18 AAC 60.840. Parameters for surface water monitoring and groundwater detection monitoring

(a) Unless a reduced list of parameters is designated under 18 AAC 60.850(a) , during detection monitoring the owner or operator of a Class I MSWLF shall monitor groundwater for all contaminants listed in 40 C.F.R. 258, Appendix I, as amended through December 6, 1995, which is adopted by reference. In addition, the department will, in its discretion, require the owner or operator to test for one or more of the constituents and parameters listed in Table J in this section.

(b) The owner or operator of a facility, other than a Class I MSWLF, subject to surface water or groundwater monitoring shall test for those parameters of 40 C.F.R. Part 258, Appendix I, adopted by reference in (a) of this section and of Table J, applied to the facility by the department. The department will determine which test parameters are required on a case-by-case basis after considering the following factors:

(1) the geological and hydrogeological characteristics of the site;

(2) the impact of manmade and natural features on the effectiveness of surface and groundwater monitoring;

(3) climatic factors that might influence the reliability of surface and groundwater monitoring procedures; and

(4) the effectiveness of indicator parameters in detecting a release.
