Duprey, Director EPA Region VIII Waste Management Division (8—HWM) This is in response to your request received in November 1985 for guidance concerning the question of under what conditions, if any, it is acceptable to use water or other liquid chemical stabilizers to control wind dispersal of waste in a landfill cell. We believe that the use of nonhazardous liquids for wind dispersal control at hazardous waste landfills should not be subject to the restrictions under Section 3004(c)(3) of HSWA. This use must, of course, be limited to amounts necessary to comply with wind dispersal control requirements. Such amounts should be determined by regulatory authorities on a case—by—case basis. As stated in your memorandum, Sections 264.301(f) and 265.302(d) require the owner or operator of a landfill containing hazardous waste that is subject to wind dispersal to cover or otherwise manage the landfill to control such dispersal. Since the liquids that are used to control wind dispersal are usually nonhazardous (e.g., water), a response, to your question is contained in a guidance we have drafted concerning Section 3004(c)(3) (which addresses the placement of nonhazardous liquids in hazardous waste landfills) of the 1984 Hazardous and Solid Waste Amendments (HSWA) to RCRA. This draft guidance will be sent to the regional offices in the near future. ------- 2 OSWER POLICY DIRECTIVE ‘9487.O0—lA We believe that the language and legislative history of Section 3004(c)(3) specifically, and of Section 3004(c) generally, indicate that Congress’ primary concern in banning liquids was to control the placement of liquids in landfills for treatment, storage, and disposal. We believe, further, that Congress did not intend to require owners and operators to apply for an exemption for uses of nonhazardous liquids in or near a landfill that are necessary in order to comply with the technical requirements of the RCRA regulations. You also inquired in your memorandum how wind dispersal control, including the use of liquid agents, was being managed at other sites nationally, and under what conditions. It is unfortunate that we have littl.e information concerning the national management of wind dispersal. We do know, however, that the use of water appears to be a common management practice for control of wind dispersal for dust and particulate matter. Other methods include waste containerization, use of cover material (soil and other waste), and waste treatment before disposal (e.g., chemical fixation, carbon adsorption). We hope this response clarifies the issue. If you should have any additional comments or concerns, please contact Paul Cassidy, of my staff, at FTS—382—4682. Let me say finally that we were very impressed with your full and perceptive analysis of the issue of the limited use of liquids for controlling wind dispersal. cc: EPA Regions I — VII and IX — X ------- |
