South Carolina Code of Regulations › Chapter 61 - DEPARTMENT OF HEALTH AND ENVIRONMENTAL CONTROL › Subchapter 61-79 - Hazardous Waste Management Regulations › Part 61-79.265 - INTERIM STATUS STANDARDS FOR OWNERS AND OPERATORS OF HAZARDOUS WASTE TREATMENT, STORAGE, AND DISPOSAL FACILITIES › Subpart K - SURFACE IMPOUNDMENTS › Section 61-79.265.K.222 - Action leakage rate

Current through Register Vol. 48, No. 6, June 28, 2024
(a) The
				  owner or operator of surface impoundment units subject to 265.221(a) must
				  submit a proposed action leakage rate to the Department when submitting the
				  notice required under 265.221(b). Within 60 days of receipt of the
				  notification, the Department will: Establish an action leakage rate, either as
				  proposed by the owner or operator or modified using the criteria in this
				  section; or extend the review period for up to 30 days. If no action is taken
				  by the Department before the original 60 or extended 90 day review periods, the
				  action leakage rate will be approved as proposed by the owner or
				  operator.
(b) The Department shall
				  approve an action leakage rate for surface impoundment units subject to
				  265.221(a). The action leakage rate is the maximum design flow rate that the
				  leak detection system (LDS) can remove without the fluid head on the bottom
				  liner exceeding 1 foot. The action leakage rate must include an adequate safety
				  margin to allow for uncertainties in the design (e.g., slope, hydraulic
				  conductivity, thickness of drainage material), construction, operation, and
				  location of the LDS, waste and leachate characteristics, likelihood and amounts
				  of other sources of liquids in the LDS, and proposed response actions (e.g.,
				  the action leakage rate must consider decreases in the flow capacity of the
				  system over time resulting from siltation and clogging, rib layover and creep
				  of synthetic components of the system, overburden pressures, etc.).
(c) To determine if the action leakage rate
				  has been exceeded, the owner or operator must convert the weekly or monthly
				  flow rate from the monitoring data obtained under 265.226(b), to an average
				  daily flow rate (gallons per acre per day) for each sump. Unless the Department
				  approves a different calculation, the average daily flow rate for each sump
				  must be calculated weekly during the active life and closure period, and if the
				  unit closes in accordance with 265.228(a)(2), monthly during the post-closure
				  care period when monthly monitoring is required under 265.226(b).

				  develop and keep on site until closure of the facility a response action plan.
				  The response action plan must set forth the actions to be taken if the action
				  leakage rate has been exceeded. At a minimum, the response action plan must
				  describe the actions specified in paragraph (b) of this section.
(b) If the flow rate into the leak detection
				  system exceeds the action leakage rate for any sump, the owner or operator
				  must:
(1) Notify the Department in writing of
				  the exceedance within 7 days of the determination;
(2) Submit a preliminary written assessment
				  to the Department within 14 days of the determination, as to the amount of
				  liquids, likely sources of liquids, possible location, size, and cause of any
				  leaks, and short-term actions taken and planned;
(3) Determine to the extent practicable the
				  location, size, and cause of any leak;
(4) Determine whether waste receipt should
				  cease or be curtailed, whether any waste should be removed from the unit for
				  inspection, repairs, or controls, and whether or not the unit should be
				  closed;
(5) Determine any other
				  short-term and longer-term actions to be taken to mitigate or stop any leaks;
				  and
(6) Within 30 days after the
				  notification that the action leakage rate has been exceeded, submit to the
				  Department the results of the analyses specified in paragraphs (b)(3), (4), and
				  (5) of this section, the results of actions taken, and actions planned. Monthly
				  thereafter, as long as the flow rate in the leak detection system exceeds the
				  action leakage rate, the owner or operator must submit to the Department a
				  report summarizing the results of any remedial actions taken and actions
				  planned.

(a) The
				  owner or operator of waste pile units subject to 265.254 must submit a proposed
				  action leakage rate to the Department when submitting the notice required under
				  265.254. Within 60 days of receipt of the notification, the Department will:
				  Establish an action leakage rate, either as proposed by the owner or operator
				  or modified using the criteria in this section; or extend the review period for
				  up to 30 days. If no action is taken by the Department before the original 60
				  or extended 90 day review periods, the action leakage rate will be approved as
				  proposed by the owner or operator.
(b) The Department shall approve an action
				  leakage rate for waste pile units subject to section 265.254. The action
				  leakage rate is the maximum design flow rate that the leak detection system
				  (LDS) can remove without the fluid head on the bottom liner exceeding one (1)
				  foot. The action leakage rate must include an adequate safety margin to allow
				  for uncertainties in the design (e.g., slope, hydraulic conductivity, thickness
				  of drainage material), construction, operation, and location of the LDS, waste
				  and leachate characteristics, likelihood and amounts of other sources of
				  liquids in the LDS, and proposed response actions (e.g., the action leakage
				  rate must consider decreases in the flow capacity of the system over time
				  resulting from siltation and clogging, rib layover and creep of synthetic
				  components of the system, overburden pressures, etc.).
(c) To determine if the action leakage rate
				  has been exceeded, the owner or operator must convert the weekly flow rate from
				  the monitoring data obtained under 265.260, to an average daily flow rate
				  (gallons per acre per day) for each sump. Unless the Department approves a
				  different calculation, the average daily flow rate for each sump must be
				  calculated weekly during the active life and closure period.

South Carolina Code of Regulations › Chapter 61 - DEPARTMENT OF HEALTH AND ENVIRONMENTAL CONTROL › Subchapter 61-79 - Hazardous Waste Management Regulations › Part 61-79.265 - INTERIM STATUS STANDARDS FOR OWNERS AND OPERATORS OF HAZARDOUS WASTE TREATMENT, STORAGE, AND DISPOSAL FACILITIES › Subpart N - LANDFILLS › Section 61-79.265.N.301 - Design and operating requirements

Current through Register Vol. 48, No. 6, June 28, 2024
(a) The owner or operator of each new
				  landfill unit, each lateral expansion of a landfill unit, and each replacement
				  of an existing landfill unit must install two or more liners and a leachate
				  collection and removal system above and between such liners, and operate the
				  leachate collection and removal system, in accordance with 264.301(c), unless
				  exempted under 264.301(d), (e), or (f) of this chapter.
(b) The owner or operator of each unit
				  referred to in paragraph (a) of this section must notify the Department at
				  least sixty days prior to receiving waste. The owner or operator of each
				  facility submitting notice must file a Part B application within six months of
				  the receipt of such notice.
(c) The
				  owner or operator of any replacement landfill unit is exempt from paragraph (a)
				  of this section if:
(1) The existing unit was
				  constructed in compliance with the design standards of section3004(o)(1)(A)(i)
				  and (o)(5)(o)(1)(A)(i) and (o)(5) of the Resource Conservation and Recovery
				  Act; and
(2) There is no reason to
				  believe that the liner is not functioning as designed.

Current through Register Vol. 48, No. 6, June 28, 2024
(a) The
				  owner or operator of landfill units subject to 265.301(a) must submit a
				  proposed action leakage rate to the Department when submitting the notice
				  required under 265.301(b). Within 60 days of receipt of the notification, the
				  Department will: Establish an action leakage rate, either as proposed by the
				  owner or operator or modified using the criteria in this section; or extend the
				  review period for up to 30 days. If no action is taken by the Department before
				  the original 60 or extended 90 day review periods, the action leakage rate will
				  be approved as proposed by the owner or operator.
(b) The Department shall approve an action
				  leakage rate for landfill units subject to 265.301(a). The action leakage rate
				  is the maximum design flow rate that the leak detection system (LDS) can remove
				  without the fluid head on the bottom liner exceeding 1 foot. The action leakage
				  rate must include an adequate safety margin to allow for uncertainties in the
				  design (e.g., slope, hydraulic conductivity, thickness of drainage material),
				  construction, operation, and location of the LDS, waste and leachate
				  characteristics, likelihood and amounts of other sources of liquids in the LDS,
				  and proposed response actions (e.g., the action leakage rate must consider
				  decreases in the flow capacity of the system over time resulting from siltation
				  and clogging, rib layover and creep of synthetic components of the system,
				  overburden pressures, etc.).
(c) To
				  determine if the action leakage rate has been exceeded, the owner or operator
				  must convert the weekly or monthly flow rate from the monitoring data obtained
				  under 265.304 to an average daily flow rate (gallons per acre per day) for each
				  sump. Unless the Department approves a different calculation, the average daily
				  flow rate for each sump must be calculated weekly during the active life and
				  closure period, and monthly during the post-closure care period when monthly
				  monitoring is required under 265.304(b).

Current through Register Vol. 48, No. 6, June 28, 2024
(a) The
				  owner or operator of landfill units subject to 265.301(a) must develop and keep
				  on site until closure of the facility a response action plan. The response
				  action plan must set forth the actions to be taken if the action leakage rate
				  has been exceeded. At a minimum, the response action plan must describe the
				  actions specified in paragraph (b) of this section.
(b) If the flow rate into the leak detection
				  system exceeds the action leakage rate for any sump, the owner or operator
				  must:
(1) Notify the Department in writing of
				  the exceedance within 7 days of the determination;
(2) Submit a preliminary written assessment
				  to the Department within 14 days of the determination, as to the amount of
				  liquids, likely sources of liquids, possible location, size, and cause of any
				  leaks, and short-term actions taken and planned;
(3) Determine to the extent practicable the
				  location, size, and cause of any leak;
(4) Determine whether waste receipt should
				  cease or be curtailed, whether any waste should be removed from the unit for
				  inspection, repairs, or controls, and whether or not the unit should be
				  closed;
(5) Determine any other
				  short-term and longer-term actions to be taken to mitigate or stop any leaks;
				  and
(6) Within 30 days after the
				  notification that the action leakage rate has been exceeded, submit to the
				  Department the results of the analyses specified in paragraphs (b)(3), (4), and
				  (5) of this section, the results of actions taken, and actions planned. Monthly
				  thereafter, as long as the flow rate in the leak detection system exceeds the
				  action leakage rate, the owner or operator must submit to the Department a
				  report summarizing the results of any remedial actions taken and actions
				  planned.

Current through Register Vol. 48, No. 6, June 28, 2024
(a)
				  An owner or operator required to have a leak detection system under 265.301(a)
				  must record the amount of liquids removed from each leak detection system sump
				  at least once each week during the active life and closure period.
(b) After the final cover is installed, the
				  amount of liquids removed from each leak detection system sump must be recorded
				  at least monthly. If the liquid level in the sump stays below the pump
				  operating level for two consecutive months, the amount of liquids in the sumps
				  must be recorded at least quarterly. If the liquid level in the sump stays
				  below the pump operating level for two consecutive quarters, the amount of
				  liquids in the sumps must be recorded at least semi-annually. If at any time
				  during the post-closure care period the pump operating level is exceeded at
				  units on quarterly or semi-annual recording schedules, the owner or operator
				  must return to monthly recording of amounts of liquids removed from each sump
				  until the liquid level again stays below the pump operating level for two
				  consecutive months.
(c) "Pump
				  operating level" is a liquid level proposed by the owner or operator and
				  approved by the Department based on pump activation level, sump dimensions, and
				  level that avoids backup into the drainage layer and minimizes head in the
				  sump. The timing for submission and approval of the proposed "pump operating
				  level" will be in accordance with 265.302(a).
