Methods for Measurement of Visible Emissions
This action finalizes Methods 203A, 203B, and 203C for determining visible emissions using data reduction procedures that are more appropriate for State Implementation Plan (SIP) rules than Method 9, the method currently used. This action was requested by the States and is needed for the special data reduction requirements in their rules. The intended effect is to provide States with an expanded array of data reduction procedures for determining compliance with their SIP opacity regulations. In addition, this action amends various testing provisions in the New Source Performance Standards (NSPS) to correct inadvertent errors and amend a testing provision.
