the reference method).

Wite-Out®, correction tape, or similar products designed to obliterate documentation shall not to be used; instead, the correction shall be written adjacent to the error. The correction shall be initialed by
the responsible individual and the date of change documented.

PROCEDURE – Thermometer Calibration LAB
SOP EXPLANATION
11
Does the compliance temperature-measuring device have a valid NIST certificate? [Approved Procedure for the Analysis of VAR Option 5: Aerobic Processes at Greater Than 40 °C] “Valid” is considered as having a stated accuracy of ± 0.5°C and being within its expiration date
12
If the compliance temperature-measuring device does not have a valid NIST certificate, is the device checked initially before use and every 12 months thereafter against a Reference Temperature-Measuring Device? [Approved Procedure for the Analysis of VAR Option 5: Aerobic Processes at Greater Than 40 °C]

Date of verification: ___________ This may be performed by a contract laboratory. Maintain comparison data and accuracy documentation of Reference Temperature-Measuring Device information listed below for 5 years.
13
Does the Reference Temperature-Measuring Device used for comparison have a stated accuracy of at least ± 0.5 °C and is it within its expiration date? [Approved Procedure for the Analysis of VAR Option 5: Aerobic Processes at Greater Than 40 °C]

PROCEDURE – Sample Analysis LAB
SOP EXPLANATION
16
What is the sewage sludge type (e.g., composted, from aerobic digestion, etc.)? [NC WW/GW LCB Approved Procedure for the Analysis of VAR Option 5: Aerobic Processes at Greater Than 40 °C]
Sludge type:

This Option must be used for composted sewage sludge. This option may also be applied to sewage sludge from other aerobic processes such as aerobic digestion as long as temperature requirements can be met and the sewage sludge is maintained in an aerobic state for the treatment period; however, Options 3 and 4 are likely to be easier to meet for these types of sewage sludges.

17
Is the sewage sludge aerobically treated for at least 14 days? [NC WW/GW LCB Approved Procedure for the Analysis of VAR Option 5:
Aerobic Processes at Greater Than 40 °C]
18
Is the temperature measured at permit specified locations each of those 14 days? [NC WW/GW LCB Approved Procedure for the Analysis of VAR Option 5: Aerobic Processes at Greater Than 40 °C]
19 Is the location documented? [Field: 15A NCAC 2H .0805 (g) (1) [Non-field: 15A NCAC 2H .0805 (a) (7) (E)]
20
Is the temperature measured within 0.3 M (1 foot) of the surface of the unfinished compost? [NC WW/GW LCB Approved Procedure for the Analysis of VAR Option 5: Aerobic Processes at Greater Than 40 °C]

It has been found that points within 0.3 m (1 foot) of the surface of aerated static piles may be unable to reach these temperatures, and for this reason, it is recommended that a 0.3 m
(1 foot) or greater layer of insulating material be placed over all surfaces of the pile. Finished compost is often used for insulation. It must be noted that because the insulation will most likely be mixed into the composted material during post-processing or curing, compost used as an insulation material must be a Class A material so as not to reintroduce pathogens into the composting sewage sludge. Regardless of whether an insulating layer is used, temperature measurements must be performed within 0.3 m (1 foot) of the surface of the unfinished compost.
21 Is the depth of measurement documented? [Field: 15A NCAC 2H .0805 (g) (1)] [Non-field: 15A NCAC 2H .0805 (a) (7) (E)]
22

(113 °F)? [NC WW/GW LCB Approved Procedure for the Analysis of
