1 / The requested method for TSS, EPA 160.2, is not currently approved by the EPA to be used for wastewater compliance. / Method must be in accordance with
40 CFR 136.
KY DOW has inserted SM 2540 D-1997 as the method for TSS on the laboratory’s method-analyte list. Please confirm which approved method the laboratory will be using and update documents accordingly.
Note: SM 2540 D-2011 (SM 22nd Ed.) is also approved as a test method for TSS. / 40 CFR 136.3

Update TSS SOP to include year of SM committee approval for the specific version of the method in use (SM 2540 D-1997).
Document will be reviewed at time of on-site audit. / N/A
2 / The requested method for pH, EPA 150.2, is not consistent with the method detailed in the laboratory’s SOP (PROC.052.001). EPA 150.2 is an automated procedure. EPA 150.1 is the electrode method similar to the method described in the SOP. However, EPA 150.1 is not currently approved by the EPA to be used for wastewater compliance. / Method must be in accordance with
40 CFR 136.
KY DOW has inserted SM 4500 H+ B-2000 as the method for TSS on the laboratory’s method-analyte list. Please confirm which approved method the laboratory will be using and update documents accordingly.

PROC.001.016, PROC.001.031, PROC.001.032, PROC.001.033.
  • Update Table 25.1 to include information for TSS, oil and grease, and pH.
  • QAP needs to describe the use of control charts (or other trend analyses of quality control results) to monitor for trends and ensure acceptance criteria are met. Controls charts are to include all of the relevant results, not just the passing results.
/ WWCM1 Chapter II Sections
3.3, 3.4, 3.6, 3.7
KWLCP App2
Section 8 / / Acceptable.

Document will be reviewed at time of on-site audit. / N/A
4 / SOPs:
  • Effective dates on SOPs are prior to the approval dates.
  • TSS SOP has not been signed (approved) by the lab director (Eric Cole).
  • pH SOP only references the instrument manual, does not include review/revision history sheet, and only 3 of 7 pages were submitted.
/
  • SOPs must be approved by the appropriate personnel prior to becoming effective.
  • Revise pH SOP accordingly (method reference, revision sheet) and resubmit in its entirety to KY DOW.

5 / MDLs and DOCs:
  • The instrument ID is not recorded for DOC or MDL studies.
  • QAP does not specify frequency of MDL study.

Chapter III
Sections 7.1.1, 7.1.4 / / Acceptable. / N/A
6 / QAP states that Advanced TENORM Services does not collect samples. / pH and temperature measurements for compliance samples must be obtained within hold time (temperature immediately, pH within 15 minutes of collection). Reported results (i.e., DMR) must be from analyses performed within hold time by personnel of a lab certified to perform the analyses. / 40 CFR 136.3 Table II
WWCM1
Chapter II
Section 10 / / Acceptable. / N/A
7 / pH SOP does not include recording of the slope or an acceptance range for the slope. / Record pH meter slope monthly, after calibration. Slope shall be between 95% and 105%. / WWCM1
Chapter II
Section 8.1.5 / / Acceptable. / N/A
8 / pH SOP states ± 0.2 pH units as the acceptance range for calibration verification. / A pH calibration check solution shall be analyzed and read within ± 0.1 S.U. of the true value. / WWCM1
