Introduction
A. Background on Residential Demolitions
The United States Environmental Protection
Agency (U.S. EPA) Region 5 has recognized the
challenge that vacant residential properties pose to
communities throughout U.S. EPA Region 5
office, which includes the states of Indiana,
Illinois, Michigan, Minnesota, Ohio, and Wisconsin.
Residential demolitions
are taking place at a
record pace as cities
attempt to reduce
the existing backlog
of vacant buildings,
and improve
neighborhood
conditions affected
by population loss
and the foreclosure
crisis.
Region 5 has developed this report and
the bid specification development tools based on
the experience and knowledge of Region 5 staff and
representatives of communities in Region 5.
In recent years, the number of vacant, dilapidated,
and abandoned residences has increased dramatically.
As cities have responded to stabilize the decline
in cities, demolitions of residences have become a
common practice to remove the hazard that vacant
properties pose to surrounding communities.

B. Current State of Residential Demolitions
Current residential demolition programs vary
greatly across the region. Cities, counties, sewer
districts, land banks, and other entities may all
have demolition programs operating jointly or
separately within their respective jurisdictions.
A high degree of variability exists in the
demolition practices on sites, which contributes
to uncertainty in future reuse of vacant parcels.
There may also be communities currently
without land banks or other entities that
operate demolition programs. New entities
will emerge to meet the demand for residential
demolition and neighborhood stabilization.
Current demolition
practices may leave an
unfortunate legacy of
land contamination
when house debris is
used as fill material
as part of the current
demolition process.
There are significant
environmental, liability,
and redevelopment
issues with this
demolition practice.
-------
As a response to the current state of demolition practices, this
document provides organizations conducting demolitions with
bid specification development tools that could be used during
the local procurement process. These tools (Appendix) will
allow cities, counties, land banks and other organizations to
develop higher quality contract language that can be inserted
into their own existing bid specification documents The overall
goal is a demolition process that is better for the environment.
C. Overview of U.S. EPA Bid Specification Development Tool Project and Project Goals
Region 5 developed this user report, which includes a menu of bid specification development tools, for
use by cities, counties, land banks, and other entities engaged in residential demolition operations to
yield an improved environment result. The bid specification development tools found in the
appendices of this document have been designed to serve more than one purpose. They can serve as a
tool to help the reader anticipate the environmental issues and concerns that may arise in connection
with a demolition project so that those issues and concerns can be factored into the planning process.
They can help the reader develop and organize information concerning a demolition project. They can
also be used to modify existing bid specification language used by a community or to assist in
creating language for new bid specifications. This specification language could then be utilized to
develop procurement language, contract language, and associated documents, as appropriate, for use in
a specific bid package that would instruct contractors on the contract and on the general and the
technical requirements for the demolition project.
Some of the provisions included in the bid specification tools are based on regulatory requirements.
Regulatory requirements exist irrespective of whether they are included in a bid specification, and
the potential specifications included in the bid specification tools do not include an exhaustive list
of applicable regulatory requirements. Such an exhaustive list cannot be provided because regulatory
requirements may vary depending on the particular facts of the demolition project being planned
and performed. The municipality or other entity planning and bidding the demolition project, and the
contractors involved in the process, are responsible for determining and consulting the relevant
regulatory requirements; including those cited in the reference section of the individual bid
specification development tools found in the appendices of this report.
Also included in the bid specification development tools are some potential provisions that are not
required by regulation, but rather, are suggestions for municipalities and other entities to consider
when developing bid specifications and contracts for residential demolitions. These recommended
provisions are written as they might appear in a municipality's bid specification documents and thus
are framed in mandatory language. This mandatory language is not meant to imply the existence,
creation, or reinterpretation of any regulatory requirement. This bid specification development tool
is not creating any new regulatory requirements or changing any existing regulatory requirements. The
provisions that are not based on regulatory requirements represent best practices and are tools
available to the municipality to consider while developing bid specifications and contracts.
o
By providing cities, counties, land banks, and other entities with these bid specification development
tools, it is anticipated that demolition site conditions at the conclusion of the demolition process will
be better than they would have been without the implementation of these tools. Looking ahead, cities, -=
counties, land banks, and other entities that have increased certainty of the site conditions may be able
to more effectively reuse or market sites that will consistently meet the needs of end users.
-------
The goal of the residential demolition bid specification
development tools (see Appendix) is to assist cities,
counties, land banks and other organizations to
improve residential demolitions. Benefits that
communities may achieve include:
• Improved stormwater infiltration.
• Reduced stormwater runoff.
• Greater adherence to environmental regulations.
• Improved worker safety.
• Maximized diversion of waste from landfills by
increasing salvage and recycling.
• Proper handling of hazardous waste streams.
• Improved end-use aesthetics.
• Stabilized and revitalized neighborhoods.
This report can assist cities, counties, land
banks and other organizations in avoiding
specific negative impacts of poorly planned
and implemented residential demolitions.
One goal of this report is to help reduce
impacts to air pollution, water pollution,
and improperly managed hazardous
waste. It may also be used to help achieve
other environmental goals such as better
stormwater management, habitat creation
for insects and native plant species, as
well as help reduce the amount of waste
materials that go to landfills.
The areas with the potential to provide increased
environmental benefits were identified through
environmental interviews with stakeholders
located throughout Region 5 (see Section 5).
Results of the interviews helped clarify the most
achievable areas of improved environmental
performance through the demolition process. Given the wide range of entities, employed methods,
levels of experience, funding, demand, and geographic spacing, these specifications are intentionally
broad and generic in nature, so as to be useful to as many entities as possible, while still
accomplishing the goal of improving the environmental performance of demolition practices.
Included in the Appendix are bid specification development tools for demolition projects, which reflect
goals of preventing adverse environmental and health impacts. The desired environmental outcomes
include improving stormwater infiltration, reducing the potential for adverse environmental impacts,
ensuring compliance with asbestos requirements, and leaving the sites in a condition suitable for
redevelopment, including green infrastructure and community agriculture uses. This report is designed
to provide an explanation of the goals, intents, and process of development of the bid specification
development tools in the Appendix. Also included in the demolition bid specification development
tools is a list of existing regulations and best management practices that relate to building demolition
procedures.

Green infrastructure is an approach that communities can choose to maintain healthy waters,
provide multiple environmental benefits and support sustainable communities. Unlike single-
purpose gray stormwater infrastructure, which uses pipes to dispose of rainwater, green
infrastructure uses vegetation and soil to manage rainwater where it falls. By weaving natural
processes into the built environment, green infrastructure provides not only stormwater
management, but also flood mitigation, air quality management, and much more.

D. Evaluating Value - Short and Long Term Implications
Direct project costs (materials, labor, equipment, etc,) are commonly the primary factor considered
when designing a residential demolition project. Managing a projects direct cost and developing a
direct cost baseline or budget for a project and/or a demolition operation is critical to successful project
management. However success can often be impacted by other factors beyond the cost of the immediate
investment to demolish a residential structure. Successful demolition projects and/or demolition
operations require the ability to consider other key factors in order to ensure that a project provides value
to the community by positively impacting a wide range of economic, social, and environmental benefits.
Within Section 3 of this report, (Highlighted Demolition Modifications to Improve Environmental
Results), the reader will find the following subtopics: Environmental Impacts, Operational Impacts,
Liability and Risk Reduction Impacts, and Cost Impacts. The subsections do not represent an exhaustive
list of factors beyond direct costs that should be considered nor do the narrative sections represent a
conclusive discussion of the individual impacts. These subsections have been designed to encourage
critical thinking on other factors that may be overlooked when making decisions based solely on the
direct costs of demolishing residential structures.
Many cities are exploring urban farming, creating stormwater
retention infrastructure, waterfront parks, open space, habitat
creation, urban forests, and other environmentally beneficial
ways to use vacant land. However, current demolition
practices that allow substantial impervious surfaces to
remain (driveways, foundations, parking areas, etc.) do
not adequately prepare vacant parcels for these reuses.
Left in place, these impervious surfaces inhibit stormwater
infiltration and become obstacles to the reuse of the property
through imposed costs on the next developer.
E. Stabilizing Communities through Improved Demolition Practices
Many communities are contemplating large-scale demolition of abandoned residential structures in
an effort to stabilize the housing market in affected neighborhoods. Unfortunately, the destabilizing
impact of abandoned residential structures may continue even after the residential building structure
is demolished. For example, poorly maintained vacant lots may become targets for illegal dumping of
construction waste, hazardous materials, and garbage.
To address this continuing nuisance, communities are repurposing and redeveloping vacant lots. This
report highlights technical features in the demolition process that can expedite local stabilization
strategies through better site preparation for eventual reuse. If current demolition practices were
improved and coordinated with other community strategies and initiatives, the demolition activity
could potentially assist communities in the transformation of vacant properties into amenities and
opportunities. These activities could add value to a neighborhood and improve the quality of life of the
local residents.

Enhanced demolition practices can achieve
multiple environmental goals and set the stage
for vacant lot revitalization. The use of these
bid specification development tools may lead
to improved revitalization outcomes for local
communities as demolition practices better
prepare sites for greener reuse, such as the
community garden pictured on right.
Improved demolition practices will help cities, counties,
land banks and other entities stabilize property values
by leaving vacant lots in a more aesthetically pleasing
condition and provide developers with a standardized
vacant property ready for reuse. In the image on left,
a recent demolition (Lot A) will need additional soil
and stabilization measures to avoid becoming another
empty lot that is devoid of all vegetation (Lot B).
F. Health and Safety Disclaimer
Although this document addresses briefly the topic of worker health and safety and public safety and security
at residential demolition sites, it is not the focus of this document. The user should ensure that any residential
demolition is conducted in accordance with all applicable health and safety provisions of Title 29 and Title
40 of the Code of Federal Regulations, as well as all applicable federal, state and local requirements. One best
practice would be to develop a health and safety plan for the project which establishes personnel protection
standards and mandatory safety practices and procedures that protect both workers and the general public.
Additionally, the health and safety plan assigns responsibilities, establishes standard operating procedures,
and describes how unplanned events and incidents will be handled. Additional information on this topic is
widely available and the reader should research available information and contact local resources to ensure
compliance with applicable regulations to provide a safe and secure work site.

2. Environmental Conceri
about Common
Demolition Practices
There are several areas in which
improvements can be made to existing
demolition practices in order to increase the
environmental quality of the end result. The sheer
scope of this issue is staggering: 250,000 housing units
and 45,000 non-residential structures are thought to be
demolished in the United States each year - as measured before
the arrival of the foreclosure crisis (Franklin-Associates, 1998).
Considering the effects of the foreclosure crisis and loss of manufacturing
jobs in traditionally industrial cities, this figure is anticipated to be much higher
because the demand for demolitions rises as the number of vacant housing units grows.
The most recent Census found that the vacant housing units grew by 44% from 2000 to 2010. Calculations of
demolition demand in the eight largest cities in Ohio conservatively estimate over 40,000 potential demolitions
over the next five years in those cities alone (Mallach 2012). Estimates for demolitions (US EPA, 2009) debris
generation include 19 million tons generated from residential demolitions and 65 million tons from non-
residential demolitions. This is a little more than 50 percent of all of the building-related construction and
demolition (C&D) materials generated (total of 170 million tons). Enhanced demolition practices can help
achieve multiple environmental goals and may set the stage for vacant lot revitalization. The use of these bid
specifications may lead to improved revitalization outcomes for a city, county, land bank, or other entity as
demolition practices better prepare sites for reuse.
The environmental concerns and practices discussed in this section are not applicable to all demolitions at
all locations. However, improvements in the way these concerns are addressed were identified by the various
stakeholders as having the greatest environmental benefit at residential demolition projects. As such, the
Appendix contains a menu of environmentally sensitive
practices that can easily be achievable and incorporated
into a city, county, land bank or other entity's demolition
bid specification.
Land reuse issues emerge when cities choose to fill the
basement excavation with the demolition debris itself.
This common demolition practice leaves sites in poor
condition for future
reuse. While this
practice may save
operational costs,
it has cost impacts
to future users
and the existing
neighborhood.
These indirect
costs far outweigh
the operational
savings from dropping the house into the basement and it
is recommended that cities instead use proper backfill soils.
Working with our stakeholders, we identified these issues to
be pressing concerns in current demolition practices.
A. Backfill Quality
When a home is demolished there is often a depression
or hole left behind that must be filled. The backfill soils
that have been used have been inconsistent in nature.
An outdated and inadequate demolition practice
involves filling the site with the demolition debris
itself and/or using low quality soil. Sources of backfill
soil may not be free of contaminants or may have high
clay contents that inhibit the infiltration of stormwater.
Some backfills may contain rocks, broken concrete, or
other deleterious material that leaves sites in a poor
condition for future reuse.

B. Grading
Post-demolition site finishing practices will involve
grading the soil to ensure a level base for the entire
site. Typical grading requirements focus on
preventing settlement and ponding water. A grading
plan may also identify a specified slope for drainage
purposes. While these are essential and worthy
goals, simply matching existing grades at a site may
not reduce the risk for erosion, sedimentation,
and runoff into streets and storm sewers.
Improved demolition bid specifications
may help cities, counties, land banks and
other organizations to leave the property in
a condition that would
enhance water infiltration
and provide soil as a
growing media. The
demonstration site above
is a field test of native
plantings in a vacant lot in
Cleveland.

C. Over-Compaction
Urban sites often have soils that are greatly
compacted and do not allow for stormwater
infiltration. Compacted soil is a limiting factor in
plant establishment and growth. This can be
exacerbated by demolition and backfill methods that
further compact existing onsite soils and backfill. For
example, the use of heavy machinery in the final
stages of demolition will pack down the soil, which
results in a compacted site.
D. Vegetation
Some residential demolition programs do not
require the establishment of vegetation as a site finish.
This can lead to increased erosion and sediment
transport to the sewer system. Bare properties are also
susceptible to illegal dumping of wastes, vandalism,
and errant parking, in addition to be being a
neighborhood eyesore. Poor demolition practices
result in blighted vacant lots that also impact market
value similar to the deleterious impact of a vacant
building. These negative lasting impacts continue to
burden the environment as well as social and
economic conditions in neighborhoods.
E. Site Finishes Maintenance
Vegetation establishment may not
always be successful if contractors are not required
to protect the seed and, if resources are not available,
to maintain the greenspace. In addition to controlling
dust, sites with grass can serve as a barrier to soil
containing lead and other contaminants on sites.
Cost avoidance can be achieved by preventing the
need for sites to be refinished a second time or
requiring additional greening by third party agencies.
Demolition activities often leave soils in a compacted
state by the use of heavy
machinery that packs
down the soil. This
compacted condition
is exacerbated by poor
quality fill material,
which is often unsuitable
for getting the lot ready
for more productive uses.
While the vacant
house may be
removed from
the site, an empty
lot that is devoid
of vegetation
will be subject
to increased
stormwater runoff
and erosion. This issue is not only aesthetic, but can also
result in depressed property values of occupied homes that
surround the empty lot. Even a small property value impact
can be magnified when cities are dotted with vacant lots that
continue to malign neighborhoods even after the removal of
the building.
Improved demolition practices will assist in reducing
in an environmentally sound manner the number of
vacant residential
structure in a
community. Proper
site finishes can
reduce the potential
for exposure to
contamination
found in urban
communities.
Proper seeding of
a vacant lot allows grass to act as a barrier to exposure to
lead found in the soil.
-------
F. Complying with Asbestos Regulations
Insufficient knowledge of the asbestos regulations, a lack of adequate project oversight by the
owner and operator, and poor performance by contractors can result in violations of
applicable asbestos regulations. Some bid solicitors do not have bid specifications and
contract language which define a project's asbestos requirements and needs in sufficient
detail to ensure compliance with asbestos regulations. This presents the contractors, owners,
and operators with potential legal liabilities, extra
project costs, remediation costs and other
potential liabilities associated with violations of
federal, state, and local asbestos regulations. The
failure to comply with applicable asbestos
regulations could result in fines, penalties,
imprisonment, and lawsuits.
G. Worker and Public Health Protection
Cities, counties, land banks, and other
entities should write demolition bid
specification with sufficient detail to procure
the services of contractors who will safely
manage asbestos and other contaminants.
Improper handling or disposal of asbestos and other hazardous substances presents a
health and safety hazard not only to the site workers, but also to neighboring residents. This
applies to potential hazardous dust generated during the demolition process. Even after the
demolition process is complete, inadequate demolition may lead to site contamination from
lead, PCBs, mercury, or asbestos. This issue is a common concern in commercial and
industrial demolitions, but similar contamination concerns arise at residential sites, and can
also lead to public health concerns, future uncertainty in redevelopment and legal liability.
H. Waste Management
Inadequate inspections and assessments of properties can lead to the mishandling of
various waste streams. Contractor and worker training may not be sufficient to identify
unknown materials for safe and legal disposal. There needs to be greater awareness of
environmental regulations associated with different waste streams (e.g. mercury thermostats).
I. Diversion of Waste from Landfills
Typical bid specifications do not address opportunities for recycling, salvage, and building
disassembly and materials reuse. Working with recycling facilities and deconstruction
operations can lead to improved environmental outcomes and material sales may offset some
project costs.

3. Highlighted Demolition
Modifications to
Improve Environmental
Results
One of the goals of developing the
residential demolition bid specification
development tools is to assist cities, counties, land
banks and other organizationsentities in developing high
quality, detailed contract language. The sample bid specification
language is provided as a tool to help those conducting demolition
activities anticipate the scope of environmental issues relevant to
demolitions, resulting in a more environmentally-friendly demolition process.
The following sections outline the recommendations, and best management practices
that are included in the specification sections in the Appendix. It is recommended that each city,
county, land bank, or other entity assess its current practices, markets, and resources in order to
determine which, if any, modifications will have the greatest impact and are most feasible. When
the specifications reference demolition requirements, waste handling and disposal regulations,
or worker protection measures U.S. EPA or the Occupational Safety and Health Administration
(OSHA), those regulations must be met whenever they apply. All applicable statutory and
regulatory requirements including environmental, workers protection, and historical preservation
requirements must be met.
A. Conduct Pre-Demolition Inspections to Identify Waste Streams

See Appendix:
Pre-demolition Survey
Waste Management Plan
One of the first steps for the demolition of a vacant home is to identify,
characterize, and quantify the potential waste streams at the site.
This may help ensure accurate bidding and the handling of the different
waste streams. The Pre-Demolition Survey bid specification development tool
provides a list of the potential waste streams that should be considered for the survey,
including asbestos-containing materials (ACM),
lead-based paint (LBP), polychlorinated biphenyls
(PCBs), mercury containing wastes (Hg),
general household wastes, and other potential
hazardous wastes. Another useful set of data to
be compiled during the survey is an inventory of
the items and materials that would be suitable for
salvage and recycling. The Waste Management
Plan specification tool provides information on

streams identified during the pre-demolition survey. This plan might be too extensive to develop for
each individual residential structure, but could also be applicable and more effective for either
a group of homes contracted together, or a general program overview that could be updated annually
and provided to contractors. Such a plan may also be applicable to disaster recovery situations
when many residential homes are damaged by disasters.
i. Environmental Impacts
Only by identifying various waste streams can the plans be established for the appropriate
handling and disposal methods, which in turn protect human health and the environment
to the greatest extent possible. Identification, separation, and removal of wastes with
hazardous components like lead or mercury will allow more of the remaining materials
(i.e., wood, bricks, flooring, etc) to be considered for reuse or recycling.
ii. Operational Impacts
The pre-demolition survey and development of the inventory should not interfere with the
actual demolition which occurs later. All of the work described in these sections should take
place prior to bidding and would therefore be conducted by an entity such as an
environmental contractor, consultant or trained government employee separate from the
demolition contractor.
iii. Liability and Risk Reduction Impacts
By putting forth the effort to identify waste streams and also the plans and procedures
for the safe and legal disposal of the waste, project owners may avoid violations of applicable
environmental and health and safety regulations. Ensuring that contractors understand and
abide by the waste management plan is essential to achieving the goals of these sections.
iv. Cost Impacts
Accurate and complete waste identification is an essential component of conducting
quality residential demolitions and should be built into the cost structure. While it will not
likely lead to short term operational cost savings, the reduction in long term liabilities,
potential fines and future development costs may prevent costly change orders and avoid
miscommunication about known hazardous materials and poor public relations with local
neighborhoods and officials.

B. Remove Asbestos-Containing Materials
See Appendix:
Asbestos NESHAP
Compliance
One of the most important requirements for all
demolitions subject to asbestos regulations, and a best practice
for all demolitions in general, is to ensure that asbestos-containing material
(ACM) is handled appropriately. The Asbestos Compliance bid specification development tool provides
a brief description of key provisions of the National Emission Standards for Hazardous Air Pollutants
(NESHAP) for asbestos. The section discusses requirements for the handling and disposal of ACM along
with best management practices for all demolitions.
i. Environmental Impacts
Asbestos is a known human carcinogen and the proper handling of ACM is essential to
protect workers and the neighboring residents from releases of asbestos fibers.
ii. Operational Impacts
Generally, asbestos abatement of regulated ACM (RACM) is required prior to proceeding
with demolition. However, under some circumstances, such as when a building is structurally
unsound and in danger of imminent collapse, it may not be safe to remove asbestos prior to
demolition. In these instances, work must comply with all applicable asbestos regulations.
It is important for all site workers to be aware of the hazards of asbestos and to respond
appropriately if unknown or suspect materials are discovered. Coordination between the
abatement contractor and the demolition contractor is essential for effective project
execution.
iii. Liability and Risk Reduction Impacts
Failure to comply with the Clean Air Act's asbestos NESHAP requirements could lead to civil
or criminal enforcement actions which may lead to fines, penalties, and imprisonment.
Actions can be brought against building owners and operators, demolition contractors, as well
as other parties involved in the project, depending on the particular circumstances.
iv. Cost Impacts
Determining if asbestos is present and how it needs to be addressed is a component of
conducting residential demolitions. Such work should be built into the cost structure for
projects. It is critical that owners and operators have a clear understanding of the asbestos
regulations and use that knowledge to issue good bid specifications and clear contract
a provisions that will limit and control costs. Costly change-work orders and costly solutions
5 for mistakes involving asbestos can be avoided to some degree by good project bid
o specifications and good contract language. Abatement and demolition practices which
minimize the generation of regulated asbestos-containing debris and waste can result in cost

savings. Sometimes, removing asbestos-containing facility components in sections and
£ disposing of them in sections can save money when compared to other acceptable asbestos
o abatement practices. Packaging multiple asbestos inspections and abatement projects
— in a single bid and contract can also result in cost savings. These cost-saving efforts may also
12 provide environmental benefits by reducing the amount of waste going to landfills.
-------
C. Prevent Fugitive Dust
See Appendix:
Managing Fugitve
Dust
The Managing Fugitive Dust
bid specification development tool discusses the need to
limit fugitive dusts generated during demolition. Also discussed in the section is the handling
of other hazardous dusts that may require special protections for workers, i.e., lead, asbestos,
PCBs, mercury. According to a recent Chicago-based housing demolition study, lead dust
presents a hazard in the form of lead poisoning in children that may be reduced with proper dust
control strategies (Mucha, Stites, Evens, MacRoy, Persky Jacobs, 2009). Fugitive dust generally
refers to particles lifted into the air by man-made and natural activities such as the movement of
soil, vehicles, equipment, demolition, and wind. Consult your local environmental agency for the
definition of fugitive dust in state and local regulations.
i. Environmental Impacts
Fugitive dust can have a negative impact on the health of residents, especially those with
respiratory illnesses.
Lead dustfall from demolition of scattered site family housing: Developing a sampling methodology
"The City of Chicago provides over 3000 demolition permits each year; this is likely an
underestimate of actual demolitions because not all demolition activities have permits. The city
requires that demolition sites be fenced and that water be used to wet the debris to minimize dust
emissions, although we observed a wide range of compliance with these requirements. A recent
survey of the US housing stock by Housing and Urban Development (HUD) shows that there are
approximately 7.4 billion ft2 of interior surfaces and 29.2 billion ft2 of exterior surfaces coated with
lead paint 1 mg/cm2 (Vojta et al., 2002). The potential impact of disturbing this large surface area of
lead-based paint is substantial. If a painted surface area of one square foot at 1 mg/cm2 is disturbed
and turned into dust, and if that dust is evenly distributed over an average 10 ftxlO ft room floor,
the resulting lead loading will be 9300 (^g/ft2, well above the existing EPA limit of 40 |^g/ft2."

ii. Operational Impacts
Control of fugitive dust is largely achieved by spraying water during demolition, a
practice which is simple to execute in an urban setting with fire hydrants in the
vicinity. Multiple hoses may be necessary for larger houses if one is not sufficient and
water trucks may be required in rural areas. Generally, water is used to control fugitive
dust during the portion of the demolition that occurs after hazardous substances
such as asbestos have been removed. However, under some cirumstances, such
as when a building is structurally unsound and in danger of imminent collapse, it may
not be safe to remove hazardous materials prior to demolition. In such instances,
wetting the facility, or a portion of the facility, during demolition may be required by
regulations to control the emission of the hazardous material from the building.
In many cases, cities, counties,
land banks and other entities
are required to accept the low
bidder, who may have little or
no experience in complying
with asbestos regulations
and control of fugitive dust.
Cities, counties, land banks
and other entities should make
certain that bid specification
documents are sufficiently
detailed so that comparable
contractor services are being
evaluated.
iii. Liability and Risk Reduction Impacts
Local regulations may have restrictions on fugitive dust emissions. Hydrant
permits are often required for water use. Also important is limiting the impact on
neighboring residents and minimizing the likelihood of complaints and health
liabilities. Citizens calling about dust emissions is one of the top complaints
received by local, state, and federal enforcement offices.
iv. Cost Impacts
Fugitive dust control is a standard procedure that should have minimal impact on the
overall project cost, but the project owner should provide field oversight to ensure
adherence to the bid specifications.

D. Salvage and Recycle More Materials;
Proper Waste Disposal
See Appendix:
Salvage and Recycling
Waste Handling and Disposal
Waste Management Plan
There are two sections in the Appendix that discuss
the treatment of waste streams identified during the pre-demolition survey. The
Recycling and Salvage bid specification development tool relates to those items
intended for reuse, resale, or recycling, and the Waste Handling and Disposal
bid specification development tool pertains to all other waste streams, including
hazardous wastes, special wastes, and non-hazardous wastes. Both of the
sections are closely interrelated to the 'Waste Management Plan's bid specification
development tool, in that the plans and procedures established in the waste
management plan need to be followed during the execution of the work.
i. Environmental Impacts
Recycling and reusing materials from residential buildings saves energy
and reduces the production of greenhouse gas emissions and other
pollutants by reducing the need to extract raw materials and ship new
materials long distances. Many urban areas also address environmental
issues in minimizing the amount of waste sent to landfills, known as the
diversion rate. Depending on local regulations, required diversion rates may
be 80 percent or higher. Alternatively, goal diversion rates can be
established during the bidding phase, which may provide an incentive to
the contractor to work with local recycling and salvage operations.
ii. Operational Impacts
An increase in the segregation of materials in preparation for salvage or recycling generally will result
in increased effort by the demolition contractor and more time required per site. However, waste
segregation does not require advanced techniques or specialized equipment. Some administrative
effort may be required prior to commencing work in order to identify potential reuse or resale markets.
iii. Liability and Risk Reduction Impacts
It is best to require documentation of all materials that are taken off-site for salvage, recycling, or disposal.
These may already be required if local regulations establish a required diversion rate. Another legal
consideration is to ensure that any hazardous materials or asbestos are appropriately addressed prior to
taking them off-site. This should be addressed in the contract language and the waste management plan.
iv. Cost Impacts
The cost impacts associated with increasing recycling and salvage may be mixed. An increase in the
amount of materials recycled and salvaged may reduce the volume and therefore the cost of
disposing of wastes, but additional time spent segregating and processing different materials on-site
may lead to increased labor costs. Depending on local market availability, all-inclusive recycling
facilities may sort and segregate a single stream of materials for recycling and thereby reduce the
added labor costs. Ultimately, the cost balance will depend on the quantity, type, and condition
of the materials present at a given site. Project owners may wish to establish progressive revenue
sharing agreements that encourage salvage and recycling by the contractor to the greatest extent
possible, the markets for the materials, and the cost of waste disposal.
Demolition debris recycling and
salvage strategies are gaining
popularity. Some cities, counties, land
banks and other organizations are
evaluating deconstruction strategies
to reuse materials and provide
local job training opportunities. A
robust Waste Management Plan is
a cornerstone to any demolition
project, but especially important
if pursuing salvage, recycling, or
deconstruction activities. If there
is a focus on material recovery
then a more specific plan, such as a
Deconstruction Plan, may also be
needed before demolition begins.

E. Incorporate Deconstruction Practices
See Appendix:
Deconstruction
Deconstruction involves
disassembling an entire building,
or portions of a building, in order
to harvest materials for direct reuse
or recycling. The Deconstruction
bid specification development tool
incorporates many of the elements discussed in
other sections and also offers best management
practices for implementing deconstruction features
into existing demolition practices.

The Milwaukee Metropolitan Sewer District (MMSD) is
demolishing 83 homes along the Kinnickinnic River as part of a
S50 million infrastructure project on floodplain and stormwater
management. MMSD demolition contractors use improved
fill materials to allow stormwater infiltration and are actually
deconstructing the buildings in the floodplain. The demolition
bid specifications identify the allowable soil materials as well as
the percent, by weight, of the houses that should be kept out of
landfills. Improved demolition practices will avoid costs later in
the project to widen the stream channel and eliminate flooding
of adjacent neighborhoods.
i. Environmental Impacts
An important environmental
benefit from recycling and reuse is the
energy and natural resource savings
from reducing the need to extract virgin
resources. As discussed with recycling and salvage, another impact of deconstruction is
the reduction of waste entering landfills, known as the diversion rate, which may be
established by local regulations or within the contract. According to a Riverdale case
study compiled for EPA by the National Association of Home Builders Research Center,
if 25 percent of homes demolished were deconstructed it could save 20 million tons
of land fill space yearly. (Center, 1997). There are positive societal impacts associated
with the operation of deconstruction material outlets, such as the ReBuilding Exchange or
Habitat for Humanity ReStores.
ii. Operational Impacts
Deconstruction is often conducted by specialized deconstruction firms and is most
successful with experienced workers skilled in the disassembly and handling of materials.
Depending on local markets, materials may need to be packaged or prepared in specific
ways in order to receive the highest value. Vandalism and scavenging of an unsecured
residence may greatly limit the quantity of materials available for salvage or resale.
iii. Liability and Risk Reduction Impacts
Some markets and reuse stores are unable to accept items or materials that contain lead-
based paint. It becomes essential to identify these possible items during the pre-
demolition survey in order to plan accordingly. Local government may also require
special deconstruction permits.
16
-------
iv. Cost Impacts
Deconstruction methods, practices, and markets continue to grow and improve. Full
building deconstruction will require more time and labor than standard demolition, but if
the local market has adequate resale and reuse markets, and if experienced and qualified
deconstruction firms are available, excess costs can be minimized. Oftentimes, a blend
of deconstruction and standard demolition can be accomplished to determine the cost
implications of deconstruction.
A hybrid approach to demolition/deconstruction may include
"light deconstruction" after hazardous materials have been
addressed, by a local non-profit before demolition takes place.
In many cases, the residential homes are stripped of metals
and items of value, which means that full-scale deconstruction
will have limited resale value. The Cincinnati Metropolitan
Sewer District plans to employ this hybrid approach (light
deconstruction/demolition) as preparation for a large-scale
green stormwater infrastructure project in the Lick Run
watershed. Entities using this approach should consider
including language in their bid specifications that would
ensure that all applicable environmental, health, and safety
regulations are followed during light deconstruction.

F. Use Better Backfill and Remove Basements
See Appendix:
Soils for Earthwork
Placement of Fill
Impervious Surface Removal
The 'Soils for Earthwork' bid specification development tool outlines
the use of three distinct materials for backfill. The first is a sandy subsoil to fill the voids created
from basements or other excavations. The second is a thin layer of compost used to amend the site
soils in preparation for vegetation. The final layer is a sandy loam to be used as topsoil. It is
recommended that all materials be sourced from
approved suppliers and be free of contaminants.
The 'Placement of Fill' bid specification
development tool offers suggestions for
adequate compaction of the subsoil to prevent
settling, recommendations for layer thicknesses
for the compost and topsoil, and best
management practices for placement methods
and procedures. Finally, the 'Impervious Surface
Removal' bid specification development tool
lists recommendations for the excavation and
removal of basement foundations, slabs,
driveways, and other impervious surfaces
prior to beginning backfill.
Sewer districts

methods of

services to improve
stormwater
management. As
part of a new trend,
sewer districts are
partnering with municipal public works departments to
convert vacant lots from acres of impervious surface into
decentralized stormwater infiltration systems.
i. Environmental Impacts
The use of sandy soils for backfill is expected to
increase the volume of stormwater that is able to
infiltrate on-site, especially with the removal of
the basement. This in turn reduces the chance of
erosion and sedimentation, and can lower the
volume of runoff entering storm sewers. Applying
compost and topsoil will also aid in the
establishment of vegetation, which further slows
stormwater runoff, prevents erosion and
sedimentation, and lowers runoff volumes.
Cities, counties, land banks or other entities
may stabilize property values by using
proper fill and leaving vacant lots in a more

condition.

Cities and sewer districts may partner together
in order to utilize the residential demolition bid
specifications to facilitate stormwater management
practices. Using sandy soils as backfill is one
strategy to increase stormwater infiltration while
creating certainty of the quality of the fill material
in the event of subsequent reuse.
18
-------
ii. Operational Impacts
The modification of backfill materials is likely to have minimal operational impacts
to residential demolition. Potential impacts may include initial time spent to identify
qualified material suppliers and longer delivery routes. Availability may also be limited
depending on the resources available and the number of sites being demolished. For
basement removal, all the necessary equipment should be on-site, but additional trucks
to haul the concrete may be required, plus additional time to conduct the excavation.
iii. Liability and Risk Reduction Impacts
By pre-screening sources of backfill and potential material suppliers, the project owner
can require that all necessary material testing and analyses are conducted to ensure
that the materials are clean and free of contaminants. This becomes increasingly
important as the number of demolitions increases. By minimizing the potential for
unclean material being placed on site and by
using contaminant free material, the project
owner minimizes future site liabilities.
Contaminant free fill material has obvious
environmental and public health benefits.
iv. Cost Impacts
Depending on market availability and
demand, increases in material costs for
backfill may be minimal. The routine
removal of basements and foundations
not only reduces the future cost to
developers but creates a level of certainty

legacy issues when digging into the subsurface in the course of site reuse. Also,
incomplete impervious surface site work can increase costs for other governmental
units, such as a sewer district that will be forced to address sediment and stormwater
runoff from the site.

G. Install Green Infrastructure and Use Native
or Adapted Seed Mixes and Plants
See Appendix:
Grading Soil Stabilization
and Seeding
The 'Grading' bid specification
development tool is designed to provide best
management practices for general grading of sites in a manner to prevent
ponding of stormwater. Also included in the section is information on the
installation of rain gardens and bioswales. These options are best applied to
specific sites that can accommodate these types of green infrastructure. For
example, a bioswale would be most appropriate if there are multiple
adjacent vacant sites. The 'Soil Stabilization and Seeding' bid specification
development tool makes recommendations for the use of native or adapted
seeds mixes and plants when establishing greenspace on a vacant parcel.
Environmental Impacts
The installation of vegetation at a site has multiple environmental
benefits. First, plants help prevent erosion and sediment transport of
topsoil by binding the

ii. Operational Impacts
Most contractors should have the means
to apply seed and install erosion control
straw. The selection of an appropriate
seed mixture may require some advance
effort to determine the best mix for the
region and climate. The installation of
green infrastructure, however, will likely
require a significant amount of advance
planning and may require the use of a
specialized contractor with unique
experience in the installation of these
features. Furthermore, the project
It is always a good practice to prepare sites for vegetation, but is
absolutely critical when the end use will be a landscaped site. In
some cases, cities like Cleveland and Buffalo are planning ahead
by identifying potential end uses, which may include housing,
community gardens, or green stormwater infrastructure. If the
end use will be a vegetated site then the demolition process can
better prepare the site and reduce future costs for site finishing.
Planning ahead can reduce the need to perform rework.
20
-------
owners will likely need to identify the specific sites that are suitable for green
infrastructure well in advance of soliciting bids and conducting the work.
iii. Liability and Risk Reduction Impacts
Stormwater benefits may accrue over time that can balance out the initial construction
cost. Depending on the systems established in the communities, adjacent parcels, even
if all vacant or slated for demolition, may be owned by different entities. The need
for access agreements and multiple stakeholders will require extra administrative work,
but given the multiple co-benefits of green infrastructure and vacant lot repurposing,
the benefits likely outweigh the costs of pursuing multi-lot projects.
iv. Cost Impacts
There will certainly be an additional cost for requiring seeding after demolition and
backfill if it is not currently a standard practice. On the other hand, the incorporation
of appropriate seed mixtures should present a minimal cost variation. However, if the
selection of seeds and plants is carefully planned, the required maintenance can be
minimized.
Installation of green infrastructure will present additional costs to the overall project.
However, there are stormwater benefits that may accrue over time that can balance out
the initial construction cost. If green infrastructure is incorporated into several
different parcels, those additional costs could be spread to multiple sites, thereby
reducing the per-site increase while still reaping the environmental benefits of the
installation. There may be opportunities to include a cost share of the incremental costs
associated with green infrastructure projects. For example, this cost share may be
between a local stormwater management agency and a municipality or land bank.

In July 2012, U.S. EPA worked with
the Cuyahoga County Land Reutilization
Corporation (CCLRC, also known as the
Cuyahoga Land Bank) to field test four bid specification
development tools related to earthwork:
• Soils for Earthwork.
• Placement of Fill.
• Grading.
• Soil Stabilization and Seeding.
U.S. EPA provided technical assistance to CCLRC to incorporate recommended language and other
changes into CCLRC s earthworks bid specification language. This was an iterative process between
CCLRC and U.S.EPA. Experienced demolition contractors were then selected by CCLRC to conduct
demolitions at five vacant homes using the amended bid specifications. The primary changes to
the demolition process included using a specified sandy soil for backfill, applying compost and/or
topsoil, and working with the Cleveland Botanical Garden to develop a native seed mixture. The field
trial yielded many lessons learned for both CCLRC and
U.S. EPA, including the following:
• The enhanced residential demolition bid
specification development tools may not be
understood adequately without additional guidance.
Users of this report will have to review their own
bid specifications to identify opportunities to
incorporate the ideas and concepts offered in this
report and its Appendix.
• Not all components of the menu of demolition
specifications will be practical or applicable for a
given region, market, or regulatory environment.
• Contractor education of the specification changes
is necessary to ensure compliance with contract
language. Contractor education needs to emphasize
both specification content and intent.
U.S. EPA Region 5 staff
(Chicago and Cleveland) and
a field research team from the
U.S. EPA Office of Research
and Development (Cincinnati)
observed five residential
demolitions in Cleveland's Slavic Village neighborhood.
This demolition was completed by the Cuyahoga County
Land Revitalization Corporation (CCLRC). The land
bank acquired the buildings involuntarily through the
tax foreclosure process in Cuyahoga County. Since
the bid specification language needs to be tailored to
local conditions, U.S. EPA worked with CCLRC on the
implementation of residential demolition bid specifications
that included alternative soil and fill techniques.
22
-------
• Field oversight of contractors is an essential component of producing the desired results listed in
the contract specifications.
• With enough advance notification, contractors have the ability to be flexible and accommodate
changes.
• Backfill materials of a higher environmental quality
are not necessarily more expensive.
• A single hose is not always sufficient for dust control
on larger buildings, and fire hydrants are not always
conveniently located.
• Project information should be available on-site is
helpful when assisting concerned neighboring
residents. This may include results of the pre-
demolition survey, completion dates of asbestos
abatement, abatement and demolition contractor
information, market analyses behind the decision
to demolish a structure, and contact information for
the project owner.
As an outcome of the field testing, the
CCLRC staff was able to illustrate the
need for additional field oversight. Two
additional staff members joined the
CCLRC team to focus on contractor
performance in the field.
In addition to the aforementioned lessons learned, U.S. EPA Office of Research and Development
(ORD) was on-site during the field trial to conduct soils research as part of the Urban Soils
Assessment project. Data was collected from the basement excavations following removal of
all impervious surfaces. Testing included water infiltration, ground-penetrating radar, soils
classification, and compaction testing of existing soils. ORD will return to the sites in 2013 to
reassess soil characteristic and to determine the effectiveness of the field trial.

As discussed in Section 4, one
of the lessons learned from the field
trial with CCLRC was the need to take
into account local conditions when presenting
the residential demolition bid specification tools for use.
Local procurement laws and practices, weather conditions,
climate and even local vegetation needs can impact how a
specification can be adapted for local use. This report identifies
the activities associated with demolishing residences, from pre-planning to
demolition to site rehabilitation. For each of the activities, the report provides
bid specification development tools to assist bid solicitors in developing better bid specifications to ensure
a more environmentally responsible demolition and site rehabilitation. One approach for incorporating
the improved demolition specifications into existing demolition procedures is to first assess the current
state of the demolition bid program. This could include market analyses to determine what aspects of
the specifications would have the greatest economic and environmental impact on the project. If a
new residential demolition program is being created, local land banks, counties, cities, or other entities
are encouraged to apply the appropriate demolition bid specification tools to all bids and contracts that
are utilized in the new program. Ultimately,

the residential demolition specifications
should raise awareness of the multiple
opportunities and methods available to
improve the environmental quality of
residential demolition.
The information in each bid specification
development tools section is intended to be
considered alongside local conditions (e.g.
climate, neighborhood context, or appropriate
vegetation) be considered in order to achieve
the best result. The language in the bid
specification development tools is not
intended to be used as a standalone document,
but rather the concepts and recommendations can be selected and adapted as appropriate for the specific
demolition activity and individual organizations needs. Cost implications, regulatory requirements, and
goals of the organization will all play a significant role in selecting the most effective and implementable
concepts presented in each bid specification development tools section. Individual bid
specification development tools section and instructions for their use can be found ^j Gfe See Appendix
in the Appendix section of this document.
As more cities,
counties, land banks and other entities re-evaluate their
demolition practices, it is possible to modify their contractor
requirements. Applied locally, these environmentally improved
strategies may result in demolition site conditions that are better
for future development.

Health and Safety Disclaimer: Although this document addresses briefly the topic of worker health and safety and public safety and
security at residential demolition sites, it is not the focus of this document. The user should ensure that any residential demolition is
conducted in accordance with all applicable health and safety provisions of Title 29 and Title 40 of the Code of Federal Regulations, as
well as all applicable federal, state and local requirements. One best practice would be to develop a health and safety plan for the project
which establishes personnel protection standards and mandatory safety practices and procedures that protect both workers and the general
public. Additionally, the health and safety plan assigns responsibilities, establishes standard operating procedures, and describes how
unplanned events and incidents will be handled. Additional information on this topic is widely available and the reader should research

Residential Demolition Bid Specification Development Tool
The appendices to this document are known as "bid specification development tools". They
have been designed to serve more than one purpose. They can serve as a tool to help the reader
develop and organize information concerning a demolition project, especially information
about environmental concerns and issues. They can also be can be used to modify existing bid
specification language used by a community or to create language for new bid specifications. This
specification language could then be utilized to develop procurement language, contract language,
and associated documents as appropriate for use in a specific bid package that would instruct
contractors on the contract and on the general and the technical requirements for the demolition
project.
The "bid specification development tools" found in these appendices have been organized by topic
and each follow a similar general format. The general format provides the reader with information
in the following broad categories: Purpose, References, Contractor Required Submittals, Quality
Assurance, Required Materials, and Execution. Each of these categories is designed to provide
information and resources to the reader so that the reader can develop or modify their own written
requirements concerning the individual topics for their demolition project.
Note that the appendices and topics are designed to be a tool to formulate specification language,
but should not be interpreted or utilized as specification or contract language itself. They are not
intended to cover all components of a demolition project nor can they be expected to cover all the
local conditions in your community. They are not intended to reflect all applicable local, state, nor
federal laws and requirements. The reader will have to work within their organization and their local
jurisdiction to make sure that the language they use in their documents is appropriate and addresses
the needs of their community.

On the Road to Reuse: Residential Demolition Bid Specification Development Tool
EPA 560K13002 (September 2013)
General Requirements
PRE-DEMOLITION SURVEY
PURPOSE
This section recommends provisions that cities, counties, land banks and other entities may consider
adapting for specifications soliciting contractors for demolition work. Some of the provisions provided
below are based on regulatory requirements. The regulatory requirements apply irrespective of whether
they are included in a bid specification, and the potential specifications included below do not include
an exhaustive list of regulatory requirements. Requirements may vary depending on the particular
facts of the demolitions at issue and any state or local requirements. The cities, counties, land banks,
other entities and contractor should consult the relevant regulatory requirements, including those
specified in the References section below, in preparing for the demolition.
Also included below are some potential specifications that are not required by regulation, but rather are
suggestions for cities, counties, land banks and other entities to consider including when developing
bid specifications and contracts for residential demolitions.
These recommended provisions are written as they might appear in an organizations bid specification
and thus are framed in mandatory language. Such language is not meant to imply the existence,
creation, or reinterpretation of any regulatory requirement. Such provisions represent best practices
and are tools available to the city, county, land banks or other entity to consider while developing bid
specifications and contracts. The goal of the Pre-Demolition Survey bid specification development
tool is to provide information to the contractor to conduct a complete and thorough inspection and
survey of the salvageable materials, non-hazardous wastes (including recyclable waste materials),
and potential hazardous waste streams within residences prior to beginning demolition. The results
of the pre-demolition survey would be presented in an inspection report and incorporated into
the demolition bid package, which would in turn be used to develop the Waste Management Plan.
Potential wastes stream covered by this section include:
• Asbestos-containing materials (ACM).
• Lead-based paint (LBP).
• Polychlorinated biphenyls (PCBs).
• Mercury.
• Refrigerants.
• Electronic waste.
• Salvageable materials (e.g. bricks, furniture,
flooring, doors).
• Recyclable demolition materials (e.g. wood, concrete, metal, shingles).
• Other household waste.

A. The contractor responsible for conducting the pre-demolition survey agrees to submit the
results of the pre-demolition survey in an inspection report for inclusion in the demolition bid
package. This information will be used by the demolition contractor to develop the Waste
Management Plan, as described in the Waste Management Plan bid specification development
tool. The inspection report should also include visual photographic documentation to identify
materials, existing conditions, and sample locations corresponding with analytical reports.
QUALITY ASSURANCE
A. All surveying must be performed by personnel with experience conducting pre-demolition
surveys in residences. When required by state and/or local regulations, all asbestos inspection
activities must be completed by a licensed asbestos inspector and all lead inspection

PURPOSE
This section recommends provisions that cities, counties, land banks and other entities may consider
adapting for specifications soliciting contractors for demolition work. Some of the provisions provided
below are based on regulatory requirements. The regulatory requirements apply irrespective of whether
they are included in a bid specification, and the potential specifications included below do not include
an exhaustive list of regulatory requirements. We cannot provide such an exhaustive list because
requirements may vary depending on the particular facts of the demolitions at issue and any state or
local requirements. The city, county, land banks and other entities and contractor should consult the
relevant regulatory requirements, including those specified in the References section below, in preparing
for the demolition.
Also included below are some potential specifications that are not required by regulation, but rather are
suggestions for city, county, land banks and other entities to consider including when developing bid
specifications and contracts for residential demolitions.
These recommended provisions are written as they might appear in a city, county, or land bank's bid
specification and thus are framed in mandatory language. Such language is not meant to imply the
existence, creation, or reinterpretation of any regulatory requirement. Such provisions represent best
practices and are tools available to the cities, counties, land banks and other entities to consider while
developing bid specifications and contracts.
By including provisions concerning a Waste Management Plan in a bid specification for residential
demolitions, a city, county, land banks and other entities would provide information to the Contractor to
assist in the development of a Waste Management Plan for use in managing non-hazardous, hazardous,
and special waste streams during demolition.
This section includes potential provisions for bid specifications on:
• Waste stream identification and disposition of wastes and materials, with an emphasis on
material recovery.
• Coordination and sequencing of waste removal.
• Transportation, management, and disposal requirements for waste streams.
• Salvage, recycling, and disposal facility requirements.

Waste Management Plan 101
For residential demolition, it is essential
for the contractor to identify the planned
methods for abating, removing, staging,
transporting, and disposing of various waste
streams. The following list of questions
may help clarify the basis of the Waste
Management Plan:
• What are the identified waste streams?
• How will each waste stream be removed
safely and legally?
• Can materials be salvaged or recycled?
• Where will waste streams be disposed?
• How will the material be transported?
• Who will transport the wastes?
• What special requirements should be
considered in the plan?
F.
The Waste Management Plan shall identify each party responsible for implementation of
specific requirements (e.g. asbestos abatement contractor, site superintendent, salvage
firms) to ensure accountability.
G. Provide in the Waste Management Plan a figure or map
which presents the delineation of all temporary staging
areas for segregated waste streams.
In addition to training related to the
Waste Management Plan, it is typical
for a project to have a separate Health
and Safety Plan that identifies health
and safety training requirements.
H. Provide in the Waste Management Plan a discussion on
containment procedures for removal and decontamination
procedures for both equipment and personnel when handling various waste streams to
prevent cross-contamination. Comply with the prohibition on intentional venting of
refrigerants during the disposal of refrigeration and air conditioning equipment.
I. Coordination: The contractor shall establish lines of communication between the
stakeholders, including the owner or city, county, land bank or other entity, abatement
subcontractors, disposal facilities, site inspectors, and others as necessary. The contractor
will be responsible for disseminating contact information, notifications, notification
revisions, inspection reports, and all other pertinent information to all parties
throughout the duration of the project. Alternatively, the contractor must ensure that
another designated party conducts the duties of this paragraph.
J. Sequence: Upon identification of the anticipated waste streams at the site, the contractor
shall present in the Waste Management Plan the intended sequence of removal operations.
This sequence must identify any subcontractors that will be performing specific tasks, such
as removal of items for salvage, and must identify potential conflicts of materials and tasks
(e.g. ACM that needs to be abated and is located under a salvageable item).
K. Transportation and Disposal: Include in the Waste Management Plan identification
of transporters; proposed salvage centers, recycling centers, and disposal facilities;

as applicable:
1. Packaging or processing requirements for incoming materials.
2. Restrictions and testing requirements.
3. Disposition of rejected loads.
4. End use of materials.
P. Newly Discovered Waste Streams: The Waste Management Plan should include procedures for
handling newly discovered but unidentified or suspicious materials that is encountered during
performance of work at the site. At a minimum, the requirements for sampling and laboratory
analysis must be followed, as discussed in the "Pre-Demolition Survey" bid specification
development. This requirement applies to ACM, LBP, polychlorinated biphenyls (PCBs), ~
mercury-containing wastes, universal wastes, household wastes, non-hazardous wastes, or ^

PURPOSE
This section recommends provisions that cities, counties, land banks and other entities may consider
adapting for specifications soliciting contractors for demolition work. Some of the provisions provided
below are based on regulatory requirements. The regulatory requirements apply irrespective of whether
they are included in a bid specification, and the potential specifications included below do not include an
exhaustive list of regulatory requirements. We cannot provide such an exhaustive list because requirements
may vary depending on the particular facts of the demolitions at issue and any state or local requirements.
The cities, counties, land banks, other entities and contractor should consult the relevant regulatory
requirements, including those specified in the References section below, in preparing for the demolition.
Also included below are some potential specifications that are not required by regulation, but rather are
suggestions for cities, counties, land banks and other entities to consider including when developing bid
specifications and contracts for residential demolitions.
These recommended provisions are written as they might appear in an organization's bid specification
and thus are framed in mandatory language. Such language is not meant to imply the existence, creation,
or reinterpretation of any regulatory requirement. Such provisions represent best practices and are tools
available to the city, county, land banks or other entity to consider while developing bid specifications and
contracts.
The goal of the Waste Handling and Disposal specification tool is to assist the contractor in executing the
Waste Management Plan for all hazardous, special, and non-hazardous waste streams generated during
demolition. This section does not include materials that are to be salvaged or recycled. The section
includes: Execution requirements for the handling and disposal of hazardous, special, and non-hazardous
waste streams

This section recommends provisions that cities, counties, land banks and other entities may consider
adapting for specifications soliciting contractors for demolition work. Some of the provisions provided below
are based on regulatory requirements. The regulatory requirements apply irrespective of whether they are
included in a bid specification, and the potential specifications included below do not include an exhaustive
list of regulatory requirements. We cannot provide such an exhaustive list because requirements may vary
depending on the particular facts of the demolitions at issue and any state or local requirements. The cities,
counties, land banks, other entities and contractor should consult the relevant regulatory requirements,
including those specified in the References section below, in preparing for the demolition.
Also included below are some potential specifications that are not required by regulation, but rather are
suggestions for cities, counties, land banks and other entities to consider including when developing bid
specifications and contracts for residential demolitions.
These recommended provisions are written as they might appear in an organizations bid specification
and thus are framed in mandatory language. Such language is not meant to imply the existence, creation,
or reinterpretation of any regulatory requirement. Such provisions represent best practices and are tools
available to the city, county, land banks or other entity to consider while developing bid specifications and
contracts.
The goal of the Asbestos Compliance bid specification development tool is encourage cities, counties, land
and other entities to help ensure that all residential demolitions follow general best practices and the National
Emissions Standards for Hazardous Air Pollutants (NESHAP) regulations for asbestos whether or not the
asbestos NESHAP is applicable to the demolition. This section includes:
• Provisions for asbestos.
• Coordination among stakeholders.
• Additional management practices for asbestos.
Provisions concerning the handling and disposal of
asbestos-containing waste materials can be found in the
Waste Handling and Disposal and Waste Management Plan

E. 29 CFR 1926.1101 - OSHA Construction Safety and Health Regulations for Asbestos
CONTRACTOR REQUIRED SUBMITTALS
A. The contractor is required to ensure that the demolition notification form for asbestos
abatement is submitted to the appropriate U.S. EPA, state or local agencies, including any
applicable fees, a minimum of 10 working days prior to beginning any asbestos
removal work, which includes any activity that would breakup, dislodge, or disturb
asbestos-containing materials (ACM). All required information on the form must be
completed, and the inspection report from the 'Pre-Demolition Survey' should be reviewed
and consulted in preparing the notification. If information on the notification changes, it shall
be the responsibility of the contractor and owner/operator to ensure that revisions to the
notification are submitted to the appropriate U.S. EPA, state or local agencies in a timely manner.
B. The requirements in the notification form also apply to the owner and the operator of
the demolition operation.
QUALITY ASSURANCE
A. The basis for this specification section is the NESHAP regulation for asbestos,
located at 40 CFR Part 61, Subpart M supplemented by additional practices not required by the
regulation. Specifically, 40 CFR §61.145(a) requires a thorough inspection, as discussed in the
'Pre-Demolition Survey' bid specification development. The asbestos NESHAP also covers the
requirements for notification and asbestos emission controls also known as work practices to
be used when removing regulated ACM (RACM). In 40 CFR §61.150, waste handling,
transportation, and disposal requirements are outlined, including a prohibition on visible
emissions and shipping and disposal documentation.
B. The contractor shall be familiar with the NESHAP regulation as it applies to reporting,
recordkeeping, and ACM handling requirements for demolitions. This includes
requirements for buildings that are determined by a State or local government Agency to
be structurally unsound and in danger of imminent collapse. The requirements of the
asbestos NESHAP are applicable throughout the entire project, including all demolition
that follows asbestos abatement because previously undiscovered ACM could be
discovered within a structure or at a site as demolition proceeds. 3
C. Local ordinances or state laws may establish additional requirements related to asbestos 2"
and contractors shall check with local and state authorities to ensure they are aware of Q
applicable requirements before beginning any demolition, deconstruction, or renovation 8
activity. _g
D. As a best practice, all work conducted at the site related to asbestos must be performed ^
by personnel with sufficient experience in conducting similar asbestos work in =
residences. When required by federal or state regulations, all asbestos-related activities i
must be completed by accredited contractors and personnel. In addition, state _•/>
regulations may require the contractors and personnel to obtain a state license for •=
asbestos abatement activities. j

NOTIFICATION
A. In addition to the notification requirements of 40 CFR Part 61 Subpart M, the contractor
shall:
1. Provide the city, county, land bank or other entity that owns or controls the property
copies of the licenses and accreditations for all personnel involved in the abatement
work.
2. Confirm in writing to the demolition contractor the procedures to be followed in the
event that unexpected RACM is discovered or if Category II nonfriable ACM becomes
friable.
COORDINATION
A. A communication plan shall be established among all
stakeholders of the project, including at a minimum, the owner
(city, county, land bank or other entity), building inspectors,
asbestos abatement firm, demolition contractor, salvage or
recycling firm, universal waste technicians, waste haulers, and
oversight personnel.
The city, county, land bank or
other entity that is conducting
the project should determine
prior to soliciting bids which
party, or parties, will be
responsible for development of
the communication plan and, if
necessary, include it as a required
submittal of the winning bidder.
B. The contractor shall coordinate
distribution of contact information such that all
stakeholders will receive copies of the notification
forms, demolition permits, or revisions to notification
forms. All stakeholders work to ensure that the
requirements established within the NESHAP
regulation, the site-specific demolition permit, and
the methods described on notification forms are
adhered to according to plan.
It is common industry practice for
independent, third-party oversight
contractors or consultants to monitor
the work conducted by the asbestos
abatement contractors. As a best practice,
oversight personnel should be provided
with all project information in a timely
manner.
REMOVAL
n:
N
n:
A. The removal of all RACM in accordance with 40 CFR Part 61, Subpart M, and Appendix A
to Subpart M, must be completed prior to commencing any demolition activities, except
at facilities being demolished under an order of a State or local government agency,
issued because the facility is structurally unsound and in danger of imminent collapse.
B. If a facility has been determined by a state or local government agency to be structurally
unsound and in danger of imminent collapse, RACM may be left in place during
demolition provided that all applicable requirements in 40 CFR Part 61, Subpart M are
followed for such situations.
C. The contractor may schedule the salvage firm or others to work prior to or in
coordination with the abatement firm, provided that all NESHAP requirements and
OSHA health and safety requirements are met.
D. Newly Discovered ACM: Should any newly discovered potentially asbestos-containing
materials be encountered at the site, the requirements for sampling and laboratory
analysis must be followed, as discussed in the 'Pre-Demolition Survey' section. The
presence of newly discovered ACM may require a revision to notifications submitted
previously or may require a new notice.

-------
BEST MANAGEMENT PRACTICES
A. The abatement firm should collect and filter all wastewater generated during the
abatement process, including decontamination of personnel. Prior to discharge to public
sewers the water must be filtered using a high-efficiency particulate air (HEPA) filter.
Alternatively, the contractor should consult with the local Publicly Owned Treatment
Works (POTW) to determine the acceptable discharge limit for asbestos.
B. The contractor should provide at least one inspection viewing port that allows a clear
view of as much of the asbestos removal work area as is feasible without requiring entry
to a contaminated zone. The viewing port should be located between 4 and 6 feet above
the floor level. When possible, multiple inspection ports may be installed to further
improve oversight of removal operations.
C. Samples collected by personal air monitors shall be analyzed with a one-day turnaround
time or faster and results of all air samples shall be immediately distributed to the project
stakeholders, including at a minimum oversight personnel and the city, county, land
bank or other entity that owns or controls the property. Results of the samples shall be
used to determine if improper removal techniques are being used frequently or
consistently and whether work practices need to be amended to mitigate risk and
exposure to site workers.
D. To assist inspectors in confirming adequate wetting of waste materials, clear plastic shall
be used on all layers of bagging for wrap-and-cut removals of RACM, in addition to the
standard labeling requirements. Opaque or black
plastic sheeting should be avoided.
E. All asbestos waste containers shall be closed and
locked at the end of each work shift. Waste
containers that have reached capacity shall be
hauled from the site for proper disposal the
following work day at the latest.
Asbestos waste bags that contain
metals or other items with value
are at risk of being opened, with
a resulting hazard of airborne
asbestos. This risk can be
minimized through effective
security measures.

PURPOSE
This section recommends provisions that cities, counties, land banks and other entities may consider
adapting for specifications soliciting contractors for demolition work. Some of the provisions provided
below are based on regulatory requirements. The regulatory requirements apply irrespective of whether
they are included in a bid specification, and the potential specifications included below do not include
an exhaustive list of regulatory requirements. We cannot provide such an exhaustive list because
requirements may vary depending on the particular facts of the demolitions at issue and any state or
local requirements. The cities, counties, land banks, other entities and contractor should consult the
relevant regulatory requirements, including those specified in the References section below, in preparing
for the demolition.
Also included below are some potential specifications that are not required by regulation, but rather are
suggestions for cities, counties, land banks and other entities to consider including when developing bid
specifications and contracts for residential demolitions.
These recommended provisions are written as they might appear in an organization's bid specification
and thus are framed in mandatory language. Such language is not meant to imply the existence, creation,
or reinterpretation of any regulatory requirement. Such provisions represent best practices and are tools
available to the city, county, land banks or other entity to consider while developing bid specifications
and contracts. The goal of the Managing Fugitive Dust bid specification development tool is to provide
requirements for the contractor to prevent workers and members of the public from being exposed to
fugitive dusts that may be generated during demolition activities. Specific hazards in this section include:
• Lead-based paint (LBP).
• Polychlorinated biphenyls (PCBs).
• Other sources of hazardous dusts.

would burn seeds or planting stock, or otherwise impede or prevent plant growth.
For example, compost shall be tested for maturity and stability with a gaseous test that
measures carbon-dioxide (CO2) and ammonia (NH3), which are the two most
common gaseous emissions of composting materials. High rates of emission of either
or both gases are indicative of an unstable, unfinished compost that is still actively
degrading.
11. Soluble salt concentration may vary but must be reported, with a preferred salt content
of 2.5 decisiemens per meter (dS/m) or millimhos per centimeter (mmhos/cm)
for the soil/compost blend. The soluble salt concentration of the amended soil should
not exceed approximately 1.25 dS/m where seeds, young seedlings, or salt-sensitive
crops are to be planted.

(including any construction rubble, or other man-
made items).
6. Screening: Single screened.
7. Acidity range (pH) of 5.5 to 7.5.
8. Containing minimum of 4 percent and maximum of 25
percent organic matter.
Sandy Loam: Soil having this
texture consists of soil materials
containing somewhat less sand,
and more silt plus clay, than loamy
sands. As such, they possess
characteristics which fall between
the finer-textured sandy clay loam
and the coarser-textured loamy
sands. Many of the individual
sand grains can still be seen and
felt, but there is sufficient silt and/
or clay to give coherence to the
soil so that casts can be formed
that will bear careful handling
without breaking.

On the Road to Reuse: Residential Demolition Bid Specification Development Tool
EPA 560K13002 (September 2013)
Earthwork
GRADING
PURPOSE
This section recommends provisions that cities, counties, land banks and other entities may
consider adapting for specifications soliciting contractors for demolition work. Some of the
provisions provided below are based on regulatory requirements. The regulatory requirements
apply irrespective of whether they are included in a bid specification, and the potential
specifications included below do not include an exhaustive list of regulatory requirements.
We cannot provide such an exhaustive list because requirements may vary depending on the
particular facts of the demolitions at issue and any state or local requirements. The cities,
counties, land banks, other entities and contractor should consult the relevant regulatory
requirements, including those specified in the References section below, in preparing for the
demolition.
Also included below are some potential specifications that are not required by regulation, but
rather are suggestions for cities, counties, land banks and other entities to consider including
when developing bid specifications and contracts for residential
demolitions.
These recommended provisions are written as they might
appear in an organization's bid specification and thus are framed
in mandatory language. Such language is not meant to imply
the existence, creation, or reinterpretation of any regulatory
requirement. Such provisions represent best practices and are
tools available to the city, county, land banks or other entity to
consider while developing bid specifications and contracts.
The goal of the Grading bid specification development tool is to
provide information to the contractor for finish grading on lots,
and especially to establish grading practices appropriate for the
installation of green infrastructure features in the final landscape
plan for properties following residential demolition. The section
includes
• General Grading Guidelines.
• Special grading requirements for stormwater.

Please refer to the "Purpose" portion of this section for an explanation of why the language appears as it does and how it might be useful.
Property Owners:
The application and use of this section
will need to be determined on a site-
by-site basis. Topography, location of
adjacent structures, size of parcels, and
existing landscaping to remain will all
impact whether a site is suitable for green
infrastructure features since there are
special grading requirements for runoff
management practices like rain gardens or
bioswales. During the planning phases of
residential demolition and prior to bidding,
the city, county, land bank or other entity
that owns or controls the property should
define whether a combination of some,
all, or none of these grading needs will
be included in the scope of work. Other
regional entities may also be consulted for
contribution of resources to help install
green infrastructure features.

E. Scarify in areas where equipment used for hauling
and spreading topsoil has compacted subsoil.
Only low ground-contact pressure equipment or
hand tools may be used for topsoil placement, as
included in the 'Placement of Fill' bid specification
development tool.
SEEDING
A. Rake soil surface smooth prior to seeding. Follow
immediately with erosion control over entire
seeding area ensuring complete coverage.
B. Native seed mix shall be applied across the entire
property.
C. Broadcast seed at rate in accordance with supplier's
recommendation evenly in two intersecting
directions.
D. Rake or use roller to establish seed soil contact at
approximately Va-inch depth
E. Do not seed areas in excess of what can be stabilized
with erosion control matting on the same day.
F. Planting Season: In accordance with seed supplier's
recommendation.
Alternate Seeding Method: Hydroseeding
• Seed and mulch shall be applied
simultaneously in a water slurry via hydraulic
seeder/mulcher.
• Hydraulic seeder/mulcher shall be capable of
applying the homogeneous materials
uniformly and the discharge pumps and gun
nozzles shall be kept free of buildup.
• Hydraulic seeding/mulching equipment shall
have the tank volume certified by a plate
affixed by manufacturer.
• Application of Materials: Measure the
quantity of each material to be charged into
the hydraulic seeder/mulcher tank following
manufacturer directions. For advanced users,
the applicator system can be calibrated either
by mass or by a system of mass calibrated
volume measurements. Add the materials
to the tank while it is being loaded with
water. Thoroughly mix the materials into
a homogeneous water slurry and distribute
uniformly over the designated surface area.
Apply seed and mulch within 2 hours of being
charged into the hydraulic seeder/mulcher
tank. During loading of the hydraulic seeder/
mulcher tank, add materials in the following
sequence: water, then seed, then mulch.
• Blend into existing adjacent grass areas to
bond new growth to existing adjacent areas
or to previous applications to form uniform
surfaces.
• Seeding and mulch shall overlap adjoining
vegetation by 12 inches but shall not pass
the property boundary without the written
permission of the adjacent property owner.
• Mulching material shall be free of weeds
and other foreign materials; free of growth- or
germination-inhibiting ingredients;
manufactured in such a manner that after
addition and agitation in slurry tanks with
water, the fibers in the material will become
uniformly suspended to form a homogeneous
slurry; dyed a suitable color to facilitate
inspection of the placement of the material;
when applied, capable of forming an
absorptive mat, which will allow moisture to
percolate into the underlying soil.
G. Do not apply materials over snow, ice, frozen ground, or standing water.
H. Do not apply seed when wind conditions are such that material would be carried beyond
designated area or that materials would not be uniformly applied or when wind velocity exceeds 10
miles per hour. No seeding shall be performed when even distribution cannot be attained.

SEED AND PLANT PROTECTION
A. Protect seeded and planted areas from damage by identifying areas with stakes and string
around the area periphery.
B. Cover all seeded areas with a straw blanket for erosion control.
C. Install matting on dry ground and in accordance with manufacturer's recommendation.
D. Roll matting without stretching or pulling.
E. Lay smoothly on ground surface and bury the ends of each section in a 6-inch deep
excavated topsoil trench. Overlap edges and ends of adjacent rolls a minimum of 12 inches.
Backfill trench and rake until smooth and level with adjacent soil.
F. Secure outside edges and overlaps at 36-inch intervals with stakes.
G. Lightly dress slopes with topsoil to ensure close contact between fabric and soil.
H. Install matting in accordance with manufacturer's instructions.
I. Suspend installation operations whenever climatic conditions, as determined by engineer or
manufacturer's representative, are unsatisfactory for placing matting to the requirements of
this section.
PLANTING
A. Add sufficient water to prevent plugs and soil from drying out.
B. Planting holes or slits shall be deep enough to allow the crown of the plant to be at grade
level, while roots extend vertically into the substrate without kinking.
C. Use sufficient water to prevent plugs and surrounding soil from drying out.
D. Plants are to be planted in random clusters of 10 to 20 per species.
MAINTENANCE
A. Commence maintenance immediately after area is seeded and planted. Maintain seeded
areas for year(s) from the date seeding and planting is completed or until native
grass is well established and exhibits vigorous growing conditions, whichever is longer. The
vegetative cover must also be free of eroded, bare, or dead spots and be at least 98 percent
free of weeds. The contractor shall be responsible for repair or replacement of damaged
01 vegetation.
"S B. Prohibit all traffic over finished surfaces.

T3 C. Water deeply and often enough to prevent plants and soil from drying out. Using a low-
^ volume output sprinkler over a period of a few hours will help move water more deeply into
— the soil where it will be retained for later use.
