Re: RE VI SE D, CMR-003 (reque st for time ex ten sion/sequenc e changes) fo r No rt h and So uth H olly WTP
Conversi o n From Gaseous Chlo rine a nd Am monia
Dear Mr. Chris Harder,
The purpose of this writing is to make a formal request for time extensions / changes with interim and
completion milestones on the above referenced project. We are requesting the followin g :
• Waive the January 16 , 2012 interim milestone (North Holly commissioning of sodium hypochlorite).
• Extend the interim milestones (North and South Holly commissioning of liquid ammonium sulfate &
sodium hypochlorite, with one ammonia storage tank in serv ice ) from April 15 , 2012 to April 30 , 2012.
• Extend interim milestone requirement (installation and commissioning of the 2"d ammonia tank ) from
April 15 , 2012 to substantial completion date of May 27 , 2012 .
• No change to the completion milestones (substantial completion) May 27 , 2012 and (final completion)
Jul y 31 , 2012.
Our justification for the requested time extensions / sequence changes can be attributed to the loss of 30 + days
due to abo ve normal precipitation, particularly the January 25 , 2012 and February 18 , 2012 rain events that
flooded critical work areas , made access nearly imposs ible to many of these areas and required extensive
cleanup. We also have or will perform extra critical path work associated with increased quantities with crack
injection and sealing of top concrete decks at new hypochlorite tanks resulting in the accumulation of another
10 + days.
It should be mentioned that these requested time extensions with the interim and completion milestones are
compatible with the North Holl y & South Holl y Ozone Project startup sequences. Your consideration of thi s
request is appreciated
Respectivel y,
~e ~~
Sr. Project Manager
