MONITORING AND REPORTING PROGRAM FORWARD INC., FORWARD LANDFILL SAN JOAQUIN COUNTY b. For WMUs havinga functioning LCRS: I For any WMU equipped with both a liner and a leachate collection and removal system (LCRS) that produces leachate: (1) The COC list shall include: (a) all waste constituents listed in the waste discharge requirements as of the effective date of this Order, and -8- (b) each Attachment E constituent that is not already.a COC for the WMU, and that both: i. is detected in a sample of the WMU's leachate which the discharger shall collect during Fall of each year; and ii. is also detected in a retest leachate sample colleeted the €glowing 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-COCs. The retest sample shall be analyzed only for the new-COCs detected in the Fall sample; and (c) the following additional COCl: dissolved or total organic carbon, dissolved iron, carbonate, bicarbonate, alkalinity, dissolved aluminum, dissolved chromium VI, and dissolved manganese. (2) For each Attachment E constituent that is newly added to the WMU'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 landfill unit lacks a functioning LCRS, COCs shall be determined as above under "a. For MSWLFs lacking a functioning LCRS". The discharger shall monitor all COCl every five years. 2. Concentration Limits The Concentration Limit for any given Constituent of Concern or Monitoring Parameter in a given monitored medium (e.g., the uppermost aquifer) at a shall be as follows, and shall be used as the basis of comparison with data from the Monitoring Points in that monitored medium:
