Materials (MCM) may not be in the structure in areas that were not covered by this inspection.

This report has been prepared on behalf of and for the exclusive use of the West Texas VA Health Care

System for use in the herein described mold remediation of the site located at 2400 S. Gregg in Big Spring, Texas. This report and findings contained herein shall not, in whole or in part, be disseminated or conveyed to any other party, nor used by any other party in whole or in part, without the express written consent of

Texas Consulting Services.

SCOPE OF INITIAL MOLD ASSESSMENT

1. Texas Consulting Services will not be responsible for any mold containing materials (MCM) that were not found in the mold inspection of the site due to areas that were inaccessible or concealed.

Since the inspection is limited to areas that are accessible to the inspector and not enclosed or otherwise concealed from the inspection process and additionally that non-destructive testing is performed during the inspection, the owner is advised that remediation or demolition may discover additional MCM on site.

2. This protocol is based on the MCM inspection of the site and visible evidence discovered upon site walk. The laboratories used are AIHA certified and Texas Consulting Services assumes these analyses are true and correct but will not be responsible for their content.

3. Any damages done to the site will be the responsibility of the site owner. Some damage will occur as a part of the inspection process such as, but not limited to, painted surfaces, holes in walls or other cosmetic damage. Texas Consulting Services will not be responsible for these damages.

4. Theft from the site will not be the responsibility of Texas Consulting Services.

5. This inspection/protocol is not a warranty as to the absence of MCM in the completed project.

6. Neither Texas Consulting Services, its employees nor representatives have had, presently have, or contemplate having any interest in the subject property or are associated in any way with any party to this project.

7. This report is accurate only for the test date and/or remediation dates. Factors not limited to increased moisture levels or other activities on site may increase or decrease the amount of

MCM’s. TCS assumed no responsibility or knowledge of such factors.

8. Texas Consulting Services is not responsible for any activities beyond the date of inspection and/or remediation unless specifically contracted and outlined to do so.

9. No verbal statements by the inspector are to be considered a part of this inspection or report.

REMEDIATION PROTOCOL

2400 S. Gregg – Midland, TX

JOB SITE DESCRIPTION

This is a federal, Veterans Administration Health Care facility in Big Spring, TX. The property is owned and operated by the same. The facility/building in question is approximately 30,000 sq. ft., stand-alone structure consisting of a brick exterior with a sheetrock interior build out. The interior consists of concrete floors, carpet, VCT, sheetrock walls, and lay-in ceiling. The area included in this remediation project is the interior side of the exterior, perimeter walls of the Domiciliary Chief Office 103 and the common wall between Patient Rooms 152 & 154. This consultant has not yet been provided with a copy of the OSHA compliant asbestos survey.

ASSUMPTIONS AND CLARIFICATIONS

Contractor must be a currently licensed Mold Remediation Contractor with adherence to all TDLR Mold

Remediation Guidelines including contractor supervisor licensure, worker training, insurance and refreshers. Owner/management will address exact cause of water damage. The cause of damage appears to be long term damage from overhead water intrusion in the Domiciliary Chief Office 103 and plumbing leaks in the common wall of Patient Room 152 & 154. These areas are being addressed by the VA to remedy the moisture intrusion issues. The goal of this project is to successfully remediate the areas described herein according to this protocol. As a means of insuring damage will not reoccur the owner will repair the moisture intrusion issues in the facility from various sources. Owner/management will arrange those repairs, TCS and environmental contractors do not assume any reconstruction responsibility or knowledge. Tenant and/or owner management will move all loose articles, books, sensitive filing cabinets, computers, etc from containment areas prior to remediation. Any objects not removed from the room will be covered with min. 6 mil poly prior to any remediation. Environmental contractors will not be responsible for moving computer equipment. Owner will replace any AC filters discarded during remediation. Owner is to provide OSHA compliant asbestos survey prior to start date of desired remediation.

PROTOCOL

Description: This remediation will involve a remediation of the following:

• Approximately 129 sq. ft. of wall (sheetrock and original insulation) in interior wall cavities as noted for the remediation areas. Decontamination will include wet-wiping of all exposed structural elements with EPA approved bio-cide, HEPA-vacuuming of all contained items such as remaining walls, exposed studs, footings, wall systems and any material left in the room.

These shall run for a minimum of 24 hours before running post remediation sampling after removal is complete.

20. Perform clearance sampling as noted for these areas.

21. Contractor will not tear down containment until written clearance is issued by Consultant.

POST REMEDIATION SAMPLING AND CRITERIA

The contractor should contact the consulting company chosen to perform Post Remediation Clearances a minimum of 48 hours prior to completion of remediation to schedule clearance testing.

Post Remediation Clearance testing will be performed while walk-in enclosures and containments are in place. Devices used to provide negative pressure barriers will remain in use, along with any dehumidifiers or other climate control devices. Any critical barriers applied to openings will remain in place. Contractor may choose to ask for clearance of individual containments but must do so in writing a minimum of 48 hours in advance of containment completion and allow for a minimum of 24 hours of negative pressure HEPA-filtration scrubbing before post-remediation sampling is performed.

Consultant and Contractor will take photos of the completed work for documentation and inclusion in the Passed Final

Clearance Report.

The consultant will perform a visual assessment which will include:

• Determine if all mold contaminated materials identified in the investigation have been removed.

• The containment area(s) and staging area is free of dust and debris.

• All surfaces must be clean. Air sampling may not be performed during or immediately after a rain event.

• The work has been completed in compliance with the remediation protocol and remediation work plan.

Owner/management will provide written proof that a solution for the cause of the water/fungal damage is being sought, repaired and implemented prior to reconstruction and post-remediation sampling. If the visual assessment passes, air sampling will be conducted. Air sampling for mold will be performed using Air O Cell, Allergenco, Versa Trap 37 mm Spore Trap, or similar cassettes. Surface sampling will be performed using a nationally recognized surface lift method.

Prior to sampling, licensed consultant shall perform a laser particulate scan to determine if particle levels in the size range for mold/fungi spores is equal to or less than that of the same measurements in exterior air at the time of measurement. If particle levels are higher than exterior levels, further investigation may be necessary. This scan must be satisfactory prior to air and surface sampling.

One air and one surface sample from a hard surface will be collected in each enclosure/containment. One outside sample will be collected at about the same time outside the building. Outside sampling will be used for comparison. A minimum of two air samples and three surface samples from hard surfaces will be collected from random areas of the staging area during the post remediation sampling at about the same time (within ½ hour) of the sampling in each containment and the baseline exterior sample. Outside sampling will be used for comparison. Air sampling shall be performed in the normal breathing space of occupancy and/or in the remediated wall cavities of the perimeter of the facility.

If the areas do not pass the visual inspection, steps must be taken to correct the deficiencies. Then the area must be re-cleaned, inspected, and tested.

At the conclusion of air sampling, HEPA filter air machines and dehumidifiers (if in use) will be left in operation until analytical results confirm the remediation has been successfully completed and the contractor and owner have received verification of clearance in writing.

When addressing clearance criteria, it is important to note that the ACGIH (American Conference of Governmental

Industrial Hygienists) has not set a Threshold Limit Value (TLV) for microbial/fungi contamination and OSHA has not set a Time Weighted Average (TWA). It is also not expected that either will be addressed due to difficulties in establishing levels that result in health problems or what is normal (which varies greatly in different areas and seasons).

The Department of State Health Services (TDLR), OSHA, or EPA do not address or recognize “toxic” mold but recognize the hazard only by the size of contiguous growth. The industry standard is to compare exterior spore levels and types to those found in the interior of the building. Recently, the Mould and Bacteria Reviews printed a nationally recognized guideline for analyzing numerical data of non-viable and viable mould air samples. These are the standards by which the air in this building will be judged for clearance purposes and are summarized later in this section. However, clearance criteria for surface samples will be accordingly:

1. Any concentration (rare, medium or high) on the surface lifts of the following spore species will be determined as unsatisfactory and will warrant further investigation and/or remediation:

Stachybotrys and Chaetomium

2. Rare concentrations on the surface lifts of the following spore species will be determined as satisfactory and will not prohibit the consultant from issuing clearance: Aspergillus/Penicillium, Cladosporium, Bipolaris, Basidiospores, Ascospores, Alternaria, hyphal fragment or unidentifiable spores. Medium or High concentrations on a surface lift of this spore type will constitute a failed clearance. In addition, other spore types identified in exterior air counts at the same time of surface sampling but not included in this paragraph will be deemed acceptable in rare concentrations other than Stachybotrys and Chaetomium.

3. Medium concentrations on the surface lifts of the following spore types will be determined as satisfactory if found present during exterior air sampling during the same time period of surface sampling (within ½ hour) and will not prohibit the consultant from issuing clearance:

Cladosporium, Bipolaris, Basidiospores, Ascospores, Alternaria, hyphal fragment or unidentifiable spores. In addition, any other naturally occurring spore type identified in the exterior air at the time of air sampling will be scientifically analyzed to determine whether presence on the surface lift is acceptable in this concentration unless otherwise precluded in item

#1 of this section.

4. High counts of any spore type identified on a surface lift will warrant further investigation and/or remediation.

This surface sampling criteria may only be superceded or excluded only if sound scientific reasoning is provided in writing to both contractor and owner and the owner approves of this exclusion prior to the tear down of any enclosure/containment.

Clearance criteria for analytical air samples shall be in accordance with the Guidelines for Interpretation of

Numerical Data of Non-viable Airborne Mould Samples (located also in Appendix A of this report) as outlined in the April 2005 Issue #5, Part 1 and shall constitute a nationally recognized standard. These criteria are summarized in the following:

Guidelines for Interpretation of Numerical Data of Non-viable

Airborne Mould Samples

For a comprehensive assessment of the sample results, all the six steps require to be followed where applicable.

1. Consider the concentrations of spore types which may reach high concentrations in the outside environment (for example Ascospores, Alternaria/Ulocladium, Basidiospores, Cladosporium).

• If the total concentration of these spore types in the indoor air is lower than or equal to 1 to 1.4 times the outside concentration, i.e., Ic ≤ Oc x 1 (+0.4), then indoor source is unlikely (background level).

• If the total concentration of these spore types in the indoor air is lower than or equal to

1.6 (± 0.4) times the outside concentration, i.e., Ic ≤ Oc x 1.6 (± 0.4), then indoor source is possible and further investigations are required.

• If the total concentration of these spore types in the indoor air is more than twice the concentration in outside air, i.e., Ic > Oc x 2, then indoor source is likely and immediate further investigations are required.

2. Consider the concentration of Penicillium/Aspergillus spore types.

• If the difference in concentration between indoor air and outside air is lower than or equal to 300 spores/m3, i.e., Ic - Oc ≤ 300, then indoor source is unlikely (background level).

• If the difference in concentration between indoor air and outside air is greater than 300 spores/m3 but lower than or equal to 800 spores/m3 i.e., Ic - Oc > 300 ≤ 800, then indoor source is possible and further investigations are required.

• If the difference in concentration between indoor air and outside air is more than 800 spores/m3, i.e., Ic - Oc > 800, then indoor source is likely and further investigations are required immediately.

3. Consider the concentration of Chaetomium spp.

• If the concentration in indoor air is lower or equal to the concentration in outside air, i.e., Ic ≤ Oc, then indoor source is unlikely (background level).

• If the difference in concentration between indoor air and outside air is lower than or equal to 5 spores, i.e., Ic - Oc ≤ 5, then indoor source is possible and further investigations are required.

• If the difference in concentration between indoor air and outside air exceeds 5 spores, i.e., Ic - Oc > 5, then indoor source is likely and further investigations are required immediately.

4. Consider the concentration of Stachybotrys spp.

• If the concentration in indoor air is lower or equal to the concentration in outside air, i.e., Ic ≤ Oc, then indoor source is unlikely (background level).

• If the difference in concentration between indoor air and outside air is not more than 2 spores, i.e., Ic - Oc ≤ 2, then indoor source is possible and further investigations are required.

• If the difference in concentration between indoor air and outside air exceeds 2 spores, i.e., Ic - Oc > 2, then indoor source is likely and further investigations are required immediately.

5. Consider the concentration of various other unidentified fungal spores that do not belong to the basidiospore or ascospore types.

• If the difference in concentration between indoor air and outside air is not more than 600 spores/m3, i.e., Ic - Oc ≤ 600, then indoor source is unlikely (background level).

• If the difference in concentration between indoor air and outside air is greater than 600 spores/m3 but not more than 800 spores/m3, i.e., Ic - Oc > 600 ≤ 800, then indoor source is possible and further investigations are required.

• If the difference in concentration between indoor air and outside air is exceeds 800 spores/m3, i.e., Ic - Oc > 800, then indoor source is likely and further investigations are required immediately.

6. Consider the concentration of hyphal fragments.

• If the difference in concentration between indoor air and outside air does not exceed 150 fragments/m3, i.e., Ic - Oc ≤ 150, then indoor source is unlikely (background level).

• If the difference in concentration between indoor air and outside air is greater than 150 fragments/m3 but not more than 300 fragments/m3, i.e., Ic – Oc > 150 ≤ 300, then indoor source is possible and further investigations are required.

• If the difference in concentration between indoor air and outside air exceeds 300 fragments/m3, i.e., Ic - Oc > 300, then indoor source is probable and further investigations are required immediately.

When the indoor source is considered unlikely, the containments and staging area shall be considered satisfactory and will pass clearance. If further investigations are required, further cleaning and/or remediation will occur and re-clearance sampling will be performed.

When clearance is achieved, an acceptable encapsulant may be applied to seal and protect the building materials. Then the remaining polyethylene sheeting can be HEPA vacuumed, wet wiped, and removed for proper disposal.
