Its contents should not be relied upon by other parties without the expressed written consent of Earth Solutions NW, LLC (ESNW) and Polygon Northwest. Provided this report is still reliable (as determined by ESNW), ESNW may issue a third-party reliance letter to a party, other than Polygon Northwest, identifying in writing under the following conditions: that the third party, including Polygon Northwest and their successors and assigns, by such reliance, agree in writing to be bound by Terms and Conditions of the contract between Polygon Northwest and ESNW. Based on the intended use of the report, ESNW may require that additional work be performed and that an updated report be issued. Non-compliance with any of these by Polygon Northwest or anyone else will release ESNW from any liability resulting from the use of this report by any unauthorized party. 1.5 LIMITING CONDITIONS AND EXCEPTIONS A Phase I ESA is non-comprehensive by nature and is unlikely to identify all environmental problems or eliminate all risk. The report is a qualitative assessment. ESNW offers a range of investigative and engineering services to suit the needs of our clients, including more quantitative investigations. Although risk can never be eliminated, more detailed and extensive investigations yield more information, which may help you understand and better manage your risks. Since such detailed services involve greater expense, we ask our clients to participate in identifying the level of service, which will provide them with an acceptable level of risk. Please contact the signatories of this report if you would like to discuss this issue of risk further. ESNW performed this Phase I ESA in general accordance with the scope and limitations of the ASTM Standard Practice for Phase I Environmental Site Assessments: Environmental Site Assessment Process E 1527-13. No warranty, either express or implied is made. Environmental issues not specifically addressed in the report were beyond the scope of our services and not included in this Phase I ESA evaluation. Land use, site conditions (both on-site and off-site) and other factors will change over time. Since site activities and regulations beyond our control could change at any time after the completion of this report, our observations, findings and opinions can be considered valid only as of the date of the site visit. This report should not be relied upon after 180 days from the date of its issuance (ASTM Standard E-1527-13, Section 4.6). Earth Solutions NW,LLC
