Section 289.456 - Leachate analysis and sludge handling(a) Upon commencement of leachate flow from the facility, the operator shall sample, analyze and maintain a record of the following: (1) On a daily basis, the average flow rate and volume of leachate flowing from the disposal impoundment into the leachate storage and treatment system.(2) On a quarterly basis unless otherwise provided in the permit, the chemical composition of leachate flowing into the leachate treatment system. 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 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).The provisions of this § 289.456 amended January 12, 2001, effective 1/13/2001, 31 Pa.B. 235.
