|This guide presents general considerations for application of
engineering controls to facilitate continued use or redevelopment
of properties containing chemical-affected soil, groundwater, or
other environmental media, due either to chemical releases or
naturally-occurring conditions. This guide is not meant to be
prescriptive but rather to present considerations for evaluating
technologies capable of addressing potential human exposures
associated with chemical-affected environmental media.
Table 1 lists the considerations that should be taken into
account when developing an engineering control in accordance with
This guide is intended for use by real estate developers,
civil/structural designers, environmental regulators, industrial
parties, environmental consultants, and other persons concerned
with residential, commercial, or industrial development of real
properties where chemical-affected environmental media are present.
The design process should involve the individuals and firms working
on various aspects of the specifications for construction,
operation, and maintenance. If the site is located on public
property, then public participation should be considered during the
This guide is directed toward properties where chemical-affected
environmental media, associated with either human-influenced
activities or naturally-occurring conditions, will remain in place
and where active or passive engineering controls will be used to
reduce or eliminate exposures that may otherwise pose an
unacceptable risk to property users.
This guide identifies the exposure concerns associated with
chemical-affected properties that may affect the property
development plan, both in the construction phase and during the
proposed use of the property; defines performance standards for
control of applicable exposure pathways; and, for each exposure
pathway, provides examples of engineering controls that may be
applied for new or existing construction.
This guide will assist in identification of the optimal property
development plan for a property with chemicalaffected environmental
media. Such a plan will address both short-term construction issues
and long-term exposures of property users.
This guide does not address the broader range of environmental
concerns that are not directly affected by construction measures
and engineering controls (e.g., protection of water resources or
Detailed specifications for site-specific application of
engineering controls are not addressed in this guide. The user is
referred to other related ASTM standards and technical guidelines
regarding the implementation of the site evaluation and corrective
action process, as well as the detailed design, installation,
operation, and maintenance of these engineering controls.
The overall strategy for addressing unacceptable risks may
employ either remedial actions or activity and use limitations, or
both. Engineering controls are a subset of remedial actions given
that (1) remedial actions involve cutting off the exposure
pathway or reducing the concentration of COCs, or both and
(2) that engineering controls only involve cutting off the
exposure pathway. Engineering controls are briefly described in
Guide E2091, which describes a broad range of options for managing
risk. This guide covers implementation of engineering controls in a
detailed manner, thereby providing a needed complement to the
information provided in Guide E2091.
The values stated in SI units are to be regarded as standard. No
other units of measurement are included in this standard.
This standard does not purport to address all of the safety
concerns, if any, associated with its use. It is the responsibility
of the user of this standard to establish appropriate safety and
health practices and to determine the applicability of regulatory
limitations prior to use.
