Section 58.01.01.700 - PARTICULATE MATTER - PROCESS WEIGHT LIMITATIONS01.Particulate Matter Emission Limitations. Sections 700 through 703 establish particulate matter emission limitations for process equipment and include the following definitions: (3-28-23) a. Process weight is defined as the total weight of all materials introduced into any source operation that may cause any emissions of particulate matter. Process weight includes solid fuels charged, but does not include liquid and gaseous fuels charged or combustion air. Water that occurs naturally in the feed material is considered part of the process weight. (3-28-23)b. Process weight rate is established as follows: (3-28-23)i. For continuous or long-run steady-state source operations, the total process weight for the entire period of continuous operation or for a typical portion thereof, divided by the number of hours of such period or portion thereof; and (3-28-23)ii. For cyclical or batch source operations, the total process weight for a period that covers a complete cycle of operation or an integral number of cycles, divided by the hours of actual process operation during such a period. Where the nature of any process or operation or the design of any equipment is such as to permit more than one (1) interpretation of this definition, the interpretation that results in the minimum value for allowable emission applies. (3-28-23)02.Minimum Allowable Emission. Notwithstanding the provisions of Sections 701 and 702, no source will be required to meet an emission limit of less than one (1) pound per hour. (3-28-23)03.Averaging Period. For the purposes of Sections 701 through 703, emissions must be averaged according to the following, whichever is the lesser period of time: (3-28-23) a. One (1) complete cycle of operation; or (3-28-23)b. One (1) hour of operation representing worst-case conditions for the emissions of particulate matter. (3-28-23)04.Test Methods and Procedures. The appropriate test method under Sections 700 thought 703 is EPA Method 5 contained in 40 CFR Part 60 or such comparable and equivalent methods approved in accordance with Subsection 157.02.d. Test methods and procedures must comply with Section 157. (3-28-23)Idaho Admin. Code r. 58.01.01.700
