Nine Minimum Controls (NMC)
NMC No. 6 - Control of Solid and Floatable Materials in CSO's
The
sixth NMC is intended to reduce or, preferably, to eliminate visible floatables
and solids through modifications and additions to the CSO facilities.
Modifications may include, but not be limited to the use of baffles, screens,
and racks to remove coarse solids, and skimmers and booms to help remove
floatables. Documentation for this NMC may include, but not be limited to,
the following:
-
An
engineering evaluation of procedures or technologies considered for
controlling solid and floatable materials.
-
A
description of CSO controls in place for solid and floatable materials.
-
A
cost estimate and implementation schedule for each of the control
measures being implemented.
-
An
estimate of the decrease in solids and floatables expected from the minimum
control efforts.
-
Documentation
of any additional controls to be installed or implemented.
