3 Course Overview Background and Control of MFHAPs Requirements Equipment Management Practices Exemptions Compliance Notification, Recordkeeping & Reporting Q & A - Contact Information

4 Background: Why Did EPA Create This Regulation? The Clean Air Act (CAA) required EPA to develop air emission standards for a list of 187 hazardous air pollutants (HAPs) The standards are to reduce exposure to HAPs because the chemicals are known, or suspected, to cause cancer or other serious health effects, such as birth defects

5 Metal Finishing Hazardous Air Pollutants MFHAPs - materials that contain: CadmiumChromium LeadNickel in amounts greater than or equal to 0.1 percent by weight (as the metal), and Manganese in amounts greater than or equal to 1.0 percent by weight

9 Dry Abrasive Blasting Activity Al l equipment and activities necessary to perform dry abrasive blasting operations which use materials that contain MFHAP or that have the potential to emit MFHAP

10 Dry Abrasive Blasting Requirements Dry Abrasive Blasting for glove box type operation must have enclosed & unvented blast chamber Management & P2 Practices: Minimize dust generation during emptying of the enclosure; and Operate all equipment used in the blasting operation according to manufacturers instructions.

11 Dry Abrasive Blasting Requirements Vented enclosure: Must use a control system with a capture device, and a cartridge, fabric, or HEPA filter to reduce (PM) emissions Enclosure must have a roof and at least two complete walls, with side curtains and ventilation

12 Dry Abrasive Blasting Requirements Vented enclosure - Management and pollution prevention practices: Take measures to minimize excess dust in the surrounding area to reduce MFHAP emissions Enclose abrasive material storage areas and holding bins, seal chutes and conveyors transporting abrasive materials Operate all equipment according to manufacturers instructions

13 Dry Abrasive Blasting Requirements Objects greater than 8 Feet: Management and P2 Practices Must use low PM-emitting blast media (e.g., crushed glass, hematite, steel shot or aluminum oxide Do not re-use blast media unless contaminants have been removed by filtration or material screened to original size

14 Dry Abrasive Blasting Requirements Objects greater than 8 Feet: Management and P2 Practices Cont. Enclose abrasive material storage areas, holding bins, seal chutes and conveyors Operate all equipment used in the blasting operation according to manufacturers instructions Perform visible emissions monitoring

15 Dry Abrasive Blasting Requirements Objects greater than 8 Feet: Visible Emissions Testing Conduct visible emissions testing to demonstrate continuous compliance with management and pollution prevention practices Perform visual determinations of fugitive emissions using EPA Method 22 at the fence line nearest operation

16 Dry Abrasive Blasting Requirements Objects greater than 8 Feet: Graduated Testing Affected source must be tested daily for visible emissions with Method 22 for 10 consecutive days during operation If no visible emissions are observed, test once every 5 consecutive days of operation If no visible emissions are observed during 4 consecutive weekly Method 22 tests, test once per consecutive 21 days (month)

17 Dry Abrasive Blasting Requirements Objects greater than 8 Feet: Graduated Testing Cont. If no visible emissions are observed during 3 consecutive monthly Method 22 tests, test once every three months of operation If any visible emissions are observed during the weekly, monthly, or quarterly testing, the source must resume VE testing more frequently

24 Area Source Rule for: 9 Metal Fabrication & Finishing Welding Activity Final Rule Effective Date: July 23, 2008 National Emissions Standards for Hazardous Air Pollutants:

25 Welding Requirements Minimize emissions of MFHAP by implementing one or more management practices: Use welding processes with reduced fume generation capabilities (e.g., gas metal arc welding (GMAW); aka metal inert gas welding(MIG)); Use welding process variations (e.g., pulsed GMAW), which can reduce fume generation

26 Welding Requirements cont. Additional Management Practices: Use welding filler metals, shielding gases, carrier gases, or other process materials capable of reduced welding fume generation Optimize welding process variables (e.g., electrode diameter, voltage, amperage, welding angle, shield gas flow rate, travel speed) to reduce the amount of welding fume generated

27 Welding Requirements cont. Additional Management Practices: Use a welding fume capture and control system and operate according to manufacturers specifications.

28 Welding Requirements cont. Visual Emissions Testing: Welding operations using 2,000 pounds of welding rod per year must perform visible emissions testing from a vent, stack, exit, or opening from the building Welding metal fabrication and finishing operations must demonstrate continuous compliance via management practices and equipment standards Testing has a 3 tier compliance structure

29 Welding Requirements cont. Visual Emissions Testing: Tier I Welding compliance requires visual determinations of fugitive emissions using EPA Method 22 and allows the graduated testing schedule If visible emissions are present during any Method 22 test - corrective action is required For graduated schedule source resumes visible emissions testing in the previous, more frequent schedule

30 Welding Requirements cont. Visual Emissions Testing: Tier II 2 nd tier welding compliance must be implemented if visible emissions are detected for the 2 nd time in any consecutive 12-month period 2 nd tier requires corrective action and documentation of the detection of visible emissions and the corrective action taken Must perform a visual determination of emissions opacity using EPA Method 9

31 Welding Requirements cont. Visual Emissions Testing: Tier III 3 rd tier welding compliance includes the development and implementation of a Site- specific Welding Emissions Management Plan (SWMP) SWMP must be kept at the facility in a readily accessible location for inspector review Facility must report any exceedence of the 20 percent opacity limit on an annual basis along with their annual certification and compliance report

32 Initial Compliance Requirements Must certify that they have implemented all required management and pollution prevention practices Spray painting operations must certify compliance with use of PM filters in spray booths or spray rooms; use of approved spray delivery and cleaning systems; and proper training of workers in spray painting application techniques
