On October 21, 1999, the CPUC approved the Williams original application
for ten routes and issued a Certificate of Public Convenience and Necessity.
In February 2000, Williams filed a Petition to Modify their application.
This petition added a new route from Riverside to San Diego.
Pursuant to CEQA where subsequent changes are proposed in a project which
will require important revisions of a previous Negative Declaration, the
CPUC has prepared a Subsequent Initial Study/Draft Mitigated Negative
Declaration (IS/DMND) on the new route. An IS/DMND describes a
project and its potential impacts on the environment, and preliminarily
concludes that any significant impacts that may result from the project can
be either eliminated, or reduced to a level that is not significant, by the
adoption and implementation of specified mitigation measures.
