OSHA's regulations for lead in construction do not give minimum concentrations of lead, only the presence of lead invokes the regulations. KTA has performed these tests only to ascertain the presence of hazardous metals in the existing coating. Values shown as "less than" (e.g. < 77.1 ppm) indicate that the sample concentration was less than the detection limit of the analytical method, The detection limit is affected by sample size, dilution, method and equipment and can vary from sample to sample. Laboratory standard organizations require that results obtained that are less than the method detection limit be reported as "less than" or "non- detectable." The OSHA Lead in Construction Standard requires that controls be implemented if any detectable concentrations of lead are present. The OSHA Compliance Directive issued regarding the OSHA Lead in Construction Standard, Instruction CPL 2-2.58, states that if an employer has appropriately tested for lead (e.g. tested all layers of paints or coatings that may be disturbed) utilizing a valid detection method for the presence of lead and found no detectable levels of lead, the standard does not apply. This allows NYSOGS to confidently treat results reported as "less than" as non-lead containing. Results reported with detectable concentrations of lead and other toxic metals would require the contractor performing the work to implement interim controls and assess actual employee exposures in accordance with the OSHA Lead in Construction or other applicable standards. The requirements of the OSHA Lead in Construction Standard, 29 CFR 1926.62 are invoked, if any detectable quantities of lead are present in a sample. Please note that the OSHA Lead in Construction Standard would be invoked only when construction activities involve mechanical disturbance of the paint. These activities include but are limited to abrasive blast cleaning, scraping, burning, and grinding. There is a similar Elevated Water Storage Tank City of Arden Hills South Tank 18
