A. Air monitoring and Project Management shall be performed by a qualified and licensed environmental firm that has been hired by the General Contractor. The Building Owner or other representatives of the Building Owner shall not be held liable in any way for negligence, whereas it be intentional or unintentional on the part of the General

Contractor or the Abatement Contractor. The asbestos abatement activities are being performed prior to renovation.

B. The asbestos inspection was performed by AAA Environmental, 300 Henry Place, Spartanburg, SC 29303. The inspection report was relied upon for the Project Design.

If conditions has changed since the inspection was completed it the air monitoring and abatement contractor responsible to bring that change of condition to the General

Contractors attention. The Abatement Contractor is responsible for verifying information provided in the inspection report. If material is discovered during the process of abatement or demolition that was not identified in the survey, the Contractor should contact a third party licensed inspector to sample the material, or assume that it contains asbestos and follow all applicable regulations.

1.2 DECRIPTION OF THE BUILDING

The facility site contains one (1) building. This building is a typical commissary, large open area with food supplies, cashier stations at the front of the building, an open warehouse to the eastside of the building and loading docks at the back. Offices are located on a second floor mezzanine on the east side of the building.

The basement/crawlspace had no visual suspect asbestos containing materials. The mechanical room located in the upper mezzanine area of the building, had equipment covered with fiberglass insulation, sealed with a white covering, and off white mastic.

The mastic tested positive for asbestos containing material (ACM). In addition, there was ductwork in a crawlspace off the mechanical room. The ductwork was covered with fiberglass insulation and sealed with mastic. The fiberglass and mastic in this area tested nondetected for asbestos containing material (ACM).

The building has a new metal roof installed over an existing metal roof, slab on grade and a partial unfinished basement/crawlspace. The majority of the interior walls of the building consists of cement masonry unit construction and walls covered with a thin sheetrock and a textured covering. The sheetrock walls were tested by following surfacing sample protocols and tested as nondetected for asbestos containing material

(ACM).

The ceilings construction is a combination of laid-in place ceiling tiles, and all tested nondetected for asbestos containing material (ACM). The concrete slab flooring is covered with various types and colors of floor tile and mastic. The Beige 12” x 12” floor tile and mastic in the main section of the building tested positive for asbestos containing material (ACM). The other floor tiles and mastics located in various places within the building, tested as nondetected for asbestos containing material

(ACM).

All sampling was conducted following South Carolina Department of Health and

Environmental Control (SC-DHEC) asbestos regulations protocol.

1.20 AIR MONITORING

A. The General Contractor must hire a third party qualified and SC-DHEC licensed air-monitoring firm. The abatement firm, per SC-DHEC regulation, cannot hire the air-

AAA Environmental Page 17 of 23 monitoring firm. In addition, the air-monitoring firm is to have no affiliation with the abatement firm.

B. The air-monitoring firm will provide all background, daily, and clearance samples.

Background and daily monitoring can utilize Phase Contrast Microscopy (PCM) analysis. Nonfriable floor tile and mastic is recommended to have a PCM clearance.

Friable removal must have a TEM clearance or a variance requested to and granted by

SC-DHEC. Air Monitor will perform all visual inspections and clearances.

C. Background and daily area air monitoring: The purpose of the background and daily area air monitoring is to evaluate quality, resolve problems, and minimize the potential for the spread of contamination beyond the work area. In addition, the work of the air monitoring firm includes performance of the final visual inspection and testing to determine whether a space or a building has been adequately decontaminated. All daily air monitoring is to be done utilizing Phase Contrast Microscopy (PCM) except for

Final Clearance Monitoring as specified in the following paragraphs. The Air Monitor will perform the following tasks:

1. Perform continuous air monitoring, inspection and testing inside and outside the work area during actual abatement work to detect any faults in the work area isolation and any adverse impact on surrounding areas from work area activities.

2. Perform final inspection and testing of decontaminated areas or buildings at the conclusion of the abatement and clean-up work to certify compliance with decontamination standard.

3. All data, inspection results, and testing results generated by the Air Monitor will be available to the contractor for information and consideration. Contractor shall provide cooperation and support to the Air Monitor for efficient and smooth performance of their work.

4. Air Monitor will have daily logs onsite, calibration records for manometer, and a minimum of 4 working air pumps.

D. Monitoring and inspection results of the General Contractor’s Representative may be used to issue any stop removal orders to the contractor during abatement work and to accept or reject an area or a building as decontaminated.

E. This section also sets forth airborne fiber levels both inside and outside the work area as action levels, and describes the action required by the Contractor if an action level is met or exceeded.

F. Stop action levels:

AAA Environmental Page 18 of 23

1. Inside Work Area: Maintain an average airborne count in the work area of less than .05 f/cc. If the fiber counts rise above this figure for any sample taken, revise work procedures to lower fiber counts. If the Time Weighted Average

(TWA) fiber count for any work shift or 8 hour period exceeds the Stop Action

Level, stop all work except corrective action, leave pressure differential and air circulation system in operation and notify Air Monitor. After correcting cause of high fiber levels, do not recommence work for 24 hours unless otherwise authorized, in writing, by Air Monitor.

If airborne fiber counts exceed 0.1 f/cc cease all work except corrective action.

Notify Air Monitor. Do not recommence work other than corrective action for

24 hours unless otherwise authorized, in writing, by Air Monitor.

2. Outside Work Area: If any air sample taken outside of the Work Area exceeds

0.01 f/cc or the base line established by background air monitoring, immediately and automatically stop all work except corrective action. The Air Monitor will determine the source of the high reading and notify the Contractor in writing.

If the high reading was the result of a failure of Work Area isolation measures initiate the following actions:

a. Immediately erect new critical barriers to isolate the affected area from the balance of the building. Erect Critical Barriers at the next existing structural isolation of the involved space (e.g. wall, ceiling, and floor).

b. Decontaminate the affected area in accordance with Project

Decontamination Procedures.

c. Require that respiratory protection as set forth in Respiratory Protection be worn in affected area until area is cleared for re-occupancy in accordance with Final Clearance Monitoring.

d. Leave Critical Barriers in place until completion of work and ensure that the operation of the pressure differential system in the Work Area results in a flow of air from the affected area into the existing Work Area.

e. If the exit from the clean room of the personnel decontamination unit enters the affected area, establish a separate decontamination facility consisting of a Shower Room and Changing Room.

f. After Certification of Visual Inspection in the Work Area, remove critical barriers separating the work area from the affected area. Final air

AAA Environmental Page 19 of 23 samples will be taken within the entire area as set forth in Final

Clearance Monitoring.

3. If the high fiber reading was the result of other causes, initiate the corrective action as determined by the Air Monitor.

1.21 CONTRACTOR RELEASE CRITERIA FOR FINAL WORK AREA

CLEARANCE:

A. Visual inspection: Final Clearance Monitoring will not begin until the Asbestos

Abatement Work Area airborne asbestos structure concentrations have been reduced to the level specified and described in Project Decontamination is complete, the area has passed a thorough visual inspection by the Air Monitor and the Project Manager and successful completion of these requirements has been certified by the Air Monitor and

Project Manager.

1.22 METHOD OF FINAL AIR CLEARANCE ANALYSIS:

A. Transmission Electron Microscopy (TEM) clearance is required for all friable removal work when the project exceeds 3000 square feet, 1500 lineal feet, or 656 cubic feet.

1. To determine if the elevated airborne asbestos structure concentration encountered during abatement operations has been reduced to the specified level, the Air Monitor will secure samples and analyze them according to the following procedures per designated areas.

2. Analytical Sensitivity for TEM analysis as set forth in the analytical method used and/or the AHERA regulation.

3. TEM samples will be secured as indicated below:

B. Transmission Electron Microscopy: FRIABLE REMOVAL WORK

Analysis will be performed using the analysis method set forth in the AHERA regulation 40 CFR Part 763 Appendix A. Samples will be sent by overnight courier for analysis by Transmission Electron Microscopy. Samples will not be carried on weekends, unless General Contractor has approved the additional cost, if samples are shipped on Friday they will arrive on the following Monday. Faxed and Verbal results will normally be available during the next working day after receipt of samples by the laboratory. All Transmission Electron Microscopy results will be available to the

Contractor.

In each homogeneous work area after completion of all cleaning work, a minimum of 5 samples will be collected and analyzed as follows:
