KLEINFELDER <br />(2) The survey plot and record of the location and quantity of asbestos - <br />containing waste disposed of within the disposal site required in <br />§61.154(f) have been fled with the administrator; and <br />(3) The site is subject to 40 CFR, Part 61, Subpart M. " <br />J -M Mfg. intends to meet these requirements and will complete revision of the facility deed on <br />or before the time that final grading has occurred on site. <br />6.2.3 WMU Cap <br />Capping was selected for closure of the WMUs because it is a technology that can isolate the <br />waste from the environment and control erosion. In addition, capping is a common technology <br />generally accepted by state and federal agencies. <br />6.2.3.1 Existing Regulations <br />Federal regulations (40 CFR, Part 61, Subpart M, Section 61.151) list five ways in which an <br />inactive asbestos disposal site can be closed: <br />1. The WMU can be left as -is as long as no visible emissions of asbestos are <br />evident. <br />2. The WMU can be capped with 6 inches of soil and then planted with some form <br />of vegetation to control erosion. <br />3. The WMU can be capped with 2 feet of soil without planting vegetation. <br />4. For sites with asbestos tailings, a binding agent can be sprayed on the surface to <br />control dust generation. <br />5. An alternative control method approved by regulatory agencies. <br />W DTSC law (Health and Safety Code Section 25143.7) states that "Waste containing asbestos <br />may be disposed of at any landfill which has waste discharge requirements issued by the <br />y regional water quality control board which allow the disposal of such waste, provided that the <br />wastes are handled and disposed of in accordance with the Toxic Substances Control Act and <br />CR14-92-12 Page 27 of 39 24-220109-F09 <br />Copyright 1992 Kleinfelder, Inc.
