Progress Review Meeting<br />

Page 2<br />

approvals are with the CHPRC 100-K Fire Protection Engineer pending their approval of this<br />

system. Additional request has been made for CAD drawings of this configuration by the Fire<br />

Protection Engineer. WCH has followed up on status and has resolved CHPRC concerns and<br />

requests. Currently just waiting on the permits to be issued by CIIPRC. Discussed 150 gpm<br />

restrictor to be installed at the hydrant tie-in as well as an additional restrictor at the water high<br />

tank. Permnits scheduled to be complete by 1/14/2010. Still waiting on permits from CI-PRC.<br />

WCH following up. Hydrant permit is in hand, waiting for excavation permit. Plan to perform<br />

work on water line on an off shift work day, pushing for Friday 2/19/2010. Excavation permit is<br />

complete. Discussed that 100-K water will be shut-off this weekend. Friday work is pending.<br />

Further discussed backflow preventer versus air-gap installation requirements. DDI is pursuing<br />

additional changes to the water system tie-in. WCH met with CHPRC again on 2/22/20 10. DDI<br />

to complete system construction while new permits are pending. Decision has been made to<br />

utilize the existing permits in place. DDI will begin to get materials on site to support installation<br />

of water tie-in to support installation date of Friday, 3/19/2010. Work inside the fence next door<br />

needs to be complete by the end of the weekend of the 19th so not to disrupt their work. DDI<br />

indicated system should be operational the week of March 22. DDI waiting on materials, flow<br />

restrictors, tanks, calcium chloride. Underground installations completed in the 100-K area. DDI<br />

does not yet have parts on-site to complete the above ground installations to complete the tie-ins.<br />

DDI to provide information/details for additional flow requests. DDI to prepare as-built<br />

information prior to energizing system. High tank is in place and operational. DDI is having<br />

some issues with float valve that they are continuing to work through. Getting this system<br />

operational inside the burial ground needs to be a priority. DDI is working through a request by<br />

Watts for additional GPM. DDI is considering bringing in another sub to complete the water<br />

system project (4/20). DDI is evaluating a recalculation of water system requirements from Watts<br />

and will forward to WCH after review. Watts has been instructed by DDI to continue installation<br />

of the stabilization injection system related to the water system. WCH requests a P&ID of the<br />

water system (4/27). DDI is finalizing the P&ID and will submit this week (5/4). DDI has run<br />

calcs on the injection system pump production and recognizes that the pump proposed by Watts is<br />

significantly undersized. Therefore, the P&ID will not be submitted until this issue is resolved.<br />

WCH does not have a defined injection rate for the use of calcium chloride. (5/11) The use of<br />

calcium chloride or other soil bonding agents are a performance specification, not a specific<br />

requirement of WCH. No change. (5/18) Injection system to be complete by Wednesday May<br />

26, plan to demonstrate on Tuesday June 1. DDI has no plans to utilize a tank (as shown on<br />

previous sketch) or any type of pump to increase pressure. (5/25) System equipment<br />

configuration is complete, still need to test the remote water cannons with the current pressures.<br />

Discussed pressure needs for operating the system, additional pumps, tanks, etc. On 5/27, system<br />

was tested and it took 14 minutes for a water truck to fill (approximately 285 gpm). (6/1) DDI is<br />

sending a letter to Watts to rework system for increased pressure. (6/8) DDI to submit letter,<br />

request for clarification for intent of water supply. (6/15) No change. (6/22) WCH has not<br />

received letter from DDI about water supply. (6/29) DDI states they send letter on 6/23, but<br />

WCH STR has not received copy. (7/6) WCH received letter 7/12. WCH PM is following up<br />

with CHPRC before responding to letter. (7/14) WCH PM followed up with the CHPRC Deputy<br />

Fire Marshal about the permit. They hope to have updated information to us by the end of the<br />

week. WCH discussed how using additional percentage of calcium chloride could control dust<br />

and use less water. It was also suggested that DDI look into bringing an additional water tower<br />

on site that could be filled at the start of the day to provide additional water. (7/20) DDI has<br />

submitted WCH suggestions to sub-tier for proposal if there is no increase in water permitted at<br />

the hydrant restrictor. (7/27) DDI has not received a response from WCI on alternative<br />

dust/water suppression chemicals or methods. CHPRC is restricting water on their site. They are
