18 Alaska Admin. Code § 60.225

Current through May 31, 2024

Section 18 AAC 60.225 - Surface water requirements

(a) The owner or operator of a solid waste disposal facility may not allow the placement of solid waste in surface water unless that placement is allowed in a permit issued under AS 46.03.100 and this chapter.

(b) Except for an inert waste landfill, an asbestos landfill, or a Class III MSWLF that meets the standards in 18 AAC 60.300(c) (3)(B), the owner or operator of a landfill shall

(1) remove all ponded water that is in contact with waste within seven days after the formation of the pond unless another dewatering schedule is specified in a permit issued under AS 46.03.100 and this chapter;

(2) if the department determines that a control system for stormwater run-off is necessary to prevent the landfill contributing to siltation or flooding problems in nearby surface water bodies, construct and maintain a control system capable of containing and controlling the run-off from a 24-hour, 25-year storm; and

(3) prevent, contain, or control visible leachate seeps at the boundary of the waste management area.

(c) Except for a Class III MSWLF that meets the conditions of 18 AAC 60.300(c) (3)(B), or a Class I MSWLF with a research, development, and demonstration permit under 18 AAC 60.213 that allows the Class I MSWLF to utilize methods that vary from the requirements of this subsection, the owner or operator of a solid waste disposal facility shall construct and maintain a run-on control system that will prevent run-on from flowing onto the active portion of the facility. The control system must be capable of handling the peak discharge from a 25-year storm.

(d) The owner or operator of an inert waste landfill, an asbestos landfill, or a Class III MSWLF that meets the standards of 18 AAC 60.300(c) (3)(B) shall

(1) minimize contact between stormwater and the waste;

(2) construct and operate the landfill so that seasonal flooding is temporary in duration and ponded water is removed within 30 days; and

(3) prevent, contain, or control visible leachate seeps at the boundary of the waste management area if the department determines that leachate control measures are necessary to prevent a potential threat to public health, safety, or welfare.
