GLOSSARY OF TERMS
Guide to Reading and Understanding Your Laboratory Report The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative.

Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name, Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received.

Abbreviations and Definitions
(dry) Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils].

MDL Method Detection Limit.

MQL (dry) Method Quantitation Limit.

MQL Method Quantitation Limit.

RDL Reported Detection Limit.

Rec. Recovery.

RPD Relative Percent Difference.

SDG Sample Delivery Group.

SDL Sample Detection Limit.

SDL (dry) Sample Detection Limit.
(S)
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media.

U Not detected at the Sample Detection Limit.

Unadj. MQL Unadjusted Method Quantitation Limit.

Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported.

Dilution
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor.

Limits
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges.

Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control sample. The Original Sample may not be included within the reported SDG.

Qualifier
This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.

Result
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte.

Uncertainty
(Radiochemistry) Confidence level of 2 sigma.

Case Narrative (Cn)
A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.

Quality Control
Summary (Qc)
This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material.

Sample Chain of
Custody (Sc)
This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis.

Sample Results (Sr)
This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported.

Sample Summary (Ss) This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis.

Qualifier Description
J The identification of the analyte is acceptable; the reported value is an estimate.

J4 The associated batch QC was outside the established quality control range for accuracy.

J7 Surrogate recovery cannot be used for control limit evaluation due to dilution. 1 Cp

1 RSB Project No. 2201006
PR-2024-001701 (GPA, SPA, RZ, DR) Exhibit 13 - EIR Addendum and appedices Historical Use Summary
Based on available historical information, the Subject Property was an undeveloped land at least until 1907. A Dwelling unit was depicted on the Subject Property in 1908. The existing commercial building was developed on the Subject Property in 1939. Since then, the Subject Property has been used for commercial purposes.

Based on the review of the City Directory, the Subject Property has been an automotive facility at least from 1930s till 1965, and 1991 till the present, and a Rug Cleaning facility at least from 1966 until 1969. Tetrachloroethylene was identified as the chemical used during rug cleaning operations. These solvents, even when properly stored and disposed of, can be released from these facilities in small, frequent releases through floor drains, cracked concrete, and sewer systems. Chlorinated solvents are highly mobile chemicals that can easily accumulate in the soil. Reviewing local agency records is not likely to produce any additional information as the dry cleaners operated during a time period with little or no regulatory oversight. Additionally, any auto repair facilities are an environmental concern due to their typical usage of hazardous substances such as petroleum and hydraulic fluids and halogenated solvents. During the site reconnaissance, RSB observed staining in the auto repair area. Based on the historic use of the property as a rug cleaning facility, long-term (55 years) association of the Subject Property with automotive repair and servicing operations, unknown house keeping practices the potential exists that spills/leaks might have occurred and not reported; and impacted the subsurface condition at the Subject Property. This is considered a Recognized Environmental Condition (REC).

2 RSB Project No. 2201006
PR-2024-001701 (GPA, SPA, RZ, DR) Exhibit 13 - EIR Addendum and appedices Findings and Conclusions
RSB has performed a Phase I ESA in general conformance with the scope and limitations of ASTM Standard E1527-13 for the Property located at 4468 Brockton Avenue, Riverside, Riverside County, California 92501, the Subject Property. Any exceptions to or deletions from this practice are described in Section 10.0 of this report.

1. This assessment has revealed the following RECs in connection with the Subject Property:
• Based on the review of the City Directory, the Subject Property has been an automotive facility at least from 1941 till 1965, and 1991 till the present, and a Rug Cleaning facility at least from 1966 until 1969. Tetrachloroethylene was identified as the chemical used during rug cleaning operations. These solvents, even when properly stored and disposed of, can be released from these facilities in small, frequent releases through floor drains, cracked concrete, and sewer systems. Chlorinated solvents are highly mobile chemicals that can easily accumulate in the soil. Reviewing local agency records is not likely to produce any additional information as the dry cleaners operated during a time period with little or no regulatory oversight. Additionally, any auto repair facilities are an environmental concern due to their typical usage of hazardous substances such as petroleum and hydraulic fluids and halogenated solvents. During the site reconnaissance, RSB observed staining in the auto repair area. Based on the historic use of the property as a rug cleaning facility, long-term (55 years) association of the Subject Property with automotive repair and servicing operations, unknown housekeeping practices the potential exists that spills/leaks might have occurred and not been reported; and impacted the subsurface condition at the Subject Property. This is considered a Recognized Environmental Condition (REC).

2. This assessment has revealed no evidence of HRECs in connection with the Subject Property.

3. This assessment has revealed no evidence of CRECs in connection with the Subject Property.

4. This assessment has revealed no evidence of BERs in connection with the Subject Property.

Non-ASTM Scope Items
• Due to the age of the Subject Property building (pre-1989), it is likely that asbestos-containing materials (ACMs) are present at the Subject Property. Overall, potential ACMs (PACMs) were observed to be in good condition. Actual material samples would need to be collected in order to determine if ACMs are present.

De Minimis Environmental Conditions
• RSB observed staining on the concrete flooring which appears from onsite operations. No floor drains, cracks, penetrations, or other potential pathways to the subsurface were identified at these locations. Based on the observed condition of the concrete flooring, this staining is considered a de minimis environmental condition.

3 RSB Project No. 2201006
PR-2024-001701 (GPA, SPA, RZ, DR) Exhibit 13 - EIR Addendum and appedices Recommendations
Based on the conclusions, RSB recommends the following:
• RSB recommends a limited subsurface investigation be conducted in order to determine if the identified REC areas have adversely impacted the subsurface soil and/or groundwater conditions at the Subject Property.
• The PACM be managed safely under an Operations and Maintenance (O&M) Program until removal is dictated by renovation, demolition, or deteriorating material condition. Should renovations or demolition be required, PACMs would need to be sampled to confirm the presence and/or absence of asbestos prior to any renovation or demolition activities to prevent potential exposure to workers and/or building occupants.

On January 19, 2022, Ms. Alexis Caballos, a Site Inspector with RSB, conducted a site reconnaissance to assess the possible presence of petroleum products and hazardous materials at the Subject Property. RSB’s investigation included a review of aerial photographs, a reconnaissance of adjacent properties, background research and a review of available local, State and Federal regulatory records regarding the presence of petroleum products and/or hazardous materials at the Subject Property.

RSB contracted Environmental Risk Information Services Ltd. (ERIS) to perform a computer database search for local, State and Federal regulatory records pertaining to environmental concerns for the Subject Property and properties near the Subject Property (refer to Regulatory Records).

1.1 Purpose
The purpose of the ESA is to identify Recognized Environmental Conditions (RECs), Controlled Recognized Environmental Conditions (CRECs) and Historical Recognized Environmental Conditions (HRECs) and de minimis conditions as defined by ASTM E1527-13.

The term REC is defined as the presence or likely presence of any hazardous substances or petroleum products in, on, or at a property: (1) due to 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 CREC is defined as a recognized environmental condition resulting from a past release of hazardous substances or petroleum products that has been addressed to the satisfaction of the applicable regulatory authority (for example, as evidenced by the issuance of a no further action letter or equivalent, or meeting risk-based criteria established by regulatory authority), with hazardous substances or petroleum products allowed to remain in place subject to the implementation of required controls.

The term HREC is defined as a past release of any hazardous substances or petroleum products that has occurred in connection with the Subject 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.

The term de minimis condition is defined as a condition that generally does 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 RECs or CRECs.”
The term Business Environmental Risk (BER) is defined as a risk which can have a material environmental or environmentally-driven impact on the business associated with the current or planned use of a parcel of commercial real estate, not necessarily limited to those environmental issues required to be investigated as defined by ASTM.

This Phase I ESA was also performed to permit the User to satisfy one of the requirements to qualify for the innocent landowner, contiguous property owner, or bona fide prospective purchaser limitations on Phase I Environmental Site Assessment

4.0 ENVIRONMENTAL RECORDS

4.1 Standard Environmental Record Sources
Information from standard Federal and state environmental record sources was provided through Environmental Risk Information Services Ltd. (ERIS). Data from governmental agency lists are updated and integrated into one database, which is updated as data is released. This integrated database also contains postal service data in order to enhance matchings for the Subject Property. Records from one government source are compared to records from another to clarify any ambiguities for the Subject Property. The demographic and geographic information available provides assistance in identifying and managing risk. The accuracy of the geocoded locations is approximately +/-300 feet.

In some cases, location information supplied by the regulatory agencies is insufficient to allow the database companies to geocode facility locations. These facilities are listed under the Orphans section within the ERIS report. According to the ERIS report, orphan facilities were not identified.

In addition, as recommended by ASTM Standard E1527-13, the standard Federal, State, and Tribal Environmental Record sources within the ERIS report were utilized to identify potential on-site and/or off-site RECs, CRECs, and HRECs. If identified, the relative listed REC(s), CREC(s), and/or HREC(s) is discussed below. A copy of the ERIS Report has been included in Regulatory Records Appendix of this
report.

5.4 Sanborn Fire Insurance Maps
Sanborn Maps were originally created for assessing fire insurance liability in urbanized areas throughout the United States. The maps include detailed records regarding town and building information in approximately 12,000 U.S. towns and cities from 1867 to 1970 and have become a valuable tool for historical researchers. From an environmental standpoint, the map collection is a useful aid in documenting historical property developments of environmental concern such as dry-cleaning facilities, gas stations, manufacturing plants, etc.

RSB reviewed the collection of Sanborn Fire insurance maps from Environmental Risk Information Services Ltd. (ERIS) on January 12, 2022. Sanborn map coverage was available for the Subject Property.

RSB did not observe evidence of spills, staining or leaks due to the above mentioned substances. Based on the good condition of the above mentioned substances, it is not expected to represent a significant environmental concern.

RSB identified few compressed gas cylinders containing oxygen and argon. The compressed gas cylinders were observed to be stored in an upright position and were secured to the concrete wall with steel chains.

These materials appeared to be securely stored and properly labeled, and no evidence of significant leaks, spills or materials mismanagement was observed at the time of reconnaissance.

Aboveground and Underground Storage Tanks (AST/UST)
RSB observed one (1) 110-gallons AST containing waste oil and one (1) 110-gallons AST containing antifreeze located in the hazardous waste enclosure, adjoining the west corner of the building. RSB did not observe evidence of leaks or staining on the floor associated with the chemicals. RSB recommends secondary containment be provided for the storage tanks. Based on the observed good condition of the aboveground storage tanks, it is unlikely to consider them as an environmental concern.

There were no signs of leak observed near transformers. Based on the observed condition of the transformers, it is unlikely to consider them as an environmental concern.

RSB observed one (1) air compressor located in the west corner of the storage container. There were no signs of leak observed near the air compressor. Based on the observed good condition of the air compressor, it is unlikely to consider it as an environmental concern.

The Subject Property is currently equipped with, one (1) 12,000 lbs hydraulic lift, one (1) 7,000 lbs hydraulic lift, and two (2) 9,000 lbs hydraulic lifts were located in the service area, on the northwest portion of the building, east corner of the building and in the center of the property respectively. The hydraulic equipment associated with existing aboveground hydraulic lifts and forklift appeared to be operational, and no significant staining or other evidence of a release of hydraulic fluid was observed in the vicinity of this equipment. Based on the observed good condition of the hydraulic lifts, it is unlikely to consider them as an environmental concern.

Interior Stains or Corrosion other than from Water
RSB observed staining on the concrete flooring which appears from onsite operations. No floor drains, cracks, penetrations, or other potential pathways to the subsurface were identified at these locations. Based on the observed condition of the concrete flooring, this staining is considered a de minimis environmental condition.

Exterior Stained Soils or Pavement
RSB observed minor staining on pavement in the parking lot of the Subject Property. The staining appeared superficial and limited in extent, consistent with routine leakage from automobiles. RSB does not consider the staining an environmental concern in connection with the Subject Property.

7.0 ASTM NON-SCOPE CONSIDERATIONS
RSB also assessed the subject property for the presence of Asbestos Containing Materials (ACMs), Radon, Lead-Based Paint and Mold Evaluation.

7.1 Asbestos containing Material (ACM)
Asbestos is a mineral fiber that has been used commonly in a variety of building construction materials for insulation and as a fire-retardant. Because of its fiber strength and heat resistant properties, asbestos was used in roofing shingles, ceiling and floor tiles, insulation products, asbestos cement products, and a host of other building materials. ACM is often classified as either friable or non-friable. Friable ACM, when dry, can be crumbled, pulverized, or reduced to powder by hand pressure. Non-friable ACM can be crumbled, pulverized, or reduced to powder during machining, cutting, drilling, or other abrasive procedures. When asbestos-containing materials are damaged or disturbed by repair, remodeling or demolition activities, microscopic fibers become airborne and can be inhaled into the lungs, where they can cause significant health problems. Friable ACM is more likely to release fibers when disturbed or damaged than non-friable ACM.

RSB conducted a limited visual screening for the presence of ACM at the Subject Property. The potential for the presence of ACM was evaluated based on the age of the improvements, dates of renovation, and other relevant information. For this assessment, materials listed in the USEPA Guidance Document:

Managing Asbestos in Place - A Building Owner’s Guide to Operations and Maintenance Programs for Asbestos-Containing Materials, which were installed prior to 1989, are suspected of containing asbestos. It should be noted that, while less likely, asbestos may still be found in current building materials, particularly non-friable products, such as sheet vinyl flooring, vinyl floor tiles, floor tile mastic, joint compound, asbestos-cement board and roofing materials.

Findings: Due to the age of Subject Property building (pre-1989), it is likely that asbestos containing materials (ACMs) are present at the Subject Property.

Overall, potential ACMs (PACMs) were observed to be in good condition. Actual material samples would need to be collected in order to determine if ACMs are present. According to the US EPA, ACMs and PACMs that are intact and in good condition can, in general, be managed safely under an Operations and Maintenance (O&M) Program until removal is dictated by renovation, demolition, or deteriorating material condition. Should renovations or demolition be required, PACMs would need to be sampled to confirm the presence and/or absence of asbestos prior to any renovation or demolition activities to prevent potential exposure to workers and/or building occupants.

7.2 Radon
Radon is a naturally occurring colorless, odorless gas that is a by-product of the decay of radioactive materials potentially present in bedrock and soil. The USEPA guidance action level for annual residential exposure to radon is 4.0 picoCuries per liter of air (pCi/L). The guidance action level is not a regulatory requirement for private owners of commercial real estate, but is commonly used for comparison purposes to suggest whether further action at a building may be prudent.

A preliminary evaluation of the potential for concerns relating to radon was made using the USEPA Map of Radon Zones. The USEPA Map is based solely on averages in order to identify areas in the country with the potential for elevated indoor radon levels. Elevated levels of radon have been found in all radon zones.

33 RSB Project No. 2201006
PR-2024-001701 (GPA, SPA, RZ, DR) Exhibit 13 - EIR Addendum and appedices action level does not mean a specific property does not have elevated levels of radon. The evaluation considered the location of the Property, previous test results, if available, type of construction and usage of the Subject Property.

Findings: Radon sampling was not requested as part of this assessment. According to the United States EPA, the radon zone level for the Riverside County is Zone 2. Zone 2 counties have a predicted average indoor radon screening level between 2 and 4pCi/L with a moderate potential for radon gas.

7.3 Lead-Based Paint (LBP)
Lead was added to paint as a pigment, to speed drying, increase durability or to resist moisture. Although lead improves paint, it was found to pose a health hazard, particularly to children under the age of six, whose bodies are still developing. A paint is considered LBP if it contains lead equal to or exceeding 1.0 milligram per square centimeter or 0.5 percent by weight, or 5,000 parts per million (ppm) by weight.

A preliminary evaluation for the presence of LBP was conducted. The evaluation was based on the age of the improvements, the extent of renovations, property usage, and past analytical testing, if available.

The Consumer Product Safety Commission banned the use of lead in paint in 1978, 16 CFR 1303. Most manufacturers, however, had ceased using lead well before this time. Paint applied after 1978 is not considered suspect LBP.

A comprehensive LBP survey was not conducted as part of this assessment. Conclusions are based on observations of representative areas only. A finding that LBP is not a significant concern cannot be interpreted as the building is free of LBP.

Findings: Due to the non-residential use of the Subject Property building, LBP is not a concern.

7.4 Mold Evaluation
As part of this assessment, RSB performed a limited visual inspection for the conspicuous presence of suspect mold growth. A class of fungi, molds has been found to cause a variety of health problems in humans, including allergic, toxicological, and infectious responses. Molds are decomposers of organic materials, and thrive in humid environments, and produce spores to reproduce, just as plants produce seeds.

When mold spores land on a damp spot indoor, they may begin growing and digesting whatever they are growing on in order to survive. When excessive moisture or water accumulates indoors, mold growth will often occur, particularly if the moisture problem remains undiscovered or unaddressed. As such, interior areas of buildings characterized by poor ventilation and high humidity are the most common locations of mold growth. Building materials including drywall, wallpaper, baseboards, wood framing, insulation, and carpeting often play host to such growth. Moisture control is the key to mold control. Molds need both food and water to survive; since molds can digest most things, water is the factor that limits mold growth.

The EPA recommends the following action to prevent the amplification of mold growth in buildings:
• Fix leaky plumbing and leaks in the building envelope as soon as possible; • Watch for condensation and wet spots. Fix source(s) of moisture problem(s) as soon as possible; • Prevent moisture due to condensation by increasing surface temperature or reducing the moisture level in air (humidity). To increase surface temperature, insulate or increase air circulation. To reduce the moisture level in air, repair leaks, increase ventilation (if outside air is cold and dry), or dehumidify (if outdoor air is warm and humid);
• Keep heating, ventilation, and air conditioning (HVAC) drip pans clean, flowing properly, and unobstructed;

PR-2024-001701 (GPA, SPA, RZ, DR) Exhibit 13 - EIR Addendum and appedices • Vent moisture-generating appliances, such as dryers, to the outside where possible; • Maintain low indoor humidity, below 60% relative humidity (RH), ideally 30-50%, if possible; • Perform regular building/HVAC inspections and maintenance as scheduled; • Clean and dry wet or damp spots within 48 hours; and
• Do not let foundations stay wet. Provide drainage and slope the ground away from the foundation.

Findings: RSB observed the accessible interior areas of the Subject Property structure for the presence of conspicuous suspect mold or observed water intrusion or accumulation. RSB did not observe any conspicuous visual or olfactory indications of the presence of water intrusion or suspect mold growth.

This activity was not designed to discover all areas, which may be affected by mold growth on the Subject Property. Rather, it is intended to give the Client an indication as to whether or not conspicuous (based on observed areas) suspect mold growth is present at the Subject Property. This evaluation did not include a review of pipe chases, HVAC systems or areas behind enclosed walls or ceilings.

• RSB recommends a limited subsurface investigation be conducted in order to determine if the identified REC areas have adversely impacted the subsurface soil and/or groundwater conditions at the Subject Property.
• The PACM be managed safely under an Operations and Maintenance (O&M) Program until removal is dictated by renovation, demolition, or deteriorating material condition. Should renovations or demolition be required, PACMs would need to be sampled to confirm the presence and/or absence of asbestos prior to any renovation or demolition activities to prevent potential exposure to workers and/or building occupants.

10.0 ASSUMPTIONS, LIMITATIONS AND EXCEPTIONS

10.1 Significant Assumptions
RSB assumes the Subject Property has been correctly identified by the User, designated representative of the User, Subject Property owner or operator, and/or the designated representative of the Subject Property owner or operator. RSB assumes that the User, designated representative of the User, Subject Property owner or operator, and/or the designated representative of the Subject Property owner or operator used good faith in answering questions about and providing information for the Subject Property.

RSB assumes the direction of groundwater is consistent with the contours depicted on the United States Geological Survey (USGS) topographic map covering the Subject Property, unless otherwise specified by actual well data for the Subject Property or properties in the area, or RSB's experience and knowledge of the area.

10.2 Limitations and Exceptions
The findings and conclusions contain all of the limitations inherent in these methodologies that are referred to in ASTM Standard E1527-13. Specific limitations and exceptions to this ESA are more specifically set forth below:
• RSB only accessed the accessible areas of the Subject Property. • Data gaps are defined as a lack of or inability to obtain information required by ASTM E1527-13 despite good faith efforts. No significant data gaps were identified that would affect the ability of the environmental professional to identify recognized environmental conditions in connection with the Subject Property.
• The scope of work completed was designed solely to meet the needs of RSB's Client. RSB shall not be liable for any unintended usage of this report by another party. Additionally, based on the ASTM Standard Practice, the ESA is only valid if completed within 180 days of an acquisition or the transaction necessitating the ESA, unless updated in accordance with terms outlined within the Standard Practice.
• No ESA can wholly eliminate uncertainty regarding the potential for RECs in connection with a Subject Property. This ESA was designed to reduce but not eliminate uncertainty regarding the existence of such conditions in a manner that recognizes reasonable limits of time and cost. RSB has completed this ESA in accordance with generally accepted consulting practices, and makes no other warranties, either expressed or implied, as to the character and nature of such services or product.
• An ESA is intended to be a non-intrusive investigation and generally does not include sampling or testing of air, soil, water, or building materials. No destructive testing was completed and concealed areas, such as behind walls or within machinery, were not accessed. • Information needed to complete the ESA is based on personal interviews, government records, published resources, and various historical documents. Accuracy and completeness of information varies among information sources and is often inaccurate or incomplete. An environmental professional is not required by the ASTM Standard Practice to verify independently the information provided but may rely on information provided unless the environmental professional has actual knowledge that certain information is incorrect or unless it is obvious that certain information is incorrect based on other information obtained by or otherwise actually known to the environmental professional.

Depending on its past, present or future intended use, the Subject Property under review may or may not be subject to regulation and permitting under environmental and health and safety laws, such as, but not limited to, the Clean Air Act, the Clean Water Act, the Solid Waste Disposal Act, the Occupational Safety and Health Act, and other federal, state and local regulations. RSB assumes no responsibility or liability respecting regulatory permitting or compliance issues.
