[40 CFR 60.482-11a(b)(3)(ii)]

 

v.  If less than 0.25% of the connectors in the process unit were leaking during the previous monitoring, the permittee must monitor at least 50% of the connectors within 4 years of the start of the monitoring period. If 0.35% or more of the connectors monitored during the 4-year period are found to leak, the permittee must monitor all connectors that have not yet been monitored as soon as practical, but within the next 6 months. At the conclusion of the monitoring, a new monitoring period shall be started pursuant to Condition 2.3.h, based on the percent of leaking connectors. If less than 0.35% of the connectors monitored during the 4-year period are found to leak, the permittee must monitor all connectors that have not yet been monitored within 8-years of the start of the monitoring period. [40 CFR 60.482-11a(b)(3)(iii)]

ix.  Any connector that is designated unsafe to monitor is exempt from the requirements of this Condition if the permittee demonstrates that the connector is unsafe to monitor because monitoring personnel would be exposed to an immediate danger as a consequence of monitoring, and the permittee has a written plan that requires monitoring of the connector as frequently as practicable during safe to monitor times, but not more frequently than the periodic monitoring schedule otherwise applicable, and repair of the connector as required in this condition. [40 CFR 60.482-11a(e)]

 

 

x.  Any connector that is inaccessible or is ceramic or ceramic lined is exempt from the monitoring, leak repair, recordkeeping and reporting requirements of this condition. However, if any inaccessible, ceramic, or ceramic lined connector is observed by visual, audible, olfactory, or other means to be leaking, the indications of leak shall be eliminated as soon as practicable. [40 CFR 60.482-11a(f)]

4.0  COMPLIANCE DEMONSTRATION

 

4.1.  Testing Requirements

By no later than 18 months after startup, the permittee must conduct a source test of the CO2 vent to verify emission factors used to determine compliance with the PSEL in Condition 3.1.

 

a.  Non-water soluble VOC emissions must be measured using EPA Method 18;

 

b.  Water soluble VOC emissions must be measured by an approved isokinetic method (i.e. aldehydes with SW-846 Method 0010);

 

c.  EPA Methods 1-4 must be used for gas flowrate measurements;

 

d.  The process operating parameters (syrup feed rate, ethanol production rate, etc.) must be monitored and recorded during the source test.

 

e.  All tests must be conducted in accordance with the Department’s Source Sampling Manual and the approved pretest plan. The pretest plan must be submitted at least 15 days in advance and approved by the Regional Source Test Coordinator. Test data and results must be submitted for review to the Regional Source Test Coordinator within 30 days unless otherwise approved in the pretest plan.

 

f.  Only regular operating staff may adjust the combustion system or production processes and emission control parameters during the source test and within two hours prior to the source test. Any operating adjustments made during the source test, which are a result of consultation with source testing personnel, equipment vendors or consultants, may render the source test invalid.

4.2.  PSEL Compliance Monitoring

Compliance with the PSEL is determined for each 12-consecutive calendar month period based on the following calculation for each pollutant:

E  =  S(EF x P) + AI/2000 lbs

Where,

E  =  pollutant emissions (ton/yr);

EF  =  pollutant emission factor (see condition 10.0);

P  =  process production (see condition 11.0)

AI  =  Aggregate Insignificant Emissions (1.0 ton/yr)

4.3.  Emission Factors

The permittee must use the default emission factors provided in condition 10.0 for calculating pollutant emissions, unless alternative emission factors are approved by the Department. The permittee may request or the Department may require using alternative emission factors provided they are based on actual test data or other documentation (e.g., AP-42 compilation of emission factors) that has been reviewed and approved by the Department.

4.4.  Tank Emissions

The permittee must use the most recent version of EPA TANKs or equivalent AP-42 algorithm to calculate monthly emissions from the Combined Hydrolyzate Tank (T1040, Emission Point #4), Dilute Acetic Acid Day Tank (T4010, Emission Point #16) and Gasoline Storage Tank (T9960, Emission Point #27). The permittee must use the most recent version of EPA WATER9 or other appropriate method to calculate monthly emissions from the Wastewater Treatment Facility (X9510, Emission Point #26).

4.5.  Equipment Leak Fugitives

The permittee must use the procedures outlined in EPA’s Protocol for Equipment Emissions Estimates, Synthetic Organic Manufacturing Industry (SOCMI) – EPA document 453/R-95-017. If the Average Emission Factor Approach is used to estimate equipment leak emissions then the following equation and assumptions shall be used to calculate equipment leak fugitives:

 

EVOC  =  (FA * WFVOC * N) * (1 – CEF)

 

Where,
