  1. ACTIVITY LEVEL (AL) is the amount of operating hours or quantity of material used, processed, produced, or combusted during the Investment Period which is expressed in a manner consistent with the units of the Requested Emission Limitation and Allowable Rule Emission Limitation. For purposes of this definition, the value Qr shall be the Activity Level for any Source using a coating which is subject to a Regulation XI VOC emission limitation.
  2. ALLOWABLE RULE EMISSION LIMITATION (ERa) represents the most stringent Emission Limitation (in pounds per unit of activity level) of an applicable Selected Regulation IV or Regulation XI rule which is in effect on the starting date of the AQIP Plan Registration.

  6. INVESTMENT PERIOD means the time period that an Investor uses AQIP emission reductions as an alternative to compliance with an Allowable Rule Emission Limitation of an applicable Selected Regulation IV or Regulation XI rule pursuant to subdivision (e) of Rule 2501. The Investment Period shall not exceed 12 months.
  7. PERFORMANCE ADJUSTMENT FACTOR (PAF) is a factor specified in the Emissions Quantification Methodology to account for the change (if any) in the performance or efficiency associated with using a material or process at the Allowable Rule Emission Limitation as compared to the Requested Emission Limitation.
  8. PURCHASED AQIP EMISSION REDUCTIONS (AQIPPurchased) are the pounds of VOC, NOx, CO, SOx and PM10 emission reductions purchased by Investors as specified in their approved Plans.
  9. REMAINING AQIP EMISSION REDUCTIONS (AQIPRemaining) means the amount of any excess or unused AQIP emission reductions left over from the original amount purchased.
  10. REQUESTED EMISSION LIMITATION (ERr) means any Emission Limitation used in a Source (in pounds per unit of activity level) which an Investor seeks to use as an alternative to compliance with an Allowable Rule Emission Limitation.
  11. REQUIRED AQIP EMISSION REDUCTIONS (AQIPRequired) are the projected amount of AQIP Emission Reductions needed to offset an increase in emissions, or emissions forgone, at a Source during a specified Investment Period.

  15. VOC-CONTAINING MATERIAL means any coating, solvent, adhesive, or graphic arts material containing VOC.
  16. WASTE ADJUSTMENT means the difference in VOC emissions between the use of VOC-Containing Material(s) at the Requested Emission Limitation as compared with the use of VOC-Containing Materials at the Allowable Rule Emission Limitation which are prevented due to offsite waste shipments, or solvent recycling techniques or processes which recover a portion of the original volume of solvent.

(d)    Emission Quantification Methodology

  1. The following emissions quantification methodologies shall be used to determine the amount of AQIP emission reductions required to satisfy the emission limitations of a Selected Regulation IV rule or Regulation XI rule pursuant to clause (e)(6)(A)(iii) of Rule 2501:

    (A)    The following methodology shall apply to any source, except those sources using a coating which is subject to an Allowable Rule Emission Limitation:
     

    AQIPRequired  =  (ERr x AL) - [ERa x (AL x PAF)] 
         
    Where:     
         
    AQIPRequired  Required AQIP Emission Reductions (pounds) 
    ERr  Requested Emission Limitation (pounds/unit of Activity Level)
     
    AL  Activity Level specified in the AQIP Plan Registration which is projected to occur during the Investment Period 
    ERa  Allowable Rule Emission Limitation (pounds/unit of Activity Level) 
    PAF  Performance Adjustment Factor, if applicable
      (B)    The following methodology shall apply to any Source using a coating which is subject to a Regulation XI VOC emission limitation:
     
    Undisplayed Graphic 
    Where:     
    AQIPRequired  Required AQIP Emission Reductions (pounds) 
    Qr  quantity of material applied, at the Requested Emission Limitation, which is projected to occur during the Investment Period (gallons) 
    VOCr  VOC content at the Requested Emission Limitation (pounds of VOC per gallon of applied coating, less water, less exempt solvent) 
    dr  density of VOC solvent at the Requested Emission Limitation (pounds of VOC per gallon of VOC) 
    CEr  overall percent control efficiency at the Requested Emission Limitation (pounds of VOC reduced in the emission control system per pound of VOC emission generated over uncontrolled conditions); if no emission control system exists, then CEr is zero 
    VOCa  VOC content at the Allowable Rule Emission Limitation (pounds of VOC per gallon of coating, less water, less exempt solvent) 
    da  density of VOC solvent at the Allowable Rule Emission Limitation (pounds of VOC per gallon of VOC)
     
  2. The following methodology shall be used to quantify the amount of AQIP emission reductions remaining in order to comply with the reporting requirements of subdivision (g) of this rule and paragraph (e)(6) of Rule 2501:
    AQIPRemaining  =  AQIPPurchased - AQIPUsed 
    Where:     
    AQIPRemaining  Remaining AQIP Emission Reductions (pounds) 
    AQIPPurchased  Purchased AQIP Emission Reductions (pounds) 
    AQIPUsed  Used AQIP Emission Reductions (pounds)
     

    (A)    As required under clause (e)(6)(A)(iii) of Rule 2501, the value of AQIPPurchased shall be greater than or equal to the amount of AQIPUsed.

    (B)    AQIPUsed shall be determined using the emissions quantification methodologies specified in paragraph (d)(1), except that the quantities of AL and Qr shall be the actual Activity Level and quantity of coating used, rather than the projected quantities.

    (C)    If an Investor prevents VOC emissions due to offsite waste shipments or solvent recycling techniques or processes which recover a portion of the original volume of the VOC-Containing Materials specified in the Plan, the value AQIPUsed as determined pursuant to subparagraph (d)(2)(B) of this rule may, upon Executive Officer approval, be reduced by the quantity of Waste Adjustment. The Executive Officer shall approve the reduction, provided the Investor has submitted the records required by subparagraph (f)(1)(G). If an Investor elects to apply Waste Adjustment, the Investor shall maintain separate waste streams and/or storage containers for each VOC-Containing Material specified in the Plan. Waste streams and/or storage containers which contain a mixture of each VOC-Containing Material specified in the Plan and any additional VOC-Containing Materials shall not be applied towards the Waste Adjustment. The following methodology shall be used to quantify the value of Waste Adjustment:

    Where:     
         
    Waste Adjustment  the amount of VOC emissions as defined in paragraph (c)(16) 
    Q  the quantity of organic liquid waste generated during the Investment Period resulting from the use of VOC-Containing Materials identified in the Plan (gallons of coating or solvent waste, or if applicable, pounds of lithographic ink waste) 
    VOC  VOCr (applicable to a coating), ERr, (applicable to a solvent) or lithographic oil content at the Requested Emission Limitation (pounds of VOC per gallon of material or, if applicable, pounds of lithographic oil per pound of lithographic ink) 
    WAF  waste adjustment factor (percentage of organic liquid waste which may be claimed) 
    RF  the VOC retention factor for lithographic printing operations (0.2 for gas or electric dryer, 0.5 for infrared dryer, 0.9 for no dryer) 
    CEr  overall percent control efficiency at the Requested Emission Limitation (pounds of VOC reduced in the emission control system per pound of VOC emission generated over uncontrolled conditions); if no emission control system exists, then CEr is zero 
    Material %  percent of original VOC-Containing Material in Q measured in terms of volume % for coatings and solvents, and by weight % for lithographic inks 
    R  the ratio of the VOC at the Allowable Rule Emission Limitation to that at the Requested Emission Limitation where the units of VOC are expressed in terms of pounds of VOC per gallon of coating (or ink) less water and less exempt solvent, or pounds of VOC per gallon of material (applicable to a solvent) 
    PAF  Performance Adjustment Factor, if applicable
     

    The value of WAF shall be 1 if the value of Material % is determined by a laboratory analysis. If Material % is determined from the waste profile data on a hazardous waste manifest, then the value of WAF shall be 0.5.
