2. (2) For demonstrating compliance with particulate standards, testing must be conducted using the following test methods, or alternative methods approved by DEQ:

   1. (a) For wood waste boilers — DEQ Method 5. Results must be corrected to 12% CO2, as follows

      1. (A) C(12% CO2) = C x 12/%CO2

      2. (B) As used in paragraph (A):

         C(12%CO2) = Particulate matter emission concentration corrected to 12% CO2;

         C = Particulate matter emission concentration as measured by Oregon DEQ Method 5; and

         % CO2 = Percent CO2 in the exhaust gas, as measured by EPA Method 3 (or equivalent) during each particulate matter test run.

   2. (b) For veneer dryers, wood material dryers, press and other process vents — DEQ Method 7; and
   3. (c) For air conveying systems — DEQ Method 5 or 8.

3. (3) For demonstrating compliance with opacity standards, observations must be made in accordance with EPA Method 9 or continuous opacity monitoring systems certified in accordance with the DEQ Continuous Monitoring Manual.
