Does USC calculate NOx and SO2 emissions
on a monthly basis, and a twelve-month rolling
sum for total NOx and SO2 emissions?
Does the twelve-month rolling sum remain
below NOx emissions of less than 46 tons and
SO2 emissions of less than 40 tons, combined
total?
Is fuel oil sulfur content less than or equal to
0.5 percent by weight for each boiler?
Has natural gas supplier certification been
obtained for the natural gas and stored on site?
Has fuel oil supplier certification been obtained
for each batch of oil received and stored on
site?
Are records of natural gas and fuel oil
consumption, and natural gas and fuel oil
certification shall be maintained on site for a
period of at least five (5) years from the date
generated and made available upon request?
Are Semi-Annual reports including natural gas
and fuel oil certifications, natural gas and fuel
oil consumptions and all recorded parameters
and calculated values submitted to the Manager
of the Technical Management Section, Bureau
of Air Quality postmarked no later than 30
calendar days after the end of the reporting
period?
Does a representative of USC perform a visual
inspection on a semi-annual basis while
burning natural gas and on a daily basis while
burning No. 2 fuel oil?
Do visual inspections include the observation
of opacity during daylight hours where the
inspector records whether the emissions are
clear?
Is the observer trained and knowledgeable
about the effects on visibility of emissions
caused by background contrast, ambient
lighting, observer position relative to lighting,
wind, and the presence of uncombined water?
Are logs kept to record all visual inspections,
including cause and corrective action taken for
any abnormal emissions, maintained for a
period of five (5) years and made available
upon request?
