Subject: RE: TSA Remedy Semiannual Reporting
Importance: Normal
DEQ has reviewed the proposed changes to the reporting method and timing for the East Multnomah County project (ECSI #1479) and approves these changes. Beginning with the report due at the end of March 31, 2009 reporting period, reports will be submitted semi annually and all data related to the TSA will be incorporated into a single semi annual report. I will place a copy of this email in the site file as a record that the reporting for this site will be modified from that described in the Consent Order WMCSR-NWR-96-08.

Subject: TSA Remedy Semiannual Reporting
Hello Mavis,
This email follows our earlier communications regarding discontinuation of all TSA Remedy annual and quarterly reporting, and their replacement with semiannual TSA reporting to eliminate duplicate reporting. We propose this to begin with data for the period ending March 31, 2009. Per your prior request, the semiannual reports would be “robust” versions of prior quarterly reports and would include data for the 6-month reporting period, plus historical VOC data on CD for reference. Five year performance evaluation reporting would continue, with the next one due in 2013.
For semiannual reports, we propose the following:
· One joint TSA remedy semiannual report per reporting period,
· Semiannual reporting periods to include: October 1 through March 31 and April 1 through Sept. 30 (for consistency with prior annual reporting periods),
· Discontinued quarterly and annual reporting and replacement semiannual reporting would begin with the period ending March 31, 2009,
· Semiannual reports would be submitted to DEQ within 60 days of the end of reporting period (consistent with prior quarterly reporting).
· Each semiannual report would be similar in content, summarizing significant actions taken, remedy performance, recommendations, and actions planned, incorporating key elements of the prior quarterly and annual reports.
· Each report will include: tabled extraction rate, water level, and water quality data; hydrographs; contoured groundwater elevation and TCE data; laboratory and validation reports, and historical VOCs (on compact disc).
· To assist with ongoing remedy management, DEQ approvals, remedy changes, and significant actions/issues for each reporting period will continue to be documented clearly, as will itemization of significant correspondence with DEQ.
On behalf of Cascade and Boeing, we seek DEQ’s formal approval of this change, which will modify Attachment B, Section 1 (page B-13) of DEQ’s Order on Consent No. WMCSR-NWR-96-08 for the TSA Remedy.
Sincerely, Sarah
