Ohio Admin. Code 3745-54-19 - Construction quality assurance (CQA) program
(A) CQA program.
(1) A CQA program is required for all surface
impoundment, waste pile, and landfill units that are required to comply with
paragraphs (C) and (D) of rule 3745-56-21, paragraphs (C) and (D) of rule
3745-56-51, and paragraphs (C) and (D) of rule
3745-57-03 of the Administrative
Code. The program must ensure that the constructed unit meets or exceeds all
design criteria and specifications in the permit. The program must be developed
and implemented under the direction of a CQA officer who is a registered
professional engineer.
(2) The CQA
program must address the following physical components, where applicable:
(a) Foundations;
(b) Dikes;
(c) Low-permeability soil liners;
(d) Geomembranes (flexible membrane liners);
(e) Leachate collection and
removal systems and leak detection systems; and
(f) Final cover systems.
(B) Written CQA plan. The owner or
operator of units subject to the CQA program under paragraph (A) of this rule
must develop and implement a written CQA plan. The plan must identify steps
that will be used to monitor and document the quality of materials and the
condition and manner of their installation. The CQA plan must include:
(1) Identification of applicable units, and a
description of how they will be constructed.
(2) Identification of key personnel in the
development and implementation of the CQA plan, and CQA officer qualifications.
(3) A description of inspection
and sampling activities for all unit components identified in paragraph (A)(2)
of this rule, including observations and tests that will be used before,
during, and after construction to ensure that the construction materials and
the installed unit components meet the design specifications. The description
must cover:
(a) Sampling size and locations;
(b) Frequency of testing;
(c) Data evaluation procedures;
(d) Acceptance and rejection
criteria for construction materials;
(e) Plans for implementing corrective
measures; and
(f) Data or other
information to be recorded and retained in the operating record under rule
3745-54-73 of the Administrative
Code.
(C)
Contents of program.
(1) The CQA program must
include observations, inspections, tests, and measurements sufficient to
ensure:
(a) Structural stability and
integrity of all components of the unit identified in paragraph (A)(2) of this
rule;
(b) Proper construction of
all components of the liners, leachate collection and removal system, leak
detection system, and final cover system, according to permit specifications
and good engineering practices, and proper installation of all components
(e.g., pipes) according to design specifications;
(c) Conformity of all materials used with
design and other material specifications under rules 3745-56-21, 3745-56-51,
and 3745-57-03 of the Administrative
Code.
(2) The CQA
program must include test fills for compacted soil liners, using the same
compaction methods as in the full scale unit, to ensure that the liners are
constructed to meet the hydraulic conductivity requirements of paragraph
(C)(1)(a)(ii) of rule 3745-56-21, paragraph (C)(1)(a)(ii) of rule 3745-56-51,
and paragraph (C)(1)(a)(ii) of rule
3745-57-03 of the Administrative
Code in the field. Compliance with the hydraulic conductivity requirements must
be verified by using in-situ testing on the constructed test fill. The director
may accept an alternative demonstration, in lieu of a test fill, where data are
sufficient to show that a constructed soil liner will meet the hydraulic
conductivity requirements of paragraph (C)(1)(a)(ii) of rule 3745-56-21,
paragraph (C)(1)(a)(ii) of rule 3745-56-51, and paragraph (C)(1)(a)(ii) of rule
3745-57-03 of the Administrative
Code in the field.
(D)
Certification. Waste must not be received in a unit subject to this rule until
the owner or operator has submitted to the director by certified mail or hand
delivery a certification signed by the CQA officer that the approved CQA plan
has been successfully carried out and that the unit meets the requirements of
paragraph (C) or (D) of rule 3745-56-21, paragraph (C) or (D) of rule
3745-56-51, or paragraph (C) or (D) of rule
3745-57-03 of the Administrative
Code; and the procedure in paragraph (L)(2)(b) of rule
3745-50-58 of the Administrative
Code has been completed. Documentation supporting the CQA officer's
certification must be furnished to the director upon request.
