R315. Environmental Quality, Waste Management and Radiation Control, Waste Management.R315-321. Class VII Exploration and Production Waste Landfill Requirements.
R315-321-1. Applicability.
The requirements of Rule R315-321 apply to each Class VII Facility designed and operated as a landfill as defined in Subsection R315-301-2(41). Each unit in a Class VII Facility that qualifies as a solid waste surface impoundment shall meet the applicable standards specified in Rule R315-322.
R315-321-2. Class VII Landfill Standards for Performance.
Each Class VII landfill shall meet the standards for performance as specified in Section R315-303-2.
R315-321-3. Class VII Landfill Location Standards.
(1) A new Class VII landfill or the lateral expansion of an existing Class VII landfill shall be subject to the following location standards:
(a) the ecologically and scientifically significant natural area standards of Subsection R315-302-1(2)(a)(ii); and
(b) the standards found in Subsections R315-302-1(2)(c) through R315-302-1(2)(f).
(2) An existing Class VII landfill shall be subject to the following location standards:
(a) the ecologically and scientifically significant natural area standards of Subsection R315-302-1(2)(a)(ii);
(b) the floodplain standards of Subsection R315-302-1(2)(c)(ii); and
(c) the standards listed in Subsection R315-321-3(1) in effect at an existing facility to protect municipal drinking water, wetlands, and groundwater, before applying for a permit, shall be maintained for the life of the facility unless otherwise determined by the director.
(3) Location Standards Exemptions.
(a) Except for the standards listed in Subsection R315-321-3(3)(b), the director may grant an exemption from any location standard of Subsection R315-302-1(2) for a Class VII landfill, on a site-specific basis if the director determines that the exemption will cause no adverse impacts to human health or the environment. If an exemption is granted, the director may require that the facility have more stringent design, construction, monitoring program, or operational practice to protect human health or the environment.
(b) No exemptions shall be given for the following location standards at a Class VII landfill:
(i) ecologically and scientifically significant natural area standards of Subsection R315-302-1(2)(a)(ii);
(ii) floodplain standards, unless the exemption meets the criteria of Subsection R315-302-1(2)(c)(ii);
(iii) the location standards for wetlands for a new facility or lateral expansion of an existing facility, unless the exemption meets the criteria of Subsection R315-302-1(2)(d); or
(iv) the location standards for groundwater for a new facility or lateral expansion of an existing facility that accepts hazardous waste from very small quantity generators as defined in Subsection R315-260-10(c), unless the exemption meets the criteria of Subsection R315-302-1(2)(e)(vi).
R315-321-4. Class VII Landfill Requirements.
(1) Each Class VII landfill shall meet the following applicable requirements, as determined by the director:
(a) the plan of operation requirements of Subsection R315-302-2(2), except plans to control wind-blown litter and disease vectors as found in Subsections R315-302-2(2)(h) and R315-302-2(2)(k) are not required;
(b) the recordkeeping requirements of Subsections R315-302-2(3)(a), R315-302-2(3)(b)(i), R315-302-2(3)(b)(iii), R315-302-2(3)(b)(iv), and R315-302-2(3)(b)(vi);
(c) the reporting requirements of Subsection R315-302-2(4);
(d) the inspection requirements of Subsection R315-302-2(5); and
(e) for Class VII facilities with landfill cells that do not accept hazardous waste from a very small quantity generator as defined by Subsection R315-260-10(c), submit details of controls and employee training programs used to prevent the acceptance of hazardous waste.
(2) Standards for Design.
(a) The owner or operator of a Class VII landfill shall design the facility to control storm water run-on or run-off as specified in Subsections R315-303-3(1)(c) and R315-303-3(1)(d).
(b) Any container or tank storage area used to manage waste containing free liquids shall have secondary containment that:
(i) is free of cracks or gaps and is sufficiently impervious to contain leaks, spills, and accumulated precipitation until the collected material is detected and removed;
(ii) is sloped or otherwise designed and operated to drain and remove liquids resulting from leaks, spills, or precipitation;
(iii) has sufficient capacity to contain 10% of the volume of containers or the volume of the largest container, whichever is greater. Containers that do not contain free liquids need not be considered in this determination;
(iv) is designed and operated to prevent run-on into the containment system unless the system has sufficient excess capacity in addition to that required in Subsection R315-322-4(3)(b)(iii) to contain any run-on that might enter the system; and
(v) is operated to remove spilled or leaked waste and accumulated precipitation from the sump or collection area in as timely a manner as is necessary to prevent overflow of the collection system.
