Current through Register Vol. 54, No. 52, December 28, 2024
(a) An
application shall contain a plan for leachate treatment from the proposed
facility in a manner that complies with §§
288.451-288.457 (relating to additional
operating requirements-leachate treatment). The plan shall include the
following:
(1) An estimate of the quality and
quantity of leachate 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" United States 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 leachate 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 an onsite 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 and
regulations thereunder.
(b) If interim vehicular transportation to an
offsite treatment facility is proposed, the applicant shall do the following:
(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 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 a 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 that is
consistent with the permit, the act and this chapter.
(4) Submit plans, designs and cross sections
for an onsite pretreatment facility as required by §
288.453(b)(1)
(relating to leachate transportation).
(c) If recirculation of raw or pretreated
leachate is proposed in conjunction with another 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.
This section cited in 25 Pa. Code §
288.411 (relating to general
requirements); 25 Pa. Code §
288.414 (relating to modification
of leachate treatment plan); and 25 Pa. Code §
288.455 (relating to leachate
collection and storage).
