(A) A daily average operating opacity of 10 percent on more than two days within any 12-month period, with the days separated from each other by at least 30 days, and with opacity determined by EPA Method 9; or

(B) A maximum opacity of 20 percent as measured by EPA Method 9 at any time.

(A) A daily average operating opacity of 10 percent on more than two days within any 12-month period that are separated from each other by at least 30 days, as determined by EPA Method 9; or
