The Undertaking Is Calling… A surprising potential minor source story Brandy Toft Air Quality Specialist Leech Lake Band of Ojibwe National Tribal Forum 2014
The Frantic Call… Cranes! Moon suits!! Crematory!!! INSTALLING NOW!!! Why don’t you know?!?!? What are YOU going to do???
Fire Hall Garage B and G Club District Offices OffceOffce Day Care Residences Library Health Div
“THE UNDERTAKER IS IN…” It’s not everyday that you get this call…
Chatting with the Undertaker Applied for City permits Unit from “residential area” Puzzled but Cooperative Will do what needs to be done…
Call MPCA Who has Crematory information? Call Laura Call who Laura directed me to – R5 Call R5 again Scratch head… Step 1 Step 2 Step 3 Step 4 Step 5 Step 6 Scratch head again…
PTE Calculations Many questions: Fuel Source? Throughputs…? Operational times? Location? Are these right?
To Be or Not to Be a Minor Source??? Manufacture PTE #’s SO20.234 NOx0.2808 VOC/TOC0.2808 Lead0.0001 PM & PM100.6552 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
Minnesota Pollution Control Agency No MPCA Permit required Health Department License 7011.1215 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
MPCA 7011.1235 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
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
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
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
