(a) Applicability.
The requirements of this section apply to owners or operators of facilities that use tank systems for storing or treating hazardous waste, except as otherwise provided in paragraphs (1), (2) and (3) of this subdivision or in section 373-3.1 of this Subpart.
(1) Tank systems that are used to store or treat hazardous waste which contains no free liquids and that are situated inside a building with an impermeable floor are exempt from the requirements of subdivision (d) of this section. To demonstrate the absence or presence of free liquids in the stored/treated waste, the following test must be used: method 9095B (paint filter liquids test) as described in “Test Methods for Evaluating Solid Waste, Physical/Chemical Methods,” EPA Publication No. SW-846 as incorporated by reference in section 370.1(e) of this Title.
(2) Tank systems, including sumps, as defined in section 370.2(b) of this Title, that serve as part of a secondary containment system to collect or contain releases of hazardous wastes are exempted from the requirements in paragraph (d)(1) of this section.
(3) Tanks, sumps, and other collection devices used in conjunction with drip pads, as defined in section 370.2(b) of this Title and regulated under section 373-3.23 of this Subpart must meet the requirements of this section.
(b) Assessment of existing tank system's integrity.
(1) For each existing tank system that does not have secondary containment meeting the requirements of subdivision (d) of this section, the owner or operator must determine that the tank system is not leaking or is unfit for use. Except as provided in paragraph (3) of this subdivision, the owner or operator must obtain and keep on file at the facility a written assessment reviewed and certified by an independent, qualified, professional engineer registered in New York that attests to the tank system's integrity by December 25, 1989. The certification must be consistent with the applicable provisions of section 373-1.4(a)(5)(iv) of this Part.
(2) This assessment must determine that the tank system is adequately designed and has sufficient structural strength and compatibility with the wastes to be stored or treated to ensure that it will not collapse, rupture, or fail. At a minimum, this assessment must consider the following:
(i) design standards, if available, according to which the tank and ancillary equipment were constructed;
(ii) hazardous characteristics of the wastes that have been or will be handled;
(iii) existing corrosion-protection measures;
(iv) documented age of the tank system, if available, (otherwise, an estimate of the age); and
(v) results of a leak test, internal inspection, or other tank integrity examination such that:
(a) for nonenterable underground tanks, this assessment must consist of a leak test that is capable of taking into account the effects of temperature variations, tank end deflection, vapor pockets, and high water table effect; and
(b) for other than nonenterable underground tanks and for ancillary equipment, this assessment must be either a leak test, as described above, or an internal inspection and/or other tank integrity examination certified by an independent, qualified, professional engineer registered in New York that addresses cracks, leaks, corrosion and erosion. The certification must be consistent with the applicable provisions of section 373-1.4(a)(5)(iv) of this Part.
Note:
The practices described in the American Petroleum Institute (API) publication, Guide for Inspection of Refinery Equipment, Chapter XIII, “Atmosphere and Low-Pressure Storage Tanks,” 4th edition, 1981, may be used, where applicable, as guidelines in conducting an integrity examination of an other than nonenterable underground tank system.
(3) Tank systems that store or treat materials that become hazardous wastes after December 25, 1988, must conduct this assessment within 12 months after the date that the waste becomes a hazardous waste.
(4) If, as a result of the assessment conducted in accordance with paragraph (1) of this subdivision, a tank system is found to be leaking or unfit for use, the owner or operator must comply with the requirements of subdivision (g) of this section.
(c) Design and installation of new tank systems or components.
(1) Owners or operators of new tank systems or components must ensure that the foundation, structural support, seams, connections, and pressure controls (if applicable) are adequately designed and that the tank system has sufficient structural strength, compatibility with the wastes to be stored or treated, and corrosion protection so that it will not collapse, rupture or fail. The owner or operator must obtain a written assessment reviewed and certified by an independent, qualified, professional engineer registered in New York attesting that the system has sufficient structural integrity and is acceptable for the storing and treating of hazardous waste. The certification must be consistent with the applicable provisions of section 373-1.4(a)(5)(iv) of this Part. This assessment must include, at a minimum, the following information:
(i) design standards according to which the tanks and ancillary equipment is or will be constructed;
(ii) hazardous characteristics of the wastes to be handled;

(a) factors affecting the potential for corrosion, including but not limited to:
(1) soil moisture content;
(2) soil pH;
(3) soil sulfides level;
(4) soil resistivity;
(5) structure to soil potential;
(6) influence of nearby underground metal structures (e.g.,piping);
(7) stray electric current; and
(8) existing corrosion-protection measures (e.g., coating, cathodic protection); and
(b) the type and degree of external corrosion-protection that are needed to ensure the integrity of the tank system during the use of the tank system or component, consisting of one or more of the following:
(1) corrosion-resistant materials of construction such as special alloys, fiberglass-reinforced plastic;
(2) corrosion-resistant coating (such as epoxy or fiberglass) with cathodic protection (e.g., impressed current or sacrificial anodes); and
(3) electrical isolation devices such as insulating joints and flanges;
Note:
The practices described in the National Association of Corrosion Engineers (NACE) standard, “Recommended Practice (RP-02-85) Control of External Corrosion on Metallic Buried, Partially Buried, or Submerged Liquid Storage Systems,” and the American Petroleum Institute (API) Publication 1632, “Cathodic Protection of Underground Petroleum Storage Tanks and Piping Systems,” may be used, where applicable, as guidelines in providing corrosion-protection for tank systems.
(iv) for underground tank system components that are likely to be affected by vehicular traffic, a determination of design or operational measures that will protect the tank system against potential damage; and
(v) design considerations to ensure that:
(a) tank foundations will maintain the load of a full tank;
(b) tank systems will be anchored to prevent flotation or dislodgement where the tank system is placed in a saturated zone, or is located within a seismic fault zone; and
(c) tank systems will withstand the effects of frost heave.
(2) The owner or operator of a new tank system must ensure that proper handling procedures are followed to prevent damage to the system during installation. Prior to covering, enclosing, or placing a new tank system or component in use, an independent, qualified installation inspector or an independent, qualified, professional engineer registered in New York, either of whom is trained and experienced in the proper installation of tank systems, must inspect the system or component for the presence of any of the following items:
(i) weld breaks;
(ii) punctures;
(iii) scrapes of protective coatings;
(iv) cracks;
(v) corrosion; and
(vi) other structural damage or inadequate construction or installation.
All discrepancies must be remedied before the tank system is covered, enclosed, or placed in use.
(3) New tank systems or components and piping that are placed underground and that are backfilled must be provided with a backfill material that is a noncorrosive, porous, homogeneous substance and that is carefully installed so that the backfill is placed completely around the tank and compacted to ensure that the tank and piping are fully and uniformly supported.
(4) All new tanks and ancillary equipment must be tested for tightness prior to being covered, enclosed, or placed in use. If a tank system is found not to be tight, all repairs necessary to remedy the leaks in the system must be performed prior to the tank system being covered, enclosed, or placed in use.
(5) Ancillary equipment must be supported and protected against physical damage and excessive stress due to settlement, vibration, expansion or contraction.
Note:
The piping system installation procedures described in American Petroleum Institute (API) publication 1615 (November 1979), Installation of Underground Petroleum Storage Systems, or ANSI standard B31.3, “Petroleum Refinery System,” may be used, where applicable, as guidelines for proper installation of piping systems.
(6) The owner or operator must provide the type and degree of corrosion-protection necessary, based on the information provided under subparagraph (1)(iii) of this subdivision, to ensure the integrity of the tank system during use of the tank system. The installation of a corrosion-protection system that is field-fabricated must be supervised by an independent corrosion expert to ensure proper installation.
(7) The owner or operator must obtain and keep on file at the facility written statements by those persons required to certify the design of the tank system and supervise the installation of the tank system in accordance with the requirements of paragraphs (2)-(6) of this subdivision to attest that the tank system was properly designed and installed and that repairs, pursuant to paragraphs (2) and (4) of this subdivision were performed. These written statements must also include the certification statement as required in section 373-1.4(a)(5)(iv) of this Part.
(d) Containment and detection of releases.
(1) In order to prevent the release of hazardous waste or hazardous constituents to the environment, secondary containment that meets the requirements of this section must be provided (except as provided in paragraphs [6] and [7] of this subdivision):
(i) for all new tank systems or components, prior to their being put into service and for existing tank systems or components; and

(2) Secondary containment systems must be:
(i) designed, installed, and operated to prevent any migration of wastes or accumulated liquid out of the system to the soil, ground water, or surface water at any time during the use of the tank system; and
(ii) capable of detecting and collecting releases and accumulated liquids until the collected material is removed.
(3) To meet the requirements of paragraph (2) of this subdivision, secondary containment systems must be at a minimum:
(i) constructed of or lined with materials that are compatible with the wastes to be placed in the tank system and must have sufficient strength and thickness to prevent failure due to pressure gradients (including static head and external hydrological forces), physical contact with the waste to which they are exposed, climatic conditions, the stress of installation, and the stress of daily operation (including stresses from nearby vehicular traffic);
(ii) placed on a foundation or base capable of providing support to the secondary containment system, providing resistance to pressure gradients above and below the system, and preventing failure due to settlement, compression, or uplift;
(iii) provided with a leak detection system that is designed and operated so that it will detect the failure of either the primary and secondary containment structure or any release of hazardous waste or accumulated liquid in the secondary containment system within 24 hours, or at the earliest practicable time if the existing detection technology or site conditions will not allow detection of a release within 24 hours; and
(iv) sloped or otherwise designed or operated to drain and remove liquids resulting from leaks, spills, or precipitation. Spilled or leaked waste and accumulated precipitation must be removed from the secondary containment system within 24 hours, or in as timely a manner as is possible to prevent harm to human health or the environment, if removal of the released waste or accumulated precipitation cannot be accomplished within 24 hours.
Note:
If the collected material is a hazardous waste under Part 371 of this Title, it is subject to management as a hazardous waste in accordance with all applicable requirements of Parts 372 through 374 and 376 of this Title. If the collected material is discharged through a point source to waters of the United States, it is subject to the requirements of Parts 700, 701 and 750 of this Title. If discharged to publicly owned treatment works (POTWs), it is subject to the requirements of section 307 of the Clean Water Act, as amended. If the collected material is released to the environment, it may be subject to the reporting requirements of 40 CFR Part 302.
(4) Secondary containment for tanks must include one or more of the following devices:
(i) a liner (external to the tank);
(ii) a vault;
(iii) a double-walled tank; or

(b) protected, if constructed of metal, from both corrosion of the primary tank interior and the external surface of the outer shell; and
(c) provided with a built-in, continuous leak detection system capable of detecting a release within 24 hours or at the earliest practicable time, if the owner or operator can demonstrate to the commissioner, and the commissioner concurs, that the existing leak detection technology or site conditions will not allow detection of a release within 24 hours.
Note:
The provisions outlined in the Steel Tank Institute's (STI) Standard for Dual Wall Underground Steel Storage Tank may be used as guidelines for aspects of the design of underground steel double-walled tanks.
(6) Ancillary equipment must be provided with full secondary containment (e.g., trench, jacketing, double-walled piping) that meets the requirements of paragraphs (2) and (3) of this subdivision except for:

(7) The owner or operator may obtain a variance from the requirements of this subdivision if the commissioner finds, as a result of a demonstration by the owner or operator, either: that alternative design and operating practices together with location characteristics will prevent the migration of hazardous waste or hazardous constituents into the ground water or surface water at least as effectively as secondary containment during the active life of the tank system; or that in the event of a release that does migrate to ground water or surface water, no substantial present or potential hazard will be posed to human health or the environment. New underground tank systems may not, per a demonstration in accordance with subparagraph (ii) of this paragraph, be exempted from the secondary containment requirements of this subdivision. Application for a variance as allowed in this paragraph does not waive compliance with the requirements of this section for new tank systems.
(i) In deciding whether to grant a variance based on a demonstration of equivalent protection of ground water and surface water, the commissioner will consider:
(a) the nature and quantity of the waste;
(b) the proposed alternate design and operation;
(c) the hydrogeologic setting of the facility, including the thickness of soils between the tank system and ground water; and
(d) all other factors that would influence the quality and mobility of the hazardous constituents and the potential for them to migrate to ground water or surface water.
(ii) In deciding whether to grant a variance, based on a demonstration of no substantial present or potential hazard, the commissioner will consider:
(a) the potential adverse effects on ground water, surface water, and land quality taking into account:
(1) the physical and chemical characteristics of the waste in the tank system, including its potential for migration;
(2) the hydrogeological characteristics of the facility and surrounding land;
(3) the potential for health risks caused by human exposure to waste constituents;
(4) the potential for damage to wildlife, crops, vegetation, and physical structures caused by exposure to waste constituents; and
(5) the persistence and permanence of the potential adverse effects;
(b) the potential adverse effects of a release on ground water quality, taking into account:
(1) the quantity and quality of ground water and the direction of ground water flow;
(2) the proximity and withdrawal rates of water in the area;
(3) the current and future uses of ground water in the area; and
(4) the existing quality of ground water, including other sources of contamination and their cumulative impact on the ground water quality;
(c) the potential adverse effects of a release on surface water quality, taking into account:
(1) the quantity and quality of ground water and the direction of ground water flow;
(2) the patterns of rainfall in the region;
(3) the proximity of the tank system to surface waters;
(4) the current and future uses of surface waters in the area and any water quality standards established for those surface waters; and
(5) the existing quality of surface water, including other sources of contamination and the cumulative impact on surface water quality; and
(d) the potential adverse effects of a release on the land surrounding the tank system, taking into account:
(1) the patterns of rainfall in the region; and
(2) the current and future uses of the surrounding land.
(iii) The owner or operator of a tank system, for which a variance from secondary containment had been granted in accordance with the requirements of subparagraph (i) of this paragraph, at which a release of hazardous waste has occurred from the primary tank system but has not migrated beyond the zone of engineering control (as established in the variance), must:
(a) comply with the requirements of subdivision (g) of this section, except paragraph (4); and
(b) decontaminate or remove contaminated soil to the extent necessary to:
(1) enable the tank system, for which the variance was granted, to resume operation with the capability for the detection of and response to releases at least equivalent to the capability it had prior to the release; and
(2) prevent the migration of hazardous waste or hazardous constituents to ground water or surface water; and
(c) if contaminated soil cannot be removed or decontaminated in accordance with clause (b) of this subparagraph, comply with the requirements of paragraph (h)(2) of this section.
(iv) The owner or operator of a tank system, for which a variance from secondary containment had been granted in accordance with the requirements of subparagraph (i) of this paragraph, at which a release of hazardous waste has occurred from the primary tank system and has migrated beyond the zone of engineering control (as established in the variance), must:
(a) comply with the requirements of paragraphs (g)(1)-(4) of this section;
(b) prevent the migration of hazardous waste or hazardous constituents to ground water or surface water, if possible, and decontaminate or remove contaminated soil. If contaminated soil cannot be decontaminated or removed, or if ground water has been contaminated, the owner or operator must comply with the requirements of paragraph (h)(2) of this section; and
(c) provide secondary containment in accordance with the requirements of paragraphs (1)-(6) of this subdivision if repairing, replacing, or reinstalling the tank system, or reapply for a variance from secondary containment and meet the requirements for new tank systems in subdivision (c) of this section if the tank system is replaced. The owner or operator must comply with these requirements even if contaminated soil can be decontaminated or removed, and ground water or surface water has not been contaminated.
(8) The following procedures must be followed in order to request a variance from secondary containment.
(i) The commissioner must be notified in writing by the owner or operator that the owner or operator intends to conduct and submit a demonstration for a variance from secondary containment as allowed in paragraph (7) of this subdivision according to the following schedule:
(a) for existing tank systems, at least 24 months prior to the date that secondary containment must be provided in accordance with paragraph (1) of this subdivision; and
(b) for new tank systems, at least 30 days prior to entering into a contract for installation of the tank system.
(ii) As part of the notification, the owner or operator must also submit to the commissioner a description of the steps necessary to conduct the demonstration and a timetable for completing each of the steps.

(iii) The demonstration for a variance must be completed and submitted to the commissioner within 180 days after notifying the commissioner of intent to conduct the demonstration.
(iv) The commissioner will inform the public, through a newspaper notice, of the availability of the demonstration for a variance. The notice shall be placed in a daily or weekly major local newspaper of general circulation and shall provide at least 30 days from the date of the notice for the public to review and comment on the demonstration for a variance. The commissioner also will hold a public hearing, in response to a request or at his or her own discretion, whenever such a hearing might clarify one or more issues concerning the demonstration for a variance. Public notice of the hearing will be given at least 30 days prior to the date of the hearing and may be given at the same time as notice of the opportunity for the public to review and comment on the demonstration. These two notices may be combined.
(v) The commissioner will approve or disapprove the request for a variance within 90 days of receipt of the demonstration from the owner or operator and will notify in writing the owner or operator and each person who submitted written comments or requested notice of the variance decision. If the demonstration for variance is incomplete or does not include sufficient information, the 90-day time period will begin when the commissioner receives a complete demonstration, including all information necessary to make a final determination. If the public comment period in subparagraph (iv) of this paragraph is extended, the 90-day time period will be similarly extended.
(9) All tank systems, until such time as secondary containment meeting the requirements of this subdivision is provided, must comply with the following:
(i) for nonenterable underground tanks, a leak test that meets the requirements of subparagraph (b)(2)(v) of this section must be conducted at least annually;
(ii) for other than nonenterable underground tanks and for all ancillary equipment, an annual leak test, as described in subparagraph (i) of this paragraph, or an internal inspection or other tank integrity examination by an independent, qualified, professional engineer registered in New York that addresses cracks, leaks, corrosion, and erosion must be conducted at least annually. The owner or operator must remove the stored waste from the tank, if necessary, to allow the condition of all internal tank surfaces to be assessed;
Note:
The practices described in the American Petroletm Institute (API) publication Guide for Inspection of Refining Equipment, Chapter XIII, “Atmospheric and Low Pressure Storage Tanks”, 4th edition, 1981, may be used, when applicable, as guidelines for assessing the overall condition of the tank system.
(iii) the owner or operator must maintain on file at the facility a record of the results of the assessments conducted in accordance with subparagraphs (i)-(iii) of this paragraph; and
(iv) if a tank system or component is found to be leaking or unfit-for-use as a result of the leak test or assessment in subparagraphs (i)-(iii) of this paragraph, the owner or operator must comply with the requirements of subdivision (g) of this section.
(e) General operating requirements.
(1) Hazardous wastes or treatment reagents must not be placed in a tank system if they could cause the tank, its ancillary equipment, or the secondary containment system to rupture, leak, corrode, or otherwise fail.
(2) The owner or operator must use appropriate controls and practices to prevent spills and overflows from tank or secondary containment systems. These include at a minimum:
(i) spill prevention controls (e.g., check valves, dry disconnect couplings);

For the purposes of this subdivision, the term ‘operating day’ means any calendar day when manufacturing (or the functional equivalent for non-manufacturing operations) is taking place.
(1) The owner or operator must inspect, where present, at least once each operating day, data gathered from monitoring and leak detection equipment (e.g., pressure or temperature gauges, monitoring wells) to ensure that the tank system is being operated according to its design.
Note:
Section 373-3.2(f)(3) of this Subpart requires the owner or operator to remedy any deterioration or malfunction the owner or operator finds. Subdivision (g) of this section requires the owner or operator to notify the department within 24 hours of confirming a release. Also, 40 CFR part 302 (see section370.1[e] of this Title) may require the owner or operator to notify the National Response Center of a release.
(2) Except as noted under paragraph (3) of this subdivision, the owner or operator must inspect at least once each operating day:
(i) overfill/spill control equipment (e.g., waste-feed cutoff systems, bypass systems, and drainage systems) to ensure that it is in good working order;
(ii) above ground portions of the tank system, if any, to detect corrosion or releases of waste; and
(iii) the construction materials and the area immediately surrounding the externally accessible portion of the tank system, including the secondary containment system (e.g., dikes) to detect erosion or signs of releases of hazardous waste (e.g., wet spots, dead vegetation).
(3) Owners or operators of tank systems that either use leak detection equipment to alert facility personnel to leaks, or implement other established workplace practices to ensure leaks are promptly identified within 24 hours, must inspect at least weekly those areas described in subparagraphs (2)(i) through (iii) of this subdivision. Use of the alternate inspection schedule must be documented in the facility's operating record. This documentation must include a description of the established workplace practices at the facility.
(4) Ancillary equipment that is not otherwise secondarily contained, as described in subparagraph (d)(6)(i) through (iv) of this section, must be inspected at least once each operating day.
(5) The owner or operator must inspect cathodic protection systems, if present, according to, at a minimum, the following schedule to ensure that they are functioning properly:
(i) the proper operation of the cathodic protection system must be confirmed within six months after initial installation, and annually thereafter; and
(ii) all sources of impressed current must be inspected and/or tested, as appropriate, at least bimonthly (i.e., every other month).
Note:
The practices described in the National Association of Corrosion Engineers (NACE) standard, “Recommended Practice (RP-02-85) Control of External Corrosion on Metallic Buried, Partially Buried, or Submerged Liquid Storage Systems”, (see section 370.1[e] of this Title) and the American Petroleum Institute (API) publication, 1632, Cathodic Protection of Underground Petroleum Storage Tanks and Piping Systems, (see section 370.1[e] of this Title) may be used, where applicable, as guidelines in maintaining and inspecting cathodic protection systems.
(6) The owner or operator must document in the operating record of the facility an inspection of those items in paragraphs (1) through (5) of this subdivision.
(g) Response to leaks or spills and disposition of leaking or unfit-for-use tank systems.
A tank system or secondary containment system from which there has been a leak or spill, or which is unfit-for-use, must be removed from service immediately, and the owner or operator must satisfy the following requirements:
(1) Cessation of use; prevent flow or addition of wastes.
The owner or operator must immediately stop the flow of hazardous waste into the tank system or secondary containment system and inspect the system to determine the cause of the release.
(2) Removal of waste from tank system or secondary containment system.
(i) If the release was from the tank system, the owner or operator must, within 24 hours after detection of the leak or, if the owner or operator demonstrates that that is not possible, at the earliest practicable time remove as much of the waste as is necessary to prevent further release of hazardous waste to the environment and to allow inspection and repair of the tank system to be performed.
(ii) If the release was to a secondary containment system, all released materials must be removed within 24 hours or in as timely a manner as is possible to prevent harm to human health and the environment.
(3) Containment of visible releases to the environment.
The owner or operator must immediately conduct a visual inspection of the release and, based upon that inspection:
(i) prevent further migration of the leak or spill to soils or surface water; and
(ii) remove, and properly dispose of, any visible contamination of the soil or surface water.
(4) Notifications, reports.
(i) Any release to the environment, except as provided in subparagraph (ii) of this paragraph, must be reported to the commissioner within 24 hours of detection. If the release has been reported pursuant to Part 595 of this Title, that report will satisfy this requirement.
Note:
The DEC spill hotline is (800) 457-7362; outside of New York State (518) 457-7362.
(ii) A leak or spill of hazardous waste that is:
(a) less than or equal to a quantity of one pound; and
(b) immediately contained and cleaned-up is exempted from the requirements of this paragraph.
(iii) Within 30 days of detection of a release to the environment, a report containing the following information must be submitted to the commissioner:
(a) likely route of migration of the release;
(b) characteristics of the surrounding soil (soil composition, geology, hydrogeology, climate);
(c) results of any monitoring or sampling conducted in connection with the release, (if available). If sampling or monitoring data relating to the release are not available within 30 days, these data must be submitted to the commissioner as soon as they become available;
(d) proximity to downgradient drinking water, surface water, and population areas; and
(e) description of response actions taken or planned.
(5) Provision of secondary containment repair, or closure.
(i) Unless the owner or operator satisfies the requirements of subparagraphs (ii)-(iv) of this paragraph, the tank system must be closed in accordance with subdivision (h) of this section.
(ii) If the cause of the release was a spill that has not damaged the integrity of the system, the owner/operator may return the system to service as soon as the released waste is removed and repairs, if necessary, are made.
(iii) If the cause of the release was a leak from the primary tank system into the secondary containment system, the system must be repaired prior to returning the tank system to service.
(iv) If the source of the release was a leak to the environment from a component of a tank system without secondary containment, the owner/operator must provide the component of the system from which the leak occurred with secondary containment that satisfies the requirements of subdivision (d) of this section before it can be returned to service, unless the source of the leak is an aboveground portion of a tank system. If the source is an aboveground component that can be inspected visually, the component must be repaired and may be returned to service without secondary containment as long as the requirements of paragraph (6) of this subdivision are satisfied. If a component is replaced to comply with the requirements of this subparagraph, that component must satisfy the requirements for new tank systems or components in subdivisions (c) and (d) of this section. Additionally, if a leak has occurred in any portion of a tank system component that is not readily accessible for visual inspection (e.g., the bottom of an inground or onground tank), the entire component must be provided with secondary containment in accordance with subdivision (d) of this section prior to being returned to use.
(6) Certification of major repairs.
If the owner or operator has repaired a tank system in accordance with paragraph (5) of this subdivision, and the repair has been extensive (e.g., installation of an internal liner; repair of a ruptured primary containment or secondary containment vessel), the tank system must not be returned to service unless the owner/operator has obtained a certification in accordance with section 373-1.4(a)(5)(iv) of this Part by an independent, qualified, professional engineer registered in New York that the repaired system is capable of handling hazardous wastes without release for the expected life of the system. This certification must be submitted to the commissioner within seven days after returning the tank system to use.
Note:
The commissioner may, on the basis of any information received that there is or has been a release of hazardous waste or hazardous constituents into the environment, issue an order under ECL article 71 requiring corrective action or such other response as deemed necessary to protect human health or the environment.
Note:
See section 373-3.2(f)(3) of this Subpart for the requirements necessary to remedy a failure. Also, 40 CFR part 302 requires the owner or operator to notify the National Response Center of a release of any “reportable quantity”.
(h) Closure and post-closure care.
(1) At closure of a tank system the owner or operator must remove or decontaminate all waste residues, contaminated containment system components (liners, etc.), contaminated soils, and structures and equipment contaminated with waste, and manage them as hazardous waste, unless section 371.1(d)(4) of this Title applies. The closure plan, closure activities, cost estimates for closure, and financial responsibility for tank systems must meet all of the requirements specified in sections 373-3.7 and 373-3.8 of this Subpart.
(2) If the owner or operator demonstrates that not all contaminated soils can be practicably removed or decontaminated as required in paragraph (1) of this subdivision, then the owner or operator must close the tank system and perform post-closure care in accordance with the closure and post-closure care requirements that apply to landfills (section 373-3.14[d] of this Subpart). In addition, for the purposes of closure, post-closure, and financial responsibility, such a tank system 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.
(3) If an owner or operator has a tank system which does not have secondary containment that meets the requirements of paragraphs (d)(2)-(6) of this section and which is not exempt from the secondary containment requirements in accordance with paragraph (d)(7) of this section, then:
(i) The closure plan for the tank system must include both a plan for complying with paragraph (1) of this subdivision and a contingency plan for complying with paragraph (2) of this subdivision.
(ii) A contingent post-closure plan for complying with paragraph (2) of this subdivision must be prepared and submitted as part of the permit application.
(iii) The cost estimates calculated for closure and post-closure care must reflect the costs of complying with the contingent closure plan and the contingent post-closure plan, if these costs are greater than the costs of complying with the closure plan prepared for the expected closure under paragraph (1) of this subdivision.
(iv) Financial assurance must be based on the cost estimates in subparagraph (iii) of this paragraph.
(v) For the purposes of the contingent closure and post-closure plans, such a tank system is considered to be a landfill, and the contingent plans must meet all of the closure, post- closure, and financial responsibility requirements for landfills under sections 373-3.7 and 373-3.8 of this Subpart.
(i) Special requirements for ignitable or reactive wastes.
(1) Ignitable or reactive waste must not be placed in a tank system, unless:
(i) the waste is treated, rendered, or mixed before or immediately after placement in the tank system so that:
(a) the resulting waste, mixture, or dissolved material no longer meets the definition of ignitable or reactive waste under section 371.3(b) or (d) of this Title; and
(b) section 373-3.2(h)(2) of this Subpart is complied with; or
(ii) the waste is stored or treated in such a way that it is protected from any material or conditions that may cause the waste to ignite or react; or
(iii) the tank system is used solely for emergencies.
(2) The owner or operator of a facility where ignitable or reactive waste is stored or treated in tanks must comply with the requirements for the maintenance of protective distances between the waste management area and any public ways, streets, alleys, or an adjoining property line that can be built upon as required in Tables 2-1 through 2-6 of the National Fire Protection Association's “Flammable and Combustible Liquids Code” (see section 370.1[e] of this Title).
(j) Special requirements for incompatible wastes.
(1) Incompatible wastes, or incompatible waste and materials, must not be placed in the same tank system, unless section 373-3.2(h)(2) of this Subpart is complied with.
(2) Hazardous waste must not be placed in a tank system that has not been decontaminated and that previously held an incompatible waste or material, unless section 373-3.2(h)(2) of this Subpart is complied with.
(k) Waste analysis and trial tests.
In addition to performing the waste analysis required by section 373-3.2(d) of this Subpart, the owner or operator must, whenever a tank system is to be used to treat chemically or to store a hazardous waste that is substantially different from waste previously treated or stored in that tank system; or treat chemically a hazardous waste with a substantially different process than any previously used in that tank system:
(1) conduct waste analyses and trial treatment or storage tests (e.g., bench-scale or pilot-plant scale tests); or
(2) obtain written, documented information on similar waste under similar operating conditions to show that the proposed treatment or storage will meet the requirements of paragraph (e)(1) of this section.
Note:
Section 373-3.2(d) of this Subpart requires the waste analysis plan to include analyses needed to comply with subdivisions (i) and (j) of this section. Section 373-3.5 (c) of this Subpart requires the owner or operator to place the results from each waste analysis and trial test, or the documented information, in the operating record of the facility.
(l) Special requirements for generators of between 100 and 1,000 kg/mo that accumulate hazardous waste in tanks.
(1) The requirements of this subdivision apply to small quantity generators of more than 100 kg but less than 1,000 kg of hazardous waste in a calendar month, that accumulate hazardous waste in tanks for less than 180 days (or 270 days if the generator must ship the waste greater than 200 miles), and do not accumulate over 6,000 kg onsite at any time.
(2) Generators of between 100 and 1,000 kg/mo hazardous waste must comply with the following general operating requirements:
(i) Treatment or storage of hazardous waste in tanks must comply with section 373-3.2(h)(2) of this Subpart.
(ii) Hazardous wastes or treatment reagents must not be placed in a tank if they could cause the tank or its inner liner to rupture, leak, corrode, or otherwise fail before the end of its intended life.
(iii) Uncovered tanks must be operated to ensure at least 60 centimeters (two feet) of freeboard, unless the tank is equipped with a containment structure (e.g., dike or trench), a drainage control system, or a diversion structure (e.g., standby tank) with a capacity that equals or exceeds the volume of the top 60 centimeters (two feet) of the tank.
(iv) Where hazardous waste is continuously fed into a tank, the tank must be equipped with a means to stop this inflow (e.g., waste feed cutoff system or bypass system to a standby tank).
Note:
These systems are intended to be used in the event of a leak or overflow from the tank due to a system failure (e.g., a malfunction in the treatment process, a crack in the tank, etc).
(3) Except as noted in paragraph (4) of this subdivision, generators between 100 and 1,000 kg/mo accumulating hazardous waste in tanks must inspect, where present:
(i) discharge control equipment (e.g., waste feed cutoff systems, bypass systems, and drainage systems) at least once each operating day, to ensure that it is in good working order;
(ii) data gathered from monitoring equipment (e.g., pressure and temperature gauges) at least once each operating day to ensure that the tank is being operated according to its design;
(iii) the level of waste in the tank at least once each operating day to ensure compliance with subparagraph (2)(iii) of this subdivision;
(iv) the construction materials of the tank at least weekly to detect corrosion or leaking of fixtures or seams; and;
(v) the construction materials of, and the area immediately surrounding, discharge confinement structures (e.g., dikes) at least weekly to detect erosion or obvious signs of leakage (e.g., wet spots or dead vegetation).
Note:
As required by section 373-3.2(f)(3) of this Subpart, the owner or operator must remedy any deterioration or malfunction the owner or operator finds.
(4) Generators who accumulate between 100 and 1,000 kg/mo of hazardous waste in tanks or tank systems that have full secondary containment and that either use leak detection equipment to alert facility personnel to leaks, or implement other established workplace practices to ensure leaks are promptly identified and must inspect at least weekly, where applicable, the areas identified in subparagraphs (3)(i) and (v) of this subdivision. Use of the alternate inspection schedule must be documented in the facility's operating record. This documentation must include a description of the established workplace practices at the facility.
(5) Generators of between 100 and 1,000 kg/mo accumulating hazardous waste in tanks must, upon closure of the facility, remove all hazardous waste from tanks, discharge control equipment and discharge confinement structures.
Note:
At closure, as throughout the operating periods, unless the owner or operator can demonstrate, in accordance with section 371.1(d)(3) or (4) of this Title, that any solid waste removed from the tank is not a hazardous waste, the owner or operator becomes a generator of hazardous waste and must manage it in accordance with all applicable requirements of Parts 370 through 374 and 376 of this Title.
(6) Generators of between 100 and 1,000 kg/mo must comply with the following special requirements for ignitable or reactive waste:
(i) Ignitable or reactive waste must not be placed in a tank, unless:
(a) the waste is treated, rendered, or mixed before or immediately after placement in a tank so that:
(1) the resulting waste, mixture, or dissolution of material no longer meets the definition of ignitable or reactive waste under section 371.3(b) or (d) of this Title; and
(2) section 373-3.2(h)(2) of this Subpart is complied with; or
(b) the waste is stored or treated in such a way that it is protected from any material or conditions that may cause the waste to ignite or react; or
(c) the tank is used solely for emergencies.
(ii) The owner or operator of a facility which treats or stores ignitable or reactive waste in covered tanks must comply with the buffer zone requirements for tanks contained in Tables 2-1 through 2-6 of the National Fire Protection Association's "Flammable and Combustible Liquids Code" (see section 370.1[e] of this Title).
(7) Generators of between 100 and 1,000 kg/mo must comply with the following special requirements for incompatible wastes.
(i) Incompatible wastes, or incompatible wastes and materials, (see Appendix 29 of this Title for examples) must not be placed in the same tank, unless section 373-3.2(h)(2) of this Subpart is complied with.
(ii) Hazardous waste must not be placed in an unwashed tank which previously held an incompatible waste or material, unless section 373-3.2(h)(2) of this Subpart is complied with.
(m) Air emissions standards.
The owner or operator shall manage all hazardous waste placed in a tank in accordance with the applicable requirements of sections 373-3.27, 373-3.28 and 373-3.29 of this Subpart.
