b. All reporting requirements are to be submitted in a DEQ-approved format, unless otherwise specified in
writing.
c. Quarters are defined as: Q1: Jan – Mar, Q2: Apr – Jun, Q3: Jul – Sept, Q4: Oct – Dec. If no discharge
occurs during the quarter, continue sampling quarterly until 4 sets of samples have been collected. WET
tests and toxics characterization testing must be collected on the same day.
2. Monitoring and Reporting Protocols
a. Electronic Submissions
The permittee must submit to DEQ the results of monitoring indicated in Schedule B in an
electronic format as specified below.
i. The permittee must submit monitoring results required by this permit via DEQ-
approved web-based Discharge Monitoring Report (DMR) forms to DEQ via electronic
reporting. Any data used to calculate summary statistics must be submitted as a separate
attachment approved by DEQ via electronic reporting.
ii. The reporting period is the calendar month.
iii. The permittee must submit monitoring data and other information required by this
permit for all compliance points by the 15th day of the month following the reporting
period unless specified otherwise in this permit or as specified in writing by DEQ.
b. Test Methods
The permittee must conduct monitoring according to test procedures in 40 CFR part 136 and 40
CFR part 503 for biosolids or other approved procedures as per Schedule F.
c. Detection and Quantitation Limits
i. Detection Level (DL) – The DL is defined as the minimum measured concentration of a
substance that can be distinguished from method blank results with 99% confidence.
The DL is derived using the procedure in 40 CFR part 136 Appendix B and evaluated
for reasonableness relative to method blank concentrations to ensure results reported
above the DL are not a result of routine background contamination. The DL is also
known as the Method Detection Limit (MDL) or Limit of Detection (LOD).

Page 15 of 56 Pages
Revision 7.2021 Version 3.1
iii. When concentration data are above the DL, but below the QL: To calculate the mass
load from this result, use the detection level. Report the mass load as the calculated
mass load preceded by “e”. For example, if flow is 2 MGD and the reported sample
result is e1.0 µg/L, report “e0.02 lb/day” for mass load on the DMR (1.0 µg/L x 2 MGD
x conversion factor = 0.017 lb/day, round off to 0.02 lb/day).
3. Monitoring and Reporting Requirements
a. The permittee must monitor influent at the plant headworks, following the bar screens and prior
to grit removal, and report results in accordance with the table below.

Notes:
a. In the event of equipment failure or loss, the permittee must notify DEQ and deploy new equipment to
minimize interruption of data collection. If new equipment cannot be immediately deployed, the
permittee must perform grab measurements. If the failure or loss is for continuous temperature
monitoring equipment, the permittee must perform grab measurements daily between 2 PM and 4 PM
until continuous monitoring equipment is redeployed.
b. When submitting DMRs electronically, all data used to determine summary statistics must be submitted
in a DEQ-approved format as a spreadsheet via electronic reporting unless otherwise directed by DEQ.
c. Percent Removal must be calculated on a monthly basis using the following formula:
=[ ][ ]
[ ] × 100
Where:
Influent Concentration = Corresponding Monthly average influent concentration based on the analytical
results of the reporting period.
Effluent Concentration = Corresponding Monthly average effluent concentration based on the analytical
results of the reporting period.
d. Compliance reporting for the interim ETLL must be calculated and reported from permit issuance until
the compliance schedule in Schedule C has been completed. The weekly average interim ETLL (Billion
BTUs/day) will be calculated as follows: 7-day rolling average flow (MGD) x 1,000,000 x 8.34
(lbs/gallon) x (7-day rolling average of daily maximum effluent temperature in °F - 64 °F). Results must
be reported in Mkcal/d and must be converted using the following equation: Billion BTUs/d x 252.164.
e. Compliance reporting for the final ETLL must begin on the date the compliance schedule in Schedule C has
been completed. The daily excess thermal load (ETL) discharged must be calculated using the daily
maximum effluent temperature and the corresponding daily average effluent flow using the formula
below. The 7-day rolling average is then calculated from the daily ETLs. 7-day average periods must not
include daily ETLs outside of a limited period or daily ETLs with different criteria.
The daily ETL is calculated as follows: ETL= 3.785
Where:
ETL = Excess Thermal Load (million kcal/day)
Qe = Daily Average Effluent flow (MGD)
Daily Maximum Effluent temperature (°C) minus ambient criterion (See below, °C)
Criterion = 18ºC (May 16–Oct 14)
Criterion = 13ºC (Oct 15–Oct 31 and April 1–May 15)
f. If the permittee selects the final Excess Thermal Load Limit (ETLL) Option B from Table A1, then the
permittee must calculate the ETLL (million kcal/day) each day the permittee uses this option. The
permittee must use the equation and procedure noted in Table A1.
g. The 7-day Rolling Average for any day is the average of the daily values for that day and the preceding
six (6) days. The maximum 7-day Rolling Average is the maximum value from this series of 7-day
averages.
h. Reporting of thermal trading credits must begin on the date that the final ETLL takes effect.
i. Dissolved oxygen must be measured by calculating the average of 6 grab samples collected over a 24-hr
period.

5. Copper Biotic Ligand Model and Aluminum Parameters
The permittee must monitor the Willamette River upstream of Outfall 001 and the effluent for Outfall
001 for copper biotic ligand model and aluminum parameters per Table B6 below. Samples must be
collected twice per year, in alternating quarters (example: Year one (Q1 and Q3), year two (Q2 and Q4),
for at least five years or until the permit is renewed and not to exceed 24 data sets. This monitoring must
begin in the first year that the permit is effective. Effluent and ambient monitoring must be conducted
concurrently.
Upstream/Ambient samples must be taken in a location outside of the influence of the effluent using
appropriate sampling techniques and procedures. It is the responsibility of the permittee to ensure safe
and practical sampling techniques and procedures are used. DEQ recommends that these procedures be
included in a sample and analysis plan that can be reviewed by DEQ when necessary.
