Title 83 - PUBLIC UTILITIES
Part 535 - BACKGROUND CHECKS AND MERCURY COMPLIANCE
Section 535.230 - Mercury Vapor Air Sample Test Result in Excess of Allowed Levels

a) For each confirmed mercury vapor air sample test result in excess of the levels set forth in Section 535.200(c), a public utility shall immediately notify all State and federal authorities with jurisdiction of its findings and implement the appropriate mercury contamination clean-up procedure with those authorities, to the extent such notification and clean-up is required under pertinent environmental laws or pertinent safety laws and to the extent that the utility has not previously developed protocols for notification and cleanup with State or federal authorities. Notifying all State and federal authorities with jurisdiction is not required should a public utility's existing protocol with those authorities not require it.

b) If a public utility is required, as discussed under subsection (a), to conduct a clean-up, the public utility shall maintain a file of all correspondence regarding each location where it obtained a confirmed mercury vapor air sample test result in excess of the limits set forth in Section 535.200(c) for a period of five years after it receives confirmation from the appropriate State or federal authorities that its mercury clean-up activities are completed and no further work in this regard is needed.
