Impact/Compensation Assessment Method (ICAT)

Application for Utility Corridors

What is ICAT

Modification of the Charleston Method. • Factor definitions revised to reflect South Louisiana

conditions and reflect the watershed approach to compensation brought about by RGL 02-2.

• Some Charleston factors removed and others split. • Overall weightings remain the same. • Weighting of factors changed depending upon

perceived importance by the ICAT work group.• Calculations unaltered (except for cumulative effect)

Why Are We Developing A New Assessment Method

Other methods produce inconsistent and unpredictable results among users

Data collection requiring some degree of expertise

Benefits Expected From ICAT

Has repeatable results among interdisciplinary project managers having variable regulatory experience

Provides a quick and easy assessment methodology

Requires minimal amount of field data collection Uses a single set of worksheets applicable to all

habitats.

An Example Pipeline ProjectApplication # MVN-2006-qxyz

Project Specifics

Impacting high quality, relatively undisturbed forested ecosystem.

30 acres in permanently cleared right-of-way. 15 acres in temporary work areas to be

restored upon completion of the work. Compensation to be provided offsite, within

the basin of impact at either a bank or site specific.

Summary Table

Site Specific Mitigation Project

100-acre site currently in sugar cane. The agricultural area no longer exhibits wetland vegetation and hydric conditions but soils are hydric by definition on all but 5 acres.

Propose to effectively restore hydric conditions to hydric soils and plant the site with hardwood species common to the area.

Perpetual conservation easement to be held by a recognized private land trust.
