Overview of Alternatives

 

Here we can follow Anderson's advice closely.  This section aims to provide your readers with a solid understanding of what the alternatives are to solve the problem.  In other words, you're presenting possible solutions.  Anderson states:  "Often you can foster this understanding with a short explanation, perhaps only a sentence long" (p.549).  However sometimes you may need to explain alternatives in detail and cite several of your secondary sources, particularly to describe the more technical facets involved in your alternatives.  

 

For Example:

 

Development of Alternatives In order to meet the RAOs, 59 alternative scenarios were developed for remediation of the PCB-contaminated sediments in the three sections of the Upper Hudson River. The alternatives were developed by combining potentially applicable sediment remediation technologies from among those that remained after the technology screening (treatment and disposal options were considered separately, as discussed below). The initial list of alternatives that were evaluated can be grouped into the following alternative categories:

 

Alternative 1: No Action. This alternative is equivalent to baseline conditions. It includes no source control at GE Hudson Falls, no institutional controls, and no action with respect to the PCBs in the sediments in the Upper Hudson River. Five year reviews would be required.

 

Alternative 2: Monitored Natural Attenuation (MNA) (with Source Control at GE Hudson Falls) and Institutional Controls. This alternative includes implementation of source control measures at GE Hudson Falls pursuant to a separate NTCRA and monitoring, but no active remediation, of the PCBs in the sediments. Five year reviews would be required.

 

Alternative 3: Containment (capping) of Target Areas, MNA (with Source Control at GE Hudson Falls) and Institutional Controls. Alternative Category 3 includes placement of an engineered cap on target areas and protection of the cap from damage by boat propellers and anchors, bioturbation and other disturbances with backfill suitable for benthic and fish habitat. Five year reviews would be required.

 

Alternative 4: Removal (dredging) of Target Areas and MNA (with Source Control at GE Hudson Falls) and Institutional Controls Alternative Category includes removal of PCBcontaminated sediment, isolation of residual PCBs in sediments that may remain after dredging through placement of backfill suitable for benthic and fish habitat in target areas from which the sediments are removed, and several post-removal option categories for handling the removed sediments. Five year reviews would be required.
