7 PTE Calculations Many questions:  Fuel Source?  Throughputs…?  Operational times?  Location?  Are these right?

8 To Be or Not to Be a Minor Source??? Manufacture PTE #’s  SO  NOx  VOC/TOC  Lead  PM & PM  CO0.936  Hg??? EPA Minor Thresholds  SO210  NOx10  VOC 5  Lead0.1  PM & PM10 10 & 5  CO10  HAPs (Hg)*10 * 10 tons of HAPs or combo of 25 tons total

9 Minnesota Pollution Control Agency  No MPCA Permit required  Health Department License  subpart 3 MN Administrative Rules 1.Smoke and Odor (nuisance) 2.Require no mercury controls 3.No greater than 20% opacity 4.Maintain 1200 degree flue gas temperature, 1600 degrees inside chamber

10 MPCA and EPA Guidance “ Good Engineering Practices” GEP – 1980’s Minimum – (downwash plume concerns) 1.5 x building height = stack height 1.5 x 12 ft = 18 ft Optimum 2.5 x building height = stack height 2.5 x 12 ft = 30 ft Compromised to a 24 foot stack in 4 foot sections Taller the stack = lessen the ground level impacts

11 Concerns for surrounding buildings Fire Hall Garage B and G Club District Offices OffceOffce Day Care Residences Library Health Div 130’ 203’ Going with 24ft stack from top of burner

12 Still Questions  Waiting for guidance from EPA retired!%#  MPCA and U of Mn study on dental algams – 3yr  Chemotherapy and other drugs – accounted for?  PTE does include natural gas as fuel source Nox levels higher?  No one is quite sure on any aspect… touchy political subject

13 What you can do…  Even when there is not a direct regulation use other regulations to enforce  e.g. nuisance, opacity  Find “Good Practices”  Work with other regulatory agencies  Find and use information outlets  Keep a positive relationship with source
