Section 326 IAC 6-4-3 - Multiple sources of fugitive dustAuthority: IC 13-14-8; IC 13-17-3-4; IC 13-17-3-11
Affected: IC 13-1-1
Sec. 3.
(a) The allowable particles shall refer to the total of all particles leaving the boundaries or crossing the property lines of any source of fugitive dust regardless of whether from a single operation or a number of operations. If the source is determined to be comprised of two (2) or more legally separate persons, each shall be held proportionately responsible on the basis of contributions by each person as determined by microscopic analysis. In such cases, samples shall be taken downwind from the combination of sources and at the fence line of each source.(b) No source which is contributing to a combined downwind fugitive dust concentration in excess of the limits of this rule ( 326 IAC 6-4) shall be required to reduce emissions if the concentrations at his property line are in compliance, unless all contributors are individually in compliance and a combined fugitive dust concentration still exceeds the limits of this rule ( 326 IAC 6-4). Each source shall then be required to reduce its emissions by like percentages to achieve an acceptable combined downwind concentration.(c) When all contributors are individually in compliance and no nuisance to the surrounding community is created, the commissioner may waive the requirement for further reduction in emissions by combined contributors.
