1. fully enclose the item, or surround the structure, to be blasted; or

2. prepare and implement a best management practices (BMP) plan as described in LAC 33:III.1331.

B. Blast cabinet exhaust shall be re-circulated to the cabinet or vented to emission control equipment.

C. If tarps are used to confine emissions due to abrasive blasting, the tarps shall:

1. have overlapping seams to prevent leakage of particulate matter;

2. have a shade factor of 80 percent or greater; and

3. be repaired prior to use if any single tear greater than 1 foot in length is present or if tears greater than 6 inches in length each are present.

D. If blasting is performed in a permanent building with a particulate matter collection system, the collection system shall be exhausted through effective control equipment with a particulate matter outlet grain loading of 0.05 gr/dscf or less, as documented by the control equipment manufacturer or demonstrated by performance testing.

E. When abrasive blasting is performed over waters of the state, blasting material or visible floating solids shall be prevented from reaching waters of the state or minimized to the maximum extent possible as specified in the facility and/or activity BMP or in accordance with the LPDES permit program.

F. Abrasive blasting activities shall not create a nuisance.

G. The facility shall maintain stockpiles of new and/or spent abrasive material in a manner that will minimize fugitive airborne emissions. Measures to minimize emissions shall include, but not be limited to, the following:

1. covering stockpiled material;

2. wetting stockpiled material; or

3. keeping stockpiled material in containers.

H. All emission control equipment shall be used and diligently maintained in proper working order according to the manufacturer's specifications whenever any emissions are being generated that can be controlled by the facility, even if the ambient air quality standards in affected areas are not exceeded.
