25 Pa. Code § 273.276 - Leachate analysis and sludge handling
(a) Upon commencement of leachate flow from
the facility, the operator shall sample and analyze the following:
(1) On a daily basis, the average flow rate
and volume of leachate flowing from the landfill into the leachate storage and
treatment system.
(2) On a
quarterly basis, the chemical composition of leachate flowing into the leachate
treatment system, including total alkalinity, specific conductance, chlorides,
sulfates, total dissolved solids, chemical oxygen demand, metals and volatile
organic analysis. The analysis shall be sufficient to determine the impact of
leachate on the liner system, the effectiveness of the leachate treatment
system, the need for modification of the groundwater monitoring system or the
effluent limitations in an NPDES permit and the actual characteristics of
leachate from the waste disposed at the facility. For the purpose of this
quarterly analysis, the leachate sample shall be collected from the influent
storage tank or impoundment and shall be representative of the average mixed
influent leachate quality.
(b) Sludges resulting from the treatment of
leachate may be disposed at the facility if the sludges are not hazardous under
Article VII (relating to hazardous waste management).
