(1) COMPLIANCE
CERTIFICATION. No later than March 31 of each year and continuing until
otherwise specified by the department, the owner or operator of any licensed
landfill which is in operation as of July 1, 1996, or any licensed, closed
landfill with an approved total design capacity exceeding 1,000,000 cubic yards
shall prepare and submit to the department a compliance certification. The
certification, shall be prepared and signed by the owner or operator of the
landfill, certified facility manager, solid waste manager or person most
directly responsible for the landfill's day to day operation. The signer shall
certify that he or she is aware of all approved plans for the landfill, all
department conditions of approval, and all applicable solid waste statutory and
administrative rules, and that to the best of the signer's knowledge,
information and belief, the landfill is or is not in substantial compliance
with all approved plans and requirements. For landfills which are in full
compliance, no narrative is required beyond the certification statement. For
other landfills, all known areas of noncompliance shall be clearly indicated.
This subsection does not impose personal liability upon certified facility
managers or certified site operators.
(2) AUDITS. As specified under s.
289.91, Stats., the
department may perform audits of any landfill. Following a minimum 30-day
advance notification, the landfill owner or operator shall ensure that during
the period of the audit, a conference room or adequate office space is provided
for department personnel, and that proper technical personnel representing the
owner are present to respond to department inquiries regarding the landfill.
The owner or operator shall also ensure that any of the information in pars.(a)
to (j) or any other information specified by the department in its audit
notification letter is available in an organized fashion for the department to
review. The owner or operator shall provide copies of requested information for
the department to take with them following the audit. If requested by the
department, the owner, operator or their representatives shall present the
requested information to the department during the audit and also participate
in an inspection of any aspects of the landfill which the department requests.
The owner or operator shall provide the department with access to all items or
areas of the landfill which are related to landfill performance or to
compliance with approved plans, solid waste administrative rules or statutes.
(a) One or more full-sized plan view drawings
clearly annotated to show the following:
1.
The portions of the landfill which currently are receiving solid
waste;
2. All portions of the
landfill which have been filled, but have not yet been brought to approved
final grades;
3. All portions of
the landfill which have been filled to approved final grade and the extent to
which the final cover system has been placed;
4. All portions of the landfill which
currently are undergoing development or closure;
5. All portions of the landfill which have
yet to be developed; and
6. Any
areas which have been filled above approved final grades or beyond the approved
limits of filling.
(b)
Calculations based on the most recent topographic survey which show the design
capacity volume which has been filled, the remaining design capacity volume,
and the estimated remaining site life. All assumptions used in the calculation
of estimated remaining site life shall be provided. If the currently estimated
remaining site life is one or more years less than that assumed in the latest
long-term care calculations, changes shall be evaluated and proposed to the
annual long-term care inpayment required to be made by owners using escrow
accounts, trusts or deposits with the department to provide proof of financial
responsibility for long-term care.
(c) Plan view drawings or sketches
documenting each leachate collection line cleaning and leachate transfer line
pressure testing event. Separate drawings or sketches shall be submitted for
each event, with each drawing using as a base the landfill's entire leachate
collection and transfer piping system. If legibility is not compromised, these
drawings may be 11-inch by 18-inch pull-out drawings.
(d) For landfills which have not been
required to begin a formal ch. NR 140 investigation, but which have experienced
over the past 3 year reporting period: an ES exceedance; more than 2 PAL
exceedances for the same parameter at the same well; or results where the
average of all data for a parameter at a well exceeds a PAL, a summary of all
groundwater data collected to date for the well or wells which have experienced
the results presented graphically using either time versus concentration graphs
or box plots.
(e) An evaluation of
the performance of the leachate collection and removal system which shall
include graphed results of monthly leachate removal volumes from the beginning
of filling at the landfill to the end of the current calendar year. Leachate
volume data shall be graphed separately for each leachate collection tank or
lift station. Leachate removal volumes shall also be graphed as a depth over
the area of liner which has been constructed at a given point in time. Graphs
shall note when each phase or portion thereof was constructed or closed.
Monthly leachate data shall be annualized by multiplying by 12 and reported in
units of inches per year. All leachate quality data for BOD or COD, including
that regularly performed at the request of wastewater treatment facilities,
shall be presented graphically. Graphs of monthly average BOD or COD in mg/l
shall be presented as well as pounds of BOD or COD removed per month from the
facility. Also included shall be a tabulation of all past monthly leachate
removal volumes and average BOD or COD concentrations.
(f) Graphs of leachate head conditions on the
liner and trends with time shall be reported. Where lysimeters or gradient
control systems are present under the liner, fluid collection quantity and
quality data shall also be tabulated.
(g) Graphs and tables evaluating the
performance of the gas extraction system over the previous 3 years including:
the volume of gas removed and average methane concentration to be presented on
a no less frequent basis than quarterly; the condition of each gas extraction
well and identification of any wells which need to be replaced or that have
been replaced; a summary of the hours of operation and down time of the gas
recovery plant or blower; and a summary of any exceedances of the lower
explosive limit of any gasses detected in gas monitoring wells located outside
the limits of waste. This information shall also be presented graphically to
the extent possible.
(h) An
evaluation of settlement which the landfill has undergone, and any evidence of
surface water ponding, poor drainage, differential settlement, erosion or other
disruption of the final cover structure.
(i) An evaluation of the integrity of the
vegetation on the final covered or interim-covered areas, integrity of the
final cover, summary of erosion control efforts, surface stabilization efforts
and any evidence of animal intrusion.
(j) Where applicable, a summary of the
occurrences of liquids in secondary containment systems for leachate drain
lines, condensate drain lines, manholes, collection tanks and lift stations and
any corrective measures taken or proposed in response to the presence of
liquids.
