Submit the completed and appropriately executed Residuals Source Certification (FORM: RSC 11-15) form. Please do not
make any unauthorized content changes to this form. If necessary for clarity or due to space restrictions, attachments to th e
application may be made, as long as the attachments are numbered to correspond to the section and item to which they refer .
For new or renewed permits, submit a separate certification for each source facility.
For modified permits, submit a separate certification for only those facilities that are affected by the proposed modification.
Complete the residuals source facility summary page. List all new, renewed, or modified facilities.
B. Residuals Source-Generating Facility Information:

and/or disposed, including any chemicals, amendments, or other additives that are added to the residuals during
processing.
Sampling plan - A detailed sampling plan for the residuals source-generating facility. Ensure that the plan identifies
sampling points, sampling frequency, sample type, as well as the Division -certified laboratory to be used. In addition,
ensure that the plan details how the facility and/or the residuals are monitored for any applicable pathogen reduction and
vector attraction reduction requirements. Note that all sampling and monitoring must be completed on the residuals as
they are to be land applied, distributed, and/or disposed.

Type and volume of residuals treatment: The biosolids thermal dryer is designed to process up to 9.2 dry tons per day
(DT/d) of dried biosolids, operating 24 hours per day 5 days per week at future 2045 maximum month conditions. This
equates to a dried biosolids production rate of 10 wet tons per day (WT/d), equal to 800 ft3/d, and 50 WT/week equal to
4,000 ft3/week, assuming a total dry solids content of 92% per the dryer equipment basis of design, a dried biosolids bulk

Enthalpy Analytical, LLC – Ultratrace. The results from this analysis indicated that the residuals contain very low levels of
PFAS and are not currently industrially impacted. Refer to Section 3.1 of the Basis of Design Report included in Appendix B of
the DCAR Application submittal for detailed analysis and discussion of the PFAS sampling and results.
