As required by the above referenced RCRA Order, specifically VI number 3 (page 9 of 22), thefollowing is the monthly progress report. If you should require a copy of past monthly activities,please contact me. The progress report items are numbered with the first three letters of themonth. This month's items are as follows:

Current Monthly Progress ReportRepublic DUMPCo continues to make progress in completing the tasks outlined in the WorkPlan. Three drill rigs are on site advancing boreholes, setting casings, and/or installing wells.These include the following: 1 Percussion Hammer (API000), 1 drill and drive (T4W), and aSonic (GP300 RS).

Jan.l: The exploratory borings were started on March 13, 2000. The following is the status ofthese exploratory borings. It should be noted that when a monitoring well has beeninstalled, the prefix for the location designation changes from GH to MW, and when themonitoring well has been developed, the prefix will be changed to PW. This is reflectedbelow. Furthermore, when a boring has been classified as being "abandoned," this meansthe boring as been plugged with bentonite and sealed. Once a boring as been classified inthis progress report as being "abandoned," the boring will not be included in the nextmonths progress report.

MW-1 A: Stopped at 102 feet below ground surface (bgs) at bed rock contact, and amonitoring well has been installed. (No water has been detected in this monitoring wellsince installation).

GH-2E2: This boring was drilled to 330 bgs, and while being advanced, communicationwith 2C2 was noticed. Air was coming out of 2C2. Drilling was stopped, and EPAcontacted. It was decided that this boring would be grouted up to the bottom of PW-2C2,and a well installed. This was done in order to save 2C2 if sloughing had occurred. Thecalculations indicate that some sloughing did occur above 265 bgs. This boring will becompleted as a monitoring well.

GH-3C: Barber Rig has advanced this boring to 500' bgs at this location. A seal wasinstalled at this zone, but current data indicate that the seal was not installedappropriately. In a June 12, 2001, email to EPA, Republic has proposed a possiblesolution to this problem.

RE: Monthly Progress Report - October, 2001Order RCRA 7003-09-99-0005NOV/Order CWA-3 09-9-99-14

As required by the above referenced RCRA Order, specifically VI number 3 (page 9 of 22). thefollowing is the monthly progress report. If you should require a copy of past monthly actn ;tiesplease contact me. The progress report items are numbered with the first three letters of themonth. This month's items are as follows:

Current Monthly Progress ReportRepublic Services of Southern Nevada (RSSN) continues to make progress in completing thetasks outlined in the Work Plan. Currently, an air rotary (T4W) and a Schramm are drilling,setting casing and/or installing wells. A Smeal 5T is onsite for well development and sampling

Oct.l: The exploratory borings were started on March 13, 2000. The following is the status ofthese exploratory borings. It should be noted that when a monitoring well has beeninstalled, the prefix for the location designation changes from GH to MW, and when themonitoring well has been developed, the prefix will be changed to PW, This is reflectedbelow. Furthermore, when a boring has been classified as being "abandoned," this meansthe boring as been plugged with bentonite and sealed. Once a boring as been classified inthis progress report as being "abandoned," the boring will not be included in the nextmonths progress report. An * indicates that the status of this item has changed.

i

MW-1 A: Stopped at 102 feet below ground surface (bgs) at bed rock contact, and amonitoring well has been installed. (No water has been detected in this monitoring \\ ellsince installation).
