Esus! 1si Shue(. <br />`, 301 <br />Lori Angtrlos, ::xllfurnis 90Ut 2 <br />78& 484% <br />env <br />Us 2204 <br />k1fo@i ricow,aIlf(ilia fits corn <br />wwrvr'u,eon �urtl ii lVEsn ts_oora <br />Pursuant to your request, we have prepared this proposal to conduct a Phase I Environmental Site <br />Assessment (ESA) for the parcel of land located at 202 S. Flower Street in Santa Ana, California and 2 <br />additional potential sites at an optional fee. It is our understanding that the subject property is currently <br />vacant land. The purpose of the Phase I ESA is to identify recognized environmental conditions <br />associated with soil and groundwater contamination at the subject property, <br />Scope of Work <br />The scope of work for a Phase I ESA has been established by ASTM Standard 1527-13 and consists of <br />four elements: records review, site reconnaissance, interviews, and report preparation. Please note that <br />pursuant to ASTM practice, our scope of services does not include any inquiries with respect to lead in <br />drinking water, regulatory compliance, cultural and historic resources, Industrial hygiene, health and <br />safety, ecological resources, endangered species, indoor air quality, or high voltage power lines. <br />Task 1: Records Review <br />A records review will be conducted to help identify recognized environmental conditions associated with <br />current and past uses of the property. The records review will include both environmental information <br />and historical use information readily available in public records. Information concerning recognized <br />environmental conditions associated with known nearby properties will be obtained using a computer <br />database records search in accordance with minimum search distances specified in the 2013 ASTM <br />Standard Practice for Environmental Site Assessments (the current standard for Phase i ESAS). <br />Online environmental agency file reviews will be conducted for unauthorized release sites that are <br />within the subject property, adjacent properties, or nearby properties and based on regional <br />hydrogeologic information would be expected to impact the subject property. Any file reviews will be <br />performed on a time and materials basis as authorized by the Client. Rincon provides this review on a <br />time and materials basis because the number of documents to be reviewed is unknown and can vary <br />Fn 11l r 1 11 11 1 11 i a!
