The definitions applicable to this rule are contained in paragraphs (A), (B), and (D) of rule 3745-21-01 of the Administrative Code.
No owner or operator of facility subject to this rule may cause, allow or permit the discharge into the ambient air of any VOC in excess of the following limitations:
[Comment: This is an alternative emission limitation in place of the emission limitations separately applicable to primer-surfacer coating operations and topcoat coating operations at the facility.]
Any owner or operator of coating operations for which emission limitations are specified under paragraph (C) of this rule shall do the following:
[Comment: If a facility subject to this rule already has a work practice plan in place under the national emission standards for hazardous air pollutants (NESHAP), the facility can add to its NESHAP work practice plan the practices and procedures for minimizing non-HAP VOC emissions].
The VOC content of a reactive adhesive shall be determined from coating formulation data from the coating user or coating manufacturer, or by the analytical procedures of 40 CFR part 63, subpart PPPP, appendix A. In the event of a dispute between coating formulation data and data obtained by analytical procedures, the data obtained by analytical procedures shall be employed, except as otherwise provided in paragraph (B)(12) of rule 3745-21-10 of the Administrative Code.
The as-applied VOC content of a coating applied by a dip coater shall be determined by the owner or operator as a rolling thirty-day average of the VOC content of the material (coating and thinner) added to the reservoir of the dip coater. The rolling thirty-day average VOC content (C30), expressed in pounds of VOC per gallon of coating, excluding water and exempt solvents, as applied, shall be calculated for each day of operation of the dip coater as follows:
Where:
Ai,30 = amount of material i added to the reservoir of the dip coater during a thirty-day period consisting of the day of operation of the dip coater plus the previous twenty-nine calendar days, expressed in gallons
Ci,VOC = VOC content of material i expressed in pounds of VOC per gallon.
Vi,solids = volume fraction of solids (nonvolatile matter) in material i.
Vi,VOC = volume fraction of VOC in material i.
i = subscript denoting a specific material (coating or thinner) added to the reservoir of the dip coater during the thirty-day period.
n = total number of materials (coatings and thinners) added to the reservoir of the dip coater during the thirty-day period.
The as applied VOC content of an EDP primer shall be determined by the owner or operator as a monthly average of the VOC content of the material (coating and thinner) added to the reservoir of the dip coater during a calendar month. The monthly average VOC content (Cmonth), expressed in pounds of VOC per gallon of solids, as applied, shall be calculated for each month of operation of the dip coater as follows:
Where:
Ai month = amount of material i added to the reservoir of the dip coater during a calendar month, expressed in gallons.
Ci,VOC = VOC content of material i expressed in pounds of VOC per gallon.
Vi,solids = volume fraction of solids (nonvolatile matter) in material i.
i = subscript denoting a specific material (coating or thinner) added to the reservoir of the dip coater during the calendar month.
n = total number of materials (coatings and thinners) added to the reservoir of the dip coater during the calendar month.
RT = LS/LE
Where:
LS = total volume of coating solids that is added to the EDP coating operation in a calendar month (gallons).
LE = total volume design capacity of the EDP system, which is the total liquid volume contained in the EDP system's tanks, pumps, recirculating lines, filters, etc. at the system's designed liquid operating level (gallons).
For add-on air pollution control equipment employed in accordance with paragraph (D) of this rule, the owner or operator shall do the following:
RT = Vs / VE, truncated after three decimal places
Where:
VE = volume of EDP primer coating tank, in gallons.
Vs = volume of solids added to the EDP primer coating tank during the month, in gallons.
Vs = summation of (Ai,month)(Vi,solids) for i=1 to i=n
Ai,month= amount of material i added to the reservoir of the dip coater during a calendar month, expressed in gallons.
Vi,solids= volume fraction of solids (nonvolatile matter) in material i.
i = subscript denoting a specific material (coating or thinner) added to the reservoir of the dip coater during the calendar month.
n = total number of materials (coatings and thinners) added to the reservoir of the dip coater during the calendar month.
Then calculate or select the appropriate limit according to paragraph (C) (1)(a) of this rule.
For the coating-related activities and cleaning materials, the owner or operator shall maintain the following records on a monthly basis:
For an add-on pollution control system that is employed in accordance with paragraph (D) of this rule, the owner or operator shall maintain the same monitoring records as specified under paragraph (K)(5) of rule 3745-21-15 of the Administrative Code.
Provided total VOC emissions are less than 15.0 pounds per day, the owner or operator may elect to maintain the following records in lieu of the records required under paragraph (J)(1)(a) of this rule:
