STANDARD PROVISIONS AND REPORTING REQUIREMENTS September 1993 FOR WASTE DISCHARGE REQUIREMENTS FOR DISCHARGES REGULATED BY CHAPTER 15 AIvD/OR PART 258 -14- All retests shall be carried out only for the Monitoring Point(s) for which a release is tentatively indicated, and onlv for the Constituents of Concern or Monitoring Parameters which triggered the indication there. as follows: 1. If an ANOVA method was used for the original data, the retest shall involve only a repeat of the multiple comparison procedure, carried out separately on each of the two new suites of samples taken from the indicating Monitoring Point; ?. If the Method of Proportions statistical test was used for the original data, the retest shall consist of a full repeat of the statistical test for the indicated constituent or parameter, performed separately on each of the new sample suites from the indicating Monitoring Point: 3. If the non-statistical method was used for the original data: a. Because the VOC Monitoring Parameters [VOCwater or VOCs a] each address, as a single parameter, an entire family of constituents which are likely to be present in any landfill release, the scope of the laboratory analysis for each retest sample shall include all VOCs detectable in that retest sample. Therefore, a confirming retest for either parameter shall have validated the original indication even if the suite of constituents in the confirming retest sample(s) differs from that in the sample which initiated the retest; b. Because all Constituents of Concern that are jointly addressed in the non-statistical testing remain as individual Constituents of Concern, the scope of the laboratory analysis for the nonstatistical retest samples shall be narrowed to involve only those constituents detected in the sample which initiated the retest. Response to Detection in Background of VOCs for any other constituent which is expected to be"zero"in background and thus not amenable to statistical analysis) 1. Except as provided in 3. below, any time the laboratory analysis of a sample from a Background Monitoring Point, sampled for VOCs, shows either (1) two or more VOCs at or above their respective MDL, or (2) one VOC at or above its respective PQL, then the Discharger shall: a. immediately notify the Board by phone, b. follow up with written notification by certified mail within seven days, C. obtain two new independent VOC samples from that Background Monitoring Point d. and send such samples for laboratory analysis of all detectable VOCs within thirty days. 2. If either or both the new samples validates the presence of VOC(s), using the above procedure, the Discharger shall:
