What is a Turn Around Document?
14
What is a Turn Around Document?

• DEQ Form 100-730
• Why is it called that?
• Dont turn last Years Data around and send that
  back to us!

15
What data will be pre-loaded for 2005?

• Where we have an inventory that was reported for
  a previous year
• All point and process data will be present
• - Where the point was Active or Idle in 2004
• If there were zero emissions of a particular
  pollutant in 2004, this record will not be
  present in 2005.
• Rates and emission amounts will be pre-set to
  zero

37
Material Information
38

• (express as a decimal)
• MMBTU The heat content of a fuel in
• million BTU's per unit of
• material burned

41
Process Rates

• A measurable parameter that relates directly or
  indirectly to air emissions
• Hourly MAXIMUM rate that a process
• unit can operated for an hour
• Daily AVERAGE daily rate
• Annual ACTUAL annual throughput

43
Capacities
44
Capacities

• Design Capacity
• Report for boilers and turbines only
• Capacity in MMBTUs of process equipment
  operating at 100 of a designated rate
• Maximum Nameplate Capacity

  only
• Expressed in megawatts (MW)

  pollutants (HAPs)
• Identify the MACT category

• MACT code tables are available at
  www.deq.state.ok.us/AQDnew/emissions

47
Temporal Data
48
Temporal Data

• Start time

  emission process operated

49
Emissions Information
50
Report Emissions ofRegulated Pollutants Only

• (1) Criteria Pollutants
• CO
• NOx
• SOx
• PM2.5
• PM10 Particulate Matter between
• 10 microns and gt 2.5 microns
• VOCs (ozone precursors)
• Ozone
• Lead

51
Report Emissions ofRegulated Pollutants Only

• (2) Hazardous Air Pollutants (HAPs)
• 187 compounds and compound groups
• e.g.
• Benzene
• Cobalt Cobalt Compounds
• (3) State Toxics
• 21 compounds and compound groups
• - all except Ammonia are HAPs

52
Report Emissions ofRegulated Pollutants Only

• (4) Other Federal Regulated Pollutants
• Dioxins/Furans
• Fluorides
• Certain metals in the elemental form must be
• reported separately, e.g.
• Beryllium
• Cadmium
• Mercury
• (5) Other State Regulated Pollutants
• H2SO4
• 4 Total Reduced Sulfur Compounds

53
Report Emissions ofRegulated Pollutants Only

• What about a non-regulated pollutant where there
  is an emission limit in our permit?
• Report under the relevant broader category where
  applicable
• e.g., VOC non-HAP
• Do not report if there is no applicable regulated
  pollutant or pollutant group
• e.g., TSP (Total Suspended Particulate matter)

54
Avoid Double-counting!

• Is the emission
• 1. A Hazardous Air Pollutant (HAP) or other
  federally regulated pollutant?
• 2. Ammonia (NH3)?
• 3. A Totally Reduced Sulfur compound?
• 4. Sulfuric acid?
• 5. A criteria pollutant or a VOC (non-HAP)?
• Once your emission falls into one of these
  categories report it and stop there!

55
Examples

• Methylcyclohexane
• The emission is not a HAP, but it is a VOC
• The answers to Questions 1 4 are No
• The emission would be reported as part of the
• total VOCs (non-Hap) from that process
• Methylanthracene
• The emission is a HAP
• It should be reported specifically as
  methylanthracene, not as a VOC
• Only Question 1 had to be asked

56
Watch Out!

• Some of your pollutants from last year may have
  disappeared
• A paint booth with no HAP emissions and where all
  VOCs had previously all been speciated
  (separated) out will suddenly have no
  pollutants
• In this case, only VOC (non-HAP) emissions need
  to be reported from this point
• You would now need to add a new pollutant -
  VOC (non-HAP)

57
Emissions Amounts
58
Emissions Amounts

• Allowed (tons/year)
• If applicable, enter the Permit or other such
  emission limit for the pollutant
• If there is a permit limit for the point, enter
  the same number for each process
• If no Permit limit, enter 0 (zero)

59
Emissions Amounts

• Excess (tons/year)
• Reported emissions not attributable to normal
  operation, e.g.
• startups, shutdowns, malfunctions, upsets, etc.
• Not necessarily
• (Actual Annual Amount Allowed Annual Amount)
• - short duration events must be included
• Must correspond with Excess Emissions Reports

60
Emissions Amounts

• Amount (tons/year)
• Actual annual emissions of the pollutant
• Must include excess emissions
• Make sure you convert from lbs or grams to tons!

61
Emissions Calculation Method
62
Emissions Calculation Method

• Enter the Approved Method used for determining
  emissions
• See Table One in the Emissions Inventory
  instructions or OAC 252100-5
• Can I use the results from a Portable Emissions
  Analyzer?
• NO!!!

63
Emission Factor Information
64
Emission Factor Information

• What is an Emission Factor?
• A means of relating a measurable parameter (the
  throughput) to the amount of air emissions of a
  particular pollutant from a particular process

65
Emission Factor Information

• Example for CO from X process,
• the emission factor is 20 lbs/MMCF
• Throughput x Emission Factor Emission Amt
• 100 MMCF x 20 lbs 2000 lbs
• MMCF 1 ton CO

66
Emission Factor Information

• (Emission) Factor
• Numeric value
• Dependent upon the process and the pollutant
• From AP-42, webFIRE, Permit Factors
  (manufacturers guarantees)
• If no single emission factor is used (e.g.,
  TANKS, GlyCalc) leave as zero.

67
Emission Factor Information

• (Emission Factor Denominator) Units
• Assumed that the Emission Factor Numerator units
  are lbs or grams
• Should relate to the Throughput Units
• If no single emission factor is used
• (e.g., TANKS, GlyCalc) leave blank
• or no units assigned

68
Control Equipment
69
Control Equipment If Applicable

• Primary Secondary Controls
• Type of equipment used to reduce emissions
• Efficiency
• How much are the emissions reduced by?
• Report as a decimal
• Ensure control efficiencies are included in
• reported actual emission amounts
