Current through Bulletin 2024-06, March 15, 2024
(a) Inspections by a qualified person.
(1) All CCR surface impoundments and any
lateral expansion of a CCR surface impoundment shall be examined by a qualified
person as follows:
(i) At intervals not
exceeding seven days, inspect for any appearances of actual or potential
structural weakness and other conditions which are disrupting or have the
potential to disrupt the operation or safety of the CCR unit;
(ii) At intervals not exceeding seven days,
inspect the discharge of all outlets of hydraulic structures which pass
underneath the base of the surface impoundment or through the dike of the CCR
unit for abnormal discoloration, flow or discharge of debris or sediment;
and
(iii) At intervals not
exceeding 30 days, monitor all CCR unit instrumentation.
(iv) The results of the inspection by a
qualified person shall be recorded in the facility's operating record as
required by Subsection R315-319-105(g)(5).
(2) Timeframes for inspections by a qualified
person
(i) Existing CCR surface impoundments.
The owner or operator of the CCR unit shall initiate the inspections required
under Subsection R315-319-83(a) no later than October 19, 2015.
(ii) New CCR surface impoundments and any
lateral expansion of a CCR surface impoundment. The owner or operator of the
CCR unit shall initiate the inspections required under Subsection
R315-319-83(a) upon initial receipt of CCR by the CCR unit.
(b) Annual inspections by a qualified professional engineer.
(1) If
the existing or new CCR surface impoundment or any lateral expansion of the CCR
surface impoundment is subject to the periodic structural stability assessment
requirements under Subsection R315-319-73(d) or Subsection R315-319-74(d), the
CCR unit shall additionally be inspected on a periodic basis by a qualified
professional engineer to ensure that the design, construction, operation, and
maintenance of the CCR unit is consistent with recognized and generally
accepted good engineering standards. The inspection shall, at a minimum,
include:
(i) A review of available
information regarding the status and condition of the CCR unit, including, but
not limited to, files available in the operating record, e.g., CCR unit design
and construction information required by Subsections R315-319-73(c)(1) and
74(c)(1), previous periodic structural stability assessments required under
Subsections R315-319-73(d) and 74(d), the results of inspections by a qualified
person, and results of previous annual inspections;
(ii) A visual inspection of the CCR unit to
identify signs of distress or malfunction of the CCR unit and appurtenant
structures; and
(iii) A visual
inspection of any hydraulic structures underlying the base of the CCR unit or
passing through the dike of the CCR unit for structural integrity and continued
safe and reliable operation.
(2) Inspection report. The qualified
professional engineer shall prepare a report following each inspection that
addresses the following:
(i) Any changes in
geometry of the impounding structure since the previous annual
inspection;
(ii) The location and
type of existing instrumentation and the maximum recorded readings of each
instrument since the previous annual inspection;
(iii) The approximate minimum, maximum, and
present depth and elevation of the impounded water and CCR since the previous
annual inspection;
(iv) The storage
capacity of the impounding structure at the time of the inspection;
(v) The approximate volume of the impounded
water and CCR at the time of the inspection;
(vi) Any appearances of an actual or
potential structural weakness of the CCR unit, in addition to any existing
conditions that are disrupting or have the potential to disrupt the operation
and safety of the CCR unit and appurtenant structures; and
(vii) Any other change(s) which may have
affected the stability or operation of the impounding structure since the
previous annual inspection.
(3) Timeframes for conducting the initial
inspection
(i) Existing CCR surface
impoundments. The owner or operator of the CCR unit shall complete the initial
inspection required by Subsections R315-319-8(b)(1) and (2) no later than
January 18, 2016.
(ii) New CCR
surface impoundments and any lateral expansion of a CCR surface impoundment.
The owner or operator of the CCR unit shall complete the initial annual
inspection required by Subsections R315-319-83(b)(1) and (2) is completed no
later than 14 months following the date of initial receipt of CCR in the CCR
unit.
(4) Frequency of
inspections.
(i) Except as provided for in
Subsection R315-319-83(b)(4)(ii), the owner or operator of the CCR unit shall
conduct the inspection required by Subsections R315-319-83(b)(1) and (2) on an
annual basis. The date of completing the initial inspection report is the basis
for establishing the deadline to complete the first subsequent inspection. Any
required inspection may be conducted prior to the required deadline provided
the owner or operator places the completed inspection report into the
facility's operating record within a reasonable amount of time. In all cases,
the deadline for completing subsequent inspection reports is based on the date
of completing the previous inspection report. For purposes of Section
R315-319-83, the owner or operator has completed an inspection when the
inspection report has been placed in the facility's operating record as
required by Subsection R315-319-105(g)(6).
(ii) In any calendar year in which both the
periodic inspection by a qualified professional engineer and the quinquennial,
occurring every five years, structural stability assessment by a qualified
professional engineer required by Subsections R315-319-73(d) and 74(d) are
required to be completed, the annual inspection is not required, provided the
structural stability assessment is completed during the calendar year. If the
annual inspection is not conducted in a year as provided by Subsection
R315-319-83(b)(4)(ii), the deadline for completing the next annual inspection
is one year from the date of completing the quinquennial structural stability
assessment.
(5) If a
deficiency or release is identified during an inspection, the owner or operator
shall remedy the deficiency or release as soon as feasible and prepare
documentation detailing the corrective measures taken.
(c) The owner or operator of the CCR unit shall comply with the recordkeeping requirements specified in Subsection R315-319-105(g), the notification requirements specified in Subsection R315-319-106(g), and the internet requirements specified in Subsection R315-319-107(g).
