NAC444.683. Plan for monitoring water; suspension of monitoring requirements.

     1. The plan for monitoring water for a Class I site must provide a complete description of a system capable of monitoring the performance of the design of the site, including monitoring of the groundwater to detect the release of pollutants or contaminants from the municipal solid waste landfill unit into the waters of the State.

     2. The plan must:

     (a) Identify the location and construction of monitoring points;

     (b) Specify monitoring parameters and the frequency of monitoring those parameters;

     (c) Specify procedures for quality assurance for all field and laboratory work;

     (d) Provide for the semiannual submittal of monitoring data to the solid waste management authority;

     (e) Establish procedures which must be used if monitoring provides evidence of leachate migration; and

     (f) Comply with NAC 444.7481 to 444.7499, inclusive.

     3. The solid waste management authority may suspend monitoring requirements if the owner or operator of a Class I site demonstrates that there is no potential for migration of pollutants or contaminants from the site to waters of the State during the active life of the site, including the period for closure and postclosure. The demonstration must be:

     (a) Certified by a qualified groundwater scientist and approved by the solid waste management authority; and

     (b) Based on:

          (1) Measurements collected at a specific field site, sampling and an analysis of physical, chemical and biological processes affecting the fate and transportation of pollutants or contaminants; and

          (2) Predictions of the fate and transportation of the pollutants or contaminants that consider the maximum rate of the migration of contaminants and the impact of the pollutants or contaminants on public health and safety and the environment.
