RE: Phase I Environmental Site Assessment

2300 Columbus St.

Bakersfield CA 93306


ALFA Environmental Assessment Services is pleased to provide you with the attached Phase I Environmental Site Assessment for the above referenced subject site (hereafter referred to as the “Property”). The work performed for this project included: a professional site reconnaissance, interviews, and detailed research of: regulatory agency files; aerial photographs; historical maps; previous environmental assessment reports at nearby sites, and a review of the regulatory environmental database listings for the Property and surrounding area.


“I, Valentina Constantinescu, declare that, to the best of my professional knowledge and belief, I meet the definition of Environmental Professional as defined in 312.10 of {40CFR 312}”, and “I have the specific qualifications based on education, training, and experience to assess a property of the nature, history, and setting of the subject property. I have developed and performed All Appropriate Inquiries (AAI) in conformance with the standards and practices set forth in

{40CFR Part 312}.”


Sincerely,


ALFA Environmental Assessment Services

PROJECT SUMMARY


We have performed a Phase I Environmental Assessment in conformance with the scope and limitations of ASTM Practice E1527-21 of the Property located at 2300 Columbus St. (APN 45222616), Bakersfield CA 93306. Any exceptions to, or deletions from, this practice are described in this report.


The goal of the processes established by the practice for conducting an environmental site assessment is to identify recognized environmental conditions (RECS). Recognized environmental conditions indicate the presence or likely presence of any hazardous substances or petroleum products on a property under conditions that indicate an existing release, a past release, or a material threat of a release into structures on the Property or into the ground, ground water, or surface water of the Property. The term is not intended to include de minimis conditions that generally do not present a threat to human 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. Conditions determined to be de minimis are not recognized environmental conditions.


The Property is located south of Oakdale Rd., north of Sequoia-Kings Canyon FreeRd. (180), and east of Burlington Northern Santa Fe Railroad within a residential and Thornton area of Bakersfield, Bakersfield County, California.


The Property totals approximately 0.43 acres and is vacant land.


The Assessor Parcel Number (APN): 45222616 (Bakersfield County).


There was no evidence of improper storage, usage, or disposal of hazardous waste or other chemicals.


No indication of potentially hazardous material disposal with the solid waste was noted during ALFA reconnaissance. No stains or significant odors were noted. Nonhazardous waste at this site is not considered a significant concern to this investigation.


No on-site water wells or springs were observed during the Property reconnaissance.

No settling ponds, lagoons, surface impoundments, wetlands or natural catch basins were observed at the Property during this investigation.


No evidence of water supply, irrigation, oil, injection, or dry wells was observed on the Property.


No evidence of underground storage tanks (USTs) or aboveground storage tanks (ASTs) were observed on Property.


The subject Property was not identified in the regulatory database reports.


The adjacent properties were not identified in the regulatory database reports.


A large number of properties were identified within 1-mile radius in the regulatory database reports. The most significant nearby properties were identified in the following regulatory database reports:


VAPOR ENCROACHMENT SCREENING


The Vapor Encroachment Screening (VES) Standard (ASTM E2600-10) may include a two-tiered screening process. Initially, the Tier 1 VES focuses on known or suspected contaminated properties located within the area of concern (AOC). The VES process does not evaluate the potential for vapor intrusion (VI) of subsurface vapors. Evaluation of VI conditions requires field sampling, and is not included in ASTM E1527-21.


Solvents, gasoline, and other volatile compounds are routinely used at auto repair shops, gas stations and at manufacturing companies. A thorough review of the subject Property and nearby environmental cases (all Closed Cases), including site history, geological, hydrogeological, and contaminant extent review,

indicated contamination at the nearby fuel stations, auto repair shops, and/or other listed sites is confined to these sites.


Operations at the adjacent properties do not present a vapor encroachment condition to the subject Property. Based on the findings, vapor migration from adjacent properties is not expected to represent a significant environmental concern at this time. Copies of significant figures and documents regarding the nearby listed sites are attached.


Findings and Opinions


The goal of the processes established by the practice for conducting an environmental site assessment is to identify:


Recognized environmental condition (REC) refers to the presence or likely presence of any hazardous substances or petroleum products in, on, or at a property: due to release to the environment; under conditions indicative of a release to the environment; or 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 threat to human 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. Conditions determined to be de minimis are not

recognized environmental conditions. Conditions that present a REC are those involving hazardous substances/petroleum products that we cannot rule out a release to the subsurface without analytical data, for example: USTs, dry cleaners, industrial/manufacturing, solvent usage, septic system on an industrial property, etc.


Historically, subject Property area has been undeveloped/vacant land.

According to the Sanborn Fire Insurance Maps (see attachments), in 1906, a stable and a water tank is depicted in the west portion of the subject property and the rest of the Property was vacant land.


Since the early 1920’s houses are depicted on subject Property area. In 1950, a storage structure is depicted at #2012 and dwellings and some auto garages between #2014 and #2070 E Harvey Rd. In the 1970’s, there are no significant changes at subject Property. Since the early 1980’s the subject Property area and adjacent areas to the east-northeast and west-southwest are depicted as vacant land (along future freeRd.)


There are no businesses significant to this Phase I ESA listed on site.


ALFA did not identify any recognized environmental conditions for the subject Property during the course of this assessment.


Historical Recognized Environmental Condition (HREC) refers to 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 use criteria established by a regulatory authority, without subjecting the property to any required controls.


ALFA did not identify any historical recognized environmental conditions for the subject Property during the course of this assessment.


Controlled recognized environmental conditions (CREC) refers to 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.

ALFA did not identify any controlled recognized environmental conditions for the subject Property during the course of this assessment.


OPINIONS AND RECOMMENDATIONS


This assessment has revealed no evidence of Recognized Environmental Conditions (RECS), Controlled RECs (CREC), and Historical RECs (HREC) associated with the subject Property.


An environmental issue is defined as an environmental concern which does not qualify as a REC, but which may warrant further discussion. Operations at the adjacent properties do not present a vapor encroachment condition to the subject Property. Vapor migration is not expected to represent an environmental concern at this time.

No further investigation of the subject Property is recommended at this time.
