Dudash, Joe <br />From: Ward, Jason <br />Sent: Monday, June 09, 2008 5:06 PM <br />To: Dudash,Joe <br />Subject: RE: Bruce Park Dam <br />Joe - Thank you for your comments on the draft letter. I tend to agree in all aspects and will make a few revisions. I'm in <br />the field this week, but will make every attempt to get the revised letter to you by the end to the week. <br />Jason Ward <br />From: Dudash, Joe <br />Sent: Monday, June 09, 2008 4:08 PM <br />To: Ward, Jason <br />Subject: RE: Bruce Park Dam <br />We have reviewed your draft letter dated June 6, 2008. We appreciate your prompt response. The content of the letter is <br />what we expected. However, we do have one request for clarification. In the last sentence of the first page, your office <br />requests periodic measurement of the dam's pliezometers and survey monuments. The letter references your agency's <br />May 16, 2006 letter. The May 16, 2006 letter, in turn, references your agency's June 11, 2003 letter. Rather than <br />referencing previous letters, the Division requests that your agency include in your current letter some guidance, perhaps <br />with specifics, concerning a proposed dam monitoring program. <br />On page 3 of Exhibit 18, "Seismic Monitoring-Summary Statement", which was included in Bowie's response letter dated <br />May 12, 2008, the operator states that there will be an inspection of the dam if a threshold event is exceeded. No other <br />information is given as to the nature of the dam inspection. Also, It does not mention monitoring of the dam for baseline <br />data or if the threshold event is not exceeded. Since you inspect dams, it would be helpful if Bowie and the Division knew <br />what kind of data and at what frequency of collection would be appropriate. I think Bowie needs specific guidance in <br />establishing this monitoring program for the dam and it would save time if they knew upfront what was expected of them. <br />Does this sound possible or would you rather have Bowie propose the specifics? <br />From: Ward, Jason <br />Sent: Monday, June 09, 2008 9:35 AM <br />To: Dudash, Joe; Brown, Sandy <br />Subject: Bruce Park Dam <br />Joe and Sandy - Attached is a draft letter regarding comments from our office on the Bruce Park landslide monitoring <br />program presented by Bowie Resources for PR-10. If this meets your needs, I will finalize and send it. Please call with <br />any questions (970) 249-6622. <br />Thanks, <br />Jason Ward <br /><< File: 060608_ltr to_Dudash DRAFT.pdf >> <br />Jason P.
