AMENDMENT TO MONITORING AND REPORTING PROGRAM -5- FOR MUNICIPAL SOLID WASTE LANDFILLS ii. For each Attachment 3 constituent that is newly added to the MSWLF's COC list due to this order, the discharger shall establish a reference background value by analyzing at least one sample each quarter from each Background Monitoring Point for a period of at least one year, beginning with the date of this Program. Once this reference set of background data is collected, the discharger shall include it as a separate, identified item in the next monitoring report submittal. b. For MSWLFs having a functioning LCRS: Beginning on 9 October 1994, for any MSWLF equipped with both a liner and a leachate collection and removal system (LCRS) that produces leachate: i. The COC list shall include: (1) all waste constituents listed in the waste discharge requirements as of the effective date of this Order; and (2) each Attachment 3 constituent that is not already a COC for the MSWLF, and that both: (a) is detected in a sample of the MSWLF's leachate which the discharger shall collect during Fall of each year; and (b) is also detected in a retest leachate sample collected the following Spring. The discharger need take and analyze this retest sample only in cases where the annual leachate sample, taken the previous Fall under this section, identifies new-CDCs. The retest sample shall be analyzed only for the new-COCs detected in the Fall sample; and (3) the following additional COCs: dissolved or total organic carbon, dissolved iron, carbonate, bicarbonate, alkalinity, dissolved aluminum, dissolved chromium VI, and dissolved manganese. ii. For each Attachment 3 constituent that is newly added to the MSWLF's COC list, the discharger shall establish a reference background value in each monitored medium by analyzing at least one sample each quarter from each Background Monitoring Point for a period of at least one year following the date the constituent is submitted to the Board as a new COC. Once this reference set of background data is collected, the discharger shall include it as a separate, identified item in the next monitoring report submittal. For sites which have multi-unit detection monitoring systems, if any MSWLF unit lacks a functioning LCRS, COCs shall be determined as above under"a. For MSWLFs lacking a functioning LCRS". The discharger shall monitor all COCs every five years (or more frequently if required by the existing Monitoring and Reporting Program).
