7.06(l)(c); 

d. Propose the duration and frequency of startup, shutdown, soot blowing and any 

other specified conditions; 

e. Document the need for visible emission limitations greater than 15% opacity 

during startup, shutdown, soot blowing and any other specified operating conditions; 

f. Propose visible emission limitations that the facility will comply with during 

startup, shutdown, soot blowing and other specified operating conditions; 

g. Describe all necessary corrective action procedures and include schedules for 

implementing such procedures; and

3. ' Department Action. 

a Upon completion of review, the Department shall either approve or disapprove 

the plan of good operating practices. 

b. The terms and conditions of an approved plan shall be incorporated into the 

facility's Operating Permit. 

c. A Department approval shall specify the visible emission limitations for each

approval. 

d. Modifications to those portions of an approved plan that are not incorporated into 

the facility's Operating Permit shall be maintained on-site and made available to 

Department representatives upon request. Modifications to an approved plan shall

renewal application. The Department may require modification of an approved plan. 

4. Notice of Exceedances. Any facility operating pursuant to a Department approval 

issued under this exception shall notify the Department of any exceedance of a visible 

emission limitation in the time and manner required by the relevant permit deviation
