AMENDMENT TO MONITORING AND REPORTING PROGRAM FOR MUNICIPAL SOLID WASTE LANDFILLS 2. Concentration Limits Beginning 9 October 1994, the Concentration Limit for any given Constituent of Concern or Monitoring Parameter in a Liven monitored medium (e.g., the uppermost aquifer) at a MSWLF shall be as follows, and shall be used as the basis of comparison with data from the Monitoring Points in that monitored medium: a. The background value established in the VVDRs by the Board for that constituent and medium, b. The constituent's background value, established anew during each Reporting Period using only data from all samples collected during that Reporting Period from the Background Monitoring Points for that monitored medium. Either: i. The mean (or median, as appropriate) and standard deviation (or other measure of central tendency, as appropriate) of the constituent's background data; or ii. The constituent's MDL, in cases where less than 10% of the background samples exceed the constituent's MDL; or C. A concentration limit greater than background, as approved by the Board for use during or after corrective action. 3. Monitoring Points Monitoring Points (including background) for detection monitoring shall be those listed in the Monitoring and Reporting Program which is incorporated in the existing waste discharge requirements. 4. Points of Compliance The Points of Compliance, for each MSWLF, either shall be those listed in the Monitoring and Reporting Program which is incorporated in the existing waste discharge requirements, or shall be established as required by Chapter 15. 5. Compliance Period The Compliance Period for the MSWLF shall be the number of years equal to the active life of the MSWLF plus the closure period. Each time the Standard is 'exceeded (i.e., a release is discovered), the MSWLF begins a Compliance Period on the date the Board directs the Discharger to begin an Evaluation Monitoring Program. If the Discharger's Corrective Action Program (CAP) has not achieved compliance with the Standard by the scheduled end of the Compliance Period, the Compliance Period is automatically extended until the MSWLF has been in continuous compliance for at least three consecutive years.
