Phase I Environmental Site Assessment 1.0 INTRODUCTION 1.1 PURPOSE OF ASSESSMENT SoundEarth Strategies, Inc. (SoundEarth) was commissioned by Teutsch Partners LLC to complete a Phase I Environmental Site Assessment (ESA) of the Lona Vista Apartments Property located at 931 Broadway Avenue in Everett, Washington (the Property). The primary purpose of this ESA is to identify, to the extent feasible, recognized environmental conditions (RECs) resulting from the use, manufacture, storage, and/or disposal of hazardous or toxic substances that could affect the future acquisition and/or development of the Property. This study is intended to satisfy the level of effort often referred to as "all appropriate inquiry" in the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), 42 USC § 9601, with the objective of allowing Teutsch Partners LLC to qualify for the landowner liability protections afforded by CERCLA. 1.2 METHODOLOGY/SCOPE OF WORK This Phase I ESA was conducted in accordance with procedures outlined in American Society for Testing and Materials (ASTM) E1527-13, Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process. ASTM E1527-13 uses the term "recognized environmental conditions" to assess environmental risks associated with a property. The term is defined as "the presence or likely presence of any hazardous substances or petroleum products in, on, or at a property: (1) due to any release to the environment; (2) under conditions indicative of a release to the environment; or (3) under conditions that pose a material threat of a future release to the environment."The term is not intended to include de minimis conditions that generally do not present a material risk of harm to public health or the environment and that generally would not be the subject of an enforcement action if brought to the attention of appropriate governmental agencies. Two additional categories of RECs are included in ASTM E1527-13: historical recognized environmental conditions and controlled recognized environmental conditions. ASTM E1527-13 uses the term "historical recognized environmental condition" (HREC) to define environmental risks associated with "...a past release of any hazardous substances or petroleum products that has occurred in connection with the property and has been addressed to the satisfaction of the applicable regulatory authority or meeting unrestricted residential use criteria established by a regulatory authority, without subjecting the property to any required controls." A "controlled recognized environmental condition" (CREC) is defined as "...a REC resulting from a past release of hazardous substances or petroleum products that has been addressed to the satisfaction of the applicable regulatory authority...with hazardous substances or petroleum products allowed to remain in place subject to the implementation of required controls." The scope of work for this Phase I ESA included the following tasks: • A review of various sources of historical information dating back to 1921, which are identified in Section 4.0, including reverse city street directories (such as those published by Polk, Inc.), Sanborn Fire Insurance Maps (Sanborn Maps), Kroll Atlases, local planning and assessment records, and available aerial photographs of the Property and vicinity.
