SCHEDULE 6.1.23

ENVIRONMENTAL DISCLOSURES

Section 6.1.23(1), (2), (3):

1) In February 2007, the United States Environmental Protection Agency (“USEPA”) Region IV issued an Information Request to both Koppers Inc. (the “Company”) and Beazer East, Inc. (“Beazer East”) regarding the investigation and remediation of the Grenada, MI facility. Subsequent meetings resolved the issues related to the owned property, but issues were raised concerning the possible migration of contaminants off the property. The Company, in cooperation with Beazer East, conducted a series of investigations of off-site properties and an onsite stormwater pond and have conducted remediation activities in certain areas. USEPA completed additional offsite sampling downgradient and upgradient of the site in September 2018. The results of this work are being reviewed.

2) In July 2008, the Illinois EPA (“IEPA”) issued two Notices of Violation to the Company alleging improper management of hazardous materials at the Company’s Stickney, IL facility and demanding an investigation of the site. One Notice was for the owned portion of the site (38 acres) and one Notice was for the leased terminal. The Company, in cooperation with Beazer East, investigated both parcels. Remediation of the leased parcel is complete and IEPA issued a Return to Compliance Letter on the Notice related to the leased parcel. Investigation continues on the owned parcel which is under IEPA review.

3) In 2008, the Company was identified that it may be a potentially responsible party (“PRP”) at the LWD, Calvert City, KY CERCLA site. In 2009, USEPA accepted completion of remedial activities at the site. Subsequently, the Kentucky Department of Environmental Protection (“KYDEP”) identified additional potential work areas. In 2015, KYDEP approved the PRPs statement of work (capping and monitoring) and operation & maintenance (“O&M”) plan to address the identified areas, issued the Record of Decision (“ROD”), and executed the Agreed Order with the PRPs and the landowner to complete the incinerator remedy and O&M estimated at $6M. An Environmental Covenant was also filed on the property as required by the ROD and the Agreed Order. The work at the incinerator area was completed in 3Q and 4Q 2016. The construction completion report was submitted. Long-term O&M continues. The PRP Group’s and USEPA’s tolling agreements with non-settling parties expired on 12/31/2012 and the PRPs filed suit against non-settling parties at that time. The PRP Group has obtained funds from these previously non-settling parties.

4) In September 2009, the Company received a general notice letter notifying it that it may be a PRP at the Newark Bay, NJ CERCLA site. In January 2010, the Company submitted a response to the general notice letter asserting that the Company is a de minimus party at this site. The Company has not received a response to this letter.

[SIGNATURE PAGE TO THIRD AMENDMENT TO CREDIT AGREEMENT]

5) Groundwater sampling conducted in 2012 and 2013 at the Osmose, Inc. facility in Mt. Gambier, Australia indicated the presence of dissolved chromium at levels above applicable guidelines. Pursuant to a letter directive (2013) by the South Australia EPA (the “SAEPA”), the Company conducted further investigation at the site to assess the possible sources and extent of chromium in groundwater at the site. Following agency review, a groundwater extraction test program was conducted in 2017 to assess control of migration of chromium through pumping. The SAEPA requested a Voluntary Site Remedial Plan (“VSRP”) to implement the proposed pumping / gradient control program; final approval of the provided VSRP is pending.

6) Following the acquisition of Osmose, Inc., the Company, following up on the Company’s Millington, TN facility’s voluntary entry into the Tennessee Site Remediation Program (“SRP”), met with the Tennessee Department of Environment and Conservation (“TDEC”) to discuss the site’s status within the SRP and the scope of any possible additional work. In September 2015, TDEC approved a Work Plan for additional soil and groundwater characterization to better assess potential remedial actions. The investigation report and recommendations for further actions including treatment through subsurface injection was approved by TDEC in August 2016. The remedial implementation including installation of additional wells and subsurface injection of a remediation reagent was conducted in the 4th quarter of 2016. Success of the subsurface injection continues to be evaluated through ongoing groundwater monitoring.

7) In July 2015 the USEPA conducted a SPCC inspection at the Company’s Follansbee, WV facility. The facility was aware of and correcting all deficiencies noted during the inspection. In November 2015 the facility received a Consent Order from the Agency.

8) The Company has been named as one of the PRPs at the Portland Harbor, OR CERCLA site located on the Willamette River in Oregon. The Company formerly operated a coal tar pitch terminal near the site. The Company has responded to a USEPA information request and has executed a PRP agreement which outlines the process to develop an allocation of past and future costs among more than 80 parties to the site. The Company believes that it is a de minimus contributor at the site. USEPA issued the Record of Decision (“ROD”) on the site on January 13, 2017. The PRP group reviewed the ROD and certain PRPs are completing additional field sampling and data collection suggested in the ROD for use in subsequent design of the remedy. Additionally, a separate natural resources damages assessment (“NRDA”) is being conducted by a local trustee group. The NRDA is intended to identify further information necessary to estimate liabilities for remediation-based settlements of national resource damages (“NRD”) claims. The Company entered into a separate process to develop an allocation of NRD cost and has negotiated a cash-out settlement amount with the Trustee Group. A consent order is being developed to document the settlement between the Trustee Group and those parties engaged in early settlement. On February 6, 2017, the Yakama Nation, which had earlier dropped out of the Trustee coalition, filed suit against certain PRPs to seek recovery for response costs to releases at/from Portland Harbor site, and future response, assessment, and loss of natural resources in waterways downstream of the Portland Harbor site. The

[SIGNATURE PAGE TO THIRD AMENDMENT TO CREDIT AGREEMENT]

Company tendered the claim to Beazer East. At present the District federal court has recommended a stay of the case; a final ruling is pending.

9) On June 4, 2018, the Company received a letter from the USEPA concerning potential violations of the Clean Water Act observed during inspections and review of SPCC and Facility Response Plans at the Company’s facilities in Follansbee, WV; Green Spring, WV; and Clairton, PA. In addition, USEPA reviewed one facility’s compliance with an earlier consent order regarding above ground storage tank integrity testing. The Company continues to meet and correspond with USEPA to discuss and present relevant information related to the allegations.

10) By letter dated August 18, 2018, Alpine Waste & Recycling, Inc. (“Alpine”) notified the Company that Alpine has detected the presence of pentachlorophenol on its property adjacent to the Company’s Denver, CO facility, the presence of which Alpine claims was released from the Denver facility. Alpine also claimed it has incurred and will continue to incur damages in responding to this release. A similar letter was sent to Beazer East. Both the Company and Beazer East signed a tolling agreement with Alpine to facilitate continued discussions on the subject. The Company determined it did not use pentachlorophenol at the Denver plant and tendered the claim to Beazer East.

11) On September 4, 2018, the Company received a letter from NW Natural, as landlord, related to the Company’s formerly leased terminal site in Portland, OR alleging that the Company has certain remedial obligations at the site. The Company has advised NW Natural that the obligations related to remediation likely are the responsibility of Beazer East as a result of its former tenancy at the site pre-dating the Company’s tenancy at the site. The Company has tendered the claim to Beazer East.

12) On March 20, 2019, the Company received a letter from USEPA concerning a section 114 request under the Clean Air Act for the Company’s Galesburg, IL facility. The Company is sharing responsive documents to UESPA’s requests related to the site’s historical emissions and preparing to conduct emissions testing.

13) The disclosures in the other subparts of this Section 6.1.23 are incorporated by reference.

Section 6.1.23(7):

There may be structures, improvements, equipment, fixtures, impoundments, pits, lagoons, or aboveground or underground storage tanks which are owned by a Loan Party (by virtue of the acquisition of a Property), but that are not currently operated by a Loan Party may contain Regulated Substances other than conforming to the description contained in Section 6.1.23(7).

Section 6.1.23(9):

[SIGNATURE PAGE TO THIRD AMENDMENT TO CREDIT AGREEMENT]

4) SBA Shipyard, Jennings, LA – On October 13, 2016, the Company notified USEPA that the documentation provided on the site indicated that the relevant activities occurred prior to December 28, 1988 and therefore, were the responsibility of Beazer East. The Company also tendered the claim to Beazer East. The Company awaits further correspondence from USEPA.

5) Tank Car Corporation of America, Oreland, PA – In May 2011, the Company received a request for information from USEPA Region III for “Koppers Company” in connection with the Tank Car Corporation of America Inc. Site. In May 2011, the Company responded that supporting documents referenced in USEPA’s letter predated the sale from Beazer East and therefore the Company was not liable. The Company also tendered the claim to Beazer East. USEPA has not responded to date.

6) J&W Pallet and Drum, Atlanta, GA – In December 2007, USEPA Region IV issued an Information Request to Osmose, Inc. regarding the J&W Pallet and Drum Superfund Site. In its January 2008 response, Osmose, Inc. stated that it has no record of sending waste to J&W Pallet and Drum Company. The Company has had no further contact with USEPA regarding this matter.

7) Kentucky Wood Preserving Site, Winchester, KY - In October 2007, USEPA Region 4 issued an Information Request to Osmose, Inc. regarding the Kentucky Wood Preserving Site. In its response, Osmose, Inc. stated that, according to its records, it sold a product to Kentucky Wood Preserving between 1964 and sometime after 1980. The Company has had no further contact with USEPA regarding this matter.

8) Alternate Energy Resources, Augusta, GA - In November 2009, the Company received a request for information from USEPA Region IV in connection with the Alternate Energy Resources Superfund Site. In January 2010, the Company responded that supporting documents provided with the USEPA’s letter predated the sale from Beazer East and therefore the Company was not liable. The Company also tendered the claim to Beazer East. USEPA has not responded to date.
