4.7 Owner, Property Manager, and Occupant Information The Site is currently owned and managed by the David A Colton Trust. The Site is currently utilized for commercial/office purposes by multiple tenants. 4.8 Reason for Performing Phase I ESA The client has commissioned this Phase I ESA as part of a proposed acquisition and future redevelopment. The Phase I ESA is also being completed to assist the client in complying with 40 CFR Part 312. 4.9 Proceedings Involving the Site The client is unaware of pending, threatened, or past litigation and administrative proceedings relevant to hazardous substances or petroleum products in, on, or from the Site. The client is also unaware of notices from any governmental entity regarding any possible violation of environmental laws or possible liability relating to hazardous substances or petroleum products in connection with the Site. 4.10 Other Provided Documents The following prior Phase I and II ESAs pertaining to the Site were provided by the client: • Stantec. 2021. Phase I Environmental Site Assessment, 1901 and 1971 East 4th Street and 515 and 525 Cabrillo Park Drive, Santa Ana, California. June 18, 2021. • Stantec. 2018. Phase II Environmental Site Assessment, 1901 and 1971 East 4th Street and 515 and 525 Cabrillo Park Drive, Santa Ana, California. July 13, 2021. The Phase I ESA was performed in general accordance with ASTM Standard E1527-13 and consisted of a site reconnaissance, interviews with knowledgeable personnel, review of historical documentation, and review of federal, state, and local regulatory databases. Findings, relevant information, and conclusions presented in the Stantec Phase I ESA include: • The Site was historically utilized for agricultural (i.e. orchards) purposes from circa 1938 until 1966. Stantec noted that agricultural use can be a potential concern due to the possible use of pesticides and herbicides. Therefore, Stantec recommended collecting shallow soil samples to evaluate for potential residual organochlorine pesticides (OCPs) and arsenic and lead concentrations that may exist at concentrations of potential concern relative to Site development. The aforementioned was identified as a recognized environmental condition. • Stantec also noted that asbestos -containing materials and lead -based paint may be present in on -Site building materials and testing should be performed before any major renovations or demolition. This also included the potential presence of petromat in the asphalt paved parking lot. This was noted as a non-ASTM consideration. Based on the above findings, a Phase II ESA was performed by Stantec. The general scope of work and associated findings and conclusions are as follows: • Fifteen (15) soil borings were advanced throughout the exterior portions of the Site and to a maximum depth of three (3) feet below the ground surface. Soil samples were collected from each boring at 0.5-1.0 feet, 1.5-2.0 feet, and 2.5-3.0 feet. The soil samples collected from 0.5- 1.0 feet were initially submitted for laboratory analytical testing that included OCPs by EPA test Method 8081A and arsenic and lead by EPA test Method 6010B.
