Title V 0 YES ■ NO Initial Review/Data Entry ■ Enter date received into ED. Date Received: 5/26/20 Assigned to appropriate individual. Date Assigned: 5/26/20 Date Due: 6/26/20 Paper copy submitted: One copy received with supporting documentation,certification form signed by responsible official,and appears generally complete; OR Electronic copy submitted: All supporting documentation and certification form(with time/date stamp)signed by responsible official has been received. 05/18/20 Comments: Inventory Review ■ All forms and supporting documentation appear to be complete if paper submission(check ED OS data if electronic). Contact,address,phone number changes entered into I-Beam/Facilities if necessary. All known operating scenarios,control devices,and emission release points have been entered for each emission source(pennitted, insignificant,and unpermitted)or note that the emission source was not operated or not required to report. Check if SCC codes for each OS are accurate and update if needed. Evaluate"U"sources for significance and address according to policy. Calculations/forms appear to add up correctly. All compliance issues are being addressed(e.g.Toxics limits,above TV thresholds, large emissions increase/decrease, installation ■ without a permit). ■ All volatile HAPs/TAPS were included in the VOC total. Calculations and control efficiencies appear correct. Emission factors are the best available and most current factors appropriate for the reporting facility(e.g. stack testing,AP-42,etc.). Review facility comments and address any issues. Update ED(Data Entry Main)if additional information is required(corrections due date and date received). Check all ED QA/QC reports. Comparison with previous emission inventory must be made and outliers(> 10%)must be investigated and explained. Put inventory review comments and summarize any changes in ED-Data Entry Main"DAQ internal comments". Print and attach the facility total report.
