NR 664.1101 NR 664.1101 Design and operating standards.

NR 664.1101(1) (1) All containment buildings shall comply with all of the following design standards:

NR 664.1101(1)(a) (a) The containment building shall be completely enclosed with a floor, walls and a roof to prevent exposure to the elements, (e.g., precipitation, wind, run-on), and to assure containment of managed wastes.

NR 664.1101(1)(b) (b) The floor and containment walls of the unit, including the secondary containment system if required under sub. (2), shall be designed and constructed of materials of sufficient strength and thickness to support themselves, the waste contents and any personnel and heavy equipment that operate within the unit, and to prevent failure due to pressure gradients, settlement, compression, uplift, physical contact with the hazardous wastes to which they are exposed, climatic conditions and the stresses of daily operation, including the movement of heavy equipment within the unit and contact of the equipment with containment walls. The unit shall be designed so that it has sufficient structural strength to prevent collapse or other failure. All surfaces to be in contact with hazardous wastes shall be chemically compatible with those wastes. The department will consider standards established by professional organizations generally recognized by the industry such as the American Concrete Institute (ACI) and the American Society of Testing Materials (ASTM) in judging the structural integrity requirements of this paragraph. If appropriate to the nature of the waste management operation to take place in the unit, an exception to the structural strength requirement may be made for lightweight doors and windows that meet both of the following criteria:

NR 664.1101(1)(b)1. 1. They provide an effective barrier against fugitive dust emissions under sub. (3) (a) 4.

NR 664.1101(1)(b)2. 2. The unit is designed and operated in a fashion that assures that wastes will not actually come in contact with these openings.

NR 664.1101(1)(c) (c) Incompatible hazardous wastes or treatment reagents may not be placed in the unit or its secondary containment system if they could cause the unit or secondary containment system to leak, corrode or otherwise fail.

NR 664.1101(1)(d) (d) A containment building shall have a primary barrier designed to withstand the movement of personnel, waste and handling equipment in the unit during the operating life of the unit and appropriate for the physical and chemical characteristics of the waste to be managed.

NR 664.1101(2) (2) For a containment building used to manage hazardous wastes containing free liquids or treated with free liquids (the presence of which is determined by the paint filter test, a visual examination or other appropriate means), the owner or operator shall include all of the following:

NR 664.1101(2)(a) (a) A primary barrier designed and constructed of materials to prevent the migration of hazardous constituents into the barrier (e.g., a geomembrane covered by a concrete wear surface).

NR 664.1101(2)(b) (b) A liquid collection and removal system to minimize the accumulation of liquid on the primary barrier of the containment building in compliance with both of the following:

NR 664.1101(2)(b)1. 1. The primary barrier shall be sloped to drain liquids to the associated collection system.

NR 664.1101(2)(b)2. 2. Liquids and waste shall be collected and removed to minimize hydraulic head on the containment system at the earliest practicable time.

NR 664.1101(2)(c) (c) A secondary containment system including a secondary barrier designed and constructed to prevent migration of hazardous constituents into the barrier, and a leak detection system that is capable of detecting failure of the primary barrier and collecting accumulated hazardous wastes and liquids at the earliest practicable time.

NR 664.1101(2)(c)1. 1. The requirements of the leak detection component of the secondary containment system are satisfied by installation of a system that is, at a minimum, both of the following:

NR 664.1101(2)(c)1.a. a. Constructed with a bottom slope of one percent or more.

NR 664.1101(2)(c)1.b. b. Constructed of a granular drainage material with a hydraulic conductivity of 1x10-2 cm/sec or more and a thickness of 12 inches (30.5 cm) or more, or constructed of synthetic or geonet drainage materials with a transmissivity of 3x105 m2/sec or more.

NR 664.1101(2)(c)2. 2. If treatment is to be conducted in the building, an area in which the treatment will be conducted shall be designed to prevent the release of liquids, wet materials or liquid aerosols to other portions of the building.

NR 664.1101(2)(c)3. 3. The secondary containment system shall be constructed of materials that are chemically resistant to the waste and liquids managed in the containment building and of sufficient strength and thickness to prevent collapse under the pressure exerted by overlaying materials and by any equipment used in the containment building. (Containment buildings can serve as secondary containment systems for tanks placed within the building under certain conditions. A containment building can serve as an external liner system for a tank, provided it meets the requirements of s. NR 664.0193 (4) (a). In addition, the containment building shall meet the requirements of s. NR 664.0193 (2) and (3) (a) and (b) to be considered an acceptable secondary containment system for a tank.)

NR 664.1101(3)(a)4. 4. Take measures to control fugitive dust emissions such that any openings (doors, windows, vents, cracks, etc.) exhibit no visible emissions (see 40 CFR part 60, appendix A, Method 22—Visual Determination of Fugitive Emissions from Material Sources and Smoke Emissions from Flares, incorporated by reference in s. NR 660.11). In addition, all associated particulate collection devices (e.g., fabric filter, electrostatic precipitator) shall be operated and maintained with sound air pollution control practices (see s. NR 439.055 for guidance). This state of no visible emissions shall be maintained effectively at all times during routine operating and maintenance conditions, including when vehicles and personnel are entering and exiting the unit.

NR 664.1101(3)(b) (b) Obtain certification by a qualified professional engineer that the containment building design meets the requirements of subs. (1) and (2) and this subsection.

NR 664.1101(3)(c) (c) Throughout the active life of the containment building, if the owner or operator detects a condition that could lead to or has caused a release of hazardous waste, repair the condition promptly, in accordance with all of the following procedures:

NR 664.1101(3)(c)1.d. d. Within 7 days after the discovery of the condition, notify the department of the condition, and within 14 working days provide a written notice to the department with a description of the steps taken to repair the containment building and the schedule for accomplishing the work.

NR 664.1101(3)(c)2. 2. The department will review the information submitted, make a determination regarding whether the containment building must be removed from service completely or partially until repairs and cleanup are complete and notify the owner or operator of the determination and the underlying rationale in writing.

NR 664.1101(3)(c)3. 3. Upon completing all repairs and cleanup the owner or operator shall notify the department in writing and provide a verification, signed by a qualified, registered professional engineer, that the repairs and cleanup have been completed according to the written plan submitted in accordance with subd. 1. d.

NR 664.1101(3)(d) (d) Inspect and record in the facility operating record, at least once every 7 days, data gathered from monitoring equipment and leak detection equipment as well as the containment building and the area immediately surrounding the containment building to detect signs of releases of hazardous waste.

NR 664.1101(4) (4) For containment buildings that contain areas both with and without secondary containment, the owner or operator shall do all of the following:
