CB sent me a letter that I received yesterday telling me the Indiana Department of Environmental Management(IDEM) has proposed regs for OWB.
-IDEM proposed that hydronic heaters that do not meet the Phase 2 emissions limit (0.32 lbs/million Btu heat output) must install a chimney to "extend at least five (5) feet higher than the peak of any roof structure: (1) located within one hundred fifty (150) feet of unit; and (2) not located on the same property on which the heater is installed."
-The IDEM is proposing that existing furnace owners comply with requirements that DID NOT exist when consumers purchased their OWB.
-The chimney height requirements should only be applied to the 41 appliances that have been documented, in the last 8.5 years by IDEM, as creating a nuisance for neighbors.
-IDEM proposed a seasonal prohibition that states, "No person shall operate an outdoor hydronic heater from May 1 to Sept. 30 unless the outdoor hydronic heater has been certified...to meet the Phase 2 emission limit" no matter where an owner lives.
-Even furnace owners who heat rural homes and businesses, farming operations, greenhouse operations, and people who live on their own wood lots will have to meet excessive seasonal prohibition.
(d) No person shall cause or allow the emission of a smoke plume from a outdoor hydronic heater to exceed an average of twenty percent (20%) opacity..."
- Opacity is subjective visual observation. Opacity was designed for large industrial emission sources. Many factors can make opacity observation virtually impossible to conduct, even for certified observers. A homeowner should not be expected to conduct their own opacity readings.
