CITY OF MERIDIAN
WWTP AMMONIA DATA ANALYSIS
RROJECT UNDERSTANDING AND SCOPE OF WORK
The City has received a draft new National Pollutant Discharge Elimination System permit
that includes a requirement to meet very low levels of ammonia concentration that vary
according to season. The Plant's historical level of performance shows that these low levels
are unattainable under current operating conditions. As a first step to developing a method of
complying with the new requirement, the influent has been monitored for changes in
ammonia and total Kjeldahl nitrogen concentration on a diurnal basis. Such data will reveal
whether the Plant is receiving influent concentrations that are higher than would occur as a
result of diurnal variability.
Dr. Henryk Melcer will provide technical analysis in support of analyzing and interpreting data
that have been, and will be, collected at the City of Meridian (City) Wastewater Treatment
Plant (Plant).
This task will evaluate the data collected to date and determine what corrective action(s)
could be deployed in minimizing the ammonia load to the Plant and/or alternative operational
strategies that could be deployed in achieving compliance with the proposed new permit. Dr.
Melcer will provide the evaluation and discuss the results of his analysis with Mr. Crane in up
to two meetings at the Plant. Travel expenses relating to Dr. Melcer's trip from Seattle to the
WWTP to discuss the findings are included in this task order.
