Section 19.205 - Handling Facility Design Requirements(1)Storm Water Controls.(a)Performance Standard. Storm water controls shall prevent erosion, prevent the discharge of pollutants, protect the physical integrity of the handling facility, and be managed according to applicable standards established by the Department including, but not limited to, the wetlands protection regulations at 310 CMR 10.05(6)(b) and the Department's Storm Waster Policy. For purposes of meeting the stormwater standards established by the Department, recharge shall be permitted at the handling facility only where the recharge will not adversely impact the quality of groundwater leaving the site. Peak rate attenuation shall be in accordance with that described in 310 CMR 19.205(1)(b): Design Standards, and source controls and pollution prevention measures (including design of the handling facility) shall be implemented to prevent discharge of pollutants. This standard applies to the construction and operational phases of the handling facility.(b)Design Standards. Storm water controls shall be designed to: 1. prevent run-on or flow onto the waste or material handling or storage areas during the peak discharge from a 24 hour, 100-year storm;2. control the peak rate of run-off from the handling facility and paved areas of the site resulting from a 24 hour, 25-year storm.3. control the peak rate of run-off from the handling facility resulting from a 24 hour, 100-year storm, to the extent practicable, if an evaluation of the peak rate of run-off resulting from a 24-hour, 100-year storm indicates there will be flooding up or downstream of the site using the most recent precipitation atlas approved for use by the United States National Weather Service, or their predecessor the U.S. Weather Bureau, shall be used to determine the rainfall depth associated with the 100-year storm (currently Technical Paper-40 published May, 1961).(2)Equipment.(a) The operator shall provide equipment in adequate numbers and of appropriate type and size for the proper operation of the handling facility in accordance with good engineering practice and in compliance with 310 CMR 19.00. All compactor or other processing units shall be in duplicate with each unit capable of handling the expected design tons per day; except that only one compactor or processing unit may be satisfactory 1. where the handling facility will handle under 150 tons per day, or2. where adequate facilities to continue operation and/or an alternate method to handle all incoming refuse in an approved and sanitary manner in the event of a failure or breakdown is provided.(b) The operator shall make provisions for the routine maintenance of equipment to assure satisfactory performance capability for the various operations of the handling facility.(c) The operator shall provide at the site suitable shelter or protection for all equipment and necessary service supplies used in connection with the handling facility.(d) The operator shall make arrangments for providing standby equipment in the event of breakdown of regular equipment. Such standby equipment shall be available for use and shall be provided within 24 hours of breakdown; otherwise the handling facility shall be closed for receipt of wastes until equipment becomes available.(3)Weighing Facilities. The operator shall make provision on a continuous basis for the weighing or measuring of refuse delivered to the handling faiclity. Scales or other measuring devices may be required by the Department as follows:(a) The operator of existing or new handling facilities receiving 100 tons or more per day shall weigh all incoming solid waste.(b) Operators of handling facilities that receive less than 100 tons per day shall, on a daily basis, estimate the total weight and volume of waste delivered based upon the capacity of the vehicles which delivered solid waste to the facility.
