Sampling, Analysis, and Assessment

The assessment procedure set out in the rule requires the inspector to classify ACBM, whether confirmed or assumed to be ACM, after each inspection and reinspection, into the broad categories set out in the rule and to explain the basis of each such assessment. The seven categories are damaged or 

The rule had allowed LEAs to use laboratories that received interim accreditation for polarized light microscopy (PLM) analysis under the EPA Interim Asbestos Bulk Sample Analysis Quality Assurance Program until the National Bureau of Standards (NBS) PLM Program became operational and laboratories accredited through that program were available. 40 C.F.R. 763.87(a). 

The inspector must also use this same procedure with respect to any ACBM identified in prior inspections that were the basis for qualifying for the exclusions noted in 40. C.F.R. 5 763.99 and 40 C.F.R. 5 763.88(a)(1). 

Significantly damaged friable surfacing ACM means damaged friable surfacing ACM in a functional space where the damage is extensive and severe. Id.

A major use of ELISA is to obtain data from sample analysis and assess whether a particular sample is positive (contains a particular analyte) or negative (does not contain analyte). This requires both the examination of the specific assay parameters (assessing sensitivity and specificity) and the defining of a specific population in terms of data obtained and with reference to other data from other tests. The establishment of a population statistic requires that the data be obtained and analyzed. The analysis determines the type of distribution of data, and hence any sample value can be assessed with reference to all data in that population. The amount of data obtained to establish a population affects the certainty of any result, as does where the samples were taken from to establish the population (sampling/survey statistics).
