The treatment and disposal of hazardous waste military munitions are subject to the applicable permitting, procedural, and technical standards in Parts 260 through 268 and 122.
(j) The requirements of Subparts B, C, and D of this part and §264.101 do not apply to remediation waste management sites. (However, some remediation waste management sites may be a part of a facility that is subject to a traditional hazardous waste permit because the facility is also treating, storing or disposing of hazardous wastes that are not remediation wastes. In these cases, Subparts B, C, and D of this part, and §264.101 do apply to the facility subject to the traditional hazardous waste permit.) Instead of the requirements of Subparts B, C, and D of this part, owners or operators of remediation waste management sites must:
(1) Obtain an EPA identification number by applying to the Secretary using EPA Form 8700-12;
(2) Obtain a detailed chemical and physical analysis of a representative sample of the hazardous remediation wastes to be managed at the site. At a minimum, the analysis must contain all of the information which must be known to treat, store or dispose of the waste according to this part and Part 268 of these regulations, and must be kept accurate and up to date;
(3) Prevent people who are unaware of the danger from entering, and minimize the possibility for unauthorized people or livestock to enter onto the active portion of the remediation waste management site, unless the owner or operator can demonstrate to the Secretary that:
(i) Physical contact with the waste, structures, or equipment within the active portion of the remediation waste management site will not injure people or livestock who may enter the active portion of the remediation waste management site; and
(ii) Disturbance of the waste or equipment by people or livestock who enter onto the active portion of the remediation waste management site, will not cause a violation of the requirements of this part;
(4) Inspect the remediation waste management site for malfunctions, deterioration, operator errors, and discharges that may be causing, or may lead to, a release of hazardous waste constituents to the environment, or a threat to human health. The owner or operator must conduct these inspections often enough to identify problems in time to correct them before they harm human health or the environment, and must remedy the problem before it leads to a human health or environmental hazard. Where a hazard is imminent or has already occurred, the owner/ operator must take remedial action immediately;
(5) Provide personnel with classroom or on-the-job training on how to perform their duties in a way that ensures the remediation waste management site complies with the requirements of this part, and on how to respond effectively to emergencies;
(6) Take precautions to prevent accidental ignition or reaction of ignitable or reactive waste, and prevent threats to human health and the environment from ignitable, reactive and incompatible waste;
(7) For remediation waste management sites subject to regulation under Subparts I through O and Subpart X of this part, the owner/operator must design, construct, operate, and maintain a unit within a 100-year floodplain to prevent washout of any hazardous waste by a 100-year flood, unless the owner/operator can meet the demonstration of §264.18(b);
(8) Not place any non-containerized or bulk liquid hazardous waste in any salt dome formation, salt bed formation, underground mine or cave;
(9) Develop and maintain a construction quality assurance program for all surface impoundments, waste piles and landfill units that are required to comply with §§ 264.221(c) and (d), 264.251(c) and (d), and 264.301(c) and (d) at the remediation waste management site, according to the requirements of §264.19;
(10) Develop and maintain procedures to prevent accidents and a contingency and emergency plan to control accidents that occur. These procedures must address proper design, construction, maintenance, and operation of remediation waste management units at the site. The goal of the plan must be to minimize the possibility of, and the hazards from a fire, explosion, or any unplanned sudden or non-sudden release of hazardous waste or hazardous waste constituents to air, soil, or surface water that could threaten human health or the environment. The plan must explain specifically how to treat, store and dispose of the hazardous remediation waste in question, and must be implemented immediately whenever a fire, explosion, or release of hazardous waste or hazardous waste constituents which could threaten human health or the environment;
(11) Designate at least one employee, either on the facility premises or on call (that is, available to respond to an emergency by reaching the facility quickly), to coordinate all emergency response measures. This emergency coordinator must be thoroughly familiar with all aspects of the facility's contingency plan, all operations and activities at the facility, the location and characteristics of waste handled, the location of all records within the facility, and the facility layout. In addition, this person must have the authority to commit the resources needed to carry out the contingency plan;
(12) Develop, maintain and implement a plan to meet the requirements in paragraphs (j)(2) through (j)(6) and (j)(9) through (j)(10) of this section; and
(13) Maintain records documenting compliance with paragraphs (j)(1) through (j)(12) of this section.

Section 264.3 Relationship to interim status standards.
A facility owner or operator who has fully complied with the requirements for interim status - as defined in 7 Del.C., §6307(g) and regulations under §122.70 of these regulations - must comply with the regulations specified in Part 265 of these regulations in lieu of the regulations in this part, until final administrative disposition of his permit application is made, except as provided under Part 264, Subpart S.
[Comment: As stated in 7 Del.C., §6307(g), after the effective date of regulations under that §, i.e., Parts 122 and 124 of these regulations, the treatment, storage, or disposal of hazardous waste is prohibited except in accordance with a permit. Seven Del.C., §6307(g) provides for the continued operation of an existing facility which meets certain conditions until final administrative disposition of the owner's or operator's permit application is made.]
(Amended August 1, 1995, January 1, 1999)
Section 264.4 Imminent hazard action.
Notwithstanding any other provisions of these regulations, enforcement actions may be brought pursuant to 7 Del.C., §6308.
(a)The regulations in this subpart apply to owners and operators of all hazardous waste facilities, except as provided in §264.1 and in paragraph (b) of this section.
(b)§264.18(b) is applicable only to facilities subject to regulation under Subparts I through O of this part and Subpart X of this part.
(a) Every facility owner or operator must apply to the Secretary for an EPA identification number in accordance with the State notification procedures.
(b) A facility must submit a subsequent State of Delaware Notification of Regulated Waste Activity Form (8700-12) whenever there is a change in name, mailing address, contact person, contact address, telephone number, ownership, type of regulated waste activity, or changes in the description of regulated wastes managed or permanently ceases the regulated waste activity. This subsequent notification must be submitted to the Secretary no less than 10 days prior to implementation of the change(s).
(a) (1) The owner or operator of a facility that has arranged to receive hazardous waste from a foreign source must notify the Regional Administrator in writing at least four weeks in advance of the date the waste is expected to arrive at the facility. Notice of subsequent shipments of the same waste from the same foreign source is not required.
(2) The owner or operator of a recovery facility that has arranged to receive hazardous waste subject to Part 262, Subpart H must provide a copy of the tracking document bearing all required signatures to the notifier, to the Office of Enforcement and Compliance Assurance, Office of Compliance, Enforcement Planning, Targeting and Data Division (2222A), Environmental Protection Agency, 401 M St., SW, Washington, DC 20460; and to the competent authorities of all other concerned countries within three working days of receipt of the shipment. The original of the signed tracking document must be maintained at the facility for at least three years.
(3) A copy of the signed tracking document must also be submitted to the DNREC Secretary.
(b) The owner or operator of a facility that receives hazardous waste from an off-site source (except where the owner or operator is also the generator) must inform the generator in writing that he has the appropriate permit(s) for, and will accept, the waste the generator is shipping. The owner or operator must keep a copy of this written notice as part of the operating record.
(c) Before transferring ownership or operation of a facility during its operating life, or of a disposal facility during the post-closure care period, the owner or operator must notify the new owner or operator in writing of the requirements of this part and Part 122 of these regulations.
[Comment: An owner's or operator's failure to notify the new owner or operator of the requirements of this part in no way relieves the new owner or operator of his obligation to comply with all applicable requirements.]
(Amended January 1, 1999)
(a) (1) Before an owner or operator treats, stores, or disposes of any hazardous wastes, he must obtain a detailed chemical and physical analysis of a representative sample of the wastes. At a minimum, the analysis must contain all the information which must be known to treat, store, or dispose of the waste in accordance with this part and Part 268 of these regulations.
(2) The analysis may include data developed under Part 261 of these regulations, and existing published or documented data on the hazardous waste or on hazardous waste generated from similar processes.
[Comment: For example, the facility's records of analyses performed on the waste before the effective date of these regulations, or studies conducted on hazardous waste generated from process similar to that which generated the waste to be managed at the facility, may be included in the data base required to comply with paragraph (a)(1) of this section. The owner or operator of an off-site facility may arrange for the generator of the hazardous waste to supply part of the information required by paragraph (a)(1) of this section except as otherwise specified in §268.7(b) and (c) of these regulations. If the generator does not supply the information, and the owner or operator chooses to accept a hazardous waste, the owner or operator is responsible for obtaining the information required to comply with this section.]
(3) The analysis must be repeated as necessary to ensure that it is accurate and up to date. At a minimum, the analysis must be repeated:
(i) When the owner or operator is notified, or has reason to believe, that the process or operation generating the hazardous waste has changed; and
(ii) For off-site facilities, when the results of the inspection required in paragraph (a)(4) of this section indicate that the hazardous waste received at the facility does not match the waste designated on the accompanying manifest or shipping paper.
(4) The owner or operator of an off-site facility must inspect and, if necessary, analyze each hazardous waste movement received at the facility to determine whether it matches the identity of the waste specified on the accompanying manifest or shipping paper.
(b) The owner or operator must develop and follow a written waste analysis plan which describes the procedures which he will carry out to comply with paragraph (a) of this section. He must keep this plan at the facility. At a minimum, the plan must specify:
(1) The parameters for which each hazardous waste will be analyzed and the rationale for the selection of these parameters (i.e., how analysis for these parameters will provide sufficient information on the waste's properties to comply with paragraph (a) of this section);
(2) The test methods which will be used to test for these parameters;
(3) The sampling method which will be used to obtain a representative sample of the waste to be analyzed. A representative sample may be obtained using either:
(i) One of the sampling methods described in Appendix I of Part 261 of these regulations; or
(ii) An equivalent sampling method.
[Comment: See Part 260 Subpart C of these regulations for related discussion.]
(4) The frequency with which the initial analysis of the waste will be reviewed or repeated to ensure that the analysis is accurate and up-to-date; and
(5) For off-site facilities, the waste analyses that hazardous waste generators have agreed to supply.
(6) Where applicable, the methods that will be used to meet the additional waste analysis requirements for specific waste management methods as specified in §§264.17, 264.314, 264.341, 264.1034(d), 264.1063(d), 264.1083, and 268.7 of these regulations.
(7) For surface impoundments exempted from land disposal restrictions under §268.4(a), the procedures and schedules for:
(i) The sampling of impoundment contents;
(ii) The analysis of test data; and,
(iii) The annual removal of residues which are not delisted under §260.22 of these regulations or which exhibit a characteristic of hazardous waste and either:
(A) Do not meet applicable treatment standards of Part 268, Subpart D; or
(B) Where no treatment standards have been established: (1) Such residues are prohibited from land disposal under §268.32 or 7 Del.C., Chapter 63; or
(2) Such residues are prohibited from land disposal under §268.33(f).
(8) For owners and operators seeking an exemption to their air emission standards of Subpart CC in accordance with §264.1082.
(i) If direct measurement is used for the waste determination, the procedures and schedules for waste sampling and analysis, and the results of the analysis of test data to verify the exemption.
(ii) If knowledge of the waste is used for the waste determination, any information prepared by the facility owner or operator or by the generator of the hazardous waste, if the waste is received from off-site, that is used as the basis for knowledge of the waste.
(c) For off-site facilities, the waste analysis plan required in paragraph (b) of this section must also specify the procedures which will be used to inspect and, if necessary, analyze each movement of hazardous waste received at the facility to ensure that it matches the identity of the waste designated on the accompanying manifest or shipping paper. At a minimum, the plan must describe:
(1) The procedures which will be used to determine the identity of each movement of waste managed at the facility; and
(2) The sampling method which will be used to obtain a representative sample of the waste to be identified, if the identification method includes sampling.
[Comment: Part 122, Subpart B, of these regulations requires that the waste analysis plan be submitted with Part B of the permit application.]
(3) The procedures that the owner or operator of an off-site landfill receiving containerized hazardous waste will use to determine whether a hazardous waste generator or treater has added a biodegradable sorbent to the waste in the container.
(Amended June 19, 1992, August 1, 1995, January 1, 1999)
(a) The owner or operator must prevent the unknowing entry, and minimize the possibility for the unauthorized entry, of persons or livestock onto the active portion of this facility, unless he can demonstrate to the Secretary that:
(1) Physical contact with the waste, structures, or equipment within the active portion of the facility will not injure unknowing or unauthorized persons or livestock which may enter the active portion of a facility; and
(2) Disturbance of the waste or equipment, by the unknowing or unauthorized entry of persons or livestock onto the active portion of a facility, will not cause a violation of the requirements of this part.
[Comment: Part 122, Subpart B, of these regulations requires that an owner or operator who wishes to make the demonstration referred to above must do so with Part B of the permit application.]
(b) Unless the owner or operator has made a successful demonstration under paragraphs (a)(1) and (a)(2) of this section, facility must have:
(1) A 24-hour surveillance system (e.g., television monitoring or surveillance by guards or facility personnel) which continuously monitors and controls entry onto the active portion of the facility; or
(2) (i) An artificial or natural barrier (e.g., a fence in good repair or a fence combined with a cliff), which completely surrounds the active portion of the facility; and
(ii) A means to control entry, at all times, through the gates or other entrances to the active portion of the facility (e.g., an attendant, television monitors, locked entrance, or controlled roadway access to the facility).
[Comment: The requirements of paragraph (b) of this section are satisfied if the facility or plant within which the active portion is located itself has a surveillance system, or a barrier and a means to control entry, which complies with the requirements of paragraph (b)(1) or (b)(2) of this section.]
(c) Unless the owner or operator has made a successful demonstration under paragraphs (a)(1) and (a)(2) of this section, a sign with legend, "Danger - Unauthorized Personnel Keep Out", must be posted at each entrance to the active portion of a facility, and at other locations, in sufficient numbers to be seen from any approach to this active portion. The legend must be written in English and in any other language predominant in the area surrounding the facility (e.g., facilities in counties bordering the Canadian province of Quebec must post signs in French; facilities in counties bordering Mexico must post signs in Spanish), and must be legible from a distance of at least 25 feet. Existing signs with a legend other than "Danger - Unauthorized Personnel Keep Out" may be used if the legend on the sign indicates that only authorized personnel are allowed to enter the active portion, and that entry onto the active portion can be dangerous.
[Comment: See §264.117(b) for discussion of security requirements at disposal facilities during the post-closure care period.]
(a) The owner or operator must inspect his facility for malfunctions and deterioration, operator errors, and discharges which may be causing - or may lead to - (1) release of hazardous waste constituents to the environment or (2) a threat to human health. The owner or operator must conduct these inspections often enough to identify problems in time to correct them before they harm human health or the environment.
(b) (1) The owner or operator must develop and follow a written schedule for inspecting monitoring equipment, safety, and emergency equipment, security devices, and operating and structural equipment (such as dikes and sump pumps) that are important to preventing, detecting, or responding to environmental or human health hazards.
(2) He must keep this schedule at the facility.
(3) The schedule must identify the types of problems (e.g., malfunctions or deterioration) which are to be looked for during the inspection (e.g., inoperative sump pump, leaking fitting, eroding dike, etc.).
(4) The frequency of inspection may vary for the items on the schedule. However, the frequency should be based on the rate of deterioration of the equipment and the probability of an environmental or human health incident if the deterioration, malfunction, or any operator error goes undetected between inspections. Areas subject to spills, such as loading and unloading areas, must be inspected daily when in use. At a minimum, the inspection schedule must include the items and frequencies called for in §§ 264.174, 264.193, 264.195, 264.226, 264.254, 264.278, 264.303, 264.347, 264.602, 264.1033, 264.1052, 264.1053, 264.1058, and 264.1083 through 264.1089 of this part, where applicable.
[Comment: Part 122, Subpart B, of these regulations requires the inspection schedule to be submitted with Part B of the permit application. DNREC will evaluate the schedule along with the rest of the application to ensure that it adequately protects human health and the environment. As part of this review, DNREC may modify or amend the schedule as may be necessary.]
(c) The owner or operator must remedy any deterioration or malfunction of equipment or structures which the inspection reveals on a schedule which ensures that the problem does not lead to an environmental or human health hazard. Where a hazard is imminent or has already occurred, remedial action must be taken immediately.
(d) The owner or operator must record inspections in an inspection log or summary. He must keep these records for at least three years from the date of inspection. At a minimum, these records must include the date and time of the inspection, the name of the inspector, a notation of the observations made, and the date and nature of any repairs or other remedial actions.
(Amended August 29, 1988; August 10, 1990, August 1, 1995, January 1, 1999, August 23, 1999)
(a) (1) Facility personnel must successfully complete a program of classroom instruction or on-the-job training that teaches them to perform their duties in a way that ensures the facility's compliance with the requirements of this part. The owner or operator must ensure that this program includes all the elements described in the document required under paragraph (d)(3) of this section.
[Comment: Part 122, Subpart B, of these regulations requires that owners and operators submit with Part B of the permit application, an outline of the training program used (or to be used) at the facility and a brief description of how the training program is designed to meet actual job tasks.]
(2) This program must be directed by a person trained in hazardous waste management procedures, and must include instruction which teaches facility personnel hazardous waste management procedures (including contingency plan implementation) relevant to the positions in which they are employed.
(3) At a minimum, the training program must be designed to ensure that facility personnel are able to respond effectively to emergency procedures, emergency equipment, and emergency systems, including where applicable:
(i) Procedures for using, inspecting, repairing, and replacing facility emergency and monitoring equipment;
(ii) Key parameters for automatic waste feed cut-off systems;
(iii) Communications or alarm systems;
(iv) Response to fires or explosions;
(v) Response to groundwater contamination incidents; and
(vi) Shutdown of operations.
(b) Facility personnel must successfully complete the program required in paragraph (a) of this section within six months after the effective date of these regulations or six months after the date of their employment or assignment to a facility, or to a new position at a facility, whichever is later. Employees hired after the effective date of these regulations must not work in unsupervised positions until they have completed the training requirements of paragraph (a) of this section.
(c) Facility personnel must take part in an annual review of the initial training required in paragraph (a) of this section.
(d) The owner or operator must maintain the following documents and records at the facility:
(1) The job title for each position at the facility related to hazardous waste management, and the name of the employee filling each job;
(2) A written job description for each position listed under paragraph (d)(1) of this section. This description may be consistent in its degree of specificity with descriptions for other similar positions in the same company location or bargaining unit, but must include the requisite skill, education, or other qualifications, and duties of employees assigned to each position;
(3) A written description of the type and amount of both introductory and continuing training that will be given to each person filling a position listed under paragraph (d)(1) of this section;
(4) Records that document that the training or job experience required under paragraphs (a), (b), and (c) of this section has been given to, and completed by, facility personnel.
(e) Training records on current personnel must be kept until closure of the facility; training records on former employees must be kept for at least three years from the date the employee last worked at the facility. Personnel training records may accompany personnel transferred within the same company.
(a) The owner or operator must take precautions to prevent accidental ignition or reaction of ignitable or reactive waste. This waste must be separated and protected from sources of ignition or reaction including but not limited to: open flames, smoking, cutting and welding, hot surfaces, frictional heat, sparks (static, electrical, or mechanical), spontaneous ignition (e.g., from heat-producing chemical reactions), and radiant heat. While ignitable or reactive waste is being handled, the owner or operator must confine smoking and open flame to specially designated locations. "No Smoking" signs must be conspicuously placed wherever there is a hazard from ignitable or reactive waste.
(b) Where specifically required by other sections of the part, the owner or operator of a facility that treats, stores, or disposes ignitable or reactive waste, or mixes incompatible waste or incompatible wastes and other materials, must take precautions to prevent reactions which:
(1) Generate extreme heat or pressure, fire or explosions, or violent reactions;
(2) Produce uncontrolled toxic mists, fumes, dusts, or gases in sufficient quantities to threaten human health or the environment;
(3) Produce uncontrolled flammable fumes or gases in sufficient quantities to pose a risk of fire or explosions;
(4) Damage the structural integrity of the device or facility;
(5) Through other like means threaten human health or the environment.
(c) When required to comply with paragraph (a) or (b) of this section, the owner or operator must document that compliance. This documentation may be based on references to published scientific or engineering literature, data from trial tests (e.g., bench scale or pilot scale tests), waste analyses (as specified in §264.13), or the result of the treatment of similar wastes by similar treatment processes and under similar operating conditions.
(a) Seismic considerations.
(1) Portions of new facilities where treatment, storage, or disposal of hazardous waste will be conducted must not be located within 61 meters (200 feet) of a fault which has had displacement in Holocene time.
(2) As used in paragraph (a)(1) of this section:
(i) Fault means a fracture along which rocks on one side have been displaced with respect to those on the other side.
(ii) Displacement means the relative movement of any two sides of a fault measured in any direction.
(iii) Holocene means the most recent epoch of the Quaternary period, extending from the end of the Pleistocene to the present.
[Comment: Procedures for demonstrating compliance with this standard in Part B of the permit application are specified in §122.14(b)(11). Facilities which are located in political jurisdictions other than those listed in Appendix VI of this part, are assumed to be in compliance with this requirement.]
(b) Floodplains.
(1) A facility located in a 100-year floodplain must be designed, constructed, operated, and maintained to prevent washout of any hazardous waste by a 100-year flood unless the owner or operator can demonstrate to the Secretary's satisfaction that:
(i) Procedures are in effect which will cause the waste to be removed safely, before flood waters can reach the facility, to a location where the wastes will not be vulnerable to flood waters; or
(ii) For existing surface impoundments, waste piles, land treatment units, landfills, and miscellaneous units, no adverse effects on human health or the environment will result if washout occurs, considering:
(A) The volume and physical and chemical characteristics of the waste in the facility;
(B) The concentration of hazardous constituents that would potentially affect surface waters as a result of washout;
(C) The impact of such concentrations on the current or potential uses of and water quality standards established for the affected surface waters; and
(D) The impact of hazardous constituents on the sediments of affected surface waters or the soils of the 100-year floodplain that could result from washout.
[Comment: The location where wastes are moved must be a facility which is either permitted by DNREC under Part 122 of these regulations, authorized to manage hazardous waste by a State with a hazardous waste management program authorized under 40 CFR, Part 123, or in interim status under Parts 122 and 265 of these regulations.]
(2) As used in paragraph (b)(1) of this section:
(i) 100-year floodplain means any land area which is subject to a one percent or greater chance of flooding in any given year from any source.
(ii) Washout means the movement of hazardous waste from the active portion of the facility as a result of flooding.
(iii) 100-year flood means a flood that has a one percent chance of being equaled or exceeded in any given year.
[Comment: Requirements pertaining to other laws which affect the location and permitting of facilities are found in §122.12 of these regulations. For details relative to these laws, see DNREC's manual for SEA (special environmental area) requirements for hazardous waste facility permits. Though DNREC is responsible for complying with these requirements, applicants are advised to consider them in planning the location of a facility to help prevent subsequent project delays. Also, refer to the Delaware Regulations Governing the Location of Hazardous Waste Storage, Treatment and Disposal Facilities for further requirements which affect the location and permitting of facilities. Applicants are responsible for complying with these requirements.]
(c) Salt dome formations, salt bed formations, underground mines and caves. The placement of any non-containerized or bulk liquid hazardous waste in any salt dome formation, salt bed formation, underground mine or cave is prohibited.
[Note: The definition of a wetland can be found in the DNREC Wetland Regulations of 1976 which were adopted under 7 Del.C., §6607.]
