ADEQ Review of: 2"d Half 2016 Semi-Annual Groundwater Monitoring Report-and Notification of Statistically Significant Increases (SSis) Permit No. 0211-S3N-R2 AFIN: 41-00002 Document ID: 72464 Cross Reference: 71242

Dear Ms. Kilburn:

Terracon Consultants, Inc. is pleased to submit, on behalf of Domtar A.W., LLC, this response to the ADEQ correspondence dated September 6, 2017 concerning the 2"d Half 2016 Groundwater Monitoring Report and subsequent Notification of SSis.

The letter states:

The Arkansas Department of Environmental Quality Office of Land Resources (ADEQ) Regulated Waste Operations has reviewed the above document for the Domtar Class 3N Landfill. After review, ADEQ has the following comments:

Comments on 2"d Half 2016 Semi-Annual GWMR:

ADEQ Comment #1 As previously mentioned in the ADEQ letter dated November 10, 2016, because of the very high turbidity in MW-3R, it is suggested that low flow sampling at a rate at or below 100 mllmin be utilized instead of the well volumes method in an attempt to lower turbidity. As noted in the ADEQ letter dated June 10, 2016, redevelopment of this well may be needed if low flow does not rectify this issue.

Comment #1 response During the First Half 2017 sampling event, turbidity in MW-3R was below the acceptable level of 10 NTU when sampled. Additionally, modified low flow sampling technique was utilized at MW-3R in the sampling event.

ADEQ Comment #2 Please provide an explanation for the fluctuation of pH and constituent concentrations of the leachate samples from First Half 2016 and Second Half 2016 sampling events.

Comment #2 response

lrerracan

The facility is unaware of any operational procedures that could explain the fluctuations noted

above.

Comments on Letter Regarding Notifications of SSis:

ADEQ Comment #1 The alternate source demonstration for sulfate in MW-2 and MW-5 may not be valid. Please revise the data set for MW-3R, the background well, using only data since installation (Second Half 2011). In addition, it appears that the highest concentration for sulfate in MW-3R used in the statistical analysis, 78mg/L, is incorrect. Please correct this value to 7. 8 mg/L and re-run the interwell statistical analysis using the updated data set. Should this result in a statistically significant increase, please follow Reg. 22.1204(c).

Comment #1 response The historical database has been corrected for the above-noted event. The facility wishes to discuss with ADEQ the use of data predating the installation of MW-3R for background comparisons. Based on a review of the identified SSis and the ADEQ comments regarding the

submitted ASD, the facility will begin assessment monitoring in the next sampling event scheduled for November of 2017.

ADEQ Comment #2 Domtar should begin assessment monitoring during the next sampling event scheduled in November. For this event, all downgradient and side-gradient wells should be analyzed for all of Appendix 2 constituents, plus cadmium, phosphorous, and potassium as well as the normal list of constituents. If any constituents from Appendix 2 are detected, the facility should follow Reg. 22. 12 05 (b) for future sampling events.

Comment #2 response The facility will begin assessment monitoring in the next sampling event scheduled for November of 2017.
