Utah Admin. Code R315-308-1 - Applicability

(1) Each existing solid waste management facility that is required to perform groundwater monitoring shall comply with the groundwater monitoring requirements according to the compliance schedule as established by the director during the permitting or the permit renewal process.

(2) Before the acceptance of waste, each new solid waste management facility that is required to perform groundwater monitoring shall have:

(a) a site specific groundwater monitoring plan approved by the director; and

(b) the groundwater monitoring system complete and operational.

(3) Groundwater monitoring requirements may be waived by the director if the owner or operator of a solid waste disposal facility can demonstrate that there is no potential for migration of hazardous constituents from the facility to the groundwater during the active life of the facility and the post-closure care period. This demonstration shall be certified by a qualified groundwater scientist and approved by the director, and shall be based upon:

(a) site specific field collected measurements, sampling, and analysis of physical, chemical, and biological processes affecting contaminant fate and transport; and

(b) contaminant fate and transport predictions that maximize contaminant migration and consider impacts on human health and the environment.

(4) Once a groundwater monitoring system and program has been established at a disposal facility, groundwater monitoring shall continue to be conducted throughout the active life, closure, and post-closure care periods as specified by the director.

(5) A facility that has a groundwater monitoring alternative approved under Subsection R315-302-1(2)(e)(vi) is subject to the standards specified in Subsection R315-303-2(1) and the approved alternative shall be revoked by the director if the operation of the facility impacts groundwater.
