Exhibit 6. Opinions: Basis and Reasons for Opinions

Changes from June 2018 Cost Estimate to November 2018 Cost Estimate

Data collected during the July 2018 sampling by Wood Environmental and Infrastructure Solutions, Inc. (“Wood”), as well as other information presented in the October 2018 Remedial Investigation Report (RIR) prepared by Wood, were evaluated for impacts on the cost and duration of the remedial design for which estimates were given in my June 2018 Supplemental Expert Report. The following additional data were used as inputs for updating the June 2018 estimates.

The results from the hydraulic testing performed in May 2017 and July 2018 and reported in the RIR caused significant changes in the conceptual design upon which this cost estimate is based. The hydraulic testing results indicate that there are four primary intervals in the aquifer, referred to in the RIR as the shallow aquifer, intermediate aquifer, deep (C zone) aquifer and deep (D zone) aquifer, respectively. The shallow and intermediate parts of the aquifer appear to have groundwater velocities that are similar to those used in the prior cost estimates; therefore, no changes were made in the shallower treatment areas (“A” and “B” intervals in the cost estimate). The deeper portions of the aquifer are identified as bedrock. The “C zone” appears to have the flow characteristics of a system dominated by fracture flow. The calculated average linear velocities in the “C zone” locations are very high – higher than would be typically amenable to treatment by bioremediation. The deepest location tested (MW-3D), which falls in the “D zone” aquifer, appears to have very little flow, with an estimated velocity of 0.009 ft/day, and may be reflective of competent rock. Using the cross sections prepared in the RIR and the hydraulic test data, the required height (thickness) of the treatment biobarriers at each line (Line 3, Line 5, and Line 6) was re-evaluated based on the amenability of the aquifer geology/hydrogeology to biological treatment. The total costs were revised by adjusting the parameters of each of these barriers. All biobarrier designs were adjusted based on the new information.

The area of high flow velocities, referred to as the deep “C zone” in the RIR, is not targeted for bioremediation in the revised design. Water upgradient of the site boundary is to be treated by the influx of clean, treated water from the shallower zones. Water in the deep C zone aquifer at the site boundary is either left to naturally attenuate in the reasonable likely case (RLC) or captured by pumping and then treated using the existing treatment system in the conservative case (CC). The pump and treat system is in place to serve solely as a form of hydraulic control and is not expected to materially accelerate the completion of remediation. The pump and treat system is expected to run as long as the biobarriers operate.

The effects of these changes were:

• Onsite RLC cost decrease from $19.5MM to $16.0MM • Onsite CC cost decrease from $62.3MM to $51.0MM • Offsite RLC cost decrease from $3.51MM to $2.05MM • Offsite CC decrease from $9.42MM to $7.3MM

The total previous costs for the RLC and CC were: $23.0MM and $71.7MM.

The total costs for the RLC and CC presently are: $18.1MM and $58.3MM.

C-19

My opinions are expressed to a reasonable degree of scientific certainty. I reserve the right to supplement my opinions based on, among other things, and additional materials that are provided by Corning.
