Reference: Quality Assurance Project Plan (QAPP) For IBM Essex Junction, VT Industrial Wastewater Sludge De-Lis ting (approved on 01/27/2011)

Subject: Submission of Analytical Results as Outlined in the above referenced QAPP

Dear Ms. Leitch:

The IBM Corporation, Essex Junction, VT semiconductor manufacturing facility (VTD002084705) is providing the an alytical results required by th e approved Quality Assurance Project Plan For IBM Essex Junction, VT I ndustrial Wastewater Sludge De-Listing. These analytical results are being provided to EPA Re gion 1, so the evaluation phase of the federal delisting process for IBM’s F006 Industrial Wa stewater Treatment (IWTP) sludge can be completed.

As you indicated in your note to Candi ce Callahan, of my staff, on March 8 th 

### , 2011, when an analytical result of less than the detection limit wa s reported, half of the detection limit was used in our calculations. The minimum, average, a nd maximum values reported in Attachment A are calculated based on this a ssumption, when applicable.

If you have any questions concerning this in formation, please contact one of the following members of my staff: Candice Callahan by telephone at 769-0579 or electronically at ccallaha@us.ibm.com David Kost by telephone at 769-2761 or electronically at dlkost@us.ibm.com

Sincerely,

Tim Baechle Manager of Energy, Environmen tal, and Chemical Programs

## Report Summary of Qualifiers and Notes

Samples were received at the laboratory with a temperature of 15.2 degrees Celsius. Samples must be received in a cooler with sufficient ice to attain a temperature of 6 degrees Celsius or below. Samples must not be frozen.

SBV: Analysis performed by subcontract ed laboratory, VHG Labs. The complete subcontracted report has been appended to this report.

QS-: Indicates surrogate rec overy was below laboratory acceptance limits, a ttributed to sample matrix interference.

M - : The laboratory fortified matrix (LFM) analysis indicates a potential negative bias in the reported value.

QA-: QA/QC associated with this anal ysis did not meet laboratory acceptance limits indicating the results may be biased low.
