Version 2.0 Created March 5, 2015

Preamble

  • This technical standard is an industry standard as defined in section 1 of O. Reg. 419/05.
  • With respect to facilities, this standard applies to every facility that is part of a class identified by NAICS code 3211 (Sawmills and Wood Preservation), or 3212 (Veneer, Plywood and Engineered Wood Product Manufacturing), other than a facility that is part of the class identified by NAICS code 321114 (Wood Preservation) or 321211 (Hardwood Veneer and Plywood Mills).
  • With respect to contaminants, this standard applies only to acrolein.
  • In accordance with subsection 38(3) of O. Reg. 419/05, compliance with this industry standard in accordance with subsection 42 (5) or subsection 44(3) may reduce the regulatory burden applicable to facilities in this class.
  • All of the sources of contaminant that discharge acrolein that are associated with the above NAICS codes have been considered in this industry standard. As such, a person registered for this industry standard that meets the criteria set out in subsection 42(1) or subsection 44(1) of O.Reg. 419/05 is, in general, exempt from Part II of the Regulation in respect of the facility and acrolein. In other words, a facility that is registered under this industry standard does not have to include any source of contaminant associated with the NAICS code that applies to them in any future Emission Summary and Dispersion Modelling reports for acrolein. (For more information, please see the Introduction to the Technical Standards Publication.)
  • This standard contains requirements that relate to the following sources of contaminant:
    • oriented strand board direct fired rotary dryers
    • particle board rotary dryers
    • particle board dry dryers
    • fiberboard atmospheric refiners
    • small-scale lumber kilns
    • full-scale lumber kilns
    • wood-fired combustors
  • With respect to acrolein, the publication of this industry standard indicates that the following criteria in paragraph 3footnote 1 of subsection 38(1) of O. Reg. 419/05 are met:
    1. with respect to at least two facilities located in Ontario to which this standard applies, it is not economically feasible to comply with section 19 or 20 of O. Reg. 419/05, whichever is applicable,
    2. compliance, in accordance with subsection 42 (5) of O. Reg. 419/05, with this standard,
      1. is technically and economically feasible with respect to at least one facility located in Ontario to which this industry standard applies, and
      2. will permit efforts that would otherwise be made to comply with section 19 or 20 of O. Reg. 419/05 to be put to better use to protect the natural environment, having regard to subclause (i), and
      3. including this industry standard in “Technical Standards to Manage Air Pollution” is more efficient than having the Director consider separate requests under section 32 of O. Reg. 419/05 for approval of alterations to the standard for acrolein that would otherwise apply to facilities to which this industry standard applies.

1 Column 2 does not apply to an individual source of contaminant listed in subsection 4(1) if the person who discharges or causes or permits the discharge of the contaminant demonstrates that the combined average percentage diversion of dryer exhaust for all sources of contaminant for which parameters are identified under clause (a) of subsection 4(2) is at least 10%.

3 Dryer Exhaust Diversion must be determined in accordance with Footnote 6 or 7.

4 Diverted Volumetric Flow Rate may be determined using the position of the damper relative the position of the damper at full flow of the over-fire air fan (i.e 100% open damper position). For example, if the damper were 50% open, the diverted volumetric flow rate would be determined by multiplying the maximum flow rate of the over-fire air fan by 50%.

  1. measure the diverted volumetric low rate for the dryer at least every 15 minutes for a one hour period.
  2. determine the average hourly diverted volumetric flow rate for the dryer
  3. determine the total hourly volumetric exhaust flow rate at maximum dryer capacity.
  4. divide the value in step 2 by the value in step 3.
  5. repeat steps 1 through 4, for every hour that the dryer operated with furnish during a period of 24 consecutive hours.
  6. add up the values determined under step 5 and divide by the number of hours that the dryer operated with furnish during the period.

7 Determination of combined average percentage diversion of Dryer Exhaust Diversion over a 24-Hour Block.

When determining the combined percentage Dryer Exhaust Diversion for all dryers to which this parameter applies, the following steps shall be followed:

  1. For each dryer to which the dryer exhaust diversion parameter applies,
    1. measure the diverted volumetric low rate for the dryer at least every 15 minutes for a one hour period.
    2. determine the average hourly diverted volumetric flow rate for the dryer
    3. determine the total hourly volumetric exhaust flow rate at maximum dryer capacity.
  2. For each dryer to which the dryer exhaust diversion parameter applies, sum each value determined under step 1b for every hour that the dryer operated during a period of 24 consecutive hours and divide by the total number of hours that the dryer operated during the period.
  3. For each dryer to which the dryer exhaust diversion parameter applies, sum each value determined under step 1c for every hour that the dryer operated with furnish during a period of 24 consecutive hours divide by the total number of hours that the dryer operated with furnish during the period.
  4. Sum the values determined in step 3 for all dryers to which the dryer exhaust diversion parameter applies.
