Upstream and downstream monitoring in WQ-limited waters is to be conducted
3/Week during Jun, Jul, Aug, and Sep; and 1/Week during the rest of the year.
TN, TP Monitoring
All facilities >= 0.05 MGD will monitor TN and TP
Those < 0.05 MGD will monitor if discharging to NSW
For the Neuse, Tar -Pamlico, and any other river basins classifed as NSW, use limits
and monitoring requirements according to the basin's permitting strategy.
For French Broad, Broad, Savannah, New Watauga, Little Tennessee, and Hiwassee:
- >= 0.05 M: - monitor semiannually
- >= 1.0 MG - monitor quarterly
For all other river basins:
- >= 0.05 M: - monitor quarterly
- >= 1.0 MG - monitor monthly

9/11/2013 rdb
New freshwater RPA based on 95% probability/95% confidence
Statistically 58 points are the maximum number of points allowed under this RPA program. Data fields were estbalished to allow only 58 data point entries.
Additional messages will appear to alert user if more than 58 data points were enter and no predicted values will be calculated
All worksheets are "Protected"
The "mf calculator" is password "Protected"
OTHER CHANGES FROM PREVIOUS RPA PROGRAM:
A. When Model is applied (Check box activated):
1) assumes only chroinc dilution known
2) assumes user will insert appropriate flow values for "7Q10s (cfs)", "7Q10w (cfs)", "30Q2 (cfs)", "QA (cfs)" to define chronic dilution in terms of "IWC %", "IWC %" is the same for all stream flows
3) automatically assigns the entered chronic IWC % to the "IWC @ 7Q10s", "IWC @ 7Q10w", "IWC @ 30Q2", "IWC @ QA" values used in chronic WQS calculations (See "RPA" page)
3) "1Q10s (cfs)" automatically defaults to no acute dilution, acute IWC = 100% ,"IWC @ 1Q1Os" = 100% which is used in acute WQS calculatons (See "RPA" page)
B. When Model is not applied (Check box NOT activated):
1) assumes user will insert appropriate flow values for "7Q10s (cfs)", "7Q10w (cfs)", "30Q2 (cfs)", "QA (cfs)" , "Flow Qw (MGD)" for chronic IWC % calculations, IWC % will vary according to flows
3) automatically calculates chronic -based IWC % for the "IWC @ 7Q10s", "IWC @ 7Q10w", "IWC @ 30Q2", "IWC @ QA" values used in chronic WQS calculations (See "RPA" page)
3) "1Q10s (cfs)" is automatically calculated bases on entered "7Q10s (cfs)" flow
4) automatically calculates acute -based IWC% for the "IWC @ 1Q1Os" value used in acute WQS calculations (See "RPA" page)
C. When paremeter's "Impaired?" check box is activated:
1) automtically activtes the "IMPAIRED" message alert on the "RPA" page for that parameter
2) does NOT make any automatic adjustements to WQS calculations
NOTE: If new or expanding discharge and receiving stream impaired, will need to evaluate if additional waste load is allowed
10/30/2013 rdb
1) Amended "ERP" alert on data sets entreies to activate if "<" entered but no value entered, does not effect RPA calculation, ERR message only
2) Added new calculation feature to count nondetects when both "<" and a value are entered for each data set, used to calculate detected entries
3) Amended "Comments" drop down menu - per Juile
4) Turned the Chronic toxicity concentration message off on the RPA page - per Julie
2/10/14:
ON "data" page changed highlighted area from blue shades to gray
5/2/14 rdb
1) Increased rounding factor on all calculated IWC% to 7 decimals
2) Increased display for all calkculated to 6 decimals places.
5/5/14 rdb
Increased rounding factor on all calculated IWC% to 9 decimals

Dissolved to Total Metal Calculator
Do NOT enter any data directly into this spreadsheet.
Enter data onto "Table 1" under the Input Sheet and enter
"Effluent Hardness" under the Data Sheet.
In accordance with 40 CFR 122.45 (c ), permits are, have and
must be written as total metals.
This calculator has been inserted into the RPA to calculate Total
Metal allowable allocations once Table 1 has been completed
(Input Sheet) and Effluent hardness has been entered (Data
Sheet).
1) Following the spreadsheet from left to right. First
the allowable allocations for the dissolved metals will
appear for all the metals listed once Table 1 is complete and
effluent hardness entered. Use a default value of 25 mg/L if
no hardness data is available. Second, the
Dissolved Metal allocations are divided by the Translators to
determine the Total Metals that can be allocated to the
Permittee. These Total Metals values are automatically
inserted into Table 2 and are the allowable Total Metal
allocations determined for the Permittee prior to allowing
for dilution. See Input sheet Table 2. The final acute and
chronic values shown under the RPA sheet are the Total
Metal values listed in Table 2 divided by the acute and
chronic IWC, respectively.
2) The Translators used in the freshwater RPA are the Partition
Coefficients published by US EPA in 1984. They are TSS
dependent equations and can be found listed with the WQS
hardness dependent equations under the sheet labeled
Equations. A fixed TSS value of 10 mg/L is used to calculate
the Translator values.
3) Pretreatment Facilities - PERCS will need a copy of the
Dissolved to Total Metal Calculator spreadsheet and the
RPA sheet along with the Final Permit. Pretreatment
Facilities are required to renew their Headwords Analysis
after renewal of their permits. Since all their metal
allocations are likely to change PERCS needs to see any new
metal permit limits and the allowable allocations for the
dissolved metals to assess Maximum Allowable Headworks
Loading (MAHL) numbers for each metal based on the
Combined Hardness values used in the permit writers RPA
calculations.
4) For Cadmium, Lead, Nickel, Chromium and Beryllium, if all
the effluent sampling data for the last three to five years
shows the pollutant at concentrations less than the Practical
Quantitative Level (PQL), it is not likely a limit or monitoring
will be put in the permit. However, if the estimated NPDES
permit limit is less than the Practical Quantitative Limit

I. How to Determine Hardness for use with Dissolved Freshwater Standards for Permitting Purposes
HARDNESS - Use 25 mq/L, expressed as CaCO, or Ca+Mg, as the default Hardness
OR
To determine a Hardness value for permit limit development, use the following equation:
Hardness
(mass balance)
(Hardness instream(a), ma/L * 7Q10, MGD)+(Hardness effluent(b), ma/L* Plant flow, MGD)
(7Q10, MGD + Plant flow, MGD)
(a) Use the median instream Hardness value of the ambient 8-digit HUC data collected by the Division of Water Quality. To find the 8-digit HUC ha
(b) For the purpose of this estimation, use the facility's median effluent Hardness value, if available. The Division will request the permittee to sample effluent harc
