Lead concentrations should be reported in micrograms per gram (micrograms/gm); or(3) an alternate method approved in advance by the executive director or a designated representative of the Texas Air Control Board (TACB).(b) Results of the test(s) required in subsection (a) of this section must be available to the TACB staff or staff from governmental entities having jurisdiction at the site for the duration of the abrasive blasting project. The results must include the name of the testing facility and a person responsible for the accuracy of the test results.(c) Successive coatings need not be retested following initial testing, provided the owner or operator of the water storage tank can furnish verifiable documentation that the lead level of the post-testing coatings is less than 1.0% (10,000 micrograms/gm) lead by weight.30 Tex.
