SECTION 218.401 FLEXOGRAPHIC AND ROTOGRAVURE PRINTING
Section 218.401 Flexographic and Rotogravure Printing
a) No owner or operator of a subject flexographic, packaging rotogravure or publication rotogravure printing line shall apply at any time any coating or ink unless the VOM content does not exceed the limitation specified in either subsection (a)(1) or (a)(2) below. Compliance with this Section must be demonstrated through the applicable coating or ink analysis test methods and procedures specified in Section 218.105(a) of this Part and the recordkeeping and reporting requirements specified in Section 218.404(c) of this Part. As an alternative to compliance with this subsection, a subject printing line may meet the requirements of subsection (b) or (c) below.
1) Forty percent VOM by volume of the coating and ink (minus water and any compounds which are specifically exempted from the definition of VOM), or
2) Twenty-five percent VOM by volume of the volatile content in the coating and ink.
b) No owner or operator of a subject flexographic, packaging rotogravure or publication rotogravure printing line shall apply coatings or inks on the subject printing line unless the weighted average, by volume, VOM content of all coatings and inks as applied each day on the subject printing line does not exceed the limitation specified in either subsection (a)(1) (as determined by subsection (b)(1)) or subsection (a)(2)) (as determined by subsection (b)(2)). Compliance with this subsection must be demonstrated through the applicable coating or ink analysis test methods and procedures specified in Section 218.105(a) of this Part and the recordkeeping and reporting requirements specified in Section 218.404(d) of this Part.
1) The following equation shall be used to determine if the weighted average VOM content of all coatings and inks as applied each day on the subject printing line exceeds the limitation specified in subsection (a)(1) of this Section.
|
VOM(i)(A) |
= |
n Σ i=1 |
Ci Li (Vsi + VVOMi) |
|
n Σ i=1 |
Li (Vsi + VVOMi) |
where:
|
VOM(i)(A) |
= |
The weighted average VOM content in units of percent VOM by volume of all coatings and inks (minus water and any compounds which are specifically exempted from the definition of VOM) used each day; |
|
i |
= |
Subscript denoting a specific coating or ink as applied; |
|
n |
= |
The number of different coatings and/or inks as applied each day on a printing line; |
|
Ci |
= |
The VOM content in units of percent VOM by volume of each coating or ink as applied (minus water and any compounds which are specifically exempted from the definition of VOM); |
|
Li |
= |
The liquid volume of each coating or ink as applied in units of l (gal); |
|
Vsi |
= |
The volume fraction of solids in each coating or ink as applied and |
|
VVOMi |
= |
The volume fraction of VOM in each coating or ink as applied. |
2) The following equation shall be used to determine if the weighted average VOM content of all coatings and inks as applied each day on the subject printing line exceeds the limitation specified in subsection (a)(2) of this Section.
|
VOM(i)(B) |
= |
n Σ i=1 |
Ci Li VVMi |
|
n Σ i=1 |
Li VVMi |
where:
|
VOM(i)(B) |
= |
The weighted average VOM content in units of percent VOM by volume of the volatile content of all coatings and inks used each day; |
|
i |
= |
Subscript denoting a specific coating or ink as applied; |
|
n |
= |
The number of different coatings and/or inks as applied each day on each printing line; |
|
Ci |
= |
The VOM content in units of percent VOM by volume of the volatile matter in each coating or ink as applied; |
|
Li |
= |
The liquid volume of each coating or ink as applied in units of l (gal) and |
|
VVMi |
= |
The volume fraction of volatile matter in each coating or ink as applied. |
c) No owner or operator of a subject flexographic, packaging rotogravure or publication rotogravure printing line equipped with a capture system and control device shall operate the subject printing line unless the owner or operator meets the requirements in subsection (c)(1), (c)(2), or (c)(3) and subsections (c)(4), (c)(5) and (c)(6) below.
1) A carbon adsorption system is used which reduces the captured VOM emissions by at least 90 percent by weight, or
2) An incineration system is used which reduces the captured VOM emissions by at least 90 percent by weight, or
3) An alternative VOM emission reduction system is used which is demonstrated to have at least a 90 percent control device efficiency, approved by the Agency and approved by USEPA as a SIP revision, and
4) The printing line is equipped with a capture system and control device that provides an overall reduction in VOM emissions of at least:
A) 75 percent where a publication rotogravure printing line is employed, or
B) 65 percent where a packaging rotogravure printing line is employed, or
C) 60 percent where a flexographic printing line is employed, and
5) The control device is equipped with the applicable monitoring equipment specified in Section 218.105(d)(2) of this Part and except as provided in Section 218.105(d)(3) of this Part, the monitoring equipment is installed, calibrated, operated and maintained according to vendor specifications at all times the control device is in use, and
6) The capture system and control device are operated at all times when the subject printing line is in operation. The owner or operator shall demonstrate compliance with this subsection by using the applicable capture system and control device test methods and procedures specified in Section 218.105(c) through Section 218.105(f) of this Part and by complying with the recordkeeping and reporting requirements specified in Section 218.404(e) of this Part.
