Current through June 24, 2024
(1) VERY SMALL QUANTITY GENERATOR. A very
				  small quantity generator may maintain its existing generator category for
				  hazardous waste generated during an episodic event provided that the generator
				  complies with all of the following:
(a) The
				  very small quantity generator is limited to one episodic event per calendar
				  year, unless a petition is granted under s. NR 662.233.
(b) The very small quantity generator shall
				  notify the department no later than 30 calendar days prior to initiating a
				  planned episodic event using EPA Form 8700-12. In the event of an unplanned
				  episodic event, the generator shall notify the department within 72 hours of
				  the unplanned event via phone, email, or fax and subsequently submit EPA Form
				  8700-12. The generator's notification shall include the start date and end date
				  of the episodic event, the reason for the episodic event, types and estimated
				  quantities of hazardous waste expected to be generated as a result of the
				  episodic event, and shall identify a facility contact and emergency coordinator
				  with 24-hour telephone access to discuss the notification submittal or respond
				  to an emergency in compliance with s. NR 662.016(2) (i) 1.
(c) The very small quantity generator shall
				  have an EPA identification number or obtain an EPA identification number using
				  EPA Form 8700-12.
(d) A very small
				  quantity generator is prohibited from accumulating hazardous waste generated
				  from an episodic event on drip pads and in containment buildings. When
				  accumulating hazardous waste in containers and tanks the following conditions
				  apply:
1. A very small quantity generator
				  accumulating in containers shall mark or label its containers with all of the
				  following:
a. The words "Episodic Hazardous
				  Waste."
b. An indication of the
				  hazards of the contents. Acceptable indications of hazardous contents include
				  the following: applicable hazardous waste characteristic or characteristics,
				  such as ignitable, corrosive, reactive, or toxic; hazard communication
				  consistent with the department of transportation requirements on labeling or
				  placarding, incorporated into s.
				  Trans
				  326.01(3); a hazard statement or
				  pictogram consistent with the Occupational Safety and Health Administration
				  Hazard Communication Standard, incorporated into s.
				  SPS
				  332.50; or a chemical hazard label consistent with the
				  National Fire Protection Association 704 label, incorporated into s.
				  SPS 314.001(1)
				  (a)."
c. The date the episodic event began, clearly
				  visible for inspection on each container.
2. A very small quantity generator
				  accumulating episodic hazardous waste in tanks shall do all of the following:
a. Mark or label the tanks with the words
				  "Episodic Hazardous Waste."
b. Mark
				  or label the tanks with an indication of the hazards of the contents.
				  Acceptable indications of hazardous contents include the following: applicable
				  hazardous waste characteristic or characteristics, such as ignitable,
				  corrosive, reactive, or toxic; hazard communication consistent with the
				  department of transportation requirements on labeling or placarding,
				  incorporated into s.
				  Trans
				  326.01(3); a hazard statement or
				  pictogram consistent with the Occupational Safety and Health Administration
				  Hazard Communication Standard, incorporated into s.
				  SPS
				  332.50; or a chemical hazard label consistent with the
				  National Fire Protection Association 704 label, incorporated into s.
				  SPS 314.001(1)
				  (a).
c. Use inventory logs, monitoring equipment
				  or other records to identify the date upon which each episodic event
				  begins.
d. Keep inventory logs or
				  records with the information specified in subd. c. on-site and available for
				  inspection for at least 3 years from the end date of the episodic
				  event.
3. Hazardous waste
				  shall be managed in a manner that minimizes the possibility of a fire,
				  explosion, or release of hazardous waste or hazardous waste constituents to the
				  air, soil, or water, including all of the following conditions:
a. Containers shall be in good condition and
				  compatible with the hazardous waste being accumulated therein. Containers shall
				  be kept closed except to add or remove waste.
b. Tanks shall be in good condition and
				  compatible with the hazardous waste accumulated therein. Tanks shall have
				  procedures in place to prevent overflow. Tanks shall be inspected at least once
				  each operating day to ensure all applicable discharge control equipment, such
				  as waste feed cutoff systems, bypass systems, and drainage systems are in good
				  working order and to ensure the tank is operated according to its design by
				  reviewing the data gathered from monitoring equipment such as pressure and
				  temperature gauges from the inspection.
Note:
Examples of preventing a tank overflow
					 include high level alarms, an automatic waste feed cutoff system, or a bypass
					 system to a standby tank when hazardous waste is continuously fed into the
					 tank.
(e) The very small quantity generator shall
				  comply with the hazardous waste manifest provisions of subch. B when it sends
				  its episodic event hazardous waste off-site to a designated facility, as
				  defined in s.
				  NR
				  660.10(21).
(f) The very small quantity generator shall
				  manifest and send its hazardous waste generated from the episodic event to a
				  designated facility, as defined in s.
				  NR
				  660.10(21), within 60 days of the
				  start of the event.
(g) A very
				  small quantity generator shall maintain all of the following records for 3
				  years from the end date of the episodic event:
1. Beginning and end dates of the episodic
				  event.
2. A description of the
				  episodic event.
3. A description of
				  the types and quantities of hazardous wastes generated during the
				  event.
4. A description of how the
				  hazardous waste was managed as well as the name of the RCRA-designated facility
				  that received the hazardous waste.
5. The name of the hazardous waste
				  transporter.
6. An approval letter
				  from the department if the generator petitioned to conduct one additional
				  episodic event per calendar year.
