Section 375.205 Special
Analysis for Congested Areas
In small drainage basins
receiving combined sewer overflows from collection systems belonging to several
separate governing bodies the significance of the aggregate CSO load may well
dictate a basin wide evaluation of alternate control levels in lieu of community
by community evaluation. Resolution of CSO issues in such basins may require
evaluation of all CSO sources concurrently with cooperative data collection
efforts involving several communities. This is especially applicable in major
metropolitan areas.
