2.  Ensure the remedies are protective of human health and the
    environment\
    for the life of the project;

3.  Ensure the RAs meet all performance standards specified in the
    **1995\
    Off-Post Record of Decision (ROD)** and **1996 On-Post ROD** and
    modifications, approved final RDs, Five-Year Review Recommendations
    and negotiated project approaches - in coordination with EPA\'s
    regulatory partners, Colorado Department of Public Health and
    Environment (CDPHE) and the Tri-County Health Department (TCHD);

4.  Ensure RAs are consistent with RMA specific agreements, completed
    RMA projects and on-going RD/RA; and

5.  Conduct pro-active community outreach efforts concerning RMA
    activities in cooperation with the U.S. Army, Shell Oil Company, and
    U.S. Fish and Wildlife Service (collectively referred to as the
    Remediation Venture Office (RVO)) and CDPHE and TCHD.

RMA was established in 1942 with the primary mission of manufacturing
and assembling chemical warfare agents, agent-filled munitions, and
incendiary munitions to support the World War II effort. The South
Plants manufacturing facility was part of the initial facility building
activities. Actual plant production began in December of 1942. During
World War II, RMA manufactured 87,000 tons of chemical, intermediate,
and toxic products, and 155,000 tons of incendiary munitions. Munitions
produced in South Plants during World War II included chlorine,
Levinstein Mustard (H), Distilled Mustard (HD), Lewisite or M-1 (L) and
arsenic trichloride. The following list shows the amount of these
chemicals that was produced.

> Chlorine 63,360,000 pounds
>
> Levinstein Mustard 7,132,000 pounds
>
> Distilled Mustard 23,912,000 pounds
>
> Lewisite 9,106,000 pounds
>
> Arsenic Trichloride 5,360,000 pounds

After 1945, portions of RMA were leased to private industry. In 1947,
Colorado Fuel and Iron (CF&I) leased a portion of the facility to
produce chlorinated benzene and other chemicals. Julius Hyman and
Company also began the manufacture of a variety of pesticides,
insecticides, and herbicides during that period. Hyman assumed the CF&I
lease in 1950 and, in 1951, Shell Chemical Company assumed the Hyman
lease. Shell continued manufacturing until 1982.

At the beginning of the Korean War in 1950, the North Plants facility
was constructed at RMA for the production of nerve agent (GB or Sarin
and VX). Manufacture of Sarin occurred between 1953 and 1957. Munitions
filling operations continued until 1969. Other items produced include a
biological anti-crop agent that causes wheat rust; white phosphorus
grenades and shells for the Vietnam War; and a facility for the blending
of rocket fuel using hydrazine and unsymmetrical dimethylhydrazine.
Although the exact manufacturing processes employed to produce the
various chemicals are not readily available, it is known that at least
some of the processes required large amounts of organic solvents.

In the 1950s and 1960s, obsolete and deteriorating World War II ordnance
were demilitarized at RMA by either draining and neutralizing the
contents and burning the remains, or by controlled detonation or open
burning. In the early 1970s obsolete mustard agent was destroyed.

Common industrial and waste disposal practices used during production
years (1942 -- 1982) resulted in contamination of structures, soil,
surface water, and groundwater. Contaminants were introduced in the RMA
environment through disposal of liquid waste in open basins, solid waste
and munitions burial in trenches, accidental spills of feedstock and
product chemicals, leakage from sewer and process water systems,
emissions from air stacks, and use of commercial chemical products
during normal facility operations. Most of the waste products from all
of the various manufacturing processes were disposed in a series of
unlined basins. The original disposal area for liquid waste from 1943
through 1956 was Basin A, located in Section 36 of RMA (see attached
map). Overflow from Basin A continued through open drainages to a series
of successive open basins (B, C, D, and E). Other areas within Section
36 received a variety of liquid and solid wastes, generally in open pits
or trenches that were subsequently covered. Evidence of off-post
migration of contaminants produced by chemical mixing within the waste
basins was first noted in 1955. As a result, in 1957, an asphalt lined
basin (Basin F) was constructed in an effort to contain these wastes,
and it received subsequent waste until 1982. In addition, liquid waste
was taken directly from chemical sewers and disposed underground in the
Deep Well Injection Facility in 1964.

There are numerous contaminants of concern at RMA as a result of the
extensive manufacturing and experimental activities that occurred at
RMA. The following is a partial listing of the over 600 contaminants
identified in soils, surface water and ground water at RMA, particularly
in the South Plants and Basin A areas.

> In 1975, the Army and Shell initiated actions to protect on-post and
> off-post human health and the environment through the implementation
> of priority Interim Response Actions (IRAs) to remediate the most
> contaminated areas. Prior to issuance of the On-Post and Off-Post

Most of RMA was designated as a Comprehensive Environmental Response,
Compensation, and Liability Act (CERCLA), National Priorities List (NPL)
site in July 1987. The remainder, Basin F, was listed on March 6, 1989.
On February 17, 1989, a **Federal Facility Agreement (FFA)**, which
formalizes the organizational coordination process and provides the
framework for remediating RMA, was signed by the Army, Shell, EPA, U.S.
Department of the Interior, U.S. Department of Justice, and the Agency
for Toxic Substances and Disease Registry. The Army conducted a \$115
million Remedial Investigation/Feasibility Study (RI/FS) to fill data
gaps regarding the on-post and off-post contamination, evaluate remedial
alternatives, and select remedies.

The RI identified contamination within approximately 3,000 acres of
soil, 15 groundwater plumes, and 798 remaining structures. The most
highly contaminated soil sites are located at South Plants (Central
Processing Area, Hex Pits, and Buried M-1 Pits), Basins A and F, the
Lime Basins, and the Army and Shell disposal trenches. Soil data
collected during the RI are summarized in **Contamination Assessment
Reports (CARs**) for over 180 individual sites of suspected
contamination. The primary contaminants at these sites are pesticides,
solvents, heavy metals, munitions debris, and agent-byproducts, which
are found in both soil and groundwater.

The RI identified contaminated groundwater plumes primarily in the
vicinity of the basins, North and South Plants, and the northern and
western sections of RMA. Groundwater plumes are flowing primarily
north-northwest, and are largely intercepted by the boundary groundwater
capture and treatment systems located west, northwest, and north of the
major source areas. Five of the 14 IRAs included the construction of
various treatment facilities to treat contaminated water.

An endangerment assessment was completed in 1994 and is documented in
the **Integrated Endangerment Assessment/Risk Characterization**
(IEA/RC). Data collected during the RI/FS, together with the results of
the endangerment assessment, were used to develop and evaluate potential
clean-up options. The clean-up options are documented in the **Detailed
Analysis of Alternatives**, completed in 1995.

> During the RI/FS process, in October 1992, President George H. W. Bush
> signed into law the Rocky Mountain Arsenal National Wildlife Refuge
> Act of 1992 (**Refuge Act**) in recognition of the unique urban
> wildlife resources within RMA. Through the Refuge Act, most of RMA
> will become a National Wildlife Refuge upon EPA's certification that
> remediation has been completed.
>
> On December 19, 1995, an Off-Post ROD was signed which specified the
> remedy for groundwater contamination north and northwest or RMA.
> Requirements of the 1995 Off-Post ROD have been completed with the
> exception of continued operation and maintenance of the Off-Post
> Groundwater Intercept and Treatment System north of RMA and other
> boundary treatment systems. The selected remedy included tilling and
> revegetation of 160 acres of soil, inclusion of deed restrictions, and
> development of notification procedures for future well permit requests
> within the identified groundwater plume north/northwest of RMA.
>
> On June 11, 1996, the Army, EPA and the State of Colorado signed the
> ROD for the On-Post OU, with concurrence from Shell and the USFWS. It
> specified the remedy to be implemented for the entire On-Post OU of
> RMA including remedial actions for soil, structures, and groundwater.
> The selected remedy for the 1996 On-Post ROD includes: continued
> operation and maintenance of the water treatment facilities that were
> constructed as IRAs; construction of an on-site, state-of-the art
> hazardous waste landfill for containment of soils and debris which
> present an unacceptable risk to human health (including a double lined
> landfill referred to as the Hazardous Waste Landfill, and a triple
> lined landfill referred to as the Enhanced Hazardous Waste Landfill);
> consolidation into Basin A of soils and debris which present an
> unacceptable risk to biota; demolition of structures and consolidation
> of structural debris in the on-site hazardous waste landfill or Basin
> A, depending on the structure contamination history; excavation of
> contaminated soils from the identified 3,000 acres of RMA for
> containment within the hazardous waste landfill (approximately 1.7
> million cubic yards) or Basin A (approximately 1.5 million bank cubic
> yards); construction of RCRA Subtitle C covers over the hazardous
> waste landfill, and construction of RCRA-Equivalent and other soil
> covers over contamination remaining in place; and provision of an
> alternate water supply to all existing well owners within the DIMP
> groundwater plume north of RMA.

> The 31 major projects which comprise the On-Post remedy are scheduled
> to be physically completed by the enforceable deadline of September
> 30, 2011. The Army anticipates receiving increased funding in FFY 08
> and 09 such that construction of the remedy projects is accelerated to

**[Task 001 -- Community Relations]{.underline}**

[General Description]{.underline}: Provide support for community
outreach efforts, including public meetings and presentations.

[Specific Requirements]{.underline}**:** The Contractor shall furnish
the personnel, services, materials, and equipment required to assist
with EPA\'s community involvement program. Because the Rocky Mountain
Arsenal is located within an urban community, there are residents,
businesses, and schools in close proximity to the RMA fence line. As a
result, the community is very involved and concerned with the activities
at RMA. Two primary community boards, the Restoration Advisory Board
(RAB) and the Site-Specific Advisory Board (SSAB) actively oversee
implementation of the remedy at RMA. The SSAB has also obtained a
Contractor under an EPA-issued Technical Assistance Grant (TAG) that
provides substantive public comment on some documents issued by the RVO
or EPA for public review.

The Contractor shall work closely with EPA to ensure community outreach
is conducted in harmony with remedial response activities and EPA\'s
oversight thereof, to achieve community understanding of the actions
taken by EPA, to obtain community input, and to seek community
concurrence for EPA actions.

The Contractor shall play a substantial role in the preparation of
responsiveness summaries for EPA documents issued for public comment,
such as partial deletions from the National Priorities List (NPL), and
shall review and contribute to responsiveness summaries prepared by RVO.
The responsiveness summaries may be substantial in length. Historically,
responsiveness summaries for deletions have varied in length from a few
pages to as many as 80 to 100 pages, predicated on the number of
comments received by EPA. Preparation of responsiveness summaries
requires personnel with a comprehensive understanding of RMA and the
technical aspects of the query posed by the public comments, detailed
knowledge of the contamination history at RMA, and an understanding of
public concerns.

The Contractor shall draft fact sheets for diverse audiences. For
example, the Contractor may be asked to draft a fact sheet for
international visitors to RMA.

    applicable experts.

-   The Contractor shall provide expertise that are capable of
    supporting EPA in its oversight of the remedial design,
    construction, and post-construction monitoring and performance
    evaluation of over 400 acres of covers at the Rocky Mountain Arsenal
    (RMA) Site that must achieve equivalent performance standards to
    prescriptive covers established under the Resource Conservation and
    Recovery Act for containment of hazardous waste.

-   Formal RMA-specific, multi-agency agreements. These may include
    agreements on the design and implementation approach developed in
    multi-agency work group meetings, consistency with historical
    documents, resolutions of other relevant issues, and other
    agreements

-   ROD changes made through Fact Sheets, ESDs, and ROD Amendments

-   Previously approved RD documents and approaches

-   Lessons learned from implementation of previous RAs at RMA

-   Relevant historical RMA documents, Agreements, MOUs, and Decision
    Documents; and

-   Evaluation of historic field and analytical data using database
    query, data manipulation, and Geographical Information System (GIS)
    analysis

The Contractor shall consider the following specific documents when
conducting document reviews:

-   [RD of alternative covers]{.underline}: Review of RD documents
    requires expertise in alternative covers and in restoration
    ecology/revegetation, knowledge of RMA site-specific agreements
    related to covers, lessons learned from various studies, and
    specific requirements of the ROD, the Resource Conservation and
    Recover Act (RCRA)-Subtitle C requirements for covers, and knowledge
    of borrow source characteristics. This expertise is needed for
    oversight of the remedial design of over 400 acres of covers that
    must be equivalent to standards established under RCRA for
    containment of hazardous waste at the RMA CERCLA Site. The design
    and construction of these covers is precedent-setting throughout the
    nation.

-   [Five-Year Review report]{.underline}: Review of this report
    requires comprehensive knowledge of the RMA remedial actions that
    have occurred, are on-going, and are not yet started. Assessment of
    conclusions made in this report with respect to whether a remedial
    action is protective of human health required review of CCRs,
    certification designation documents, compliance documents, and
    'operating properly and successfully' determinations; knowledge of
    EPA guidance regarding five-year reviews, ROD changes, construction
    close-out, institutional controls, and operation and maintenance;
    downloading and independently evaluating soil, water, and air data
    from the RMA environmental database (RMAED); preparation of maps and
    figures; expertise in groundwater hydrogeology, contaminant fate and
    transport for compounds unique to RMA, groundwater treatment, and
    practical quantitation limits; knowledge of site-wide programs, such

    efficient to finalize the document internally. The Contractor shall
    prepare documents that may be needed as a result of unforeseen
    circumstances that arise in the course of fulfilling the regulatory
    obligations of EPA. For example, in the course of overseeing the
    construction of the Shell Trenches, EPA may request the Contractor
    to prepare a document evaluating the performance of the cover
    including the results of the moisture sensors.

[Deliverable Schedule for Document Review]{.underline}: The Contractor
shall provide the EPA COR with two copies (original plus one) of all
deliverables and drafts. Some deliverables will follow the normal
deliverable schedule, while others may have rapid turnaround times, e.g.

sample collection, sample analysis, and equipment storage and
maintenance. The Contractor shall conduct air sampling on the basis of
the current EPA Collocated Air Monitoring QAPP/SAP using EPA-owned, and
Contractor-operated monitoring equipment. The monitoring equipment is
operated at three air stations (1 stationary and 2 mobile) and has been
rotated on an established basis between 6 monitoring locations (AQ1,
AQ2, AQ3, AQ5, VL1, and VL2). The Contractor shall provide maintenance
and operation of the special test equipment for this program. Samples
are collected on a 3-day, 6-day, or 12-day frequency, depending on the
station and the nature of the active implementation projects, or on an
average 6-day frequency.

This task will occur through the second quarter of FFY 2008. Thereafter,
the air monitoring equipment will be stored and maintained in a
"stand-by" mode for reactivation within two weeks of notification by
EPA. Reactivation of EPA's co-located air monitoring program will be
dependent on air monitoring results obtained through the Army's air
sampling program. Beginning in FFY 2009, and after receipt of the Army's
annual Air Pollution Emission Notice (APEN), the Contractor shall submit
an annual evaluation of the current EPA QAPP/SAP for adequacy to
reactivate the co-located air monitoring program.

The Contractor shall use an Access-based database for managing EPA's and
RVO's air quality data. Quarterly reports shall be prepared and
submitted to EPA presenting and discussing meteorological data, EPA's
collocated monitoring results for particulates, metals, mercury, VOCs,
and OCPs, and comparison of EPA's results with RVO's results.

The Contractor shall prepare and issue an annual draft report of air
monitoring data to EPA.

3\) [Confirmatory Soil Remediation Sampling Participation:]{.underline}
The Contractor shall identify any data gaps in the RVO\'s site database
and proposed confirmation sampling program for each RA project, and make
recommendations to address these data gaps. The Contractor's sampling
and analysis recommendations are utilized in developing a joint
regulatory agency approach between EPA, CDPHE, and TCHD for identifying
locations for confirmatory samples, and areas of potential contingency
volume soils. Any recommendations from the regulatory agencies not
accepted by the RVO may be assigned to the Contractor for incorporation
into a single umbrella SAP with project-specific amendments to address
the data gaps. If an umbrella SAP and subsequent sampling is required,
EPA will provide specific instructions through a written TDM.

In addition, requirements and opportunities for collection of
confirmatory samples shall be identified by the Contractor where
historical information and institutional knowledge suggests samples are
warranted. The Contractor shall manage the confirmatory sample and
contingent soil volume records for EPA, independently of RVO, and assist
in the resolution of any discrepancies between the records. Often, for a
given situation, there are differing viewpoints between RVO and the
Regulatory Agencies with respect to whether sampling is warranted, and
if conducted, whether those samples should be considered confirmatory
samples as identified by the ROD. The Contractor shall support EPA in
negotiations regarding whether samples are confirmatory or RVO samples,
and similarly, whether identified contaminated soil volume is contingent
soil volume. The Contractor shall support EPA in setting the schedule
for the collection of the remaining confirmatory samples to ensure
samples are utilized (with some held in reserve) by the time the
enhanced hazardous waste landfill is closed.

4)  [Groundwater Well Installation and Collocated Sampling of Off-Post
    Plumes]{.underline}: The Contractor shall install and sample wells
    associated with collocated monitoring of off-post groundwater
    plumes. The Contractor shall collect semi-annual, collocated or
    split samples from four off-post groundwater monitoring wells, and
    provide laboratory analyses for a list of contaminants to be
    determined by EPA. Specific requirements for groundwater sample
    collection are to be determined. The Contractor shall also collect
    duplicates at a frequency of 20 percent of the total number of
    samples. The Contractor shall perform data verification on 100
    percent of the samples, and data validation on 10 percent of the
    samples. Results from these monitoring activities shall be
    incorporated into the annual split sampling reports.

[Deliverable Schedule for Sampling Oversight:]{.underline} The
Contractor shall provide the EPA COR with two copies (original plus one)
of all deliverables and drafts. Some deliverables will follow the normal
deliverable schedule, while others may have rapid turnaround, e.g. 24
hours, as much as 10% of the time.

-   [Oversight Sampling and Analysis]{.underline}: Deliverables will be
    due within 20 calendar days of receipt.

-   [Water and Soil Program Annual Draft and Final Report]{.underline}:
    Deliverable due date to be determined in writing by EPA.

    air, water, and soil, and approximately 500,000 records for water
    level measurements from the RMA environmental database

-   Operate and maintain GIS capability and provide support services and
    mapping capabilities to support all other oversight tasks, including
    maintaining current GIS data and coverages based on information
    provided by RVO

[Specific Requirements]{.underline}**:** The Contractor shall develop
and maintain Access relational databases in support of the oversight
activities at RMA. These databases are customized to include queries,
forms, and reports using SQL, macros, and Visual Basic for Applications.
Tables in these databases are developed from several sources, including
but not limited to the Rocky Mountain Arsenal Environmental Database
(RMAED), as-built survey data from remedial actions, hard copy project
documents and oversight reports, facility descriptions, results of
environmental measurements, hazard characteristics, target descriptions,
remedial action schedules, costs, obligations, outlay projections, and
other financial information, and applicable regulations and criteria.
Currently maintained databases include the following:

-   EPA Contacts List

-   Post RI Soil Samples

-   Confirmatory (CSV) Samples

-   Annual Oversight Sampling Program Databases
