t.,e fiexican |iit mill are approximately 60' recovery of tr.e metal values at
a 7:1 ratio of concentration. The work indicated an 80% recovery with a 10:1
ratio of concentration.
The scrubber as developed by the Vanadium Corporetion was not used in any continuous
oper~ating mill. It was found in the plant scale testing to be restricted
in its use, anad the excessive wear on parts was not, satisfactorily solved.
The Vanenimilm Cor-oration did not, develorp any nac i;. Li.ods of ' St- -oimlfu,, 1 rJis,fication.

ORES USED LY V.I ...
The V.C.A. Corporation conducted laboratiory scale sand slime ep; ration tests
at Bridgeville, Pennsylvania fron April, 1944 to December, 1945. The concentration
tests consisted of carnotite ore scrubbing by continuous circui ation
through centrifugal laboratory pumps. Also, during this period, laborat 0or
roesting and lesching tests were conducted on the slime concentraticns to uetermine
their amenability to the salt roast and soda ash leach process. The
laboratory results obtained encouraged the V.C.A Corporation to conduct experimental
work for the development of a scrubber suitable for plant operation.
This phase was carried on at the experimental plant of the Colorado School of
Mines at Golden, Colorado under the direction of' Messrs. Weinig and Sproul from
April, 194A to January, 1945. The result of this work w.s the developement of
the Weinig scr.bber.
Three scrubbers, six inches in diameter, twelve inches in diameter, and twentyfour
inches in diameter were developed. The scrubber that was developed consisted
of two rubber discs, one of which is stationary, and the second fastened
to a rotating shaft. The operation of the machine depenes upon the admission
of an ore ;rrlp through the center of the stationary rubber disc. The ore pulp
is then forced beetv.een the two rubber discs by centrifugal force and Pmping
action. The scrubber operates with many of the characteristics of a centrifugal
p1ll p ·
Two types of' macilines were developed, a horizontal scrubber and a vertical scrubber.
both machines proved to behave metallurgically in a similar manner and
with like poser consumption (30-22 H.P. Hr. per ton). Difficulty ;as experienced
in obtaining rubber scrubbing plates having a long life.
Minor acterations were made to the VCA Vansdium Plant at Niturita, Colorado, and

pabble mill reaainned us the basic grinding unit while five scrubbing devices
were tried. They were:
(1) Horizontal scrubber with sleeve bearings.
(2) Horizontal scrubber with ball bearings.
(3) Vertical Scrubber.
(4) Rubber covered rod mill.
(5) Wilfley pump as a scrubber.
The pilot plant work deternlned that scrubbing efficiency is dependent upon the
ore grind, coarser grinds requiring excessive amounts of scrubbing for re:asonable
recoveries. It was determined that the Wilfley pump was an efficient scrubber,
and that it was possible to achieve 33% recovery by pebble mill grinding with the
use of Wilfley pumps as scrubbers.
The rubber covered rod mill was used for a scrubbing unit and indicated tnat
82/% recovery of vanadium could be achieved, and that in view of the performance
of the Weinig scrubber that an additional increment of vanadium recovery might
be obtained by restricted application of a single Weinig unit to the tailing of
a rubber rod nill.
The use of pine poles as a grinding media yielded negative results. A comparison
ta.ble of the results' obtained on pilot plant concentration testing is included.
Througifnot all of thie test work, the V.C.A. report indicates insufficient classifier
capacity.

It is interesting to note that with the methods; as usei. tiii- ratio as ue t :.aterially
improved over the ratios of concentration reported by Siegfrieda lisler
in 1912. The average extraction for all batch pilot plant tests was 79.3Ah of
the vanadium, and 8A.4.1% of the U30. The Standard Cne:.iical Coipany reports a
recovery of 88.6% of the U308 for the period of 1)19 throagh 19l2.
Continuous milling operations were started in January, 1947, and continued until
April 30, 1947. For this continuous milling operation, the Weinig scrubber was
not used. The flow sheet consisted of crushing the ore, grinding in a 3 x b rod
mill charged with steel rods, and classifying with a drag classifier and Akins
classifier in series, the classifier overflow was further classified in a 9'
Callow cone. During the period of continuous operation, the avwage grade of
concentrate was s approximately 5'% V2O, and the average recovery was i.,proxir:tely
75; V2 0 5 at a concentration ratio o 3 to 1. The mill was ouer.ted at a feed
rate of thirty-five tons per day. Both carnotite and roscoelite ores were concentrated.
The slime concentrates were laundered to settling ponds,. After the
mill tng prorTanm h% d been completed, the concentrates were allowed to settle and
dry,, ,nd wer, thien treated in the operating vanadium mill. It was found th-.t the
sodluza cnrl-ionate added to the grind circuit improved tile recovery of vanadiutn.
It . ns thoullt t tthis hhlt was due to the deflocculation of' the slimes drin.- classl
lcti ion. Tne 7 ;tinlnard Chemical Conpany, in 1919 deter.lined ;Jalso that the addition
of soda ash to a slime-sand concentration circuit was beneficial. No data
was gatihered daring the V.C.A. operations as to the affect of mill water t ;nperaturRs
!1'lon recoverj. efficiencies.
lTe "ilPVl::/ puirps were included in the contiguous concentration circuit as scrubrnern,
and are shown on the attached flow sheet. Each pump in the circuit indicated
the P.rfect of decreasing the vanadliuna value in the a.zids by 0.1l V 20 5 8pproachin(r
a limni, f ' residuial vanadium of 0.25% V205.

All of the mill equipment with the exception of two ore in s sia two ore
Covyeyors was used equipment from the pilot plant testing worx- at Naturit..
Laboratory testing of the Mexican Hat ores indicated 75% to 80o, recoveries of
the vanadium and uranium in a slime concentrate, however, due to poor classification
and poorly controlled grinding, the Mexica-n Hat concentra:tor of tne V.C.A.
has achieved recoveries in the order of 60% of the values. This concentrator was.
ooerated at q rate of forty-five tons of ore feed per day, tie i;rinding meia was
2' diameter steel rods. The laboratory work indicated the proper media to be
pebbles or smnall steel balls. The two continuous concentration plaints evolved
from all plant testing work at Naturita consisted in tne final form of c(rusililg
the ore, grinding the crushed ore in an open circuit mill with steel rods, Wad
classifying tahe ground ore with drag classifiers. No scrubbers other than
Rifl.ev jlumr. Were used in either the Naturita continuous plant or the :Aexican
Hat plaint. The final flow sheets of these two concentrators taerefore does not
differ materially from the nethods used in concentration units oper!iting in this
same field during the early 1900's.

Subject: Ri;SFPCHl AND OP-11ATING COSTS OF V.C.A. CONCW:TuiATIOI PROG(AM
Symbol P:MGM
A study was made of the detailed co-ts for the V.C.A. research
program on concentration methods during my visit to the V.C.A.
offices in New York May 17, 1948.
The costs presented by the V.C.A. w.ere grouped as laboratory
research work, and experimental work at Golden, Colorado leading
tc tie development of the WeiniE scrubber, batch testing at
Naturita, operation of the continuous concentrator at Naturite,
and operation of the Mexican Hat concentrator. The grouping of
tlhe costs in this manner shows the amount spent on each phase of
the work, and affords a clearer understanding than the summbry table
slhovn in Mr. Bransome's letter of March 19, 1948.
I hrfveyrranged some of the costs, especially overhead expenses, to
conforr with the different phases of their research program. This was
done in accordance with the atteched letter received f'romn r. LrLnd
the V.C.A. comptroller. At the time of the visit to the hew York offices
of V.C.A., I did not ask for a further trezc.dcwn of costs otner
t1isn the grouping as shown on the attached report, out it is my Delief
that this method of showirn the costs is sufficiently eccurate
to esteblish the values of the work they have done on concentration.

Subject: RI;SEAFPCH AND OPERATING COSTS OF V.C.A. CONCETRATION PRO(;AM
Symbol: P:MGM
A study was made of the detailed coets for the V.C.A. research
program on concentration methods during my visit to the V.C.A.
offices in New York May 17, 1948.
The costs presented by the V.C.A. t.ere grouped as laboratory
research work, and experimental work at Golden, Colorado leading
tc tie development of the Weinig scrubber, batch testing at
Naturita, operation of the continuous concentrator at Naturite,
and operation of the Mexican Hat concentrator. The grouping of
the costs in this manner shows the amount spent on each phase of
the work, and affords a clearer understanding than the summa.ry table
shoin in Mr. Bransome's letter of March 19, 1948.
I havezrrranged some of the costs, especially overhead expenses, to
conform with the different phases of their research program. This was
done in accordance with the attached letter received from Mr. Brand
the V.C.A. comptroller. At the time of the visit to the New York offices
of V.C.A., I did not ask for a further kreakdcwn of costs other
tisn the grouping as shown on the attached report, but it is my belief
that this method of showing the costs is sufficiently accurate
to establish the values of the work they have done on concentration.
While visiting the AEC offices in New York, qr. Merritt advised me
that similar negotiations hed been conducted with the V.C.A. by the
New York group some time previously, and that the Niew York Raw Materials
group had rejected the V.C.A. proposal of the sale of their
concertration process.
After compiling the breakdovn of the V.C.A. cost;, it is mry opinion
that the only true research work they coudlctt'd w'ias ta.t of the lti:toratory
at Bridgeville the eyperimental work at Go].enr, Col:rlido,

;anb)ol: BM:Fm;3:PA
' The modern accepted laboratory research practice to develop the lowest cost
and most efficient method of mineral dressing is, first, to attempt ccnce:tration
of the ore minerals, with subsequent treatment of the concentrated
product. It is only after thorough research efforts of concentration have
failed thAt treatment of the total ore is considered. The benefits cf
conceritra.tio.n are several-fold and include lower plant initial capital in-
: vestment End lower plant operating costs as the major achievements.
2> Problens related to the concentration of the Colorado Plateau urniuL.-vL'.Cai-i
ores ehocild receive the same consideration that is normally awarded mineral
dressir.q- reseorch efforts directed toward the concentration of any type of ore.
Cotnceltrast.ion of the Colorado Plateau ores is not new, as an early stidy of the
- occ-urewc of the uranium and vanadium minerals disclosed the fact that concelntration
c.-,uld be obtained by grinding the sandstone to individual grai. size to
liber-. The uranium and vanadium minerals. Attrition grinding and scrubbing
of th}e rrd .Frains was found effective in liberating the vcnad.iu : a urnl-l^-
; S.n su-r.,-:;uernt separation of the sands End elir.es resulted in an appreciatel
- cocceutration of the ore minerals in the slime portion.
Fon 1 919 to 1923, approximately 22,000 tons of ore were xiternittently
,l '3.ed in a 35 ton per day plant by wet grinding and classification. It is
r orto. that initial recovery of the uranium was approximately 78o, with a
:1 rutLio of concentration. Retreetment of the weathered teilings from this
. oerbton yielded an ardditional 10.6% recovery, reking en ovFrw.l recover.' of
: 8:.6%. The high ure-niui, recovcry is a reflection of the high race c.re
rilled rather than the effiiciency of meat:d employed.
In recent years the Vanadium Corporation of America attempted devcloi-mnt
of a new rethod of mechanical colcentration by the use of s bcubcors on he
ground ore pulp. This conpany should be awarded credit for revivirg interest
in concentration of these ores.
At a meeting in your office, Mr. Bransome, President oi VCA, outlined the
invest igtions his company had conducted .o find a solution to efficiently
concentrate these ores. It was suggested by us that the AEC woulc consicer
a plan whereby VCA would be reimbursed for expenses incurred in the developrcnt
cf its concentration project, providing a thorough ir.vestigaticn by r te
AEC proved such reimbursement justified. FurLher discussion of a general
nature 4xcluded the possibility of employing VGA to desirn, b.iidc, sad roerctea,

i suBJEr: COI'CNTRATION OF CARNOTITE OBES BY VANADIUM CORPTATION OF A RICA
Mr. Bransome telephoned this office from New York and said he was willing to
send us a complete report covering all phases of investigations and the research
work his company had performed. It was definitely stated that we could
not accept this report if in so doing we were committed in any way. Mr.
Bra.some. assured us that his company was completely covered through patent applications
and that the Commission assumed no obligations through receiving
this report.
The report sent by Mr. Bransome was accompanied by a letter showing an expenditure,
related to the development of the VCA concentration project, of
:186,661.94. This report was thoroughly reviewed by both of us and the New
Y:ork office of the Raw Materials Division. An investigation was made of available
literature pertaining to this subject. The concentration work done by
- V A can be broken down into the following divisions:
1. Research work at the.Bridgeville, Pennsylvania laboratory. (July 1944
through September 1946.)
2. Research work at the Colorado School of Mines Experimental Station,
under the direction of Mr. Arthur Weinig. (July 1944 through January
1948.)
3. Batch testing of concentration methods at Naturita to January 1947.
4. Operation of a 35-ton continuous pilot concentrator at Naturita.
Jenuary 1947 thru April 1947.
5. Mixed c icentrate-ore roasting operations on plant scale at Naturita.
6. Construction and operation of a 50-ton concentrator at Mexican Hat
VCA submitted to us a figure of $252,452.43 for the total cost of their concentration
program. A breakdown of these costs is attached to this memo.
A review of the work done under the VCA concentration i .ject quite definitely
indicated that the work following batch testing at Naturita was not related
to research work for the development of a concentration process. This phese
of the work was not well directed and is not in the channel in which v;e are
particularly interested. The research work done at Bridgeville and under the
supervision of Weinig, together with the batch testing at Naturits, was well
done. The actual cost for this work was as follows:

It is proposed that VCA be paid the sum of $50,000 which is less than 50% of
the actu?. cost of this work. Approximately $27,000.00 was spent nt the
Colorado School of Mines under the supervision of Arthur Weinig. It i3 believed
tl}t this phrase of work done for VCA was capably performed and probably at a
lower cost thsn the AEC could have had it done.
The following proposition was discussed with Mr. Bransome in New York on June
3, 1948: In consideration of the sum of $50,000.00 paid by the AEC to VCA for
the work performed, VCA will sell to AEC certain patent rights, metallurgical
resul.ts, "khow-how", and all other data pertaining to the subject of mechanical
concentration of carnotite and roscoelite ores.
It was rather difficult to appraise the money value of the VCA work, as it was
- . indicated more eaphasis should have been put on attrition grinding rather than
on scrubbing; however, the Colorado School of Mine;,. atte-npte to develop a
scrubber for theoe ores, and as 'r. Weinig is an outstrand',g - lemell.r;.>al
engineer and has been a practicing metallurgist in the State of Co ,.oro for
over 40 years, he undoubtelly selected this method of concentr.tion as: prer-:)ting
a more favorable solution than attrition grinding.
The offer of the VCA is liberal and we believe the AEC will be cuomen.atted for
this expenditure by obtaining the VGA concentration report alorng iithl t.he
"know-how" of its technical staff and through discussion with M!r. '1eini .
The proposed expenditure of t50,00J0.00 appears to be justified by the obtainng
of a substauitial portion of a carnotite ore dressing program in +he fotrm of
complete-l research work by a reput.able company. The value of parents ncw hr'ld
or possibly granted to VCA do not appear as important to the A-FC as the "knowhow"
and results obtained from their concentration projeet.

PLANT, BRIDGEVILLE, PA
This site conducted work for the Manhattan Engineer District in the
early to mid 1940's to support processing being performed at several sites
covered under the uranium mill tailings Remedial Action program. These
include Canonsburg, Naturita and Mexican Hat.
The facility was utilized to grind pitchblende ore being processed at
Canonsburg. The material was trucked under guard from Vitro Canonsburg to
the Bridgeville plant, was ground and generally returned the same day.
Records suggest in at least one instance the material was stored at
Bridegville over night. The material was highgrade pitchblende (greater
than 50% U308 and the uranium was in equilibrium with its daughters).
It was processed in quantities of hundreds of tons at a time. The period
of time the processing was performed is not known.
The site also conducted developed research for the VCA processing
plants at Naturita and Mexican Hat. The work was paid for by the
government and was conducted between July 1944 and September 1946. The
work included lao and benchscale separation tests and roasting and
leaching testing on western ores from the Naturita or Mexican Hat area.
Atomic Energy Commission Memoranda from the period contain detailed
discussions concerning the work and its relation to the western milling
operations and whether or not the Commission should pay for the research.
They ultimately decided that the research was in direct support of
Commission projects and paid for the research.
Site Location
The site was located near Bridgeville, Pennsylvania off PA Route 50
near Interstate 79 about 6 miles southwest of Pittsburgh. It is located
in Collier Township at Kirwan Heights. The plant is now owned by Cyclops
Corporation and is in an industrial area near a General Electric glass
plant. The location of the plant with respect to Canonsburg is shown in

Location Number: (CA00401)

INTRODUCTION
Location Number: CA00401
An inclusion radiological survey of location CA00401 was conducted on September
27, 1985 by Oak Ridge National Laboratory. This property, located
at Mayer Street, is classified as a commercial manufacturer. This survey
was conducted using methods as defined in the Vicinity Properties
Management and Implementation Manual, UMTRA-DOE/AL-050601 (June 1984) and
the RASA UMTRA Procedures Manual (June 1985). General location information
is provided in Table 1, radiological survey results are given in Table 2
and 3, and supporting graphics are provided in Figure 1. Different views
of the property are provided in Figures 2 through 10. All measurements are
gross readings; background has not been subtracted.
The conversion formula used is y = x/CF, where 'y' equals the exposure rate
in iR/h, 'x' equals the scintillometer measurements in kcpm, and 'CF'
equals the conversions factor determined in the field through a direct
correlation between PIC and scintillometer measurements in kcpm/CiR/h. For
this property, CF equals 2.
SIGNIFICANCE OF FINDINGS
The nineteen contaminated regions found outdoors in scattered areas about
the vanadium parcel of the property as shown on Figure 1, encompass -3600
m2. The high outdoor gamma (300 pR/h) was measured in a 965 m 2 area of the
*large parking lot northwest of the ore storage and shipping building
(building #2), Region L. Regions C, D, L, and P, as noted on Figure 1,
were found to exceed the outdoor gamma inclusion criterion of background
plus 25 pR/h when averaged over an area of 100 m2. Many of these regions
had scattered contaminated material within its boundaries. Elevated gamma
levels were also spotty in Regions A, K, and O, as noted on Figure 1.
Elevated gamma levels ranging from 20 to 30 pIR/h, found northwest of building
#14A, are the result of natural radiation inherent in phosphate residues.
In addition, gamma levels ranging from 16 to 30 pR/h, found in a
slag dump west of Region D, are due to scattered pieces of ore in the pile;
whereas, gamma levels south of Region P (14-18 pR/h), are the result of
natural radiation inherent in gravel and rock material. Three point
sources scanning 100, 80, and 70 pR/h, were found north of Region 0, east
of Region 0, and north of Region M, respectively, as denoted by an asterisk
on Figure 1. Indoor gamma scans were not conducted since outdoor contamination
deemed the property includable.
The results of the radionuclide analyses demonstrate that the net areaweighted
average concentration of 2 2 6 Ra in the surface soil at locations
S15 (Region Q) and S16 (Region M), are 25 and 5 pCi/g, respectively.
Furthermore, if the mean 2 26Ra concentrations are calculated from surface
samples taken in Regions A, D, L, and P, their respective net area-weighted
averages are 20, 7.4, 54, and 14 pCi/g. These values exceed the surface
soil inclusion criterion of 5 pCi/g above background when averaged over an
area of 100 m2.
Based on these screening results, it is recommended that location CA00401
be included for further consideration by the UMTRA Project.

RECOMMENDED FOR: Inclusion

DETERMINATION OF AUTHORITY TO CONDUCT REMEMDIAL ACTION
BRIDGEVILLE (VCA) SITE - BRIDGEVILLE, PENNSYLVANIA
The purpose of this letter is to provide an interim response to
your request for Aerospace review of the Report of Inclusion Survey
at Location CA0401, Mayer Street, Bridgeville, Pennsylvania, dated
December 1985; and to examine the considerations necessary to determine
if the Department has authority to conduct remedial action at
the site of the former Vanadium Corporation of America (VCA) Bridgeville
laboratory facility.
The results of the Inclusion Survey referenced above are sufficient
to indicate that the levels of residual radioactive contamination on the
site exceed the criteria requiring remedial action under both FUSRAP and
UMTRAP. The question that must be resolved concerns the Department's
authority to conduct remedial action at this site.
There are three scenarios that warrant consideration in determining
if the Department has authority to conduct remedial action at the site.
The first concerns work done by VCA at their Bridgeville facility in
support of operations at the Canonsburg Site. Documents dated in October
and November 1943 indicate that African ore was ground at the Bridgeville
facility in preparation for processing at the Vitro plant in Canonsburg,
PA. The ore, packaged in drums, was delivered from storage to the
Bridgeville facility by truck, was ground and repackaged in the same
drums. The drums were covered with burlap and delivered to the plant
in Canonsburg the same day that the ore was ground. These actions were
apparently carried out under guard and witnessed by several parties.
Therefore, the propensity for loss of significant quantities of this
material seems remote. Furthermore, it is reasonable to assume that any
residual radioactive material from the processing of this high grade ore
would be in the form of surface contamination which, over the years, may
have mixed with soil, but it would not be expected to be in the form of
a tailings pile. Approximately five lots of ore were known to have been
ground. The quantity of ore ground is unknown except for indications
that there were 45 drums in Lot 1.
An Affirmative Action Employer

Mr. L.C. Brazley 2 20 March 1986
The second indication of involvement between AEC and the work done
at the Bridgeville facility is a research project carried out by VCA
to improve methods for the mechanical concentration of carnotite ores.
Although information is limited, it is apparent that the AEC was interested
in obtaining the "know-how" of the VCA technical staff and the
results from their concentration project so that the methods and data
could be used as a starting point for an AEC carnotite ore dressing or
concentration research program.
Research work on this project was carried out at the Bridgeville site
during the period July 1944 through 1946. Experimental work and pilot
plant testing of the methods developed was done at Golden, Colorado, and
the VCA Mexican Hat and Naturita plants through late 1947. Compilation
of costs incurred during the project indicate that less than 10% of the
total project cost of approximately $100,000.00 was attributed to work
done at the Bridgeville facility. Therefore, if we accept the premise
that only laboratory bench scale testing was done at Bridgeville, and
use project cost as an indicator of the volume of material (ore and/or
ore concentrates) processed, it is logical to assume that the quantity
of residual radioactive material that might be attributed to the project
would be small compared to the total volume of tailings deposited at the
site over the years by VCA. Another factor pertinent to the consideration
of AEC involvement is that their (AEC) interest in the work apparently did
not materialize until the spring of 1948. Furthermore, the proposed AEC
expenditure of $50,000.00 was to obtain "...a substantial portion of a
carnotite ore dressing program in the form of completed research work by
a reputable company." There is no indication in the documents reviewed
of any AEC involvement in the work until after the project was completed.
Although somewhat remote, there is a possibility that the Bridgeville
site might have been used as a holding or storage area for VCA concentrates
(50% slimes) from their Monticello and Naturita plants. It is known that
all these concentrates were processed at Vitro Manufacturing Company's
plant in Canonsburg. Available information would indicate that these
concentrates were shipped directly from the western sites to the Canonsburg
plant. However, it is possible that the VCA facility in Bridgeville, less
than twenty road miles from the Canonsburg plant, could have been used as a
holding area for these concentrates. As previously indicated, documentation
to confirm this scenario has not been found.
Sufficient historical documentation has not been found to clearly define
MED/AEC involvement in the operations at the Bridgeville site. Therefore,
as has been discussed with you and with ORNL representatives, the only
avenue available for determining if the Department has authority to conduct
remedial action at this site is through laboratory analysis of the samples
collected during the Inclusion Survey. The presence of significant quantities
of highgrade pitchblende characteristic of the African ores or of
ore/concentrates identifiable with the Monticello, Mexican Hat or Naturita
sites would suggest authority for remedial action under UMTRAP. Absent a

Mr. I..C. Brazley 3 20 March 1986
correlation between the laboratory analyses and the scenarios described
above, the Department might consider refering the site to EPA for consideration
as a candidate for the Superfund Program.
Further consideration of this matter by Aerospace will be held in
abeyance until the results of the laboratory analyses are available.
In the meantime, I would be happy to respond to any questions or comments
you might have regarding the material presented herein.

SUMMARY FOR THE VCA
(VANADIUM CORPORATION OF AMERICA)
PLANT, BRIDGEVILLE, PA
This site conducted work for the Manhattan Engineer District in the
early to mid 1940's to support processing being performed at several sites
covered under the uranium mill tailings Remedial Action program. These
include Canonsburg, Naturita and Mexican Hat.
The facility was utilizea to grind pitchblende ore being processed at
Canonsburg. The material was trucked under guard from Vitro Canonsburg to
the Bridgeville plant, was ground and generally returned the same day.
Records suggest in at least one instance the material was stored at
Bridegville over night. The material was highgrade pitchblende (greater
than 50% U308 and the uranium was in equilibrium with its daughters).
It was processed in quantities of hundreds of tons at a time. The period
of time the processing was performed is not known.
The site also conducted developed research for the VCA processing
plants at Naturita and Mexican Hat. The work was paid for by the
government and was conducted between July 1944 and September 1946. The
work included lao and benchscale separation tests and roasting and
leaching testing on western ores from the Naturita or Mexican Hat area.
Atomic Energy Commission Memoranda from the period contain detailed
discussions concerning the work and its relation to the western milling
operations and whether or not the Commission should pay for the research.
They ultimately decided that the research was in direct support of
Commission projects and paid for the research.
Site Location
The site was located near Bridgeville, Pennsylvania off PA Route 50
near Interstate 79 about 6 miles southwest of Pittsburgh. It is located
in Collier Township at Kirwan Heights. The plant is now owned by Cyclops
Corporation and is in an industrial area near a General Electric glass
plant. The location of the plant with respect to Canonsburg is shown in
Figure 1.
