25 Pa. Code § 277.162 - Leachate treatment plan
(a)
The application shall contain a plan for treating leachate from the proposed
facility in a manner that complies with §§
277.271-277.276. The plan shall include:
(1) An estimate of the quality and quantity
of leachate that is estimated to be produced annually by the facility, based on
the water balance method set forth in"Use of Water Balance Method for
Predicting Leachate Generation from Solid Waste Disposal Sites" U. S. EPA
SW-168 (1975), or another method of accurately projecting leachate flows that
is approved by the Department, in writing. The estimate shall include the
30-day leachate volume and average flow rate for each month of the year. A
separate estimate shall be submitted for anticipated leachate generation at the
end of 5-year increments of operation for 20 years, or until closure, whichever
date is earlier. For existing facilities, current leachate generation shall be
included with this separate estimate.
(2) Plans, designs and cross sections for the
proposed collection and handling system.
(3) Plans, designs and cross sections for
onsite treatment or disposal systems, including tanks and impoundments that are
proposed to be used or constructed for storage, pretreatment or treatment of
leachate from the facility.
(4) If
a treatment system already in operation is proposed to treat leachate from the
facility, a description of the system, including its NPDES permit number, its
capability to treat leachate from the facility, and its compliance status under
The Clean Streams Law (35 P. S. §§
691.1-691.1001) and regulations
thereunder.
(b) If
interim vehicular transportation to an offsite treatment facility is proposed,
the applicant shall:
(1) Provide a copy of a
signed contractual agreement with the operator of a primary offsite facility
that provides for treatment of leachate at the facility, and which covers the
period of time that offsite treatment will be provided; or provide a signed
letter of intent from the operator of the offsite facility to enter a
contractual agreement for leachate treatment if the permit application is
approved by the Department.
(2)
Provide a copy of a signed contractual agreement with the operator of a second
offsite treatment facility that provides for backup treatment of leachate at
the second treatment facility if, for any reason, leachate cannot be treated by
the primary treatment facility operator; or provide a signed letter of intent
from the operator of the second offsite facility to enter the contractual
agreement if the permit application is approved by the Department.
(3) Submit additional bond to the Department
in an amount sufficient to pay for the cost of vehicular transportation and
offsite leachate treatment until final closure if the landfill operator fails
to provide offsite treatment in a manner consistent with the permit, the act
and this chapter.
(4) Submit plans,
designs and cross sections for an onsite pretreatment facility as required by
§
277.273(b)(1)
(relating to leachate transportation).
(c) If leachate recirculation of raw or
pretreated leachate is proposed in conjunction with another treatment method,
the application shall describe the following:
(1) The proposed leachate distribution method
over the filled area, including designs and cross sections.
(2) Methods that will be used to prevent
leachate seeps and breakouts.
(3)
Methods that will be used to prevent odors, runoff and ponding.
(d) The application shall also
contain a schedule and method for cleaning sludges from the leachate storage
and treatment system, and a plan for disposing of the sludges.
