Narrative Summary of New Rule or Rule Changes: New Rule Amended Rule

The amendments provide a more flexible limit for CO em issions; establishing a higher short-term level (6,000

ppm averaged over 15 minutes), and a lower long-term le vel (1,900 ppm averaged over 8 hours) than the current

rule of 2,000 ppm (averaged over 15 minutes). Overall t he net emssions of CO are expected to be the same or

lower.

Pollutant(s) Regulated by the Rule (Check): ROG (NOx) SO2

(CO) PM TAC (name):
