LEAD-BASED PAINT SAMPLING METHODOLOGY

This survey was conducted using a portable Olympus X-Ray Fluorescence Analyzer (XRF) to determine the levels of lead present in painted surfaces. The objective of this lead survey was to determine, as accurately as possible, the nature and extent of all paint which may be lead-containing.

Paints were grouped by the "Room Equivalent" (room number / function, etc.), "Building Component" (wall, door, window frame, etc.), "Substrate" (plaster, metal, wood, brick, etc.), and "Paint Color". This survey was conducted by Eric Eitzen, an EPA Certified Lead Inspector and a Texas Department of State Health Services (DSHS) Certified Lead Inspector (Certification # 2060568), who was assisted by Jennifer Mc Millin, an Industrial Hygiene Technician. Micro Air of Texas, Inc. is licensed by the DSHS as a Lead Firm in the state of Texas (TDSHS license #2110550).

The Department of Housing and Urban Development (HUD) testing protocol was not used for this inspection, as this facility is not considered to be included in the definition of "Target Housing" or "Child-Occupied Facility"; therefore, not every painted surface of every Room Equivalent was tested. A total of 246 XRF readings were collected at this facility during this inspection.

LIMITATIONS

Micro Air's scope of services was limited primarily to accessible interior and exterior building materials. Destructive sampling (partial or full demolition of wall cavities, plaster ceilings, etc.) was not part of the Scope of Work for this project. While Micro Air made every effort to perform a thorough (comprehensive) survey, the possibility exists that materials containing asbestos were not identified, inaccessible (i.e., pipes located in walls, chases, or above plaster ceilings), or different from those identified at other locations. If additional types of suspect building materials are found at a later date, they must be assumed to contain asbestos until sampled and shown otherwise. The findings and opinions presented are indicative of conditions on the date of our site inspection and should not be relied upon to represent conditions at substantially later dates, due to possible changes in the condition of building materials, renovations, and repairs.

The asbestos and lead-based paint surveys performed at this facility were not designed to determine exact quantities or limits of asbestos-containing materials (ACM) or lead-based paint (LBP), nor to develop removal cost estimates. This survey report is limited primarily to those building materials located inside and outside Building 615 that were accessible at the time of this survey. If additional areas of the building are added to the scope of work for this project that were not included in the original scope of work that Micro Air surveyed, the additional areas would need to be inspected for both asbestos and lead paint prior to any renovation / demolition occurring. This report is for the exclusive use of the client and its agents; any use by unauthorized parties in whole or in part, except as directed by legal jurisdiction, is at the sole risk of the user.
