## Abstract

The EPA issued a final rule on August 10, 2000, that revised the monitoring requirements in Performance Specification 1 (PS-1). The revisions updated requirements for source owners and operators who must install and use continuous stack or duct opacity monitoring equipment. The revisions also updated design and performance validation requirements for continuous opacity monitoring system (COMS) equipment in PS-1. In addition to changes to PS-1, the final rule established differences between gaseous continuous emissions monitoring systems (CEMS) and COMS. The final rule contained a minor error in wording. This action is intended to correct this error. All other preamble and regulatory text printed in the August 10, 2000, final rule is correct.
