OTTENWELLER OPERATES TWO PAINT BOOTHS CONSTRUCTED IN 1995 USING DRY FILTERS AS CONTROL. OTTENWELLER PAINTS MISCELLANEOUS METAL PARTS THAT ARE CONSTRUCTION EQUIPMENT COMPONENTS. THE PAINT BOOTHS ARE SUBJECT TO THE NATIONAL EMISSIN STANDARDS FOR HAZARDOUS AIR POLLUTANTS FOR MISCELLANEOUS METAL PART AND PRODUCTS SURFACE COATING (MACT), 40 CFR,PART 63, SUBPART MMMM. OTTENWELLER IS CHOOSING TO COMPLY WITH MACT BY COMPLYING WITH AN EMISSION RATE WITHOUT ADD-ON CONTROLS. THE ORGANIC HAP EMISSION RATE OF THE COATINGS, THINNERS AND/OR OTHER ADDITIVES AND CLEANING MATERIALS USED IN THE COATING OPERATIONS MUST BE LESS THAN OR EQUAL TO 2.6 LBS ORGANIC HAP PER GALLON OF COATING SOLIDS CALCULATED AS A ROLLING 12 MONTH EMISSION RATE AND DETERMINED ON A MONTHLY BASIS. OTTENWELLER DID NOT MEET THE 2.6 LBS OF ORGANIC HAP PER GALLON OF COATING SOLIDS ROLLING 12 MONTH AVERAGE FROM JANUARY 2008 TO AUGUST 2008.
TO COME INTO COMPLIANCE, OTTENWELLER INSTALLED A NEW PAINT MIXING SYSTEM ON ONE OF THE COATING LINES AND CHANGED MANY OF THEIR COATINGS, SOLVENTS AND THINNERS TO LOW HAP PRODUCTS.
