Section 326IAC8-20-3. Overall requirements for industrial wastewater

   The owner or operator of a source subject to this rule shall ensure that all of the following are met:

(1) Except as otherwise exempted under subdivision (2), the owner or operator of a source that meets the applicability criteria in section 1 of this rule shall comply with the requirements in sections 4 through 12 of this rule.

(2) The following exemptions apply:

(A) Any source with an annual affected VOC loading in wastewater, as determined in accordance with section 9 of this rule, less than or equal to ten (10) megagrams (eleven and three-hundredths (11.03) tons) is exempt from the control requirements of section 4 of this rule.

(B) At any source with an annual affected VOC loading in wastewater, as determined in accordance with section 9 of this rule, greater than ten (10) megagrams (eleven and three-hundredths (11.03) tons), the owner or operator of the source may exempt from the control requirements of section 4 of this rule one (1) or more affected VOC wastewater streams for which the sum of the annual VOC loading in wastewater for all of the exempted streams is less than or equal to ten (10) megagrams (eleven and three-hundredths (11.03) tons).

(C) If compliance with the control requirements of section 4 of this rule would create a safety hazard in a waste management unit, the owner or operator may request U.S. EPA to exempt that waste management unit from the control requirements of section 4 of this rule. U.S. EPA shall approve the request if justified by the likelihood and magnitude of the potential injury and if U.S. EPA determines that reducing or eliminating the hazard is technologically or economically unreasonable. The approval shall occur when the department is informed, in writing, that U.S. EPA has no objections to this exemption.

(D) Wet weather retention basins are exempt from the requirements of this rule.
