(1) For purposes of this subchapter, the department adopts and incorporates by reference:

(a) Test Methods for Evaluating Solid Waste, Physical/Chemical Methods, EPA publication SW‐846, Third Edition, Final Updates I (1993), II (1995), IIA (1994), IIB (1995), III (1997), IIIA (1999), IIIB (2005), IV (2008), and V (2015), which may be obtained at https://www.epa.gov/hw-sw846/sw-846-compendium or by contacting the National Technical Information Service, 5301 Shawnee Road, Alexandria, VA 22312 or 1 (800) 553-687;

(b) Montana Risk-based Corrective Action Guidance for Petroleum Releases, (May 2018) as the analytical methodology landfarms must utilize and Table 1 of the Montana Risk-based Corrective Action Guidance for Petroleum Release as the standards for compliance with remediation requirements outlined in ARM 17.50.1617. A copy of the Montana Risk-based Corrective Action Guidance for Petroleum Releases, (May 2018) may be obtained at http://deq.mt.gov/Land/lust or by contacting MDEQ at P.O. Box 200901, Helena, MT 59620-0901 or 1 (406) 444-6435.
