accompany the certification of a new unit or the lateral extension of an
existing unit:
(a) A daily activity log, as
specified in subrule (3) of this rule.
(b) Records of any natural soil barrier, as
specified in R 299.4912.
(c)
Compacted soil liner records, as specified in R 299.4917.

(f) Final elevations, as documented on
as-built plans specified in subrule (4) of this rule.
(g) Diagrams that show the location of all
tests on the liner and liner system.
(2) The CQA officer shall certify that a
landfill that has reached final grade, or has otherwise closed, has received
final cover as specified in these rules, the CQA plan, and engineering plans
approved by the department. All of the following construction records shall
accompany an engineer's certification of a unit that has received final cover:
(a) A daily activity log, as specified in
subrule (3) of this rule.
(b) Soil
cover liner records, as specified in R 299.4917.
(c) Flexible membrane cover liner records, as
specified in R 299.4918.
(d)
Observations and tests of the other layers of the final cover to ensure that
the design specifications are met. These activities shall include inspection of
the completed cover slope, vegetation, and drainage conduits to ensure that
they are in compliance with the specified design.
(e) Final elevations, as documented on
as-built plans specified in subrule (4) of this rule.
(3) A daily activity log shall be completed
by the on-site construction supervisor for each day of construction. A daily
activity log shall include all of the following information:
(a) The name and title of construction
supervisor.
(b) The date of
activity.
(c) Weather, including
maximum and minimum temperatures and amount of precipitation, if any.
(d) The type of activity conducted.
(e) A summary of all quality assurance tests
conducted, indicating which tests passed and failed specifications.
(f) Documentation of all repairs made on the
liner system.
(4) The
CQA officer shall prepare as-built plans to document all elevations of a newly
constructed landfill and closed landfill. All elevations shall be referenced to
United States geological survey datum. As-built plans shall indicate all of the
following information:
(a) The dimensions and
maximum and minimum elevations of each cell in each direction. Elevations of
each bottom liner component shall be within 0.2 feet of approved plans, if each
component meets the minimum thickness requirements of these rules.
(b) The location and elevation of all sumps
and gravity pipelines. Elevations of sumps and pipelines shall be within 0.2
feet of approved plans.
(c) The
location and elevation of all drainage facilities.
(d) The surface elevations of the final
cover. The elevation of the final cover may deviate up to 1 foot above approved
plans, if each component meets the minimum thickness requirements of these
rules.
(5) An engineer's
certification under this rule shall be a statement or declaration that is based
on his or her knowledge and review of the construction records that are
specified in this rule. The engineer's certification of construction conditions
shall not relieve the owner, operator, or any other party from meeting other
applicable requirements of the act and these rules.
