7008.4100 CONDITIONALLY INSIGNIFICANT VOC USAGE.

Subpart 1.

Applicability.

This part applies to any stationary source claiming VOC usage as a conditionally insignificant activity.

Subp. 2.

VOC usage limit.

The stationary source must limit its use of VOC to less than 200 gallons or 2,000 pounds in each calendar year period calculated according to the method in subpart 4. All VOC usage from all emissions units at the stationary source must be accounted for in the calculated annual usage. This limit applies regardless of the hazardous air pollutant content of the VOC.

Subp. 3.

Record keeping.

The owner or operator claiming VOC usage as a conditionally insignificant activity shall:

A.

maintain records for each calendar year of the number of gallons of VOC-containing materials purchased or used and the maximum VOC content of each material;

B.

maintain a record of the material safety data sheet (MSDS), or a signed statement from the supplier stating the maximum VOC content, for each material;

C.

if the owner or operator ships VOCs off-site for recycling, keep records of the amount of material shipped off-site for recycling and the calculations done to determine the amount to subtract. Acceptable records include: the material safety data sheets, invoices, shipping papers, and/or hazardous waste manifests; and

D.

if requested by the commissioner, calculate and record for any of the previous five calendar years the sum of the actual number of gallons of VOC purchased or used, the calculation itself, and a list of the associated emissions units in which it was used.

Subp. 4.

Calculating VOC usage.

An owner or operator claiming VOC usage as a conditionally insignificant activity must calculate VOC usage using one of the methods in item A or B. If the owner or operator ships spent VOC off-site for recycling, the amount recycled may be subtracted from the amount of VOC used. "Recycling" means the reclamation or reuse, as defined in part 7045.0020, of a VOC. If the owner or operator ships VOC off-site for recycling, the owner or operator shall keep records of the amount of material shipped off-site for recycling and the calculations done to determine the amount to subtract.

A.

Gallons of VOC: gallons of VOC used per calendar year equals volume percentage of VOC multiplied by the gallons of VOC-containing material purchased or used in a calendar year.

B.

Pounds of VOC: pounds of VOC used per calendar year equals gallons purchased or used in a calendar year multiplied by the pounds VOC per gallon; or pounds purchased or used in a calendar year multiplied by weight percent of VOC.
