*The discharge of mercury above the quantification level shall
represent an exceedence of the local limit. Mercury sampling procedures,
preservation and handling, and analytical protocol for compliance
monitoring shall be in accordance with the USEPA Method 245.1, unless
Method 1631 is required by the City. The quantification level shall
be 0.2 ug/l for Method 245.1 or 0.5 ng/l for Method 1631, unless higher
levels are appropriate due to sample matrix interference.
