Fungal-Biological Hazard Remediation Protocol Irerracon Grand Theater ® 21 Lamar Street, Paris, Texas April 11, 2011 e Terracon Project No. 94117645 b) The pigeon related biological hazards and general contaminated debris in the second floor containment will be placed-in double bags and discarded as construction debris. The materials to be disposed as construction debris will be placed in double bags and the bags decontaminated prior to removal from the contained work areas. The quantity of fungal growth and biological-hazard material was estimated to cover 1,300 square feet of surface area. 11.0 PROJECT MODIFICATION The MAC, on an individual basis, will consider modifications designed to expedite or enhance the fungal remediation procedure. The MAC must approve deviations from the fungal remediation procedure described. 12.0 POST REMEDIATION VERIFICATION CRITERIA i. The project will be cleared by, 1) visual inspection, 2) tape lift analysis, and, 3) total bioaerosol analysis. The post remedial visual inspection and sample collection will be conducted while containments are in place and properly depressurized. The containment(s) may not be removed or completely depressurized until final clearance has been achieved and written, interim notice provided by the MAC to the MRC. ii. The visual inspection criteria will consist of an evaluation of the remediation area to determine if the remediation has been properly conducted in accordance with the project specifications, applicable state regulations and the fungal growth, defined biological-hazards, and extraneous debris within the work areas has been properly removed. iii. Tape lift samples shall be collected from representative locations of the decontaminated surfaces and analyzed by optical microscopy. Any area whose surface sample test does not meet post remediation criteria will be re-tested following additional cleaning of those areas. Tape lift sample analysis will be used to assess the cleaned wood ceiling deck/second floor. iv. Tape lift analytical clearance criteria will be based on an absence of fungal structures that indicate active fungal contamination. Trace quantities of random fungal spores indicate deposition while the presence of numerous somatic and reproductive structures indicates contamination. Fungal contamination is defined by the presence of somatic and reproductive tissue consistent with growth on the substrate. 1 a ®i{ itilte C-c?iE41 ®['.t=1l:i bit 6 MAC ' 0107/11-10-12 153
