CMP319: Consequential changes to Section 11 of the CUSC as a result of CMP280 and/or CMP281

As part of the Workgroup analysis, the Workgroup identified that CMP 280 and 281 are charging modification and as such can only change section 14 of the CUSC.  If either modification is approved changes to other none charging sections of the CUSC will be required. These changes cannot be achieved with CMP280 And CMP281.  The principle addition related to the definitions of storage as a class.  The definitions are common to CMP 280, 281 and their alternates.
