Jansen, PE Project Manager 12000 Research Parkway Suite 152 Orlando, Florida 32826 Subject: Pre -Demolition Asbestos and Lead -Based Paint Survey And AST Evaluation Sebastian Municipal Airport 1225 Main Street Sebastian, Florida 32958. LPA Project: Sebastian Runway 09-27 SES Project Number 21594 Dear Mr. Jansen: SES Environmental, Inc. (SHS) has completed an asbestos and lead based paint survey of the J & S Aviation hangar building, and the Velocity Aviation hangar. In addition we conducted an evaluation of an aboveground storage tank at the airport. This project was performed in general accordance with the notice to proceed dated August 29, 2002. 1.0 ASBESTOS SURVEY The purpose in conducting this survey is to provide data regarding asbestos -containing materials (ACM) within the on-site buildings, which are scheduled for demolition, or to be moved 1.1 Observations SES performed the asbestos survey in August, 2002. During the sampling event, SES collected samples all areas of each facility that may have contained suspect materials. Areas inspected included above dropped in ceiling tiles, under carpet, and behind walls The buildings were in general, Butler style buildings that had been built out to include office areas. Ceilings in the apartment units accessed were painted sheetrock, or dropped in ceiling tile. Floors in the office areas were covered with carpet. The tiles in the J & S building were exposed. The floors in the work areas of each facility were concrete. Generally, the wallboard, flooring material, and roofing materials in the units were in good to poor 11285 Elkins Rd • Suite Irl • Roswell, GA 30076 • (770) 442-3352 • FAX (770) 442-812,1 a'd ,1096-SSB[Lob] opuera0 - dnoig ydI 841 e64:60 00 Bt des condition. Based on apparent building materials similarities, and date of construction, SES assumes that building materials such as textured ceiling and wall material, wallboard, and joint compomld observed and/or sampled in other units are homogeneous in the structures. 1.2 Asbestos Survey Mr. Slade L. Scoles, C.I.H. performed asbestos sampling in August, 2002. The sampling activities included a systematic visual review of accessible building areas to identify suspect ACMs. Samples of suspect ACMs were collected and analyzed by polarized light microscopy (PLM). A total of 11 suspect building material samples were collected and analyzed for asbestos by an accredited laboratory. In several instances, analysis by electron microscopy was required based on initial analysis by phase contrast microscope. During the sampling activities, information regarding each homogeneous material (i.e., material having the same color, texture, etc.) suspected to contain asbestos was recorded. Sample information recorded included sample nunmber, location information, amount of material present, material condition, and damage potential. The suspect material was then touched by hand to determine friability. Those materials easily crumbled or broken by hand pressure were categorized as friable. Those materials not severely damaged by fire, easily crumbled or broken by hand pressure were categorized as non -friable. Samples were collected by obtaining a representative sample of the suspect ACM by using clean sampling tools. The samples were placed into air -tight containers and labeled with a unique sample number. Samples were sent to Analytical Environmental Services, Inc. (AES) laboratory located in Atlanta, Georgia. The laboratory is accredited by the National Institute of Standards and Technology's (NIST) National Voluntary Laboratory Accreditation Progrun (NVLAP No. 101048-1) to perform sample analyses by Polarized Light Microscopy. The samples were analyzed using PLM with dispersion staining (PLM/DS) in accordance with the Environmental Protection Agency's (EPA) "Interim Method for the Determination of Asbestos in Bulk Samples" EPA-600/MA-82-020. This method identifies the asbestos type present in a material and quantifies the asbestos content on a volume percent basis. The EPA National Emissions Standard for Hazardous Air Pollutants (NESHAP) regulations (40 CFR Part 61 [revised]) defines friable -asbestos as "any material containing more than 1 percent asbestos as determined using Polarized Light Microscopy (PLM), that when dry, can be crumbled, pulverized, or reduced to powder by hand pressure." Additionally, if the content of friable asbestos is less than 10 percent as determined by PI K then the material must either be considered asbestos containing or the asbestos content must be verified by a more accurate Point Counting Method. Consequently, the result from the point counting analysis is the final determination of the concentration of asbestos found in the sample. 6'd T09c-SSa[L04J opuet.A0 - dnojg yd'l a41 eOS:60 aO ST daS The EPA National Emissions Standard for Hazardous Air Pollutants (NESHAP) regulations (40 CFR Part 61 [revised]) defines friable -asbestos as "any material containing more than 1 percent asbestos as determined using Polarized Light Microscopy (PLM), that when dry, can be crumbled, pulverized, or reduced to powder by hand pressure." Additionally, if the content of friable asbestos is less than 10 percent as determined by PLM, then the material must either be considered asbestos containing or the asbestos content must be verified by a more accurate Point Counting Method. Consequently, the result from the point counting analysis is the final determination of the concentration of the presence of regulated quantities of asbestos. 1.3 Asbestos Survey Results A total of 11 samples were collected in the site buildings during this survey. Suspect materials that were sampled include flooring material and ceiling texture. Roofs were constructed of metal on lathe in the Butler building style. The results of the asbestos survey are summarized in the following paragraphs, and in Table 1, which is attached to this report. The laboratory data sheets are included in Appendix A. Regulated quantities of asbestos were detected in 6 of the 11 samples collected. Asbestos was detected in floor tile, and floor tile bitumen (mastic). Floor tile and floor the mastic are considered to be non -friable materials and can be left in place during demolition in the state of Florida. According to EPA NESHAP regulations, friable material containing less than one percent asbestos as verified by a more accurate Point Count Method is not considered to be a regulated material. Point Count Method is quantitatively more accurate than PLM in determining the percentage of asbestos. Therefore, pursuant to the NESHAP regulations, the three floor file samples taken from Velocity (exhibiting an asbestos content of less than one percent by PLM) were submitted for supplemental analysis using the Point Count Method. The results of the Point Count analysis confirmed that asbestos concentrations greater than one percent asbestos are present in these samples. 2.0 Lead Based Paint SES conducted a thorough lead-based evaluation to include paint testing during the course of this assessment. Areas selected for testing included each area that would potentially form a portion of the demolition waste stream, as well as those areas selected to represent "living space" as defined utilizing Housing and Urban Development (HUD) guidelines for testing of lead paint in residential facilities. SES personnel accessed all areas of each facility building, to include shop areas and office areas to conduct lead- based paint testing. Random painted surface locations were tested using the LeadCheck Screening method, a direct reading method. Painted surfaces were prepared utilizing the following procedure: (1) dust and dirt were cleaned and removed from the area to be tested; (2) a clean knife penetrated all layers of paint at a diagonal angle to the bare/substrate surface. The following procedure was utilized to activate the LeadCheck b'd T09E-S29(LOb) opue1jo - dnoig ddl a41 ecs:so 20 at daS swabs: (1) squeezing and crushing points marked "A" and "B" located on the swab; (2) shaking and squeezing the swab, with the porous fiber Swab tip facing down, until the yellow liquid (chelating agent) comes to the tip of the Swab (activating the swab for Iead testing); (3) rubbing the swab on an approximate 2"x2" test area for at least 30 seconds. A Swab that turns pink indicates a positive screening result. SES randomly tested paints on interior walls, interior and exterior surfaces of doors and doorframes, and window frames. In addition, we tested painted beams, roofing metal (coated with a material that did not appear to be paint) structural trusses and the entire painted surface of the AST. No indications of the presence of lead-based paint were detected during this assessment. 3.0 AST EVALUATION SES Personnel performed an inspection of the AST located near the J & S building. Our inspection included examination of piping and appurtenances, visual inspection for soil staining, testing of tank for lead-based paint and examination of the tank mounting area. Based on visual observation, no evidence of a leak or seepage was detected. SES personnel examined the area around the dispenser, as well as the area inside the tank pit and the area immediately adjacent to the fill ports for the aircraft. hi addition to the concrete structures, SES personnel examined the exposed soil proximal to the tank. No evidence of ground contamination was observed. SES personnel also checked the seals on each of the piping appurtenances during filling. In order to conduct this test, the tank owner was asked to engage the system and dispense fuel. During fuel dispensing, pressure was placed on time system by sealing the handle with a cloth and hand pressure. No leaks in the seals were observed. Lead-based paint was tested on the tank, and in the tank pit. Leadcheck swabs were used on each of the painted surfaces. No indication that lead is present was observed with the swabs. 4 S'd 509E-SSBtL04] opue5a0 - dnoi0 ydl a41 e0S:60 20 Bt des Based on visual observation and lead based paint testing, no ground contamination, lead- based paint, or leakage appeared to be associated with the AST. 4.0 CONCLUSIONS AND RECOMMENDATIONS Regulated quantities of asbestos were detected in six samples of black 9 -inch by 9 -inch floor the and associated bitumen (mastic) collected in the entrance to J &;, S. In addition, the floor tile under the carpet in the offices of Velocity contain asbestos. The floor tile is considered to be a non -friable material. SES makes no recommendation for further evaluation or review. SES appreciates the opportunity to present this report to the LPA Group, Inc.
