INSTRUCTIONS FOR EUD-2

EMISSIONS UNIT DESCRIPTION FOR VOC EMITTING SOURCES

Use this form to describe emissions units that use, process, store or produce substances containing VOC and that primarily emit VOC, such as painting or coating operations and printers.

In addition, this form may also be useful for certain HAP emitting sources. The purpose of this form is to help you collect and organize technical data, including operational characteristics, applicable requirements, compliance terms, and emissions.

Section A - The emissions unit ID should be consistent with the one used in section I of form GIS. Enter the four-digit SIC code for the unit, which may be different from that used to describe the facility as a whole. In addition, enter the Source Classification Code (SCC), if known or available, but this is not mandatory.

Section B - There may be other information that the permitting authority will need to know that is not specifically requested on the forms and that should be included on attachments. Such information would include information needed to adequately identify the emissions unit and to determine its applicable requirements.

Section C - Identify and describe any associated air pollution control device for the unit described above. If data (such as control efficiency) provided by the vendor, attach documentation (if available); If other basis, indicate how determined (e.g., AP-42).

Section D - Complete this section only if ambient impact assessment is an applicable requirement or the facility is a temporary source. This is not common.

Section E - VOC content and usage values are typically used to calculate emissions. Actual usage will be multiplied by VOC content to calculate actual emissions, while maximum usage will be multiplied by VOC content to calculate PTE. Explain the basis for the usage and VOC content values on an attachment (e.g., material safety data sheet or MSDS). Also, EPA Reference Method 24 of 40 CFR Part 60, Appendix A, can also be used to determine VOC content but this is not required solely for these application purposes. When VOC Content is determined through testing or calculation by the applicant, the applicant must attach test data and calculations.

Paperwork Reduction Act Burden Statement: This collection of information is approved by OMB under the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. (OMB Control No. 2060-0036). Responses to this collection of information are mandatory (40 CFR 71). An agency may not conduct or sponsor, and a person is not required to respond to, a collection of information unless it displays a currently valid OMB control number. The public reporting and recordkeeping burden for this collection of information is estimated to 268 hours per response. Send comments on the Agency’s need for this information, the accuracy of the provided burden estimates and any suggested methods for minimizing respondent burden to the Regulatory Support Division Director, U.S. Environmental Protection Agency (2821T), 1200 Pennsylvania Ave., NW, Washington, D.C. 20460. Include the OMB control number in any correspondence.
