A. (6.) CALCULATION OF HFPO-DA & PFMOAA REMOVAL/LOADS
a. The Permittee shall calculate monthly removal efficiency for HFPO-DA and PFMOAA as follows:
%Removal = Influent -Effluent
Influent
Where:
Influent — monthly average influent concentration
Effluent — monthly average effluent concentration
b. The Permittee shall calculate monthly load for HFPO-DA and PFMOAA as follows:
Monthly C Load = C x TMF x 8.I
Where:
C — Mon ly average concentrationeach compound (mg/L)
TMF — Total Monthly Flow of wastewater discharged during the month (MG/month)
8.34 — conversion factor from (mg/L x MG) to pounds
Annual C Load = Sum of the 12 Monthly Loads for each compound for the calendar year
c. The Permittee shall report monthly HFPO-DA and PFMOAA results t(% removal, ng/L, and Loading
(pounds/month)1 in the discharge monitoring report for each month and shall report each calendar year's
Annual Load results (pounds/year) with the December report for that year. This can be done in comment
section or as a supplemental information with the eDMR.
In addition, calculations shall be submitted electronically with all PFAS data to NPDES Permitting via
email at svc deq [e-mail], with the Facility permit number and name in the subject heading,
