The 450-acre Atlas Mine Area is part of the Atlas Asbestos Mine site in Fresno
County, California. The site consists of four geographically distinct areas (the
Atlas Mine Area, the Clear Creek Management Area (CCMA), the Ponding Basin of the
California Aqueduct, and the City of Coalinga). The Atlas Mine Area is on rural land
owned by the Federal government and private parties, and surrounding land is used for
mining, ranching, farming, and recreation. The Mine Area includes three open pit
asbestos mine surfaces, stockpiles of asbestos waste material, an abandoned mill
building, a settling pond, and debris. Construction of an asbestos mill at the Atlas
Mine began in 1962, and onsite asbestos mining and milling activities occured from
1967 to 1979. Approximately three million cubic yards of asbestos ore and asbestos
mill tailings from onsite operations were bulldozed into piles adjacent to the mill
building. In 1976 and 1980, the Atlas Mine was cited for violating asbestos
emissions standards. In early 1980, after detecting elevated levels of asbestos in
water samples from the California Aqueduct, the State concluded that additional
corrective measures were necessary to prevent mine- and mill-generated asbestos from
entering the drainage basins. Further State investigations identified high

concentrations of asbestos in the Mine Area soil, surface water, and air. A 1989
Record of Decision (ROD) for the City of Coalinga Operable Unit addressed cleanup of
asbestos-contaminated soil in Coalinga, California by burying the contaminated material
in a waste management unit with an impermeable cap. This ROD is designed to control
the release of asbestos from the Mine Area. No actions are proposed at this time for
the CCMA or the Ponding Basin of the California Aqueduct. In 1992, EPA will evaluate
the Department of Interior Bureau of Land Management's revised land use plan for CCMA
to determine if the plan is adequate to minimize airborne asbestos emissions, and the
U.S. Bureau of Reclamation and California Department of Waste Resources actions to
minimize airborne emissions from the Ponding Basin to determine if further action is
necessary. Tqe primary contaminant of concern affecting the soil, sediment, debris,
surface water, and air is asbestos, an inorganic.
The selected remedial action for this site includes paving the road through the Mine
Area or implementing an appropriate road maintenance alternative; constructing stream
diversions, sediment trapping dams, and other slope stabilization elements; instituting
a verification sampling plan involving surface water modeling and surface water and
stream bed sampling, as necessary; conducting a revegetation pilot project, and
implementing revegetation if found to be technically feasible and cost-effective;
dismantling the mill building with offsite disposal along with other debris from the
Mine Area; and implementing institutional controls including deed and land use
restrictions, and site access restrictions such as fencing. The estimated present
worth cost for this remedial action is $4,286,000, which includes an annual O&M cost of
$19,000.
PERFORMANCE STANDARDS OR GOALS: All diversion and drainage facilities will be designed
and constructed to accommodate the anticipated volume of precipitation and peak flows
from surface runoff in a 25-year, 24 hour storm. All tailings will be protected from
100-year peak stream flows. Quantification of risk reduction is difficult because
asbestos from natural and disturbed areas will continue to enter the surface water;
however, a verification sampling plan will be implemented to confirm that an

EXECUTIVE SUMMARY
.
Water quality investigations have identified the presence of volatile organic compound (VOC) and
radionuclide contamination of surface water at the Rocky Flats Plant (RFP).
The subject Interim
"
Measures/Interim Remedial Action Plan/Environmental Assessment (IM/IRAP /EA) addresses contaminated
surface water in a portion of the South Wainut Creek drainage basin located within an area identified as
Operable Unit No.2 (OU 2). There is no immediate threat to public heaith and the environment posed by this
surface water contamination. The affected surface water is contained within the plant boundary by existing
detention ponds, and is treated prior to discharge for removal of voiatUe contaminants and suspended
particulates to which radionuclides, if present. are likely to adsorb. However, there is a potential threat and
the Department of Energy (DOE) is implementing this Surface Water 1M/I RAP at the request of the U.S.
Environmental Protection Agency (EPA) and Colorado Department of Health (CDH). Implementation of the
Surface Water 1M/IRA will enhance the DOE's efforts towards containing and managing contaminated surface
water, and will mitigate downgradient migration of contaminants. Another factor in implementing this 1M/IRA
is the length of time it will take to complete the investigations and engineering studies necessary to determine
the finai remedy for OU 2.
In February and March 1990, representatives from DOE, EPA. and CDH met to discuss surface water
IM/IRAs at the RFP site. The resutt of these meetings was a series of agreements, with the concurrence of
all parties. to implement an 1M/IRA for the cleanup of contaminated surface water in OU 2. OU 2 is defined
- .-
in the Environmentai Restoration Federal Facility Agreement and Consent Order (commonly known as the
"Inter-Agency Agreernenr or lAG). and is comprised of several Individual Hazardous Substance Sites (IHSSs)
that were formerly known in aggregate as the 903 Pad, Mound. and East Trenches Areas.
On 26 September 1990, the DOE released for public comment a proposed Surface Water 1M/IRA Plan
and Decision Document for OU 2. In this Plan, specific point source locations in the South Walnut Creek and
Woman Creek drainage basins were proposed for collection of surface water. According to the Plan, surface
water collected in each basin was to be transferred to a treatment facility discharging to the South Walnut

Creek drainage. Comments on the 1M/IRA Plan received during the public comment period. however. revealed
strong opposition to the transfer of radionuclide contaminated seep water from the Woman Creek drainage
.
to the South Walnut Creek drainage.
Opposition was based on the absence of a proven perlormance record for the proposed 1M/IRA
..
treatment facility with respect to radionuclide removal and the potential for treatment process upsets. In
addition. the public voiced strong concern over potential worker and public health risks resulting from
construction activities In the Woman Creek Basin (i.e., atmospheric suspension of radlonuclide-contaminated
dust). In light of these concerns. the DOe and regulatory agencies agreed to eliminate the proposed interbasin
transfer of surface water seeps within this 1M/IRA Plan and to collect and treat Woman Creek seepage under
a separate OU 21M/IRA project. It is expected that the Surface Water 1M/IRA Plan for Woman Creek Basin
can be completed during the summer of 1991. This wUI allow adequate time to conduct bench-scale treatability
studies of radionuclide removal treatment processes. The results of the bench-scale studies will provide a
better assessment of applicable treatment technologies in selection of the preferred 1M/IRA alternative for the
Woman Creek Basin.
The Surface Water 1M/IRA Plan dated 26 September 1990 has thus been modified to focus on collection
and treatment of South Walnut Creek Basin contaminated surlace water. The Plan presented in this document
reflects this modification. In addition to previous consideration of collection of surlace water at stations SW-59
and SW~1. this Plan also proposes collection at a third location designated as SW-132. SW-132 represents
the discharge of a buried. corrugated metal culvert approximately 22S feet downgradient of SW~1. Recent
field surveys and review of as-built site drainage drawings have identified the culvert to be a conduit for flow
from the upper reach of South Walnut Creek within the Perimeter Security Zone (PSZ). Although water quality
data are not available at this newty designated station. its character is expected to be similar to the flow at SW-
61. A flow monitoring and sampling program has recently been initiated at SW-132. This South Walnut Creek
Basin 1M/IRA Plan provides for the collection of all flow from SW-S9. SW~1. and SW-132. except during
infrequent high flow periods resulting from high precipitation events. As discussed herein. the South Walnut

Creek Basin 1M/IRA design flow is SO gallons per minute (gpm). The average annual flow rate from SW-S9.
SW~1. and SW-132 should be less than 20 gpm, however.
.
This 1M/IRA will be conducted in accordance with the Resource Conservation and Recovery Act of 1976
(RCRA), as amended by the Hazardous and Solid Waste Amendments of 1984 (HSWA); the Comprehensive
Environmental Response. Compensation, and liability Act of 1980 (CERCLA), as amended by the Superfund
Amendments and Reauthorization Act of 1986, the National Environmental Policy Act (NEPA) of 1969; and DOE
NEPA guidelines (52 FR 47662-47670. December 1987). DOE and EG&G have prepared this IM/IRAP /EA to
identify and evaluate interim remedial action alternatives for contaminated surface water in the South Walnut
Creek drainage basin. Based on the evaluations, a preferred surface water collection and treatment system
is recommended.
DOE will implement this 1M/IRA while work progresses on the RCRA Facility
Investigation/CERCLA Remedial Investigation (RFI/RI) and RCRA Corrective Measures Study/CERCLA
FeasibUIty Study (CMS/FS) for OU 2.
Having presented the general extent of the contamination within the South Walnut Creek Basin and the
specific environmental issues associated with surface water contamination, this plan subsequently presents an
evaluation of the remedial alternatives with respect to effectiveness. implementability, and costs. Effectiveness
includes abUity to meet Applicable or Relevant and Appropriate Requirements (ARARs). It must be noted.
however. that in accordance with the National Contingency Plan (NCP) and the lAG. IM/IRAs need only attain
ARARs to the greatest extent practicable.
Surface water will be collected at one seep and at two in-stream locations on South Walnut Creek
upstream of the existing detention ponds. This will reduce the potential for further downstream contamination.
Screening of surface water treatment technologies includes evaluation of: suspended solids, radionuclides.
and metals removal by chemical treatment/cross-flow filtration. granular media filtration, and ion exchange. and
evaluation of volatile organic contaminant removal by granular activated carbon (GAC) adsorption. ultraviolet
peroxide oxidation, and air stripping with off-gas treatment. The chemical precipitation/cross-flow membrane
filtration system. together with a GAC adsorption system. is selected as the preferred alternative. Laboratory

and field treatability studies are being implemented in order to verify the performance of the selected
alternative. The current schedule for the field treatability studies calls for installation of a pilot system by Spring
1991. The field treatability unit will be operated to evaluate performance against chemical-specific ARARs. The
.
results may indicate that it is not practicable to attain all ARARs for the Surface Water 1M/IRA. Final
performance requirements for the 1M/IRA will require approval by the regulatory agencies. An additional
.,
function of the field treatability unit is the characterization and quantification of residuals generated by the
treatment processes being operated. thus allowing confirmation or modification of assumptions made in this
1M/IRA PI~n regarding the nature of treatment residuals. Table 0-1. Appendix D. shows the mUestone schedule
for the South Walnut Creek Basin Surface Water 1M/IRA project.
The IM/IRAP /EA examines the environmental and health risks associated with each of the alternatives,
including the preferred alternative. in accordance with the requirements of NEPA. The results of this evaluation
illustrate that the potential negative impacts to air and water quality, land. and short- and long-term land
productivity, as well as exposure of personnel. are minimal compared to the benefits of the resulting water
quality improvements to the surface waters of the area.

INTRODUCTION
.
Water quality investigations have identified the presence of volatile organic compound (VOC) and
...
radionuclide contamination of surface water at the Rocky Rats Plant (RFP).
The subject Interim
Measures/Interim Remedial Action Plan/Environmental Assessment QM/IRAP /EA) addresses contaminated
surface water in a portion of the South Walnut Creek drainage basin located within an area identified as
Operable Unit No.2 (OU 2). There is no immediate threat to public health and the environment posed by
surface water contamination because the affected surface water is contained within the plant boundary by
existing detection ponds, and is treated prior to discharge for removal of volatile organic contaminants and
suspended particulates to which radionuclides, if present, are likely to adsorb. However, there is a potential
threat and the Department of Energy (DOE) is implementing this Surface Water Interim Measures/Interim
Remedial Action (1M/IRA) at the request of U.S. Environmental Protection Agency (EPA) and Colorado
Department of Health (CDH). Implementation of the Surface Water 1M/IRA will enhance the DOE's efforts
towards containing and managing contaminated surface water, and will mitigate downgradient migration of
contaminants. Another factor in implementing this 1M/IRA is the length of time it will take to complete the
investigations and engineering studies necessary to determine the final remedy for OU 2.
In February and March 1990, representatives from DOE, EPA, and CDH met to discuss surface water
IM/IRAs at the RFP site. The result of these meetings was a series of agreements, with the general agreement
of all parties, to implement an 1M/IRA for the clean-up of contaminated surface water in the area designated
as OU 2. OU 2 is defined in the final Environmental Restoration Federal Facility Agreement and Consent Order
(FFACO) (DOE, 1991), commonly known as the Inter-Agency Agreement ~AG). and is comprised of several
Individual Hazardous Substance Sites (IHSSs) that were formeriy known in aggregate as the 903 Pad, Mound,
and East Trenches Areas.
On 26 September 1990, the DOE released for public comment a Surface Water 1M/IRA Plan and
Decision Document for OU 2. In this Plan, specific point source locations in the South Walnut Creek and

Woman Creek drainage basins were proposed for collection of surface water. According to the Plan, surface
water collected In each basin was to be transferred to a treatment facility discharging to the South Walnut
Creek drainage. Comments on the 1M/IRA Plan received during the public comment period. however, revealed
.
strong opposition to the transfer of radlonuclide contaminated seep water from the Woman Creek drainage
to the South Walnut Creek drainage.
~
Opposition was based on the absence of a proven performance record for the proposed 1M/IRA
treatmenUacDIty with respect to radionuclide removal and the potential for treatment process upsets. In
addition, the public voiced strong concern over potential worker and public health risks resulting from
construction activities In the Woman Creek Basin (Le., atmospheric suspension of radionuclide-contamlnated
dust). In light of these concerns, the DOE and regulatory agencies agreed to eliminate the proposed interbasin
transfer of surface water and to collect and treat Woman Creek seepage under a separate au 21M/IRA
project. It is expected that the Surface Water 1M/IRA Plan for Woman Creek Basin can be completed during
the summer of 1991. This will allow adequate time to conduct bench-scale treatability studies of radionuclide
removal treatment processes. The results of the bench-scale studies will provide a better assessment of
applicable treatment technologies in selection of the preferred 1M/IRA alternative for the Woman Creek Basin.
The Surface Water 1M/IRA dated 26 September 1990 has thus been modified to focus on collection and
treatment of South Walnut Creek Basin contaminated surface water. The Piar. oresented in this document
reflects this modification. In addition to previous consideration of collection of surface water at stations SW-59
- .-
and SW~1. this Plan also proposes collection at a third location designated as SW-132. SW-132 represents
the discharge of a buried, corrugated metal culvert approximately 225 feet downgradient of SW.Q1. Recent
field surveys and review of as-buit site drainage drawings have identified the culvert to be a conduit for flow
from the upper reach of South Walnut Creek within the Perimeter Security Zone (PSZ). Although water quality
data are not available at this newly designated station. Its character Is expected to be similar to the flow at
SW.Q1. A flow monitoring and sampling program has recently been Initiated at SW-132. This South Walnut
Creek Basin 1M/IRA Plan will provide for the collection of all flow from SW-59. SW.Q1, and SW-132 except
during infrequent high flow periods resulting from high precipitation events.

This 1M/IRA will be conducted in accordance with the Resource Conservation and Recovery Act of 1976
.
(RCRA) as amended by the Hazardous and Solid Waste Amendments of 1984 (HSWA), the Comprehensive
Environmental Response, Compensation, and Uability Act of 1980 (CERCLA) as amended by the Superfund
Amendments and Reauthorization Act of 1986 (SARA), the National Environmental Policy Act (NEPA) of 1969.
..
DOE and EG&G have prepared this 1M/IRA Plan to identify and evaluate interim remedial action alternatives
for contaminated surface water in the South Walnut Creek drainage basin. Based on the evaluations. a
preferred 1M/IRA for the contaminated surface water is recommended.
This 1M/IRA Plan has been prepared to conform with the requirements for an Engineering
Evaluation/Cost Analysis (EE/CA) as defined in the National Contingency Pian (NCP) (FR Vol. 55, No. 46.
8813; 40 CFR 3OO.415[b][4]). It also conforms to the NEPA of 1969. as implemented by regulations
promulgated by the President's CouncU on Environmental Ouallty (CEO) (40 CFR 1500-1508). and DOE
Guidelines (52 FR 47622-47670. December 15, 1987).
This finalized IM/IRAP document is also an EA. Although the 26 September 1990 proposed IM/IRAP
contained all the information and assessments to make it an EA, It had not been approved as an EA by DOE
Headquarters and therefore coUd not be labeled as an EA. However. in the Executive Summary of the
26 September 1990 proposed IM/iRAP, It was noted that once public comment was received and DOE
Headquarters approved the NEPA aspects of the document. it would become an integrated CERCLA/RCRA .
NEPA document QM/IRAP /EA).

BACKGROUND
In March 1987. a Phase I Remedial Investigation (RI) under the Environmental Restoration (ER) Program
(formerty known as the Comprehensive Environmental Assessment and Response Program (CEARP)] began

OU 2 during 1987, and a draft RI report was submitted to EPA and CDH on December 31, 1987 (Rockwell
International, 1987a). Phase I data did not allow adequate definition of the nature and extent of contamination
.
for the purpose of conducting a feasibility study of remedial alternatives pertaining to contaminated media.
A draft Phase /I RI Sampling Plan that presents the details and rationale for further field work to achieve this
objective was submitted to the regulatory agencies in June 1988 (Rockwell International, 1988a). This draft
sampling plan was subsequentty revised and submitted as a final Phase II RCRA Facility Investigation/Remedial
..
Investigation Feasibility Study (RFI/RIFS) sampling plan in April 1990 (EG&G, 1990a). The plan was approved
by EPA in. May 1990.
A draft 1M/IRA plan for contaminated ground water at OU 2 was submitted in December 1989 (Rockwell
International, 19898). The plan was prepared based on limited knowtedge of the nature and extent of ground-
water contamination. Regulatory agency review of the document determined that, although an 1M/IRA for
ground water is required by the 1989 Agreement In Principle between DOE and CDH, insufficient information
on the nature and extent of ground-water contamination exists at this time to pursue effective ground-water
remediation. In order to facilitate early evaluation of the need for an 1M/IRA for ground water at OU 2, the final
Phase /I RR/RIFS sampling plan incorporates a phased investigation approach. The plan was approved by
the regulatory agencies. The phased approach is to investigate alluvial and hydraulically connected bedrock
migration pathways first, and then to subsequently investigate ground-water contaminant sources. This will
allow planning, design, and Implementation of a ground-water 1M/IRA, if necessary, before completion of the
RFI/RI and Corrective Measures Study/Feasibility Study (CMS/FS) for OU 2.

Section 3 identifies the objectives of the South Walnut Creek Surface Water 1M/IRA. Applicable or
Relevant and Appropriate Requirements (ARARs) and applicable environmental regulations. The objectives and
ARARs define the criteria used to identify and evaluate 1M/IRA alternatives.
Section 4 identifies technically feasible 1M/IRA alternatives for the collection and treatment of
contaminated South Walnut Creek Basin surface water. The 1M/IRA alternatives selected address the
objectives presented in Section 3. The alternatives are evaluated based on effectiveness. implementability, and
cost criteria.
Section 5 summarizes the analysis performed in Section 4, and Section 6 presents the preferred 1M/IRA.
Bench and field treatability studies to evaluate the performance of the preferred 1M/IRA are also discussed in
Section 6.
Sections 7 and e specifically address NEPA requirements regarding an analysis of environmental
impacts associated with the preferred 1M/IRA and other 1M/IRA alternatives. respectively. This analysis Is
intended to provide sufficient Information to aid In a NEPA determination of environmental impacts of the
proposed 1M/IRA. The SCOpe of the analysis does not include evaluation of the existing operations at the RFP,
final remedial actions at OU 2 or subsequent remedial actions at other locations of the RFP. The environmental
impacts of plant operation were previously analyzed in the final Environmental Impact Statement (EIS) (DOE,
1980). NEPA documentation for final remedial actions at OU 2 and any other RFP remedial actions will be
provided in future documents.

2.1 SITE DESCRIPTION AND BACKGROUND
--
2.1.1 Location and Facilitv Tvoe
The RFP is located in northem Jefferson County, Colorado. approximately 16 miles northwest of
downtown Denver (Figure 2-1). The plant site consists of approximately 6.550 acres of federally-owned land
in Sections 1 through 4, and 9 through 15, of T2S. R70W, 6th principal meridian. Plant buildings are located
within an area of approximately 400 acres, known as the RFP security area. The security area is surrounded
by a buffer zone of approximately 6.150 acres.
The RFP is a govemment-owned. contractor-operated (GOCO) facility. It is part of a nationwide nuclear
weapons research, development. production and plutonium reprocessing complex administered by the Rocky
Flats Operations Office of the DOE. The operating contractor for the RFP is EG&G Rocky Flats, Inc. The
facility manufactures components for nuclear weapons and conducts plutonium reprocessing and has been
in operation since 1951. The RFP fabricates components from plutonium, uranium, beryllium, and stainless
steel. Historically, production activities have included metal fabrication. machining. and assembly. 80th
radioactive and nonradioactive wastes are generated in the process. Current waste handling practices involve
on-site and off.site recycling of hazardous materials and off-site disposal of solid radioactive materials at
another DOE facility.
The RFP is currently an interim status RCRA hazardous waste treatment/storage facility. In the past,
both storage and disposal of hazardous and radioactive wastes occurred at on-site locations. Preliminary
assessments conducted under Phase 1 of the Environmental Restoration (ER) Program identified some of the
past on-site storage and disposal locations as potential sources of environmental contamination.

2.1 .2 acerable Unit 2 Descriction
\
au 2 is comprtsed of the 903 Pad and Up, Mound, and East Trenches Areas which are located east-
southeast of the RFP as shown In Figure 2.2. The Areas of au 2 lie within either the South Walnut Creek or
..
Woman Creek drainage basins. Although this 1M/IRA Plan exclusively addresses the collection and treatment
of contaminated South Walnut Creek Basin surface water, it is useful to examine the historical uses and
characteristics of all au 2 Areas. including the 903 Pad and Up Area which lies entirely within the Woman
Creek drainage basin.
Twenty sites. designated as IHSSs, lie within au 2: five in the 903 Pad Area. four in the Mound Area,
and 11 in the East Trenches Areas. The historical use of the au 2 IHSSs is discussed below.
2.1.2.1 903 Pad Area
F"lVe sites are located within the 903 Pad Area (Figure 2-2). These sites are:
903 Drum Storage Site (IHSS Ref. No. 112)
903 Up Site (IHSS Ref. No. 155)
Trench T~2 Site (IHSS Ref. No. 109)
Reactive Metal Destruction Site (IHSS Ref. No. 140)
Gas Detoxification Site (IHSS Ref. No. 183)
Presented below are brief descriptions of each. of these sites.
1.
903 Drum Storage Site (IHSS Ref. No. 112) - The site was used from 1958 to 1967 to store drums
containing radioactively contaminated. used machine cutting oil. The drums, some of which corroded
and leaked. contained oDs and solvents contaminated with plutonium or uranium. Most of the drums
contained lathe coolant consisting of mineral oil and carbon tetrachloride (CCI.) in varying proportions.
However. an unknown number of drums contained hydraulic oils. vacuum pump oils, trichloroethene
(TCE) , tetrachloroethene (PCE), silicone oils, and acetone (Rockwell International. 1987b).
Ethanolamine was also added to new drums after 1959 to reduce the drum corrosion rate. All drums
were removed by 1968.

After the drums were removed, efforts were made to scrape and move the plutonium-contaminated soil
into a relatively small area. cover it with fill material, and top it with an asphalt containment cover. This
remedial action was completed in November 1969. An estimated 5,000 gallons of liquid leaked into the
soil during use of the drum storage site. The liquid was estimated to contain 86 grams of plutonium
(Rockwellintem&tional, 1987b).
2.
903 Up Site (IHSS Ref. No. 155) - During drum removal and clean-up activities associated with the
903 Drum Storage Site, winds distributed plutonium beyond the pad to the south and east. Although
some plutonium-contaminated soils were removed, radioactive contamination is stHI present at the 903
Up Site in the surficial soils.
3.
Trench T-2 Site (IHSS Ref. No. 109) - This trench was used prior to 1968 for the disposal of sanitary
sewage sludge and flattened drums contaminated with uranium and plutonium.
4.
Reactive Metal Destruction Site (IHSS Ref. No. 140) - This site was used during the 1950s and 1960s
primarily for the destruction of lithium metal (DOE, 1986). Small quantities of other reactive metals
(sodium, calcium, and magnesium) and some solvents were also destroyed at this location (lIIsley,
1978).
5.
Gas Detoxification Site (lHSS 183) - Building 952, located south of the 903 Drum Storage Site, was
used to detoxify various bottled gases between June 1982 and August 1983.
A Phase I RI has been completed for these five sites. Phase II is planned for this fall.
2.1.2.2 Mound Area
The Mound Area is composed of four sites (Figure 2-2). These are:
Mound Site (IHSS Ref. No. 113)
Trench T-1 Site (IHSS Ref. No. 108)
01 Bum Pit NO.2 Site (IHSS Ref. No. 153)
Pallet Bum Site (IHSS Ref. No. 154)
These sites are described individually below.
1.
Mound Site (lHSS Ref. No. 113) - The Mound Site contained approximately 1,405 drums containing
primarily depleted uranium and plutonium contaminated lathe coolant. Some drums also contained
"Perclene" (Smith. 1975). Perclene was a brand name of tetrachloroethene (Sax and Lewis. 1987).
Some of the drummed wastes placed in the Mound Site were in solid form (Rockwellintemational.
1987b). Qeanup of the Mound Site was accomplished in 1970, and the materials removed were
packaged and shipped to an off.slte DOE facility as radioactive waste. Subsequent surficial soils
sampling in the vicinity of the excavated Mound Site indicated 0.8 to 112.5 disintegrations per minute
per gram (d/m/g) alpha activity. This radioactive contamination is thought to have come from the 903
Drum Storage Site via wind dispersion rather than from the Mound Site (Rockwellintemational, 1 987a).

2.
Trench T-1 Site (IHSS Ref. No. 108) - The trench was used from 1954 untU 1962 and contains
approximately 125 drums filled with depleted uranium chips (Dow Chemical, 1971) and plutonium chips
coated with lathe coolant. The drums are still present in this trench.
.:
3.
OU Sum Pit No.2 Site OHSS Ref. No. 153) - OU Sum Pit No.2 is actually two parallel trenches which
were used in 1957 and from 1961 to 1965 to bum 1,082 drums of oil containing uranium (Rockwell
International. 1987b). The residues from the buming operations and some flattened drums were
covered with backfill. Clean-up operations were performed in the 1970s (Rockwell International, 1987b).
.
4.
Pallet Sum Site (IHSS Ref. No. 154) - An area southwest of on .Sum Pit No.2 was reportedly used to
destroy wooden pallets in 1965. The types of hazardous substances or radionuclldes that may have
bee"n spilled on these pallets is unknown. Clean-up actions were performed in the 1970s (DOE, 1986).
2.1.2.3 East Trenches Area
The East Trenches Area consists of nine burial trenches and two spray irrigation areas (Figure 2-2).
The trench numbers and their respective IHSS designations are:
Trench T -3 - IHSS Ref. No. 110
Trench T -4 - IHSS Ref. No. 111.1
Trench T -5 - IHSS Ref. No. 111.2
Trench T ~ - IHSS Ref. No. 111.3
Trench T-7 -IHSS Ref. No. 111.4
Trench T -8 - IHSS Ref. No. 111.5
Trench T -9 - IHSS Ref. No. 111.6
Trench T-10 -IHSS Ref. No. 111.7
Trench T -11 - IHSS Ref. No. 111.8
Trenches T -3. T-4, T-10. and T-11 are located north of the east access road. and trenches T-5 through
T -9 are located south of the east access road. The trenches were used from 1954 to 1968 for disposal of
depleted uranium. flattened depleted uranium and plutonium-contaminated drums, and sanitary sewage sludge.
The wastes have not been disturbed since their burial.

2.1.3 Surroundina Land Use and PODuiation Densitv
The RFP is located in a rural area (Figure 2-3). Approximately 50 percent of the area within ten miles
of the RFP is in Jeffersan County. The remainder is located in Boulder County (40 percent) and Adams
County (10 percent). According to the 1973 Colorado Land Use Map, 75 percent of this land was unused or
was used for agriculture. Since that time, portions of this land have been converted to housing, with several
new housing subdivisions being started within a few mUes of the buffer zone, southeast of the plant site.
A demographic study, using 1990 census data, shows that approximately 1.9 million people lived within
the eight-county Denver metropolitan region. This region covers approximately 5.076 square miles and
includes the following counties: Adams. Arapahoe. Boulder, Denver, Douglas, Jefferson, Clear Creek, and
Gnpin. The most populated sector Is to the southeast, toward the center of Denver. This sector had a 1989
population of approximately 600,000 people living between 10 and 50 miles from Rocky Flats. Recent
population estimates registered by the Denver Regional Council of Governments (DR COG) for the eight-county
Denver metro region have shown distinct patterns of growth between the first and second halves of the
decade. Between 1980 and 1985. the population of the eight-county region increased by 197,890. a 2.4
percent annual growth rate (DRCOG, 1989). Between 1985 and 1990 a POPulation gain of 80.875 was
recorded, representing a 0.9 percent annual increase. The 1990 population showed an increase of 9.300 (or
0.5 percent) from the same date In 1989 (DRCOG. 1990).
The RFP is approximately located in the center of RFP legal land area which is approximately 3 miles
(north-south) by 4 miles (east-west). There are eight public schools within six miles of the RFP. The nearest

educational facUlty Is the WItt Elementary School, which is approximately 2.7 miles east of the Plant buffer zone.
The closest hospital Is Centennial Peaks Hospital, located approximately seven miles northeast. The closest
...
park and recreational area Is the Standley Lake area. which is approximately fIVe miles southeast of the Plant.
Boating, picnicking, and limited overnight camping are permitted. Several other small parks exist in
..
communities within ten mUes. The closest major park, Golden Gate Canyon State Park, located approximately
15 miles to the southwest, provides 8,400 acres of general camping and outdoor recreation. Other national
and state parks are located in the mountains west of the RFP. but all are more than 15 mles away.
Some of the land adjacent to the Plant is zoned for industrial development. Industrial facilities within
five mUes include the former TaSCa (The 01 Shale Company) laboratory (40-acre site located two mUes south
and now occupied by Analytica, Inc.), the Great Western Inorganics Plant (two mUes south), the Frontier Forest
Products yard (two mUes south), the Idealite Ughtweight Aggregate Plant (2.4 mUes northwest). and the
Jefferson County Airport and Industrial Park (99O-acre site located 4.8 mUes northeast).
Several ranches are located within ten mUes of the Plant, primarily in Jefferson and Boulder Counties.
They are operated to produce crops, raise beef cattle, supply mAk. and breed and train horses. According to
the 1987 Colorado Agricuttural Statistics, 20,758 acres of crops were planted in Jefferson County (total land
area of approximately 475,000 acres), and 68,760 acres of crops were planted in Boulder County (total land
area of 405,760 acres). Crops consisted of: winter wheat, com. baney, dry beans, sugar beets, hay. and oats.
livestock consisted of: 5,314 head of cattle, 113 hogs. and 346 sheep in Jefferson County, and 19,578 head
of cattle. 2,216 hogs, and 12,133 sheep In Boulder County (Post, 1989).
2.2
AFFECTED AND SENSmve ENVIRONMENT
2.2.1
Phvsical Environment
The natural environment of the Plant and vicinity is influenced primarily by Its proximity to the Front
Range of the Rocky Mountains. The Plant is directly east of the north-south trending Rocky Mountains, with

an elevation of approximately 6,000 feet above sea level. The RFP is located on a broad. eastward-sloping
plain of overtapping alluvial fans developed along the Front Range. The fans extend about fIVe miles in an
..
eastward direction from their origin in the abruptly rising Front Range and terminate on the east at a break in
slope to low roiling hDls. The continental divide Is about 16 mUes west of the Plant. The operational area at
the Plant is located near the eastem edge of the fans on a terrace between stream-cut valleys (North Walnut
.
Creek and Woman Creek). The Rocky Fiats Alluvium (the deposit of coalescing alluvial fans) Is exposed at the
surface and consists of a topsoil layer undertain by as much as 100 feet of silt. clay, sand. and gravel.
The RFP Is situated In a semiarid region that averages 15 inches of annual precipitation. Forty percent
of the yearty total comes in the spring, much of It in the form of snow. Of the balance. 30 percent is accounted
for by summer thunderstorms, with the rest occurring in the fall (11 percent) and winter months (19 percent).
Average yearty snowfall is 85 inches. Runoff control structures exist to channel surface water from the Plant
to monitoring ponds. These structures are sized to accommodate the 100-year storm event which is equivalent
to four inches of rain in a six-hour period.
Mineral resources found In the vicinity of RFP include sand, gravel. crushed rock. clay, coal. and
uranium. There are no known clay, coal or uranium deposits within the RFP buffer zone; however. these
commodities are mined in the region, within 20 mDes of the plant. The Schwartzwaider Uranium Mine is
located approximately four mDes southwest of the RFP. The mine has been the largest producer of vein type
uranium ore In Colorado and ranks among the six largest of this type In the United States (DOE. 1980). Active
sand and gravel mines lie within the buffer zone boundaries. There Is an aggregate processing facility adjacent
to the northwest comer of the buffer zone which reopened in 1989. 00 and natural gas production is also
active in nearby northwest Adams County and east central Boulder County.
Oil and natural gas activity near Rocky Fiats Plant includes oilfield developments. pipeline. and
production operations. The closest major oil and gas fields are in northwest Adams County (Jackpot and
Spindle Fields), and a smaller field occurs in east central Boulder County (Boulder Field). A natural gas
pipeline that originates in Wyoming and proceeds across eastem Colorado into Oklahoma is located

approximately ten mUes north of the Plant in southern Boulder County. Local natural gas pipelines cross the
south side of the Rocky Flats Plant. The nearest refinery operation is the Conoco Refinery located in
...
Commerce City about 20 mUes east of the Plant. A north-south oriented oil pipeline feeds in to the refinery
from fields in northeastern Colorado and southeastern Wyoming (Donaldson and MacMillan, 1980).
.
There are four main drainages from the Plant property as shown on Figure 2~. North Walnut. South
Walnut, Rock and Woman Creeks all have intermittent streams which provide drinking water and irrigation
water. T~ere are a number of ditches crossing the area as well. conveying water collected off site to other
areas, the Plant, Walnut Creek, or Woman Creek. UntO late 1974, Plant wastewater had been discharged to
Walnut Creek, and untU 1975, filter backwash from the raw water treatment plant went into Woman Creek.
All process wastewater is now either recycled or disposed through evaporation. Sanitary wastewater is
discharged In accordance with the RFP's NPDES permit effluent requirements.
2.2.2 Reaional and Local Hvdroaeoloav
The stratigraphic section that pertains to the RFP includes. in descending order, unconsolidated surficial
units (Rocky Flats Alluvium, various terrace alluviums, valley fill allUvium, and colluvium) (Figure 2-5), Arapahoe
Formation, laramie Formation, and Fox Hills Sandstone (Figure 2~). Ground water occurs under unconfined
conditions In both the surficial and shallow bedrock units. In addition, confined ground-water flow occurs in
deeper bedrock sandstones.
2.2.2.1 Alluvial Materials
The Rocky Flats Alluvium underlies a large portion of the Plant. The alluvium is a broad planar deposit
consisting of a topsoU layer underlain by up to 100 feet of peony stratified silt. clay. sand, gravel and cobbles.
Unconfined ground-water flow occurs in the Rocky Flats Alluvium which is relatively permeable. Recharge to
the alluvium is from precipitation, snowmelt, and water losses from ditches, streams. and ponds that are cut
into the alluvium. General water movement in the Rocky Flats Alluvium is from west to east and toward the

drainages. Ground-water flow is also controlled by sediment drainages in the top of bedrock. The water table
in the Rocky Flats Alluvium rises in response to recharge during the spring and declines during the remainder
\.
of the year. Discharge from the alluvium occurs at minor seeps in the colluvium that covers the contact
between the alluvium and bedrock along the edges of the valleys. au 2 Is situated on a terrace of Rocky Flats
,.
Alluvium that thins east of the Plant and does not directly supply water tQ wells located downgradient of Rocky
Flats.
Various other alluvial deposits occur topographically below the Rocky Flats Alluvium In the Plant
drainages. Colluvium (slope wash) mantles the valley side slopes between the Rocky Flats Alluvium and the.
valley bottoms. In addition, remnants of younger terrace deposits including the Verdes. Slocum. and Louviers
Alluvia occur occasionally along the valley side slopes. Recent valley fill alluvium occurs in the active stream
channels.
Unconfined ground-waterflow occurs in these surficial units. Recharge is from precipitation, percolation
from streams and ditches during periods of surface water runoff, and by seeps discharging from the Rocky
Flats Alluvium. Discharge is by evapotranspiration and by seepage into other geologic formations and streams.
The direction of ground-water flow is generally downslope through colluvial materials and then along the course
of the stream in valley fill materials. During periods of high surface water flow, water is lost to bank storage
in the valley fill alluvium and returns to the stream after the runoff subsides.
2.2.2.2 Bedrock Matertiils
The Cretaceous Arapahoe Formation underlies surficial materials beneath the Plant. This formation is
a fluvial deposit composed of overbank and channel deposits. It consists primarily of claystone with some
sandstone and is near1y flat lying beneath the Plant Oess than a two-degree dip) based on the draft seismic
profiling report (Rockwell International. 19898). The sand bodies within the claystone are composed of fine-
grained sands and silts, and their hydraulic conductivity is relatively low compared to the over1ying Rocky Flats

Alluvium. A high resolution seismic reflection survey is ongoing at the Plant to further characterize bedrock
geology.
J
The Arapahoe Formation is recharged by ground-water movements from overiying surficial deposits
and by leakage from streams. The main recharge areas are under the Rocky Aats Alluvium, although some
.
recharge from the colluvium and valley fill alluvium likely occurs along the stream valleys. Recharge is greatest
during the spring and ear1y summer when rainfall and stream flow are at a maximum and water levels In the
Rocky Flats Alluvium are high. Ground-water movement in the Arapahoe Formation Is generally toward the
east, although flow within Individual sandstones Is not fully characterized at this time. Regionally, ground-water
flow In the Arapahoe Formation is toward the South Platte River in the center of the Denver Basin (Robson,
1981a).
The Laramie formation under1ies the Arapahoe and is composed of two units, a thick upper claystone
and a lower sandstone. The claystone is greater than 700 feet thick and Is of very low hydraulic conductivity;
therefore, the U.S. Geologic Survey (Hurr, 1976) concludes that Plant operations WIll not impact any units
below the upper claystone unit of the Laramie Formation.
The lower sandstone unit of the Laramie Formation and the under1ying Fox Hills Sandstone comprise
a regionally important aquifer in the Denver Basin known as the Laramie-Fox Hills Aquifer. Aquifer thickness
ranges from 200 to 300 feet near the center of the basin. These units subcrop west of the Plant and can be
seen In clay Pits excavated through the Rocky Flats Alluvium. The steeply dipping beds of these units west
of the Plant (a~mately a SO-degree dip) qulcldy flatten to the east ~ess than two-degree dip) based on
preliminary resutts of the high resolution seismic reflection study (Rockwellintemational, 1989a). Recharge
to the aquifer occurs along the rather limited outcrop area exposed to surface water flow and leakage along
the Front Range (Robson, 1981b).
Sixteen wells were completed in various zones within bedrock during the 1987 drilling program at au 2.
Although claystone was the most frequently encountered lithology immediately below the alluvium/bedrock

2.2.3.1 Surface Water
Surface water drainage patterns at the RFP are shown on Figures 2-2 and 2-4. A discussion of the
major au 2 surface water features. including the South Walnut Creek and Woman Creek drainages, is
presented below. Although this 1M/IRA Plan addresses collection and treatment of contaminated South Walnut
Creek Basin surface water; the Woman Creek drainage is included in the following discussion to provide a
complete description of au 2 hydrology. Collection and treatment of Woman Creek Basin seepage southeast
of the 903 Pad Area wUl be addressed In a separate 1M/IRA Plan as discussed in Section 1.
South Walnut Creek
The headwaters area of South Walnut Creek has been filled during construction of RFP facilities. As
a result. flow originates from a buried culvert located west of Building 991. Flow in the upper reach of South
Walnut Creek Is directed to the south d Building 991 and under the Perimeter Security Zone (PSZ) fence by
a buried met8J corrugated cUv8rt. The culvert outlet Is located in the South Walnut. Creek drainage
approximately 500 feet downgradlent of the PSZ fence near the discharge of the sewage treatment plant (see
Figure 4-2). A concrete cutvert and a second metal corrugated culvert also discharge into the South Walnut
Creek drainage just downgradient of the PSZ fence and north of the Mound Area. The flow from the concrete
culvert originates as seepage from the hOlside south of Building 991 and flows into a ditch along the slope.
The metal corrugated culvert drains plant runoff collecting in a drainage south of the PSz. The combined flow
then enters the South Walnut Creek detention pond system. Below the detention ponds, South Walnut Creek,
North Walnut Creek, and an unnamed tributary join within the buffer zone to form Walnut Creek. Great Western

Reservoir is located approximately one mile east of this confluence and is a drinking water source for
Broomfield. Flow is routed around Great Westem Reservoir by the Broomfield diversion canal.
.~
The South Walnut Creek detention pond system consists of five ponds (B-1, B-2. B-3. B-4, and B-5) that
retain surface water runoff and RFP discharges for flood control. and for monitoring and treatment prior to
"
downstream release. All flow in the pond system is eventually detained in Pond B-5, where it is treated and
monitored prior to discharge. Water is discharged from Pond B-5 in accordance with the Plant's NPDES permit
(discharge point 006). Ponds B-1 and B-2 are reserved for spUi control, surface water runoff, or treated
sanitary waste of questionable quality. Pond B-3 is used as a holding pond for sanitary sewage treatment plant
effluent. The historical discharge of Pond B-3 was a spray irrigation system located in the vicinity of the East
Trenches. This practice has been terminated, however, and the current Pond B-3 discharge is sent to Pond
B-4. In addition to Pond B-3 discharge, Ponds B-4 and B-5 receive surface water runoff from the central
portion of the Plant. The surface water runoff received by Pond B-4 is collected by the Central Avenue Ditch
and the South Walnut Creek Drainage.
Woman Creek
Woman Creek Is located south of the Plant, with headwaters in largely undisturbed Rocky Flats
Alluvium. Runoff from the southern part of the Plant is collected in the South Interceptor Ditch located north
of the creek and delivered downstream to Pond 0.2 (see Figure 2-2). Pond C-1 (upstream of 0.2) receives
stream flow from Woman Creek. Flow In Woman Creek is also influenced by diversion 01 water from Rocky
Rats Lake Into the creek by local landowners. The discharge from Pond 0.1 is diverted around Pond C-2 into
the Woman Creek channel downstream. Water in Pond 0.2 is treated and monitored prior to discharge.
Discharge from Pond 0.2 is In accordance with the Plant's NPDES permit (discharge point 007). Historically,
discharge from Pond 0.2 has been to Woman Creek, however, since October of 1989. treated water is being
pumped to the South Walnut Creek drainage and flows off site via the Broomfield diversion canal.

2.2.3.2 Ground Water
Ground water occurs in surficial materials (Rocky Flats Alluvium, colluvium, and valley fill alluvium) and
in Arapahoe sandstones and claystones at OU 2. These two flow systems. which are hydraulically connected
at shallower portions of the Arapahoe Formation, are discussed separately below.
Ground Water in Surficial Materials
Ground water is present In the Rocky Flats Alluvium, colluvium, and valley fill alluvium under unconfined
conditions. Recharge to the water table occurs as infiltration of incident precipitation and as seepage from
ditches and creeks. In addition, detention ponds along South Walnut Creek and Woman Creek recharge the
valley fli alluvium. Figure 2-7 shows the potentiometric surface of uppermost ground water measured between
April 4 and April 8, 1988, and the locations of alluvial and bedrock wells in the vicinity of OU 2.
The shallow ground-water flow system is quite dynamic, with large water level changes occurring in
response to precipitation events and stream and ditch flow. For example, between mid-April and September,
1986, water leVels In wells 1-86 and 4-86 (completed in valley fill alluvium) dropped more than four and eight
feet, respectively. Alluvial water levels are highest during the months of May and June. Water levels decline
during late summer and fall, and some wells go completely dry at this time of year. Ground-water flow in the
Rocky Flats Alluvium is generally from west to east, following the surface of the claystone bedrock.
Alluvial ground water discharges to seeps, springs. surface water drainages, and subcropping Arapahoe
Sandstone at OU 2. Seeps and springs occur along the edge of the Rocky Flats Alluvium terrace (at the
alluvium/bedrock contact) and on the side slopes of the terrace. Seeps and springs on the terrace side slopes

Hydraulic conductivity values were estimated for surficial materials from drawdown-recovery tests
performed on 1986 wells during the initial site characterization and from slug tests performed on selected 1986
and 1987 wells during the Phase I RI (Rockwell I ntemational , 1987a). The average ground-water velocities in
the Rock)L Flats Alluvium, Woman Creek Valley FUI Alluvium, and South Walnut Creek Valley FUI Alluvium are
84 ft/yr, 145 ft/yr, and 20 ft/yr, respectively (Rockwell I ntemational , 1987a). These values are based on a
horizontal gradient of 0.02 feet/feet (ft/ft), an effective porosity of 0.1, and mean hydraulic conductivities of 4 x
10", 7 x 10" and 9.5 x 1006 cm/s for Rocky Flats, Woman Creek Valley FBI and South Walnut Creek Valley Fill
Alluvium. respectively. The calculations assume year-round saturation. However, as discussed above, portions
of the Rocky Flats Alluvium, colluvium, and valley fill alluvium are not continuously saturated. Thus, the shallow
ground water must flow at less than the calculated annual average velocities. The reactivity of dissolved
constituents could further reduce contaminant migration rates below estimated ground-water velocities.
Bedrock Ground Water
The greatest potential for ground-water flow in the Arapahoe Formation occurs in the meandering
lenticular sandstones contained within the claystones (Le., the basal formation) due to their relatively higher
permeability. Flow within individual sandstones is assumed to be from west to east, but the geometry of the
bedrock ground-water flow path is not fully understood at this time due to its dependence upon the continuity
of the sandstones and their hydraulic interconnection (Robson, 1981 a). Ground-water recharged to sandstones
occurs as infiltration from alluvial ground water where sandstones sUbcrop beneath the alluvium and by leakage
from claystones overlying the sandstones. Ground-water from the basal formation of the Arapahoe aquifer is
used for irrigation, livestock, watering, and domestic purposes. Wells are located east of the RFP within the
Denver Basin.

There is a strong downward gradient between ground water in surficial materials and bedrock. Vertical
gradients range from 0.31 ft/ft between wells 35-86 and 34-86 to 1.05 ft/ft between wells 41-86 and 40-86.
j
These gradients imply a relatively high hydraulic conductivity contrast between the surficial materials and
bedrock, which is supported by hydraulic conductivity test results.
.
Flow within sandstones is regionally west to east. The geometry of the ground-water flow path in the
bedrock is not fully understood at this time because it depends upon the continuity of the sandstones and their
interconn~ion. Evaluation of the lateral extent and degree of interconnection of the sandstone units is a
primary goal of the Phase II and Phase III Remedial Investigations for OU 2.
Hydraulic conductivity values for Arapahoe sandstones were estimated from drawdown-recovery tests
performed In 1986. slug tests performed in 1987, and packer tests performed In 1986 and 1987. The maximum
horizontal ground-water flow velocity in sandstone is 75 ft/yr using a hydraulic conductivity of 83 ftjyr, a
horizontal gradient of 0.09 ft/ft. and an assumed effective porosity of 0.1.
2.2.4 Ecoioav
Within the Plant boundaries a variety of vegetation thrives. Included are species of flora representative
of tall grass prairie. short grass plains. lower montane. and foothill ravine regions, with none being on the
endangered species list. It is evident that the vegetative cover afong the Front Range of the Rocky Mountains
has been radically altered by human activities such as burning, timber cutting. road building, and overgrazing
for many years. Since the acquisition of the RFP property, vegetative recovery has occurred as evidenced by
the presence of grasses like big bfuestem and sideoats grama (two disturbance-sensitive species). No
vegetative stresses attributabfe to hazardous waste contamination have been identified (DOE, 1980).
The animal life inhabiting the RFP and its buffer zone consists of species associated with western prairie
regions. The most common large mammal is the mule deer, with an estimated 100 to 125 permanent
residents. There are a number of small carnivores. such as the coyote, red fox. striped skunk, and long-tailed

weasel. A profusion of small herbivore species can be found throughout the Plant and buffer zone consisting
"
of species such as the pocket gopher, white-taRed jackrabbit, and the meadow vole (DOE. 1980).
Commonly observed birds Include western meadowtarks. horned larks, mourning doves. and vesper
.
sparrow. A variety of ducks. killdeer, and red-winged blackbirds are seen In areas adjacent to ponds. Mallards
and other ducks frequently nest and raise young on several of the ponds. Common birds of prey in the area
include marsh hawks, red-tailed hawks. ferruginous hawks. rough-legged hawks. and great horned owls (DOE.
1980). .
Bull snakes and rattlesnakes are the most frequently observed reptDes. Eastern yellow-bellied racers
have also been seen. The eastern short-homed lizard has been reported on the site. but these and other
lizards are not commonly observed. The western painted turtle and the western plains garter snake are found
in and around many of the ponds (DOE. 1980).
2.2.5
Sensitive Environments and Endanaered SDeCies
The Endangered Species Act of 1913 (Public Law 93~205). as amended. provides that all federal
agencies implement programs for the conservation of listed endangered and threatened species. Federal
agencies must ensure that actions authorized, funded. or carried out by them will not jeopardize the continued
existence of any endangered or threatened species.
The U. S. Fish and WIldlife Service (USFWS) has indicated that the two endangered species of interest
in the RFP area are the bald eagle and the black-footed ferret (Rockwellintemational. 1988c). Prairie dog
towns provide the food source and habitat for ferrets. Since there are no prairie dog towns in or near the 881
Hillside Area which Is near the 903 Pad. Mound and East Trenches, the USFWS has determined that ferrets
probably do not exist in the investigation area. Bald eagles are occasional visitors to the area. primarily during
migration times. Sightings are rare and little suitable habitat exists on the RFP site other than some perching
locations. No nests are found on the RFP site. The proposed action will not adversely affect the bald eagle.

The USFWS has concurred with these findings subsequent to a field visit on 15 June 1988 (Rockwell
International, 1988c).
J
Other animal species of interest that exist in the RFP area include burrowing owls and Swainson's
hawks. Cottonwood trees within approximately one quarter mile of the 903 Pad, Mound, and East Trenches
6.
Areas were investigated to determine if any raptor nests exist and none were found. The nearest population
of burrowing owls Is approximately two miles to the east. The nearest population of Swalnson's Hawks could
be in the cottonwood trees in the area of the North Walnut Creek or Rock Creek drainages, north of the 88 1
HUiside area.
The 903 Pad, Mound, and East Trenches Areas are not used, nor intended for use, as a public or
recreational area. nor for the development of any unique natural resource. No unique ecosystems were found
at the RFP during extensive biological studies (DOE, 1980).
2.2.6 Wettands
Initial consultation with the USFWS and the U.S. Army Corps of Engineers was conducted in the spring
of 1988. Wetlands at the RFP site were delineated. The proposed action is not located in the delineated
wetlands. Aerial photography imagery for the 903 Pad. Mound, and East Trenches Areas was examined for
wetlands identification followed by limited site inspection (EG&G, 1990b). Two isolated stands of wetlands
vegetation containing common cat-taU ~ latifolia) were located primarily within IHSS 140, where ground
water flowing toward the terrace edges emerges as seeps or springs at the contact between the alluvium and
bedrock. The two areas are each less than 20 square feet In size.
Unear wetlands areas have been identified along both the Woman Creek and South Interceptor Ditch
drainage areas. These drainages collect surface water upgradient from OU 2 and deliver the water to pond
Co2 for treatment. Evenly-spaced drop structures along the South Interceptor Ditch have lowered flow
velocities, increased sediment accumulation, and created fair1y dense linear stands of wetlands. From a point

due south of Building 881 and extending to the C-2 Pond. approximately 0.15 acres of wetland are contained
within this portion of the South Interceptor Ditch. Wedand species observed were primarily cattails (greater
-,
than 95 percent predominance), spike rush lEleocharis macrostachva) and bull rush (Scircus americanus). The
wedands function primarily as flow attenuation features with additional minor contributions to wildlife habitat
..
and water quality enhancement. Drainage contribution to the South Interceptor Ditch from OU 2 is minimal.
2.2.7 Historic Sites
The National Historic Preservation Act of 1966 (Public Law 89-665) together with subsequent law
amendments (Public Laws 91-243, 93-54. 94-422, 94-458) provides that all federal agencies implement
programs for the protection of archeological and historical resources.
The 903 Pad. Mound and East Trenches Areas have been highly disturbed over a number of years.
Due to this disturbance and the topographic position of the subject area, the State Office of Archeology and
Historic Preservation has determined that this action will not impact cultural resources (Burney, 1989). An
archaeological and historical survey of the RFP was conducted between July 18 and August 22. 1988. which
determined two sites have potential eligibDity to the National Register of Historic Places. However.
insufficient information currently exists to make this determination. These two sites are located northwest and
southwest of the investigation area and will not be disturbed by the proposed action (Burney, 1989).

CONTAMINANTS - DESCRIPTION AND SOURCES
2.3.1
Backaround Characterization
In order to facilitate the interpretation of chemical results in non-background areas. a background
characterization program has been implemented to define the spatial and temporal variabnlty of naturally
occurring constituents.
Fieldwork was conducted in 1989. and a draft Background Geochemical
Characterization Report was prepared and submitted to the regulatory agencies on December 15. 1989
SURFACE WATER INTERn.,. REMEOIAL ACT10N F'I.AN
I'!OCI
-------
(Rockwell International. 1989c). The document summarizes the background data for ground water, surface
water. sediments. and geologic materials. and identifies preliminary statistical boundaries of background
..
variabUIty. Spatial variations In the chemistry of geologic materials and water were addressed by placing
sample locations throughout background areas at the Plant. The goal of evaluating temporal variations in water
chemistry has not yet been achieved because at least two years of quarterty data are needed.
'II.
The draft report has been updated by incorporation of analytical data that were unavaDabie in December
1989. including additional rounds of ground-water and surface water samples for which laboratory analyses
were not avaUabie. The information in the draft background geochemical report has been used to preliminarily
characterize inorganic contamination at the 903 Pad. Mound. and East Trenches Areas. The draft report
presents tolerance intervals for surface water, sediment, and various soli lithologies and hydrogeologic units
(ground water); The tolerance intervals are statistical ranges of the background analyte concentrations in the
various media that represent 95 percent of the population with 95 percent confidence. Summary tables of the
upper limits of these tolerance intervals are provided in Tables A-1 through A~ (see Appendix A) for reference.
2.3.2 Ground-Water Contamination
Ground water at the RFP has been monitored since 1986. Wells have been installed throughout the
property and are sampled quarterty. The following discussion is based on the resulting data.
2.3.2.1 Volatne Organic Contamination
Table A-S (Appendix A) presents all volatile organic compounds (VOCs) with concentrations that are
above detection limits in the unconfined ground-water system during the second quarter of 1989. These are
the most recent validated data pertaining to the same season for which the background levels were
determined. Maximum concentrations of volatile organics based on the complete data set (1986-1989
sampling) are summarized in Table A~. The primary volatile organic ground-water contaminants (CCI.. PCE,

and TCE) are portrayed with isopleths in Figures 2-8 through 2-10 based on second quarter 1989 data for both
unconfined alluvial and bedrock wells.

Aluminum. antimony. arsenic. barium. cadmium. chromium, copper, iron. lead, lithium, manganese.
mercury, molybdenum. nickel. potassium. selenium, silver, strontium, vanadium and zinc exceeded background
..
in one or more wells in the second quarter of 1989. Table A-8 (Appendix A), a summary of multiple sampling
events (up to fourteen samples collected from each well during 1987-1989). shows that only a subset of these
analytes repeatedly exceed background (upper limit of the tolerance interval) and/or exceed background by
a wide margin. The sporadic exceedances of background. and the absence of apparent gradients in metal
concentrations with respect to IHSSs. hinders drawing definite conclusions as to whether these constituents
are derived from IHSSs (EG&G. 1990a). Section 2.3.5 makes reference to this and other ambiguities in the
ground-water chemistry data to the extent that they may be relevant to the Surface Water 1M/IRA Plan.
Radionuclides
Table A-9 (Appendix A) shows that dissolved concentrations of the uranium isotopes (U-234, U-235,
and U-238). plutonium, and americium have been above background at OU 2. The maximum concentration
for uranium 238 was 28 % 2 pCl! t in well 12-87 in the 903 Pad Area. Numerous occurrences of uranium at
lower concentrations and in wells completed in diverse lithologies demonstrate that the distribution of uranium
is not thoroughly delineated at OU 2. With respect to plutonium and americium. results at wells 15-87 and 1 1 .
87 were the most elevated (plutonium 0.522 % .117 pCij t and 0.199 % 0.07 pCij t. respectively: americium
0.831 % 0.148 pCitl and 0.06 % .05 pCijl. respectively).
2.3.3
Soil Contamination
The extent of soil contamination at the 903 Pad. Mound. and East Trenches Areas was determined from
soil samples collected in 1987 during the Phase I RI. Samples were collected from boreholes drilled in and
adjacent to known IHSS locations (Figure 2-11). Two-foot intervals were composited for organic analyses. and
two- to ten-foot intervals were composited for all other analytes. Boreholes were not drilled into sites still

containing wastes (the trenches and 903 Pad) due to potential health hazards to field workers and potential
for release of waste constituents to the environment. The soils data are summarized here because of the
...
potential influences contaminated soils may have on surface water quality. Either direct contribUtions via
overtand runoff, or direct influences via ground-water interactions are possible. The discussion is considered
.
preliminary because wastes were not directly sampled and soils data are still being evaluated.
VOCs. including PCE, TCE, toluene, 2-butanone, CCI.. acetone and methylene chloride, were reported
in samples from the 903 Pad and East Trenches Areas (see Table A-10). Occurrences of total xylenes,
ethyl benzene and toluene were also reported for the 903 Pad Area, whereas 1-2-dichloroethane (1.2-DCA),
1,1,1-TCA. and 1,1.2-TCA were reported in an East Trenches borehole. The Mound Area, like other portions
of au 2, contained acetone (hundreds of pg/1) and methylene chloride (typically tens of J.lgi I) at
concentrations too low to unambiguously demonstrate contamination with these compounds. Other organic
constituents in the Mound Area (PCE. CHCl3. 1,2-DCA) were less numerous and at lower levels than at other
areas within OU 2. Semi-volatile organic compounds di-n-Butyl phthalate, bis(2-Ethylhexyl) phthalate, and N-
nitrosodiphenylamine were detected in numerous boreholes throughout au 2 (see Table A-11, Appendix A).
Several metals occurred above background in soil samples (aluminum, arsenic. barium, cadmium,
calcium, iron. mercury, manganese. lead, antimony, vanadium and zinc). although most exceeded background
by less than a factor of two and/or in only one or two samples. Table A-12 (Appendix A) presents maximum
metal concentrations in soils.
Plutonium a~ americium are the principal radionuclide contaminants exhibiting elevated concentrations
in soils. Table A-13 (Appendix A) presents maximum radionuclid~ concentrations in soils at au 2. Highest
concentrations occurred in samples that included the surface. Because many of the surface soil samples were
mixed into large composites, the Phase I RI data do not rule oUt the presence of radionuclides other than
plutonium and americium. Cesium-137, tritium, and uranium were detected, albeit at near-background
concentrations and in fewer than ten samples. Surface contamination of soils with plUtonium and americium
was further demonstrated by a recent aerial radiological survey (EG&G, 1989). The radioactivity detected in

that survey was associated with known radioactive material storage and handling areas (Le., the 903 Pad), and
was attributed to plutonium. americium, and a uranium decay product. The survey indicated elevated
IT
concentrations of americium in soils east of the 903 Pad Up Site as high as 97 pCijg, and by inference from
their expected activity ratio, plutonium as high as 500 pCijg. Subsequent analysis of samples from the area
..
with high americium concentrations indicated plutonium concentrations as high as 457 pCi/g. The cesium-137
activity was at a level consistent with global fallout and not enriched in the Plant area.
2.3.4 Sediment Contamination
Sediments in Woman Creek and South Walnut Creek were sampled in the fall of 1986, and in March
and October of 1989. Stations SED-28, SED-29. and SED.25 are located within the South Interceptor Ditch
in the Woman Creek drainage (Figure 2-12). SED-30 and SED-31 are seeps on the South Interceptor Ditch
berm near station SED-29. SED-27 and SED-26 are along Woman Creek just upstream of Pond C-2. Stations
SED-11, SED-12, and SED-13 are located along South Walnut Creek. SED-11 is the most upgradient station,
SED-12 is just upstream of Pond 8-1, and SED-13 is just downstream of Pond 8-5. Stations SED-1 and SED-2
on Woman Creek and an ephemeral tributary, respectively, are both downstream of OU 2, just west of Indiana
Street within the boundary of the buffer zone (east of area depicted by Figure 2-12).
2.3.4.1 Woman Creek Drainage
VOCs were detected in samples from the sediments in the Woman Creek drainage (Table A-14,
Appendix A). Chloromethane was present at SED-29 (SO pg/kg), and chloroform was reported at SED-31 (18
pgjkg). Several sediment samples contained methylene chloride and acetone at very low concentrations.
These compounds were frequently found in associated blanks. SED-30 contained 220 pg/kg acetone at one
sampling, but acetone was also present in the blank for this sample and was undetected in two other sampling
events for this station in 1989. Acetone and methylene chloride results in this area are believed to be
laboratory artifacts. The only other volatile organic compounds detected in the Woman Creek drainage
sediment samples were TCE (8 pgjkg) at SED-31 (estimated below detection limits elsewhere), and toluene
estimated below detection limit at SED-29 and SED-3D.

Of the metals, beryllium, lithium, silver, tin, and zinc were notably elevated above background in the
~
sediment of the South Interceptor Ditch and Woman Creek (Table A-15, Appendix A). Concentrations of silver
(as high as 49 mg/kg) are greater than five times the upper limit of the background range at stations SED-25.
SED-26. and SED-30. Beryllium was not detected in the background samples « 1.1 mg/kg) but occurs at
"
concentrations ranging from 3.8 to 15.5 mg/kg in all the sediment samples collected from the South Interceptor
Ditch and Woman Creek. Although tin was not above background «22.8 mg/kg) at SED-27, SED-28, and
SED-31, It occurred In a range from 364 to 1080 mg/kg in stations SED-25, SED-26. SED-29, and SED-30.
Concentrations of zinc (as high as 735 mg/kg) are greater than the upper limit.of the background range at
stations SED-11. SED-28, SED-29, and SED-30.
Plutonium was above background at stations SED-1. SED-2, SED-25, SED-26, SED-29, and SED-30,
ranging in concentration from 0.06 to 0.85 pCi/g (Table A-16. Appendix A). Contaminated surface soil from
the 903 Pad Area, transported primarily by wind, may be the source of this plutonium.
2.3.4.2 South Walnut Creek Drainage
The South Walnut Creek sediment monitoring stations include SED-11. SED-12 and SED.13. Only one
sample was obtained from each of SED-12 and SED-13 (13 August 1986). Due to prioritization of sampling
activities. additional samples were not collected from these stations. Table A-14, Appendix A shows that
acetone was reported for all three stations and was also associated with laboratory blanks. SED-11 was found
to contain TCE and 2-butanone at concentrations of 39 mg/kg and 12 pg/kg, respectively. All other VOCs
were either not detected or reported below detection limits for SED-11. SED-12 and SED-13.
As in the Woman Creek drainage, beryllium, lithium, silver. and tin are elevated in the sediments at
SED-11. They occurred at concentrations of 2.5.7.2, 15.0. and 404 mg/kg, respectively. Zinc was also notably
elevated, occurring at a concentration of 735 mg/kg (the upper limit of the background tolerance interval is
93 mg/kg). Uranium 235 was reported at a concentration of 0.2 pCi/g for SED-11 and americium levels were
reported at 0.19 pCi/g and 0.03 pCi/g for SED-12 and SED-13. respectively. Plutonium was also found at a

2.3.5
Surface Water Contamination
.~
Twenty-six surface water and surface seep stations in the vicinity of the 903 Pad. Mound. and East
Trenches Areas were sampled during field activities from 1986 through 1990 (see Appendix B). The following
discussion is based on all avaUabie data because many seeps or stream stations were dry during some
samplings. These data have been summarized in Appendix C and compared to ARARs (see Section 3 for
ARAR identification). Total radiochemical and metals data. although presented in the Appendix, are not
discussed because an assessment methodology that accounts for varying concentrations of suspended solids
is still being developed. Surface water monitoring locations are shown on Figure 2-12.
Flowing surface water in drainages was sampled at stations on the South Interceptor Ditch and Woman
Creek just upstream of Pond C-2 and at stations upstream of the B-series ponds on South Walnut Creek. The
B-series ponds were not sampled for this investigation. as they will be subsequently investigated as part of
another operable unit.
The surface water seeps are downslope and southeast of the 903 Pad Area. and downslope and north
of the Mound Area and East Trenches Areas. Because surface water at seeps and in streams represents
ground-water discharge (intermittent discharge with respect to streams). the surface water compositions are
similar to those of local ground water. The data for both media show that PCE. TCE. CCI.. and their
degradation products are the principal VOCs. and they show very similar major ion contents as well. However,
there is enough variability within stations so that it is not possible to demonstrate surface/ground-water
connections on a well-by-well. seep-by-seep basis.

2.3.S.1 Surface Water Stations Southeast of 903 Pad Area
".
There are several seeps downslope to the southeast of the 903 Pad. Surface water stations established
.J.
at these seeps in the 903 Pad Up Area are designated SW-SO, SW-S1, SW-S2, SW-SS, SW-S7, SW-S8, and
SW-77. Station SW-SO is closest to the 903 Pad, and SW-S7 and SW-S2 are south of SW-SO. SW-S1 and
SW-S8 are located in a ditch along the road east of SW-SO; however, overland flow of seepage from SW-SO,
SW-S2, and SW-S7 will also enter the ditch. Water in the ditch passes under the road south of these locations
through a. culvert. The discharge of the culvert is sampled at station SW-SS. SW-77 is another seep located
on the east side of the road, just north of SW-SS. It is noted, therefore, that SW-S1, SW-S8. and SW-S5 are
physically connected and likely receive flow from SW-SO, SW-S2. and SW-S7. Farther downgradient stations
include seeps at SW-53 , SW.02. SW~, and SW-&4; SW-27, SW-30, SW-S4. and SW-70 on the South
Interceptor Ditch; and SW-26. SW-28. and SW-29 on Woman Creek.
Data for seeps in the vicinity of the 903 Pad Up Site and farther downgradient at SW-S3, SW-63, and
SW-&4 indicate organic contamination. Contaminants in seeps in the vicinity of the 903 Up Site include 1,1.
DCE. 1.2-DCE. CCI.. TCE, and PCE, with concentrations of CCI. and TCE exceeding 1000 JJg/ t. Occasionally
1.2-DCE and TCE are present at SW-53. low concentrations of 00. and TCE «20 JJg/ t) occur at SW-63, and
low concentrations of TCE occur at SW-&4. Methytene chloride also occasionally occurs in these seeps. but
at concentrations near the detection limit, and frequently also occurs in the laboratory blanks. Low and very
infrequent concentrations of these and other VOCs occur at seep SW..o2 as well as at stations along the South
Interceptor Ditch. The water-quallty data for stations along the South Interceptor Ditch and Woman Creek do
not provide unambiguous evidence of contamination; however, the VOC concentrations in the upgradient seeps
suggest that a solvent plume within alluvial ground water is migrating to the southeast, which is consistent with
the alluvial ground-water flow direction. It is inferred that VOC contaminated alluvial ground water approaches
the South Interceptor Ditch and Woman Creek.
With respect to inorganic and dissolved radionuclide contamination. there are somewhat elevated
concentrations of TDS, major ions, aluminum, strontium, zinc, and uranium at most of these stations. Unlike
SU~ACE WATER INTERIM REMEDIAL ACTION PI.AN
ROO
-------
the absence of VOCs in surface water at stations along the South Interceptor Ditch (SW-70, SW-30, SW.54,
and SW-27), all have somewhat elevated uranium concentrations (generally less than 10 pCi/1 of total
uranium). These concentrations are usually above ARAR (5 pCi/1). Although the 903 Pad Area cannot be
~
ruled out as the source of the uranium, the occurrence of elevated uranium as far upgradient as SW-70
suggests the 881 Hillside Area as a potential source. Alluvial ground water at the 881 Hillside contains levels
.\.
of uranium above background.
Seeps in the vicinity of the 903 Pad Up Site (SW-SO, SW-53 , and SW-54) had detectable plutonium
and/or americium during one sampling event in 1989 (two events for SW-53). The samples contained
substantial suspended solids and were not filtered at the time of collection, and surface soils in the vicinity of
the seeps are contaminated with radionuclides. Furthermore. total radiochemistry data do indicate notably
higher plutonium and americium concentrations than in filtered samples. demonstrating that most of the
radionuclides are in a particulate form. Therefore, the local soils represent the most direct potential source for
seep contamination. However, there were traces of plutonium in a few ground-water samples (highest
concentration at well 15-87, 0.522 : 0.117 pCij 1) so ground water is also a potential source of radionuclides
in seeps, albeit a less significant one.
It Is noted that plutonium and americium are essentially insoluble in natural waters, but they can migrate
in colloidal form. and colloidal-size particles can pass through 0.45 pm filters such as those used in the
previous investigation (Puis and Barcelona. 1989). The DOE is currently conducting a study to assess the
distribution of plutonium and americium in surface water with respect to suspended solids particle size. The
study will include filtration of surface water through three pore sizes, and laboratory analysis for plutonium and
americium in the filtered and unfiltered fractions «0.10 pm, 0.10 #1m to <0.20 #1m, 0.20 #1m to <0.45 pm, and
2. 0.45 pm). Although this study was not explicitly designed to differentiate colloidal and dissolved
radionuclides, and therefore will be unable to quantify colloidal material under 0.' #1m, it will demonstrate
whether a significant portion of the radionuclides are between 0.' and 0.45 pm and thereby provide some
indication of the Importance of colloidal transport. Also, if most of the plutonium is particulate in nature
(>0.1 pm in size), it is likely plutonium can be removed from surface water by unit processes effective at
removal of suspended solids, e.g., sedimentation and filtration.

contaminants, but the data do not allow this conclusion to be drawn with certainty. These stations also
frequently have surface water concentrations above ARARs for TDS and uranium. The TDS and uranium
concentrations are typical of the alluvial ground water in the vicinity of the 903 Pad and Mound Areas. CCI.,
PCE, TCE-, and elevated zinc are also present in the alluvial ground water at the Mound Area.
The only datum available for Station SW-23 (August 1986 sampling) shows an absence of VOCs.
Although there are no August 1986 data for the upstream stations, the data suggest the organics have
volatilized over this reach.
2.3.5.3 Seeps at the East Trenches Areas
Of the two seeps at the East Trenches Areas (SW-65 and SW-103), SW-65 has no apparent organic
contamination, and SW-103 has the constant presence of CCl4 at concentrations less than 10 JJg/ I. Dissolved
uranium was also above ARAR at SW-65. Uke the 903 Pad and Mound Areas, the chemistry of these seeps
is similar to the localized ground water.
2.3.6
Air Contamination
The 903 Pad Area is recognized as the principal source of airborne plutonium contamination at the RFP.
An extensive air monitoring network known as the Radioactive Ambient Air Monitoring Program (RAAMP) is
maintained at the Plant in order to monitor particulate emissions from the 903 Pad Area and other Plant
facilities. Historically, the particulate samplers located immediately east. southeast. and northeast of the 903
Pad. Mound, and East Trenches Areas have shown the highest plutonium concentrations. This finding is
corroborated by the results of soil surveys which indicate elevated plutonium concentrations to the east.

particular1y southeast of the area. However, RAAMP has found ambient air samples for plutonium to be well
within the DOE guidelines of 20.0 x 10" pCi/ I established for the protection of human health (Rockwell
International. 1987b).
..
2.3.7 Summarv of Contamination
The Phase I RI investigations of environmental media lead to the general conclusions that volatile
organic aAd radionuclide contamination exists in solis. surface water and ground water around several au 2
IHSSs. and that the distribution and magnitude of the contamination can be better delineated via sampling and
analysis planned for the Phase II investigation.
TCE. PCE and ca. are the principal organic contaminants in surface and ground waters. with lesser
amounts of their degradation products and other compounds at numerous sampling sites throughout au 2.
Plutonium and americium In surface water samples are other apparent Indicators of RFP~erived contamination.
Several metals and other inorganic constituents (including uranium) are also above background in the
environmental media. but the data do not permit unambiguous conclusions with regard to contamination. The
uncertainty results in part from the absence of clear concentration gradients and from the limited knowledge
of the inorganic composition of waste sources in OU 2. Natural processes (e.g.. evaporative concentration)
may govern the source and distribution of such inorganic constituents. This will be further investigated in the
context of long-term remediation at OU 2.
2.4
ANALYTICAL DATA
Organic. inorganic and radionuclide contaminants exist in au 2 surface water. Volume II (Appendix B)
presents a compilation of volatile organic. inorganic and radiochemistry data for all surface water stations at
au 2 that are available at this time. Only a small fraction of the data have been validated; they are identified
in the appendices by a qualifier adjacent to each datum. The qualifiers "V' (valid), "A" (acceptable with

qualifications). and "R" (rejected) are assigned in accordance with the ER Program Quality Assurance/Quality
Control (QA/QC) Plan (Rockwellintemational. 1989b). Rejected data either did not conform to the QA/QC
"
procedures. or insufficient documentation exits to demonstrate conformance with these procedures. These
data. at best. can only be considered qualitative measures of the analyte concentrations. The schedule for the
1M/IRA does not permit waiting for all data to be validated. However, the validated data and their similarity
'-
to unvalidated data are considered sufficient to justify and to define the general configuration of the 1M/IRA.
2.5
SITE CONDITIONS THAT JUSTIFY AN 1M/IRA
As discussed in Section 1, there is no immediate threat to the public health and environment posed by
surface water contamination in South Walnut Creek Basin. The affected surface water is contained within the
plant boundary by existing detention ponds. and is treated and monitored prior to discharge. There is,
however, potential for an imminent threat to develop and implementation of this 1M/IRA will reduce the
likelihood that such a threat will result by enhancing DOE's efforts to manage contaminated surface water.
Although downstream safeguards are provided by the B-Ponds, this 1M/IRA should reduce the potential for off.
site migration and uncontrolled releases of contaminated surface water by reducing contaminated surface water
loading to the Ponds. In addition. by collecting contaminated surface water through diversions at the sources,
this 1M/IRA will mitigate downstream migration of contaminants and could reduce the size and cost of future
RFP remedial actions. Such an action is consistent with the goals for a final remedy at the site.
This 1M/IRA focuses only on controlling the migration of hazardous substances in South Walnut Creek
Basin surface water and does not address soil or ground-water contamination. An au 2 Phase II RI Plan has
been prepared to further characterize the extent of contamination in preparation for further remedial actions
at OU 2.

SECTION 3
IDENTIFICATION OF INTERIM REMEDIAL ACTION OBJECTIVES
..
3.1
SCOPE OF INTERIM MEASURES/INTERIM REMEDIAL ACTION
..a
The overall objective of the South Walnut Creek Basin 1M/IRA at OU 2 is the mitigation of downgradient
contaminant migration within surface water by means of the collection and treatment of contaminated surface
water to ~chieve, to the extent practicable, ARMs (see Section 3.3). ARARs are used in defining the
remediation goals for the Interim action. Based on the meetings between DOE, COH, and EP A during February
and March 1990, and comments received during the public comment period, DOE is proposing this 1M/IRA
Plan which specifies point source locations for the collection of contaminated surface water, and provides for
the collection and treatment of flows exclusive of those resulting from high precipitation events.
3.2
INTERIM REMEDIAL ACTION SCHEDULE
Revisions to this plan based on public comment, preparation of a Responsiveness Summary pursuant
to the public meeting, treatabDIty studies, and design and implementation of this 1M/IRA will occur through
Spring 1991. MDestone dates for specific activities are presented in Table 0-', Appendix O. Table 0.' shows
the milestone schedule as proposed in the draft FFACO/IAG (DOE, 1990a).
3.3
COMPUAN9E WITH APPUCABLE OR RELEVANT AND APPROPRIATE REQUIREMENTS (ARARs)
AND PROTECTION OF HUMAN HEALTH AND THE ENVIRONMENT
The NCP [FR Vol 55, No. 46, 8848; 40 CFR 300.430 (e)] requires that, in development of alternatives
for final remediation, the following be considered:
1.
ARARs;
2.
for systemic contaminants, concentration levels that will not cause adverse effects to the human
population and sensitive subgroups over a lifetime of exposure;

5.
for current or potential sources of drinking water, attainment of Maximum Contaminant Level
Goals (MCLGs) or Maximum Contaminant Levels (MCLs), if MCLGs are zero: and,
..
6.
attainment of Oean Water Act (ONA) water quality criteria where relevant and appropriate.
The lAG. in paragraph 150. states "Interim Remedial Actions/Interim Measures shall. to the greatest extent
practlcabte, attain ARARs." Also for Interim actions, the NCP [40 CFR 3OO.430(f)] specifically notes that an
ARAR can be waived if the action is to become part of the final remedy that will attain ARARs. The results of
the treatability studies identified in Section 6.4 will allow evaluation of the extent to which the 1M/IRA will attain
ARARs. I.e.. It may not be practicable to attain all ARARs for this Interim action and ARAR waivers or altemate
concentration limits may be requested after the study is completed.
This section identifies and analyzes ARARs relevant to the South Walnut Creek Basin 1M/IRA and
discusses how the action will be protective of human health and the environment. This remedial action is
considered an on-site 1M/IRA to be administered under CERCLA; therefore. only substantive and not
administrative requirements of regulations (such as RCRA) apply. Permits. for example. are not required (per
paragraph 121 of the lAG).
"Applicable requirements," as defined in 40 CFR 300.5. means "those cleanup standards. standards of
control, and other substantive requirements. criteria. or limitations promulgated under federal environmental
or state environmental or facility siting laws that specifically address a hazardous substance, pollutant.
contaminant. remedial action. location, or other circumstance found at a CERCLA site. Only those state
standards that are identified by a state in a timely manner and that are more stringent than federal requirements
may be applicable." "Relevant and appropriate requirements: also defined in 40 CFR 300.5. means "those
cleanup standards. standards of control. a.nd other substantive requirements, criteria. or limitations promulgated


under federal environmental or state environmental or facility siting laws, that, while not "applicable" to a

site, address problems or situations sufficiently similar to those encountered at the CERCLA site that their use
is well suited to the particular site. Only those state standards that are identified in a timely manner and are
..
more stringent than federal requirements may be relevant and appropriate." In addition to applicable or
relevant and appropriate requirements, advisories. criteria, or guidance may be identified to be considered
.#
(TSC) for a particular release. As defined in 40 CFR 3oo.4OO(g)(3), the "to be considered" (TSC) category
consists of advisories, criteria. or guidance developed by EPA. other federal agencies. or states that may be
useful in developing remedies. Use of -rSCs" is discretionary rather than mandatory as Is the case with
applicable. or relevant and appropriate requirements.
In general. there are three categories of ARARs. These categories are:
.
Ambient or chemical-specific requirements
.
Location-specific requirements
.
Performance, design. or other action-specific requirements
Each category is discussed in more detail below.
3.3.1
Ambient or Chemical-Scecific Reauirements
Ambient or chemical-specific requirements set health- or risk-based concentration limits in various
environmental media for specific hazardous substances or pollutants. These requirements set protective clean-
up levels for the chemicals of concem in the designated media. or indicate a safe level of air emission or
wastewater discharge. The chemical-specific ARARs identified herein are used in defining the remediation
908ls for clean up of contaminated surface water and discharge of treated water.
ARARs are derived primarily from federal and state health and environmental statutes and regulations.
The following may be considered when establishing clean-up standards, but are not considered ARARs: Health
Effects Assessments. Health Advisories, Chemical Advisories, and Guidance Document criteria. These and any

proposed standards are classified as items to be considered, or TBCs. Where background concentrations for
constituents are above the ARAR for that constituent. a waiver from the ARAR may be appropriate. A summary
.
of ARARs for the contaminants found in South Walnut Creek Basin surface water at au 2 are presented in
Appendix E, Tables E-1.1 through E-1.4. Tables E-1.1, E-1.2, E-1.3, and E-1.4 present ARARs for volatile
organics, metals. conventional pollutants, and. radionuclides. respectively and will be applied to operations
~.
involving water treatment effluent.
As"discussed in 55 FR8741, when more than one ARAR has been Identified for a contaminant, the most
stringent standard has been Identified as the ARAR which the 1M/IRA will attain to the greatest extent
practicable. Where no ARAR standard exists, a TBC standard has been identified which the 1M/IRA will treat
as a goal to achieve.
An ARAR analysis for volatile organics. metals. conventional pollutants. and
radionuclides. respectively. is presented in Tables E-2.1. E-2.2, E-2.3. and E-2.4. The screening process
includes consideration of both ground-water and surface water standards because of the p."ooable interaction
of alluvial ground water and surface water in the drainages of the RFP. Of the elements/compounds detec!ej
in South Walnut Creek Basin surface water at au 2, there are no ARARs for calcium, magnesium, potassiur:.
sodium, bicarbonate, and strontium.
However. the TDS ARAR establishes the acceptable aggregate
concentration for the above major ions (excluding strontium). Although no ARAR or TBC exists for strontium,
an objective of this 1M/IRA will be to reduce strontium to background levels.
3.3.1.1 Safe Drinking Water Act Maximum Contaminant Levels (MCLs) and MCL Goals
Because South Walnut Creek Basin surface water at au 2 is a source of drinking water, MCLs are
relevant and appropriate for all phases of the 1M/IRA. MCLs are derived from the Safe Drinking Water Act
(SDWA) (PL 93-523). They represent the maximum permissible level of a contaminant in water which is
delivered to the free-flowing outlet of the ultimate user of a public water system [40 CFR 141.2(C)). Per the

3.3.1.2 Ambient Water Quality Criteria
~
The Ambient Water Quality Criteria (AWQC) are non-enforceable guidance developed under the CWA.
Guidance is set for surface waters for the protection of aquatic life and for the protection of human health.
..
based on consumption of both drinking water and aquatic organisms from that water. The proposed 1M/IRA
involves treatment and discharge to surface water that has a use-protected designation. aquatic life Class II
warm water classification. Although not ARAR, per the new NCP, the AWQC are considered as relevant and
appropriate preliminary remediation goals. Final remediation goals wUI be set according to ARARs and for total
risk due to carcinogens that represent an excess upperbound lifetime cancer risk to an individual to between
10" to 1 0041 lifetime excess cancer risk when the final remedy is selected for all of OU 2.
3.3.1.3 Colorado Surface and Ground-Water Quality Standards
The Colorado Water Quality Control Commission (WQCC) has proposed ground-water quality standards
for many compounds for protection of both human health and agricultural uses. These proposed standards
are considered TeC since they are not enforceable standards untO RFP's ground water is classified by the
WQCC. Where standards exist for both human health and agricultural uses. the more stringent standard is
selected as TBC.
Permanent surface water quality standards have been adopted by WQCC for Walnut Creek. These
include standards for many organic. inorganic and radionuclide parameters. These standards went into effect
March 30. 1990. and are considered applicable to this interim remedial action.
For both ground water and surface water standards. some of the standards are lower than the current
standard detection limits for the constituents. When this occurs. the WQCC Practical Quantitation Umit (POL)
will be considered as the ARAR.

RCRA Ground-Water Protection Standards
-.
Owners or operators of facilities that treat. store, or dispose of hazardous waste must ensure that
hazardous constituents listed in 6 CCR (Colorado Code of Regulations) 1007-3 and 40 CFR 261. Appendix VIII,
entering the ground water from a regulated unit do not exceed concentration limits under 6 CCR 1007-3 and

40 CFR 264.94. The concentration limits include standards for 14 compounds. with background' or alternate
.
concentration limits (ACLs) , used as the standard for the other RCRA Appendix VIII constituents. These
concentrat~on limits apply to RCRA-reguJated units subject to permitting Oandmls. surface impoundments. waste
piles, and land treatment units) that received RCRA hazardous waste after July 26, 1982. Although this area
does not contain RCRA-regulated hazardous waste management units. it does contain IHSSs. As a result,
these RCRA (Subpart F) regulations are considered relevant and appropriate for ground water remediation.
These requirements are not applicable or relevant and appropriate with respect to the proposed interim
remedial action in that they do not specifically address the collection. treatment, and discharge of surface
waters nor are these activities sufficiently similar to the circumstances regulated by the RCRA Subpan F
requirements to be relevant and appropriate. RCRA ground-water protection requirements relate specifically
to protection against degradation of the uppermost aquifer by a regulated unit, or a solid waste management
unit (SWMU) in the case of Corrective Action activities. which clearty do not relate to the collection, treatment.
and discharge of surface waters. whether or not such waters have been affected by the introduction of ground
water through seeps. The RCRA ground-water requirements do provide an effective mechanism for the
protection of the uppermost aquifer and, consequently, potential drinking water sources. Accordingly. since
- ..
effluent discharges could potentially affect downstream drinking water sources, the Subpart F requirements
have been included as TBC for surface water. Background concentrations for 40 CFR 264. Appendix IX
constituents not listed in Appendix VIII are also TBC for surface water.
TBC background surface water values for RCRA Subpart F are applied u$ing maximum concentrations from background surface
water at RFP.

3.3.1.5 Protection of Human Health and the Environment
..
As Ulustrated by the hazard quotients and carcinogenic risks listed in Tables E-1.1 through E.1.4,
achieving the ARARs should result in a clean-up action that is protective of human health and the environment.
~.
For non-carcinogens, the protectiveness goal is a hazard index of 1. The hazard index is the sum of the
hazard quotients [i.e., the estimated daily intake (dose) to reference dose ratios) for all of the contaminants
combined, which have been computed and are presented in Table E-1. In assessing non-carcinogenic risk,
a hazard Index of one or less is considered to be acceptable. If the hazard index exceeds one, it indicates
that there might be the potential for adverse non-carcinogenic health effects occurring. Unlike the method
used to evaluate the potential for carcinogenic toxicity, the hazard index does not indicate the probability of
adverse health effects occurring, but it is used as a benchmark for determining where there is a potential
concern. With respect to carcinogens, cumulative cancer risk should be less than 10" (individual cancer risks
shown in Table E-1 are considered additive). As noted in Table E-1, the calculated incremental cancer risks
exceed 10" for some of the organic carcinogens as well as for arsenic and beryllium. However, the cancer
risks are computed on the basis of the detection limit and therefore can only be considered a possible
maximum carcinogenic risk; the actual risk is unknown but likely to be considerably lower. Removing these
contaminants to non-detectable levels and attaining, to the extent practicable, the other ARARs, the 1M/IRA
is considered protective of human health and the environment.
3.3.2 Location-Scecific Reauirements
Location-specific ARARs are limits placed on the concentration of hazardous substances or the conduct
of activities solely because they occur in certain locations. These may restrict or preclude certain remedial
actions or may apply only to certain portions of a site. Examples of location-specific ARARs which pertain to
the 1M/IRA are federal and state siting laws for hazardous waste facilities (40 CFR 264.18, fault zone and
floodplain restrictions), and federal regulations requiring that actions minimiZe or avoid adverse effects to
wetlands (40 CFR Part 6 Appendix A and 40 CFR Parts 230-231).

3.3.3 Performance. Oesian. or Other Action-SDecific Reauirements
Performance, design, or other action-specific requirements set controls or restrictions on particular
kinds of activities related to management of hazardous substances or pollutants. These requirements are not
triggered by the specific chemicals present at a site. but rather by the particular 1M/IRA alternatives that are
evaluated as part of this plan. Action-specific ARARs are technology-based performance standards. such as
the Best Available Technology (BAT) standard of the Federal Water Pollution Control Act. Other examples
include RCRA treatment, storage, and disposal standards, and Clean Water Act pretreatment standards for
discharges to publicly-owned treatment wort

at the sources. The treatment technologies are presented and evaluated in Section 4.4. The treatment system
designs presented In Section 4.4 are conceptual. with only enough detaR to determine relative costs. Detailed
design and costing for the 1M/IRA wli be conducted after the results of the bench and field-scale treatability
studies are obtained. T~ comparative cost evaluations employ a standard 3O-year basis for present worth
analysis. However. the actual service life of the South Walnut Creek Basin Surface Water 1M/IRA is not known
at this time. The 1M/IRA coUd, tor example. become a part of the long-term OU 2 remedial action. Lastly,
all solid waste generated during the 1M/IRA. with the exception of activated carbon (e.g., filter cake, excavated
soils from installation of the surface water diversion and collection structures. and sediments accumulating in
the collection system during operation) will be characterized and handled according to the RFP waste
management operating procedures. For costing purposes, however, It is assumed that these wastes will be
handled and disposed as low-level mixed waste.

4.1.1
Surface Water Collection T echnoloaies
'"
Figure 4-1 Ilustrates the locations of the South Walnut Creek Basin surface water seeps and in-stream
monitoring stations. As mentioned In Section 1.0, general agreement between EPA, CDH and DOE was
reached on the specific locations for collection of contaminated surface water. These locations are designated
.
in Figure 4-1 as the 81M/IRA Surface Water Monitoring Stations8 and Include SW-56. SW-59. SW~, SW~1,
SW-101, and SW-132. It was agreed that flows at these stations would be collected either at the stations or
immediately downstream at a point of confluence. Figure 4-2 offers a detaled plan view of the locations of
SW-59. SW-6). SW~1, SW-132. and SW-133In the South Walnut Creek drainage. Contaminated water in the
drainage uttlmately enters Pond 8-5 via Pond 84.
At the meetings In February and March 1990 between DOE and the regulatory agencies, seep SW-103
was also targeted for collection. It is located within the South Walnut Creek Drainage upstream of Pond 8-5
(Figure 4-1). The seep contains trace concentrations of CO. ( < 10 ug/ l) and concentrations of total plutonium,
americium, uranium. and several metals above ARARs. However, at the time, the physiographic features of
the seep were not discussed. Of particular note is the large area of seepage (approximately 30,000 sq. ft.) and
the location of the seep on a steep hllside. These features necessitate an elaborate drainage system for
seepage collection that would require disturbance of large areas of potentially contaminated saturated soils
which would likely result in release of significant quantities of contaminants downstream. Construction at
SW-103 would also have a negative impact on the large area of wetland present at this seep. For these
reasons, and because the ca. and dissotved inorganic constituent concentrations in the seepage are low, and
the contribution of radionuclide and metals contamination from SW-103 to the South Walnut Creek drainage
above the detention ponds Is likely to be Insignificant relative to that resulting from contaminated surface water
runoff. collection of water at this seep is no longer recommended for this 1M/IRA. Since the environmental
impacts of construction of a surface water collection system at SW-103 appears to outWeigh the benefits of
collecting and treating this seepage, consideration of collection at SW-103 is deferred until additional
hydrogeological and contaminant characterization information is gathered and assessed during conduct of the
Phase II RFI/RIFS Alluvial Wort< Plan for OU 2.

Several alternatives exist for collecting the contaminated South Walnut Creek Basin surface waters
mentioned above. First and foremost Is collection of surface water by diversion at the source. This technique
...
employs existing or newly constructed diversion structures at the seep or in-stream stations to divert the
surface water into collection sumps. This method of surface water collection was agreed to by EPA, COH, and
..
DOE in the February and March 1990 meetings. This technique will be further discussed and evaluated In
Section 4.3. For comparative purposes, two other surface water collection methods are discussed below.
A ~ond method of surface water collection is by ground-water withdrawal using an upgradient well
array or french drain. This technique lowers the ground-water table and eliminates seepage. allowing
separation of contaminated ground water (seepage) from surface water runoff. e.g., at SW-59. However. the
hydrogeology at OU 2 is not adequately understood to design an effective ground-water withdrawal system.
For example, It is not known whether the seepage Is due to water originating in the Rocky Flats Alluvium and
being released to the surface through colluvium because of slope changes and/or bedrock highs. or whether
the source of the water is bedrock sandstone subcropping in this vicinity. This information is critical to the
design of an effective ground water withdrawal system. EPA alluded to the issue in their transmittal letter
(January 9. 1990) which accompanied their comments on the draft OU 2 ground-water 1M/IRA Plan, wherein
they stated". . . this OU Is difficult to address on an Interim basis due to the lack of comprehensive quality data
characterizing the nature and extent of contamination. It Is uncertain whether the most probable imminent
threat. the alluvial ground-water system, can be effectively addressed at this time." For this reason. collection
of surface water by ground-water withdrawal is eliminated as a reasonable alternative for this 1M/IRA and will
not be considered for further detaled evaluation.
A third collection alternative Is to allow the contaminated surface water to continue to flow through the
South Walnut Creek drainage into detention Pond 8-5. The contaminated South Walnut Creek 8asin surface
water. along with all other waters collected and detained in Pond 8-5 would be transferred from the Pond for
treatment. This method has three primary drawbacks. First, there is a potential threat of transferring the
surface water contaminants to ground waters within the South Walnut Creek drainage basin via infiltration.
Secondly. release of VOCs to the atmosphere will occur while the surface water is in transit to detention Pond

8-5. Finally, allowing the South Walnut Creek 8asin surface waters to mix with other waters retained in Pond
8-5 generally increases the volume eX dYute contaminated water at the RFP facUity that may require treatment.
.,.'
For these reasons, collection of South Walnut Creek Basin surface waters at detention Pond 8-5 is eliminated
as a reasonable alternative for the 1M/IRA and will not be considered for further detailed evaluation.
.
4.1.2 Surface Water Treatment Technoloaies
~sed on the objectives of the Surface Water 1M/IRA discussed In Section 3.1, Table 4-1 has been
prepared to establish the basis for conceptual design for surface water treatment. The influent constituent
concentrations listed In Table 4-1 are estimated from a flow-weighted maximum concentration model based
on the maximum constituent concentrations observed at the SW-59 and SW~1 collection points. The flow
values used to weight the maximum concentrations used in the model are the corresponding collection system
design flows (established In Section 4.3 and listed in Table 4-5). A spreadsheet Dlustrating computation of the
flow-weighted maximum concentration computation is shown in Table F-1, Appendix F. To be conservative,
the maximum constituent concentrations used In the model for SW~1 also Includes maximum observed
concentrations for the group of stations upgradient of SW~1 (i.e., SW-56, SW~, and SW-1 01). Unfortunately,
station SW-132 was only recently assigned to the au 2 surface water sampling program and concentration
data for this discharge are not avaUabie for use In the treatment system design model. As discussed in
Section 1, however. the water quality characteristics of this stream are expected to be simRar to that at SW~1.
This assumption has been used to provide a reasonable conceptual treatment system design basis in the
absence of SW-132- dat8. The design basis will be updated as SW-, 32 concentration and flow data become
available to verify the Influent concentrations computed herein.
Table F-1 shows that strict application of the flow weighted concentration model predicts vinyl chloride,
methylene chloride and acetone influent concentrations above their respective ARM values. However,
examination of the surface water data presented in Appendix B reveals that these constituents are not likely

to be present in the influent at levels above ARAR. Vinyt chloride, methytene chloride and acetone were
detected at levels above ARAR only at stations SW-56. SW~ and SW-101. However, as proposed in

Section 4-3. contaminated surface water from these stations wUl be collected at the downstream station SW~1

and/or were also present in the associated laboratory blanks. These compounds are, therefore, not included
in the basis for design of the surface water treatment plant. The effluent concentrations listed In Table 4.1
correspond to the ARAR for each constituent.
Treatment technologies for radionuclides and metals removal that are considered In this 1M/IRA Plan
include chemical precipitation, cross-flow membrane filtration, and Ion exchange. Uquid-phase Granular
Activated Carbon (GAC) adsorption, air stripping with liquid and vapor phase GAC adsorption, and ultraviolet
(UV) /peroxide oxidation are considered for VOC removal. Many treatment units suitable for removal of VOCs
and radionuclides from water require that suspended solids be removed from the influent to prevent
performance degradation and/or fouling. Removal of suspended solids down to the 1 pm particle size range
ensures optimum treatment system performance. The two candidate influent pretreatment alternatives for
removal of suspended solids considered for this 1M/IRA are cross-flow membrane filtration and polymer
addition with granular media filtration In a continuous backwash filter. Pretreatment Is also a vehicle for
removal of particulate radionuclldes and metals and. with chemical addition. should facHltate precipitation and
adsorption of soluble radionuclldes and metals.

Effectiveness
The crtteria for effectiveness evaluation of remedial alternatives Includes protection and the use of
~
alternatives to land disposal. Protection includes protection of the community and workers during the remedial
action; threat reduction; length of time untU protection is achieved; compliance with criteria. advisories and
.
guidance; risk of potential exposure to residuals remaining on site; and continued reliability over the life of the
1M/IRA. The effectiveness crtterla also Includes use of alternatives to land disposal. thus promoting treatment
or recycling. In addition. the alternatives will be evaluated wtth respect to reduction of toxicity, mobility, and
volume of wastes per the March 1990 NCP.
4.2.2 Imclementabilltv
The criteria for implementabillty evaluation of remedial alternatives includes technical feasibility.
availability. and administrative feasibUIty. Technical feasibAIty Includes the abUityto: construct the technology;
maintain Its operation; meet process efficiencies or performance goals; demonstrated performance; evaluate
Impact of environmental conditions; and comply with the SARA requirement that removal actions should
contribute to the efficient performance of long-term remedial action to the extent practicable. AvaUabUIty
Includes the avalability of necessary equipment, materials and personnel; avaUabillty of adequate off-site
treatment, storage, and disposal capacity, If appropriate; and description of post-remedial site controls which
wDl be required at the completion of the action. Administrative feasibility Includes the likelihood of public
acceptance of the alternative, Including site and local concern; coordination of activities with other agencies;
and ability to obtain any necessary approvals or permits.
4.2.3 ~
The criteria for evaluation of remedial alternative cost includes total cost and statutory limits. T ota! cost
includes direct capital costs, indirect capital costs, and operating and maintenance costs. Since the surface
water 1M/IRA at au 2 is not an EPA-financed remedial action. the $2 million statutory cost limit does not apply.

EVALUATION OF THE IM/IRA SURFACE WATER COLLECTION SYSTEM
~
As discussed eartler. South Walnut Creek Basin contaminated surface waters will be collected by
diversion at the sources. This section further describes this technique as It applies to the surface water seep
..
and In-stream monitoring stations considered in this 1M/IRA. This presentation includes a discussion of the
anticipated seep and In-stream monitoring station flows. and an evaluation of the collection technique per the
evaluation process outlined In Section 4.2.
4.3.1
Surface Water Collection bv Diversion at the Sources
4.3.1.1 Description
Figure 4-3 shows the locations of ~ surface water diversion and collection systems proposed for the
1M/IRA. The collection systems (05s) are denoted 05-59. CS~1. and CS-132. The proposed location of the
surface water treatment plant Is also Indicated on Figure 4-3. The CSs provide for automatic pipeline transfer
of the collected surface water to the treatment system.
Design flow rates for surface water collection systems CS-59. CS~1. and 05-132 are based on flows
from stations SW-59. SW~1. and SW-132. respectively. The design flow rates are maximum flows observed
in the 1988. 1989, and 1990 field investigations. excluding flows related to high precipitation events. Only
design flows wli be collected from the South Walnut Creek Basin surface water monitoring stations. Historical
flow data for SW-59 are listed In Table 4-2. Table 4-2 lists only two flow rates of sufficient quantity to be
measurable for SW-59 (each 4.5 gallons per minute [gpm)). Rocky Rats personnel have observed flows at
SW-59 monthly since Spring 1990. They report that a flow of approximately 0.5 gpm was occurring at each
observation. It Is expected that all flows at SW-59 will be diverted for treatment.
Historical flow data for SW-61 are listed in Table 4-3. Table 4-3 Indicates two high flow events for SW-
61 of 166 gpm. All other historical flow data for SW-61 are below 36 gpm. To complement the historical data

and to obtain wet season flow data not corresponding to a major precipitation event, a flow measurement at
SW~1 was obtained In April 1990. A cutthroat flume manufactured by Bask! Water Instruments, Inc. was used
~
to measure the flow at SW~1. A flow of 37.5 gpm at SW~1 was recorded.
Historical flow data are not avaUabie at SW-132 as this Is a newty designated monitoring station.
.'
However, It was observed during October 1990 and December 1990 field surveys that the flow at SW-132 was
approximatety equal to the flow at SW-«J. The design flow rate for CS-132 wil thus be based on historical flow
data for SW-«J. Table 4-4 Indicates a maximum observed flow of 18 gpm for SW-«J.
Based on the historical data avaBabie and the April 1990 field measurement, design flow rates and
average annual withdrawal rates for each of the collection systems were established. The design and
withdrawal flow rates are presented In Table 4-5. A design flow of 37.5 gpm is assigned to SW-61. This flow
represents an above-everage precipitation wet season flow not corresponding to a major storm event. The
historical maximum flow for SW-59, 4.5 gpm, is used as the design basis for the collection system at this seep.
A design flow of 18 gpm Is assigned to 0$-132 based on the historical maximum flow observed at SW~.
Average annual withdrawal rates shown in Table 4-5 are estimated as follows: For SW~1, the historical flow
data spanning the 12-month period of March 1989 to March 1990 (See Table 4-3) is averaged. In the averaging
process 37.5 gpm, the design withdrawal rate at SW-61, Is substituted for 166 gpm for the 3/20/89 and
3/12/90 recorded measurements. This calctUtlon gives an annual average withdrawal rate of approximately
14 gpm. Averaging the historical flow data for SW-59 (See Table 4-2), the annual average withdrawal rate at
SW-59 Is found to be 8PProxImately 1 gpm. As with the design flow rate for SW-132. the annual average
withdrawal rate for SW-132 wli be estimated from historical flow data at SW-«J. Averaging the historical flow
data at SW-«J gives an estimate of the annual average withdrawal rate of 5 gpm at SW-132.

The flows from SW-«) and SW-133 wHI be collected at the downstream station SW~1 by a new surface
water diversion weir and pump station. A schematic of an example surface water diversion and collection
system is illustrated In Figure 4-4. The weir at SW~1 wUI serve to diven up to 37.5 gpm from the drainage.
-.-
Contaminated surface water wUI flow from upstream of the weir to a manhole and sump. For cost estimating
purposes, It will be assumed that a 1,ooo-gaJlon capacity, precast concrete sump will be used at CS~1.
Submersible pumps Installed in the sump along with a level control system wli automatically transfer collected
..
water to the treatment facUity. The pumping capacity wBl be designed to accommodate the 37.5 gpm design
flow. If the Inflow Into the pump station manhole exceeds the pumping rate, however, the excess flow will
return through overflow piping to the drainage immediatefy downstream of the CS~1 weir. The seep flow from
SW-59 Will be Isolated from the South Walnut Creek drainage and collected separately from CS~1 by
diversion into a sump. For cost estimating purposes, It is assumed that a 5OO~lon capacity,precast concrete
sump will be used. Submersible pumps and level controls will automatically transfer the collected water to the
treatment system. The pumping capacity wUI be designed to accommodate the 4.5-gpm design flow for CS-59.
Although unlikely, If the Inflow to the CS-59 pump station exceeds the pumping capacity, the excess flow will
be discharged to South Walnut Creek via an overflow pipe. The overflow wUI enter South Walnut Creek
upgradient of CS~1 and will either be collected by, or allowed to pass, CS~1 depending on whether the creek
flow Is less thein or greater than the 37.5 gpm design flow for CS~1. The flow at SW-132 will be collected and
transferred to the treatment system In the same manner as for flow at SW~1. CS-132 wUI be designed,
however, to divert and collect 18 gpm. For cost estimating purposes, a 1,OOO-galion pre-cast concrete sump
will be used.
All sumps and pipes will be provided with secondary containment to meet RCRA tank regulations.
Pipelines will be heat traced and Insulated to prevent freezing in the winter.

threats to human health and the environment is achieved by diverting, collecting, and treating contaminated
surface waters at or near the source. Downstream contaminant migration via surface water and ground water
and release of VOCs to the atmosphere is minimized with this surface water collection system. The
..
implementation of this collection action should not adversely affect the safety of nearby communities, and the
risk to the environment should not be increased.
..
The surface water is collected and automatically transferred to the treatment system with little
opportunity for worker contact. As a result worker exposure to potentially contaminated surface water is
minimized. Where worker exposure to surface water occurs (i.e., sediment removal), pumping equipment
minimizes contact time, and standard personal protective equipment will offer a high degree of protection.
Residuals (Le., collected sediments) will not remain on site; they WIll be treated or disposed according
to the standard RFP waste management procedures and project-specific SOPs. The SOPs will be prepared
after the 1M/IRA design is finalized to address specific waste handling activities. The collection structures are
simple in design, and will require little periodic preventive maintenance to ensure continued reliability over the
life of the 1M/IRA.
4.3.1.3 Implementability
The equipment and materials required to construct the surface water diversion and collection systems
are standard and readily available. The systems are standard in design and do not require special skills for
installation. Sump installation may result in disturbance of potentially contaminated soils and potential impact
to the environment by release of contaminated dust to the atmosphere and release of contaminated soil via
surface water runoff. This impact will be minimized by implementing project-specific health and safety plan
procedures during construction (e.g., dust suppression, windspeed monitoring/construction shutdown). The
health and safety guidance documents pertinent to this 1M/IRA Plan are discussed in Section 7. The proposed
collection system locations are easily accessible and power exists in the area. Since the collection systems

are simple In design they should offer reliable and relatively malntenance-free operation over the life of the
1M/IRA. ManhcHs and sumps will require periodic cleaning to remove accumulated solids.
..
4.3.1.4 Costs
~"
Assumed capital and operating costs for the surface water diversion alternative are shown In Table 4~.
The collection system can be constructed for $203,500. wtth annual operatJon and maintenance costs of
$14,600. At an interest rate of 10 percent and an operating life of 30 years, the present worth of this system
is approximately $341,100.

Annual collection system cleaning costs are based on 32 manhours of labor at S60/hr. Collection system cleaning involves
removal of sediments that build up in the sumps and behind the diversion weirs.
8
To be conservative, it is estimated that sediments recovered from collection system cleaning will be disposed of as hazardous
mixed waste ($450 per cubic yard transportation and disposal costs at the Nevada Test Site). The cost estimated is based on
approximately 9.5 cubic yards of sediments recovered annually. This waste volume is based on an average suspended solids
concentration of 350 ppm (see Section 4.4.1.1). It is assumed that approximately 20 percent of the suspended solids in the
surface water will accumulate in the collection system sumps and trenches. and the resulting waste will be 30 percent solids by
weight.
7
Annual pipeline maintenance costs are based on 100 manhours of labor at S60/hr.
8
Annual electrical power costs are based on two 3-hp (CS-61 and CS-132) and one 1-hp (CS-59) liquid transfer pumps at

radionuclides are discussed In Section 4.4.2.1.) As shown In Figure 0\.5, the process consists of chemical
addition, filtration through a 0.1 I/ff1 filter, solids recirculation, solids separation and dewatering, and final
neutralization. M dl8cussed In more detai in Section 4.4.2.1, chemical addition is a pretreatment step for
f;
initiating precipitation, co-preclpltatlon, and adsorption of metals, I.e., conversion to the solid phase. However,
the solids will aid in the removal of Influent suspended solids by coagulation of fine particles and/or
enmeshment In the hydrous metal oxide ftoes. The pretreated feed combines with the recycle stream (2 to 5
."
percent solids) from the membrane filtration unit and Is subsequently filtered mechanically. The membrane filter
Is in a shell and tube configuration with the membrane on the Inside of the tubes. The permeate passes
-
through the tubes perpendicular to the main ftow at a low operating pressure. The ftux through the filter Is high
relative to other membrane technologies, e.g., reverse osmosis and ultrafiltration, because of the large pore
diameter of the titer. Flux rates of 200 to 400 gallons per square foot per day (gaI/tt2 /d) are typical for the
membrane. A fraction of the recycle slurry Is bled off for solids removal through gravity separation and
mechanical dewatering. The permeate (ftow passing through the filter) Is neutralized by addition of sutfuric acid
prior to discharge.
For the surface water 1M/IRA. It Is assumed for costing purposes that a modular and skld-mounted unit
will be required, with an assumed output capacity of 40 to eo gpm and approximately 40 kAowatts (KW) of
power. The unit would contain the following components:
. 2 12OO-ga11on reaction tanks;
- 1 ~ 0QrM:n411idon tank;
. 1 7~ recircUatJon pump
. 1 cleaning syIt8m; and
- 28 tubular membrane filtration modules.
Auxiliary tanks and process equipment would Include:

Effectiveness
.
Cross-flow membrane titration Is effective at removal of suspended solids. There are numerous
applications of this technology In use throughout the United States. Effluent suspended solids concentrations

are less than 1 mg/ I (nepe! and Shorr. 1985). Because the radionuclldes and metals are largely associated
with the suspended solid fraction (see Section 4.4.2.1). simple suspended solids removal Is anticipated to
remove greater than 99 percent of these constituents. Toxicity of contaminated surface waters is thus
significantly reduced In terms of potential future radlonuclldes and metals exposure. and It is likely that the
ARARs will be achieved with the proper chemical feed. Treated water will be monitored to ensure contaminants
are within regutatory guidelines. Cross-flow membrane filtration provides reliable and automated surface water
treatment service requiring minimal operator intervention. Workers can be easny trained on the safe operation
of the unit and handling of dewatered solids. This. together with health and safety design considerations (trailer
venting, alarm/emergency shutdown systems. automated clean-in-place equipment. etc.) provides a high
degree of worker protection. Sludges generated by the cross-flow membrane titration process wUI be handled
according to the RFP standard waste management procedures and project-specific SOPs.
I mDiernentabAItV-
Cross-flow membrane filtration as described above has been used in industry and municipalities for
wastewater treatment and for ground-water and surface water remediation since 1979. There are hundreds
of units in operation today demonstrating that cross-flow membrane fUtratlon Is a reliable process. The high
solids content of the recycle flow produces scour action on the membrane. minimizing fouling and thus the
cleaning frequency (1 hour fNery 40 to 80 hours of operation). The membrane, an inert fluorocarbon material.
can be cleaned with strong oxidants (hypochlorite) to remove bacterial films. or strong acids or bases to

The demonstrated performance and anticipated effectiveness for remediating au 2 surface waters
collected from South Walnut Creek Basin should result in a high degree of public acceptance of cross-flow
membrane filtration.

Assumed capital and operational costs for the cross-flow membrane filtration system are shown in
Table 4-7. Note that since the economic analysis of the treatment alternatives is a comparative one, process
stream monitoring and analysis costs are not included in the cost estimate for cross.flow membrane filtration
or other treatment units examined in this section since these costs are common to all treatment units. In
calculating sludge disposal costs, values for influent suspended solids concentration (350 ppm) and average
annual year-round influent flow (20 gpm) were estimated. The influent suspended solids concentration is
based on a flow-weighted average concentration calculation similar to that used for calculating the influent
contaminant concentrations in Table 4-1. The suspended solids concentration data used in the computation
was obtained from the 1987, 1988 and 1989 field investigations. The average year-round influent flow of
20 gpm is estimated in Section 4.3.1.1. A cross-flow membrane filtration system can be installed for $486,500.
with annual operation and maintenance costs of $249.000 per year. Assuming a 10 percent interest rate and
a 3O-year operating life, the present worth of the system is $2.833.500.

4.4.1.2 Granular Media Filtration
OescrlDtIon
Y'
The continuous backwash, continuous upflow sand flter was Introduced to the United States in 1979
(Hetzer, 1987). As shown In Figure ~, polymer is Injected into the surface water, followed by rapid mixing
'.
in an IrHine static mixer. Water rises through the bed where flocculation, coagulation and floc removal occur.
Oean water overflows a weir at the top of the sand bed. As the water rises, sand moves downward through
the bed Countercurrent to this flow of water. This downward motion Is Induced by an air 11ft system In the
center of the bed (centralized pipe with air injection at the base) that draws the sand upward. Turbulent flow
is created In this air 11ft, scouring the dirt from the sand. The dirt/sand slurry spills over at the top of the alrtlft
Into a compartment with a perforated bottom and overflo.w weir. The rapidly setUlng sand separates from the
dirt in this compartment, and the clean sand is returned to the top of the sand bed. The dirty water exiting the
filter would be directed to a sedimentation tank, and the overflow from this tank sent back to the filter. The
solids from this tank will require dewatering and disposal waste management operating procedures.
Continuous upflow sand filters are typically designed based on a hydraulic loading of 4-5 gpm/tt2. For the
surface water 1M/IRA. a packaged fiberglass unit with filtration area of 12 tt2, a diameter of 4 feet, a height of
12 feet with a sand bed depth of 40 Inches (3.3 tons of sand), and requiring 0.5 to 1.5 standard cubic feet per
minute (SCFM) of air at 15 to 25 pounds per square Inch (psi) would be applicable. A 10,OOO-gallon settling
tank as well as a sludge conditioning and dewatering system will also be required.
Effectiveness
Granular rnedla filtration with polymer addition is as effective at removal of suspended solids as
conventional floccuatlon/coagulation and rapid sand filtration. Plutonium, americium, metals and, to a lesser
extent, uranium will be largely removed In this unit because plutonium and americium exist predominantly as
colloids in natural waters (Ortandinl, 1990). The unit operation equipment Is simple In design, offers operational
reliabUity, and requires no special skUls for installation. Workers can be easUy trained on the safe operation

provides a high degree of worker protection. The effluent from this system will be suitable for subsequent

..
Imclementabilitv
.
Granular media filtration with polymer addition Is a demonstrated technology with regard to suspended
solids removal. Continuous upflow sand filters are particularty suitable for small water treatment plants where
operating personnel are limited. They operate continually without the need to be shut down for backwashlng
because they are self-cleaning and have no moving parts. The unit operation equipment required (i.e.,
continuous upflow filter, in-line static mixers, filter press, etc.) are standard and readily available. The upflow
filter with continuous backwash is available as a complete unit and a minimal amount of structural mounting
and piping is required to place it into service. Off-site permitted disposal facUlties are available for disposal of
treatment residuals. The demonstrated performance and anticipated effectiveness and reliability of granular
media filtration should result in acceptance of the technology by the public.
~
Relative to conventional suspended solids removal, granular media filtration with polymer addition is
cost effective in terms of both capital and operating expenses. Assumed capital and operational costs for the
continuous upflow sand filter and appurtenances are shown in Table 4-8. The system can be installed for
$167,100, with annual operation and maintenance costs of $82,700 per year. Assuming a 10 percent interest
rate and 3D-year operating life, the present worth of the system is $946,700.

4.4.2 Radionuclldes and Metals Removal
4.4.2.1 Cross-Fiow Membrane FIltration
,.
DescriDtion
.
The cross-flow membrane titration system (as applied to suspended solids removal) was previously
discussed in Section 4.4.1.1. In this section the chemistry and removal mechanisms for radionuclides and
metals. as applied to cross.flow membrane filtration, are discussed.
There are five oxidation states of plutonium (Pu) in aqueous solutions: Pu(III), Pu(IV), PuM. Pu(V1), and
Pu(VII). However, under the oxidizing and near-neutral conditions expected in the surface water. the Pu(lV)
oxidation state Is the most stable (Cleveland, 1979). Pu(lV) is practically insoluble under these conditions
because it readRy hydrolyzes to form Pu(OH)4(s) and. upon loss of water, to produce the thermodynamically
stable PuOz(s). This solid phase Is a colloidal polymer of neutral or positive charge. Increasing pH tends to
reduce the charge density of the polymer. and at pHs above 9 It Is presumed that the colloid becomes
negatively charged. This reduction in charge density and eventual conversion to an anionic form at pHs above
9 decreases Its adsorption affinity for soils and thus increases Its mobUIty in the soil/water environment. In
solution. PuM and Pu(V1) coexist as Ions with the Pu(lV) polymer. At a pH of 8. the dominant ionic form of
plutonium may be PuOzCO:sOH" occurring at a concentration of approximately 10.1ZM (1.5 x 10-6 pCl! 1).
However, the sclubiity c1 plutonium can be increased through complexation with humic acids.
Americium (Am) has one oxidation state in aqueous solutions: Am (III). Under oxidizing and near-
neutral conditions expected in surface water, Am (III) strongly complexes with colloidal material a~ should
exist in the particulate fraction (Orlandini. 1990).
There are four oxidation states of uranium In aqueous solutions: UQII). U(IV), UM, and U(VI) (Sorg.
1987). U(III) and UM are unstable. and U(VI) is the thermodynamically predicted oxidation state of uranium

under oxidizing conditions. U(VI) predominantly exists as the uranyl ion (U022+). The uranyl ion readily
.
complexes with the common anions chloride, sutfate, nitrate, and carbonate. In water with carbonate alkalinity
and a pH range of 7-10, the dominant soluble species of U(VI) are U02(COJ22- and U02(COJt. At pH
exceeding 9.5, the uranium hydroxide complex (U02MOH), + becomes predominant. Unlike plutonium,
~
uranium is signlficandy more soluble in water.
Soluble plutonium, americium, uranium and metals are removed from solution In the cross-flow
membrane filtration process by adsorption on a ferric hydroxide floc. The most effective removal of uranium
by conventional coagulation using Iron salts is at a pH greater than 9.5. This Is presumed to be due to the
predominance of the positively charged uranium hydroxide Ion In the presence of the negatively charged ferric
hydroxide (Sorg, 1987). Because the predomir\8nt form of plutonium and most metals in the surface water is
particulate, the cross-flow membrane filtration process will remove this radionuclide from the influent through
adsorption to, and enmeshment in, the ferric hydroxide.
Ferric sutfate [F~(SOJJ Is the iron salt of choice for introducing ferric Iron to the Influent stream.
Because of the hydrolysis of ferric iron, the pH drops to 2 or 3, which facDitates dissolution of the iron sail The
ferric sUfate is automatically fed in dry form to the Influent In reaction tank NO.1 (see Figure 4-5). The ferric
ion will rapidly hydrolyze at high pH (9 to 11) to form ferric hydroxide Fe(OH)3(s). Hydrated lime [Ca(OH)J
is automatically added in reaction tank No.2, and is used to raise the pH, which also improves the
compresslbllty of the ferric hydroxide sludge. In surface water treatment applications, iron and lime
consumption Is typically 0.3 Ibs and 1 Ib, respectively, per 1,000 gallons of Influent. These estimates will be
made more exact based on the bench and flefd-scale treatab81ty studies described in Section 6. An adjustment
with a pH controller wli be required prior to discharge of the permeate to maintain the effluent in a pH range
of 6 to 9.

Although limited. there is data demonstrating the removal of plutonium from water using cross-flow
membrane filtration. The only data avaUabie Is from a study performed at the RFP using a small-scale. cross-

The plutonium removal efficiency indicated by these test results is greater than 99 percent. Other data
from previous test runs on laundry waste water indicated effluent plutonium concentrations less than the
detection limit (0.1 pel/I). Considering the complexing agents present in laundry water, It is possible that the
cross..ftC7tY membrane titration process can meet the MAR for plutonium of 0.05 pCi/ I. Using the percent
plutonium removal for the above reported test and the expected influent concentration of plutonium to the
treatment facUlty, the MAR wli be achieved based on theoretical calculations.
Data demonstrating removal of americium from natural waters is not available at the time of this writing.
HC7tYever, amer1clum's'StrOng affinity for particWites in natural waters suggests that americium should be
removed from South Walnut Creek Basin surface waters by cross..ftC7tY membrane filtration via the suspended
solids removal mechanisms. This observation is supported by examination of the dissolved and total
americium concentrations detected in South Walnut Creek Basin surface water samples (Appendix B).
Examination of these data reveals that there were no instances where dissolved americium concentrations
exceeded the ARAR. Total americium concentrations (i.e., dissolved plus particulate). however, exceeded the
ARAR on several occasions.

Because of its ubiquity in water supplies, there is considerably more Information on the removal of
uranium during water treatment.
Uranium removal efficiencies have been reported for conventional
~
coagulation/filtration water treatment, and data exist for cross-flow membrane filtration used at the RFP and
at Uranium Mill Tailings Remedial Action (UMTRA) sites. The UMTRA project is a DOE-sponsored program to
clean up low-level radioactive uranium mill tailings and associated contaminated surface water runoff In eleven
~
western states and Pennsylvania. With regard to conventional water treatment, using a dose of 10 mg/1 of
ferric sulfate as a coagulant with a pH of 10, 80 percent removal of uranium has been reported (Sorg, 1987).
Use of ferrous sulfate at doses between 20 to 25 mg/1 and at the same pH resulted in removals as high as
92 to 93 Percent. For cross-flow membrane filtration, the above-reported test at the RFP Indicates achieving
greater than 99 percent removal and meeting the ARAR for uranium (10 pCI/1). At the Canonsburg UMTRA
site, water containing 4,400 pCif 1 of total uranium was treated to achieve a total uranium concentration of less
than 1 pCi/1. Although specific data is unavailable, the cross-flow membrane filtration unit operating at the
Durango UMTRA site is achieving effluent uranium concentrations below the Colorado in-stream standards for
that area.
It would appear that cross-flow membrane filtration should be effective for removal of plutonium,
americium and uranium as well as other metals from South Walnut Creek Basin surface water. ARARs should
be achieved for plutonium, americium and uranium, although there is less data and correspondingly less
certainty on the performance of the system for plutonium and americium removal. ARARs for gross alpha and
gross beta should also be achieved. The gross alpha is largely from uranium and particulate forms of
plutonium and americium, and most of the gross beta arises from uranium 238 daughters, e.g., thorium 243
and protactinium 234. The thorium and protactinium predominantly exist in the particulate fraction and should
be removed by cross-flow membrane filtration via adsorption on iron hydroxide. Although cesium 137,
potassium 40, lead 210, and strontium 90 (which are more soluble) also contribute to gross beta activity, the
success of the current filtration operation to lower the gross beta concentration at Pond B-5 would indicate
that they are not significant contributors to the gross beta activity in South Walnut Creek. Removal of the
radionuclides should effectively reduce the potential threat to the public health and the environment. The ARAR
for TDS may not be achieved with cr9SS-fiow membrane filtration as a result of the addition of ferric sulfate and
lime to the process influent.

4.4.2.2 Ion Exchange
DescriDtlon
The ion exchange treatment system for the removal of radionuclides consists of a strong base anion
exchanger followed by a weak acid cation exchanger (Figure 4-7). These exchangers are designed for the
removal of uranium and plUtonium/americium, respectively. Both Ion exchangers have been designed
conservatively using a hydraulic loading less than 5 gpm/tt2 and a bed capacity less than 2 gpm/ff. This
translates to a 4-foot diameter column with a resin bed depth of 3 feet. The column wUI include 100 percent
freeboard. This freeboard Is necessary for resin expansion during regeneration or for backwashlng If required.
The strong base anion exchanger wUl contain 37.5 ff of Rohm and Haas IRA-402 resin or equivalent
in the chloride form. Regeneration wDl not be required because of the high affinity and capacity of the resin

other anions in solution will, over time. displace these anions. The spent resin wUI uttimately require

The cation exchanger will contain 37.5 ft' d Rohm and Haas IRC-SO weak acid cation exchange resin
or equivalent in the sodium form. This resin has a high affinity for high molecular weight metals. e.g., mercury.
copper. lead. and zinc. Published Information on the removal of plutonium and americium from natural waters
by Ion exchange has not been found. A cation exchange resin with a high affinity for heavy metals is most
likely to remove plutonium and americium because these constituents will predominantly exist as colloids
carrying a positive charge. The performance of Ion exchange for the removal of plutonium and americium is
unknown; however, It is noted that most of the plutonium and americium should be removed during upstrEN}m
suspended solids removal. There is Insufficient Information to determine the frequency at which the resin wDl
require regeneration. It Is assumed that. like the anion exchanger, the cation exchanger will not require
regeneration over the life d the 1M/IRA.
Effectiveness
Ion exchange has been proven to remove heavy metals and uranium from water to meet the ARARs.
whereas plutonium and americium removal using this technology Is unproven. Ion exchange has been used
to remove uranium from mine water for many years and has been studied extensively by EPA for the removal
of uranium from drinking water (Sorg, 1987). Ion exchange is commonly used for the removal of plutonium
from strong acid solutions, but no information exists on the use of ion exchange for the removal of plutonium
(or americium) present In natural waters. The absence of plutonium and americium removal efficiencies in Ion
exchange does not allow conclusions to be drawn with regard to its effectiveness in reducing the toxicity of
influent South Walnut Creek Basin surface waters. and thus, protection of human health and the environment
and public health.

An Ion exchange system Is for the most part a self-contained and automated operation. Workers may
be easily trained on the safe operation of the system. There Is uncertainty as to whether the cation exchanger
"
(I.e., plutonium and americium removal) will require regeneration. This lends uncertainty as to the volume of
treatment residuals that will be generated as well as the degree of worker exposure in handling the
.
regeneration wastes. The anion exchanger will not require regeneration, as discussed eanier, as the uranium
carbonate complex wli preferentially displace major ions that wil initially load onto the resin.
ImciementabRItv
Ion exchange Is a well established technology that has demonstrated long-term reilabUIty and
performance In water treatment and after applications. The vessels, piping and pumps required to construct
a system are commercially available, off-the-sheff Items. The anion and cation exchange resins, however, are
specific to each application and, as suggested above, effective resins for plutonium and americium removal
from surface waters may not be readly avaIabie. If the weak acid cation exchanger requires regeneration (i.e.,
plutonium and americium removal), an acid regeneration system would be required, and the wastewater from
regeneration would require storage and treatment at the BuDding 374 Process Waste Treatment System
(chemical precipitation/flash evaporation). If regeneration of the cation exchange resin Is not required.
operation and maintenance requirements for the system wli be low. Effluent would be routinely monitored for
breakthrough of the radionuclldes shown in Table 4-1. The removal of suspended solids in a pretreatment step
Is required to prevent foUlng of the resin.
At th~ ~, the degree of uncenainty associated wtth plutonium and americium removal suggests the
public wli not readlyaccept Ion exchange as a preferred treatment technology. Demonstration of technical
feaslbllty through treatabDIty study testing Is necessary.

GAC adsorption systems have been shown to remove VOCs from contaminated water to levels that
comply with the ARMs. The EPA (Federal Register. Va. 52. No. 130. page 25698) has designated carbon
..
adsorption a "Best Avaiable Technology" for the removal of seven specific VOCs from drinking water which
includes common chlorinated solvents. This assumes that vinyl chloride, methylene chloride, and acetone are
not present at the proposed South Walnut Creek Basin surface water collection locations since these
compounds are not readly adsorbed from solution using activated carbon. The surface water quality data
presented In Appendix B Indicates that these compounds were detected at levels above ARARs only at stations
SW-56. SW-«> and SW-101. It is proposed, however, that surface water from these stations be collected at
the downstream station SW~1 where vinyl chloride, methylene chloride and acetone have always been
estimated below detection limits and/or were also present in the associated laboratory blanks. The absence
of these VOCs at SW~1 may be due to laboratory artifact Q.e., not actually present at the upstream stations),
dUution. and/or voladlzatlon.
The probabUlty of equipment faDure wUI be minimized in this system because of the redundancy of
having standby lead and polishing adsorption units In parallel to the operating units, each of which could treat
the design flow. Two additional stock units on site add to the system reliabDIty. Appropriate safety measures
required when moving and Installing large equipment will be complied with during installation. The operation
and maintenance of the system wli be by personnel who are trained in the handling of hazardous and
radioactive wastes. Wet activated carbon preferentially removes oxygen from the air. Therefore, any time
personnel are working In confined areas where oxygen may be depleted. appropriate sampling and work
procedures for potentially low~gen spaces will be falowed, Including all applicable federal and state
requirements.
The operators of the GAC system will not be exposed to VOc-laden carbon because the use of the
containerized and transportable carbon contactors allows removal and regeneration/replacement 01 the
exhausted carbon at a remote carbon reactivation site. Carbon wUl not be handled at the site. Transporting

carbon. and the operators need only follow routine safety procedures which are appropriate to handling heavy
equipment.
,
The exhausted carbon Is generally regenerated through a thermal treatment process which strips the
volatile organics from the carbon. The organics are subsequenUy destroyed via incineration. During this
,.
regeneration process, a small quantity of ash may be generated which requires disposal at a landfill. Thus.
this process can be considered an alternative to land disposal since the carbon Is continuously recycled.
GAC adsorption treatment In sealed. ftxed-bed contactor vessels does not produce any waste streams
or vapor emissions. The safety of nearby communities should not be adversely affected and the risk of harm
to the environment should not be Increased. This treatment process will effectively remove many of the target
organic contaminants from the surface water. Treated water will be monitored at the effluent and also at an
intermediate point In the system to ensure contaminants are below the MAR .concentratlons before being
released to South Walnut Creek during Implementation of the process.
ImDlementabllltv
GAC adsorption Is a proven technology for reducing many VOCs from water. Testing performed by
Calgon (Rockwellintematlonal, 1988b) demonstrated that activated carbon can remove VOCs to meet ARARs.
A second carbon unit connected In series with the lead unit would serve as a polishing unit and will ensure
removal of the vOCa to these levels. The removat of suspended solids in a pretreatment step is required to
prevent fouling of the carbon. The carbon columns can be easUy shipped and readDy Installed. The system
should be ready to operate.at full capacity after initial adjustments and test runs. Carbon services that provide
rental and regeneration of carbon columns are common and offer an alternative to a capital purchase. A high
degree of public acceptance Is anticipated for GAC adsorption based on Its BDA T classification. and the
minimal generation of treatment residuals. These services are readily available and cost effective for an interim
action.

on breakthrough of 1.1-DCA. This assumes that vinyt chloride, methytene chloride. and acetone are not

present at SW~1. Based on a maximum flow rate of 60 gpm, the annual consumption of carbon will be
approximately 20,000 pounds. The cost of a 2O.ooo-pounds-per-year carbon service Is $50.000. This includes
the rental and regeneration of 10 carbon columns. each containing 2.000 pounds of acttvated carbon. The cost
of round-trip shipping Is estimated at $3.000 per column. It is assumed that the exhausted carbon columns
will be shipped as a manifested hazardous waste.
Using the preceding infonnation. the assumed capital cost for installing a carbon adsorption system
is $70.600. and the assumed annual operating cost Is $170.300 as shown in Table 4-10. Costs for pretreatment

Effectiveness
..
The UV jperoxide system is capable of removing VOCs from the surface water to levels below the
ARARs. A technology evaluation of a demonstration unit was conducted by the EPA's Risk Reduction
Laboratory in Cincinnati, Ohio (EPA, 1990a). Ground-water treatment experiments were performed In which
residence time, ozone and hydrogen peroxide dosages, radiation intensity and influent pH were altered to
evaluate the technology. The demonstration unit achieved VOC removals greater than 90 percent. These
results indicate that the UV jperoxide treatment process is likely capable of achieving the effluent criteria for
all of the volatile organics listed in Table 4-1. However, the volatile organics may not be completely oxidized
to carbon dioxide, water, and chloride, and unintended organic degradation products may be produced.
The system requires periodic UV lamp replacement and routine maintenance, and with such
maintenance, the unit expected to have long-term reliability. The risk of failure of the system at any time is
highly unlikely. However, because surface water is expected to have widely varying concentrations of
organics,it will be difficult to ensure adequate peroxide dosage for complete organic destruction and to prevent
the appearance of excess peroxide in the effluent. While the presence of ferrous iron and manganese can
impede the effectiveness of the UV jperoxide treatment system due to the precipitation of these metals, a
manufacturer has indicated that this will not be a problem at the iron and manganese concentrations expected.
However, should precipitation problems arise, appropriate pre-treatment and post-treatment will be
implemented to correct this problem.
The UV jperoxide oxidation system will destroy VOCs present in contaminated South Walnut Creek
Basin surface water and thus represents an alternative to land disposal. The system Itself will not produce
treatment residuals. Some support unit operations (i.e., pre-treatment) for the UV jperoxide oxidation system,
however, may require residual waste management.

imDlementabBltv
UV /peroxide oxidation Is a technology for the complete destruction and detoxification of hazardous
organic compounds in aqueous solutions. Although the technology is relatively new and has had limited
application in the field, SARA requires EPA to prefer remedial actions that significantly and permanently reduce
the toxicity. mobIlty, or volume d hazardous wastes by employing innovative technologies that result in the
destruction or detoxification d the wastes. The equipment necessary to construct a UV Peroxide system is
not "off-the-sheIt', but must be designed for each individual application. The equipment components and
materials necessary to construct a system are readDy available, however.
Demonstrated performance of the UV /peroxlde ground-water treatment system has been somewhat
limited due to the relatively new development of the process. However, there are six UV /peroxlde units
currently operational or orHine and ready for operation. One of these units is located at Rocketdyne's
Santa Susana facUlty in southern California. POot-scale operations were performed on ground water containing
VOCs (TCA, TCE. etc.) at system flow rates of approximately 20 to 40 gpm. Results from the pilot scale testing
were favorable, and a UV /peroxide ground-water treatment unit has been purchased, set up, and site tested.

Another UV jperoxlde ground-water treatment system, located locally, was visited and appeared to be a low-

.
concentrations significantly lower than those found at the 881 HUlside (approximately 7 ppb). However, the
same UV treatment process had Initially and effectively treated ground water with much higher concentrations.
....
Operating and maintenance requirements for the UV jperoxide treatment system are relatively minor.
The system wli require up to 500 kW of power, a high electrical power consumption requir~nt relative to
other treatment processes, and 12,200 poundsjyear of 50 percent ~02 solution for normal operation. Routine
maintenance of the equipment Is required and the UV lamps wli require replacement approximately fNery six
months. All four system UV lamps can be exchanged In about an hour. Influent pretreatment for suspended
solids removal Is required to prevent fouling of the oxidation chamber. Also, Influent pre- and post-treatment
for removal of Iron and manganese may be necessary as discussed above. The system wUl require careJul
observation to ensUre the system Is operating property, although system alarms will notify operators If a
problem does occur.
Public acceptance of UV jperoxlde oxidation should be favorable based on removal efficiencies
observed to date. The attribute of mineralizing VOCs present in surface water ~.e., converting them to carbon
dioxide and water) shoUd also receive a favorable response. TreatabUlty testing on contaminated South

technology.

4.4.3.3 Air Stripping with Off-Gas Treatment
'"
OescriDtlon
O~ring air stripping, VOCs are transferred from.the water to a continuously flowing airstream which is
in direct contact with the water (Figure 4-10). Influent contaminated surface water wll enter the top of a 32-
inch diameter, 34-foot air stripping column and subsequenUy contact clean air supplied through the bottom
of the column (column sizes are approximate). Appropriate air-to-water flow rates WIll be utRlzed to provide
for the optimum (99 + percent) transfer of the contaminants from the surface water to the air stream. The
treated surface water will then be pumped through a 2000-pound liquid phase carbon treatment polishing unit
(identical to the one described In Section 4.4.3.1). The air stripper emissions wUI be heated above dew point
and then passed through a vapor phase carbon system to remove the organics before being released to the
environment. The vapor Phase carbon unit will contain 2,000 pounds of carbon.
Effectiveness
The use of an air stripper Is a highly effective method of removing hazardous VOCs from water. The
efficiency of . the proceSs Is well documented. The Environmental Protection Agency (Federal Register,
Vol. 52, NO.1 30, page 25698) has designated packed tower aeration along with granular activated carbon, as
a BOAT for the removal of VOCs from drinking water.
An air stripper coupled with IIquld- and vapor-phase carbon adsorption Is a proven system that has a
dependable record of use. It is expected that this treatment process, with proper maintenance, wUI provide
the desired level of contaminant removal to meet the ARARs.

be considered an alternative to land disposal since the carbon is continuously recycled. However, if the spent
liquid-phase carbon is determined to be a mixed waste. then it would require land disposal at a facility
permitted to accept mixed wastes. The vapor-phase carbon adsorption system will remove the organics from
the air stripper emissions before being released to the environment. Therefore. the vapor-phase carbon
adsorption system will eliminate the impact of any air stripper emissions on the public health. The safety of
nearby communities should not be adversely affected and the risk of harm to the environment should not be
increased. Treated water and air will be monitored to ensure that contaminant levels are below ARARs.

The air stripper wil remove greater than 99 percent of the contaminants in the surface water. Because
the air stripper performance Is sensitive to changes in flow and contaminant concentrations, a liquid-phase
...
carbon adsorption unit Is in series with the air stripper to enhance system performance and to ensure that the
treated effluent meets MARs for VOCS. Based on a ftow rate of 60 gpm, 24 hours per day, liquid phase
carbon usage wil be approximately 11 pounds/day, and each 2OOO-pound carbon unit will require replacement
approximately fNery sbc months. Vapor phase carbon usage will be approximately 10 pounds/day, and each
2000-pound carbon unit will require replacement approximately fNery six months.
Operation of the treatment process Is relatively simple, requiring occasional cleaning of the air stripping
column and replacement of carbon. The air stripper will require cleaning to remove scale buUdup on t~e
packing material In order to maintain optimum removal efficiency. Effluent from the cleaning operation Will
require treatment in the BuDding 374 Process Waste Treatment System. The removal of suspended solids in
a pretreatment step Is required to prfNent fouling of the carbon and liquid phase adsorber. Transportation and
regeneration of the Ilquld-phase and vapor-phase carbon units at a remote carbon reactivation site wUl be
required. The air stripping with off-gas treatment system for remediating VOC-contaminated surface water is
avalable commercially and could be implemented quicldy. No difficulties are anticipated during the installation
and startup of this treatment system.
Air stripping with liquid and vapor-phase GAC adsorption should receive a high degree of public
acceptance due to Its proven track record and classification as a BOAT.

Assumed costs for the air stripping ground-water treatment system are shown in Table 4-12. Costs for
pretreatment of the Influent for removal of suspended solids are not considered In Table 4-12. The total capital

COMPARATIVE ANALYSIS
,
..
5.1
INTRODUCTION
This section summarizes the evaluated surface water collection and treatment technologies, and
presents a tabular comparison of the evaluation resutts (Table 5-1). A recommendation is made for a preferred
surface water 1M/IRA using the comparative analysis.
5.2
COMPARISON OF TECHNOLOGIES
Collection of surface water by diversion at the sources was established in Section 4 as the only
reasonable alternative for collection of contaminated South Walnut Creek Basin surface waters in au 2 and
is. therefore. the preferred collection technique for the 1M/IRA. On the other hand. several technologies for
surface water treatment were considered.
These technologies include chemical treatment/cross-flow
membrane filtration ("cross-flow membrane filtration' is used for brevity) and granular media filtration with
polymer addition for suspended solids removal: cross-ftow membrane fUtration and ion exchange for
radionucllde and metals removal; and GAC, UV /peroxlde oxidation and air stripping with liquid- and vapor-
phase GAC for vac removal.
The cross-ftCM' membrane titration technology is the preferred method for removal of radionuclides and
metals because It Is the most likely treatment technology that wUl remove these constituents from the South
Walnut Creek BasIn surface water and generate an effluent that Is protective of public health and the
environment. This is a result of adsorption of radlonuclides and metals on a ferric hydroxide floc as described
in Section 4.4.2. It is noted that cross-ftow membrane filtration and granular media filtration with polymer
addition are both effective technologies for removal of suspended solids. However. because cross-flow
membrane filtration Is the preferred technology for radionuclide and metal removal. additional surface water

~C is the treatment technology of choice for removal of VOCs. GAC is a proven technology that is
reliable, easy to operate, and the most cost effective of the three technologies examined. This technology is
not suitable for removal of vinyl chloride, methylene chloride, or acetone. However. as discussed in Section
4, these constituents are not expected, in the Influent to the treatment system, above their respective ARAR
levels. In the event that the field-scale treatabHity study indicates that vinyl chloride, methylene chlorid~ or
acetone are present at concentration levels not appropriate for liquid-phase GAC adsorption, modifications to
or replacement d the liquid-phase GAC system will be considered at that time. Although UV /peroxide can
oxidiZe all of these contaminants. effective operation is likely to be difficult with changing organic loadings from
a surface water system Q.e., process control). In addition, UV /peroxlde Is substantially more costly to install
and operate than the other organic removal technologies. Air stripping is a viable VOC treatment technology
for the South Walnut Creek Basin Surface Water 1M/IRA This process, however. is much more complex by
design than liquid-phase GAC, which makes it more difficult to operate and has a higher probability of system
downtime. Finally, the cost of air stripping with liquid and vapor-phase adsorption is roughly equal to that for
IIquid-phase GAC.
Radionudldes and metals wUI be removed upstream of the GAC unit. The GAC should. therefore. not
become a mixed waste and will be suitable for regeneration at any facUity that accepts spent carbon for
regeneration. This will provide for the ultimate destruction of the contaminants consistent with guidance in the
NCP. which requires consideration of remedial alternatives that include an alternative that removes or destroys
hazardous substances.

SECTION 6
PROPOSED 1M/IRA
6.1
SUMMARY
The preferred South Walnut Creek Basin Surface Water 1M/IRA consists of the following components:
.1.
Surface water collection by diversion at the sources; and
2.
Treatment of surface water by chemical treatment/cross-flow membrane filtration ("cross-flow
membrane filtration" is used for brevity) followed by liquid-phase GAC treatment.
6.1.1
Surface Water Collection
Figure 4-3 shows the locations of the surface water diversion and collection systems proposed in this
alternative. The collection systems are denoted CS-59. CS~1, and CS-132. Collected surface water is
automatically transferred to the treatment system by pipeline.
Flows at stations SW-56, SW-«>, SW-101, and SW-133 will be collected at the downsteam station SW-
61 by a new surface water diversion weir and pump station. The weir will serve to divert up to 37.5 gpm (14
gpm average annual withdrawal rate) from the drainage. Contaminated surface water will be diverted upstream
of the weir into a 1 LOOO:-gaJlon precast concrete sump provided with a screen, where large debris is separated
from the flow. This screen wil require manual cleaning to remove debris. Water will be pumped from the
manhole to the treatment facUlty. When the Inflow into the sump exceeds the pumping rate. the excess flow
wUl return through overflow piping to the drainage below the weir.
The seep flow from SW-59 will be Isolated from the South Walnut Creek drainage and collected
separately from CS~1 using a SOO-gaJlon. precast concrete sump. The sump and installed pump will be
designed to collect and transfer the design flow of 4.5 gpm (1 gpm average annual withdrawal rate). Flows
SURFACE WATER INTERIM RENECIAl AC'T1ON PI.AN
ROCI
-------
in excess of 4.5 gpm wm be discharged to South Walnut Creek, via an overflow pipe, to the drainage. The
overflow will enter South Walnut Creek upgradient of CS~1 and wUl either be collected by or allowed to pass
CS~1, depending on whether the creek flow is less than or greater than the 37.5 gpm design flow for CS-61.
Upper South Walnut Creek flow wli be collected at SW-132 by a new surface water diversion weir and pump
,,'
station. The weir wli serve to divert up to 18 gpm (5 gpm average annual withdrawal rate) from the drainage.
.
Contaminated water will be diverted into a 1000-gallon precast concrete sump. Flow in excess of the design
flow (18 gpm) will be permitted to overflow the diversion weir.
The design flow and annual average withdrawal rates for the South Walnut Creek drainage (i.e., CS-59.
CS~1, and C5-132) are 60 gpm and 20 gpm, respectively. It is proposed that all surface waters collected and
treated in this 1M/IRA wUl be discharged to South Walnut Creek, just downgradient of CS-132.
6.1.2
Surface Water Treatment
The surface water collected will be treated using cross-flow membrane filtration (for suspended solids
and radionuclide removal), followed by liquid-phase activated carbon (for organics removal) (Figure 6-1). The
respective units and appurtenances wUI be housed in three 48-foot traDers to protect weather- or temperature-
sensitive components. Fire protection within the traDers will be provided by two wall-mounted, 25-pound, dry
chemlcal-type fire extinguishers. The traDers and all treatment units are constructed of non.:combustibles.
Other than minimal files and records. no combustible materials wAI be maintained within the trailers. Extemal
water pipes wUI be above ground and heat traced to protect against freezing. All tanks, piping and sumps will
be equipped with secondary containment to comply with 6 CCR 1007-3 and 40 CFR 264.193.

of equalization detention time. The average annual influent flow rate. however. is estimated at approximately
20 gpm. Surface water collected during periods of these lower influent flow rates will be allowed to accumulate
in the equalization tank and then treated at the system design flow rates.

The concentration tank will be made of fiberglass reinforced epoxy equipped with appropriate baffles
and liquid level controls. The recirculation pump will be stainless steel for corrosion resistance and rated at
100 feet of head. The pump will be provided with water-flushed double mechanical seals.
..
The treated water will be filtered through tubular (10 diameter) filtration membranes made of
-
fluorocarbon polymer, and arranged in trains of 1 D-tube modules piped in series. supported on accessible
horizontal racks. Each module will be 6-feet long and 7-incheS in diameter, with a separate oUtlet for clean
effluent. ~ flow Indicating and totalizing meter wAI be provided on the effluent line. Manifolds will be provided
to collect the effluent and direct It by gravity to the neutralization system. The metaljradionuclide suspension
will be concentrated to a 2 to 5 percent slurry in the concentration tank, from which it will be periodically
pumped to the slurry holding tank and titer press in the slurry dewatering system. The slurry removal rate will
be adjusted manually to maintain the desired solids concentration in the filtration section. All piping and valyes
in contact with the water being treated will be heavy-duty, corrosion-resistant plastic.
Neutralization Svstem
A skid-mounted neutralization system wUI be provided to adjust the effluent pH to the conditions
required for discharge or recycle. The neutralization system will be sized to receive and treat the effluent from
the membrane filters. The neutralized effluent will leave the system by gravity. The equipment and
components of the neutralization system are as follows:

6.1.2.2 Organic Contaminant Removal
Organic contaminant removal by GAC is a considerably simpler process. After cross-flow membrane
filtration, the surface water will be pumped through two GAC columns in series, operated in downflow fixed-bed
mode (Figure 6-1). Two additional GAC columns wUl be In stock. Each carbon column is 60 inches in
diameter and 87 Inches high and contains 2000 pounds of carbon. Based on a flow rate of 60 gpm, the
hydraulic loading to each column will be approximately 3 gpm/tt2. Empty bed contact time for each colwnn
wUI be approximately 18 minutes. The columns are of stainless steel construction and will be interconnected
by flexible pipe with 2-inch carnlock hose connections. Once the column is drained of water, the unit is a
shipping container for returning the carbon for regeneration.
6.1.2.3 Effluent Discharge
Following treatment, the water wUI continuously discharge to South Walnut Creek just downgradient
of CS-134. Samples wAI be collected and analyzed twice per week. In the unlikely event of off-specification
processing or treatment process faiure, the treatment system discharge wUl at most return the drainage to its
pre-1M/IRA condition. In addition, detention, treatment, and monitoring at Pond B-5 provides a downgradient
safeguard.

. OPERATION AND MAINTENANCE
.
6.2.1
Surface Water Collection
..
The collection systems are reiativeiy maintenance free. Manholes, sumps, and backwater pools will
require periodic cleaning to remove accumulated solids. Pumps will also require routine inspection and
maintenance.
6.2.2
Cross-Row Membrane Filtration
The cross-flow membrane filtration system's instrumentation and controls will monitor and automatically
adjust chemical feed rates. System levei switches wUl automatically operate the feed and process pumps to
allow for the continuous flow of surface water through the system. Interlocks and alarms will automatically shut
down the system If critical components are operating outside the design limits. Therefore, the system will be
capable of processing surface water with only minimal operator attention. However, operator attention required
for the system, estimated at less than two hours per shift. will include these tasks:
1.
Maintaining appropriate solids concentration in the concentration tank by adjusting the amount
of waste slurry feed to the dewatering section;
2.
Replenishing chemicals as needed;
Routine cleaning and calibration of pH or ORP probes; and
3.
4.
Periodically initiating the cleaning cycle and changing the cleaning solution. Typically. a
cleaning cycle takes less than 1 hour and Is carried out once every 40 to 80 hours of system
operation.
The filtration system includes a cleaning loop to provide for rapid convenient in-place cleaning of the
membrane surface. This includes two 500-gallon polypropylene tanks, an all-plastic cleaning pump (5 HP. '00
gpm at 80 teet of head) and appropriate valves and piping so that the periodic cleaning procedure can be
carried out conveniently and quickly. Actual operating experience will determine the cleaning frequency

required for optimum performance of the system. During the cleaning procedure, fresh water is used to flush
the waste slurry from the modules back to the concentration tank, and a cleaning solution (usually a strong
acid) is circulated through the modules with the cleaning pump for a few minutes. Finally, the cleaning solution
J
is flushed from the modules with clean water. Provision is made to reprocess the cleaning solution as part of
the normal waste stream so that only clean effluent leaves the system.
.
6.2.3
Activated Carbon
Operation and maintenance of the GAC system is also relatively simple. To completely utilize the
carbon, the columns will be arranged in series, allowing the lead column to become fully exhausted for
subsequent regeneration while the second (polishing) column ensures effluent quality. Periodic samples will
be taken from the effluent of each unit, and when the lead unit effluent exceeds chemical-specific ARARs, the
lead carbon column will be removed, the polishing (second) column will become the lead column, and a
stock carbon column will be put in service as the polishing unit. This is expected to occur every three weeks.
The carbon column with the exhausted carbon will then be shipped to an off-site location for regeneration.

TREATABIUTY STUDIES
...
A preferred surface water treatment system for the proposed 1M/IRA has been selected in spite of
several informational constraints. First, It is uncertain, although unlikely based on the available data, that
methylene chloride, vinyl chloride, and acetone are present within South Walnut Creek Basin surface waters.
Second, limited treatment technology performance data currently exist for removal of plutonium and americium
from natural waters. This is particularty true in the case of ion exchange. Finally, the physical state of
plutonium and americium (i.e.. dissolved vs. colloidal) In surface waters is not completely understood, nor have
the radlonuclides that contribute to the gross alpha and beta. activity been defined. The selected treatment
system is the logical choice given the avanable surface water quality data. literature information regarding
plutonium and americium chemistry and treatment processes for their removal, and best engineering
judgement.
However, treatability studies are appropriate to confirm the selection of the preferred treatment system
or to provide the basis for selection of an alternative system should the preferred system be judged to not
perform adequately.
The DOE wli conduct bench- and field-scale treatabDIty studies to determine the effectiveness of cross-
flow membrane titration, GAC, Ion exchange and other technologies in treating South Walnut Creek Basin
surface waters. Objectives of the bench-scale study Include determination of applicability of the treatment
technology, quantification of major operating parameters, evaluation of performance relative to meeting
chemical-specific ARARs and reevaluation of capital and operating costs. GAC wi/I be tested using a field
treatment unit which will be deployed in the northwest portion of the East Trenches Areas for treatment of

surface water from stations SW-S9, SW-61, and SW-132. The initial operational unit of the field unit is expected
to be Installed and started up in the Spring 1991. Because this first unit (the GAC system) will be used
primarily to demonstrate organic contaminant removal efficiencies. It will not be expected to attain chemical-

specific ARARs for metals and radionuclides by Itself. Additional units wUl be added over a several month
period to evaluate metals and radionuclides removal. Operation of this field-scale facUity will include testing

and modification of the original equipment as well as the addition of support equipment and/or alternative
troatment elements. A summary report of the treatabHity study findings wUl be submitted to the regulatory
agencies upon completion of the program. The results of these tests and the bench-scale treatability studies
may indicate that It is not practicable to attain all ARARs fOf the Surface Water 1M/IRA. Final performance
requirements for the 1M/IRA will require approval by the regulatory agencies.

SECTION 7
ENVIRONMENTAL EFFECTS OF THE PROPOSED INTERIM REMEDIAL ACTION
tI
The proposed surface water 1M/IRA, and potential subsequent environmental and human health effects'
'.
resulting from this action, are evaluated in this chapter. Environmental impacts to air quality. water quality,
terrestrial features (including wildlife and wetlands). archaeology and historic sites. and short- and long-term
land productlvtty are discussed In SectIons 7.1. 7.2. 7.3. 7.4 and 7.5, respectively. Human heatth exposure risks
from in_lation, routine operations. and accidents are analyzed in detalln Sections 7.6 and 7.7. These
analyses evaluate the risks to workers involved in the 1M/IRA. to other RFP site employees. and to the general
public. The commitment of resources (material/human), transportation impacts and cumulative impacts are
discussed in Sections 7.8 through 7.10.
7.1
AIR QUAUTY
There are three potential air quality impacts associated with the proposed OU 21M/IRA to selectively
collect and treat surface water within the South Walnut Creek Basin OU 2 from surface seeps and surface water
monitoring stations. These are:
1.
Potential VOCs released from exposed contaminated liquids during construction activities (Le.,
sump installation. trench excavation) or at surface water collection, storage, and treatment
locations, as part of nonnaI operations or accident conditions.
2.
Fugitive dusts and fossD fuel consumption related exhausts resulting from activities such as
excavation, construction. operations, maintenance. afld monitoring.
3.
Water treatment process off-gassing released to the environment as part of normal operations
or accident conditions.
Air quality impacts from VOCs released during construction activities (e.g., excavation) will be minimal
when compared to the normal operational activity at the Rocky Rats Plant. The .Phase II RFI/RIFS Workplan"
for OU 2 shows VOCs have been detected in the South Walnut Creek Basin soUs and include acetone (up to
500 ppb), and bis(2-ethylhexyt) phthalate (4,600 ppb) (EG&G, 1990a). Table A-10 in Appendix A presents the

test results for VOCs compied as part of this report. Due to their'isolated occurrence, and the limited amount
of excavation planned, the amount of VOCs released during this construction activity are not likely to cause
measurable changes In the ambient air quality. Based on sample analyses to date, VOC concentrations in soils
~
at South Walnut Creek are Insignificant. Consequently, normal construction activities and excavation for sump
installation, buried pipeline/utUlties and preparation of the pad area for the treatment system may not release
4
VOCs to the atmosphere. Preliminary characterization, based on the Phase I RI Report, indicates the presence
of elevated concentrations of semi-voiatUe organic chemicals (phthalates) In the soil. Any airborne releases

for construction of the South Walnut Creek Basin 1M/IRA at OU 2.
.
Dermal exposure, inhalation, and inadvenent ingestion of airborne radioactivity and VOCs on fugitive
dusts is analyzed in Section 7.6. "Personnel Exposure-Routine Operations", Pollution from engine emissions.
fugitive dust generation by vehicles and particulates from tire wear are analyzed separately in Section 7.9,
"Transportation Impacts".
Collected contaminated surface water will be processed through the proposed cross-flow membrane
filtration system and activated carbon system facUity. Due to the low VOC concentrations in the surface water,
the proposed treatment system will not produce measurable VOC emissions; therefore. no changes in Jhe
levels of these gases in the ambient air off site is expected. The need for periodic membrane cleaning will
require the use of a small amount of sodium hypochlorite (NaOHCI). This could occur once every 2 to 4 weeks
and wUI not impact off-site air quality.
The cross-flow membrane filtration system incorporated into the water treatment system to remove
suspended solids, dissolved metals. and radionuclides may not contribute to emissions during normal
operations or back flushing operations. Mixing of chemicals for water pretreatment or strong acids or bases
used for hardware cleaning operations may contribute to odors within the confines of the water treatment
trailers and should be controlled by adequate ventRatlon, These odors will not be noticeable from outside the
treatment facUlty area. nor will they be a hazard to workers in the traDers under normal circumstances, Spills
of chemicals that might be involved in accident conditions will be administratively controlled by actions
specified In the Operational Safety Analysis (OSA).
The OSA addresses health and safety concerns originating from routine site operations. It is similar
to the SSHSP In that health. safety, and environmental hazards are identified and evaluated for control. This

analysis is also reviewed by and must be approved by the HS Department. Training is required prior to
operation with oversight and monitoring by the HS Department.
.,
Operation and maintenance of the GAC system are simpler than for the cross-flow membrane filtration
system. The GAC columns. containing exhausted carbon. wUl be shipped to an off-site location for
<8
regeneration. Spills of liquids associated with the operation of the GAC columns wUl be limited to the effluent
exiting the cross-flow membrane filtration system. which Will have removed many of the constituents of
concem. The effluent water from the membrane filtration treatment system may contain some amount of
VOCs. Effluent concentration requirements are contained in Table 4-1, Basis for Design of Surface Water
Treatment.
7.2
WATER QUAUTY
The proposed 1M/IRA will reduce the contaminant loading to South Walnut Creek. Surface water runoff
entering excavated areas and exceeding the design capacities of the system may create soil entrainment
(sediment transport) by surface runoff ending in open waters on site. The amount of water exceeding the
design capacity of the collection system should be minimal.
Some excavation will Occur in soDs that are expected to have measurable levels of semi-volatile organic
chemicals. primarily phthalates. Because phthalates adsorb onto the soD particles and thus are not transferred
from soil to water in measurable quantities. surface water runoff should not cause a water quality concern as
long as erosion control measures are applied to all soils excavated during remedial action. The 1M/IRA
construction specifications will Include post-excavation erosion control measures. Techniques may include,
but not be limited to fiber composite nets. grouted riprock. hydromulching. and seeding.
South Walnut Creek Basin soils within au 2 are contaminated with plutonium and americium (Rockwell
International, 1989a). Prior to construction work for the surface water contamination cleanup, surveys will be

results from chemicals involved in the pretreatment of the waste stream and concentrated acids or bases
utilized periodically for descaling of equipment. Handling of the concentrated cleaning chemicals will be
governed by an OSA. as will the precautions for handling the dewatered solids generated in the water treatment
process. -
Dewatered solids will be handled as a low-level mixed waste. This will require solidification at an
existing RFP facUlty to meet the transportation and disposal requirements. The solidified waste will be disposed
of at the Nevada Test Site or slmDar facUlty after it is sampled and analyzed to determine compliance with
recently promulgated RCRA land ban restrictions.
The volume of waste will not be a major addition to those wastes already processed at the RFP. The
collection, transport, and treatment of the dewatered solids wUI be in accordance with standard Plant operating
procedures and does not present a significant hazard to on-site or off-site water quality.
The GAC adsorption system will provide even less prospects for negative impact to water quality on
site than the cross-flow membrane filtration system. The carbon columns will be fully self-contained and hold
approximately 2,000 pounds of carbon. The units are shipped to an off-site location for regeneration.
Approximately one gallon of water per 3 to 4 pounds of carbon (500 gallons) could be spilled during unit
changeout of the carbon column. This possibility is mitigated by the use of secondary containment which
captures all of the potentially spilled water. The net effect Is that there will be no spill during carbon column
changeout. Procedures will be established for the safe changeout of the exhausted GAC columns. The
transport of the exhausted GAC columns will be in accordance with standard Plant and project-specific
operating procedures and presents a negligible hazard to on-site or off-site water quality.

TERRESTRIAL IMPACTS
Terrestrial environment features that may be negatively impacted by the proposed 1M/IRA include
'r
animal life. plant life, and land forms Oncluding wetlands). These negative impacts are expected to be minimal.
because of the disturbance to the areas of concern caused by the Plant's construction and operation during
..
the past 37 years. These past disturbances have left the 903 Pad with an asphalt pad cap and the East
Trenches Area has surface evidence of burial trenches. The effects of the 1M/IRA wUI not significantly impact
the already-
-------
The proposed 1M/IRA is not expected to have an adverse effect on linear wetlands. In 1989. EG&G
authoriZed the preparation of a wetlands assessment for the entire Rocky Flats Plant site (EG&G. 1990b). This
1
report Identified 107 acres of areal wetlands and 84,970 feet of linear wetlands within the Rocky Rats Plant site.
South Walnut Creek is identified as one of six ephemeral streams traversing the property and is considered
~
relatively important as part of the site drainage system. The proposed action, as It impacts wetlands. will not
be discernible from current stream management.
No wetlands impact is expected from treating water prior to reintroduction into South Walnut Creek.
The proposed action calls for withdrawal of up to 37.5 gpm of contaminated surface water from station SW-61 ,
4.5 gpm from SW-59, and 18 gpm from SW-132. Water from these collection points will be diverted into
properly sized sumps and piped to a treatment plant equalization tank to provide the treatment plant with a
constant feedstock. Water from the treatment plant wUl be reintroduced Into South Walnut Creek immedialely
downstream of CS-132. Water diverted from the sources would be removed from the surface water system
for no more than 3-4 hours at 60 GPM and for no more than 48 hours at very low flows.
As mentioned earlier, treated water from the treatment system wUI be discharged into South Walnut
Creek, just downgradient of CS.o1 (the surface water collection system of SW.o1). The South Walnut Creek
basin contains a series of five on-channel reservoirs. The last pond In the series. Pond B-5, discharges directly
into South Walnut Creek. Water volume is managed by these ponds and is discharged directly to South
Walnut Creek in accordance with the Plant's NPDES Permit. Discharged water follows the South Walnut Creek
drainage north to the natural Walnut Creek drainage. Surface water flow in Walnut Creek near the property
boundary is currently being diverted around Great Western Reservoir, which is a drinking water source for the
City of Broomfield, and is then returned to the natural drainage channel. Due to the ephemeral nature of South
Walnut Creek, no impact to wetlands is anticipated as a result of the proposed action to treat surface water.
Although no long-term impact to wetlands is anticipated, It is possible that construction activities could
adversely affect a few wetlands plants during ditch modifications or sump installation. Replacement of any

ARCHAEOLOGY AND HISTORIC SITES

The 903 Pad, Mound and East Trenches Areas have been highly disturbed over a number of years.
Due to this disturbance and the topographic position of the subject area, the State Office of Archaeology and
Historic ~reseN8t1on has determined that this action will not Impact cultural resources (Burney, 1989).
An archaeological and historical survey of the RFP was conducted between July 18 and August 22.
1988, which determined two sites have potential eligibnlty to the National Register of Historic Places. However,
insufficient information currently exists to make this determination. These two sites are located northwest and
soUthwest of the investigation area, and wUl not be disturbed by the proposed action (Burney, 1989).

SHORT- AND LONG-TERM LAND PRODUCTIVITY
Land within au 2 is currently undeveloped and will remain so for the foreseeable fUture as part of the
Rocky Flats Plant. au 2 lies within the Rocky Flats Plant security boundaries and is not accessible to the
general public.

PERSONNEL EXPOSURES - ANALYSIS METHODOLOGY
The effects of personnel exposures to hazardous chemicals have been estimated in terms of increased
risks of either developing cancer (carcinogenic risk) or some other adverse health effect due to the exposure
(noncarcinogenic risk). Analyses were done separately for those directly involved in remedial actions (workers),
other RFP personnel not directly involved in remedial actions (site employees), and off.slte individuals (general
public). Detailed risk assessment calculations are provided in Appendix G.

Airborne contaminant concentrations at the receptor (site employees, general public) locations were
estimated using the Gaussian Plume Equation of Pasquill as modified by Gifford (1961) for ground-level
-
concentrations at the centertlne of the plume. Assuming a ground4evel release, the equation becomes:
x/a
=
(K (ly (lz u)"'
.
Where:
x = air concentration, mg/m3 or cijm3
Q = emission rate, mg/sec or ci/sec
u = wind speed, m/sec
(ly = horizontal dispersion coefficient, m
(lz = vertical dispersion coefficient, m
The dispersion coefficient value is a function of the downwind distance, whether the contaminant
emission Is a long-term (construction, operation) or a short-term (accident source), and the prevailing
meteorological conditions (PasquDI StabOity Class). Long-term dispersion coefficients were calculated using
.
Briggs formulas for open country conditions (Gifford, 1976), PasquUI Stability Class D (prevalent condition per
RFP EIS), and average annual downwind directional frequencies. Short-term dispersion coefficients were
calculated using formulas developed by Slade (1968), Pasquill Stability Class F, and no wind directional
averaging.
The toxicity assessment (intake and risk) for carcinogenic and noncarcinogenic effects of chemicals
was performed in accordance with the EPA's Risk Assessment Guidance for Superfund Sites (EPA, 1989).
EPA's Integrated Risk Information System (IRIS) was utUized as the primary source for toxicity information
(RFDs and slope factors). EPA's Health Effects Assessment Summary Tables for the fourth quarter of FY 1990
(EPA, 1990b) were used as a secondary source of information. For organic chemicals, inhalation toxicity
values (RFDs. slope factors) were estimated using the oral pathway values in those instances where inhalation
values were not avaBabie. It would be expected that the toxicity values for both pathways would be similar
due to similar absorption efficiencies for organic materials.
Estimates of carcinogenic risks were calculated for each of the organic chemicals identified in Table 4- 1 ,
and the individual risks summed for a total carcinogenic risk. The carcinogenic risks are considered to be
SURFACE WATE~ IP,_n\l! ._.7."'"
Marc:1" '991
-------
cumulative for the entire period of exposure and the calculations yield an estimate for the lifetime increased
risk of cancer.
..
Noncarcinogenic risks are considered 'hreshold" events. That is. no effect is observed below a given
exposure. The potential for increased health effects are expressed In terms of the non-cancer hazard quotient.
.
which equals the exposure level divided by the reference dose (noncarcinogenic toxicity value). The EPA
methodology assumes that a quotient value of less than one is unlikely to result In adverse health effects. even
for sens~ive popUation groups. Generally, the greater the quotient value above unity, the greater the level of
concern. Chronic or subchronlc reference dose values were utDiZed in the non-cancer hazard quotient
calculation, depending on the potential duration of the exposure.
Exposures to site employees and members of the general public were analyzed based on a single.
hypothetical individual for each exposure category. Site employees were assumed to be assigned. eight hours
a day for the duration of the release, to whatever buDding would receive the greatest average airborne
exposure. For the proposed action, the nearest occupied locations resulting in the greatest exposure to other
site personnel include BuDding 988, 995. and the Gate 9 guard post Onner guard post on east access road).
The analysis of the Impact to the general public assumed a single Individual would remain at the point of
highest exposure (due east at Plant boundary) accessible to the general public for each pathway, twenty-four
hours per day, for the entire duration of the release. These calculations provide an upper bound for the
increased risks to an Individual from each of these groups. During the remedial action. It Is unlikely that any
worker, site employee, or member of the general public would exceed or even approach the risks estimated
for their respective group.
In calculations of the estimated increased risks to members of the general public from hazardous
chemicals. the impacts on infants and young chDdren were calculated separately from those on adult members
of the population. Infants and young children differ from adults in the rate of uptake of the hazardous
chemicals and In body weight. Both of these factors influence the calculations of increased risk. To assess
noncarcinogenic risks. non-cancer hazard quotients were estimated for both children and adults. The numbers

quoted In the text of this document are those for the group with the greatest increased risk or concem.
Carcinogenic risks to a member of the general public were estimated assuming exposure for the entire length
.(
of the release, which was conservatively assumed to be thirty years. Two exposure categories were
considered: 1) the member of the public is already an adult when the project starts; and 2) the individual
..
Is assumed to be a child for the first five years of remedial action and an adult for the remaining 25 years. The
numbers in the report represent whichever analysis yielded the highest Increased risk of cancer.
The intake of radioactive materials has been assessed by calculating total intake by individuals and
converting that to Committed Effective Dose Equivalent (CEDE) using the exposure-to-dose conversion factors
for Inhalation (Table 2.1 of EPA, 1988). Internal Dose Conversion Factors for Calculation of Dose to the Public,
Part 2 (DOE, 19888), was used to assess dose to the public. The calcuiated exposure values are then
compared wtth the applicable DOE limits for each receptor group. DOE Order 5480.11 (DOE, 198Bb)
establishes a limit of 5 rem (eHective dose equivalent) per year for occupational workers. DOE Order 5400.5
(DOE. 1990b) Incorporates a Oean Air Act (eM) limit of 10 mrem (effective dose equivalent) per year for
members of the public from routine airborne emissions and a dose limit of 100 mrem per year from all
exposure modes.

Airborne Excosures to VOCs
..
It is proposed that the treatment facUlty be located In the East Trenches Area, nonhwest of IHSS.' '0.
Associated piping and utUities wBI be located, to the degree possible, to avoid soils contaminated with VOCs.
There will be monitoring to assess possible exposures to VOCs during these construction activities. Protective
measures appropriate for the level of VOCs detected wit be specified In the SSHSP to protect the workers.
The potential for chronic or routine exposure of workers to VOCs resuttlng from operations and maintenance
tasks will be small. OSA procedures will be established to control potential hazards to workers.
The treatment facUlty traDers will be ventUated to prevent the buUdup of VOC vapors in the work
environment. The process reaction, concentration. and neutralization tanks wDI be equipped with hinged
covers to minimize the introduction of VOC vapors into the work area. The filtration, dewatering, and carbon
adsorption units are closed systems and thus will not act as VOC vapor sources. Periodic (every' to 3 days)
removal of dewatered solids (sludge) from the dewatering equipment will be necessary. This will require
opening of the filter press housing and potential short-term exposure to VOC vapors. FacDIty ventilation and
OSA procedures wil provide appropriate personnel protection. The wet consistency of the sludge will preclude
potential aerosolization of radioactive particulates and associated exposure from inhalation. The dewatered
solids will be handled.8$ a low4evel mixed waste. Outdoor operational tasks, such as maintenance of the
surface water collection system. will be performed in accordance with the appropriate OSA.
Activities that might lead to nonroutine exposures, such as opening tanks or other maintenance
operations, WIll be of short duration and will not lead to chronic exposures. Monitoring these activities will be
necessary. however, to determine that adequate protective measures were used to assure that workers were
not exposed to VOC levels exceeding appropriate limits for the individual chemicals.

contact with soli contaminated with VOCs. The treatment facUlty will be constructed In the East Trenches Area,
northwest of IHSS-110, where VOC contamination levels are anticipated to be low. The piping for the water
treatment facility will be routed through uncontaminated so8 to the extent possible. Any excavated soil from
designated IHSSs will be treated as a RCRA mixed waste untY determined otherwise. Inorganic chemicals and
radioactive materials identified In the work areas are not readUy absorbed through the skin and would re$ult
in a negligible exposure pathway.
Personal protective measures may be necessary during some routine operations activities where there
Is a potential for contact with contaminated water (e.g., routine water sampling or solids removal in the
treatment facUlty). If such measures are necessary for the protection of the workers. they will be specified in
the OSA for those activities.
Inhalation of Fualtive Dust
Fugitive dusts are likely to be generated during construction activities for the water collection and
treatment facUlties. The Phase II Sampling Plan (EG&G. 1990&) Includes soH sampling in the areas of interest,
but the resutts are not yet available. For this reason, the surface soU conditions have been estimated using
available soU samples from the Phase I RI/FS (Rockwell, 1987a). Where soU samples were not available, the
nearest soU samples located between the area of interest and the most likely source of contamination have
been used.

The soil sample results indicate that the only organic chemical of concern in soil above the water table
is bis-(2-ethythexyl)phthaJate. Acetone and methylene chloride were reported but are suspected to be
laboratory contaminant artifacts. Consequently, It is the only significant organic chemical contributing to
\
carcinogenic and noncarcinogenic effects from the fugitive dust pathway. The radioactive contaminants of
concern from the fugitive dust pathway include plutonium and americium. The contaminant levels in the
~
surface' soils for C$-59, O$~1, 0$-132, and the treatment facUlty are based on data from the nearest available
borehole.
Dust control measures will be specified in the SSHSP to limit Inhalation exposures to workers involved
in construction activities. These measures will be derived from the PPCD. Even If workers were to be exposed
to the maximum dust loading permitted by OSHA regulations for nuisance dust during the entire period of
construction activities, the effects of either fugitive radioactive material or phthalates would be insignificatlt.
The contaminated surface water collection stations will have surface piping routed to the treatment
facUlty. Consequently, transfer of contaminated surface water by tanker truck will not be required and will not
result In a fugitive dust source term during operations. Occasional travel to the surface water collection
stations will be required for maintenance or surveillance purposes. WhOe some fugitive dust may be generated
in the wake of the vehicle, It Is not expected to be a significant exposure pathway for the vehicle operator or
other construction personnel.

7.7.2 Site EmDlovee Excosure Risks
Other workers at the RFP site could be exposed to low levels of VOC vapors released during normal
operation and to fugitive dust generated during Installation and operation of the facilities associated with the
proposed action.
Although the vent on the feed equalization tank (see Figure 6-1) on the water treatment facility will have
an activated charcoal filter attached, in order to estimate an upper bound to personnel exposure, a calculation

was performed to detennine the potential VOC releases from the vent without a filter attached. Since that tank
is the largest single tank in which untreated water is collected. It was chosen as the tank which. if unfiltered.
.(
could lead to the greatest exposures to other site employees or the public. Any other tanks. sumps. or pump
vents would lead to lower exposures and lower risks. In the calculation. It was assumed that the liquid in the
.
tank was at the contamination levels listed In Table 4-1 and that the vapor In the tanks had reached equilibrium
with the liquids. It was further assumed that the vapors are displaced by in-ftowing liquids at an average rate
of 60 GPM. the design processing rate. That Is. It Is assumed that the average liquid Inftow must equal the
processing flowrme. but no credit was taken for water being removed from the tank.
Under these
circumstances. the maximum total cancer risk and total non-cancer hazard quotient would be very low.
There will be dust generated during the construction of the water collection facUlties as well as the water
treatment facUlty. Although dust suppression measures will be implemented In accordance with the PPCD and
SSHSP. the following conservative analysis. which assumes no dust suppression measures and high estimates
of areal disturbance and construction time. has been used to estimate health risks from dust generation. The
dust generation rate was estimated using the construction generation rate eX 1.2 tons per acre per month
(average soil moisture conditions) from AP42 (EPA, 1985). AP-421s an EPA document for estimating source
terms for air pollutant emissions. It was assumed that the project would create dust over an average area of
one acre for two months. This multiplication led to a calculated average generation rate of 4.2 x 1004 kg of dust
per second. To be conservative in calculating the exposure of site employees. It was assumed that all the dust
was generated at the surface water collection stations. since this would produce the maximum exposure to
personnel at Buldlngs 988 and 995. The approach utDlzed to estimate surface contamination levels
contributing to fugitive dust has been discussed In the fugitive dust portion eX Section 7.7.1 of this report.
Using a wind dlrectJon weighted dispersion factor (X/Q) from CS-134 to BuUdlngs 988 and 995 of 2.43 x 1004
seconds per cubic meter, It is estimated that an Individual assigned to the buildings for the full sixty-day
duration of the construction activities would receive a maximum dose of 0.4 mrem CeDe from radioactive
materials In the fugitive dust. The corresponding incremental cancer risk and norH:ancer hazard quotient due
to the presence of phthalates and metals in the dust were calculated to equal 3 x 10. and 4 x 10-3. respectively.

As noted previously, the only potential fugitive dust source tenn associated with Interim action operation
is occasional travel to the surface water collection stations for maintenance or surveillance purposes. Due to
the Infrequent nature and short duration of any travel to the collection stations. chronic exposures to other site
~}
personnel from fugitive dust are not anticipated.
.
7.7.3
Risks to Members of the Public'
Members of the public could be exposed to the same sources of risk as described In the previous
section for other RFP site workers. The airborne concentration of the fugitive dust would be less for members
of the public because of the greater dispersion distance from the source.
The public may be exposed to fugitive dust containing phthalates. and plutonium generated during.1he
construction phase of this action. The maximum dose to a member of the general public from radioactive
contaminants present In dust generated during construction activities would be about 2 x 10-3 mrem CEDE.
This is very low and well within airborne exposure limits of 10 mrem per year to any member of the general
public (DOE. 1990b). The maximum incremental cancer risk to a member of the public due to phthalate and
metal contamination within the dust was calculated to be negligible during construction. with a value of 6 x 10-8.
The corresponding non-cancer hazard quotient was calculated to equal 8 x 1 O~ for construction activities. As
discussed in Section 7.7.2. some fugitive dust may be generated in the wake of vehicles traveling to the water
collection stations during normal operations for maintenance or surveillance activities. Due to the infrequent
nature and short duration of this travel and the distance to the plant boundary (approximately 1 mile), any
public exposure Is expected to be insignificant.
As discussed in section 7.7.2. potential VOC releases from the feed equalization tank were analyzed
to provide an upper bound on the risks from releases from other. unfiltered tanks.
Using the same
Throughout this report the term "general public" hu a special and very reltric:t8d meaning. In order to estimate the maximum
exposure or risk to any individual outside of the RFP lite. all estim&t81 are bu8d on exposure to a person at the site boundary
location having the highest a\l8rag' airborne concentration who remains there for 24 houri ,ach day. 365 days ,acn year. for

assumptions as described in section 7.7.2. the maximum cancer risk and non-cancer hazard quotient for a
member of the public would be very low.

7.8
PERSONNEL EXPOSURE - ACCIDENT
.
Any accidents that may occur during the construction phase of the proposed action are those typical
of small excavation or construction activities. The SSHSP wli identify appropriate precautions and
responsil:?illtles for each Job. Workers wUl be tamliar with the SSHSP and a copy of It wUl be available at the
work site. No credible accident during construction would lead to exposure of either workers. site employees.
or members of the public to levels greater than those res~ng from the severe accident case analyzed below.
During operation. accidents that could Impact either workers or members of the public would incl~e
fires or major spUls of contaminated material. Splls of untreated water wtthIn the treatment facility would create
the potential for short duration airborne VOCs. Uptake of contaminants by workers involved in the cleanup
would be controlled by following safety precautions specified in the OSA Any airborne VOC releases through
ventilation systems that could lead to exposures of other RFP employees (site employees) or the general public
would be less than the tank rupture discussed later In this section.
The Initiation and propagation of fire within the treatment facllty Is a credible accident. The facility
traDers are equipped with chemical fire extinguishers; however. the traUers wli not normally be occupied once
operations become routine. Any VOC releases would be bounded by the severe accident case since
concentrated VOCs woUd be contained within the acttvated charcoal columns which are closed components
and filled with water. Solids which are in the filter press housing or which have been removed and placed in
metal containers constitute a potential radioactive material source tenn. A fire would have to both dry out and
aerosolize the solids as well as breach the metal containment to reBUt In a radioactive release. Since the
solids are Inorganic and in a sludge form containing 60 to 70 percent water and are within metal containers,
and the traDer Is the only major combustible material present, It Is concluded that the fire duration and intensity
would be insufficient to result in a radioactive material release resulting in any significant impacts.

-------
If any workers were present during an accident Involving the rupture of the inlet tank, the danger of
traumatic Injury would be a greater concern than intake of hazardous chemicals or radioactivity. The
radloacttve materials present In the water are not volatile, nor are they readly absorbed through the skin. so
they do not present an ingestion hazard to the workers at the scene of the incident. The organic chemicals
')
are low In concentration and would not voiatUlze Immediately. Thus, whle the airborne concentration levels
.
near the tank would be higher than off-site or other on-slte locations. the workers would be aware of the
incident and would either evacuate or take protective actions. thus limiting their total exposure to the hazardous
material..
7.1
COMMITMENT OF RESOURCES
The scope of the proposed 1M/IRA is small and the resources (material/human) for construction and
operation of this surface water treatment system will likewise be relatively small. No significant commitments
of valuable resources are Involved.
WIth the exception of the land area. all of the materials for construction and operation of the water
treatment system will be irrevocably and irretrievably committed to the Implementation of the remedial action.
Most of these resources are normally consumed at the Plant at a rate which makes the requirements of the
remedial action Insignificant. The water pretreatment chemicals and cleaning solutions are already in use at
the RFP. The chemicals for the cross-flow membrane treatment system and the carbon canisters are all readily
avaUabie from oIf-site sources. Process chemicals, cleaning agents, and carbon wUl all be available within the
Denver metr~1tan area.

and are derived from nationwide Department of Transportation (DOT) statistics.
The proposed action wUI involve transportation activities during the construction phase as well as during
subsequent operations. All construction shipments are anticipated to be made mostly by truck and wili

originate within the Denver metropolitan area (within a SO-mAe radius of the Plant site). Materials to be brought
on site Include the treatment systems, storage tanks, piping, concrete, and associated equipment. The delivery
of these material. wi! require several truckloads over the construction period, followed by routine maintenance
travel between collection areas and the treatment facilltle8 (estimated at less than 50 miles per week). The
}
resulting transportation Impacts will be smail as seen from the tabulated emissions and health effects estimates.
To place transportation Impacts to the general public in perspective. It Is observed that approximately 60.000
.
round-trip truck shipments (one-way distance of 50 mUes) would be required to resutt In one additional latent
cancer fatality (LCF). An average of 210,000 truck shipments woUd be required to resutt In one additional
traumatic fatality. The increase in site travel during construction may be noticeable but will be of shon
duration. Outside the Plant boundary, the increase will not be noticeable.
Treatment of contaminated surface water from OU 2 wli r~ in an Incremental increase in site pickup
and deliveries of spent carbon columns and replacement units and chemic81s for the pretreatment of water for
the cross-flow membrane treatment system. Deliveries wli be spread out over the course of the year and will
be handled by one of the existing Plant chemical suppliers. The very small number of shipments involved for
both the carbon columns and the cross-flow membrane treatment system will result in an insignificant impact
to human health.
Off-site transportation Impacts associated with the shipment of solidified fitter sludge to a mixed waste
disposal site. such as the Nevada Test Site, wDI be very low as determined In DOE (1990b). Relatively low
concentrations cA contaminants. the physical form of the waste. disposal site waste acceptance criteria. and
compliance with DOT packaging and transport requirements all contribute to very low health effects from
incident-free shipment and accident events.
Operational activities wDl also include periodic Inspection of the collection system to remove debris or
other obstacles. as well as routine inspection of the pipeline collection system providing direct feed to the water
treatment facUlty. This wUl require vehicular travel to each collection station area. which is estimated to total

CUMULA~IMPACTS
.
Routine processing of the surface water collected from the surface seeps and drainages will result in
some additional solid wastes being generated from the site. Generation of flter press cake by the cross-flow
membra~ fItratIon system Is estimated to be a maximum of 70 cubic yards annually. The filter cake will be
treated on site and shipped to the Nevada Test Site or simler facllty for final disposal. The annual production
rate of the semisolid wli average much lower. All gaseous releeS88 wli be undetectable off site. None of the
materials that may be releesed are expected to be cor_.tIlltted by any natural process.
The drying of the semisolid sludge waste from the treatmenI system will require an increase in Plant
solidification operations to dry and package the waste for transport to a final disposal site. Neither the drying
nor packaging requirement wli add significantly compared to the current wor1doad of the facUlty. Radionuclide
accumulation in the sludge Is not expected to exceed exempt quantitJes by weight, so that shipment of the
sludge Is not expected to cause any special concern or require unusual controls.
It Is estimated that four workers wli be involved In routine operation and maintenance of the surface
water collection and treatment facllty. This wli have negligible Impact on the worldoad of Plant personnel.
In routine operations, these workers wli not be exposed to any levels of chemicals or waste stream pollutants
that would resIrict them from other assignments at the RFP.
Construction actMties will r.ut In increased vehicular traffic, engine emissions, and the number of
workers. The number of personnel required for the proposed action wit be a small Increase to the assumed
year1y additional construction loading.

SECTION 8
ENVIRONMENTAL EFFECTS OF THE ALTERNATIVES
{
The preferred alternative and the proposed action for this interim remedial action is to gather
.
contaminated surface water from a series of point sources, transfer the collected water via pipeline, and
process the water through a water treatment system. The preferred treatment system consists of a cross-flow
membrane treatment system for removal of radlonuclldes and metals, followed by a carbon column system
for removal of VOCs. The treated water will then be returned to South Walnut Creek.
Several alternatives to the proposed 1M/IRA were evaluated for environmental effects. The alternatives
included: 1) no action; 2) surface water collection at Pond 8-5 and 3) ion exchange, granular media filtration
with polymer addition. UV peroxide oxidation, and air stripping. The alternative of surface water coIlection,at
Pond 8-5 has been eliminated based on the potential of generation of additional contamination and additional
volumes of water requiring treatment (See Section 4-1). Each remaining alternative is evaluated in regard to
environmental quality, personnel exposure and transportation impacts. Following the alternative evaluation,
Table 8-1 compares the potential Impact of the proposed action with the alternatives.
8.1
ENVIRONMENTAL EFFECTS OF NO ACTION
Although the no action alternative Is In direct conflict with the lAG reached among DOE, EPA. and the
State of Colorado, It Is discussed herein.
8.1.1
Environmental Oualltv
The No Action alternative would not involve any short-term impact to the environment or the work
force/general population and would eliminate the need for off-site transportation activities. However, it would
not contain nor remove any radlonuciides, VOCs or Inorganic contaminants. The No Action alternative would
pose a long-term release risk to the general public and would require remedial actions in the future.

Marc:1"\ 199'
-------
The No Action alternative would require that the current quarterty site monitoring be continued.
Because the monitoring Is a part of the existing plant environmental monitoring program, the impact on plant
operations and the surrounding community would be effectively zero. However, because off-site migration
~
may occur in the future, the No Action alternative is unacceptable.
.
8.1.2 Personnel ExDosure
T~ No Action alternative wDl have minimal Impact on currem workers at the site or at adjacent sites.
Workers would stOI be required to collect quarterty sampling, which would presem no additional impact above
currem impact levels. The sources of hazardous materials would neither be removed nor comrolled. However,
the posslbUity of releasing contaminated water off-site would increase over time. The site would then be a
source of public exposura In the long term.
8.1.3 Transcortatlon
Since no remedial action would occur under this alternative. there would be no an-site or off-site
transportation activities associated with this alternative or related impacts to workers or the general public.
8.2
ENVIRONMENTAL EFFECTS OF ALTERNATIVE 2
8.2.1
Environmental QualItY
A variety of treatment technologies were investigated as alternatives to the proposed au 21M/IRA.
These included granular media fBtratlon with polymer addition for suspended solids removal and ion exchange
for metals and radionuclide removal. In addition, UV peroxide oxidation and air stripping with off-gas treatment
were examined for organic comaminam removal. Ion exchange and UV peroxide systems are proposed for
treatmem of comamlnated ground water at the 881 Hillside Area which comain constltuems which are similar
to the OU 2 surface water comaminants. However, with regard to ion exchange, plutonium is not a ground

water contaminant at the 881 Hillside Area. and ion exchange (or other inorganic treatment technologies) are
not proven technologies for removal eX plutonium for natural water. There 15 no appreciable difference in
{
environmental Impacts eX the alternative organic contaminant treatment technologies. The cross-flow
membrane filtration system is the only proven system for removal of the targeted radionuclldes.
.
8.2.2 Personnel Excosure
The use of alternate treatment technologies would have little Impact on the personnel exposure
associated with surface water cleanup. The contaminants in the water remain the same and the removal
techniques are essentially simUar with respect to personnel exposure a risk.
8.2.3 TransDOrtatlon
The selection of one of the other atternatlve treatment technologies may require different transportation
requirements, dependent on the rate eX water treated and the contaminants to be removed. The ion exchange
columns utDlze resin beads that may require periodic replacement. Using a UV peroxide treatment process
would reduce transportation Impacts primarily due to elimination of some of the by-product materials produced
by the process. Overall, the transportation Impact for this alternative is minimal.
8.3
SUMMARY
The Impacts of the altematlves are judged to be small. The potential impacts associated with the
proposed action and each eX the identified alternatives are presented in Table 8-1-A and B.

Hazard quotient is ratio of daily intake at level of ARAR based on the consumption ot 2 liters/day and a body weight of 70 kg to the chronic
oral RfD (EPA, 1990b - Health Effects Assessment Summery Tables, Fourth Quarter, FY 1990). RfD = Agency-wide reference dose, developed by an
inter-office work group chaired by the Office ot Research and Development, u.S. EPA, Washington, D.C. Cancer Risk = ARAR (ug/l) x Carcinogenic
Slope Factor (ug/I r'
For radionuclides cancer risk = ARAR (pCi/l) x Pathway-specific unit risk (pCi/l)". The cancer risk is not applicable to gross alpha and
beta. Cancer risk depends not only on the form of radiation, but also on the radlonuclide etnitting the radiation because radionuclldes
selectively affect various organs.

This section establishes
pre-treatment standards
(both general and
categorical) for the control
of poltutant discharges into
Public OWned Treatment Works
(POTW). Discharge of POT"
nust not cause pass-through
interference, violation of
specific prohibitions, or
violations of local
I Imitations or ordinances.
POTW should el ther have an
EPA-approved pre-treatment
program or have sufficient
mechanl SIIIII to meet the
requirements of the national
pre. treatment program In
accepting CERClA waste.
Use of best available
technology (BAT)
economlcalt y achievable Is
required to control toxic
and non-conventional
pollutants. Use of best
conventional pollutant
control technology (BCT) is
required to control
conventional pollutants.
Technology-basedllmltatlons
may be detenlllned on a case-
by-case basis.

The strategy Includes
guidelines on classifying
ground water for EPA
decisions affecting ground
water protection and cor-
rective actions. Criteria
include ecological I~rt-
ance, replaceablilty, and
vulnerabl I I tyconsiderat Ion.
National alT'blent air qual Ity
standards have been set to
attain and maintain primary
