 Framework for Dredged Material Management
May 2004
Duration and significance of adverse effects should a given control prove to
be ineffective.
Availability, feasibility, timeliness, and cost of additional management actions
should they be required.
3.5.6 Retention of Environmentally Acceptable Alternatives
With the completion of detailed testing and assessments and the consideration of
management and control measures for the respective alternatives, a determination of
environmental acceptability is made. This determination must ensure that all applicable
standards or criteria are met. If control measures were considered, a determination of the
effectiveness of the control measure in meeting the standards or criteria must be made. If
all standards or criteria are met, the alternative can be considered environmentally
acceptable. At this point in the framework, socioeconomic, technical, and other
applicable environmental considerations must be evaluated prior to the selection of a
management alternative.
3.6 Alternative Selection
The detailed assessment of alternatives may result in one or more alternatives
which are environmentally acceptable. Weighing and balancing of all environmental,
technical, and economic factors must be conducted before the selection of the
preferred/proposed alternative by the lead agency. The process for conducting this
weighing and balancing is described in the implementing regulations of
NEPA/CWA/MPRSA.
The major steps for coordination and documentation associated with alternative
selection are illustrated in Flowchart 3-1. The coordination and documentation process
includes draft and final NEPA/CWA/MPRSA documents, Public Notices, and a final-
decision document which addresses comments on the draft NEPA/CWA/MPRSA
documents.
The selection of a preferred/proposed alternative is based on environmental
acceptability, technical feasibility, costs, and other factors, as appropriate. A detailed
discussion of factors in decision making other than environmental acceptability is beyond
the scope of this document. However, considerations in alternative selection, including a
description of the procedures to be followed with respect to NEPA, CWA, and MPRSA,
are discussed in Chapter 7. Once an alternative has been selected, proper coordination
and documentation has been completed, and a final-decision document has been issued,
the project should be in compliance with NEPA and all applicable environmental laws
and regulations.
