Section 30.605 - Special Requirements for Wastewater Treatment Units(1)Applicability.(a) The requirements of 310 CMR 30.605 shall apply, and the other requirements of 310 CMR 30.500 through 30.900 shall not apply, to the following wastewater treatment units, as that term is defined in 310 CMR 30.010, provided that such units meet all of the requirements set forth in 310 CMR 30.605: 1. wastewater treatment units for the treatment of hazardous waste at the site of generation of the waste; and2. wastewater treatment units for the accumulation or storage, at the site of generation, of wastewater treatment sludge which is hazardous waste, prior to reintroduction of such sludge back into the wastewater treatment process.(b) The requirements of 310 CMR 30.605 shall not apply to a wastewater treatment unit which treats hazardous waste by a treatment process, method, or technique which is an integral part of the manufacturing process, as that term is defined in 310 CMR 30.010.(c) The requirements of 310 CMR 30.500 through 30.900 shall not apply to a wastewater treatment unit, as that term is defined in 310 CMR 30.010, which is permitted pursuant to 314 CMR 3.00. Hazardous waste activities at such wastewater treatment units are regulated pursuant to 314 CMR 8.05.(d)310 CMR 30.605(2) through (6) shall not apply, and all applicable requirements of 310 CMR 30.000 shall apply, to each wastewater treatment unit in which the owner or operator intends to or does treat any hazardous waste generated off the site where the wastewater treatment unit is located.(2)Management Standards. The owner or operator of each wastewater treatment unit shall comply with the requirements set forth in the following regulations:(a)310 CMR 30.511: Identification Number;(b)310 CMR 30.513: General Waste Analysis;(c)310 CMR 30.514(1): Security Standards;(d)310 CMR 30.515: General Inspection;(e)310 CMR 30.516: Personnel Training;(f)310 CMR 30.520 through 30.524: Contingency Plan, Emergency Procedures, preparedness and Prevention;(g)310 CMR 30.542: Operating Record;(h)310 CMR 30.543: Availability, Retention and Disposition of Records; and(i)310 CMR 30.560: General Requirements for Ignitable, Reactive, or Incompatible Wastes(3)Operation and Maintenance.(a) The owner or operator of each wastewater treatment unit shall ensure that the accumulation, storage, or treatment done in each unit does not: 1. Generate fire, explosion, violent reaction, or excessive heat or pressure;2. Produce uncontrolled toxic mists, fumes or gases in quantities which might threaten public health, safety or welfare or the environment;3. Produce uncontrolled flammable fumes or gases in quantities which might pose a risk of fire or explosion;4. Damage the structural integrity of the tank or equipment containing the waste; or5. Threaten public health, safety or welfare or the environment by any other means.(b) No person shall place hazardous waste or any other material into a wastewater treatment unit if such action might result in the unit, or any of its equipment, rupturing, leaking, abnormally corroding, or failing before the end of its intended life.(c) Each wastewater treatment unit shall be designed, constructed, operated and maintained so as to prevent hazardous waste from spilling or leaking into or on any land or water.(4)Additional Waste Analysis Requirements.(a) By not later than April 16, 1984, the owner or operator of each wastewater treatment unit in existence on October 15, 1983, shall submit a copy of the waste analysis plan prepared in compliance with 310 CMR 30.513 and 30.605(2)(b) to the Department and to the local sewer use authority with jurisdiction over the publicly owned treatment works, here in after in 310 CMR 30.605 called the POTW, into which the effluent from the wastewater treatment unit discharges.(b) In addition to complying with the waste analysis requirements of 310 CMR 30.513 and 30.605(2)(b), the owner or operator shall ensure that the waste analysis plan: 1. Provides for determining the average and maximum effluent flow in gallons per day of the treated waste to be discharged to the POTW.2. Provides for identifying the waste(s) and the EPA or Massachusetts hazardous waste number(s) of the waste(s) being treated; and3. Describes the treatment process used.(5)Location Standards. No person shall construct, maintain or operate a wastewater treatment unit at a site at which hazardous waste is first generated on or after October 15, 1983, unless the following requirements are complied with:(a) If such unit is to be located on land subject to flooding from the statistical 100-year frequency storm, as determined pursuant to 310 CMR 30.701(1)(a) and (b), it shall be floodproofed in compliance with 310 CMR 30.701(2).(b) If such unit is also an underground tank pursuant to 310 CMR 30.693(1), it shall not be located:1. within the watershed of a class A or class SA segment of a surface water body, as that term is defined pursuant to 310 CMR 30.010, unless the owner or operator applies to the Department for approval to construct, operate and maintain such a unit at such a location, and the Department has given such approval in writing; the Department may give such approval only if the Department is persuaded that there is no feasible alternative to treating, storing or accumulating the wastewater in an underground unit (e.g., another permitting authority requires that the waste be accumulated, stored or treated underground); or2. over an actual, planned, or potential public underground drinking water source, as that term is defined in 310 CMR 30.010, unless the owner or operator has applied to the Department for approval to construct, operate and maintain such a unit at such a location, and the Department has given such approval in writing. The Department may give such approval only if the Department is persuaded that there is no feasible alternative to treating, storing, or accumulating the wastewater in an underground unit (e.g., another permitting authority requires that the waste be accumulated, stored, or treated underground).(6)Closure Requirements. At closure of the unit, the owner or operator of a wastewater treatment unit shall remove all hazardous waste and hazardous waste residues from the unit. Such waste and residues shall be managed in compliance with 310 CMR 30.000.
