Environmentally Preferable
Purchasing Program
Environmentally Preferable Purchasing (EPP) ensures that environmental
considerations are included in purchasing decisions, along with traditional fac-
tors, such as product price and performance. The EPP Program provides
guidance for federal agencies to facilitate purchases of goods and services
that pose fewer burdens on the environment.

Foreword
The federal government purchases more than $200 billion worth of goods and services each
year. Recognizing that purchasing decisions can have environmental consequences, the
federal government is beginning to incorporate environmental considerations into its pur-
chasing practices. As directed in Executive Order 12873, Federal Acquisition, Recycling, and
Waste Prevention, the U.S. Environmental Protection Agency (EPA) issued its proposed Guidance
on Acquisition of Environmentally Preferable Products and Sendees to help federal agencies
include these considerations when making purchasing decisions. The proposed Guidance estab-
lishes guiding principles to help identify products and services that have a lesser or reduced effect
on human health and the environment.
EPA's proposed Guidance acknowledges that environmentally preferable purchasing is a dynam-
ic concept that, depending on the product category, will not necessarily be implemented in the
same manner from agency to agency or even within a specific agency. In order to demonstrate
some of die ways environmentally preferable purchasing principles are currently being applied,
EPA is documenting various pilot procurement projects undertaken by executive agencies, state
and local governments, and the private sector.
The Department of Defense (DOD) Parking Lot Renovation case study documents one of these
projects. This report describes DOD's efforts to introduce environmentally preferable purchasing
into a 5-year, $1 million per year parking lot renovation contract at several Washington, DC area
facilities, including the Pentagon. This case study examines in detail the approach undertaken by
DOD, the assistance provided by EPA, and the lessons learned. Most importantly, it demonstrates
the feasibility of including environmentally preferable purchasing principles into federal contracts.
We hope the lessons and insights documented in this case study will help you and your organiza-
tion as you begin incorporating environmental preferability into your purchasing decisions.

Paving the Road To Success
INTRODUCTION
The U.S. Department of Defense (DOD) maintains some of the largest buildings
and facilities in the world. It also maintains some very large surface parking
lots and has recently begun using products with multiple environmental attrib-
utes to maintain some of them. On June 4, 1997, DOD awarded a 5-year, $1 million
per year contract to maintain and repair the parking lots and access roads at four
Washington, DC, area facilities—the Pentagon, the Court of Appeals for the Armed
Forces (Military Court of Appeals), the Federal Office Building Number Two (Navy
.Annex), and the Hybla Valley Federal Building. The contract includes several unique
features to ensure diat die work not only meets all price and quality concerns, but also
incorporates the use of products with multiple environmental attributes whenever fea-
sible.
The new DOD parking lot contract is significant for several reasons:
• It introduces environmentally preferable purchasing at some of DOD's largest
and most recognized facilities, most significantly the Pentagon, which houses
DOD headquarters.
• It promotes the use of products with multiple environmental attributes rather
than focusing on a single environmental attribute, such as recovered material
content.
• It includes unique features, including price differentials, that provide incentives
for the contractor to continually search for and use products with minimal envi-
ronmental impacts.
• It relies on consumer-market dynamics rather than government requirements to
increase the use of products with multiple environmental attributes.
• It is very flexible and allows the government or the contractor, with government
approval, to introduce new products or processes with new or improved environ-
mental performance.
Environmentally preferable products are "products and services
[that] have a lesser or reduced effect on human health and the
environment when compared to other products and services that serve the
same purpose."
— Executive Order 12873, Federal Acquisition, Recycling, and Waste Prevention
October 20, 1993
The DOD contract
is one of the first
contracts to
incorporate
environmentally
preferable
purchasing.
-------
This case study details DOD's successful attempt to adopt environmentally prefer-
able purchasing practices as directed by Executive Order 12873, Federal Acquisition,
Recycling, and Waste Prevention. It explains how DOD incorporated the seven
guiding principles outlined in the U.S. Environmental Protection Agency's (EPA's)
proposed Guidance on Acquisition of Environmentally Preferable Products and
Services. It also illustrates how environmental preferability can be incorporated into
the contracting process while continuing to meet or exceed existing performance and
price objectives.
Project History
Background
On May 31, 1995, DOD, along with die General Services Administration and the
National Aeronautics and Space Administration, issued an interim rule to incorporate
environmental factors into purchasing, based on directions provided in Executive
Order 128731. At that time, DOD's Washington Headquarters' Service Office began
searching for an appropriate project in which to introduce the new process.
EPA's Environmentally Preferable Guidance
EPA identified seven guiding principles to help federal agencies incorporate
environmental preferability into their procurement practices. These principles
were proposed in the Federal Register (FR) in EPA's Guidance on Acquisition of
Environmentally Preferable Products and Services (60 FR 50722):
1) Consideration of environmental preferability should begin early in the
acqiiisition process and be rooted in the ethic of pollution prevention,
which strives to eliminate or reduce, up front, potential risks to human
health and the environment.
2) A product or service's environmental preferability is a function of multiple
attributes.
3) Environmental preferability should reflect the lifecycle considerations of
products and services to die extent feasible.
4) Environmental preferability should consider die scale (global versus local)
and temporal reversibility aspects of a product or service's impact.
5) Environmental preferability should be tailored to local conditions where
appropriate.
6) Environmental objectives of products or sen-ices should be a factor or sub-
factor in competition among vendors, when appropriate.
7) Agencies need to examine product attribute claims carefully.
See the Federal Register, volume 60, number 104, Ma)- 31, 1995, pages 28,494 to 28,500.
-------
As directed by Executive Order 12873, EPA issued draft guidance on September
29, 1995 identifying seven guiding principles to help federal agencies incorporate
environmental preferability into dieir procurement practices. Around that same time,
DOD identified a need to issue a contract to repair and maintain the access roads and
parking lots at the Pentagon and at three other Washington, DC, area facilities.
DOD decided this contract would be the first to incorporate the new environmentally
preferable purchasing principles.
DOD contacted EPA hoping to obtain a list of environmentally preferable prod-
ucts similar to the lists of recovered material (recycled) content products identified in
die Comprehensive Procurement Guidelines.2 After learning that no such list exists,
because the attributes to define such products can differ from region to region, pro-
ject to project, and product to product, DOD attempted to use lifecycle concepts1 to
identify products with environmental attributes appropriate for its needs. Most of the
available information on lifecycle assessments, however, was too theoretical to incor-
porate or was focused on products and processes unrelated to DOD's parking lot
repair and renovation needs.
DOD contacted EPA's Environmentally Preferable Purchasing (EPP) program for
assistance. EPP volunteered to help DOD identify' the appropriate attributes and
suggested turning die project into an environmentally preferable purchasing pilot
project. DOD agreed, and the results of this joint pilot project are described below.
Project Scope
The Pentagon is one of die world's largest office buildings, containing close to
three times the floor space (by square foot) of the Empire State Building. It provides
office space for approximately 29,000 military and civilian employees and over 67
acres of parking in 16 parking lots for 8,770 vehicles. The Pentagon Reservation also
includes 10 miles of access roads and five bridges and overpasses.
DOD contacted
EPA for
assistance.
EPA is required under section 6002(e) of the Resource Conservation and Recovery Act (RCRA) to designate items that
can be made with recovered materials and to recommend practices to assist federal agencies in procuring those items.
RCRA also requires that federal agencies, when purchasing designated items, purchase them containing the highest
percentage of recovered materials available.
As required in Executive Order 1 2875. EPA identifies designated products in the Comprehensive Procurement
Guidelines, which is published in the Federal Register. EPA recommends recovered material content percentages for
each of the products it designates in an accompanying Recovered Materials Advisory Notice. As of June 1997, EPA
had designated 24 products in seven product categories.
" A product's life cycle includes all steps necessary to produce, transport, install, maintain, and dispose of, recycle, or
reuse the product. A lifecycle assessment (LG\) is a process for evaluating the environmental burdens associated with
a product. LCAs identify and quantify the energy and material uses and releases to the environment and cover the
entire life cycle of the product, including extracting and processing the raw materials; manufacturing, transporting, and
distributing the product; product installation, use, reuse, and maintenance; recycling; and final disposition.
-------
The contract
includes repairs
and maintenance
for over 12,000
parking spaces.
In addition to the Pentagon's
access roads and parking lots, the
DOD parking lot repair and main-
tenance contract also covers an
additional 3,000 parking spaces,
and their accompanying access
roads, at three nearby DOD facili-
ties: the Military Court of Appeals,
the Navy Annex, and the Hybla
Valley Federal Building.
The parking lot repair contract
is a small business set-aside, indefi-
nite quantity, fixed price, task
order contract. All of the products
used are traditionally purchased by
the contractor who is awarded the
contract and not directly by DOD.
Compared with many of DOD's
contracts, the parking lot repair
DOD's parking- lot repair contractor pur-
chases the following types of materials:
• Asphalt Base and Surface Course
• Asphalt Cement
• Asphalt Sealants
• Bituminous Prime and Tack Coats
• Concrete Curing Compounds
• Concrete Drainage Pipes
• Emulsified Asphalt Slurry
• Epoxy Bonding Compounds
• Silicone Sealants
• Traffic Paint
• Traffic Signs and Posts
contract is a relatively small and
simple procurement. The contract amount was estimated at between $500,000 to $1
million per year, and the level of detail required for the contract was fairly routine.
Working closely with EPA, DOD considered several possible options for promot-
ing the use of products with multiple environmental attributes.
Developing an Environmentally Preferable Purchasing
Pilot Project
DOD and EPA created a small workgroup to outline the components of a success-
fid pilot project. The work group determined that die project should ensure that
products used to complete the parking lot repairs meet all government specifications
and requirements, are available at an affordable price, and reduce environmental and
human health impacts. The group decided it should be easy to implement and should
take into account the seven environmentally preferable purchasing principles outlined
by EPA. (See the sidebar on page 2.) They also wanted to design the project so that
the lessons learned could be easily incorporated into future construction projects.
-------
Looking for a New Approach
Traditionally, DOD uses existing product specifications from similar contracts
when preparing a new contract. While this approach saves time, it can inhibit the
introduction of innovative products and processes, including the introduction of prod-
ucts with improved environmental performance. DOD wanted an approach that was
easy to implement, but was also very flexible. Flexible product specifications are espe-
cially important for products with environmental attributes because the market for
these products is very dynamic, and new attributes and products are continually being
introduced. In addition, new information on existing attributes and products is con-
tinually being discovered.
One of the first solutions considered by die DOD and EPA team was developing a
list of approved products that must be used by the contractor to repair and maintain
die parking lots. This option was not selected because the list would require continu-
al updates in order to accurately reflect state-of-the-art product availability. The
updates would require additional resources not currendy available to continually
investigate new products and attributes.
Independent "Green" Labeling Services
The DOD and EPA team considered relying on independent labeling organiza-
tions to identify and approve products with environmental attributes, and requiring
the contractor to use "approved" products whenever possible. The team decided
against diis approach for the following reasons:
• At the time, none of the independent labeling organizations contacted by the
team had sufficient information on parking lot products.
• Companies seeking certification from independent labeling organizations can
incur significant laboratory costs and product evaluation fees to obtain approval.
The DOD and EPA team was concerned that smaller companies that manufac-
ture products with multiple environmental attributes would be unable to afford
certification, which would limit the products from which DOD could select.
DOD also considered but did not require companies to be certified under ISO
14000 or 9000 requirements for this reason.
• Most importantly, the DOD and EPA team felt diat the government needed to
make final decisions on product selection. Delegating that responsibility to an
outside firm would have unnecessarily reduced DOD's involvement in the deci-
sion making process.
Although the team did not want to automatically require or approve products that
were prescreened by an independent labeling organization, DOD has found the prod-
uct specifications developed by such organizations useful when developing other spec-
ifications. Green Seal, a nonprofit environmental labeling organization, for example,
had an existing specification for the volatile organic compound (VOC) content for
paint diat was useful in developing die environmental attribute specifications for die
paints used in another DOD construction project. As a result, paints diat meet die

-------
Green Seal stamp of approval, however, to be used on the DOD project; they must
simply meet the DOD specifications.
The DOD/EPA
team adopted a
three-step
method.
DOD's Solution
After examining all of the options, the DOD and EPA team adopted a unique
three-step method for incorporating environmental preferability into the parking lot
contract that does not include an approved product list, does not rely on outside certi-
fication, and allows the contract to be easily modified to include the latest environ-
mental attributes. First, contractors were required to include previous environmental
performance information and a plan for obtaining products with environmental
attributes in their proposals. Both of these factors were included as part of DOD's
bid evaluation process. Second, the team identified attributes that can be used to
compare the environmental preferability of products to be used under the contract.
The team did not identify all of the possible environmental attributes for every prod-
uct, but instead provided an overview of currently available ("baseline") attributes.
Third, the team developed price differentials as an incentive for the contractor to use
products that meet or exceed the baseline attributes. The contractor can also propose
to use products or construction practices with additional environmental attributes or
improved environmental performance. With DOD approval, the contractor can use
the new product or practice and is eligible to receive a price differential for doing so.
Making It Work
Once the DOD and EPA team decided to include baseline attributes in the con-
tract, they had to identify7 those attributes. This process included conducting the nec-
essary market research, analyzing the research findings and identifying the attributes,
and developing worksheets to convey the information to contractors.
Product Research
The DOD and EPA team quickly determined that it did not have the resources
available to conduct product research on ever)' item that would be needed under the
contract. Instead, it elected to focus only on the most frequently used products. The
team selected 20 product categories from approximately 40 categories. Together the
20 products represent approximately 90 percent of the materials used under the con-
tract.
Relying on publicly available information sources, such as the Recycled Products
Guide, Harris Directory, Thomas Director)', and the Department of the Interior's
National Park Service Sustainable Design and Construction database4, the team iden-
tified manufacturers and suppliers for each of the product categories. Based on this
product information, the team created surveys for each of the categories to gather rel-

-------
evant information about applicable American Society for Testing and Materials speci-
fications, VOC content, and other product-specific environmental attributes, as well
as to request copies of Material Safety Data Sheets (MSDSs)/ The surveys also
included copies of the operational requirements for each product category and asked
respondents to identify the environ mental attributes of products meeting the require-
ments and to explain why the attributes were environmentally preferable. DOD sent
the surveys to each of the manufacturers and vendors identified by the DOD and EPA
team.
The surveys were sent directly by DOD rather than the DOD and EPA team to
clarify that DOD was seeking the information as a potential customer and to avoid
any confusion or potential concerns among the manufacturers and vendors surround-
ing EPA's participation. This also helped communicate the message that DOD was
actively seeking information on products' environmental performance as a consumer
for die purpose of making purchasing decisions and that the information was not
being collected for regulatory reasons.
Research included
obtaining publicly
available
information and
conducting a
product survey.
Identifying the Environmental Attributes
After compiling the survey results, the DOD and EPA team examined product
information for each of the 20 product categories to ensure that the available products
met the following minimum requirements:
• Achieved DOD's performance requirements.
• Available at an affordable price.
• Achieved all industry standards; local codes; and pertinent federal, local, and
state regulations.
• Offered adequate competition.
Based on the available information, the DOD and EPA team compiled a list of
appropriate environmental attributes for 11 of the 20 product categories. The team
was unwilling to select environmental attributes for the remaining nine categories due
to insufficient information. Due to the inherent flexibility of the contract, however,
the contractor, based on an emerging technology or their market research, can sug-
gest additional attributes, products, or processes for any of the product categories, not
just the original 20 investigated by the DOD and EPA team. The contractor is eligi-
ble to receive a price differential for identifying a new attribute, product, or process if
DOD permits its use on the project. (See "Contractor Incentives" below.)
The team identified
attributes for 11
product categories
1 MSDSs identify any hazardous or toxic materials used in a product and outline proper product safety precautions
along with fire and explosion, reactivity, and other safety risks. MSDSs are not required for all products, and the
type of required information contained can differ from product to product. As a result, it is difficult to compare
products based solely on MSDS information.
-------
DOD's Product Worksheets
The team
developed
worksheets to
identify the
environmental
attributes.
The following list identifies the 20 products for which DOD furnished
worksheets. The list can be expanded by DOD or, with DOD's approval, by
the contractor to include any product or service associated with die contract:

.Asphalt Cement
Indicates that the worksheet identified specific environments] performance attributes at the time the contract
was awarded. The contractor can suggest additional attributes for any product or process used to complete
work under die contract.
Product Worksheets
The DOD and EPA team prepared 20 product-specific worksheets to make it easi-
er for the contractor to identify the operational and performance requirements for
each product. The worksheets also identify the environmental performance attributes
(price differential requirements) for the 11 products for which they were developed.
The contractor is required to submit completed worksheets and any necessary sup-
porting data so DOD can certify that the products used to complete the work comply
with all of the appropriate operational and performance specifications and can deter-
mine whether the product improves environmental performance. (See the appendix
for copies of the worksheets.)
Contractor Incentives
The DOD and EPA team determined it would not be sufficient simply to encour-
age the contractor to use products meeting the environmental criteria identified on
the worksheets. Instead, they decided it was necessary to provide incentives for the
contractor to continue to search for products with environmental attributes exceeding
those described on the worksheets and to propose new products, attributes, and
processes.
8
-------
The team devised incentives for two phases of the contractual process—one prior
to and one following the award of die contract. The first incentive required each
contractor bidding on the contract to submit a proposed approach for identifying,
obtaining, and evaluating environmentally preferable products as part of their pro-
posed management plan.
Each contractor's environmentally preferable purchasing plan was evaluated as part
of its technical evaluation score. A contractor could obtain higher technical perfor-
mance scores and increase its likelihood of winning die contract by demonstrating
experience or familiarity with environmentally preferable purchasing practices in its
proposal.
Contractors also could increase their overall score if their past performance on sim-
ilar projects demonstrated a propensity for environmental stewardship. Evidence of
environmental stewardship might include onsite recycling or the selection of products
based on environmental considerations.
Price Differentials
The contract includes a price differential to encourage die contractor to continue
searching for products widi improved environmental performance. The price differ-
ential allows the contractor to earn additional money for identifying and using prod-
ucts with additional environmental attributes. The price differential is based on die
number of environmental attributes for the products used to complete each line item
in the contract. Each line item includes specific activities related to particular aspects
of parking lot maintenance and repair.
There is, for example, a separate line item for each of die following five activities:
providing 4-inches of asphalt base course, providing 2- to 4-inches of asphalt surface
course, removing existing signs and posts, painting new traffic lines, and installing
new road sign posts. The parking lot contract includes 147 line items in 45 cate-
gories.
Work is issued to the contractor through task orders specifying a line item or list of
line items to be completed. A single task order, for example, might include line items
directing the contractor to remove existing traffic posts and signs from a designated
section of the parking lot, remove the existing asphalt, increase the height of the
utility covers, repave the designated section with new asphalt, repaint the parking lot
lines, and install new traffic posts and signs.
Although the contractor agrees to a fixed price for each line item, die contractor
can earn up to a 10 percent price differential per line item by using products with
multiple environmental attributes. The price differential is computed based on the
attribute information provided on the contract worksheets. (See the appendix for
copies of the worksheets.)
The contractor
can earn a price
differential for
using
environmental
products.
-------
The contract
limits the price
differential to 5
percent of a
task order.
The 20 product worksheets include mandatory operational requirements and 11 of
the 20 contain optional environmental attribute (price differential) requirements.
Every product used to complete work under die contract must meet all operational
requirements. The contracting firm is not required to use products that meet the
environmental attributes, but is entitled to a 2 percent price differential for each
attribute if it does. The contractor can also suggest new environmental attributes for
any product used under the contract and, pending approval of die DOD Contracting
Officer's Representative, the contractor is eligible to receive a price differential for
incorporating the new attribute.
The contract, however, establishes a limit of five price differentials per line item to
limit the total price differential to 10 percent per line item. The contract also impos-
es an overall price differential ceiling of 5 percent for each task order. For example,
even if a contractor earned the maximum price differential of 10 percent for every line
item in a $10,000 task order, the contract limits the total price differential for die task
order to 5 percent ($500).
The DOD and EPA team determined that 5 percent of the total task order price
was the maximum the government could provide as a price differential. They estab-
lished this limit based on a scenario in which die contractor earned a price differential
for every task order. In that scenario, DOD's available budget would only support a 5
percent price differential.
For additional information, please consult the "Computing die Price Differential"
box on page 12.
Raising the Standards
The contract allows DOD to modify the mandatory operational requirements and
voluntary environmental attributes at any time. This allows DOD to raise a product's
environmental standards by moving an attribute from the voluntary to the mandatory
category. The contractor is required to provide products tiiat meet all mandatory
requirements and is not eligible for a price differential for doing so.
DOD is expecting to use this option as environmental attributes become industry
standard product attributes. For example, the contractor currently can receive a price
differential for using paints with a VOC content less than 150 grams per liter. If
paints ever routinely obtain this level, however, DOD might make this attribute a
mandatory rather than voluntary requirement
DOD can also introduce new environmental attributes at any time. Doing so pro-
vides the contractor with an incentive to increase the environmental performance of
the products they choose to use by creating an additional price differential opportuni-
ty. This provides DOD with an effective mechanism for encouraging the contractor
to continually search for products with additional environmental attributes.
10
-------
The contractor, as discussed previously, can also suggest new environmental attrib-
utes at any time. After obtaining DOD approval, the contractor is eligible to receive
a price differential each time a product incorporating the attribute is used. This pro-
vides the contractor with additional incentives to identify new products and attributes
and improve overall environmental performance throughout the duration of the con-
tract.
Both DOD and the
contractor can
introduce new
environmental
attributes.
Why Price Differentials?
Price differentials were included in the contract for several reasons. The contract
is a small business set-aside contract, and the DOD and EPA team recognized that
the contractors bidding on the contract were not likely to have an overhead budget
large enough to absorb the cost of identifying and procuring products with multiple
environmental attributes. The price differentials were included to provide an incen-
tive for the contracting firm to complete the necessary research and to compensate it
for doing so.
The DOD and EPA team recognized, however, that price differentials are not
always a viable option. While DOD will be using products with reduced environ-
mental impacts in another upcoming multimillion-dollar Pentagon renovation con-
tract, it does not expect to use price differentials for three reasons. First, a 5 percent
price differential on a multimillion-dollar contract is significantly larger than a 5 per-
cent price differential on a $1 million per year contract. DOD does not feel it can
justify or afford the additional expense.
Second, die contractors likely7 to submit proposals on the larger Pentagon renova-
tion contracts are larger companies that are more likely to have overhead budgets that
allow them to invest the time necessary to identify and procure products with envi-
ronmentally beneficial attributes. They are also more likely to have existing environ-
mental expertise. DOD believes the primary motivation for larger contractors to
adopt environmentally preferable practices is their ability to use their involvement
with a large-scale federal environmentally preferable purchasing project as a market-
ing tool to win future contracts.
Third, the use of products with improved environmental performance will be part
of the contractor's annual performance evaluation. A poor performance evaluation
can negatively affect the contractor's ability to obtain new government contracts.
DOD feels that including the use of products with environmental attributes in a con-
tractor's performance evaluation will be a sufficient incentive for contractors.
Price differentials
are not always a
viable option.
11
-------
Computing the Price Differential
Like man}? government contracts, work under DOD's parking lot repair and maintenance contract
is assigned by issuing task orders. Each task order contains a list of individual line items, each of
which identifies a specific activity to be completed by die contractor, die number of times that activity
can be completed under the task order, and die price the contractor will be paid for completing it.
In the sample task order on the right, the first line item requests die contractor to remove up to
280 tons of deteriorated asphalt concrete and to recompact the subbase. The contractor will be paid
$71 for each ton of asphalt removed for a total of up to $19,880 to complete the line item. The for-
mula for computing the price a contractor will be paid for completing each line item is:
Line Item Price = Quantity Completed x Price
Unlike traditional task orders, the contractor working under DOD's parking lot repair contract can
increase the price they are paid for completing each line item by incorporating DOD-approved envi-
ronmental attributes. The environmental attributes are identified on the product worksheets that the
contractor completes and provides to DOD before initiating work on a task order. (See the appendix
for copies of the worksheets.) As described in the case study, the contractor can propose new envi-
ronmental attributes for any line item and can modify or create worksheets to identify' the new attrib-
utes.
The contractor can earn a two percent price differential for each environmental attribute incorpo-
rated in completing a line item. In the adjacent sample task order, the contractor is planning to use a
product with a single environmental attribute when installing the parking lot stall lines. Doing so can
earn the contractor an additional $154.66, which is two percent of the maximum line item price of
$7,733. The formula for computing the price differential for each line item is:
Price Differential = Number of Environmental Attributes x 0.02 x Line Item Price
The total amount die contractor is paid is calculated by computing the value of each line item,
including any price differentials earned, using the formulas described above. In this example, the
contractor has the potential to earn up to $161,586.69, including $298.44 in price differentials.
Restrictions
The DOD parking lot contract establishes two restrictions to prevent the price differential from
becoming prohibitively expensive for die government:
• No line item can include more than five environmental attributes. This limits each line item's
maximum price differential to 10 percent.
• The total price differentials cannot exceed 5 percent for any task order.
For additional information on these restrictions, see "Price Differentials" on page 9.

t For this line item, the contractor proposed using a paint with a single environmental attribute—a VOC content of less than 100 grams per liter. As
stated on the product worksheets (provided in the appendix), paints with a VOC content of less than 150 grams per liter are eligible for a price
differential. In this example, the contractor has already received permission from DOD to use die low VOC paint and DOD has agreed to provide a
price differential.

Advantages to DOD's Approach
T
he way in which DOD incorporated environmentally preferable purchasing
principles into the parking lot maintenance and repair contract reveals several
advantages.
Continual Improvement
The flexible contract design allows the government to continually improve the
baseline for measuring die environmental preferability of a product. This helps
ensure that the government is aware of products with the highest number of environ-
mental attributes. As new products that provide improved environmental perfor-
mance are introduced, they can lie easily integrated by DOD and its contractor if they
meet DOD's other operational and performance requirements.
Contract Flexibility
The environmentally preferable clauses in the contract were developed as "add-
ons." The clauses are clearly identified in the contract and not buried within the con-
tract language. They are specifically designed to be easily modified. The framework
can be easily adapted for use in other DOD or federal contracts and can be easily
removed if, for any reason, it becomes necessary to do so.
Shared Responsibility
The responsibility for incorporating products with environmental attributes is
shared between the contractor and the government. The contractor's role is to inves-
tigate the availability and performance of products with multiple environmental
attributes and bring them to the government's attention. The government's primary
role is to establish the baseline for measuring improvement in environmental perfor-
mance and to evaluate the products proposed by the contractor to determine if they
warrant a price differential.
Market-Driven
DOD is not developing unique specifications for products that only they will use.
It is simply expressing a desire to purchase products with multiple environmental
attributes as they become available. This approach relies on the dynamics of the mar-
ketplace, including competitive pricing and the ability to select the most appropriate
product from among multiple options.
14
-------
Works Within Existing Procurement Procedures
None of the standard DOD contract award procedures were modified to incorpo-
rate environmentally preferable purchasing. The evaluation procedures used to award
the parking lot repair and maintenance contract were identical to those used for pre-
vious contracts. The environmentally preferable evaluation criteria contained in die
Request for Proposal (RFP) were examined along with the more traditional technical
aspects, such as demonstrated experience and performance.
Current Status and Future Steps
The parking lot repair and maintenance contract was awarded on June 4, 1997,
to D-M&S Inc., a Woodstock, Maryland contractor. The first Task Order was
issued in September 1997. In less than a month, D-M&S Inc. had already
identified several products with additional environmental attributes and a new
environmentally superior process, all of which appear to significantly improve envi-
ronmental performance while continuing to meet or exceed DOD's performance
criteria. The contractor is very pleased witii the process for incorporating products
widi additional environmental attributes and is excited at the possibility of earning a
price differential for doing so. The success of die environmentally preferable contract
clauses will be continually monitored throughout the contract's 5-year period of
performance.
DOD is currently considering ways to incorporate environmentally preferable pur-
chasing into a contracting vehicle for the Pentagon's 15- to 20-year renovation effort.
Future case studies will document this work.
Lessons Learned
The DOD parking lot repair and maintenance contract is one of the first
attempts by a federal agency to provide contractors with an incentive to incor-
porate environmentally preferable purchasing under Executive Order 12873.
As a result, many of the lessons learned from this process can help guide future
attempts. The following are highlights of some of the most important lessons
learned.
Environmentally Preferable Purchasing Can Be
Successfully Incorporated Into the Contracting Process
DOD's contract has successfully integrated environmentally preferable purchasing
priorities within several phases of the contracting process—the development of the
RFP, evaluation of contractor proposals, contract award, contract startup, and contract
operation. The DOD and EPA team will continue to evaluate the success of this
approach during the contract's 5-year period of performance.
15
-------
Market Research Takes Time
Market research for this project was time-consuming, despite the relatively small
number of products examined, because many manufacturers and vendors did not have
information on the environmental attributes of their products. This problem should
be alleviated as the demand for products with multiple environmental attributes
increases and manufacturers and vendors respond by identifying the environmental
attributes of their products. Until that time, market research can be contracted out if
adequate funding is available. Alternatively, it can be reduced by limiting die initial
research to a few select product categories.
DOD recently contracted a market research firm to collect information on the
environmental impacts of construction products. DOD is currently reviewing the
information for possible use during the 15- to 20-year, multimillion-dollar Pentagon
renovation. EPA will be publishing future case studies documenting these efforts.
It is important to note, however, that market research might not be necessary for
all projects. There are an increasing number of publicly available databases that con-
tain information on the environmental attributes of a wide variety of products. These
databases will help government agencies select products without requiring agencies to
conduct independent market research, which can be very time consuming and expen-
sive. It is also likely that as the demand for products with improved environmental
performance increases, many manufacturers will begin identifying the environmental-
ly preferable aspects of their products in product literature.
Draft RFPs Are Not Always Necessary
DOD published a draft RFP in July 1996 to allow contractors an opportunity to
comment on DOD's proposed approach for incorporating environmentally preferable
purchasing. While draft RFPs are beneficial in some situations, DOD did not receive
any comments, with the exception of a single comment addressing a portion of the
contract unrelated to environmentally preferable purchasing.
After talking with potential small business set-aside contractors, DOD concluded
that die level of effort required to respond to a draft RFP exceeds what contractors
are willing to invest without compensation. Contractors devote resources to RFPs in
proportion to the value of the contract. Since draft RFPs do not provide contractors
with any financial reward, they are not likely to produce helpful responses. The actu-
al RFP was released in December 1996 and did not contain any modifications to the
environmentally preferable purchasing language published in the draft RFP.
DOD contracting officials now believe that draft RFPs are more likely to be
helpful when the contracts are large and the number of potential contractors is
small. This will provide contractors with an opportunity to ask DOD to clarify
selected portions, which will result in more detailed contractor proposals that are
easier to evaluate.
16
-------
Interagency Teamwork Works
DOD and EPA demonstrated the advantage of working together to incorporate environmentally
preferable purchasing into DOD's contractual procedures. DOD was instrumental in initiating the pro-
ject and in defining the project goals and boundaries. EPA worked closely with DOD to identify and
examine the environmental attributes associated with parking lot maintenance and repair work.
Together, they developed a unique approach that met Executive Order 12873's directive that federal
agencies incorporate environmentally preferable purchasing.
