§373-3.30 - Containment Buildings

(a) Applicability. The requirements of this section apply to owners or operators who store or treat hazardous waste in units designed and operated under subdivision (b) of this section. These provisions will become effective on February 18, 1993, although the owner or operator may notify the Commissioner of his or her intent to be bound by this section at an earlier time. The owner or operator is not subject to the definition of land disposal in 370.2(b) of this Title provided that the unit:

(1) is a completely enclosed, self-supporting structure that is designed and constructed of humanmade materials of sufficient strength and thickness to support themselves, the waste contents, and any personnel and heavy equipment that operate within the units, and to prevent failure due to pressure gradients, settlement, compression, or 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 such equipment with containment walls;

(2) has a primary barrier that is designed to be sufficiently durable to withstand the movement of personnel and handling equipment within the unit;

(3) if the unit is used to manage liquids, has:

(i) a primary barrier designed and constructed of materials to prevent migration of hazardous constituents into the barrier;

(ii) a liquid collection system designed and constructed of materials to minimize the accumulation of liquid on the primary barrier; and

(iii) a secondary containment system designed and constructed of materials to prevent migration of hazardous constituents into the barrier, with a leak detection and liquid collection system capable of detecting, collecting, and removing leaks of hazardous constituents at the earliest possible time, unless the unit has been granted a variance from the secondary containment system requirements under subparagraph (b)(2)(iv) of this section;

(4) has controls sufficient to prevent fugitive dust emissions, in order to meet the no visible emission standard in clause (b)(3)(i)('d') of this section; and

(5) is designed and operated to ensure containment and prevent the tracking of materials from the unit by personnel or equipment.

(b) Design and operating standards.

(1) All containment buildings must comply with the following design standards:

(i) The containment building must 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.

(ii) The floor and containment walls of the unit, including the secondary containment system if required under paragraph (2) of this subdivision, must 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, or 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 such equipment with containment walls. The unit must be designed so that it has sufficient structural strength to prevent collapse or other failure. All surfaces to be in contact with hazardous wastes must be chemically compatible with those wastes. DEC 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 light-weight doors and windows that meet these criteria:

('a') They provide an effective barrier against fugitive dust emissions under clause (3)(i)('d') of this subdivision; and

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

(iii) Incompatible hazardous wastes or treatment reagents must 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.

(iv) A containment building must 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.

(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 must include:

(i) 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).

(ii) a liquid collection and removal system to prevent the accumulation of liquid on the primary barrier of the containment building:

('a') The primary barrier must be sloped to drain liquids to the associated collection system; and

('b') Liquids and waste must be collected and removed to minimize hydraulic head on the containment system at the earliest practicable time that protects human health and the environment.

(iii) 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.

('a') The requirements of the leak detection component of the secondary containment system are satisfied by installation of a system that is, at a minimum:

('1') constructed with a bottom slope of 1 percent or more; and

('2') 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 3X10-5 m2/sec or more.

('b') If treatment is to be conducted in the building, an area in which such treatment will be conducted must be designed to prevent the release of liquids, wet materials, or liquid aerosols to other portions of the building.

('c') The secondary containment system must 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 373-3.10(d)(4)(i). In addition, the containment building must meet the requirements of 373-3.10(d)(2) and (3) to be considered an acceptable secondary containment system for a tank.)

(iv) For existing units other than 90-day generator units, the Commissioner may accept a determination by the EPA Regional Administrator to delay the secondary containment requirement for up to two years, based on a demonstration by the owner or operator that the unit substantially meets the standards of this section. In making this demonstration, the owner or operator must:

('a') have provided written notice to the EPA Regional Administrator of their request by February 18, 1993. This notification must describe the unit and its operating practices with specific reference to the performance of existing containment systems, and specific plans for retrofitting the unit with secondary containment;

('b') respond to any comments from the EPA Regional Administrator on these plans within 30 days; and

('c') fulfill the terms of the revised plans, if such plans are approved by the EPA Regional Administrator.

(3) Owners or operators of all containment buildings must:

(i) use controls and practices to ensure containment of the hazardous waste within the unit; and, at a minimum:

('a') maintain the primary barrier to be free of significant cracks, gaps, corrosion, or other deterioration that could cause hazardous waste to be released from the primary barrier;

('b') maintain the level of the stored/treated hazardous waste within the containment walls of the unit so that the height of any containment wall is not exceeded;

('c') take measures to prevent the tracking of hazardous waste out of the unit by personnel or by equipment used in handling the waste. An area must be designated to decontaminate equipment and any rinsate must be collected and properly managed; and

('d') take measures to control fugitive dust emissions such that any openings (doors, windows, vents, cracks, etc.) exhibit no visible emissions. In addition, all associated particulate collection devices (e.g., fabric filter, electrostatic precipitator) must be operated and maintained with sound air pollution control practices. This state of no visible emissions must be maintained effectively at all times during normal operating conditions, including when vehicles and personnel are entering and exiting the unit.

(ii) obtain certification by a qualified professional engineer registered in New York State that the containment building design meets the requirements of paragraphs (1) through (3) of this subdivision. For units placed into operation prior to February 18, 1993, this certification must be placed in the facility's operating record (on-site files for generators who are not formally required to have operating records) no later than 60 days after the date of initial operation of the unit. After February 18, 1993, PE certification will be required prior to operation of the unit.

(iii) 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, must repair the condition promptly, in accordance with the following procedures.

('a') Upon detection of a condition that has led to a release of hazardous waste (e.g., upon detection of leakage from the primary barrier) the owner or operator must:

('1') enter a record of the discovery in the facility operating record;

('2') immediately remove the portion of the containment building affected by the condition from service;

('3') determine what steps must be taken to repair the containment building, remove any leakage from the secondary collection system, and establish a schedule for accomplishing the cleanup and repairs; and

('4') within 7 days after the discovery of the condition, notify the Commissioner of the condition, and within 14 working days, provide a written notice to the Commissioner with a description of the steps taken to repair the containment building, and the schedule for accomplishing the work.

('b') The Commissioner 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.

('c') Upon completing all repairs and cleanup, the owner or operator must notify the Commissioner in writing and provide a verification, signed by a qualified, professional engineer registered in New York State, that the repairs and cleanup have been completed according to the written plan submitted in accordance with subclause (3)(iii)('a')('4') of this subdivision.

(iv) inspect and record in the facility's operating record, at least once every seven 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.

(4) For a containment building that contains both areas with and without secondary containment, the owner or operator must:

(i) design and operate each area in accordance with the requirements enumerated in paragraphs (1) through (3) of this subdivision;

(ii) take measures to prevent the release of liquids or wet materials into areas without secondary containment; and

(iii) maintain in the facility's operating log a written description of the operating procedures used to maintain the integrity of areas without secondary containment.

(5) Notwithstanding any other provision of this section, the Commissioner may waive requirements for secondary containment for a permitted containment building where the owner or operator demonstrates that the only free liquids in the unit are limited amounts of dust suppression liquids required to meet occupational health and safety requirements, and where containment of managed wastes and liquids can be assured without a secondary containment system.

(c) Closure and post-closure care.

(1) At closure of a containment building, the owner or operator must remove or decontaminate all waste residues, contaminated containment system components (liners, etc.), contaminated subsoils, and structures and equipment contaminated with waste and leachate, and manage them as hazardous waste unless 371.1(d)(4) of this Title applies. The closure plan, closure activities, cost estimates for closure, and financial responsibility for containment buildings must meet all of the requirements specified in sections 373-3.7 and 373-3.8 of this Subpart.

(2) If, after removing or decontaminating all residues and making all reasonable efforts to effect removal or decontamination of contaminated components, subsoils, structures, and equipment as required in paragraph (1) of this subdivision, the owner or operator finds that not all contaminated subsoils can be practicably removed or decontaminated, the owner or operator must close the facility and perform post-closure care in accordance with the closure and post-closure requirements that apply to landfills (373-2.14(g)). In addition, for the purposes of closure, post-closure, and financial responsibility, such a containment building is then considered to be a landfill, and the owner or operator must meet all of the requirements for landfills specified in sections 373-3.7 and 373-3.8 of this Subpart.

(d) - (k) Reserved.

§373-3.31 - Hazardous Waste Munitions and Explosives Storage

(a) Applicability. The requirements of this section apply to owners or operators who store munitions and explosive hazardous wastes, except as subdivision 373-1.1(a) provides otherwise. (NOTE: Depending on explosive hazards, hazardous waste munitions and explosives may also be managed in other types of storage units, including containment buildings (section 373-3.30 of this Subpart), tanks (section 373-3.10 of this Subpart), or containers (section 373-3.9 of this Subpart); See subdivision 374-1.13(f) of this Title for storage of waste military munitions).

(b) Design and operating standards.

(1) Hazardous waste munitions and explosives storage units must be designed and operated with containment systems, controls, and monitoring, that:

(i) Minimize the potential for detonation or other means of release of hazardous waste, hazardous constituents, hazardous decomposition products, or contaminated run-off, to the soil, ground water, surface water, and atmosphere;

(ii) Provide a primary barrier, which may be a container (including a shell) or tank, designed to contain the hazardous waste;

(iii) For wastes stored outdoors, provide that the waste and containers will not be in standing precipitation;

(iv) For liquid wastes, provide a secondary containment system that assures that any released liquids are contained and promptly detected and removed from the waste area, or vapor detection system that assures that any released liquids or vapors are promptly detected and an appropriate response taken (e.g., additional containment, such as overpacking, or removal from the waste area); and

(v) Provide monitoring and inspection procedures that assure the controls and containment systems are working as designed and that releases that may adversely impact human health or the environment are not escaping from the unit.

(2) Hazardous waste munitions and explosives stored under this Subpart may be stored in one of the following:

(i) Earth-covered magazines. Earth-covered magazines must be:

('a') Constructed of waterproofed, reinforced concrete or structural steel arches, with steel doors that are kept closed when not being accessed;

('b') Designed and constructed:

('1') To be of sufficient strength and thickness to support the weight of any explosives or munitions stored and any equipment used in the unit;

('2') To provide working space for personnel and equipment in the unit; and

('3') To withstand movement activities that occur in the unit; and

('c') Located and designed, with walls and earthen covers that direct an explosion in the unit in a safe direction, so as to minimize the propagation of an explosion to adjacent units and to minimize other effects of any explosion.

(ii) Above-ground magazines. Above-ground magazines must be located and designed so as to minimize the propagation of an explosion to adjacent units and to minimize other effects of any explosion.

(iii) Outdoor or open storage areas. Outdoor or open storage areas must be located and designed so as to minimize the propagation of an explosion to adjacent units and to minimize other effects of any explosion.

(3) Hazardous waste munitions and explosives must be stored in accordance with a Standard Operating Procedure specifying procedures to ensure safety, security, and environmental protection. If these procedures serve the same purpose as the security and inspection requirements of subdivision 373-3.2(e) of this Subpart, the preparedness and prevention procedures of section 373-3.3 of this Subpart, and the contingency plan and emergency procedures requirements of section 373-3.4 of this Subpart, then these procedures will be used to fulfill those requirements.

(4) Hazardous waste munitions and explosives must be packaged to ensure safety in handling and storage.

(5) Hazardous waste munitions and explosives must be inventoried at least annually.

(6) Hazardous waste munitions and explosives and their storage units must be inspected and monitored as necessary to ensure explosives safety and to ensure that there is no migration of contaminants out of the unit.

(c) Closure and post-closure care.

(1) At closure of a magazine or unit which stored hazardous waste under this section, the owner or operator must remove or decontaminate all waste residues, contaminated containment system components, contaminated subsoils, and structures and equipment contaminated with waste, and manage them as hazardous waste unless paragraph 371.1(d)(4) of this Title applies. The closure plan, closure activities, cost estimates for closure, and financial responsibility for magazines or units must meet all of the requirements specified in sections 373-3.7 and 373-3.8 of this Subpart, except that the owner or operator may defer closure of the unit as long as it remains in service as a munitions or explosives magazine or storage unit.

(2) If, after removing or decontaminating all residues and making all reasonable efforts to effect removal or decontamination of contaminated components, subsoils, structures, and equipment as required in paragraph (1) of this subdivision, the owner or operator finds that not all contaminated subsoils can be practicably removed or decontaminated, he or she must close the facility and perform post-closure care in accordance with the closure and post-closure requirements that apply to landfills (subdivision 373-2.14(g) of this Part).

§Appendix 25 - Recordkeeping Instructions

The recordkeeping provisions of sections 373-3.5(c) of this Title specify that an owner or operator must keep a written operating record at the facility. This Appendix provides additional instructions for keeping portions of the operating record.

The following information must be recorded, as it becomes available, and maintained in the operating record until closure of the facility in the following manner:

Records of each hazardous waste received, treated, stored, or disposed of at the facility which include the following:

(i) A description by its common name and the EPA Hazardous Waste Number(s) from Part 371 of this Title which apply to the waste. The waste description also must include the waste's physical form, i.e., liquid, sludge, solid, or contained gas. If the waste is not listed in section 371.4, the description also must include the process that produced it (for example, solid filter cake from production of _________________, EPA Hazardous Waste Number W051).

Each hazardous waste listed in section 371.4 of this Title, and each hazardous waste characteristic defined in section 371.3, has a four-digit EPA Hazardous Waste Number assigned to it. This number must be used for recordkeeping and reporting purposes. Where a hazardous waste contains more than one listed hazardous waste, or where more than one hazardous waste characteristic applies to the waste, the waste description must include all applicable EPA Hazardous Waste Numbers.

(ii) The estimated or manifest-reported weight, or volume and density, where applicable, in one of the units of measure specified in Table 1; and

(iii) The method(s) (by handling code(s) as specified in Table 2 and date(s) of treatment, storage or disposal.

§Appendix 28 - Tests for Significance

As required in section 373-3.6(d)(2) of this Title the owner or operator must use the Student's t-test to determine statistically significant changes in the concentration or value of an indicator parameter in periodic groundwater samples when compared to the initial background concentration or value of that indicator parameter. The comparison must consider individually each of the wells in the monitoring system. For three of the indicator parameters (specific conductance, total organic carbon, and total organic halogen) a single-tailed Student's t-test must be used to test at the 0.01 level of significance for significant increases over background. The difference test for pH must be a two-tailed Student's t-test at the overall 0.01 level of significance.

The Student's t-test involves a calculation of the value of a t-statistic for each comparison of the mean (average) concentration or value (based on a minimum of four replicate measurements) of an indicator parameter with its initial background concentrations or value. The calculated value of the t-statistic must then be compared to the value of the t-statistic found in a table for t-test of significant at the specified level of significance. A calculated value of t which exceeds the value of t found in the table indicates a statistically significant change in the concentration or value of the indicator parameter.

Formulate for calculation of the t-statistic and tables for t-test of significant can be found in most introductory statistics texts.

§Appendix 29 - Examples of Potentially Incompatible Waste

Many hazardous wastes, when mixed with other waste or materials at a hazardous waste facility, can produce effects which are harmful to human health and the environment, such as (1) heat or pressure, (2) fire or explosion, (3) violent reaction, (4) toxic dusts, mists, fumes or gases, or (5) flammable fumes or gases.

Below are examples of potentially incompatible wastes, waste components, and materials, along with the harmful consequences which result from mixing materials in one group with materials in another group. This list is intended as a guide to owners or operators of treatment, storage, and disposal facilities, and to enforcement and permit granting officials, to indicate the need for special precautions when managing these potentially incompatible waste materials or components.

This list is not intended to be exhaustive. An owner or operator must, as the regulation requires, adequately analyze the wastes so that the owner or operator can avoid creating uncontrolled substances or reactions of the type listed below, whether they are listed below or not.

It is possible for potentially incompatible wastes to be mixed in a way that precludes a reaction (e.g., adding acid to water rather than water to acid) or that neutralizes them (e.g., a strong acid mixed with a strong base), or that controls substances produced (e.g., by generating flammable gases in a closed tank equipped so that ignition cannot occur, and burning the gases in an incinerator).

In the lists below, the mixing of a Group A material with a Group B material may have the potential consequence as noted.
