<br />Limited Asbestos Survey Report <br />411 E 20th Street <br />Santa Ana, CA 92706 <br /> <br />12631 Imperial Hwy Suite A225. Santa Fe Springs, CA 90670 <br />www.terraeng.com <br /> <br />I. Executive Summary and Introduction <br /> <br />On January 19, 2026, Terra Environmental conducted a limited asbestos-containing material <br />(ACM) survey at 411 E 20th Street Santa Ana, CA 92706, to identify regulated materials that may <br />be disturbed during the planned renovation. The inspection was performed by Mr. Oscar Sanchez <br />Jr., an AHERA Certified Asbestos Building Inspector (DOSH# CA-015-05, CSST Trainee), under <br />the supervision of Mr. Israel Monsalvo, a California DOSH Certified Asbestos Consultant (CAC# <br />04-3551, Exp. 05/20/2026). Both meet the training and accreditation requirements of EPA AHERA <br />(40 CFR 763) and SCAQMD Rule 1403 for asbestos surveys. <br /> <br />Bulk samples of suspect materials were collected and analyzed by an NVLAP-accredited laboratory <br />via Polarized Light Microscopy (PLM) in accordance with EPA Method 600/M4-82-020. Analytical <br />results found no ACM or ACCM in the sampled materials. Therefore, no asbestos abatement is <br />required for the project as currently defined. However, Cal/OSHA Title 8 CCR §1529, EPA NESHAP <br />(40 CFR 61, Subpart M), and SCAQMD Rule 1403 require that any unidentified suspect material <br />discovered during work be evaluated prior to disturbance. This survey meets the asbestos <br />inspection requirements of SCAQMD Rule 1403 for renovation projects. <br /> <br /> <br />II. Scope of Work <br /> <br />This limited survey targeted only the building materials anticipated to be impacted by renovation <br />activities at the subject property. The scope included: <br /> <br /> Visual inspection of accessible areas to identify suspect ACM. <br /> Bulk sampling of representative materials classified into homogeneous areas per AHERA <br />protocols. <br /> Layer-by-layer analysis in an accredited laboratory using PLM with a 1% detection limit and <br />application of the California ACCM threshold (≥0.1% asbestos). <br /> Regulatory comparison to determine handling requirements under federal, state, and local <br />standards. <br /> <br />This inspection was conducted in accordance with SCAQMD Rule 1403 requirements for <br />renovation projects, including a thorough inspection of all accessible suspect asbestos-containing <br />materials within the scope of work, sampling by an AHERA-accredited inspector, and laboratory <br />analysis by an NVLAP-accredited facility. <br /> <br /> <br /> <br />Regulatory Framework – Overview <br /> <br />Applicable regulations include: <br /> <br /> Federal: OSHA Asbestos in Construction (29 CFR 1926.1101), EPA NESHAP for Asbestos (40 <br />CFR 61, Subpart M), EPA AHERA (40 CFR 763), USDOT Hazardous Materials Regulations (49 <br />CFR 171–180).
