Design and Operating Requirements

(1) Each applicant for a license for land treatment shall persuade the Department that the land treatment unit will be designed, constructed, operated and maintained in compliance with 310 CMR 30.654. (2) The owner or operator shall design, construct, operate, and maintain the land treatment unit to maximize the degradation, transformation, and immobilization of the hazardous constituents in the treatment zone. The owner or operator shall design, construct, operate and maintain the unit in accordance with all design and operating conditions that were used in the treatment demonstration pursuant to 310 CMR 30.653. At a minimum, the Department shall specify the following in each license for a land treatment unit: (a) The rate and method of waste application to the treatment zone; (b) Measures to control soil pH; (c) Measures to enhance microbial or chemical reaction (e.g., fertilization, tilling); (d) Measures to control the moisture content of the treatment zone; and (e) The maximum quantity of waste that can be applied to the treatment zone over the operating life of the facility. (3) Hazardous waste shall not be applied to soil which is frozen, covered by ice or snow, and/or saturated with water. Hazardous waste shall not be applied to soil during any period of rainfall. (4) Hazardous waste shall not be applied to land with a slope of greater than 4%. (5) The owner or operator shall design, construct, operate and maintain the treatment zone to minimize run-off of hazardous constituents during the active life of the land treatment unit. (6) The owner or operator shall design, construct, operate and maintain a run-off management system to collect and control at least the water volume resulting from a 24 hour, 100-year storm. If the collected run-off is hazardous waste pursuant to 310 CMR 30.100, it shall be managed as hazardous waste in compliance with 310 CMR 30.000. If the collected run-off is discharged to surface water or groundwater, it is subject to regulation pursuant to M.G.L. c. 21 § 43. (7) The owner or operator shall design, construct, operate, and maintain a run-on control system capable of preventing flow onto the treatment zone during peak discharge from at least a 100-year storm. (8) To maintain the design capacity of the system, collection and holding facilities (e.g., tanks or basins) associated with run-on and run-off control systems shall be emptied or otherwise managed expeditiously after storms. (9) If the treatment zone contains particulate matter which may be subject to wind dispersal, the owner or operator shall manage the unit to control wind dispersal. (10) The owner or operator shall inspect the unit weekly and after storms to detect evidence of: (a) Deterioration, malfunctions, or improper operation of run-on and run-off control systems; and (b) Improper functioning of wind-dispersal control measures. (11) The growing of any food chain crop on the active portion or the closed portion of a land treatment facility is prohibited.
