Hanson Engineer Metropolitan Council Environmental Services Industrial Waste & Pollution Prevention Section 390 North Robert Street St. Paul, Minnesota RE: 4th Quarter 2016 Special Discharge Report MCES Permit No Central Avenue NE, Minneapolis, MN Permit Duration: December 1, 2015 to November 30, 2018 Dear Ms. Hanson: On behalf of Ashland, Inc. (Ashland), Groundwater and Environmental Services, Inc. (GES) has prepared this Special Discharge Report (SDR) for the groundwater remediation system located at 2900 Central Avenue NE in Minneapolis, Minnesota. This SDR covers the reporting period from October 1, 2016 through December 31, 2016 for the Metropolitan Council Environmental Services (MCES) permit number This permit covers the disposal of treated groundwater. During the reporting period, the groundwater discharged from the remediation system was in compliance with MCES discharge permit limits. If there are any questions regarding the information presented in this report, please contact me at , Ext. 3171, or James Vondracek with Ashland at Sincerely, GROUNDWATER AND ENVIRONMENTAL SERVICES, INC. Brian J. Deering Senior Project Manager Attachments: 4th Quarter 2016 Special Discharge Report Laboratory Analytical Reports Cc: Mr. James Vondracek, Ashland, Inc.

22 #=QL# QUALIFIERS DEFINITIONS DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot. ND - Not Detected at or above adjusted reporting limit. J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit. MDL - Adjusted Method Detection Limit. PQL - Practical Quantitation Limit. RL - Reporting Limit. S - Surrogate 1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method The result for each analyte is a combined concentration. Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values. LCS(D) - Laboratory Control Sample (Duplicate) MS(D) - Matrix Spike (Duplicate) DUP - Sample Duplicate RPD - Relative Percent Difference NC - Not Calculable. SG - Silica Gel - Clean-Up U - Indicates the compound was analyzed for, but not detected. N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method The result reported for each analyte is a combined concentration. Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes. TNI - The NELAC Institute. WORKORDER QUALIFIERS WO: [1] Trip blank provided by Pace, in error, contains Methanol, not DI /HCl. Analysis of this blank would not be applicable to the water samples. ANALYTE QUALIFIERS CL L0 L2 M1 P5 R1 c2 The continuing calibration for this compound is outside of Pace Analytical acceptance limits. The results may be biased low. Analyte recovery in the laboratory control sample (LCS) was outside QC limits. Analyte recovery in the laboratory control sample (LCS) was below QC limits. s may be biased low. Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery. The EPA or method required sample preservation degrades this compound, therefore acceptable recoveries may not be achieved in sample matrix spikes. RPD value was outside control limits. Acid preservation may not be appropriate for the analysis of 2-Chloroethylvinyl ether. Date: 10/14/ :01 AM without the written consent of. Page 13 of 16

41 #=QL# QUALIFIERS DEFINITIONS DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot. ND - Not Detected at or above adjusted reporting limit. J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit. MDL - Adjusted Method Detection Limit. PQL - Practical Quantitation Limit. RL - Reporting Limit. S - Surrogate 1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method The result for each analyte is a combined concentration. Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values. LCS(D) - Laboratory Control Sample (Duplicate) MS(D) - Matrix Spike (Duplicate) DUP - Sample Duplicate RPD - Relative Percent Difference NC - Not Calculable. SG - Silica Gel - Clean-Up U - Indicates the compound was analyzed for, but not detected. N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method The result reported for each analyte is a combined concentration. Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes. TNI - The NELAC Institute. WORKORDER QUALIFIERS WO: [1] Samples were received outside of the recommended temperature range of 0-6 degrees Celsius. The samples were received from the field on ice, indicating the cool down process had begun. BATCH QUALIFIERS Batch: [M5] ANALYTE QUALIFIERS A matrix spike/matrix spike duplicate was not performed for this batch due to insufficient sample volume. D6 D8 H6 c2 The precision between the sample and sample duplicate exceeded laboratory control limits. The sample and duplicate results for this parameter are less than 5 times the reporting limit, the RPD may not be statistically valid. Analysis initiated outside of the 15 minute EPA required holding time. Acid preservation may not be appropriate for the analysis of 2-Chloroethylvinyl ether.

ND - Not Detected at or above adjusted reporting limit. J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit. MDL - Adjusted Method Detection Limit. PQL - Practical Quantitation Limit. RL - Reporting Limit. S - Surrogate 1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method The result for each analyte is a combined concentration. Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values. LCS(D) - Laboratory Control Sample (Duplicate) MS(D) - Matrix Spike (Duplicate) DUP - Sample Duplicate RPD - Relative Percent Difference NC - Not Calculable. SG - Silica Gel - Clean-Up U - Indicates the compound was analyzed for, but not detected. N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method The result reported for each analyte is a combined concentration. Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes. TNI - The NELAC Institute. ANALYTE QUALIFIERS P5 c2 The EPA or method required sample preservation degrades this compound, therefore acceptable recoveries may not be achieved in sample matrix spikes. Acid preservation may not be appropriate for the analysis of 2-Chloroethylvinyl ether. Date: 12/20/ :07 PM without the written consent of. Page 16 of 19
